Understanding the size-speed Internet access

1. Channel used

• Dial Up
• Dial-up is an easy way to connect our computer to the internet using the phone lines. This has advantages because it has a wide network. Provided that we have a phone connection, so we can access the internet. speed access using a dial-up can reach up to 56 kbps. Meanwhile, if the dial-up supported with data compression technology Power Surf Dial Up, speed can reach speeds of 5 times usually.
• GPRS Network
• GPRS (General Packet Radio Service) is used in mobile phone so that it can communicate data and voice. Dansuara data communication is used dngan media using radio waves. Have GPRS data transfer speeds up to 115 kbps. Because of this speed, it became one of the GPRS technology for data communications is a lot at this time. Terms for access to GPRS, the computer, mobile phone (mobile phone) with GPRS, the SIM card (have facilities GPRS)
• Wifi
• Wifi (wireless fidelity) is a network with wireless technology that uses a certain frequency waves, high level, reaching the 2.4 GHz spectrum. This tool can be used origin we are still in the area that has Wifi signal, namely the radius of 100 meters from the access point.
• Cable TV channel
• cable TV network has a data communication path and the width can be used to send voice and movement. When we use this channel to the internet, we get a fast internet access

2. Provider that is used
Speed transfer of data from a server computer to computer on the internet we highly depends on the speed transfer of data from providers that we use. Speed range 28.8 kbps modem, 33.6 kbps or 56 kbps, while decepatan telephone network in Indonesia, ranging up to 9.6 kbps 28.8 kbps.
Bandwidth (width of the channel data) is the width of the channel data passed simultaneously by the data transferred. Bandwidth can diibaratkan nets as a highway that passed many vehicles (data) at the same time. The more vehicles on the slow pace vehicle. The wide bandwidth is used the more data that can be transferred. We need to know this to be able to consider or compare with other ISPs.

3. computer on the number of local networks that are connected to the internet
local network dihibungkan de Internet through the relevant channels of communication in the computer server. Access to the Internet is divided enjadi some path through the hub to some of the client computer. Throughput on the client computer can be calculated with a simple formula as follows.
Client Throughput (t): 500 bytes / second (per client)
Bandwidth to the Internet: n * t * 8
Thus, the channel data throughput are expected to have 500 bytes / second and tedapat client 20, the channel is required on the client at least 20 * 500 * 8 = 80 kbps. 64 kbps is considered a channel on each client to achieve sufficient throughput 500 bytes / second per client because the calculation is valid if the client simultaneously transfer data.

4. Equipment used
Hardware to build internet connection using dial-up connection the computer, modem, and phone lines. In addition, the required account from the ISP (Internet Service Provider).
Data should be from the ISP is
Username: @ telkomnet such as IM,
Password: telkom for example,
Primary DNS: 202.134.0.155 for example,
Secondary DNS: 202.134.2.5, for example, and
Dial up phone numbers: for example 080989999
