The development of information

The development of information and communication technologies in line with the progress of time requires increased knowledge and skills in using the technology tools. For that, we need to study and understand the technology well in order to provide more knowledge and information up to date. In the face of the development of information and communication technology, we are required to learn at an early age so that we can contribute optimally. This material is intended can provide most of the material for you to have enough stock to understand the use of information and communication technology equipment, and understand the future prospects. With this material also expected you have a horizon of thought and knowledge in general and in particular that today many are needed in everyday life. Until the current information technology is growing very rapidly along with the discovery and development of science in the field of information and communication. It is able to create tools that support the development of information technology, ranging from communication systems through a direct communication tool as well as a two-way (interactive). Basically, information technology equipment includes three main tools: A. Computer systems; B. Network Communication Systems; C. Net Tools. A. Computer Systems Computer is an electronic device that is capable of receiving, processing, and storing the data, and generates output in the form of text, images, symbols, numbers and sounds. In operation, the form, the system and its function, the computer consists of two (2) parts: hardware and software. 1. Hardware To meet the demand for the kinds of information, people always to develop the hardware to support it. To accommodate this interest, he creates a variety of tools that support these desires. Computer hardware devices can be grouped into an input device (Keyboard, Scanner), the process (including: CPU), output and storage devices (such as: monitors, and printers), and a data storage device (such as: CD-ROM, Compact Disc, floppy disk, Hard disk). Details on computer you will earn well Keyboard is a tool to enter data or commands to the CPU (Central Processing Unit). The keyboard usually consists of a series of letters and numbers. Scanner is a tool to enter data such as image / graphics and turn it into a digital form that can be processed and combined with the form data in the form of text. Central Processing Units (CPU) is tool that serves as a processor (processor) data. CPU is a series circuit that stores instruction-processing instructions, and temporary data storage. Monitor is a tool that can display text or image of the data processed in the CPU. The printer is a tool to produce a data output (output) print the form, either in the form of text and pictures / graphics. CD Rom is an additional tool (instrument peripherals) that is capable of storing and write data and programs through media Compact Disk (CD). This tool is designed to be able to write and read data or program through Optical system. Compact Disk (CD) is a storage medium made of plastic material. The process of storing and reading data using an optical system. Software is a computer program that contains a set of instructions that is made using a special language. This Program, gave orders to the computer to perform various operations / processing of the data contained in the program or the data entered by the user computer. In short the software is a 'soul' while the hardware to function as a 'body' in a computer. In general, the software can be classified into two (2) classes of system software and application software. Discussion specifically about the software you will get on another occasion. B. Network Communication Systems Communication network is a system that is able to connect and combine multiple points of communication into a single entity that is capable of interacting with one another. Telephone is a two-way communication tool that allows two or more people to talk without being limited distance. Integrated Services Digital Network (ISDN) is a specialized communication network that uses the telephone network meproses not only sound, but also able to handle data storage in the form of text, images, video, fax, and others. Facsimile is a tool that is able to send documents in exactly the same over the telephone network. Fiber optic is a communication network that is capable of transmitting data in high frequency. In this network communication paths do not use copper wire but uses light as a conductor of the data. Leased lines are fixed telephone network (permanent) that connects two or more sites. This network does not have the tools switcher (switching) or the like, this network working between places that are specifically linked or predetermined. This network is also known as private line. Wirekess is Wireless communication network. Communications network that uses radio waves / specific frequency that serves as a conductor of information. This communication network using a transmitter, amplifier, and the wave receiver that contains the data. Wireless communication network that uses satellite that serves as a transmitter, receiver and amplifier. The communication system using wave as a conductor of data The antenna is a device used to transmit and receive radio communications. TV and Radio is a means of delivering information (mass media) that uses sound waves as a conductor signals and images. Mobile communication is communication that uses radio transmission to transmit signal information, the tool is better known by the name of mobile phones. C. Net tools Various ways humans use to facilitate and maintain the quality of the connection through the internet. Since then, the tools that support the ability to network (net tools) is growing rapidly. Network system that was only used by a limited circle now very familiar even to the household level. 1) Server A computer that works as a data provider, the provider of software and data storage is server. Even a server capable of regulating the flow of information in a network that regulates. 2) Client Client is a personal computer (PC) in a communication network that has the ability to process the data and is able to ask for information to the server. 3) Router A router is a device used in a network that is able to transmit data to other networks through more quickly, accurately and efficiently. 4) Modem Modulator / Demodullator is a tool that allows PC, Mini Computer, or mainframe to receive and send data in digital form through the channel telephone.
