Local Area Network

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?

I think it is MAN (metropolitan area network)

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.

The benefits of being a computer networker include being able to work on your own network, work in advanced environments, and earn a respectable living. Those who are knowledgeable of networking often work for large companies which require constant network maintenance.

The technical specification for Cat5e specifies a total length of 100 meters (about 328 feet). This usually breaks down (during design) to 90 meters of 'structured cable' (cable that is permanently installed from one point to another) and ten meters (33 feet) of connecting cables for the ends. This isn't the complete answer however. The Cat 5e specification is less about length and more about performance. It's quite possible that a cable can be shorter than 100m and still not meet the Cat 5e standard. The most common cause is poor installation. A cable that bends too sharply deforms the wiring inside and can cause the signal sent on one wire to interfere with the signal on another. Cable that is not properly terminated can cause loss of data because of poor connections or wire to wire interference. On the other hand, if you simply ignore the arbitrary length limit and concentrate on proper installation methods, you can easily obtain Cat 5e PERFORMANCE well beyond the stated 100 meters.

An RJ45 connector has 8 conductors. it has the naming convention of 8P8C (8positions 8conductors).

Devices that separate work groups on a local area network (LAN) are called network switches. Switches manage data traffic by directing packets to specific devices based on their MAC addresses, effectively segmenting the network for improved performance and security. Additionally, virtual LANs (VLANs) can also be configured to logically separate different work groups within the same physical network.

A lan that is directly or indirectly controlled by a SERVER. In a server based lan, most workstations have to log into the server to gain access to the network.

All network devices have some component that operates at layer 1. Only hubs and repeaters operate entirely at layer 1.

The maximum allowed length of a Cat-6 cable is 100 meters (330 ft) when used for 10/100/1000baseT. This consists of 90 meters (300 ft) of solid "horizontal" cabling between the patch panel and the wall jack, plus 10 meters (33 ft) of stranded patch cable between each jack and the attached device. Since stranded cable has higher attenuation than solid cable, exceeding 10 meters of patch cabling will reduce the permissible length of horizontal cable.

When used for 10GbaseT, Cat-6 cable's maximum length is 55 meters (180 ft) in a favorable alien crosstalk environment, but only 37 meters (120 ft) in a hostile alien crosstalk environment such as when many cables are bundled together. 10GbaseT runs of up to 100 meters (330 ft) are permissible using Cat-6a.

TCP has no default port. Individual applications - such as FTP, DNS, or Telnet - do have default ports.
