Parts of a computer
Definitions :-
- CPU (Central Processing Unit) = It is basically like the brain of the computer.
- Motherboard = This is where the CPU is in the computer. It also holds things like memory. It is referred as the mother of every hardware of a computer.
- RAM (Random Access Memory) = A place where data is stored in the computer. It is used so people can access there data fast.It is a form of computer data storage. Data can be modified fast.
- ROM (Read-Only Memory) = A place where data is stored in the computer. Unlike RAM, data modification is slow in ROM.
- Hard-Disk Drive = It is where you can put a disc(CD) and use it. It is used to retrieve digital data from disc.
- Video Graphics Card = This thing is needed to display everything in your computer. It generates images as output
- GPU (Graphics Processing Unit) = It is needed for rendering images and other effects such as lighting in an image.
- Sound Card = Device used in computer to create sound for things like videos or games.
- Video Monitor = It is the display device on your computer. The thing which you use to see what you're doing on your computer. It is the screen you're currently looking at.
- Keyboard & mouse = Keyboard is the thing you use to type on the computer. It has all the letters on it but they are not arranged in the A-B-C order. Mouse is the thing you use to move around your screen display and be able to select things.
- Network Card = Used to connect your computer to anything specific such as internet. It is in every computer.
- CD ROM \ DVD ROM = It is a disc which we place in Hard Disk Drive. It is considered a ROM. It is used to retrieve digital data from.
- CD RW \ DVD RW = It is a storage thing made to store your disc at. Since your discs won't work if they get a scratch on them you got to make sure you do not do any physical damage to your CD. That is why it is suggested that you get a CD RW where you can place your disc at when you are not using them.
- USB Card (Universal Serial Bus) = Allows you to use USB devices. (Note:- USB is also called a PEN drive.)
- PCI Expansion Port = Sockets on your laptop or on your Computer's CPU where you can plug things like pen drive or headphones or an Ethernet wire or a cable wire.
- Flash Memory = The best way to explain this is using an example. For Example :- You're doing homework on your laptop and then the laptop indicates you're low on battery and you go to your room to get the battery charger but by the time you come back the laptop has run out of battery and you forgot to save your work! Well, no worries! Flash Memory has you covered. It retains all your data when you run out of battery on your laptop so you can resume your work.
- Power Supply Unit & Fan = Ever noticed how your laptop/CPU/Display Monitor start to heat up after using them for a little while? Computer uses electricity and so a lot of heat is made in that process. What Power Supply Unit does is, it has a fan on it which is used to throw away all the heat off your computer so it says cool.
- Case = The place that contains all the components of a computer. The box which a lot of people refer to as the CPU even though it is not the CPU but it contains the CPU. It basically contains all the parts of the computer which are used to run the it.
Questions & Answers :-
Q 1) What is the difference between RAM and ROM?
A 1) ROM is read only memory while RAM is memory stored in the computer for programs and processes to use at the moment.
Q 2) What is the difference between a DVD ROM and a DVD RW?
A 2) DVD ROM is read only. Meaning you cannot use DVD ROM to edit or put stuff in. DVD RW is re-writable. Meaning you can edit stuff in the DVD or put stuff in it.
Q 3) What are some advantages to using the USB system of connecting peripheral devices?
A 3) There are a lot of advantages of using a USB. It is portable meaning you can take it anywhere as it is small enough to be put in your pocket. It has a higher durability than a CD/DVD. Its memory capacity is pretty large when compared to something such as a DVD/CD. There are applications specifically made for the USB. It is very easy to use. It does not use computer energy to rotate a disk meaning it is energy sufficient.
Q 4) Why would you want a GPU (graphics processing unit) when playing video games on your computer?
A 4) It is very efficient at manipulating graphics in a computer. It increases the amount of FPS the application runs at. FPS(Frames per second).
Q 5) How does a hard drive (sometimes called hard disk) store information? What is the current typical size of an average hard drive?
A 5) Data is stored in the form of files. 1 - 48 GB.
Q 6) What is a floppy disk? How much data can it hold? Why are they almost completely obsolete today?
A 6) Floppy disk were used as a storage device for data. They could hold at the most 2 MB of data. They are obsolete today because of new technology and new ways of storing data such as CD/DVDs, USB flash drives etc.
Q 7) What are the advantages of a Flash Memory device over a Magnetic Disk?
A 7)
Q 8) Which can transmit or receive the most data: copper wire, radio waves (wireless technology), or fibre optics (light)? What are some common units used to measure this speed?
A 8) Radio Waves. Standing waves of UHF radio are used to measure the speed of radio waves, which is then compared with the measured speed of light.
