Answer:John Mauchly and Presper Eckert
Explanation:
Answer:
They result in a clear and concise statement of the problem
They ensure that all stakeholder needs are considered.
They result in a document that is easy to understand
Explanation:
Problem statement are very vital in research they are key notes that tells what the research is all about and solution it will provide. They are key notes to understand a research and the knowledge gap the research is filling.
Problem statement is a guide through which solution are measured, it gives a clear direction of what the research is all about.
Problem statement are usually easy to understand, they are written in ways that everyone who picks the paper up can understand why the research was conducted.
All this are why a problem statement is important.
Answer:
C
Explanation:
When an Ethernet NIC has been configured by the OS to use half-duplex, the transmit pair of the cable uses SIMPLEX transmissions, the receive pair in the SIMPLEX transmissions, and the twisted pair cable uses HALF-DUPLEX transmissions.

Answer:
Advantages of both circuit switched networks and TDM are given below:
Explanation:
Advantages of circuit switched network over packet switched network:
- Circuit switched network has the advantage of being physically connected and having a dedicated channel for communication between the sender and the receiver which also makes it more reliable. Packet switched networks do not have a dedicated channel hence, they are not that reliable.
- Circuit switched networks are used for voice calls because there is no timing jitter or delay in these types of networks while packet switched networks do not offer this advantage.
Advantages of TDM over FDM in a circuit switched network:
- TDM is time division multiplexing i.e. multiple information is sent in different time intervals but on the same frequency. While FDM sends information using different frequencies. So, the advantage of using TDM is that the information will be sent from the sender to the receiver using only a single frequency.
- Using TDM, bandwidth is saved because it only sends information on a single frequency unlike FDM.
- In TDM, there is low chance of interference between signals since they are sent in different time intervals from the sender to the receiver. While FDM has a higher chance of interference.
