Solid State Storage is computer storage media that stores data electronically and has no moving parts

18
Q

What is Cloud storage?

A

Cloud storage is a type of storage that lets you store data with multiple redundancy options, virtually anywhere

19
Q

What is Optical Storage?

A

Optical Storage is any storage type in which data is written and read with a laser

20
Q

What is Magnetic Storage?

A

Magnetic Storage is a storage of data on a magnetized medium (Floppy Disks, Hard Disks, Magnetic Tape).

21
Q

What is another name f or Storage Medium?

A

A storage medium is also called secondary storage.

22
Q

Define Storage Media?

A

Storage Media are the physical materials or components on which a computer keeps data, information and instructions.

23
Q

Which is Volatile, Rom or Ram?

A

RAM IS VOLATILE.

24
Q

What is another name for Primary storage?

A

Primary storage is also called main memory or immediate access store

25
Q

What are the types of ROM?

A

PROM, EPROM, EEPROM

26
Q

PROM

A

Programmable Read Only Memory. This is acquired as a blank chip. Once the PROM is
programmed, the information written is permanent and cannot be erased or deleted.

27
Q

EPROM

A

Erasable Programmable Read Only Memory. This is a type of ROM chip which can be erased and reprogrammed several times. It has to be removed from the computer to be reprogrammed.

28
Q

EEPROM

A

Electrically Erasable Programmable Read Only Memory. Similar to EPROM, but can be reprogrammed without removing it from the computer.
