Modem Functionality
Modem function is to convert voice signals into digital signals and vice versa. Today the modem has been developed with a range of facilities that are useful, for example
Voice Modem
With this facility, voice modem, change the modem function not only as a connector to the internet but more than that, the modem can be a radio channel, audio, streaming video to a phone conversation. In fact it's been a lot of modems that have facilities that can be as answering machines and voice recorder.
Fax Modem
It works like a fax modem facsimile, with a specially designed software, can convert the modem into a facsimile machine, where the modem to change analog signals into digital documents and raised back into the image file if the return is received or a fax modem into a printed document if the receiving is a fax machine.
Types Of Modem Based Installation
Based on computer device mudem installation consists of two types, namely the internal modem and external modem. Internal modem in the pair on the inside of the CPU such as the PCI slots (on certain motherboard is equipped with a modem from the manufacturer), while external modems installed on the outside of the CPU, generally in the pair on the Serial or USB port on the CPU.
Computer Internal Modem
Some computers have an internal modem is a modem built inatau computer modem card. For a computer modem card, a PCI slot or ISA slot sometimes in need, depending on the motherboard interfaces are available to receive the modem.
Voice Modem
With this facility, voice modem, change the modem function not only as a connector to the internet but more than that, the modem can be a radio channel, audio, streaming video to a phone conversation. In fact it's been a lot of modems that have facilities that can be as answering machines and voice recorder.

ROUTER
The router serves as the primary liaison between two or more networks to carry data from one network to another. The difference with the switch is a switch that is connecting several devices to form a Local Area Network (LAN).
Routers use a lot in technology-based network protocol TCP / IP, and the router type is referred to as an IP Router. In addition to IP Router, there is another AppleTalk router, and still there are several other types of routers. Internet is a prime example of a network that has a lot of IP routers. The router can also be used to connect many small networks into a larger network, called the internetwork, or to divide a large network into several subnetworks to improve performance and simplify management. Routers are sometimes also used to connect two networks that use different media (such as wireless routers in general than he can connect a computer with a radio, it also supports connecting a computer with a UTP cable), or different network architectures, as well as from Ethernet to Ring.Router Token can be used also to connect a LAN to a telecommunications service as well as the telecommunications leased line or Digital Subscriber Line (DSL). Routers used to connect a LAN to a leased line connections such as T1, or T3, commonly referred to as an access server. Meanwhile, the routers used to connect the local network to a DSL connection is also called the DSL router. These types of routers generally have a firewall function to perform packet filtering based on source address and destination address of the package, although some routers do not have it. Router that features packet filtering is also called the packet-filtering routers. Router functions generally block traffic transmitted broadcast data so as to prevent a broadcast storm that can slow network performance.
Router is a tool in the computer world that is useful to deflect the data from a network system to another system. Logically a network system can not switch to another system. Sis A. Exp Using the IP 192.168.1.1 and Sis B. The Company uses IP 192.168.2.1 using Sis A can not communicate with Sis B without a Router.
Working principle of the router is very easy to deflect the data from one another Sis to Sis. For router configuration using a PC (OS WIN XP) is very easy:
1. Make sure your Company have a minimum of 2 pieces LAN Card (If you only use 2 Sis)
2. Give the network configuration according to Sis are you using on each LAN Card. (Make sure every lan using different Sis)
3. Ping or test the connection to each Sis, of the router. make sure all connections in a state of Good
