network

A group of two or more computers (or nodes) that are configured to share information and resources such as printers, files, and databases.

router

A r_________ transfers packets of data between two or more networks. On a home network, you need one to transfer data between your network and the Internet, which is considered a separate network. To add WiFi to your home network, you need one that features wireless capabilities.

switch

A s_______ acts like a traffic signal on a network. All routers sold for home use have integrated ones. They receive data packets and send them to their intended nodes on the same network (not between different networks).

transmission media

All network nodes are connected by t____________ m______ that can be wired or wireless. They establish communication channels between nodes. The type of network and the distance between nodes determines the type of cable used: Twisted-pair cable is made up of copper wires that are twisted and surrounded by a plastic jacket. A slightly different type, called unshielded twisted pair (UTP) cable, is used is used for networks. Coaxial cable consists of a single copper wire surrounded by layers of plastic. Fiber-optic cable is made up of plastic or glass fibers that transmit data at extremely fast speeds.

C________ c________ consists of a single copper wire surrounded by layers of plastic.

digital subscriber line

DSL (d_______ s_________ l____) uses twisted-pair cable to connect your computer to the Internet. The bandwidth of the wires is split into three sections. One is used to carry voice data. DSL uses the remaining two lanes to send and receive data.

Data transfer rate, bandwidth

D_____ t_________ r______ (also called b__________) is the maximum speed at which data can be transmitted between two nodes on a network.

The three main UTP cable types used in home networks have different d______ t___________ r______. (100-1000 Mbps for Cat 5E; 1,0000 and higher Mbps for Cat 6, 10 Gbps and higher for Cat 6a)

5E, 6, 6a

The three main types of UTP cable used in wiring Ethernet home networks are: Cat __: It was designed for 100 Mbps - wired Ethernet networks that were popular before gigabit Ethernet networks became the standard. (OLD) Cat _: It's probably the best choice for a home networking cable. It is designed for 1Gbps. (1,000 Mbps) Cat __: This cable is designed for ultra-fast Ethernet networks that run at speeds as fast as 10 Gbps. Installing a 10-gigabit Ethernet network in the home is probably unnecessary because today's home applications don't require this rate of data transfer.

computer network

What is simply two or more computers that are connected using software and hardware so they can communicate?

broadband modem (cable/DSL modem), Ethernet cable

Your router should be connected directly to your b___________ m_______ (cable/DSL). The connection should be an E__________ c________ running from an Ethernet port on your modem to the modem port on your router. Then, all computing devices—such as an HDTV, a tablet, and a laptop—are connected to the router via a wired or wireless connection. Some routers have integrated modems so that you only need one device.
