Question

For a process that has a parallel fraction (alpha) of 99.2%:

7a) Calculate the break-even point.

7b) Calculate the theoretical speedup at the break-even number of processors.

7d) Calculate the theoretical speedup if 2000 processors can be used (are available in the architecture).

7e) Explain what is meant-by CSMA-CD?

7f) Why is the Ethernet (original) frame size set to 576 bits?

7g) Explain the difference between a connection-oriented and connectionless packet transport strategy.   With TCP/IP, what protocol is connectionless and what protocol is connection-oriented?

7h) Explain the theoretical basis behind caching effectiveness.

7i) List and explain the three problem areas that limit the realizable speedup from the use of pipelines.

7j) Explain why modern processors use a RISC design as opposed to the other CISC design.

Explanation / Answer

7e) Explain what is meant-by CSMA-CD

Answer:

Carrier Sense Multiple Access with Collision Detection is a type of protocol for networks that helps to triage transmissions and control network traffic. CSMA/CD and similar protocols have been used in Ethernet connections to manage traffic between different hardware devices.

Carrier Sense Multiple Access with Collision Detection is a media access control (MAC) method. With this protocol, the points of origin essentially "listen" for traffic before transmitting. Devices wait for a clear space before signaling. Moreover, with this protocol, there is the addition of more defined tools for stopping a transmission as soon as a collision is detected. This specific type of CSMA further qualifies the structures for network traffic, which has improved Ethernet cabling networks in LANs and WANs and other types of network setups
