  1. 2. state Is a type of computer storage media that stores data electronically and has no moving parts. it is made from silicon microchips. Because there are no moving parts, it requires less power and produce far less heat than spinning hard disk drives or magnetic tape.
  2. 5. Is a thin fibre of glass or plastic that can carry light from one end to the other. Its transmission speeds are faster than copper cables and can carry a signal further.
  3. 7. This type of storage is one of the most affordable ways to store large amounts of data. It uses the two types of magnetic polarities to represent the binary information consisting of zeros and ones. Commonly used devices that use magnetic storage include floppy disks and hard-disk drives.
  4. 8. Made from copper it lets you physically connect your computer to the internet. These connections are almost always faster than Wi-Fi connections, and are usually more stable. You'll need to connect one end of the cable to your router, and the other to your computer.
  5. 9. Is the brain of the computer. It controls all the functions of the computer. Its job is to listen for input data from devices like a mouse or other software. Then it looks up instructions for that data, and executes those instructions.
  6. 10. It holds the data and instructions that the Central Processing Unit (CPU) needs. Before a program can be run, the program is loaded from some storage medium into the memory. This allows the CPU direct access to the program.

  1. 1. is a wireless communication over short distances. Devices such as mobile phones, laptops, PCs, printers, digital cameras and video game consoles can connect to each other, and exchange information. This is done using radio waves. Is usually only used for relatively short distances, like 10metres.
  2. 3. The main circuit board that holds the principal components in a computer system
  3. 4. The wireless networking technology which uses radio waves to transmit data at high speeds over short distances. Often used in local area networks (LANs), computer networks that link computers and devices over small geographic areas.
  4. 6. This type of storage uses lasers to read and write data to a disc. The CD or DVD disk is similar to a mirror and the laser light reflects off it. The disk has very small (microscopic) codes written on it.
