How are your efforts in training the computer operating
Preamble:
Creative is an
institute for basic computer training and education. So I will post of
the articles in a tutorial of basic computer operating. The
operating system's of computer own efforts on this blog have tried to describe
the art techniques. I believe this text will benefit to beginner
and new users . If someone
were to benefit from
my writings, then I would be blessed
and be successful
in my attempt. So not to say other than that, I'm going back to the original post.

Computer operating system (Basic Course)
Introduction :
It is undeniable that the modern era of
twenty-first century science, science is one of the
most phenomenal discovery
of the device in the computer. It's a plain calculator
for ordinary human, which can be done automatically. But he is a skilled
computer technicians with a sophisticated electronics device which receives
data via the data processing instructions that it should be preserved, and that
the solution to the problem.
What is Computer?
A varied job performance computer
electronics device which receives data, through the data format and analyze the
information that should be preserved on disk or in memory. And all necessary information
can be found by using the desired results. Simple words, the computer is an
electronics device. Computers (Compute) of the count. Therefore its considering
that the calculations done by machines or computers in the device. Computer is
automatic problem solving machine whose main purpose is data processing or
processing information and which is represented electrically.
The origin of the word computer from the Latin
word 'compute. Computer-ending sense of the
counting machine. Although computers have been invented as a counting machine,
but the machine is not just limited to the work. Computers
to do research,
as well as being used in the house.
Computer data in order or Computer information given command :
From the computer can not do anything. But if this is the correct command
to the computer, its do this work. The command for this,
we have to use the
keyboard and mouse.
There
are four things we see outside of a computer : For example, the
(1) Keyboard : The type of information we provide to the command of the keyboard.
(Ii) Mouse: We can provide the computer with the mouse.
(1) Keyboard : The type of information we provide to the command of the keyboard.
(Ii) Mouse: We can provide the computer with the mouse.
(3)
CPU : The information
provided in this part
of the computer in
the here এন্ড after
is processed. English meaning of
the - C = Central, P = Processing, U = Unit , processed at the same time in the
office area of the Central Processing Unit.
(4) monitor: output is sent to the CPU, this part is just like a Television.
(4) monitor: output is sent to the CPU, this part is just like a Television.
Computer work processes can
be divided into
roughly two.
(1) Input Unit: Accept the area. This area is keyboard and mouse.
(Ii) Output Unit: This is shown in the results, This area is CPU and monitor.
(1) Input Unit: Accept the area. This area is keyboard and mouse.
(Ii) Output Unit: This is shown in the results, This area is CPU and monitor.
Input devices are- The purpose of the
communication is done with computer input devices. Conversion
of any data or information
in binary electronics signal (zero and one) are sent
to the CPU. This is because the CPU
(0, 1), except that it does not do anything.
Output devices are- Electronics signal input from existing
human understandable image, alphabet, numbers,
words and pictures
Etc. into shape.
The importance of
computer instructions;
Computer instruction
is important. The Right to
Information can only display the Right results. The results will be displayed in
the wrong direction if it is wrong. The wrong direction can cause serious
inconvenience.
What
are the
computer works
?
The four most important works in the computer. For example,
(1) It receives the input device and the number of words.
(Ii) the data or information databases through the process of instruction.
(3) The results are sent to the output device.
(4) According to the requirements of data stored in databases, data from the memory or memory resources are withdrawn.

Types of computers;
There are three types of computers in the world; For example:
(1) Digital Computer, (ii) analog computers, (3) hybrid computer.
Digital computers have been divided into 4 . For example:
(1) Super Computer, (ii) The main frame computer, (3) Mini-computer, (4) Micro computer.

Computers in different
parts of the-
(1) CPU (b) Monitor (3) Keyboard (4) Mouse (5) Mouse pad (6) Printer (7) disk (8) Speaker (9) Modems (10) Scanner, etc..

to type or use the keys. For example: if you write to any noun by first notify
you hold down the Shift key and write first alphabet. And then others alphabet
write to hold up the Shift key will be required. The Bengali alphabet
writing above and below this key is used to type text. Not only
that, the Shift key and the function key press the different commands use
to the computer.

Alt key: This is different for different programs in different directions and different commands can be used.
Enter key: The key to effective use of the computer to which it is directed. To create a new paragraph for writing a paper on this key is used. Its a command key.
Pause Break key: If you have any difficulty in reading speed is the key for you to read it.
