- CPU (Central Processing Unit) - is the abbreviation for central processing unit. It is most important part of the computer, the brain of the computer,
- Motherboard - The main circuit board of a microcomputer. The motherboard contains the connectors for attaching additional boards.
- RAM (Random Access Memory) - allows data items to be read and written in roughly the same amount of time regardless of the order in which data items are accessed.
- ROM (Read Only Memory) - is computer memory on which data has been prerecorded. It retains its contents even when the computer is turned off.
- Hard Disk Drive - mechanism that reads and writes data on the hard drive. They give computers the ability to remember things when the power goes out.
- Video Graphics Card - allows a display device such as a monitor to display images from the computer.
- GPU (Graphics Processing Unit) - is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display.
- Sound Card - is an expansion card or integrated circuit that provides a computer with the ability to producesounds that can be heard by the user either over speakers or headphones.
- Video Monitor - A display screen that you can see what you doing.
- Keyboard and Mouse - To control your what you are doing on the the computer. Keyboard is to type letters on the computer & Mouse is to select what you want to run
- Network Card - To recognize your wired network and give your computer ability to use internet.
- CD ROM \ DVD ROM - A CD-ROM is an optical disc which contains audio or software data whose memory is read only. A CD-ROM Drive or optical drive is the device used to read them.
- CD RW \ DVD RW - Disc that you put in the CD ROM/ DVD ROM,
- USB Card (Universal Serial Bus) - Allows to use USB devices.
- PCI Expansion Port - Allows additional boards to be connected to it.
- Flash Memory - Is an electronic non-volatile computer storage medium that can be electrically erased and reprogrammed.
- Power Supply Unit & Fan - PSU Converts mains AC to low-voltage regulated DC power for the internal components of a computer. Fan is to cool off you computer from heating.
- Case - To protect the computer parts and helps organize the chips.
1. What is the difference between RAM and ROM?
RAM is the fastest memory chip on the computer, it can the data fast but it will be lost the power is off. ROM chip will keep the information stored on it, when the power is lost or turned off.
2. What is the difference between a DVD ROM and a DVD RW?
DVD RW is a disc you insert in to the DVD ROM and allows the DVD ROM to read it.
3. What are some advantages to using the USB system of connecting peripheral devices?
It is easy to carry on you, anytime and anytime, and you can transfer documents, videos, pictures computer easily.
4. Why would you want a GPU (graphics processing unit) when playing video games on your computer?
So it won't froze your computer by playing a game.
5. How does a hard drive (sometimes called hard disk) store information? What is the current typical size of an average hard drive?
There's just a large shiny, circular "plate" of magnetic material called a platter, divided into billions of tiny areas. Each one of those areas can be independently magnetized (to store a 1) or demagnetized (to store a 0). Magnetism is used in computer storage because it goes on storing information even when the power is switched off. Common sizes in terms of storage space would be, 700GB to 1TB, but this figure is constantly changing. Common sizes in terms of physical size would be 2.5", and 3.5" for PATA and SATA standards.
6. What is a floppy disk? How much data can it hold? Why are they almost completely obsolete today?
It's an old class disk, it can't hold much then 2 pages of words, most of the floppy disk can hold 1.44 mb less then a big picture.
7. What are the advantages of a Flash Memory device over a Magnetic Disk? What is one disadvantage?
It's faster, no over heating, no change in harming you content if you were to accidently hit it while saving or moving files. Disadvantage is if your lose or break your flash memory, your data will lose till your flash memory back (recommended to save your data in two different hard memory for you backup)
8. Which can transmit or receive the most data: copper wire, radio waves (wireless technology), or fiber optics (light)? What are some common units used to measure this speed?
Radio waves are the fastest to transmit or receive the most data, the units are:
Hz = hertz = 1 cycle/second
KHz = kilohertz = thousand (1,000) cycles/second
MHz = megahertz = million (1,000,000) cycles/second
GHz = gigahertz = a thousand million (1,000,000,000) cycles/second
