Broadband is a term that is used consistently with different types of Internet connections. Generally, it is referred to Internet connections over fiber optic cables rather than telephone lines. Broadband in telecommunications means a wide range of frequencies that are available to transmit information. This eventually means that, wider the range of frequencies available, higher the amount of information that can be sent at any given point of time. For an easy way to picture a broadband Internet connection compared to a narrowband Internet connection, think of a road highway. Read More

NetBEUI (NetBIOS Extended User Interface) is an extended version of NetBIOS, the primary software that allows individual computers to communicate within a given local area network. While NetBIOS itself is most often used to transfer pictures, documents, videos, or other files from one computer to another, NetBEUI is responsible for arranging the actual information in a data transmission. As a result, NetBIOS cannot transfer files or share access rights between two computers without the NetBEUI extension. How NetBEUI Works NetBEUI is neither its own stand-alone program nor its own protocol. Read More

A VoIP Gateway (Voice over IP Gateway) is a network device that helps to convert voice and fax calls between an IP network and Public Switched Telephone Network (PSTN) in real time. It is a high performance gateway designed for Voice over IP applications. A VoIP gateway can typically support at least two T1/E1 digital channels. Most VoIP gateways feature at least one Ethernet and telephone port. Various protocols, such as MGCP, SIP, or LTP can help to control a gateway. VoIP Gateway Benefits VoIP gateway’s main advantage is that Read More

Quick sort is a divide-and-conquer sorting algorithm. To understand quick-sort, let us look at a high-level description of the algorithm. Divide: If the sequence S has 2 or more elements, select an element x from S to be your pivot. Any arbitrary element, like the last, will do. Remove all the elements of S and divide them into 3 sequences: L, which holds S’s elements less than x E, which holds S’s elements equal to x G, which holds S’s elements greater than x Recurse: Recursively sort L and G Read More

Planning the Test Network Environment Any successful network design deployment includes a testing strategy, and the execution of the testing plan. To test the network design, you have to plan the test network or environment, and then create the test network. A testing environment can contain one lab or multiple labs. You can build various labs to test specific components within the network design. When planning your test environment, take time to create an environment that can prove whether or not the network design being tested is effective. You should Read More

A packet and a frame are both packages of data moving through a network. A packet exists at Layer 3 of the OSI Model, whereas a frame exists at Layer 2 of the OSI Model. Layer 2 is the Data Link Layer. The best known Data Link Layer protocol is Ethernet. Layer 3 is the Network Layer. The best know Network Layer protocol is IP (Internet Protocol). To move through a network, a packet is encapsulated into one or more frames, depending upon the MTU size.

An Internet Bot is a software application that does repetitive and automated tasks in the Internet that would otherwise take humans a long time to do. The most common Internet bots are the spider bots which are used for web server analyses and file data gathering. Bots are also used to provide the required higher response rate for some online services like online auctions and online gaming. Web interface programs like instant messaging and Internet chat relay applications can also be used by Internet bots to provide automated responses to Read More

Cadmium Telluride is one of the most toxic and deadly substances known to man. It is a by-product of lead, zinc, and copper mining and is also naturally found in soil and water. Despite its toxicity, cadmium telluride is still frequently used because it has highly sought after physical and chemical properties. What Are the Properties of Cadmium Telluride? Cadmium telluride has a high resistance to chemicals and corrosion as well as a high tolerance for extreme temperatures. The substance also has a low melting point and is considered an Read More

The exercise of upgrading the memory of your computer is often the chief means of achieving a boost in performance. Upgrading of the RAM, or Random Access Memory as it is called, is necessary to keep pace with the resource hogging needs of new software. The easy-to-follow tips and directions in this article should help you accomplish the task. Determining the amount of main memory you need One gigabyte of RAM is usually suggested to average users running Windows XP. However, many users prefer to go for 2 GB or Read More

Electric field strength refers to the intensity of an electric field and is a measurement of the amount of energy present in an electric field. Electric field strength plays a major role in power grids, electronic equipment, electromagnetic devices, and a variety of other electrical systems. This is because devices must be able to calculate how much electricity is coming into the system, how much electricity is being directed towards a specific function, and how much electricity each function requires in order to safely power a wide variety of appliances.
