Classification Of Hardware | Types of computers hardware's

 Classification Of Hardware 🖥️ Computer hardware is the physical tangible part of a computer. They comprise the main part of a computer both internal and external or peripherals. The main characteristic of hardware is it can be seen, felt, and even touch, unlike computer software. The computer hardware is categorized into input, processing, storage, output, and communication devices. Each category is used for different functions. Input devices are used to enter data into the computer, then the processing component takes over to process it into information. During processing, it is stored in the main memory and secondary storage for future reference. To display the data being processed or results output devices are used, and it can be shared with help of communication components. Functions of computer hardware devices A computer is made up of many physical hardware components that are meant to achieve different functionality within the system. It should be noted that all hardw...

Components of a Computer System

Components of a Computer System A computer system consists of hardware, software, firmware and liveware. Hardware The hardware components of a computer are the physical components of the computer that you can touch. The monitor, system unit, keyboard, and mouse are the primary hardware components. Other peripherals include a webcam, router, external hard drive, printer, speaker and any other item that can be connected to the computer via cable or wirelessly. The system unit also includes some critical internal hardware components such as; Motherboard Disk Drive Random Access Memory (RAM) (RAM) CPU Graphics Card CD ROM Fan,etc. Software Software is a collection of programs or applications that contain the instructions that allow a computer to function. For example, when you type words on the keyboard, the software is in charge of displaying the correct letter in the correct location on the screen. Software is stored on your computer's hard drive.

Data Communication Media: An Overview

Data Communication Media: An Overview Data communication is the transfer of data, information, or messages from one place to another through various technologies. The transfer of data can take place through a variety of media, which can be broadly categorized into two types: guided and unguided. Guided Media Guided media, also known as wired media, refers to the transmission of data through physical cables or wires. The signals are guided along a specific path, and the data transmission is limited to the length of the cable. Guided media provides a more reliable and secure data transmission compared to unguided media, but it is also more expensive and less flexible. Examples of Guided Media Twisted-Pair Cable: Twisted-pair cable is a type of copper wire that is commonly used in local area networks (LANs) and telephone networks. It consists of two wires that are twisted together to reduce interference and improve signal quality . Coaxial Cable: Coaxial cable is a type of cable that is c...

Classification of Software

Classification Of Software⚙️ Software can be broadly classified into two main categories: system software and application software. System software: System software is a type of software that controls and manages the underlying hardware of a computer system. It includes the operating system, device drivers, firmware, and other software that is responsible for managing the computer's resources and providing an interface between the hardware and the user. Examples of system software include Windows, Linux, and macOS. Application software: Application software is a type of software that performs specific tasks or functions for the user. It is designed to be used by end-users to accomplish specific tasks, such as word processing, graphic design, video editing, and more. Examples of application software include Microsoft Word, Photoshop, and Final Cut Pro. System software System software is a type of software that controls and manages the underlying hardware of a computer system. It inc...
