Computer Networking

TFTP (Trivial File Transfer Protocol) is a lightweight file transfer protocol that is most commonly used for booting computers over a network or updating devices attached to the network.

Throughput in megabits per second will always be equal to or less than the bandwidth in megabits per second (it can't be higher). Throughput decreases as latency increases. For instance if you send a file to your neighbor two houses down the latency should be very low (assuming you are on the same network). However, if you send it to another city the latency will be higher and while your bandwidth remains the same, your throughput will decrease due to the latency between the locations. Note that this can be improved by optimizing the TCP window size on your computers. There is a free TCP optimizer program available on the web if you search on that term.

The difference is that the write mem command is being discontinued. It is being replaced by the copy command and is the one you should use on the cisco tests. I still use this command on some routers such as 831, 871, 3002, 2950, 2600 however it appears that as of IOS 12 it will be gone.

Hope this helps!

Ports are devices used to connect a personal computer(PC) to external devices,such as keyboards and mice.They are located at the back of the PC.But today,some ports are found on the front of the PC as well.

The abbreviation of STCP is a computer term. This abbreviation stands for Stream Control Transmission Protocol and is used in networking.

You have problems either with network connection, proxy server if you have any, or firewall. Also in can your network card which is actually the worst case.

To make it secure you have to use encryption which is available in almost all routers.

LAN (Local area network) connects devices (computers) that are within a relatively small geographical are like a room or a building. The most popular connection technology for LANs is Ethernet.

There are millions of types of different networks in the world. These networks may be as simple as a computer network for example.

CLASS A - 1-126 (10.0.0.0) 1 n/w, 3 host CLASS B - 128-191 (172.16.0.0) 2 n/w, 2 host CLASS C - 192- 223 (192.168.0.0) 3 n/w, 1 host CLASS D - 224-239 CLASS E - 240- 254

A firewall is a combination of software and hardware that helps prevent unauthorized access to a system through the Internet. Modern Windows OS's feature an inbuilt firewall.

It depends on the type of LAN; the most common cable in a LAN is UTP cable. In older LAN types you could also use coaxial copper cable.

For UTP cable that would be Cat 5, cat 5E or above for most LANs.

Originally referred to as KVS ( keyboard video switch), the KVM began circulation during 1980's. While the name behind the hardware is unknown. Its purpose to illuminate congested computer stock rooms has proven successful.

For master degree program you must have to passed and certified yourself for getting certification exams like Microsoft, Apple, CompTIA, VMware, SISCO etc. I give you the direct link access to site where you can easily get all exam dumps material in a very cheap rates and started your preparation with in few day's.

You have to check you firewall, if you have it. And check the router settings. It might be the router fault. Sometimes people set up IP filters, you have to check it also.

Put simply, yes it will.

A server computer serves other computers (in a network) with programs and/or files. Think of it like a cafeteria. You get your tray (computer), walk down the line (pull down the file menu), when you see something you need or want you ask for it to be put on your tray (downloaded to your desktop computer). Your desktop computer is the same as a personal computer.

"Dot gov" refers to how you spell the Web site ending ".gov" as in "whitehouse.gov" or "senate.gov."

Every page is stored in the web in the hyper text format.. They are present in a tree structure of similar domain.. URL address refers to the traversal of a particular page present in the web and the path name of the page.

Without the following information being provided a person will not know what the correct answer is. It is important to also include what the following key elements are.

If the messaging is done Peer to Peer, but there is a server which helps the peers to find each other by registering themselves on it, it is then a hybrid relationship.
