Local Area Network

In Information Technology- A network is a group of computers that both share and receive data from one another. A really good example of this is the internet. One official definition of the word network is "a group or system of interconnected people or things."

ATM has (i) Fixed cell size, (ii) Implemented to meet the transport requirements for LAN,MAN and WAN applications, (iii) Connection-oriented, (iV) Cell size is fixed and is of 53 bytes 5 for header and 48 for payload, (V) Packet switching on private network that operate on data link layer on OSI.

Whereas IP has (i) Variable cell size, (ii) Allow voice, data, fax and video signals to share a common networking infrastructure, (iii) Connection less, (iV) Cell size is upto 65535 bytes,and (V) Network addressing that operate on network layer on OSI frame relay.

You use a tunneling protocol when you want to preserve confidentiality in information that is being sent across a network. This way listeners cannot understand the information.

Transmission time is the time it takes a message to reach its destination from is source. It is the time between the first bit leaving the sender and the last bit arriving the receiver. The first bit leaves earlier and arrives earlier; the last bit leaves later and arrives later. The time required for transmission of a message depends on the size of the message and the bandwidth of the channel.

IP address is categorized into IPv4 and IPv6. The IP is valid only if it is in the range of IP address range class.

If you question whether or not the IP is really that of a safe site, you can do an IP lookup using an IP lookup tool. They are available free and can be found by doing a search using the term "IP lookup."

The LANs themselves are no different depending on the number of hops. The number of hops to get to another LAN is based on the number of other routers the packet must pass through to get there. The LANs don't care about the difference between a single and a multiple hop.

The server knows by the destination port number, which attaches a listening program to a specific protocol.

I believe string length and cable length aren't 2 different things

If the client doesn't know the IP address of the desired web server it has to find that out. This can be done via DNS if you know the name of the server as part of the URL.

After the address is located then transfer takes place using HTTP protocol. This is a layer 7 (application layer) protocol.

There are a number of technical differences, involving the number of twists per inch on the conductors, the capacitance per linear foot between members of a pair and between pairs, and in the propagation speed of electricity along the cable. In practical terms, the category determines the fastest network that can use the cable at full speed.

Category 3 cable was originally used for telephone lines. It can be used with 10BaseT networks, twisted pair with a highest speed of 10 megabits per second (10Mb/s).

Category 5 cable has a guaranteed number of twists per inch on the two pairs (of four) that actually carry the data. It is rated to carry data on 100BaseT networks, up to 100Mb/s.

Category 5e cable has a slightly lower capacitance per linear foot, which results in its being able to handle data speeds up to 300Mb/s, and larger packets on 100Mb/s networks. It can be used on 1000BaseT networks, but most such networks will detect the lower-spec cable and derate themselves to 300Mb/s, and sometimes disable "jumbo packets", as the network hardware determines that the cable can't carry data at speed without corruption.

Category 6 cable has a higher number of twists per inch on all pairs, and a lower per-foot capacitance rating. It is able to carry data on 1000Base-T networks, up to 1000Mb/s, or one gigabit per second (1Gb/s).

There is, at this writing, no formal specification for Category 7 cable. In theory, it should be able to support 10,000BaseT, 10000Mb/s, 10Gb/s. However, there are few networks available yet that put 10Gb/s on copper, and there does not yet seem to be a standard for what sort of cables are needed to handle that data speed reliably.

The Transport layer (layer 4) handles segmentation and reassembly of the data.

A contention-based protocol (CBP) is a communications protocol for operating wireless telecommunication equipment that allows many users to use the same radio channel without pre-coordination. The "listen before talk" operating procedure in IEEE 802.11 is the most well known contention-based protocol.
