Local Area Network

UDP is used for those applications that require speed, not quality of transmission. This would include streaming audio and video, and Voip. If you lose a packet or two it doesn't make a great deal of difference compared to file transfer protocol, where everything must arrive correctly.

These are called protocols - a standard set of rules for common communications across networks.

A rollover cable with a RJ-45 connector will plug into a console port on a Cisco device, the other end can be a DB-9 connector or another RJ-45 that can plug into an adapter.

It is more expensive and sophisticated as compared to a peer to peer network, can take more troubleshooting, and usually requires a dedicated network administrator which sufficient training to manage the network (comes down to cost).

Plus, the software to manage the network is more complex and can be more costly (in a non-open-systems area).

A Wide Area Network is a connection between two or more network LAN segments that are a distance apart, usually too far apart to be connected as just 1 LAN. They may connect networks in different cities, countries, etc., over a wide distance.

Where are they found? All over the world, wherever the connections on a wide distance are required.

• tracking transmitted data
• acknowledging received data
• Retransmitting acknowledge data

For an Ethernet network, each computer needs a network card and a network cable. You also need a switch - each computer will be connected to the switch.

For a wireless network, you don't need cables (that's the whole idea of wireless!), but each computer needs a wireless network card instead. Instead of the switch, you would use a wireless access point.

A host on a network is generally a device with a unique mac address (hardware address, set at the factory)

It can be a PC with a network device, a network switch, a printer etc etc

hosts can have an IP address mapped to their mac address's

Either...

A) Your computer isn't hooked up to a LAN or Cable Modem.

B) Your computer doesn't have a set internet preference (ic. Wireless/Airport, Ethernet, Cable modem etc) or

c) Your computer isn't internet ready, it would have to be ancient. xD

A) Lan Cable Meter

B) Multimeter

C) Plug it into a PC or laptop and try to connect to the internet

star topology,bus topology,ring topology,mesh topology etc...

Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP) are two very popular Distance Vector routing protocols

bus topology, ring topology

It's when you have to use a wire(s) to connect two computers.

a gateway can translate information between different networks data formats or network architecture. most gateways operate at the application layer. it can also be operated on network or session layer. by: talha jamal and farhan moin (kinpoe)

A network topology refers to the geometric arrangement of the actual physical organization of the computers (and other network devices) in a network. Network Topologies: Bus All devices connected to a central cable, called the bus or backbone. Bus networks are relatively inexpensive and easy to install for small networks. Star All devices are connected to a central device, called a hub. Star networks are relatively easy to install and manage, but bottlenecks can occur because all data must pass through the hub. Ring All devices are connected to one another in the shape of a closed loop, so that each device is connected directly to two other devices, one on either side of it. Ring topologies are relatively expensive and difficult to install, but they offer high bandwidth and span large distance. Hybrid Group of star-configured workstations are connected to a linear bus backbone cable, combining the characteristics of the bus and star topologies. Wireless Devices are connected by a receiver/transmitter to a special network interface card that transmits signals between a computer and a server, all within an acceptable transmission range.

We can extend LAN by using repeaters. If we increase LAN by using large number of repeaters than this arrangement does not guarantees sufficient signal strength. Each repeater and segment along the path increases the delay. If the delay becomes too large scheme fails. In fact, repeaters are part of the Ethernet standard, which specifies that the network will not operate correctly if more than four repeaters separate any pair of stations. i. If we can extend the LAN then why we need a WAN? ii. How can a bridge know whether to forward frames? iii. Can the length of an Ethernet be increased to many segments of 500 meter each merely by adding a repeater to connect each additional segment? iv. How can a computer attach to a network that sends and receives bits faster than the computer's CPU can handle them?

The submask indicates the division between the network id and the host information in an ipV4 address. The default subnet mask indicates the presence of a class A, B, or C based network (the default) without subnetting.

I think it is MAN (metropolitan area network)
