What is a computer?

A computer is an electronic device,
operating under the control of instructions
stored in its own memory, that can accept
data, process the data according to
speciﬁed rules, produce results and store
the results for future use.

What is a Computer?
A computer is a device that takes
Numbers,Texts,Sounds,Images,Animations,Videos
,... then converts them, and gives back a result
that is Number, Text, Sound, Image, animation or
video.

All Number,Text,Sound,Image,Animation,Video
in input are data and all
Number,Text,Sound,Image,Animation,Video,... in
output are information.

I
A component or peripheral device (such as a barcode reader, graphic tablet, keyboard,
magnetic-stripe reader, modem, mouse, scanner,....) that feeds data or instruction into a
computer for display, processing, storage, outputting or transmission.

Input devices convert the user's actions and analog data (sound, graphics, pictures) into
digital electronic signals that can be processed by a computer. Digital data (such as from
barcode readers, modems, scanners, etc.) does not require any conversion and is input
directly into a computer. It is through input devices that a user exercises control over a
computer, its operations, and outputs.

device (modem, monitor, printer, etc.).

• What is the Data & Information
pyramid? -> present next week.


Storage


Storage
Storage is the place where data is held in an electromagnetic
or optical form for access by a computer processor.


Storage

Storage is frequently used to mean the devices and data
connected to the computer through input/output operations -
that is, hard disk and tape systems and other forms of storage
that don't include computer memory and other in-computer
storage. For the enterprise, the options for this kind of storage
are of much greater variety and expense than that related to
memory.


Storage

memory.

Furthermore storage has been divided into:


Storage

memory.


1. primary storage, which holds data in memory
(sometimes called random access memory or RAM) and
other "built-in" devices such as the processor's L1 cache,
and
