The router is a computer networking device that sends data packets through a network or the Internet to the destination, through a process known as routing. Routing occurs at layer 3 (network layer such as the Internet Protocol) protocol stack of the OSI seven-layer.
Function
The router serves as a liaison between two or more networks to carry data from one network to another. Different routers with switches. Switch is a connecting multiple devices to form a Local Area Network (LAN).
Analogy Router and Switch
As an illustration of the different functions of routers and switches is a street, and the router is the link between road. Each house is on the road that has an address in a particular order. In the same way, a switch connects various devices, wherein each device has its own IP address on a LAN.
Router is widely used 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. Router can be used to connect multiple smaller networks into a larger network, called the internetwork, or to divide a large network into several subnetworks to improve performance and simplify management. The router is also sometimes used to mengoneksikan two networks that use different media (such as a wireless router in general than he can connect a computer with a radio, it also supports connecting a computer with UTP cable), or different network architectures, as well as from Ethernet to Token Ring.
The router can also be used to connect LANs to a telecommunications service as well as leased telecom 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 referred to as a DSL router. Routers of that type 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 a packet-filtering router. Routers are generally block traffic transmitted broadcast data so as to prevent a broadcast storm that can slow network performance.
The types of router
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 set manually by the network administrator.
dynamic router (dynamic router) is a router that has a dab makes dynamic routing tables, by listening to network traffic and also to interact with other routers.
Bridge versus Router
How it works similar to a bridge router network, which they can forward the data packet network and can also divide a network into multiple segments or network segments together. However, the router runs in the third layer of the OSI model (network layer), and use the addressing scheme used on that layer, as well as IP addresses. Meanwhile, the bridge network is running on a second layer of the OSI model (data-link layer), and use the addressing scheme used on that layer, the MAC address.
Then, when using bridged networking done and when the use of router do? Bridge, should be used to connect network segments that run the same network protocol (for example: IP-based network segments with other segments of the IP network). In addition, the bridge can also be used when there are in the network protocols that can not perform routing, such as NetBEUI. Meanwhile, the router should be used to connect network segments running berebeda network protocols (such as to connect the IP network segments with IPX network segment.) In general, the router is more intelligent than the bridge network and can increase network bandwidth, given routers not forward broadcast packets to the destination network. And, the use of routers is most often done when we want to connect our network to the Internet.

Gateway is a device used to connect a computer network with one or more computer networks that use different communications protocols so that information from a computer network can be provided to any other computer network protocol is different. The definition is the definition of the main gateway.
Along with the proliferation of internet, definition of gateway is often shifted. Also for the beginner to equate "gateway" to the "router" is actually not true.
Sometimes, the word "gateway" is used for connecting devices mendeskripkan large computer networks with other large computer networks. This is often the difference arises because the communication protocols in computer networks occurs only at the level of large computer networks.
