A computer system consists of both hardware and information stored on hardware. Information stored on computer hardware is often called software.
The hardware components of a computer system are the electronic and mechanical parts.
The software components of a computer system are the data and the computer programs.
The major hardware components of a computer system are:
Input devices: Keyboard, mouse, scanner, digital camera and joystick. Peripheral device used to provide data and control signals to an information processing system such as a computer or other information appliance.
Output devices: Monitor printer, plotter and voice output device, Modem, Automotive navigation system, Projector. Peripheral device that converts machine-readable information into people-readable information.
Processing devices: CPU, Motherboard, Chipset, bus, RAM. Hardware components process information within the computer system.
Storage devices: Hard disk drives and compact disk drives. Hardware components allow data to be stored within a computer system.
Software components of a computer system have no physical presence; they are stored in digital form within computer memory.
System software is an operating system designed to operate and control the computer hardware and to provide a platform for running application software.
Utility software: anti-virus software, firewalls, disk defragmenters. Which helps to maintain and protect the computer system but does not directly interface with the hardware.
Applications software: Web browsers, Office software, Games, Multimedia Software, Database Software, and Graphic Software. Designed to allow the user of the system complete a specific task or set of tasks.
Different types of computer software.
Programming software, system software and application software are the three main types of computer software used in computer networking.
Programmers use the programming software to develop the programming languages necessary to run computer software. Compliers, interpreters, linkers and text editors are some of the basic tools used in programming software.
System software offers a protective shield to all software applications. It also provides support to the physical components of computers. System software • Operating system software(windows, Linux, Mac) • Utility programs (anti-virus software, firewalls, disk defragmenters.) • Library programs • Translator software (Compiler, assembler, interpreter)
Application software is used for commercial purpose. The application software is widely used in educational, business and medical fields. Industrial automation, databases, business software and medical software prove to be of great help in the respective fields. Web browsers, Office software, Games, Multimedia Software, Database Software, and Graphic Software. Application software • General purpose application software. • Special purpose application software. • Bespoke application software

The basic components of all computer systems whether they are microcomputers or supercomputer all contain six basic building blocks: input, output, memory, arithmetic/logical unit, control unit and files. A computer system needs input devices for entering data into the computer for processing. The most common input devices are keyboards and mice. Input devices have now expanded to other methods such as voice input, magnetic ink character recognition (MICR), Optical character recognition (OCR), scanning bar code label, etc. The output devices are used to produce the results of the processing done by the computer. The most common output devices include computer screen or monitor, printer, or writing output on CD or DVD. Computer memory or main memory holds the program instructions and data. All data flows are to and from memory. Arithmetic and Logic Unit consist of incredibly small integrated circuits on a silicon chip. It is mainly responsible for arithmetic function of addition, subtraction, multiplication and division calculation, logical comparison and decision. Computer files storage devices sometimes called secondary or backing storage is used to store programs and data when they are not being used. Secondary storage is nonvolatile. File devices include hard disk drive, magnetic tape drives, flash drives, and CD or DVD. Control Unit provides the control that enables the computer to take advantage of the speed and capacity of its other components. It controls the sequence of instruction to be executed, controls the flow of data, interpret instructions, and it regulate timing of processor (Brown et al., 2012).…

Computers are basically all around us now and they have become part of our daily living. Not only can it perform calculations much more quickly than a person can, it can also do many complex tasks simultaneously. Thanks to the computers, they help us make the complicated jobs much easier, help us to do tasks quicker and communicate with friends and family with one click, and play a significant role in the school system as well. The computer has significantly changed our world. Perhaps you already know how to use a computer, but how familiar are you with what’s inside of it? There isn't any single part called the "computer." A computer is a system of many parts working together. The computer is made up of two main parts, hardware and software. Hardware is the physical parts that you can touch and see. Software, on the other hand, refers to the instructions, or programs, that tell the hardware what to do. In the following article, I am going to introduce to you the main parts of a computer. These components include input devices, output devices, a system unit, and storage devices.…

Programming Software: This is one of the most commonly known and popularly used types of computer software. These software come in the form of tools that assist a programmer in writing computer programs. Computer programs are sets of logical instructions that make a computer system perform certain tasks. The tools that help programmers in instructing a computer system include text editors, compilers and interpreters. Compilers translate source code written in a programming language into the language which a computer understands (mostly the binary form).…
