In terms of internet connection, Cable is using the cable company’s infrastructure to bring data from the internet to your home, typically shared between a regional group of subscribers.

Client Manager:

Software that is used to configure wireless communications between two devices. Controls encryption and authentication settings. Windows XP has built-in software for these other operating systems that require a simple install.

Device Drivers:

Software that tells your computer how it is going to communicate with the hardware that’s connected to it. Usually comes on a disc with the hardware and vendors have updates available for better performance.


Dynamic Host Control Protocol is the technology used to automatically assign IP addresses to all the computers on a network and make sure each one is different. Usually set to automatic on a home network, unless you need a static address that never changes.


Domain Name System is the technology used on the internet to change a computer’s IP address into an alphabet name, which makes them easier to understand and remember. This is almost always set to automatic for a home network.


Digital Subscriber Line is a form of high-speed internet that uses the phone company’s existing phone lines that come into your home. Usually has several different speeds to choose from, but is an older type of connection and can be less reliable.

The technology is used to create a computer network by sending data through the existing telephone wiring in your home’s walls. An older technology that is not as reliable or fast as other choices.


A hardware device is used to expand the number of ethernet connections available, not a “smart” device such as a switch or router; so it will not make decisions on network traffic, it will only broadcast data on all ports.

IP address:

Similar to the address for a house, it’s used to determine which computer is which. All devices on a network have an address in the form of 4 numbers separated by dots; such as which is an example of a private address used for home networking.

Network Interface Card:

Otherwise referred to as a NIC, this is an expansion card you insert into your computer in order to give it away to connect to a network, could be an Ethernet card with an RJ-45 connection, or could be a wireless card, or an HPNA card the most common type is a PCI card with an Ethernet connection.

Peripheral Component Interconnect is one of the most common types of connections on your motherboard, for adding internal devices. PCI adapters/cards can be used to connect networking devices, additional ports, sound cards, and some older video cards.


Also Known As-PC Card Personal Computer Memory Card International Association is the term for the connection that laptops use to interface/communicate with add-on cards that slide into the slots on the side; such as network adapters, modems, hard drives, or memory. PCMCIA comes in three different sizes: Types I, II, and III.


A Hardware device that acts as the “conductor” of a network, directing all traffic as to where it should be going by using information such as TCP/IP addresses. The router is usually the device that assigns each network device its address and is responsible for your wireless security, based on its configurations.
