Computer Networking

TCP is a connection-oriented protocol whereas UDP is a connectionless protocol.

TCP ensures data integrity and reliability. TCP is prefered when important data must be sent and verified that it arrived correctly and is most desirable in conditions that promote data corruption or loss. If a packet is lost or corrupt, TCP will automatically resend the packet and wait for a confirmation message back. TCP would be used in senarios such as transfering files, surfing a webpage, or listening to pre-recorded on-demand music or video.

UDP is a fast, efficient protocol with low overhead that offers no redundancy to lost or corrupt packets. If a packet is lost or corrupt, the data is lost and no attempt is made to resend the information. UDP is prefered for streaming audio and/or video live such as Voice over IP phones, watching internet TV, or listening to internet radio.

Yes you can set up a WEP on any router, but WEP is not very secure.
WPA and WPA 2 would be a better way to go.

nodes often change their location within network. so, some stale routes are generated in the routing table which leads to unnecessary routing overhead.

Power Line ethernet is a network adapter, It connects to an electrical component in one room but allows for another room to use the power without having to connect to the main source through an ethernet cable. By doing this, it cuts down on many cables having to be run from the main electrical source to users of that source.

The precursor to Wi-Fi was invented in 1991 by NCR Corporation/AT&T (later Lucent & Agere Systems) in Nieuwegein, the Netherlands. It was initially intended for cashier systems; the first wireless products were brought on the market under the name WaveLAN with speeds of 1 Mbit/s to 2 Mbit/s. Vic Hayes, who held the chair of IEEE 802.11 for 10 years and has been named the 'father of Wi-Fi,' was involved in designing standards such as IEEE 802.11b, 802.11a and 802.11g.

DNS configuration stands for Domain Name System Configuration. It is a system in place for any computers connected via network whether private or on the internet. It allows for converting IP addresses to names. DNS is like the phone book of IP addresses.

try installing anti virus software onto your comupter. then running a scan and removing the virus if there is one. if not there may be a problem with the internet explorer installed on that computer try redownlading internet explorer then reinstalling it. if all else fails take it into a computer repair shop.

The ISP is what gives your router its internet connection. You can't bypass the ISP any more than you can bypass the power utility company in getting electricity - you can switch provider or "borrow" from your neighbour, but you need to get it from somewhere.

First of reboot your computer, second try to update the driver for your wireless adapter. Also make sure that you are allowed to connect to those findable networks. If you can see the networks it does not mean that you can connect to it. Many people use secured wireless networks which protects networks from unauthorized access.
