per canggih. Selengkapnya silakan kunjungi http://www.centrin.net.id e. Provider Seluler lainnya Saat ini hampir semua provider seluler di Indonesia menawarkan jasa layanan internet atau ISP. Layanan ini biasanya berbasis quota yang dapat diaktifkan dengan paketan tertentu, ISP jenis ini sebagai pilihan cocok untuk Anda yang hanya sekedar koneksi internet.

Understanding the Internet Service Provider (ISP)

Internet Service Provider (ISP) is a service provider company on internet connection services with other interconnected services. This ISP has infrastructure as a means of telecommunications connected to the internet. ISP will share the capacity of its Internet connection for its customers who need internet services. Usually subscription system has been established first provisions. This subscription system is paying monthly. There are also other telecommunication providers that implement subscription systems by using quota based systems.

The existence of an internet service provider is currently very much needed, the reliability of this system will affect the speed of the connection. Before choosing a subscription with a particular ISP, some things to note are:

a. Transfer speed

You should ask how much speed for maximum data transfer on the provider's offer. Transfer speed
data
each ISP is different. The faster the data transfer on an ISP, then it can be said the provider is getting better.

b. Type of modem

1. Analog modem (dial-up modem)
This modem is a modem that can receive data in the form of analog signals through the data transmission network and converted into digital data to be sent to the computer or vice versa. This modem is usually used for dial-up connections over the telephone network or in other words the computer network access through telephone lines by using a modem. Dial-up is usually used privately at home. Computers that can use a dial-up modem are generally single computers / PCs. This modem is available in various speed options such as 14.4 kbps, 28.8 kbps, 56 kbps.

2. DSL Modem (Digital Subscriber Line)
This type of modem is used to receive and transmit data with digital technology through a dedicated network. This technology will make the data received or sent DSL modem into digital data so that internet access will be faster when compared with analog modem. There are two types of DSL modem namely ASDL (Asymmetric Digital Subscriber Line) with faster download speeds than upload and SSL (Symmetric Digital Subscriber Line) with download speed equal to upload speed.
3. Cable Modem
A cable modem or cable modem is a hardware device that connects a PC with a cable TV connection. This cable TV network which is then used as internet connection with maximum speed is 27 Mbps downstream and 2.5 Mbps upstream. To be used as a cable modem, your computer must be equipped with an ethernet card (ethernet card)
4. CDMA Modem
This type of modem using internet communication system through CDMA (Code Division Multyple Access). In general CDMA modem is shaped like a USB Flashdisk that you can use anytime. CDMA internet speed can triple the dial-up connection.
5. GSM Modem
This type of modem has similarities with CDMA modem. This modem has internet communication line with GSM (Global System for Mobile Communication). Like a CDMA modem, GSM Modem is also shaped like a USB. This modem you can use on laptop or PC. The advantages of this modem is with features 3G, 4G, and HSPA which can make the data transfer will be faster.

Modems used by ISPs to connect quickly are different. Therefore, choose an ISP that is able to offer digital modems that use cable and modem that has support 3G-based technology for internet connection that uses wireless.

c. Internet connection comparison

the number of connections that are shared for the customer ideally a maximum connection of 10 places to avoid the slow internet connection.

d. Additional features

You must carefully select the features offered. The more menus or features offered indicate the ISP is more reliable.

5.modem
the term modem is better known as Hardware which is often used for communication on computer.Data from computers in the form of digital signals is given to the modem to be converted into analog signals. Such analog signals can be transmitted through several telecommunication media such as telephone and radio.Upon arrival at the destination modem, the analog signal is converted to digital signal back and sent to the computer. There are two types of modems physically, namely external modem and internal modem.Modem is divided into:1. An analog modem is a modem that converts analog signals into digital signals2.Modem ADSL3. Cable modem is a modem that receives data directly from the service provider via Cable TV4. CDMA Modem5. 3GP Modem6. GSM Modem

The routing process occurs in layer 3 (Network layer like Internet Protocol) from the OSI seven-layer protocol stack.The router serves as a link between two or more networks to pass data from one network to another. Different routers with switches. Switches are connecting several tools to form a Local Area Network (LAN).In general, the router is divided into two types, namely:* static router (static router): is a router that has a static routing table that is manually set by network administrators.* dynamic router (dynamic router): is a router that has dab create dynamic routing tables, by listening to network traffic and also by interconnecting with other routers.
7. Network Cardnetwork_card.jpg
(English: network interface card abbreviated as NIC or network card) is a card that serves as a bridge from a computer to a computer network. Type of NIC in circulation, is divided into two types, namely the physical NIC, and a logical NIC. Examples of physical NICs are NIC Ethernet, Token Ring, and others; while a logical NIC is a loopback adapter and a Dial-up Adapter. Also known as Network Adapter. Each type of NIC is given an address number called a MAC address, which can be static or user-modifiable.

8. Bridge Network
https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgjM3wU9ZfVylSv6wiXnPC4BGZTIns9v3LqSKmAMQEnjF8_fUKJUeCfUz4WlKv28kEwhivT5AAVSc_LSVXTBkWO0kw9bd0-I3nSYfVYb52DhMNGumv4w5YLQH9N-hx1aBkirYGt2_D54Rg/s1600/bridge.bmp is a network component used to extend a network or create a network segment. The network bridge operates within the data-link layer on the OSI model. The bridge can also be used to combine two different network media, such as between Unshielded Twisted-Pair (UTP) cable media with fiber optic cable or two different network architectures, such as Token Ring and Ethernet. The bridge creates a signal transmitted by the sender but does not convert to the protocol, so that two network segments connected to the bridge must have the same network protocol (as well as TCP / IP). Network bridges also sometimes support the Simple Network Management Protocol (SNMP) protocol, and some have other diagnostic features. There are three common types of network bridges:Local Bridge: a bridge that can connect local network segments.Bridge Remote: can be used to create a link (link) between the LAN to create a Wide Area Network.Bridge Wireless: a bridge that can combine a wired LAN network and a wireless LAN network.

An important step to make an internet connection is to install hardware in the form of a modem. A modem is an intermediary device between a computer and a telephone line to connect to a telephone line in order to connect with an ISP that provides internet services. In the internet connection through the ISP there are several steps that must be done, namely Installing Dial Up Modem, Installing Dial Up Networking, Internet Connection via ISP.

Kinds of IP Address Type

v Public Address is the IP Address used for communication on the network on the internet, for example when we first access the URL
http://www.google.com, then our computer will automatically connect to address 72.14.203.147. these numbers can be seen in the status line in our browser (Internet Explorer / Mozilla Firefox) located on the bottom left. Number 72.14.203.147 is the IP address that is used in the Internet network and classified as Public Address.

v Private Address is an IP Address used for communication that is not directly connected to the internet or is in a local area. By using this Private Address, the computer can not connect to the internet. Can only exchange information with other computers that are also connected on the same network (intranet). Private IP is usually used in an office. The number used usually starts with 192.168.0.1 onwards as much as the existing computer.

v IP Dynamic is the ip given from the dhcp server (isp) will usually change every time you disconnect, then re-connect (restart the computer, etc.) does not need additional configuration, just set your connection config from ip to dns to auto-mode.

v IP Static ad ip allocated and given directly from the isp. you need to enter the ip you allocated from your isp to your connection config. so that your time is disconnected and re-connect (restart the computer, ip amu will not change) ip dynamic is usually used by most home users and soho (small office, home office) static ip usually used by most professional, server, and enterprise users.
