COMPUTER APPRECIATION PART III: PARTS OF THE COMPUTER AND FUNCTIONS

 PART OF THE COMPUTER AND THEIR USES

Welcome to the part 3 of Computer appreciation class. We shall be focusing on the various parts of the computer. before we begin, i will like to remind you that  study and read hard to prepare you for the general assessment coming up after the computer appreciation class.

Now, what are the part of computer.

1. The CPU

The Central Processing Unit (CPU) is the part of computer which handles most of the computer's calculations, Generally speaking, a faster CPU means more calculations in a shorter period of time, and therefore a faster machine.I CONSIDER THE CPU to be the BRAIN of the computer

2. Motherboard and Ports

i consider the motherboard to be the heart of the computer. The motherboard acts as the backbone to the system, connecting components such as the CPU and RAM modules together and managing communications between them. The type of motherboard also determines the number and type of available ports, such as a HDMI output or a USB input. The motherboard is responsible for handling input and output signals, as well as transferring data to and from the installed disk drives. The motherboard and the system itself are powered by a Power Supply Unit (PSU) that draws power from the mains or (in the case of a laptop) the installed battery.

3. Hard Disks and Optical Drives

Hard disk drives store all of a computer's data, including personal files, applications and the operating system. Hard disks are sometimes used as overflow for temporary data when the RAM modules are full, but they operate much more slowly. Many systems now make use of the faster Solid State Drives (SSDs) rather than traditional hard disks, but the principles are the same — the drive is used to store all of the data held by the computer. Optical disc drives are also installed on some systems to read and write CDs, DVDs and Blu-ray discs.

4. Memory

The computer uses random access memory, or RAM, as a high-speed working storage space for programs, documents and the intermediate results of calculations. More RAM means more files and programs can be open and running at the same time without the machine grinding to a halt.

5. Monitor

A desktop computer isn't useful unless it gives you results; a monitor displays the results of the work done by the microprocessor and other parts. The display screen consists of thousands of small dots, called pixels, arranged in a rectangular grid. 

6. Keyboard and Mouse

The keyboard and mouse are the two most common input devices.  The keyboard is the finger of the computer while the mouse is the hands of the computer. The computer performs different actions depending on the icons you click and commands you type. The computer gives you nearly instant feedback, moving a pointer on the screen as you move the mouse and displaying characters as you type. 

7. Sound Card

The co mputer's sound card performs a similar function as the display, though it can input audio as well asproduce sound. The computer stores representations of sound as long strings of numbers; a graph of the numbers would resemble sound waves. 

8. Video Cards (Graphic Cards)

A Simple Graphics Card
A graphic card is the component of your computer that interprets video signal. These cards are necessary so that you can connect a monitor to your computer. There are many types of graphic cards available: anything from high-end gaming cards to TV tuner cards. Some popular graphic card manufacturers are NVIDIA, ATI, and EVGA.

9. Printers

A printer is used to print documents, photos, and anything else that appears on your screen. There are many types of printers, including inkjet, laser, and photo printers. There are even all-in-one printers, which can also scan and copy documents.

10. Speakers/headphones

Speakers and headphones are output devices, which means they send information from the computer to the user—in this case, they allow you to hear sound and music. Depending on the model, they may connect to the audio port or the USB port. Some monitors also have built-in speakers. I consider them to be the voice of the computer.

11. Network card

The network card allows your computer to communicate over a network and access the Internet. It can either connect with an Ethernet cable or through a wireless connection (often called Wi-Fi). Many motherboards have built-in network connections, and a network card can also be added to an expansion slot.

I hope you have learnt something from today's class. In a clean A4 paper write what you have learnt from today's class, you can type your questions and send it to this mail: ilciempowernment@gmail.com or chinonsonwakaeme@gmail.com

Have a nice day.
