PC hardware, such as a desktop computer, is the most common type of IT hardware purchased by a small business.
Here, we bring a computer hardware chart for an in-depth view of what your computer is all about. The arrows show the direction of data flow. Download as PDF for revision later. Viable Computer. It also includes all the parts inside the computer case, such as the hard disk drive, motherboard, video card, and many others.

Computer Awareness is tested in almost every exam. One of the oft seen topics in Computers is Hardware. Basic Computer Hardware questions are easy to remember and can count for easy marks. Download as PDF for revision later. Every part of your computer is the result of years of research and development. Parts that were once hand made at a cost of thousands of man-hours are now mass produced for a fraction of a rupee. Computer parts can be divided into two groups, hardware and software.
A peripheral device is generally defined as any auxiliary device such as a computer mouse or keyboard, that connects to and works with the computer in some way. RAM—random access memory—straddles the line between peripheral and primary component; it is technically a storage peripheral, but is required for every major function of a modern computer and removing the RAM will effectively disable any modern machine. Many new devices such as digital watches, smartphones and tablet computers have interfaces which allow them to be used as a peripheral by a full computer, though they are not host-dependent as other peripheral devices are. According to the most technical definition, the only pieces of a computer not considered to be peripherals are the central processing unit, power supply, motherboard, and computer case. Usually, the word peripheral is used to refer to a device external to the computer case, like a scanner, but the devices located inside the computer case are also technically peripherals.
INTRODUCTION TO COMPUTER HARDWARE
Generally, hardware and software optimization can improve PC maintenance in different degree. One way or the other, it is bound to happen. A com- This is the most important piece of work in preventive maintenance. It is not suitable for provision of services to a consumer, i. A preventive maintenance plan is developed based on the needs of the equipment. Computer Hardware 2. Cleaning the computer, keeping its fans free from dust, and defragmenting its hard drives regularly are all parts of a computer hardware maintenance … Hardware without a set of programs to operate upon cannot be utilized and is useless.
Computer hardware includes the physical parts of a computer , such as the case ,  central processing unit CPU , monitor , mouse , keyboard , computer data storage , graphics card , sound card , speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware. Hardware is so-termed because it is " hard " or rigid with respect to changes, whereas software is "soft" because it is easy to change. Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware. The template for all modern computers is the Von Neumann architecture , detailed in a paper by Hungarian mathematician John von Neumann.
External devices which are attached to the external part of the computer Any device connected internally or externally to a computer and used in the transfer of data Any input, output or storage device connected externally or internally to the computer's CPU, such as a monitor, keyboard, printer, disk, tape, graphics tablet, scanner, joy stick, paddle or mouse. Every peripheral device needs device driver to communicate with the computer system. An input device is any device that provides input to a computer. There are many input devices, but the two most common ones are a keyboard and mouse. The computer key board is used to input, or enter, letters, numbers, symbols, punctuations and commands into the computer.

This is an overview of Computer Peripherals PDF, if you want to read full article in best quality in pdf, we have provided download link below. The computer peripherals are devices. We connect the peripheral devices externally to the computer but actually not part of the computer system. The best examples for peripherals devices are the printer, monitor, keyboard, touchpad, joystick, and many more. These are not the core elements in computer architecture.
We have included this unit to help those who are teaching students with no computer background. Hardware The physical parts of a computer system. Hardware and Software Computer hardware is the collection of physical elements that constitute a computer system. Summary This chapter discussed the concepts of preventive maintenance and the troubleshooting process.
