Write down about different types of programming languages based on evolution history.

Based on evolution history, programming languages are divided into these three broad categories, they are as follows,

Write short notes on Optical Storage Device

Storage Device:

Those memory devices where we can store data and the data remains in it even without electricity are called storage devices. Along with various programs and system software, user can also keep, delete, move, update the data in storage devices, while this can not be done in memory devices by the user.

Storage devices are very important, along with the need storage for our data, the system software needs to store it's necessary file and configuration even when the computer has no electricity. 

There are primarily 2 types of storage devices; one of those are Optical Storage Devices.

Write short notes on "Magnetic Storage Devices"

What is software? What are the various types of software.

Software:

Software is a set of instructions that make the computer perform tasks. In other words, software tells the computer what to do.

Though the array of available programs is vast and varied, most software fall into two major categories; system software and application software.

"Software brings the machine to life" - Justify this satement.

Software Brings The Machine to Life:

The ingredient that enables any computer to perform any task is software, which contains instructions. Set of instructions that drive a computer to perform specific tasks is called a program. These instructions tell the machine's physical components what to do; without the instructions the computer can not do anything.

Describe various kinds of key groups in keyboards

Keyboard:

Keyboard is an input device used to enter text, numbers and many more symbols and commands into the computer system.

Standard Keyboard Layout:

Keyboard comes in many styles or layouts. The various models differ from shape, size and feel. Among the IBM compatible computers, the most common keyboard layout is the IBM Enhanced Keyboard. It has about 100-104 keys on it. There are six groups of keys.

Differetiate between disk and diskette drives

Differences between disk and diskette drives:

The differences between disk and diskette drives are as follows.

How the computer accepts input from the keyboard?

Accepting Input from Keyboard:

When we press a key, a tiny chip in the keyboard called keyboard controller notes that a key has been pressed. Keyboard controller places a coed in the buffer of the keyboard to indicate which key was pressed. Keyboard buffer is a temporary memory of the keyboard controller. The keyboard controller sends a signal to the system software notifying that something happened at the keyboard.

"Keyboard is considered as an input device" - why?

Input Device:

As it's name implies, input devices are devices which can send signals to the CPU. That means, the device we use to send or enter a signal or data to CPU are called input device, such as; keyboard, mouse, microphone etc.

Describe the basic four parts of computer

No matter how big it is or how it is used, every computer is a part of a system. A complete computer system consists four basic parts, such as; (a) Hardware (b) Software (c) Data (d) User

Write short notes on desktop computers, workstations, notebooks, tablet PCs, handheld PCs and smart phone

Desktop Computers:

The most common type of computer is desktop computers. It has been designed to sit on a desk. Today's desktop computers are much more powerful than the others and used for an amazing array of task. Not only do these machines enable people to do their jobs with greater ease and efficiency, but they can be used to communicate, produce music, edit photos and videos and play sophisticated games and much more.

What do you mean by modern computer?

Modern Computer:

In basic terms, computer is an electric device that process data, converting it into information which is useful to people. Any computer regarding of its type is controlled by programmed instructions which give the machine a purpose and tell it what to do.

The word 'computer' comes from the word 'compute' which means nothing but to calculate something. Computer can perform calculations with accuracy beyond human reach.

Compare between the working procedure of a computer and a human being

Comparison Between the Working Procedure of a Computer and a Human Being:

There are some similarities between the working procedure of a human being and a computer. The main deference is that human has a sense using which it takes decisions and perform a task by itself, whereas a computer need instructions or data to perform a task.

Otherwise, both of them work through a similar way. Such as first of all these take input and then processes the input to generate output (if necessary).

Differentiate among the different types of digital computers in respect of their size, cost and working efficiency

There are 4 kinds of digital computers in respect of their size, cost and working efficiency;such as (a) Microcomputer (b) Minicomputer (c) Mainframe Computer and (d) Super Computer

"Computer can be classified into 2 or 3 ways depending on it's implementation or working principle" - Explain

Depending on implementation computers can be classified into 2 ways, such as, (a) General Computer (b) Special Computer

What is Software Piracy or Copyright Infringement of Software? What should be done to prevent software piracy?

Software Piracy or Copyright Infringement of Software:

Using, modifying, distributing, selling a software without proper license or permission or right is termed as software piracy. A software should only be used as per its license. When a software is covered with copyright laws and gets used in a way that violates one or more conditions, then this use of the software is a copyright infringement of software and this is software piracy.

What are the characteristics of Third Generation Computers?

Third generation (1965 - 1971):

Use of integrated circuits (IC) started the third generation of computer. IC reduced the size, price, use of electricity etc. IC also facilitates speed and reliability of computers. Development of IC enabled organizing the whole central processing unit in single chip. Use of monitor also started in this generation. Operating system was improved to a new level and high speed line printers were in use. Followings are some of the characteristics of third generation.
