Ch2 Qz2 Flashcards
With a client-based network, one fundamental problem is that:
the clients each must store all the data
the server does not have any data storage capability
the host or server must perform presentation logic, application logic, and data access logic at the same time
all data on the server must travel to the client for processing
the clients must perform the data storage logic
all data on the server must travel to the client for processing
The two functions of middleware are to: 1) provide a standard way of communicating that can translate between software from different vendors, and 2) manage the message transfer between clients and servers so that clients do not need to ‘know’ which server contains the application’s data.
True
False
True
One major drawback to a client-server network lies in the fact that client-server networks enable software and hardware from different vendors to be used together.
True
False
False
To use the Web, each client computer requires a data link layer software package called a Web browser.
True
False
False
With respect to costs for a client-server network, which of the following is true?
Personal computers used as clients in a client-server network cost about the same as mainframes for the same amount of computing power.
More network capacity, which costs more money, is required for client-server networks than for client-based networks.
Experts believe that client server architectures can be complex, but that developing application software for host based architectures is usually cheaper.
Updating the network with new version of software tends to be less expensive in a client-server network since the software is centralized in one client.
None of these.
Experts believe that client server architectures can be complex, but that developing application software for host based architectures is usually cheaper.
A response status code of 404 means:
the requested page was not found.
the server is currently unavailable.
the sever is currently busy.
your browser is incompatible with the Web server software.
your browser needs to be updated to the latest version.
the requested page was not found.
