True
As the size of a business changes, it is easier to alter the capability of a large-scale central server than it is to adjust the number of clients and the processing functions they perform.
False
Client/server architecture does involve performance issues that relate to the separation of server-based data and networked clients that must access the data.
True
A server is a computer that supplies data, processing services, or other support to one or more computers, called clients.
True
The cloud computing concept envisions a cloud of remote computers that provide a total online software and data environment that is hosted by third parties.
True
Although many factors influence the decision to build or buy, the most important consideration is the total cost of ownership (TCO). An accurate forecast of TCO is critical, because nearly 80% of total costs occur after the purchase of the hardware and software, according to Gartner, Inc. An IT department can develop its own TCO estimates or use TCO calculation tools offered by vendors.
