Identify Computer Memory Types
Different computer memoryis designed to store data to be executed by the computer.
There are the read-only memory or ROM and the random-access memory commonly known as RAM.
If the ROM holds instructions for starting up the computer, the RAM is used in other context. Let’s see the
next!
The RAM or main memory permits you to read and write data but temporarily. That means as soon as you turned off your
computer, you loose whatever data stored in RAM. So why do you need a memory for?
Even if the RAM is a volatile storage
area, it is where the CPU has direct access to the program to be executed. You understand that this component is not only important but
necessary.
Now let’s learn more about it to better
identify each type!
Different computer memory types: Different computer memory has been created to hold data. Beside the Extended Data
Out -EDO(effective for a bus speed up to 66 MHz – found in old computers, there are three basic types RAM
memory:
-
the Synchronous Dynamic Random Access Memory, SDRAM, effective for a
bus speed of up to 100 MHz or 133 MHz;
-
the SDRAM Double Data Rate -SDRAM-DDR, effective for a bus speed up to
266 MHz;
-
the Rambus DRAM -RDRAM faster than the SDRAM-DDR and running up to 800
MHZ.
However, the speed is not the only
considerations to look for when purchasing computer memory. Assess equally the format and the size.
Different computer memory format. Whatever the computer memory types you plan to choose it can be materialized
differently. Three formats (or types of circuit board to hold memory chips) are presently the most known an available:
-
the Single In-line Memory Module or SIMM format commonly used in pair on
Pentium motherboards to fill a memory bank;
-
the Dual In-line Memory Module or DIMM format used singly on Pentium
motherboards and capable to handle the work of two SIMMS (the meaning of dual). It is economical and actually most
predominant;
-
the Rambus In-line Memory Module or RIMM format, faster but much expensive
than the others.
Different computer memory size.
Now you know what to choose, let’s see the capacity suitable that you can estimate.
If you remember it, RAM is a storage area of data used by the CPU to perform the tasks by the programs. The size is measured in MB
and could be:
-
16 MB or 32 MB more and more unused;
-
64 MB minimum required to run old
PC;
-
128 MB minimum required to run new
PC;
-
256 MB minimum recommended
actually;
-
512 MB for a faster PC;
-
1 GB to really enjoy
yourself.
Notice 1: Do not exceed the
maximum amount of memory specified to be added to your computer. This amount is indicated in the motherboard user’s manual.
Notice 2: Verify first the instructions in this manual before purchasing. Let’s see this example found in a
manual;
The mainboard accommodates SDRAM up to 1 GB using two 3.3 V unbuffered DIMM modules.
SDRAM is the type of memory, DIMM is the format or module (in this case the motherboard can receive two 512 MB of 3.3 V of current
each), 1 GB is the maximum size (meaning you can use from 256 MB to 1 GB).
Reading the instruction in your motherboard manual is the best way to buy Different computer memory.
