With fast-access computers and interlinking networks that connect many different devices together, many users worry about other people stumbling upon their personal information. With the dangers of the Internet aside, users still have to be concerned about their friends, relatives, and co-workers accessing their computer and seeing things that they would rather keep private. Because of this, there are dozens of programs available that are able to protect users' files and folders with a password and various encryption methods. This article will explain what encryption software is and list a Read More

Westell is a provider of DSL routers and other DSL-based devices that telephone companies and DSL subscribers use for wireless Internet in homes or offices, instead of using cable or satellite Internet. Westell products generally have the same features as other routers, such as dual antennas, four Ethernet ports, and WPA encryption, but connect to the Internet through a telephone wire. The Westell wireless router has been used since mid-2004 as BellSouth’s default Internet router. The router features 802.11 wireless support, four Ethernet ports, and a built-in firewall.

To receive all of the DirecTV HD channels you must have, at minumum, a triple LNB that receives transmissions from the DirecTV satellites at 101, 110 and 119 degrees West longitude. The DirecTV satellite dishes which support the triple LNB include: DirecTV Phase II Plus Dish DirecTV Phase III Dish Alternative, for future compatability with DirecTV’s new Ka Band MPEG-4 HD programming, you can use the AT9 MPEG-4 Compatible Ku/Ka Band dish with five LNBs. With an older satellite dish with only one or two LNB’s, you will be able Read More

Bluetooth is a wireless communication protocol which is used to exchange information or data over short distances, with the help of fixed or mobile devices. Bluetooth wireless technology is integrated into these kinds of electronic devices to enable users to exchange information such as music, videos, and pictures wirelessly. Bluetooth technology was created in 1994 by engineers working at Ericsson, Sweden. The Bluetooth Special Interest Group was formed in 1998 by various companies to develop, maintain, and license Bluetooth standards. Bluetooth is implemented with the help of a radio technology Read More

If you want to add a printer to a wireless network, you need to: 1) Ensure that the printer has at least one USB port. 2) Purchase a wireless adapter and connect it to the printer’s USB port. Since wireless adapters work on Plug-and-Play technology, the printer should automatically detect it and begin installing all of the drivers necessary for the wireless adapter to function properly. 3) In order to specify which wireless network the printer should connect to, connect the printer to the router via an Ethernet cable and Read More

A dielectric is a material that restricts the flow of current. Dielectrics are defined by their dielectric constant, current leakage, and breakdown voltage. They are mainly used in capacitors, allowing charge to build up on the conductive plates. An insulator is a dielectric than can withstand a high electric field without letting current flow through it. Permittivity When the material is surrounded by an electrostatic field, the electrons in each atom shift towards the positive side and away from the nucleus. This creates a dipole moment in the atom and Read More

What is Authentication Authentication is the process whereby the system identifies legitimate users from unauthorized users. It is the process in which a user identifies his/her self to the system. How effective an authentication process is, is determined by the authentication protocols and mechanisms being used. Windows Server 2003 provides a few different authentication types which can be used to verify the identities of network users, including: Kerberos authentication protocol NT LAN Manager (NTLM) authentication protocol Secure Sockets Layer/Transport Security Layer (SSL/TLS) Digest authentication Smart cards Virtual Private Networking (VPN) Read More

High-Bandwidth Digital Content Protection, also known as HDCP, is a newer form of Digital Rights Management (DRM) that was designed to control digital video and audio content. The technology was originally created by Intel to ensure that digital audio and video travelling across a Digital Video Interface (DVI) or High-Definition Multimedia Interface (HDMI) would follow the various guidelines put forth by the Digital Content Protection group. What Is Required Of An HDCP Capable Device In order for a product to claim that it is HDCP capable, it must have a Read More

Satellite radio refers to a number of subscription-based radio broadcasting programs that are available in the US, Europe, and elsewhere that are dependent on satellites to provide mobile users with constant radio access. While terrestrial-based FM radio stations only provide radio broadcasts to a specific area, usually confined to the city they are located in, satellite radio is available even while the listener is moving between cities, states, and even countries. Satellite radio has been available for just over a decade, with the first artist ever broadcasted on satellite radio Read More

A rollover cable is a network cable that connects a computer terminal to a network router’s console port. It is also referred to as a Cisco console cable and is normally flat and light blue so as to distinguish it from other network cable types. The pin-outs on one end of the cable are reversed from the opposite end, which is how the cable derived its name. Rollover cables are also known as Yost cables or Yost Serial Device Wiring Standard connectors. How to Identify a Rollover Cable A rollover Read More
