What is a WEP Key? WEP, which stands for Wired Equivalent Privacy, is a security algorithm used for IEEE 802.11 wireless routers. One of the problems that comes with using a wireless router is that you are transmitting your data by using waves rather than through wires. This means that the data can be picked up by another computer which is something known as eavesdropping. To prevent against this, WEP was implemented in 1997 to prevent this data from being intercepted and analyzed. WEP has since been replaced by WAP Read More

The arc transmitter is an instrument for converting direct current into Radio Frequency or (RF) energy. Prior to the development of the arc transmitter, wireless communications were built around the spark-gap transmitter which was inefficient (it wasted bandwidth and used up more energy than required), disruptive (the wide range of frequencies that spark-gap transmitters generated caused massive interference to other radio frequencies), and unstable. The arc transmitter (and later, the high-frequency alternator) was able to focus radio energy along a single frequency (or at least a very narrow frequency range Read More

Bootable antivirus software refers to any type of antivirus program that can be booted from a CD, DVD, or removable hard drive and can detect viruses on a user’s computer without having to startup Windows. Bootable antivirus software can be very important when a virus takes over a computer or prevents regular antivirus software from running. Bootable antivirus software is portable and usually does not need to be installed on the user’s computer. While bootable antivirus software can run outside of Windows and is often used in emergencies, it is Read More

An ad hoc network is a type of peer to peer wireless network mode where wireless devices communicate with each other directly, without the aid of a Wireless Access Point (WAP) device. Wireless networks typically depend on a base station or WAP device to manage and direct the stream of data between wireless devices. In an ad hoc setup, the network is built spontaneously as and when devices communicate with each other. These devices should ideally be within close range of each other; however quality of connection and speed of Read More

Understanding Document Specifications A document specification is theterminology used to signify a XML document that has been formally described. A document specification describes the records and fields in other documents. BizTalk Server only processes document specifications. The document specification describes relationships between different data items. This is done by organizing the items in a hierarchy. The document specification is actually a hierarchy of nodes with a root node at the top. The nodes beneath the root node can be records or fields. The lowest level of the hierarchy contains fields.

An ANAC number is a telephone number that plays back the number of the telephone that called it. ANAC numbers are convenient if you want to know the telephone number of a pair of wires. ANAC stands for Automatic Number Announcement Circuit. What is the ANAC number for my area? To find your ANAC number, look up your NPA (Area Code) and try the number listed for it. If that fails, try 1 plus the number listed for it. If that fails, try the common numbers like 311, 958 and Read More

Ethernet cable connects a network interface card (NIC) with a hub or Ethernet switch. Ethernet cables can be purchased from a computer store. They come in two categories, flat and braided. The flat or solid cable is used when there is a need for a longer cable run. However, it is not flexible. Thus, its position is fixed. The braided cable is easier to use and is more flexible. However, it is useful only in places where a shorter cable run is needed. In the Ethernet cable pinout there are Read More

We all use electronic devices, whether they are mobile phones, computer routers, MP3 players, cable boxes, etc. These electronic devices include hardware, the physical electronic components and software, programs that help these components run effectively. Firmware is a mix of both. Firmware Firmware is usually defined as a type of program that runs within an electronic device. Firmware is not categorized either as hardware or software, but a mix of both. The reason firmware is considered a combination of both categories is that firmware employs an executable program (.exe) and Read More

At its most general meaning, “binary” refers to any system composed of two elements. For example, a binary star system is a system in which there are two stars that orbit each other. Binary is also a numbering system that is comparable to our standard decimal system. The decimal system uses 10 digits; 0 through 9, and is referred to as a base-10 system. The binary system only has two digits, 0 and 1, so is referred to as a base-2 system. Binary in Computing Binary is essential to the Read More
