STORAGE DEVICES

Alternatively referred to as storage, storage media, or storage medium, a storage device is a hardware device capable of holding information. There are two storage devices used in computers; a primary storage device such as computer RAM and a secondary storage device such as a computer hard drive. The secondary storage could be a removable, internal, or external storage. In the picture to the right, is an example of a Drobo, an external secondary storage device.
Without a storage device, you and your computer would not be able to save any settings or information and would be considered a dumb terminal. Below, are some additional examples of storage devices that are used with computers.

TYPES OF STORAGE

OUTPUT DEVICE

Any peripheral that receives or displays output from a computer. In the picture to the right, is an inkjet printer and a good example of an output device that can make a hard copy of anything on a computer. Below is a listing of all the different computer output devices found on a computer.

PROCESSOR

The processor (called CPU, for Central Processing Unit) is an electronic circuit that operates at the speed of an internal clock thanks to a quartz crystal that, when subjected to an electrical currant, send pulses, called "peaks". The clock speed (also called cycle), corresponds to the number of pulses per second, written in Hertz (Hz). Thus, a 200 MHz computer has a clock that sends 200,000,000 pulses per second. Clock frequency is generally a multiple of the system frequency (FSB, Front-Side Bus), meaning a multiple of the motherboard frequency.

With each clock peak, the processor performs an action that corresponds to an instruction or a part thereof. A measure called CPI (Cycles Per Instruction) gives a representation of the average number of clock cycles required for a microprocessor to execute an instruction. A microprocessorâ€(TM)s power can thus be characterized by the number of instructions per second that it is capable of processing. MIPS (millions of instructions per second) is the unit used and corresponds to the processor frequency divided by the CPI.
