Definitions Integrated Services Digital Network (ISDN): ISDN is a digital transmission system, which is used to transmit voice and data through copper telephone wires. In other words, it's a circuit-switched data transmission system that is used for voice and data transmission over the wire. Digital Subscriber Line (DSL): DSL is also a digital transmission system …
Two of the most popular technologies that offer speedy access to the World Wide Web are DSL broadband and the cable modem. There are several reasons why this is the case and the first one is that both of these Internet connections are considerably faster than the standard dialup connections. However, when you compare the …
A dial-up connection is any connection that is connected through a regular phone line. When that phone line is connected to a modem and then configured to dial a specific number, a user can access the Internet. It is the slowest form of Internet connection, but that is a result of also being the most …
ISDN 30 is a type of Integrated Service Digital Network system that is used for the transmission of voice and data over wires. ISDN 30 is one of the most economical and efficient communication systems. It is used in medium as well as large businesses. Through ISDN 30, business organizations and call centers can get …
Every Ethernet card had a factory assigned MAC address burned into it when it was made. At times, users may want to change this MAC address to one of their choice. One of the main reasons for doing this is to get around access control lists(s) on a specific router or server, either by hiding …
PPP (Point-to-Point Protocol) is the most widely used method for transporting IP packets over a serial link between the user and the Internet Service Provider (ISP). Although PPP is primarily used over dialup lines, variants such as PPoE (PPP over Ethernet) and PPoA (PPP over ATM) extend PPP to new data-link layer protocols. PPP was …
For any two devices to be connected, they need a common place, or a hub, as it is called in the computer world. It basically connects multiple computers together. Most of the hubs available in the market today support Ethernet standards. This is why they are called Ethernet hubs, and are most commonly used in …
ISDN BRI (Basic Rate Interface) is a standard Integrated Services Digital Network (ISDN) service meant for residential and small scale business Internet connections. There is another type of ISDN configuration called the Primary Rate Interface (PRI) that is designed to provide higher bandwidth. The BRI configuration defined in the physical layer standard I.430 produced by …
A MAC address is an address that exists on Layer 2 of the OSI Model. Layer 2 of the OSI model is the Data Link Layer. The Data Link Layer consists of two sublayers, the Media Access Control (MAC) layer and the Logical Link Control (LLC) layer. The MAC sublayer controls how a network node …
ADSL (Asymmetric Digital Subscriber Line) options are available in many locations. The speeds will vary for the service in many ways depending on several factors. The reason why it is called an Asymmetric Digital Subscriber Line is simple, as the speed for downloads will be significantly faster than the upload speed. This is because consumer DSL services are …
