RAM stands for random access memory and is used as temporary storage for data retrieved from the hard drive. The first modern form of RAM was released in 1969 by Intel, which created the 64-bit 3101 Shottky Bipolar memory. RAM has evolved significantly since then through improvements. Static RAM (SRAM) holds its data without refreshing as long as power is supplied, while dynamic RAM (DRAM) must be regularly refreshed to maintain data and is the most common type used in computers. Read-only memory (ROM) is programmed with fixed data during manufacturing and is used to store firmware for booting devices.

2. Introduction to RAM
RAM stands for “Random Access Memory” ,
RAM is used to quickly access
Data from your computers hard drive. When it
gets the data from the hard drive
It is temporarily stored as RAM. RAM is used
a temporary memory when programs/Files such
as Explorer is opened.

4. What’s the history of
RAM?
The first modernized form of RAM was released on 1969
and it was done by a company.That is pretty popular now,
This company is Intel. They created the 3101 Shottky
Bipolar memory,
This was a 64 bit static RAM. This was believed to be the
first successful product that intel released.
From this date and on RAM started to evolve into what it is
today, Through the years it got improvements
And eventually became what we see today.

8. Static RAM is a type of RAM that holds its data without external
refresh, for as long as power
Is supplied to the circuit. This is contrasted to dynamic RAM
(DRAM), Which must be refreshed many
Times per second in order to hold its data contents. SRAMs are
used for specific applications within the PC,
Where their strengths outweigh their weaknesses compared to
DRAM.
 Simplicity : SRAMs don’t require external refresh circuitry or
other work in order for them To keep their data intact.
Speed: SRAM is faster than DRAM
Compared to DRAM, SRAM is more power efficient when idle
SRAM is several times more expensive than DRAM.

9. Dynamic RAM is the standard computer memory of
vast majority of modern desktop computers.
It is a volatile memory that needs to be refreshed with
voltage regularly, otherwise it loses the information
stored on it.
Dynamic RAM is also referred to as DRAM. Volatile
means that it loses the information stored on it as
soon as power is withdrawn.

10. Introduction to ROM
Read-only memory (ROM), also known as firmware, is an
integrated circuit programmed with specific data when it is
manufactured. ROM chips are used not only in computers,
but in most other electronic items as well. In this section,
you will learn about the different types of ROM and how
each works. Rom is used for Computers, Mobile phone,
TV ,Etc.
BIOS setup is already installed in computers BIOS stores in
ROM (firmware)
