Question
Please answer the follow questions below with True or False:
T F While a star network forfeits efficiency and close control, a major advantage of this design is that the entire network is independent of the central computer. T F An advantage of a ring network is that if a network device (such as a PC or printer) fails, the devices downstream from the failed device still can communicate with the network. T F TCP/IP consists of many individual protocols that control the handling of files, mail, and addresses, among others. T F Various types of individual and site licenses are available from software vendors. T F In unit testing, the programmer who wrote the program usually creates the test data and reviews the results. T F When the output from a validation program becomes input to a master file update program, testing the two programs independently guarantees that the data passed between them is correct. T F A testing sequence should move to the integration stage as soon as it has performed properly in any unit tests. T F Commercial software packages must undergo unit and integration testing similar to that of in-house developed systems, although system testing usually is not performed. T F Testing should be regarded as a cost-effective means of providing a quality product. Systems analysts prepare overall documentation, such as process descriptions and report layouts, early in the SDLC. T F A systems analyst prepares most of the systems documentation during the systems analysis and systems design phases. T F The skill set required to develop documentation usually is the same as that to develop a system. T F Systems analysts seldom are responsible for preparing documentation to help users learn a system.Explanation / Answer
Ques 57) False
In Star topology, all the components of network are connected to the central device called "hub".
In star topology, all data passes through the central device before reaching the intended destination.
Hub acts as a junction to connect different nodes present in Star Network,
and it manages and controls the whole network.
Ques 58) False
In Ring Topology, all the nodes are connected to each-other in a closed loop.
Each node is connected to two other node on either side, and it communicates with these two adjacent neighbors nodes.
The main disadvantage of ring topology is If one device goes down, the entire network gets affected.
