RAM is a moniker for Random Access Memory. It acts as a short-term
memory much like the human brain to store a wealth of information. The
RAM is accessible through the computer's brain called the CPU which
stands for Central Processing Unit. RAM has the capability of being
retrieved only while a computer is on. When the computer is turned off
the RAM is no longer accessible. ROM chips along with BIOS (computer
boot firmware) allows the RAM information to be retrievable when the
computer is rebooted.
RAM size and Location on the Computer System
Most computers come equipped with 256 million bytes of RAM already on
the computer. Additional RAM can be placed within the system. However,
there is usually a limitation placed upon just how much RAM can be
added to a computer system. RAM is not random as its name would lead
one to believe. The RAM is highly controlled and the storage can be
directly ascertained. There is a decisive method that RAM utilizes to
make its memory available to certain areas of the computer system.
Forms for RAM
RAM is what is known as discrete microchips which means that it is
separate. An additional form of RAM is modules which attach into
outlets in the motherboard of the computer. A network of electrical
pathways to the processor allows the connection to spark for the RAM.
Why is RAM Important
RAM serves the very important function of retrieving information that
must be accessed in a quick manner. This operation is very similar to
the human brain's function in retrieving necessary facts from short
term memory. Open files and the utilization of applications on a
computer systems requires the assistance of RAM. Users that play alot
of video games with detailed graphics or keep alot of folders open
while on their computer, will need the use of additional RAM. This will
allow them to better access the information they need when the time
comes. RAM is held onto a limited time, but it allows the information
to come up quickly and without much fuss on the part of the computer
user.
