Introduction

The basic parts of a desktop computer are the computer case,monitor, keyboard, mouse, and power cord. Each part plays animportant role whenever you use a computer.

It implies structure and order. It is the arrangement of components that helps to achieve objectives. Interaction: It refers to the manner in which each component functions with other components of the system. Interdependence: It means that parts of the organization or computer system depend on one another.

Structure of a computer. There are four main structural components of a computer – Central processing unit (CPU) or the processor: Controls the operation of the computer and performs its data processing functions. – Main memory: Stores data. – I/O: Moves data between the computer and its external environment. – System interconnection: Some mechanism that provides for communication. The history of computer development is a computer science topic that is often used to reference the different generations of computing devices. Each one of the five generations of computers is characterized by a major technological development that fundamentally changed the way computers operate.

Watch the video to learn about the basic parts of a desktop computer.

Computer Case

A computer case

The computer case is the metal and plastic box that contains the main components of the computer. It houses the motherboard, central processing unit (CPU), the power supply, and more.

Computer cases come in different shapes and sizes. A desktop case lies flat on a desk, and the monitor usually sits on top of it. A tower case is tall and sits next to the monitor or on the floor. The front of the case usually has an on/off switchand one or more optical drives.

Most of the personal computers you can purchase today include tower cases Loudness radar premiere pro cc 3000. Konica minolta c203 driver windows 7 64 bit. , rather than desktop cases; however, some computers are being made with all of the internal components built into the monitor, which completely eliminates the tower.

Monitor

The monitor works with a video card, located inside the computer case, to display images and text on the screen. Newer monitors usually have LCD (liquid crystal display) or LED (light-emitting diode) displays. These can be made very thin, and they are often called flat panel displays. Older monitors use CRT (cathode ray tube) displays. CRT monitors are much bigger and heavier, and they take up more desk space.

Most monitors have control buttons Virtual dj songs. that allow you to change your monitor's display settings, and some monitors also have built-in speakers.

LED displays are actually LCD displays that are backlit with light-emitting diodes. This allows for greater contrast than a traditional LCD display.

Power Cord

A power cord connected to a surge protector

The power cord is the link between the power outlet and thepower supply unit in the computer casing. If the power cord is not plugged in, the computer will not power on. To protect your computer from voltage spikes, you can plug the power cord into asurge protector. You can also use an Uninterruptable Power Supply (UPS), which acts as a surge protector and also provides temporary power if there is a blackout.

Keyboard

The keyboard is one of the primary ways we communicate with the computer and enter data. There are many different types of computer keyboards such as wired, wireless, ergonomic, multimedia, and more. Although there may be differences in the location of some keys or features, keyboards are very similar and allow you to accomplish basically the same tasks.

Mouse

The mouse is a peripheral that is known as a pointing device. It lets you point to objects on the screen, click on them, andmove them.

There are two main types of mice: optical and mechanical. Theoptical mouse uses an electronic eye to detect movement and is easier to clean. The mechanical mouse uses a rolling ball to detect movement. Generally, a mechanical mouse is cheaper, although it may require regular cleaning to keep it working properly.

Traditionally, a mouse connects to the computer using a USB orPS/2 connection. However, you can also buy a wireless mouse, which can reduce clutter on your desktop.

Mouse Alternatives

There are other devices that can do the same thing a mouse can do, but with a different look and feel. Many people find them to be easier to use, and they also require less desk space than a mouse. The most common mouse alternatives include:

A touchpad on a laptop

Trackball: A trackball has a ball on top that can rotate freely. Instead of moving the device like a mouse, you can simply roll the ball with your fingers to move the pointer. Some mobile devices have miniature trackballs that can be controlled with your thumb.
Touchpad: A touchpad (also called a trackpad) is a touch-sensitive pad that lets you control the pointer by making a 'drawing' motion with your finger. Touchpads are very common on laptop computers.

Computer: A computer is a combination of hardware and software resources which integrate together and provides various functionalities to the user. Hardware are the physical components of a computer like the processor, memory devices, monitor, keyboard etc. while software is the set of programs or instructions that are required by the hardware resources to function properly.
There are a few basic components that aids the working-cycle of a computer i.e. the Input- Process- Output Cycle and these are called as the functional components of a computer. It needs certain input, processes that input and produces the desired output. The input unit takes the input, the central processing unit does the processing of data and the output unit produces the output. The memory unit holds the data and instructions during the processing.

Digital Computer: A digital computer can be defined as a programmable machine which reads the binary data passed as instructions, processes this binary data, and displays a calculated digital output. Therefore, Digital computers are those that work on the digital data.
