- Correct Answer
- JAD (Joint Application Development) is a methodology that involves the client or end user in the design and development of an application, through a succession of collaborative workshops called JAD sessions The JAD approach, in comparison with the more traditional practice, is thought to lead to faster development times and greater client satisfaction, because the client is involved throughout the development process In comparison, in the traditional approach to systems development, the developer investigates the system requirements and develops an application, with client input consisting of a series of interviews

Correct Answer: network layer
Correct Answer: A network that has only one entry and exit point.
Explanation:
A stub network has only one default path to non-local hosts and no outside network knowledge. Non-local stub network traffic uses a single logical path when traveling in and out of the network.
Stub networks are essentially local area networks (LAN) that either do not connect to the outside and relay data packets internally or are dead-end LANs that know of only one network exit. Stub networks may have multiple connections but use one path to single points of destination.
Hence, a stub network is a network that has only one entry and exit point.
Correct Answer: - Divide the data into sections - Add the sections together using 1's complement arithmetic - Take the complement of the final sum, this is the check sum
Correct Answer: Research
Correct Answer: When the computers on the network simply listen and receive the signal, they are referred to as passive because they don?t amplify the signal in any way Example forpassive topology - linear bus
Correct Answer: Traceability matrix is a cross matrix for recording the requirements through each stage of the requirements gathering process This matrix should also take into account any changes in the scope during the life of the project At the end of the project this matrix should show each function built into a system, its source and the reason that any stated requirements may not have been delivered
