In a star topology, each device connects to a central network connectivity device such as a hub, switch, or router. These devices would be connected as a "star" (points on a star).

The other characteristic of a star topology is that a failing connection will only affect the failed device unless that device is the connectivity device. This means that in most cases a failing device on a star will not take down the entire network.

Another characteristic of a star is that they are easily expandable and scalable.

As far as i know its port number 80 being used by all the HTTP sites including youtube.

The top most layer is the application layer and bottom most layer is the physical layer. Since data is transferred from top to bottom, I would say that the starting layer is the application layer.

255.255.255.0

That would be a class E network, E networks do not have defines subnet masks or networks. Just a range (240.0.0.0 - 255.255.255.255).

In very simple words, A leased line is a rent paying line; as the name suggests.

As it is very difficult to connect two different point in far flange areas, a customer uses a line that is provided by some network provider and pays accordingly.You can take it as connecting some of your database in two different cities.

Hope, you understand me :)

LAN stands for Local Area Network. It like an office with all the computers hooked so they can share data and send emails just inside the office or building. A WAN stands for Wide Area Network and it connects two or more LANs...the Internet is a good of example of a WAN...the internet consists of a network connected to other networks..hope this helps.

A repeater. Repeaters work only on layer 1 (Physical) of the OSI model.

If you look at redundant networks in nature, like the network of the veins within a leaf you may realize that redundancy creates resilience.

Often leaves are subjected to parasites or physical damage. If a vital vein is struck in a network without redundancy it would mean all tissues or nodes which it previously fed into would be effectively annihilated from the network (death). A redundant network overcomes this problem by spreading out the risk.

From a Computational standpoint this would be the same problem. Often critical layers of a network if left without connectivity would create critical failures for parts of the network which may be dependent on its activity. Such is the nature of hierarchy.

False - a peer-to-peer network is simpler.

A packet capture (or sniffer) program sees packets coming into and out of the NIC (network interface card). It saves it for later analysis and use. These capture programs can be used to analyze traffic, look for problems, or be used for looking at data coming across the network.

1 Gbps

That depends on what you will be using the cable for.

In general, the higher the frequency of the signal being sent down the cable, the shorter the cable has to be.

The environment of the cable is also important. If the cable is in an electrically noisy environment, it needs to be shorter.

There are various standards that specify the maximum length of a cable. Sometimes it will work (some of the time) if you use a longer piece of cable, but following the standard is much more likely to work correctly all the time.

Some examples from computer networking standars:

For 10BASE-T Ethernet, the maximum length of a cable is 100 meters. Note that this standard was defined for Cat 3 cable, so you'll probably be able to use Cat 5e cable to send the signal further. However, there's no standard specifying how much further - you'll probably have to test it yourself.

For 100BASE-T Ethernet, the maximum length is also 100 meters, but the cable grade is specified as Cat 5 (not Cat 5e). So you might be able to make a longer run work with Cat 5e.

For 1000BASE-T Ethernet, again the maximum length is 100 meters, but now the cable must be Cat 5e. Also, all four pairs of the cable are used, whereas in the other two standards only two pairs are used.

You should be able to do that, but some minor tweaking of setting might be required.

Go to the Wiki for OSI model -that discussion and listing is very good.

The 45 indicates the jack number; RJ45 indicates Registered Jack number 45. However, there is a slight complication - what most people call RJ45 should actually be 8P8C. The RJ numbers used to be allocated by the FCC, but they are now defined by Administrative Council for Terminal Attachment (ACTA).

LAN: Local Area Network

Examples:

1) 2 or more computers connected

2) small office or an internet cafe

WAN: Wide Area Network

Examples:

1) Internet

2) VPN

3) WAN links

why the lan high speed than wan

They forward only changes to individual routes instead of forwarding entire routing tables., taking up less band and time. Joseph G.

Examples for Metropolitan area network is a network of fire station, newspaper/media company, a chain of community colleges
