Computer memory is quite like Human memory. Demonstration for how the brain is like a computer.
Some scientists use computers to simulate how a brain might work. Instead of focusing on the chemical aspects of memory, they simulate the neural connections made in the processing of information.
Computer
memory 
can be any device, such as a silicon chip or a hard disk, used to store information.
In computers of the past, vacuum tubes, cores
and drums have been used. Today, computer chips are used.
Of course, computers' memory capabilities are increasing as technology advances. Computer chips' capabilities have expanded. Other computer memory devices include CD-ROMs, floppy disks, tapes, zip drives, DVDs, etc.
Virtually all computers
today have more than one level of memory. Its main storage, or random
access memory
(RAM) is fast, but limited in size. RAM is memory in the computer that can be
changed, or updated as needed. It functions very much like working memory in
humans. (Rupp, 1998, p. 62) The secondary storage is usually a hard disk. It
is usually much larger, but not as fast as the RAM. (Kurland and Lupoff, 1999,
p. 44-49)
