Wireless security is another aspect of computer security. Organizations may be particularly vulnerable to security breaches [6] caused by rogue access points.. If an employee adds a wireless interface to an unsecured port of a system, they may create a breach in network security that would allow access to confidential materials.
A MAC address (short for medium access control address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.
In geometry, a point is an abstract idealization of an exact position, without size, in physical space, [1] or its generalization to other kinds of mathematical spaces.As zero-dimensional objects, points are usually taken to be the fundamental indivisible elements comprising the space, of which one-dimensional curves, two-dimensional surfaces, and higher-dimensional objects consist; conversely ...
At one point, Microsoft was also interested in Excite, and had plans to merge it into its own MSN portal. [ 14 ] According to Steven Levy in his book In The Plex , [ 15 ] in early 1997 two graduate students at Stanford University , Sergey Brin and Larry Page , decided that BackRub, the name of their research project that later became the search ...
Carrier-sense multiple access with collision avoidance (CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be "idle". [1] [2] When they do transmit, nodes transmit their packet data in its entirety.
AOL Mail offers a free, secure and beautifully designed email experience with standard mailbox features.
Often the point to multipoint links are installed to reduce the cost of infrastructure and increase the number of CPE's and connectivity. [2] Point-to-multipoint wireless networks employing directional antennas are affected by the hidden node problem (also called hidden terminal) in case they employ a CSMA/CA medium access control protocol. The ...
