INTRODUCTION

Information Communication Technologies (ICT) is the combination of computer-based technologies (such as computing devices and smartphones) with communication technologies (such as telephones, cell phones and the internet). In practice, it refers to all the hardware, software, and systems essential to communicate electronically.

Over the last twenty years, the field of ICT has grown from a small niche field to one of the most important fields in the world. Refer to the YouTube video to see how ICT has changed over the years.

UNIT
1.1 General model of a computer

  • define Information and Communication Technologies (ICTs) and Information Technology
  • provide an overview of a general model of a computer
  • explain the information processing cycle.
ICT SYSTEMS AND IT

Information and Communication Technologies (ICT) refers to technologies that capture, transmit and display data and information electronically and includes all devices, applications and networking elements that allow people to connect in a digital world.

An ICT system refers to the overall set-up, consisting of hardware, software, data and its users. ICT systems as a whole include:

  • People – to supply the data and to make decisions from the output supplied from the system information, which is based on the results from processing data and the output from an ICT system.
  • Hardware e.g. input devices, storage, processor, output devices and communication devices.
  • Procedures – to determine what needs to be done and when. This causes the passing of data or information between people.
  • Software – the computer programs which provide the step-by-step instructions to complete the task.
  • Data – raw material that is processed by the system to provide the information for the output provided by the system. Data can come in different formats, such as sounds, images, and videos, etc.

In order for an ICT system to function, it needs to receive, store, retrieve, manipulate and transmit data.

Computers are programmable electronic devices designed to accept data, perform prescribed mathematical and logical operations at high speed, and display the results of these operations. Computers are used in Information Technology (IT) – which is a subset of ICT. Computers store, transmit, retrieve and manipulate data for businesses and other enterprises. Computers refer to the hardware, and since computers cannot initiate functionality on their own, they start functioning as soon as they receive data to work with (to process). This data is then stored on the computer, the computer manipulates the data according to the instructions it has received, before sending the new information back to the user.

Thus, we can say that Information technology (IT) is the development, maintenance and use of computer systems, software, and networks for processing and communicating data.

THE GENERAL MODEL OF A COMPUTER

The following illustration demonstrates a general model of a computer and shows that the functions of a computer are similar to the steps of the information processing cycle. All basic computers consist of four functions: input, storage, processing and output.

IPO is often called IPOS or input, process, output, storage. The computer receives input, processes the input as per user instructions and provides output and can be stored in a desired format.Computer input is called data and the output obtained after processing it, is called information. Raw facts and figures that can be processed using arithmetic and logical operations to obtain information are called data.

The general model of computers can be used to explain how each computer (or smartphone) works.

Once you understand how a computer operates, it becomes a lot easier to think about creating your own programs. When you begin learning about coding a program, you need to understand that you must create a set of step-by-step instructions that manages the flow of information: from when your program receives data from the user, up to the point when it returns output back to the user.

1.1.1Differentiate between ICT and IT.

1.1.2List the output devices of your computer.

1.1.3Follow the guidelines below to provide a diagrammatic example of the general model of computers.

a.Draw a diagram of the five steps of the general model of computers.

b.Define each step.

c.Think about when you send a WhatsApp message. How can you apply the general model of a computer to this?

UNIT
1.2 Hardware and software

In this unit, you will learn about the following:

  • provide an overview and concepts of the main components of a computer system
  • define shareware, freeware, free open source software (FOSS) and proprietary software
  • explain the interdependency of hardware and software.
HARDWARE VS. SOFTWARE

For a computer to function properly, it must consist of both hardware and software, because the hardware and software are interdependent. This means that the one will not function without the other.

And
  • Hardware consists of the physical components of a computer, also referred to as the equipment of a computer. Hardware devices can be categorised according to their functionality on the computing device.
  • Software Application software (Apps) and System software (Operating System ) refers to the programs used to direct the operation of a computer. It also contains the instructions for how to use the software.
HARDWARE: THE PHYSICAL COMPONENTS OF A COMPUTER SYSTEM

The common physical components of a computer system that will be discussed are input (keyboard, mouse), storage (hard drive), memory (RAM), processing (CPU), output (monitor, printer) and communication (Network Interface Card, NIC).

  • Input devices are any hardware devices that allows you to input data into a computer or interact with a computer. In the past, the most popular input devices included the mouse and keyboard. These days, however, there is quite a variety of input devices. One very popular example is the touchscreen keyboard on mobile smartphones.
  • A storage device is a hardware device that allows you to store data for later use. There are many different storage devices, with each device having advantages and disadvantages. Some of the most popular storage devices include hard disk drives (HDDs) and solid-state drives (SSDs). The different storage devices will be discussed in more detail in later chapters.
  • Random-access memory (RAM) refers to a fast, temporary form of storage. All data and instructions that is currently being executed is stored in RAM. RAM is volatile, that is, all data is erased from your RAM when your computer is turned off. RAM is also referred to as memory.
  • Processing devices receive the data from the RAM, perform sets of instructions, and returns the processed data to the RAM. The two most important processing devices in modern computers are:
  • The Central Processing Unit (CPU) is responsible for processing general instructions. Every application makes use of the CPU to collect, decode and execute instructions as required by the application.
  • The Graphics Processing Unit (GPU) is responsible for processing the instructions that create the pictures on your screen, for example, three-dimensional games rely heavily on the GPU to create their images.
  • Output devices are devices that return the computer’s instructions, as results, to the user. Popular output devices include monitors / screens and printers.

Do not mistake the screen of a computer for the computer itself! In many films, actors destroy the screen of a computer to destroy the computer. In most situations, the computer would continue working without a screen and users would be able to use the computer as soon as a new screen is connected.

  • A communication device is a hardware device capable of transmitting an analog or digital signal over a wired or wireless connection. Examples include, a modem and a network interface card (NIC) that can be either wired or wireless
SOFTWARE: THE NON-PHYSICAL COMPONENTS OF A COMPUTER SYSTEM

Software refers to the set of instructions a computer uses to complete any instructed task. Software is the program that is operated by the hardware. These include programs such as, Microsoft Applications or InDesign Creative Suite. As a result, hardware and software are interdependent.

Remember that this interdependence means that neither the software nor the hardware can function without the other one. Hardware cannot do anything without software because it depends on the processed instructions to provide input, while software cannot function without hardware to process the user’s instructions.

The two most important types of software are:

  • system software (including the operating system)
  • application software.

One of the primary outcomes of this subject is to teach you how to write your own software. This will allow you to use the power of a computer to make your life, and the lives of the people all around the world, better and easier!

You will learn more about the different types of hardware and software and the relationship between them.

SYSTEM SOFTWARE

System software is the specific type of software that manages the flow of data and the information contained on the computer. The operating system (OS) is the most important type of system software.

Examples of operating systems include Microsoft Windows, Linux, MacOS, iOS and Android. The OS is designed to control and coordinate the tasks and functions of computer hardware.

APPLICATION SOFTWARE

Application software is a program that is built for a specific purpose, like sending a message, browsing the internet, or typing a document. Application software refers to any software that lets the user accomplish a function or create content. Application software requires system software in order to function. This type of software includes media players, spreadsheets and word processors. When multiple applications are packaged together it is called an application suite. Examples include Microsoft Office, Google Chrome, Mozilla Firefox and Skype. Games and mobile applications such as Spotify and Uber, are also considered application software.

SHAREWARE, FREEWARE, FREE OPEN SOURCE SOFTWARE (FOSS) AND PROPRIETARY SOFTWARE

Let’s have a look at the table on the next page. The table shows the differences and uses between shareware, freeware, free open source software (FOSS) and proprietary software.

When a program is developed, the developers decide whether the code is proprietary or open source software (OSS). The table below explains more about open source software.

Keep in mind that there are safety precautions you should follow when downloading free or paid software. Nothing stops the developer from bundling the software with malicious software, malware (virus, worms, or spyware) and still make you pay for it. There is also a lot of freeware that is useless or ineffective and you need to be aware of the importance of practicing good software safety, so that you can choose the best software for your needs.

1.2.1Explain the difference between hardware and software.

1.2.2Explain the interdependency of hardware and software.

Subdued growth to dominate SA’s ICT market

By KAUTHAR GOOL

Johannesburg, 15 Feb 2018

South Africa’s overall ICT market is expected to reach $21.4 billion (R248 billion) by the end of 2018, and $23.4 billion (R273 billion) by 2021, representing a compound average growth rate of 2.9%.

This is according to market research firm IDC, which hosted its IDC Directions 2018 event in Johannesburg this week.

Speaking at the event, Mark Walker, associate vice-president for Sub-Saharan Africa at IDC, said this is in line with overall macro-economic growth expectations which are relatively subdued.

According to Walker, IT services, software and infrastructure roll-out are the fastest growth segments in SA’s ICT market.

‘The government and financial sectors dominate spend in South Africa,’ he noted. ‘In finance, this is driven by investment in upgrading legacy systems, compliance, as well as risk mitigation and improving customer experience.’

He pointed out that government spend is focused on maintaining and upgrading existing systems while rolling out infrastructure and improving connectivity as progress is made on various discrete smart city initiatives.

UNIT
1.3 Types of computers

  • state and differentiate between the types of computers
  • categorise computers/classification of computers.

Wouldn’t it be fantastic if each morning, 10 minutes before your alarm goes off, your coffee machine automatically pours you a cup of coffee, tea or hot chocolate, your toaster makes fresh toast, your lights slowly turn on and music starts playing?

Less than 15 years ago these concepts could only be found in science fiction films. Today, thanks to the development of affordable computers, all these smart devices exist and are ready to make your life more comfortable. These devices are generally called smart devices or embedded computers and are one of the five types of computers you can find today.

Supercomputers, mainframe computers, minicomputers, microcomputers and mobile computers are the main categories under which computers can be classified.

CLASSIFICATION OF COMPUTERS

Computers can be classified as general-purpose computers, specific purpose computers or super computers.

General-purpose computers compute a range of tasks but lack super speed and efficiency. The purpose of computers in this category might differ from one another: Examples are:

Disadvantages
  • desktop computers
  • laptops
  • tablets
  • smartphones.

Specific purpose computers handle a specific problem or task. It uses a high level of accuracy and processing power. Examples are:

  • servers
  • embedded devices.

Super computers are extremely expensive, and the applications are for specialised activities or tasks such as weather forecasting.

Classification of computers in terms of data processing power and capacity could be done in the following grouping:

Examples of embedded computers are:

  • ATM machines
  • MP3 players
  • DVD players
  • Drones
  • Anti-lock braking system
  • Airbag control system
  • Digital watches.

1.3.1Identify the different types of computers illustrated below.

1.3.2Differentiate between the six types of computing devices.

1.3.3Which of the devices below are examples of embedded devices? Support your answers.

a.Mobile phone

b.Navigating system in a motor vehicle

c.A tablet

d.A robotic vacuum cleaner

d.Television decoder

UNIT
1.4 Advantages and disadvantages of using computers

  • list the advantages and disadvantages of using computers.
ADVANTAGES OF USING A COMPUTER

There are many advantages of using computers. However, the following are some of the most important ones to know:

1.Provides access to more information

2.Completes tasks that might be impossible for humans to complete

3.Saves time

4.Automates repetitive tasks

5.Allows for greater productivity

6.Allows for better communication and connections

7.Entertainment

DISADVANTAGES OF USING A COMPUTER

Unfortunately computers also have some disadvantages. These disadvantages include:

1.Social risks: computers provide humans access to social media, which can be addictive, make people less happy, lead to jealousy, and get in the way of real-world friendships. In fact, a study found that of 1 500 Facebook users interviewed, 62% said Facebook occasionally made them feel like they are not good enough, and 60% said that comparing themselves to other people on Facebook made them jealous.

2.Health risks: research has shown that excessive computer use can result in several medical problems, including back pain, eyestrain, obesity, carpal tunnel syndrome (CTS) and repetitive strain injury (RSI). However, with good ergonomic practices, many of these health risks could be reduced or removed.

RSI (REPETITIVE STRAIN INJURY) – a painful inflammation of the tendons that often results from overuse. A tendon is tissue that attaches muscle to the bone

ergonomics – the study of how humans interact with fabricated objects, the goal is to create an environment that is well suited to the users’ physical needs

3.Security risks: computer security risk can be created by malware, that is, bad software, that can attack your computer system, destroy your files, steal your data, or allow an attacker to gain access to your system without your knowledge. Computers are programmed to follow instructions, and sometimes people program computers to act in a way that harms a user.

4.High cost: computers are expensive. Even the most affordable computers are still very expensive for the average person in South Africa. Since computers empower people, the high cost of computers puts pressure on people who are not able to afford them, and places them at a disadvantage.

5.Distractions/disruptions: if you have ever spent hours browsing the internet or watching videos on YouTube, then you know how distracting computers can be! Because of their high entertainment value, it is easy for computers to distract people and stop them from being productive.

6.Environmental impact: computers use a lot of electricity and in most cases the generation of electricity is harmful to the environment because of the carbon emissions. This has a huge impact on our planet.

1.4.1List any TWO advantages of computers.

1.4.2.List any TWO disadvantages of computers.

1.4.3.What do you use a desktop computer for?

1.4.4.In two teams, debate for and against the use of computers. Support your answers.

UNIT
1.5 Data and information management

  • explain and differentiate between data and information
  • provide an overview of uses and examples of information within an organisation
  • explain why information is useful
  • provide an overview of a general model of an ICT system.

So far, we have spoken a lot about computers receiving data, manipulating the data, and then turning data into useful information. But what exactly is data and how does it differ from information?

Data can be defined as unprocessed numbers, or facts. Without first processing or changing data, it is meaningless. For example, your school might have data on the names, surnames, addresses, contact details, as well as the results of every class test, assignment, test, and exam of all current and past learners stored on a computer somewhere. While this data is important to store, it could be hundreds or even thousands of pages long and very difficult to interpret!

Information can be defined as facts and numbers that have been organised / processed so that it is useful / meaningful to people. For example, if your mathematics teacher wanted to see how well your current class is performing compared to last year’s class, she might ask your school’s database administrator to process the available data into averages for the two years. In that way, all those thousands of pages of data are processed into two numbers that can be compared easily. Similarly, the report you receive at the end of each school year takes all the data that teachers have collected during the year and turns that data into a single report that you can use to measure your performance.

One of the main functions of a computer is to take unprocessed data (data that is useless to humans) and then turn it into something that is meaningful and easy to understand for humans.

OVERVIEW OF AN ICT SYSTEM IN ORGANISATIONS

Information is useful in an organisation because it will speed up the decision-making process, and help the business to improve their business service offering.

For example, supermarkets and chain stores use ICT systems for a variety of reasons. Let’s look at an example of a Point of sale (POS) system, paying special attention to the processes of receiving, storing, conveying, and manipulating data.

EXAMPLE OF A POINT OF SALE SYSTEM PROCESS:

From the cashier and customer’s perspective, a supermarket’s ICT system is a standalone computer, called a cash register. However, it consists of much more than that.

Most products have a barcode, which is a pattern of narrow and wide stripes that is read by a barcode reader. The barcode consists of information about the product such as, availability in store, quantities, orders, etc. The scan reader will scan the barcode optically and convert the stripes into numerical data, which is then transferred automatically to the checkout computer (cash register). The barcode reader sometimes beeps after scanning an item to signal to the cashier that the item is now identified.

Look at the IPO table below to see how this process works:

Answer the questions, which are based on the three scenarios below.

Scenario 1

Increasingly, the internet and big data are combined with mobility and social networking to allow companies to respond speedily to customer demands. Let’s use the Red Robin restaurant chain in the United States as an example.

A while ago, they tested a new hamburger across the chain and gave their frontline waiters devices on which to input customer feedback – likes and dislikes – about the burger. Normally the testing, feedback and response loop would have taken 12 to 18 months. This time round they were able to get a new, improved burger on to the menu within four weeks.

Scenario 2

In South Africa, the Johannesburg Road Agency’s (JRA) Find and Fix app allows motorists to report issues such as potholes and broken traffic lights as they encounter them, with one or two clicks on a smartphone.

Scenario 3

The internet of things (IOT) is about four big trends: social, mobile, cloud and big data; by using data and information collected through things like mobility and sensors and the cloud to make smarter, better decisions or to provide better, quicker service. It helps to collect and analyse data faster, understand customers, make decisions faster, and provide better service to customers.

Are you having a hard time deciding between custom software development and off-the-shelf software for one of the critical functions in your organization?

Choosing between the two options is, in fact, a very difficult decision to make for any manager or a leader.

Both custom software development and off-the-shelf software require a considerable investment in terms of time and cost, and also affects your company for many years to come.

You would not like to go wrong on this important decision.

You need to understand the advantages of custom software over readily built solutions and vice-versa, and evaluate all pros and cons to make a wise decision.

Custom software can be a viable solution if you chose the right kind of people who provide you with highly customized flexible solutions that are easy to use and maintain.

On the other hand, a ready built solution saves a lot of your time and initial investment.

There are various factors that can help you decide on the right option for your organization.

This includes complexities of your work, the size of your organization, your future plans for growth and of course the most important, financial viability of the solution.

Before you make a final decision, it is important to understand the advantages and disadvantages of each option in detail and cases where custom software may be better suited over off-the-shelf software and vice-versa.

Let’s first have a look at what are the advantages of custom software.

  • Advantages of Custom Software
  • Disadvantages of Using Custom Software

Advantages of Custom Software

Readily available solutions are built on the basis of generic requirements in the category for which it is built which may not fit the way your operations work.

Sometimes, businesses need unique solutions to solve problems specific to their organizations.

Custom Software Development is a popular option for all such companies.

Let’s look into some of the key benefits of Custom Software.

Tailor-made Solution

When you purchase off the shelf solutions, they may or may not be built around your business goals.

Developing a software solution specifically for your company ensures that it is tailored to suit your needs.

In fact, during the process of building custom software, you may find several opportunities to optimize your processes, which leads to higher productivity for your organization.

There are several outsourcing partners who would be willing to analyse the complete set of processes followed within the organization to give you highly optimized solutions for automation.

This will increase your productivity, which in turn makes it financially more rewarding in the long run.

Check out our portfolio page to find out what custom tailored solutions we have created for our customers.

Return on Investment

Custom software development may look like an expensive option at the beginning as a lot of investment is involved in software development but in the long run, they may get you higher returns.

On the other hand, readily built software packages also involve some cost.

At times you may need to purchase extra hardware, high-end servers (sometimes even with version updates) to run them effectively. The additional cost that you need to bear every year is annual license fees.

Custom software is high on investment at the beginning but the costs become almost negligible in the long run.

A detailed ROI needs to be done to find out paying huge sums for custom software development which will pay for itself in few years vis-à-vis license fees during the same period and other costs involved in buying off-the-shelf software.

Security Concerns

One of the benefits of custom written software is that security, as required by your organization, can be inbuilt in the software.

Hackers love the popular commercial off-the-shelf software (COTS) and are more likely to find ways through vulnerable portions of such tools to enter your systems.

With custom software, chances on intrusion are considerably reduced as you use your own tool which is predominately used by your own team.

Flexibility

Scalability can be built into custom software easily.

This will ensure that the software addresses any changing needs of your organization. On the other hand, features of an off-the-shelf application remain constant more or less and cannot be manipulated easily.

With off-the-shelf software, you will have to wait for some other company to enhance their features to make your life easier.

This is not the case with custom software, you have a team in hand who can take up all your requests at any time and enhance the features for you.

In case you are outsourcing development to another company, it is always better to ensure maintenance is built into your contracts and they are flexible enough to incorporate any changes that you may need at any point of time.

An agile and flexible team is what you need.

Compatibility

There may be several other tools that your organization may be using.

You may want that all the tools talk to each other and may need to build interfaces which makes it easy to transfer data from one application to other.

These functionalities are very difficult to obtain in an off-the-shelf tool.

This compatibility can, however, be built in a custom software. Off-the-shelf software may have some options to integrate with other software but this may not be too seamless as you may want it to be.

Easy to Operate

Advantages And Disadvantages Of Special Purpose Software Technology

Another advantage of custom software is that they are easy to operate as they are not bulky and have just enough features required for your operations.

Off-the-shelf software may have a lot of functionalities based on a generic set of requirements.

You may not be needing many of these functionalities and may be using just some features. The tools become bulky and difficult to operate due to this.

The ease of use increases productivity and reduces costs by automating repetitive tasks. This will increase your profits and lower the cost involved further.

Long-term Risks

Many times, off- the- shelf companies release newer versions of their software and they stop all support for older versions.

Companies also go bankrupt and stop providing any support altogether.

You don’t run such risks if you go for custom software.

You can run your business without worrying about an off-the-shelf software that is being used to run your entire business or a critical function may be discontinued and no further updates or improvements can be received.

A custom software is always available and can be updated as many times as you may want.

Improved Software Support

You get better support from teams working on custom software than off-the-shelf software.

Most of the time, continuous support is built into your contracts with outsourcing partners which means there will be a dedicated team that they will provide you to maintain the software.

Advantages And Disadvantages Of Special Purpose Software Examples

This provides better problem solving and defect fixing than the support provided by off-the-shelf software.

The response and resolution time are faster with custom software development and this can be ensured by building Service level agreements (SLAs) in your contracts.

The control of support that you will receive is in your hands and not the other way around.

Competitive Advantage

A custom software is made exclusively to suit the needs of your business.

You can get all kinds of unique features built into the system which your competition may not have.

You have a unique solution in hand which can become your USP (unique selling proposition) and gives a competitive advantage to you over your competitors. An off-the-shelf software is rigid and you need to align your processes against it.

With custom software, you have what you need and you can focus on your target audience better.

This can ensure higher customer satisfaction and more business for you in the long run.

Disadvantages of Using Custom Software

Now that numerous advantages of customized software are listed, let’s look at the flip-side of using custom software.

High Investment

As we discussed above, a huge investment is required to develop a custom-built software.

While it may pay in the long run, the initial investment may be a little overwhelming for some organizations.

A good ROI should be done before deciding on the custom software.

Time Involved

Apart from investment in terms of money, a huge time investment is required to complete the software development process.

While off-the-shelf solutions will give benefits quickly, it may take months or years to actually get the custom software delivered.

The organization need to invest a lot of their time in providing requirements to the outsourcing company or to your in-house software development team.

An off-the-shelf software has been tested for all defects, has gone through elaborate usability tests and is ready to use when it reaches your desk.

This may not be the case with custom software.

The custom software requires investment in terms of time to test the software from a user’s perspective and the process may go through several iterations before you get the desired results.

This whole time spent in various software development phases may be draining for you or the teams working with the outsourcing partner.
