Network Routers
A network router is a network device with interfaces in multiple networks whose task is to copy packets from one network to another.
Routers operate at Layer 3 of the OSI Model, the Network Layer. This is in contrast to switches, which operate at Layer 2 of the OSI Model, the Data-Link Layer.
A network router will typically utilize one or more routing protocols, such as RIP, OSPF, or BGP. Routers also accept routes which are configured manually by a network administrator. Those routes are called static routes.
The router will use this information to create a routing table.
The network router will then use its routing table to make intelligent decisions about which packets to copy to which of its interfaces.
This process is known as routing.
Routers are available with many types of interfaces, such as Ethernet and DSL. Wireless routers support wireless interfaces, such as 802.11 (Wi-Fi).
Routing software makes it possible to build a fully functional router out of a normal computer.

- Types of Network Hardware
The label network hardware is generally given to any piece of equipment with the task of moving data. Common categories of network hardware include: Routers Switches Network Interface Cards Routers A router is a network device with interfaces in multiple networks whose task is to copy packets from one network [...]...
- Wireless Routers
A wireless router is simply a router with a wireless interface that incorporates a wireless access point’s utilities. It is generally used to permit access to the Internet or a local computer network without using a wired connection. It can work in a cabled LAN (local area network), only wireless network, or a combination of [...]...
- Network Layer
The Network Layer is located at the 3rd position in the seven layer OSI model. It offers serviceable and practical ways of transmitting variable length data series from a source to a destination through one or more networks, while preserving the class of service and error handling tasks. The Network Layer is accountable for source [...]...
- Routing Table
A routing table is an electronic document that stores the routes to the various nodes in a computer network. The nodes may be any kind of electronic device connected to the network. The Routing Table is usually stored in a router or networked computer in the form of a database or file. When data needs [...]...
- Routing Protocols
A routing protocol is the implementation of a routing algorithm in software or hardware. A routing protocol uses metrics to determine which path to utilize to transmit a packet across an internetwork. The metrics that routing protocols use include: Number of network layer devices along the path (hop count) Bandwidth Delay Load MTU Cost Routing [...]...
Where do i get my wireless network name and key so, i can use my laptop?
You can see them in your router’s wireless settings or if you have another computer in which wireless already works you should be able to scoop it from its settings.
To access wireless settings of your router you have to connect to it through your browser, usually at 192.168.1.1. You’ll need your router password. If you never set one it should be the default (for linksys username is blank and password is “admin”, check the manuals for others).
how can i change the password of wifi ?
