Five examples of storage devices

1. Random Access Memory

The Random Access Memory is used for storing information temporarily. When the computer is switched off, the information on the RAM is wiped off. The access rate of RAM is much higher. They are more expensive than the other types of primary storage devices.

                            

2. Read Only Memory
       It is used to permanently store data. Data can be stored on ROM, either      when the computer is been manufactured or by the computer user. However, the disadvantage of this type of memory is that the data stored on ROM cannot be changed. The access rate necessary to get to the memory is much lesser as compared to the access rate of the RAM. Unlike the RAM’s, ROM’s are not expensive.



                                                         

3. Hard Drives

    The hard drive are one of the most important of the secondary types of computer data storage device, the hard drive device Data is stored on the hard drives in the digital format on the hard drives. In the initial days of the computers, hard disks were like removable mass storage devices. However, with time they started coming as a part of the central processing unit of the computer. However, now there are external hard drive available as well.

4. Memory Cards
The next of the computer storage devices examples are the memory cards. Data is stored in digital format on the memory cards. They can be used in various electronic devices from hand held computers, mobile phones, cameras, etc. They are also rewritable. Although they are small in size, they can store a high amount of data.

 
5. Flash Memory
With a lot of research came the flash memory. This storage devices for a computer is similar to the read only memory. However, there is a big difference between the flash memory and the ROM. Data from the flash memory can be erased in a matter of few seconds from the flash drives, which is not the case with the ROM’s. At the same time, the data can be changed as per the requirement.
