INTRODUCTION
Background
The rise of internet user already become part of our daily life. This is because the
use of information in cyberspace will be important in everyday life. These
characteristics are one of the effects of globalization in Indonesia.
We often do a good interaction with other people in the exchange of information
text, images and sound through the tools or devices that we use (electronic media
or other media).
Communication is what we use are almost always present in everyday life. The use
of the Internet as one of the networks that we use in communicating data to the
public free of charge makes it easy to communicate. To be sure, the Internet is one
of the communication data very widespread among the general public. So what is a
data communication? For more details about the data communication network
based in the paper are We learn this.
Basis Theory
Computer Network
Computer network (the network) is a system that consists of computers that are
designed to be able to share resources (printer, CPU), communication (e-mail,
instant messaging), and can access the information (web browser). [1] The purpose
of the network computer is [1] In order to achieve its objectives, each part of the
computer network may request and provide the service (service). [1] The party
requesting / receiving services called client (client) and that provide / send service
called the waiter (server). [1] This design is called a client-server system, and is
used in almost all computer network applications. [1] Two computers, each of
which has a network card, and then connected via a wired or wireless as a data
transmission medium, and there are devices Network operating system software
will form a simple computer network. [2]: If you want to create a computer
network that is wider-reaching, it would require additional equipment such as
Hubs, Bridges, Switches, Routers, Gateways as interconnection equipment.
Data Communications
Data communication is the process of sending and receiving data / information
from two or more devices (tools, such as a computer / laptop / printer / and other
communication devices) are connected in a network. Both local and wide, like the
Internet.
CHAPTER II
DISCUSSION
1. UNDERSTANDING COMMUNICATION DATA
Data communication is the transmission or the process of sending and receiving
data from two or more devices (source), through multiple media. The media can be
a coaxial cable, fiber optic (fiber optic), microware and sebagainya.Komunikasi
data is a combination of several data processing techniques. Where
telecommunication means all activities relating to the transfer of information from
point to another. While the data processing are all activities related to the
processing yag.
1. TYPES OF DATA COMMUNICATIONS
In general, the types of data communication are divided or classified into two
kinds:
1. terrestrialAksesnya infrastructures using wired and wireless media. To build
this terrestrial infrakstuktur high costs, limited bandwitch capacity, high
costs due to the use of cables is not diprngaruhi by weather factors so that
the signal is strong enough used.
2. Through the use of satellite satelit Aksesnya. Areas covered satelit wider
access so as to reach a location that can not be reached. By terrestrial
infrastructure but for a long time need for ongoing communication process.
Because of the interference due to solar radiation (sun outage) the most
severe occur once every 11 years
Of both types can be divided into two forms of data communication. System
communicates the data can also be formed offline communication system
(communication system offline) and on line communication system (on-line
communication system)
1. 1. System communication offline
Offline communication system is the process of sending data by using
telecommunications to data processing center but will be processed first by using a
modem terminal then sent via telecommunications and proceed directly by the
CPU data is stored on a floppy disk, magnetic tape and other equipment necessary
1. Terminal, 1/0 It is a device to send data and receive data remotely with
telecommunication facilities. Terminal equipment is a magnetic tape unit,
disk dirivepaper tape.
2. Lines of communication, Track a communication facilities such as
telephone, telegraph, telex etc.
3. Modem, A device that transfers data from a digital code system analogous to
the system code.
CHAPTER III
CLOSING
CONCLUSION
Thus, based on the data communications network that is sending data that can not
be separated from the performance of the device – an electronic device as a
medium to transmit data from one terminal to another terminal or from one
computer to another computer, one of which uses the internet.
Interaction or relationship is in purpose to transmit or receive data between devices
both within a narrow range or wide reach.
