HOW TO
WORK COMPUTER
Memory
In this system, memory is a numbered
sequence of bytes (such as "cell" or "pigeon holes"), each
containing a small piece of information. This information may be a command to
tell the computer what to do. Cell may contain data which is necessary for the
computer to perform a command. Each slot may contain one, and what is now the
data might then be perintah.Memori storing various forms of information as
binary numbers. The information will not be solved in the form of binary
(encoded) with a number of instructions that turn it into a number or sequence
of numbers. For example: The letter F is stored as a decimal number 70 (or binary
digits) using one of the methods of solving. More complex instructions could be
used to store images, sound, video, and various kinds of information. The
information can be stored in a single sell is called a byte.
Processing
Central Processing Unit or CPU (Central Processing Unit) role is to process the orders given by computer users, manage it with the data on the computer. Processing units or devices will also communicate with the input devices, output and storage to carry out instructions that are interrelated.
In the original von Neumann architecture, he describes an Arithmetic and Logic Unit, and a Control Unit. In modern computers, the second unit is located in a single integrated circuit (IC - Integrated Circuit), which is usually called a CPU (Central Processing Unit).
Arithmetic and Logic Unit, or Arithmetic Logic Unit (ALU), is a tool that performs basic implementation such as the implementation of arithmetic (addition, subtraction, and the like), the implementation of the logical (AND, OR, NOT), and the implementation of comparison (eg, compare the content as much as two slots for equality). At this unit done "working" real.
The control unit stores the current command is performed by a computer, instruct the ALU to carrying out and get back information (from memory) required to carry out the order, and move back the results to the appropriate memory location. This unit serves to control the reading of instructions a computer program.

Input and
results
I / O allows
a computer to get information from the outside world, and put his work there,
it can be physical (hardcopy) or non-physical (softcopy). There are all sorts
of tools I / O, from the familiar keyboard, monitor and disk drive, to the more
unusual such as a webcam (web camera, printer, scanner, and so on.
Owned by all
the usual input devices is that they encode (convert) information of a kind to
the data that can be further processed by a digital computer system. Tool
output, decode the data into information that can be understood by the computer
user. In this sense, a digital computer system is an example of a data
processing system.
Directive
Commands discussed above are not commands like human language. Computer only has a limited number of simple commands in well-defined. Common commands that are understood most computers are "copy the contents of cell 123, and a place in the cell clone 456", "add the contents of cell 666 to cell 042, and place result in cell 013", and "if the contents of cell 999 are 0, the next command you in cell 345 ".

Instructions
are represented as numbers in a computer - code for "copying" may be
001, for example. A set of specific commands are supported by a particular
computer is known as machine language. In practice, people usually do not write
orders for computers directly in machine language but use programming language
"high level" which was later translated into machine language
automatically by special computer programs (interpreters and compilers). Some
programming languages closely related to machine language, such as assembler
(low level language), on the other hand, languages like Prolog are based on
abstract principles far removed from the actual implementation details by
machine (high level language).
3. Computer parts
Computer consists of 2 major parts of
the software (software) and hardware (hardware).
Hardware
Processor or CPU as the data processing unit
RAM memory, which store data temporarily
Hard drive, semi-permanent storage media

RAM memory, which store data temporarily
Hard drive, semi-permanent storage media
Input devices, media used to
enter data to be processed by the UPS, such as mouse, keyboard, and tablet
Output devices, the media used to
display the output of CPU processing, such as monitors, speakers, plotters,
projectors and printer
Software
Operating system
Basic program on the computer that connects users with computer hardware. The operating system used is Linux, Windows, and Mac OS. Operating system tasks including (but not only) set the program execution on it, coordination of input, output, processing, memory, and software installation.
