The main function and basic function of computer memory is
to store all data in the computer be it a file, image, photo, video, music and
so forth. Depending on the type of data, in addition to storing data, computer
memory can perform several other functions as well. All functions related to
this digital storage, such as RAM, ROM, data storage, hard drive, solid state
drive, and flash memory. Each of these memory performs the functions necessary
to keep the computer working properly without any constraints.
The functions are as follows.
- RAM
RAM (Random Access Memory) is a computer hardware that has a
function for data storage and an instruction - instruction program that we are
running and previously executed by a Processor. While the storage properties in
RAM is temporary, in a broad sense when we are still doing a process on a
computer, the data we run for a while in the save on RAM but if the computer
has been turned off then the data stored in the RAM will automatically
disappear and if it will do the storage of a data, then the data will be stored
on the Hard Disk, where the hard disk is a computer hardware that functioned as
the main storage media (permanent).
- Hard Drive
Harddisk is one of the computer hardware that provides
storage space used to store or read data on the computer. Harddisk is a type of
computer memory that has non-volatile memory properties, which means data on
this type of memory will not be lost even if the device has been turned off.
Unlike RAM storage media that only store data as long as the device has power.
Harddisk comes with a variety of capacity sizes capable of
storing up to billions of bytes. Usually the larger the capacity of a hard
disk, the lower the RPM speed (rotate per minute). RPM here refers to the
rotational speed in a period of one minute performed by one of the hard disk
components called the platter. Each hard drive has a different rotation speed
depending on the type of harddisk, but the speed that is widely used today is
5400 rpm.
What is Flash Memory? How does it work? - Imagine if your
brain works only when you're awake. Every morning when you wake up, your mind
will be completely empty! You have to relearn everything you ever knew before
you could do anything. Sounds like a nightmare, but it's exactly like the
"problem" that the computer has.
Ordinary computer chips "forget" everything (loses
all of its contents) when power is turned off. This chip is usually called RAM
(Random Access Memory). In addition to RAM, the PC now also has other storage
memory that will keep any data even if the computer is turned off. This memory
is commonly called a hard drive or hard disk installed on the CPU.
- ROM
ROM stands for 'Read Only Memory' which is a hardware on a
computer or PC in the form of semiconductor memory chip whose contents can only
be read only. ROM can not be classified as RAM (Random Access Memory), although
both have similarities that can be accessed randomly or randomly. ROM (Read Only
Memory) is different from RAM (Random Access Memory).
Or bias also the definition of ROM is one of the memories
contained in the computer. This ROM has permanent properties, which means the
program or data stored in the ROM is not easy to lose or change even though the
power supply has been turned off. Storing data in ROM can not be done easily,
but reading the data can be done easily. Usually the program or the existing
data is filled by the factory that made it. Therefore these properties,
commonly used to store firmware (software that is closely related to hardware).
