Full information about computer storage devices
Full information about computer storage devices
Hello again my friends the last lesson we talk about Ram, ROM and cached memory .This lesson we will talk about storage devices in computer. Lets start now.
Storage Devices
The volumes are the units that can keep your data and programs and those units are divided into: solid cylinders, and floppy discs, CDs (laser CDs), and the multifaceted digital roller, and the magnetic strip, and flash memory.
Hard Disks
A small unit in the size of the palm of the hand almost always exist in and installed in the central processing unit (CPU) and the cylinder characterized by sizable storage capacity as they reach the storage capacity to store more than ten thousand books any nearly ten billion character.
Floppy Disks
There are two types 3.5-inch floppy discs are now used in the process of saving data view of their small size and the large size of the storage capacity flexible cylinders 5.25 is no longer used now concision consider the small size of the amplitude storage and large size.
Compact Disks (CD)
CDs or laser discs are the latest means of storage where they are used to store audio and video clips, where storage capacity of up to 650 six hundred and fifty million characters. The disadvantage of this quality that they can not register only once and only one.
DVD Digital Versatile Disk
It is a type of high-capacity CDs used to store 2.10 GB of information. And used compact disc (CD) to store music, usually used to store high-quality movies instead of video tapes
Magnetic Tape
This type of storage media similar to what we see in the world of audio cassettes magnetic audio recorder and based on the same technology information is stored in the form of magnetic points sequentially, and these strips are commonly used in save backups of data.
Flash Memory
Is a memory used to store data and is characterized by its small size and large storage capacity, where up to more than GB, can also scan data from them and write them more than once and is connected to the computer by USB.
After explaining parts Computer physical detail must clarify the relationship and the extent of interdependence of each part with the other to carry out operations required from the computer example for doing arithmetic what first must enter numbers by Input units are then processed by the control unit Central to get the results that are brought out of During the output units, and stored by the storage units and the following figure illustrates the interdependence of computer parts with each.
My friend now we finished the first part of computer components (Hardware Components) the next lesson we will talk about computer software part .To be continued .Thank you
