      UDP (User Datagram Protocol)

      User Datagram Protocol or UDP is part of the Internet Protocol suite. By using UDP, programs running on different computers on a network can send short messages known as Datagrams to one another. UDP can be used in networks where TCP is traditionally implemented, but unlike TCP, it does not guarantee reliability or correct data

      How Do ADSL Microfilters Work?

      ADSL Internet Access Asynchronous Digital Subscriber Line (ADSL) is a broadband Internet option that is commonly available in many locations. Asynchronous only means that the download speeds and the upload speeds are different (with the upload speeds usually being significantly lower) and provides a fast option to browse the web. Internet access through ADSL requires one

      FTP (File Transfer Protocol)

      FTP (File Transfer Protocol) is the generic term for a group of computer programs aimed at facilitating the transfer of files or data from one computer to another. It originated in the Massachusetts Institute of Technology (MIT) in the early 1970s when mainframes, dumb terminals and time-sharing were the standard. Although the FTP programs have

      802.1p

      802.1p is an IEEE standard that describes mechanisms to prioritize traffic and perform dynamic multicast filtering. Because of its support for priority specification, 802.1p is important for providing Quality of Service (QoS) for better reliability and quality. Quality of Service QoS is a mechanism that allows for better handling of data that passes over a

      WiFi Signal Strength Meter

      Windows and other operating systems have a WiFi signal strength meter, but this is usually basic software and does not really tell the user much about the wireless signal. Fortunately, there are many other programs that do the same thing, but show the user more details about the wireless connection. We will describe some of

      TCP Sequence Prediction Attack

      A TCP sequence prediction attack is an attempt to hijack an existing TCP session by injecting packets which pretend to come from one computer involved in the TCP session. The TCP Sequence Prediction Attack TCP is a reliable connection-oriented layer 4 (Transport Layer) protocol. Packet transfer between hosts is accomplished by the layers below layer
