Handling integrity and security is actually one of the strengths of file servers. File servers are designed to centralize data control and provide strong security measures to protect against unauthorized access or changes to files. The limitations typically include excessive data movement, the need for powerful client workstations, and decentralized data control which can lead to inconsistencies in data.

Question 9

The ________ functions of an IS manage just the interface between system users and the software,including the display and printing of forms and reports and possibly validating system inputs.
A)Data presentation
B)Data analysis
C)Middleware
D)Data management

Accepted Answer

The data presentation functions of an IS focus on the user interface and how data is presented and displayed to system users. This includes forms, reports, and validating inputs, but not the actual storage and management of data (which falls under data management) or data analysis (which involves using the data to derive insights and make decisions). Middleware is a type of software that connects different applications and systems together.

Question 10

Which of the following is NOT a feature of a file server in a file server model?
A)File storage
B)Significant LAN traffic
