BASIC COMPUTER ENGINEERING

INTRODUCTION TO COMPUTER BASICS
The computer comes from the word to compute the mean count. According V.C. Hamacher, Z.G. Vranesic and S.G. Zaky Computer Organization incorporated in, the computer meets the definition of a fast electronic calculating machine that can receive digital input information, process it in accordance with a program stored in memory (stored program) and generate output information. Another opinion about the computer according to the American Standards Institute and has been discussed and approved at a meeting of the International Organization For Standardization Technical Committee, the computer is a
data processing (data processor) that can perform calculations yag big and fast, including large arithmetic or logic operations, without intervention from humans to operate them during processing. Computer is formed from standardized parts, including additional components and expansion cards to perform a specific function on a computer.
The ultimate goal of a computer system is to process data to produce information. In order for the principal purpose is done, then there must be elements that support it. These elements brain ware (human), hardware (hardware) and software (the software). The three elements of the computer system must be interconnected and form a unity. Hardware without software, it will not function as expected, only in the form of inanimate objects only. The software will operate its hardware. Hardware that is supported by the software also will not work if there are no humans that operate them.

A. brainware
An operator or person involved in the operate and regulate the computer system which can also be referred to as a user. Brainware can be categorized into two (2), namely:

1. Laterat computer
Category Laterat computer is a user / users who have knowledge and understanding of the computer and how the tool is used. A computer does not have laterat
the ability and skills to analyze damage, utilizing computer-based applications for interfacing, identifying and selecting components that transform both the best performance as well assemble them into a complete computer and can operate.


2. Competent computer:
A competent master computer used computer terminology, master parts function computer system, and have the skills to use computers to produce information or perform the desired tasks. This category also has the ability to identify and select the components of a good computer for the best performance. A Diploma in Telecommunication Engineering and Air Navigation is expected to have a competent computer category for Telecommunications and Air Navigation equipment currently operated using a computer system so that a technician is required to always be ready for the arrival of the latest computer technology.

B. HARDWARE

1. Basic Components of Computer Hardware
Also called hardware or hardware is the equipment in a computer system that can be physically seen and touched. The components of computer hardware includes: Motherboard (mother board / main board), microprocessor (called processors only), RAM, Cassing, VGA Card, Disk
Drives, hard disks, CD ROMs, monitors and others. Computer system hardware can be classified into five (5) groups; Input Devices, Output Devices, Processing Device, Storage Device
and Communication or I / O Device. These units are connected to one another. The units of I / O is used for communication between the representation of internal information of the electrical signals in a computer with an external representation such as terminals, printers, and devices or control sensor. Programs
stored in memory and is done by the CPU. CPU reads the description, or representation of each program from memory, read data necessary to execute each step or process each step of the program, and then returns the results to the appropriate memory.
