It holds together many of the crucial components of a computer, including the central processing unit (CPU), memory and connectors for input and output devices.]]> 2017-01-10 13:01:53 UTC https://padlet.com/s1001062/jwq1gr3sxrxo/wish/146227341 RAM s1001062 https://padlet.com/s1001062/jwq1gr3sxrxo/wish/146227531 RAM is considered volatile memory, which means that the stored information is lost when there is no power. So, RAM is used by the central processing unit (CPU) when a computer is running to store information that needs to be used very quickly, but it does not store any information permanently.]]> 2017-01-10 13:02:54 UTC https://padlet.com/s1001062/jwq1gr3sxrxo/wish/146227531 System fan s1001062 https://padlet.com/s1001062/jwq1gr3sxrxo/wish/146227812 A computer fan is any fan inside, or attached to, a computer case used for active cooling, and may refer to fans that draw cooler air into the case from the outside, expel warm air from inside, or move air across a heat sink to cool a particular component.]]> 2017-01-10 13:04:25 UTC https://padlet.com/s1001062/jwq1gr3sxrxo/wish/146227812 Hard disk s1001062 https://padlet.com/s1001062/jwq1gr3sxrxo/wish/146228390 Hard Disk Drives (HDD) Hard disk drives have been the dominant type of storage since the early days of computers. A hard disk drive consists of a rigid disc made with non-magnetic material, which is coated with a thin layer of magnetic material. Data is stored by magnetizing this thin film

It’s an electromechanical device that reads and writes floppy disks. A computer program may give an instruction to the hardware so that a data file is written onto a floppy disk. Floppy drives do data transfer, small file storage and backup, and it’s used for software installation and driver updates.
