a. The _bus_ physical topology consists of a single cable that connects all nodes on a network without intervening connectivity devices.

b. A _serial__ backbone is the simplest kind of backbone.

c. Fast Ethernet operates at _100-Mbps_.

d. _A Switch_ is a component of a network’s logical topology that determines how connections are created between nodes.

e. One thing all Ethernet networks have in common is their access method, known as _CSMA/CD__.

A way to set up the small offices network would be with a star-wired ring topology network. A star topology is planned with each node (file server, workstations, and peripherals) linked right to a dominant system hub, switch, or concentrator (See fig. 1).

Information on a star network clears through the hub, switch, or concentrator before ongoing to its end point. The hub, switch, or concentrator manages and controls all roles of the system. It also performs as a repeater for the data stream. This arrangement is shared with twisted pair cable; however, it can also be used with coaxial cable or fiber optic cable.

• Easy to install and wire.

• No disruptions to the network when connecting or removing devices.

• Easy to detect faults and to remove parts.

The small lab as recently expanded its computer network. With the star-wired ring topology it is easy to expand or change any device in the network. A star-wired ring will have no disruptions to the network when connecting or removing devices.

Since the store uses seven computers and a printer, the star-wired ring allows the hub, switch, or concentrator to manage and control all roles of the system (Winkelman, 2013). The printer will also run through the switch, router, or hub.

The specialized computers can be attached and allow every other computer access to their information also. This will allow the workers to remain at their own workstations...
