DESCRIPTION
Computers have become an integral part of our education system. Computer Science is now not limited to just teaching definitions and commands. Instead, it helps the learners to understand and appreciate the varied uses of computers and its vast applications.
Trackpad iPRO (Ver. 4.0) series based on Windows 10 and MS Office 2019 is comprehensively designed as per the new ICSE syllabus. We believe computer education is a hands-on subject and too much of bookish knowledge can take away the pleasure of learning. All these points have been kept in mind while designing this book and to produce the content that is not only appealing but also challenging to the students.

The topics in the book have been hand picked after extensive research by a team of experts on the subject based on the utility, interest, skill, and basic and trending applications in the global market. We have designed the lessons in such a way that they can be well integrated with other subjects. Step by step approach will make it simple and easy for our students to grasp the concepts. Relevance of the topics was of prime importance throughout the compilation of the book.


Learning is done best when it’s fun-filled and activity-based. To ensure that the content intrigues the students at all times and keeps them interested throughout the course of the book, we have included interesting key features like Student Corner, Tech Funda, Clickipedia, Comp Caution, Reboot, One Touch Learn, Let’s Do It, Crack The Code, Hands-On, Fun In Lab, Teacher’s Corner, Worksheet, Test Sheet, Project, Speech Drill, Supplement Pages and Glossary.

These features will ensure better learning, assessment, and evaluation and enable children to take their knowledge beyond the classroom.

Sample questions of Orange Global Olympiad (Cyber) have been included to promote awareness about the national level competition.

We hope that the book contributes to the progressive development of computer aided education system and prepares our students for all upcoming challenges. We want the children to learn the concepts not only for the purpose of gaining knowledge but also to be able to find their applications. This will enable them to enrich the quality of their lives as well as others’.

Chapter 01

Categories of Computers and Computer Languages

As you know, a computer is an electronic device used in different places for different purposes, such as managing accounts in schools and reading at home. You have also learnt about computer programs and programming in the previous class. In this chapter, you will learn about the different types of computers and computer languages.

Categories of Computers

Nowadays, different types of computers are used that can be categorised on the basis of their:

★ Type

★ Purpose

★ Size, speed, processing power, and price

Let us learn about these categories in detail.

Type

On the basis of their type or functioning, computers can be classified into three categories, which are as follows:

An Analog Computer

★ Analog: refers to a computer that operates by measuring instead of counting. It measures continuously changeable physical quantities like voltage, pressure, water flow, etc. This type of computer generally displays the output in the form of a graph. Examples of analog computers are mercury thermometers, speedometers in cars, old radios, etc.

A Digital Computer

★ Digital: refers to a computer that uses digits (binary numbers 0’s and 1’s) to generate, process, and display data. The results produced by digital computers are more accurate than those of analog computers. All the modern computers that that we currently use, like desktops, laptops, and smartphones, are examples of digital computers. Some other examples of digital computers are digital watch, digital thermometer, electricity meter, etc.

A Hybrid Computer

★ Hybrid: refers to a computer that provides the functionality of both an analog and a digital computer while processing and displaying data. It uses the speed of an analog computer and the accuracy of a digital computer. These types of computers are generally used in scientific research and specialised applications. The heartbeat measuring machine used in hospitals is the most common example of a hybrid computer.

Purpose

On the basis of their purpose, computers can be of two types:

★ General Purpose Computer: refers to a computer that can perform different kinds of jobs with equal efficiency. Personal computers, including desktops, notebooks, smartphones, and tablets, are all examples of general-purpose computers.

★ Special Purpose Computer: refers to a computer that is used for a specific purpose. It does its single task very quickly and cannot be used for any other purpose. These types of computers are generally used for controlling the process of manufacturing and for weather forecasting systems.

Size, Speed, Processing Power and Cost

Computers differ in size, processing power, speed, and cost. On the basis of these factors, computers can be categorised as follows:

Microcomputer

A microcomputer is a type of computer that has one microprocessor as its processing unit. It is a small and less expensive digital computer. This type of computer is made to be used by a single user at a time. A Microcomputer is also called a Personal Computer (PC). Some examples of microcomputers are:

Desktop

★ Desktop: It is a personal computer developed for regular use and generally placed in a single location on a desk or a table. All its components, such as a keyboard, mouse, and storage devices, are connected through wire or wireless. Due to its size and power requirements, we cannot carry this type of computer. Desktop computers are generally used in schools, colleges, offices, etc.

Laptop

★ Laptop: It is a portable and small digital personal computer that is suitable for use while travelling. We can use a laptop computer by keeping it on our lap. A laptop computer has a built-in mouse, monitor and keyboard. It also has a rechargeable battery. After fully charging the battery, we can use the laptop computer without power for 4 hours or more. Laptop computers are mostly used by marketing executives who travel frequently and far from their offices.

Tablet

★ Tablet: It is a portable digital computer that is smaller than a laptop computer. It has a touchscreen as its primary input device instead of a mouse. Similar to a laptop, the tablet computer also has a rechargeable battery. A tablet computer generally provides fewer features than a laptop computer. Tablet computers are commonly used by professionals in various organisations.

Minicomputer

Minicomputer

A minicomputer, also known as a mini is a type of computer that is bigger, more expensive, and more powerful than a microcomputer. It can contain one or more microprocessors as its processing units. This type of computer is mainly used for scientific and engineering computations. A minicomputer has the capability to serve a number of users simultaneously. It is also known as a small or midsize server computer. Some common examples of minicomputers are PDP-11, PDP-8, HP-3000, etc.

Mainframe Computers

Mainframe Computers

Mainframe computers are very large, fast, powerful, and more expensive than minicomputers. They can have multiple microprocessors as their processing units. Some mainframe computers are so big that they require as much space as a room.

Mainframe computers are generally used in big organisations where a large amount of data is used, such as banks. Examples of mainframe computers are IBM zSeries, IBM 4381, ICL 39, etc.

Supercomputers

Supercomputers

Supercomputers are the largest and fastest of all types of computers. Even some supercomputers require as much space as a floor of a building. The cost of a supercomputer is very high. They can process a very large amount of data quickly.

They are used in very big organisations and government departments to do tasks such as weather forecasting and rocket launching. PARAM was India’s first supercomputer, developed in 1991. Some other examples of supercomputers are PACE, Titan, Sunway TaihuLight, Pratyush, Mihir, etc.

Some other Special Computers

Apart from the types of computers that we have discussed in the previous sections, some other types of computers are embedded computers and handheld computers. Let us learn about these computers in detail.

Embedded Computers

An embedded computer is a special type of microprocessor-based system that is developed for performing a specific task. It is different from a general-purpose computer like a PC. Today, embedded computers are used in various applications. Some commonly used examples of the embedded computers are the digital camera, microwave, ATM, etc. Let us learn about some of these embedded computers in detail.

Digital Camera

Digital Camera

The digital camera is one of the most commonly used embedded computers. Due to the use of embedded computers, cameras have become very smart and provide lots of features that were not present in older cameras. The main functions of a camera are to capture photos and shoot videos. It also has a memory to store the captured photos and videos.

ATM

ATM

An Automated Teller Machine (ATM) is another example of an embedded computer that allows us to withdraw money from our bank account anywhere and anytime. This machine is connected to the bank’s server. When we withdraw some money from an ATM an equal amount is debited from our bank account.

Microwave

Microwave

The microwave that we use at our home is also an example of an embedded computer that allows us to warm and cook food. It contains a computer system embedded inside to control the time and temperature.

Handheld Computers

A handheld computer is a type of computer that can easily be stored in our pockets and used by holding it in our hands. Most handheld computers have a touchscreen on which we input data by using our fingers. Some commonly used examples
