distances?
Answer:
radio and cellphone towers
Q: Which of the following type of transmission is paired correctly with the given media?
Answer:
fiber optic cable – light impulses
Q: Why would it be desirable to use a switch as opposed to a hub in a network?
Because a switch is a more powerful device, it cannot be used over longer distances compared to
a hub.
Because switches only transfer information to specific computers within a network and not all of
the computers, the bandwidth used with a switch is less than that of a hub.

Q: Which of the following are characteristics of a packet-switched network?
A. The path exists during the entire transmission, allowing communication in either direction to
occur simultaneously.
B. The choice of pathway is based on network availability and amount of message traffic.
C. The route is established one branch at a time.
D. A and B
E. B and C
Answer:
B. The choice of pathway is based on network availability and amount of message traffic.
C. The route is established one branch at a time.
Q: How do a router and switch differ when handling a message?
Both a router and switch use the messages detination address to select the line to route the
incoming message to.
There is no difference in how a router and a switch handle messages.
The switch will purposefully drop messages if message traffic exceed its capacity.
The router will purposefully drop messages if message traffic exceeds its capacity.
Answer:
The router will purposefully drop messages if message traffic exceeds its capacity.
Q: In a client-server network, what is the role of the server?
The role of the service is the same as the role of the clinet because all of the computers on this
type of network are equal.
The role of the service is to maintain connections to remote services.
The role of the server is to take requests from the client and send back the requested information.
The role of the service is to send out requests for info.
Answer:
The role of the server is to take requests from the client and send back the requested information.
Q: How do virtual machines support a business computing system?
A virtual machine is made available by software and permits a computer to run multiple OSs. In
a business ecosystem ths allows for improved collaboration that is not restricted by platform
software.
A virtual machine is a server that users can log into and use different OSs and applications
associated with the different OSs.
A virtual machine is a separate computer that provides users access to an OS different from their
primary computer. Being able to have access to a computer with a different OS facilitates
collaboration in the business ecosystem.
Answer:
A virtual machine is made available by software and permits a computer to run multiple OSs. In
a business ecosystem ths allows for improved collaboration that is not restricted by platform
software.
