IDENTIFY TYPES OF COMPUTER MEMORY

There are many types of computer memory. If you want to upgrade your computer memory, you have to know the different types of memory.
Computer memory is an internal storage area that stores data permanently or temporarily.
It also affects the speed by which the computer processes the data.
Modern computer has a combination of memory,and not just one type.
Computer memory has four basic types.These are
**Cache
**RAM
**Virtual
**Hard Drive
Hard Drive memory is where you permanently store your data. It contains program files, permanent files, Internet files and files that are saved by the user. The capacity of the Hard Drive memory is measured by gigabytes.
The Hard Drive memory capacity of old computers or laptops starts from 20gigabytes (20GB).
Nowadays,most computers come with 360gigabytes or higher.

Virtual memory plays its role when running applications that are too large to handle by Random Access Memory(RAM).
To temporarily store data,the computer’s Operating System uses the Hard Drive and gives it back when needed. Virtual memory’s usage of Hard Drive slows down the performance of the computer.

Cache memory stores the most frequently used processes of the computer. It has 3 grades to indicate its level. Level 1 and 2 are the most common Cache used in most computers and laptop.
Level 3 Cache indicates advanced level of systems.
Level 1 Cache memory is used for most frequently used information and processes. It is the primary memory used by the processor.
Level2 is next in line. It is more commonly used on the motherboard. Depending on the motherboard used in the computer,the Level2 can be upgraded or not.
Level is the most advanced Cache memory as it can speed up the memory.
The RAM or Random Access Memory is the most commonly used memory as every file or application that is processed in your memory needs it. Each time a data or application is requested on your computer,the processor sends the request to your RAM,which then processes and writes it back to RAM.
