Hardware For Internet Access
To be able to access the Internet, there are several hardware devices (hardware) that are required are:
1. Computer
2. Modem
3. Telephone channel
1. Computer
Computers are a major component to be mengkases Internet. Specifications used in the computer internet connection is fast or slow performance determines internet access. the higher the specification of a computer, the faster the performance of Internet access, and vice versa.
Minimum specifications of a computer in internet access among others as follows:
o Processor
is the brain of the computer to run applications in a computer. Minimum Pentium III 500MHz processor.
o RAM (Random Access Memory)
serves as a temporary storage media. Minimum 64MB RAM
o Hard Drive
used for magnetic data storage media. At least 10GB hard drive

is the hardware for menampilakan image on the monitor screen. At least 4MB of VGA cards
o Monitor
an output device to display the work process of the computer.
2. Modem
Modem acronym derived from modulator demodulator. Modulator is a part that converts the signal into the information carrier signal (carrier) and ready for delivery, while the Demodulator is the part that separates the information signal (which contains data or messages) of a signal (carrier) that accepted so that the information can be well received. Modem is the combination of both, it means the modem is a two-way communication tool.
In short, the modem is a tool to convert digital signals into analog signals your computer and vice versa. Computers that connect to the internet connected to telephone lines via modem. Based on its function divided menjai three types of modems. Among others:
Modem Dial Up
Dial Up Modem commonly used by the Personal Computer (PC) is directly connected via phone lines. Type of dial up modems have two types, namely:
1) Internet Modem
Modem is installed in the computer, especially on the available expansion slot in your computer mainboard. Average speed of the internal modem to download is 56 Kbps. The advantages of using an internal modem bellow.
a) More efficient places and more economical price
b) Does not require an adapter so impressed a lot more concise without cables.
While the weakness of the internal modem as follows:
a. This modem does not require the indicator light so it is difficult to monitor modem status
b. This modem does not use the voltage source itself and thus require power from the power supply. This causes the temperature within the CPU box to get hot.
2) External Modem
External modem is a modem that is located beyond the computer CPU. External modem connected to a computer via USB Ort com or. Installation of this modem by connecting the modem to the power adapter and connect it again then reconnected to the mains. Gain an external modem:
a) Portability is good enough so that it can move around to use on another computer
b) Equipped with indicator lights making it easy to monitor the status of the modem.
The weakness of the external modem.
a) the price is more expensive than internal modems
b) takes place or a separate location to put the modem.
• Cable Modem
Cable Modem (Cable Modems), is hardware that connect a PC with a TV connection cable. This cable TV network can be used to connect to the Internet at speeds higher than dialup modem or ADSL modem, cable modem speed of maximum 27Mbps downstream (to the user's download speed) and 2.5 Mbps upstream (upload speed of the user). Before you can connect to the internet, then the user is required to perform registration service provider for cable TV and ISP (Internet Service Provider).
• Modem ADSL (Asymmetric Digital Subscriber Line)
ADSL or Asymmetric Digital Subscriber Line is a form of DSL technology. Characteristic of ADSL is its asymmetric, ie that the data are transferred in a different speed from one side to another. Main idea of ADSL technology to break adalh telephone line signal into two parts for voice and data. This allows users to has to or meneima calls and connect to the Internet simultaneously without interrupting each other.
3. Phone Line
Phone lines is also an important and hardware required to connect a computer with internet. The use of telephone sauran was also followed by the use of modemdial ups. In addition to phone lines, to make Internet access can also be done by using cable TV. To be able to access the internet using a modem, the cable TV network used is a cable modem.
SOFTWARE (Software)
SOFTWARE (Software) That is a collection of data as well as instructions that can be executed by the computer. Generally, software is divided into five types:
1.Operating System
Is a program created to control and coordinate the activities of a computer system. Operating System generally made for a particular type of computer.
Example:
Microsoft Windows 1995
Microsoft Windows 1998
Microsoft Windows 2000
Microsoft Windows ME
Microsoft Windows XP
Of Microsoft Windows Vista
Linux Mandrake
MacOS for Apple Macintos
SunOS for Sun Computers
OS / 2
AIX
OS/390
Windows CE for Palmtop
2. Programming Language
Is the program used to translate instructions written in a programming language into machine language that is understandable by computers.
Programming Language consisting of:
a) Low Level Language Program (Program of low-level languages) example:
COBOL (Command Business Oriented Language)
FORTRAN (Formula Translator)
b) High Level Language Program (high level language program) Example:
BASIC (Beginners All-Purpose Symbolic Instruction Code)
Fox Pro
Visual Basic
Visual FoxPro
3. Application Program
Program is the result of the Programming Language and is used for the purposes of special perluan
Example: Program on Taxation, accounting, hospitality and others.
4.Package Program
Is a program created by the software manufacturer for the purposes of a general nature.
The program package consists of:
a. Word Processor (word processor), for example: WAS, WP, Lotus Amipro, ChiWriter, Microsoft Word, Symphony Document.
b. Spread Sheet (processor number), for example: Lotus123, Microsoft Excel, Quatro Pro, Symphony Spread Sheet.
c. Data Base (Data Processing), for example: dBASE IV, Microsoft Access
d. Desktop Publishing (combine text, graphics and tables in one document), for example: Ventura, Page maker.
