DEFINITION, FUNCTIONS AND COMPUTER COMPONENTS
Welcome to the
Science Lovers, a simple blog to share knowledge with full sincerity. This time
we will share knowledge about the computer, some of the main topics of
discussion was the definition of Computers, Computer Functions, Computer
Components, How It Works and Implementation of Computer Applications.
Today's modern era,
humans are very dependent on life-support equipment. Electronic device is a
type that we unknowingly become a basic requirement that must be met. One type
of electronic items that become a necessity even as money-producing machine is
a computer. Then, what kind of computer should explanation we know? Do not miss
reading the following!
A. DEFINITION
COMPUTER
The word computer
comes from the Latin meaning computare count. In English called compute.
Because the origin of information processing with computers almost exclusively
related to arithmetical problems, but modern computers are used for many tasks
unrelated to mathematics. By definition computer interpreted "A set of
electronic tools that work together, can receive data (input), process data
(process) and providing information (output) as well as coordinated under the
control of programs stored in its memory.
Due to their field
of computer science is too broad, experts and researchers define terminilogi
slightly different computers.
According to
Hamacher et al, in the book Computer Organization, the computer is an
electronic calculating machine which quickly and can receive digital input
information, then process them in accordance with programs stored in memory and
produces an output in the form of information.
According to Robert
H Blissmer, the computer is an electronic device that is able to perform the
following tasks:
- Receive input
- Processes the input corresponding program
- Save the commands and results of processing
- Provides output in the form of information
According Fouri, a computer is a data
processor that can perform large calculations quickly, including arithmetic and
logic operations without human intervention.
According to Donald
H Sanders in the book Computer Today, computer is an electronic system to
manipulate data that is fast, precise and designed and organized in order to
automatically receive and store input data, process it and produce the output
under the control of a step-by-step, the instruction program stored in the
memory (stored program).
From the definitions
above, it can be concluded that the computer is a collection of machine
counters which have a storage area or storage, can receive input data quickly,
to process data quickly, and produce data information quickly that is useful
and in accordance with the wishes of the user (user ). Where the 'Information'
generated by the computer is the application of computers, and the input of the
computer data, so that the computer itself can be said to be 'Process
Transformation' of data into information.
To be more easily
understood, analogy in mind that computer as a human being who has a physical
form and non-physical. The physical form of a human form of the hands, feet,
head, ears and so forth. The composition and the location of each body shape.
As with computers that have a physical form such as a monitor, keyboard, CPU,
and so forth. Physical formed is useless if it does not include non-physical.
Like a human has a soul, a computer has the software to run the system.
B. FUNCTIONS OF
COMPUTER
After reviewing and
understanding the history of computers, all my friend would have been able to
deduce some of the functions of the computer. The following will be clarified
computer functions:
- Computers can perform long distance
communication and distributed quite a lot of information to the Internet
network. This function even enjoyed by children not just adults.
- Computers can control the means of
monitoring such as CCTV (camera remote control), can also control various
automatic machines that we use today.
- Computers can be used also as a means of business in many ways, the
value of the computer is very promising trade and other businesses that use
computers as a tool such as architectural design, programming, companies that
process data up and down the rate of profit, even internet cafes.- The health sector include the functioning of the computer to increase effectiveness and efficiency in the examination of the disease or pregnancy (USG).
- Computers can strengthen national defense
and certain buildings that are automatically controlled by a computer. Such as
CCTV, fire alarms and storing important files state.
- In the field of computer education can
facilitate the learning process we are in preparing materials with a computer
presentation.
- The day-to-day computer and even serves as
a means of entertainment by providing fun games to play.
C. COMPONENTS OF
COMPUTER
In a computer
system, there are three components that can never be separated. If these
components separately, the computer is not going to work. Then, what are its
components?
1. Hardware
(Hardware)
Hardware is a device
that we can touch such a device entry, processing devices, output devices and
storage devices. Tools hardware compilers usually advanced so as to form a
working computer based commands. With the command understood by the computer,
then the command to perform various activities on the machine and run the
appropriate command arrangement. On the hardware are processing device (CPU),
input devices, output devices, and storage devices.
2. Software
(Software)
The software is the
documentation of procedures and programs that serve to solve the problem
desired. Electronic data is a form of software programs or instructions to be
executed by the command. In the software are operating system (OS), application
programs and language programs.
3. Brainware
(Operator)
Brainware is a
person who operates a computer. Orders received computers, all from brain ware.
D. HOW TO COMPUTER
WORK
If a computer is
only made up of hardware only such as a monitor, CPU, keyboard, can not be said
as a computer. Because the computer can work if there are three elements that
qualify namely, hardware (hardware), software (software), operator (brain
ware). Hardware used for command input output media, media processing software
is used as a command and brain-ware is computer users (operators) are useful as
giving a command and users of data processed by computer.
The workings of
computers generally use three main elements of this. Thus, brain ware entering
commands or input into the computer via hardware such as keyboards, rescan,
microphone etc. Command input is entered earlier in the process in a computer
with a processor that functions as the brain of the computer. This processor
which processes all the commands into machine language that is easy on your
thigh by means of an electronic computer. Orders that are processed earlier
displayed in the form of the output (output) in the form of data via hardware.
Sample results for example printed output paper through the printer, the sound
through the speakers via the video monitor. All output is displayed
computer-supported audio software eg software should be supported winamp, vlc,
kmpplayer etc. Had the data to be processed is the number to be supported by
the software microsoft word, excel, power point etc.
Application of
Computer Applications
The world is
undergoing a process of revolution the application of computer technology
called "Computerization".
1. Engineering and
knowledge
Computer Aided
Design / Computer Aiden Manufacturing (CAD / CAM), the design using computer
assistance. Three Dimension Interactive Computer Aided Automation)
2. Business Sector
Management
Information System (MIS), An information system that can provide any
information to management for
making a decision. Decession Support System (DSC), a system of decision-making
3. Industrial Sector

- APT (Automatically Programmed Tolls)
- A computer to regulate the supervision of
the production process automation industry.

computer to take pictures of the whole organ.
- DSR (Dynamic Spatial Reconstructor), to
take the organs that move
- SPECT (Single Photon Emission Computer
Tomography), detecting particles of the body

scheduling system and ticket booking system.
7. Field of Crime
- CASP (Crime Analysis Support System),
identify a region the possibility of criminality.
- PROMIS (Prosecutor Offender Management
Information System), a system of information on the evidence of the accused to
court.
- Cath (Computer assited Terminal Criminal
Hunt), a system that can menampilakan description of the suspect.

criminal background, complete with details.
- ARJIS (Automated Regional Justice
Information System)
