Which of the following statements about client/server computing is true?
It exploded the available communications capacity.
It provided communication rules and regulations.
It connects multiple powerful personal computers together in one network with one or more servers dedicated to common functions that they all need.
It does not provide sufficient computing capacity to support graphics or color.
Which of the following is not an advantage of client/server computing over centralized mainframe computing?
It is easy to expand capacity by adding servers and clients.
Each client added to the network increases the network's overall capacity and transmission speeds.
Client/server networks are less vulnerable, in part because the processing load is balanced over many powerful smaller computers rather than concentrated in a single huge computer.
There is less risk that a system will completely malfunction because backup or mirror servers can pick up the slack if one server goes down.
