Full Form of Computer, Different, Types, Computer Generations, List of Computer-Related Full Forms

The full form of a Computer is “Common Operating Machine”. It is Particularly Used for Trade, Education, and Research. As we know the full form of a Computer, let's now discuss What a Computer Is? 

A computer is an electronic device that accepts raw data (Input) from the user and processes the data under a set of instructions (known as a program) to produce the result (known as output). The term computer is derived from the Latin word "Computer" which means to calculate. 

A computer is a machine that can store and process information. Most computers rely on the binary system, which uses variables 0 and 1 to complete different tasks such as storing information, performing algorithms, and displaying information. Computers come in different shapes and sizes, from minicomputers to supercomputers weighing more than 300 tons.

What Are The Different Parts of A Computer?

The different parts of a computer include the following:

1. CPU (Central Processing Unit): The CPU is known as the brain of the Computer. It contains the processing power that interprets and executes commands from the user.
2. Motherboard: This is the circuit board that connects all of the internal components of the Computer and contains the main logic processor of the Computer.
3. Memory: Memory can store information that the Computer needs to access quickly. It usually consists of RAM (Random Access Memory) and ROM (Read Only Memory).
4. Hard Drive: This is where the operating system and the data are stored.
5. Optical Drive: The optical drive allows you to access information stored on a CD or DVD.
6. Monitor: The monitor allows you to view the output of your Computer.
7. Keyboard: The keyboard helps you input information into the Computer.
8. Mouse: The monitor allows you to control the cursor on the monitor.
9. Speakers: With a speaker, you can listen to audio from your Computer.
10. Network Interface Card (NIC): The NIC connects the Computer to a network, allowing for file transfer, access to the internet, etc.

What Are The Different Types of Computers?

Computers, based on their size, are split into 5 different types. These are 

• Supercomputers: These computers perform at or near the highest operational rate compared to a general computer. 
• Mainframe computers: These are the computers known for their large size, storage capacity, processing power, and higher level of reliability.
• Mini Computer: These computers have a similar level of functionality and features as large computers but are available in small sizes.
• Workstation: Workstation computers are powerful desktop computers specifically designed to run applications requiring the greatest possible amount of processing power. They are typically used by professionals such as graphic designers, engineers, and scientists.
• Personal Computers: These are general-purpose, cost-effective computers designed for one person at a time.

Based on their data-handling abilities, computers are split into 3 different types. 

• Analog computers: These computers process information by continuous physical magnitudes such as voltage, pressure, temperature, or displacement, representing specific variables within a problem or system. Analog computers are often used for tasks that require a greater degree of precision than is possible with digital Computers.
• Digital Computer: These are electronic devices that store, process, and manipulate data, allowing for more complex calculations than those of analogue computers. These computers often process large volumes of data quickly and accurately, providing powerful, reliable, and consistent results.
• Hybrid Computer: These types of computers offer the functionality of analogue and digital computers.

Computer Generations

The development of the Computer is split into 5 different generations. The explanation of each Generation is discussed below:

First Generation (the 1940s - 1956s): The first Generation's computers used vacuum tubes as their basic logic elements. These types of computers had a large amount of heat and could store large amounts of information. Examples of first-generation computers include ENIAC, UNIVAC1, IBM 650, IBM 701, etc.

Second Generation (1956-1963S): The second generation computers used discrete transistors as their basic logic elements instead of vacuum tubes. These Computers were smaller in size, had low power consumption, and generated less heat than the first-generation computers. The use of transistors made it possible to perform powerfully and with due speed.

The use of transistors also helped computers to perform powerfully and with greater speed. A few examples of first-generation computers include PDP-8, IBM 7090 and 7094, IBM 1400 series, UNIVAC 1107, CDC 3600, etc.

The Third Generation (1964-1971): The third generation computers used integrated circuits instead of transistors. The integrated circuit was made from silicon, also known as a silicon chip. The most notable feature of this Generation of Computer was speed and reliability. 

The value size was minimized during this Generation, whereas memory space and dealing efficiency were enhanced. A few examples of third-generation computers include IBM 360, IBM 370, PDP-11, NCR 395, B6500, UNIVAC 1108, etc.

The Fourth Generation (1971-Present): This period saw the introduction of microprocessors, which allowed for much more powerful and sophisticated computers to be built. The most notable benefit of this type of technology was that one microprocessor could contain all the circuits required to perform logic, arithmetic, and control functions on one chip. 

This was also the era when smaller computers with larger capacities were introduced. A few examples of fourth-generation computers include IBM PC, STAR 1000, APPLE II, Apple Macintosh, Alter 8800, etc.

The Fifth Generation: This period saw the emergence of Artificial Intelligence. Technology allows computers to behave like humans. This type of technology is generally observed in medicines and entertainment. The size of the fifth-generation Computer is the smallest, and the speed is the highest. This is also the period of the internet, where computers are connected across the world and sharing data and applications. A few examples of fifth-generation computers include Desktops, laptops, tablets, smartphones, etc.
