A computer is an electronic device that performs numerous procedures like programming, data storage, processing, and output data. It is a device that can do a mixture of activities by following instructions. It uses programs and apps to carry out tasks. A computer is fundamentally made up of hardware and software parts. Physical features such as the CPU, RAM, hard disk, SSD, input/output devices (keyboard, mouse, touchpad), speakers, monitor, printer, and USB/HDMI/Ethernet ports are all considered to be part of the hardware. Many of the 3rd grade students need to learn the basics of the computer as they have to complete the projects, so choosing the online computer science classes for class 3 is always a great option for them.

Parts of a Computer

The main components of computers are the keyboard, mouse, power cord, monitor, and computer casing. Every component has a crucial function whenever you use a computer. With the help of online coaching classes, Students can learn how to operate these devices properly; tutors will guide them on how to make presentations and worksheets on the computer. Let's understand these components in detail.

Monitor

Text and images are shown on the monitor's screen thanks to a video card that is housed inside the computer casing. In addition to some models having built-in speakers, most monitors contain control buttons that let you adjust the display settings. LED (light-emitting diode) or LCD (liquid crystal display) screens are common in more recent monitors. These are also known as flat panel displays since they may be manufactured extremely thin.

Keyboard

The keyboard looks like a typewriter. We use it to type words and numbers into the computer. One of the primary ways of interacting with a computer is through the keyboard. Although there are many types of keyboards, most are relatively similar and allow you to perform the same basic functions.

Mouse

Another important tool for interacting with computers is the mouse. This device, also referred to as a pointing device, allows you to move, click, and point at items on the screen. The two primary categories of mice are mechanical and optical. With its electronic eye for motion detection, the optical mouse is easier to maintain. The rolling ball that the mechanical mouse utilizes to catch movement needs to be cleaned regularly.
