Parts of a Computer and Their Functions

Orders delivered to U. Learn more. A modern PC is both simple and complicated. It is simple in the sense that over the years, many of the components used to construct a system have become integrated with other components into fewer and fewer actual parts. It is complicated in the sense that each part in a modern system performs many more functions than did the same types of parts in older systems.

This section briefly examines all the components and peripherals in a modern PC system. Each item is discussed further in later chapters. The motherboard is the core of the system.

It really is the PC; everything else is connected to it, and it controls everything in the system. Microprocessors are covered in detail in Chapter 3, "Microprocessor Types and Specifications.

The processor is often thought of as the "engine" of the computer. It's also called the CPU central processing unit. The system memory is often called RAM for random access memory. This is the primary memory, which holds all the programs and data the processor is using at a given time.

Memory is covered in detail in Chapter 6, "Memory. The case is the frame or chassis that houses the motherboard, power supply, disk drives, adapter cards, and any other physical components in the system. The power supply is what feeds electrical power to every single part in the PC. The power supply is covered in detail in Chapter The floppy drive is a simple, inexpensive, low-capacity, removable-media, magnetic storage device.

The hard disk is the primary archival storage memory for the system. Hard disk drives are also covered in detail in Chapter 10, "Hard Disk Storage. These drives are covered in detail in Chapter 13, "Optical Storage.

The keyboard is the primary device on a PC that is used by a human to communicate with and control a system. Keyboards are covered in detail in Chapter 18, "Input Devices.

Although many types of pointing devices are on the market today, the first and most popular device for this purpose is the mouse. The mouse and other pointing devices are covered in detail in Chapter The video card controls the information you see on the monitor. Video cards are covered in detail in Chapter 15, "Video Hardware. It enables the PC to generate complex sounds.

Sound cards and speakers are covered in detail in Chapter 16, "Audio Hardware. Most prebuilt PCs ship with a modem generally an internal modem. Modems and other Internet-connectivity devices and methods are covered in Chapter 19, "Internet Connectivity.

Computer hardware for business

Hardware refers to the physical elements of a computer. This is also sometime called the machinery or the equipment of the computer. Examples of hardware in a computer are the keyboard, the monitor, the mouse and the central processing unit. However, most of a computer's hardware cannot be seen; in other words, it is not an external element of the computer, but rather an internal one, surrounded by the computer's casing tower. A computer's hardware is comprised of many different parts, but perhaps the most important of these is the motherboard. The motherboard is made up of even more parts that power and control the computer. In contrast to software, hardware is a physical entity.


A computer system is made up of a combination of hardware and software. Hardware: power to the different components on the motherboard. 4 Primary IDE.


2.3. Introduction to Computers

Hardware refers to the physical, tangible computer equipment and devices, which provide support for major functions such as input, processing internal storage, computation and control , output, secondary storage for data and programs , and communication. A computer system is a set of integrated devices that input, output, process, and store data and information. Computer systems are currently built around at least one digital processing device. There are five main hardware components in a computer system: Input, Processing, Storage, Output and Communication devices. Are devices used for entering data or instructions to the central processing unit.

A computer is a machine that can be programmed to manipulate symbols. Its principal characteristics are:. Therefore computers can perform complex and repetitive procedures quickly, precisely and reliably. Modern computers are electronic and digital. The actual machinery wires, transistors, and circuits is called hardware; the instructions and data are called software.

For its part, the processor is the"brain"of the computer, responsible for retrieving, decoding, executing and rewrite the commands of the computer. Following table describes functions of laptop parts. The motherboard is an important computer component because it's what everything else connects to! First we'll have to figure out if a desktop or a laptop is going to be best for you.

A computer is any machine that can be programmed to carry out a set of algorithms and arithmetic instructions. In terms of construction, each of these main components are attached to the motherboard and then put into a protective case—resembling the clean, polished look most of us are accustomed to seeing. Sure, most computers have their own distinct design - and different brands of hardware installed - but the components listed above are standard across all computers.

Going over the parts of a computer and their functions will help you understand all the vital components that make up a computer. Here is a complete list of all the common computer hardware components and common peripherals that get used with them. It is usually designed in such a manner to make fitting a motherboard, wiring, and drives as easy as possible. Some are designed so well that it is easy to make everything look tidy and presentable too. Cases come in all different shapes and sizes to accommodate various types of computer components and to satisfy the needs of the consumer.
