1.          Network.

2.          The statement is not correct. Hardware, software, control, or data can be distributed.

3.          Requirements.

4.          The hardware in a distributed system can be configured as host to minicomputers or minicomputers to LAN.

5.          The main characteristic of all distributed systems is that some processing power is located at many different sites.

6.          A distributed system is made up of hardware, operating system software, application software, and data.

7.          Distributed systems should be modular because installation and maintenance of hardware is simpler, and failures are minimized.

8.          The PC loads software from the network, no waiting for a response occurs, no transmission time occurs.

9.          In a decentralized system, each department has its own computer with no links to any other computer. In a distributed system, many computers at various sites are linked by networks.

10.      Problems inherent in decentralized systems were solved by centralization.

11.      The main threat in a centralized computer system is failure of the host computer.

12.      Geographically distant computers result in no centralized control over policies and procedures, and are expensive for programmers to work with users.

13.      A distributed processor at a remote site can perform data entry, editing, and processing of data.

14.      Managers at different sites must coordinate control efforts to manage a distributed system effectively.

15.      A hierarchical distributed system also is called a vertical system. Data moves up and down the hierarchy.

16.      A typical manufacturing distributed system has three levels of computer systems and terminals.

17.      Computer systems that are equal (peer computers) make up a horizontal distributed system.

18.      Location, architecture, operating systems, contention, security, and file directory affect a distributed file system.

19.      Databases were developed to reduce redundant data.

20.      Network name and address are critical for identification in a distributed network.
