Memória RAM é um sistema de armazenamento de dados. RAM significa "Random Access Memory", Memória de Acesso Aleatório, em inglês, e esta nomenclatura se deve ao fato de que o sistema acessa dados armazenados de maneira não-sequencial, ao contrário de outros tipos de memória. A memória RAM é volátil, ou seja, não grava de modo permanente os dados nela contidos. Quando a alimentação do sistema é cortada, tudo que foi guardado é perdido.
Getting started with setting up embedded platform requires audience to understand some of the key aspects of Linux. This presentation deals with basics of Linux as an OS, Linux commands, vi editor, Shell features like redirection, pipes and shell scripting

Presentation on computer memory
1.
2. As the word implies “memory” means the place where
we have to store any thing, this is very essential part of
human being just like this memory is also very
important for computer system because in computer
system we have to store some data or information and
for storing these items we need some memory or
space.
So that’s why we can say that memory is very important
part of computer system.
3. There are various units which are used to measure
computer memory
Bit - Smallest unit of computer memory
Byte - 8 bit = 1 byte
Kilobyte - 1024 byte = 1 kb
Megabyte - 1024 kb = 1 mb
Gigabyte - 1024 mb = 1 gb
Terabyte - 1024 gb = 1 tb
4. 1. Primary Memory :-
Primary memory also known as “main memory”
or “internal memory” which is located in the mother
board of system or as we say which is directly
connected to the CPU. It is the place where only little
bit of data are stored either by manufacturer or by
user.
This is further divided into two parts :-
RAM
ROM
5. RAM also known as “random access memory” it stores
the data which the user currently uses or as we say it
stores the data temporary in it. RAM needs power or
electricity to work when the computer power is turned
off then all the data in it will be erased automatically.
This is a circuit which have its separate space or slot in
motherboard. This allows the computer to run the
software faster.
6. RAM is further classified into two parts
SRAM
DRAM
SRAM :-
Known as Static RAM. The word “static” refers that the
memory retains its contents as long as the power is
supplied so that’s why we can say this is volatile in
nature. SRAM does not need to be refreshed
periodically . SRAM is faster but more expensive than
DRAM.
7. DRAM :-
Known as Dynamic RAM. It also contains data only
when electricity is available. DRAM needs to refreshed
periodically due to this, this RAM works slower than
SRAM. Mainly general PC uses this RAM because it is
much cheaper than SRAM and requires less space.
8. Known as “Read Only Memory” as the word refers
mainly it can only read the data which in stored in it.
This memory is mainly used by our computer when we
just turn on our computer. It contains BIOS of system.
This is non-volatile in nature.
Mainly there are three types of ROM :-
PROM
EPROM
EEPROM
9. Known as “programmable Read Only memory”. In this
when the data is stored then we have no right to
change or alter any data to it. In this the data is written
by Manufacturer company, even you can also purchase
blank PROM chip but it can be programmed by special
tool such as PROM programmers. In general PC’s
mainly PROM is used because we don’t have to alter
any data to it
10. Known as “Erasable PROM” as the word refers “erasable”
means we can change or erase the data. So in EPROM
we have right to change the data. In this we can change
the data with the help of ultra violet rays. EPROM is
much expensive than PROM.
11. Known as “Electrically Erasable PROM” the type of ROM
which can be erased by electrical charges. EEPROM
can be erased one byte at anytime rather than erasing
the entire chip by ultra violet rays.
12. The place where we store our personal data in computer
system is known as SM. In this we store data so that
when the data is needed we can easily retrieve it.
This is the fundamental component of comp. system.
It is non volatile in nature so that we can not loose
the data when power supply is off.
There are two methods for accessing the data from it :-
1. Sequential – This is the method in which we search
the data sequentially or line by line until you find the
desired data. E.g.. Magnetic tape, etc.
2. Direct – This is the method in which computer can
go directly to the information that the user wants.
e.g. magnetic disk, optical disk, etc.
13. Now I am going to discuss some of the secondary storage
devices :-
1. Magnetic Tape :- Magnetic tape appears similar to
the tape used in music cassettes. It is a plastic tape
with magnetic coating. Mainly it is used to store
music, movie, etc. it is not used to store data in it
because as we know it comes under sequential access
and it reads data line by line so that we can’t find the
exact location of data.
14. 2. Magnetic Disk :- This is widely used popular storage
medium for direct access secondary storage. This is
the place where data are automatically save when we
click on save button. It is non- volatile so that once
data is stored in it will not lost when power goes off.
This is the storage device where we mainly store or
install OS for system.
Some of the magnetic disk are as follows :-
Hard Disk
Floppy Disk, etc.
15. Hard Disk
Hard Disk also known as “Hard Drive” or “Fixed Drive”.
This is the place where we store our data or
information so that we can retrieve for further use.
This is the place where we install our OS so that we can
run our computer. Hard disk comes fix in our system
and if you require more hard disk then it comes in
removable also. The average computer today comes
with a 250 to 500 gb hard drive.
16. Floppy Disk
This is removable, round, flat piece of Mylar plastic,
coated with a ferric oxide. this kind of disk is read and
written by Floppy Disk Drive (FDD), which is a device
which performs basic operations on disk including
reading and writing of data to it. This was used to
transfer data from one computer to another. Earlier 5
¼” floppy disks were used but these disks have less
storage capacity so new format of 3 1/2” floppy disk
came in market. Now a days floppy disk are not used
because off less storage and high rate.
17. Optical Disk
This is the secondary storage medium in which you can
store much more data in it. This is flat, circular, plastic
disk coated with material. Optical disk is very popular
because of its small size and huge storage capacity. You
must have optical disk reader in your computer so that
you can read or write data on it.
There are two types of optical disk :-
1. CD
2. DVD
18. CD.
Known as “Compact Disk”, mainly used to store data, music,
movie, software, etc. it can store 80 minutes of continues
video recording. The space of CD is up to 700 mb. Due to
its high storage capacity it is widely used. The data are store
in it is in the form of “Pitts”. To avail the services of CD your
computer should have CD drive.
There are two types of CD :-
1. CD ROM.
2. CD R/W.
19. DVD
Known as “Digital Versatile Disk”. It is high capacity
storage medium. Mainly used to store movie, music,
software, etc. the storage capacity of DVD is up to 4.7
gb. It looks similar to CD but due to its high storage
capacity it is not cheaper as CD. To avail the facility of
DVD you must have DVD drive in your computer. DVD
drive also gives you facility to run CD disks too.
Types of DVD :-
1. DVD ROM.
2. DVD R/W.
