What is Computer?A computer is a machine or device that follows instructions provided by a software or hardware program to perform processes, calculations, and operations. It can take data (input), process it, and then output results.Computers can also save data in appropriate storage devices for later use, and retrieve it when needed.Modern computers are electronic devices that are used for a variety of tasks such as surfing the web, writing documents, editing videos, developing applications, and playing video games, among others. By combining integrated hardware and software components, they are designed to execute applications and provide a variety of solutions.There are two types of computers:Hardware and softwareHardwareThe processor, memory, storage, connection ports, and auxiliary devices are all housed in this physical framework. Each of these components (known as devices) serves a specific job, such as taking inputs, storing data, or sending outputs.
A mouse and a microphone, for example, are input devices that record user behaviors and convert them into data that is sent to the system unit. A hard disk is a storage device that stores data and allows other devices to access it.
A monitor or a speaker are output devices that convert processed data into video and audio signals, respectively.
The bare minimum that allows a computer to work is usually comprised of the following essential components:
A computer processor (CPU)The component responsible for processing and executing inputs from both hardware and software.MotherboardA mainboard is a piece of hardware that connects all of the other hardware components and devices (internal and external).Recollection (RAM)A temporary data storage location that holds the information that the CPU is currently working with.Device for storing dataA storage device that stores data on a long-term basis. It's slower than RAM, but it's less volatile.
Unit for supplying power
That should be self-explanatory: no electrical equipment can function without power!
SoftwareSoftware encompasses all non-physical components of a computer, including data, programs, applications, protocols, and so on. Although software has no physical form, it is just as important to receive, encode, store, and process data.Documents, digital media, libraries, and internet information are all examples of computer software, which comprises both executable and non-executable data. The operating system (OS) of a computer, as well as all of its programs, are software.A computer reads, interprets, and executes software programs sent to its underlying hardware architecture.Personal computers (PCs), desktop computers, laptop computers, minicomputers, handheld computers and devices, mainframes, and supercomputers are all types of computers classed by computational power, capacity, size, mobility, and other criteria.
