Computer Fundamental

Computer Fundamentals is to know about Computer and also its Functions from starter to advance level. Simply a Computer is made/composed of hardware and software, and can exist in a variety of sizes and configurations. The software is the instructions that makes the computer work.

Components Of Computer

There are two types of components are used in a Computer System. and those are as follows:

+  Hardware

+  Software

+  Hardware

The term Hardware’s of a Computer refers to the physical components of your computer. Here are five parts of computer Hardware that can be found in most computer systems, from smart phones to desktop computers are as follows:

+  Processor: A processor/microprocessor is a small chip that resides in computers and other electronic devices. Its basic job is to receive input and provide the appropriate output.

+  Primary Storage: A primary storage is a medium that holds memory for short periods of time while a computer is running. RAM (Random Access Memory) and Cache are both examples of a primary storage device.

+  Secondary Storage: It is a non-volatile device that holds data until it is deleted or overwritten. Secondary storage is about two orders of magnitude cheaper than primary storage. It is also known as external memory, secondary memory and auxiliary storage.

+  Input Devices: An input device is a piece of computer hardware equipment used to provide data and control signals to Computer data processing system by user.

+  Output Devices: An output device is any device used to display computer system processed result/data to user by form of visual, soft copy or a hard copy.

+  Software

A Software is a set of instructions and its documentations that tells a computer what to do or how to perform a task in a Computer System. Computer use two types of software and those are as follows:

+  System Software: System software is a type of computer program that is designed to run a computer’s hardware and application programs. Examples of system software include operating systems like macOS, GNU/Linux and Microsoft Windows, computational science software, game engines, industrial automation, and software as a service applications.

+  Application Software: An application is a set of programs, that is designed for the end user. Examples of Applications software are database programs, word processors, Web browsers and spreadsheets.

In this course, we are later briefly discussing all about above.
