Today in this article I am going to tell you What is computer and its types.
So let’s get started…
Brief Descriptions of The Content
What is Computer Definition
A computer is an electronic device that can accept, store, process, and retrieve data. It can perform a wide range of operations on data, including calculations, sorting, filtering, and many others.
Computers can be programmed to perform specific tasks using software, and they can communicate with other computers and devices over networks.
They are used in many areas of society, including education, business, entertainment, and research. The modern computer as we know it was invented in the mid-20th century, and since then it has become an essential tool in many aspects of daily life.
Who Invented the Computer
The invention of the computer was not the work of a single individual, but rather the result of a long history of developments in mathematics, science, and engineering. The concept of a programmable machine dates back to the 1800s, with the development of early mechanical calculators and the work of pioneers such as Charles Babbage and Ada Lovelace.
However, the modern electronic computer as we know it today was developed in the mid-20th century by several key figures in computer history, including John von Neumann, Alan Turing, and Tommy Flowers. The first electronic computer, called the ENIAC (Electronic Numerical Integrator and Computer), was developed by a team of scientists and engineers led by John Mauchly and J. Presper Eckert at the University of Pennsylvania in 1946.
Since then, there have been numerous developments and advancements in computer technology, including the invention of the microprocessor, the personal computer, and the internet. Today, computers are an essential part of modern life, used in everything from business and education to entertainment and communication.
What is the Full Name of Computer
The term “computer” is derived from the word “compute”, which means to calculate or reckon. Therefore, the full name of the computer is actually “computing machine” or “calculating machine”. However, in modern usage, the term “computer” is often used as a shorthand for any electronic device that can process data, and the full name is not commonly used.
What is Computer Programming
Computer programming is the process of creating instructions (in the form of code) that a computer can understand and execute. It involves writing code in a specific programming language, which is a formal language used to communicate instructions to a computer.
Computer programming can be used to create a wide range of software applications and computer programs, from basic programs such as calculators and text editors to complex systems such as operating systems and web applications. Programmers use a variety of tools and techniques to write and test code, including integrated development environments (IDEs), debugging tools, and version control systems.
Some common programming languages include C, C++, Java, Python, and JavaScript. Each language has its own syntax and features, and is suited to different types of applications and programming tasks.
Computer programming is a fundamental skill in the field of computer science, and is used in a wide range of industries, including software development, finance, healthcare, and education.
Computer Features
There are several features that are common to most modern computers. Here are some of the key features of a computer:
- Processor (CPU): This is the brain of the computer, which performs calculations and executes instructions.
- Memory (RAM): This is the temporary storage area where the computer stores data and instructions while they are being processed.
- Storage: This is the long-term storage area where the computer stores data, programs, and files, such as hard drives, solid-state drives, or cloud storage.
- Input devices: These are devices that allow users to input data into the computer, such as keyboard, mouse, touchpad, touchscreen, or microphone.
- Output devices: These are devices that allow users to receive output from the computer, such as monitor, speakers, printer, or headphones.
- Operating system: This is the software that manages the computer’s resources and provides a user interface for interacting with the computer, such as Windows, macOS, or Linux.
- Software: These are programs and applications that perform specific tasks on the computer, such as word processors, spreadsheets, or web browsers.
- Connectivity: These are the features that allow the computer to connect to other devices and networks, such as Wi-Fi, Bluetooth, Ethernet, or USB ports.
- Graphics card: This is a hardware component that is used to process and display graphics on the computer, such as games, videos, or images.

These features may vary depending on the type and purpose of the computer, but most modern computers have these basic features.
What is Computer Software
Computer software, often referred to simply as software, is a set of instructions or programs that tell a computer what to do. Software is a collection of code that is designed to run on a computer system to perform specific functions. It includes programs, applications, and operating systems that enable users to interact with the computer.
There are two main types of software: system software and application software. System software is the basic software that controls and manages the computer hardware, such as the operating system (e.g., Windows, macOS, Linux) and device drivers. Application software, on the other hand, is designed to perform specific tasks, such as word processing, accounting, or graphic design.
Software is created by programmers using programming languages and development tools. It can be installed on a computer from a variety of sources, such as the Internet, CDs, DVDs, and USB drives. Once installed, software can be run to perform its intended functions.
Types of Computers
There are several types of computers available today, each with its own characteristics, features, and capabilities. Here are some of the most common types of computers:
- Personal computers (PCs) – These are the most commonly used computers for personal and business use. They come in various forms such as desktops, laptops, and tablets.
- Workstations – These are specialized computers designed for tasks that require high performance, such as video editing, 3D rendering, and scientific simulations.

How Does Computer Work
A computer works by processing data and performing operations according to a set of instructions called a program. Here is a simplified overview of how a computer works:
- Input: The computer receives input from various sources such as keyboard, mouse, microphone, camera, or other devices.
- Storage: The computer stores this input in its memory, either temporarily or permanently, depending on the type of data and the purpose of the operation.
- Processing: The computer’s central processing unit (CPU) interprets the input and performs operations according to the instructions of the program. The CPU uses the data stored in memory, performs calculations, and generates output.
- Output: The computer produces output in various forms such as text, images, sounds, or videos, and sends it to the output devices such as monitor, speakers, printer, or other devices.
This process repeats continuously as the computer receives more input, processes it, and produces output. The speed and efficiency of this process depend on various factors such as the processing power of the CPU, the amount and type of memory, the speed of input/output devices, and the efficiency of the software and operating system.
In summary, a computer works by receiving input, storing it, processing it, and producing output according to the instructions of a program, using various hardware and software components.
