Local Area Network

HTTP transfers data from a web server to a client

Telnet provides a virtual connection for remote access

ip address is basically the address of your internet connection, like a=each and every house is registered with the government and the address is known,

likewise, your internet connection is registered with your ISP(internet service provider).

ip address can be either static or dynamic, like the words suggest,

static ip address will remain the same whereas dynamic ips will change from time to time(each time you connect).

there are ways to change your ip address, which require software, but its only needed by hackers or crackers..... you wont be needing it.....

Usually its port 21. Though alot of people fail to realise that just because that's the default setting doesn't mean you cant change it.

FTP servers listen on port 21. The data transfers happen on a different port, which is usually done in passive mode, on a port above 1024.

The process of planning a local area network, including (but not limited to), IP address space (# of hosts), media used, topology, etc.

Telnet use port number 23,and connected to TCP

A switching power supply adapter from Dee Van Electronics.

In space division switching,there is a dedicated path established between the callin and called subscribers for the entire duration of call.This meams the speech siganls are transferred between them in the duration.The time format of T1 or E1,the PCM samples occurs at 125 microsecond.Now the dedicated switching elements remains unsed for almost 120 microseconds.This the defect of space division switching.

In terms of architecture, crossbars,matrix,contact everything are placed separetly in the board

It consists of a few minicomputers interconnected by a communication network.Each minicomputer usually has multiple users logged on to it simultaneously.For this several interactive terminals are connected to each minicomputer.Each user is logged onto one minicomputer,with remote access to other minicomputers.The network allows the user to access remote resources that are available on some machine other than the user is currently logged.Minicomputer model can be used for resource sharing like information databases.

You need to look up QoS (quality of service).

The single most important reason for using encryption is to preserve confidentiality. This means that only an authorized receiver can read the message (the receiver must have the appropriate decryption key).

The disadvantage is the overhead it takes to encrypt and decrypt the messages, especially if a digital certificate is involved, because it may have to be authenticated as well, and that takes time.

Just add a network interface card, the TCP/IP protocol in Network Connections and connect to a router or cable modem. That's the simple answer. The process could be a little more difficult depending on your circumstances and computer's hardware configuration.

GPS: global positioning system

Yes, you can. WINS was designed to speed up information flow about the Windows workstations in a network. It will work without it, and most networks do not utilize WINS servers anymore because it is based on an old protocol (NetBUI) which is no longer in common use.

An onboard LAN is a built-in ethernet adapter on mother board, if you have an onboard LAN, then, there is no need to install another ethernet card for your purpose.

Use a "whois" search.

Cross-bench peers are peers appointed to the House of Lords not to support a political party, but to add their specialist knowledge or expertise. They sit on the cross bench, not on the party benches, and are not subject to the party whip. The Law Lords are included in the cross-bench peers. Full information is available at the web site of the House of Lords.

The distance between two operating computers have no effect on each other. Unlike many electronic devices, computers towers themselves do not emit enough electro magnetic interference to cause harm to anything surrounding it. CRT monitors, however, can affect each other. When turning on a CRT that is closely positioned to another monitor, the second one will shake and flicker until the first one is fully on. This is only temporary because of its EMI. LCD monitors do not have this affect, nor are affected.

Concerning the network - there are no affects of cross talk between two computers that may harm information on the network lines.

Probably the best thing to do is for management to make sure there are no false rumors that get around, because this causes excitement and/or aggression among the employees involved. Communication should not be gossipy and should probably relate to the organization itself.

Data Link Layer

By getting yourself a good switch and a good reliable OS on your server and watch out for older computers with crap network cards. If you want optimal performance you will have to spend abit of money on buying good parts. I find these few things cause the most bottlenecks in alot off small networks.

Simply a novel can be defined as it is a long narrative piece of literature or long narrative writing but in prose form

Computer network Polling is where a client server or Network Hub polls each computer for data. Data can only be sent when the particular computer is polled. If the computer has data to send but is not polled at that time, the data has to be stored until it can be sent. ^_^ JunkCollector ^_^

Collision hardly takes place in todays intelligent switches. According to my knowledge all swicthes in todays era are working on CSMA-CD i.e. Carrier Sense multiple access - collision detection. Every station in a network sense the carrier so the switch before maintaining any communication.

* The main goal of networking is "Resource sharing", and it is to make all programs, data and equipment available to anyone on the network with out the regard to the physical location of the resource and the user. * A second goal is to provide high reliablity by having alternative sources of supply. For example, all files could be replicatied on two or three machines, so if one of them is unavailable, the other copies could be available. * Another goal is saving money. Small computers have a much better price/performance ratio than larger ones. Mainframes are roughly a factor of ten times faster than the fastest single chip microprocessors, but they cost thousand times more. This imbalance has caused many system designers to build systems consisting of powerful personal computers, one per user, with data kept on one or more shared file server machines. This goal leads to networks with many computers located in the same building. Such a network is called a LAN(local area network). * Another closely related goal is to increase the systems perfomance as the work load increases by just adding more processors. With central mainframes, when the system is full, it must be replaced by a larger one, usually at great expense and with even greater disruption to the users. * Computer networks provide a powerful communication medium. A file that was updated/modified on a network, can be seen by the other users on the network immediately. # Access to remote programs. # Access to remote databases. # Value-added communication facilities. Calling up a distant computer via a network is cheaper than calling it directly. The lower rate is possible because in a normal telephone call ties up an expensive, dedicated circuit for the duration of the call, whereas access via a network ties up long-distance lines only while data are actually being transmitted.
