The Inventor
The first practical form of
random-access memory was the
Williams tube starting in 1947.

3.

What is a RAM
Random-access memory (RAM) is
a form of computer data storage.

4.

Today
Nowadays DRAM is most
popular module of RAM.

5.

Magnetic-core
Magnetic-core memory was invented in
1947 and developed up until the mid-1970s.

6.

In practice
System performance of the computer depends from RAM
not less than processor, especially if you work with
graphics, animation, video, or large amounts of text, or
play in the modern game.

7.

Manufactorers
When selecting the RAM first you need to
pay attention to the manufacturer such as
Samsung, Kingston, Corsair and others.

8.

Types
The two main forms of modern RAM are static
RAM (SRAM) and dynamic RAM (DRAM).

9.

EEPROM
Both static and dynamic RAM are considered volatile, as their
state is lost or reset when power is removed from the system.

10.

Virtual memory
Method for managing computer memory that allows you to
run programs that require more RAM than your computer
has, by automatically moving the parts of the program
between main memory and secondary storage (e.g. hard disk)

11.

BIOS and Drivers
By the way the main code BIOS is contained in the ROM chip
on the motherboard. Other essential and drivers are in the
ROM chip to be loaded during system startup, and the other
drivers on hard drive which is not particularly important.
