System A needs to send a 10 Mb file to system B using Selective-Reject ARQ network transport protocol. Both system A and B have buffers large enough to handle the sliding window protocol. Each packet will contain L = 1024 bits of data. The distance between A and B is d = 2 km, the propagation velocity V = 2 x 10^8 m/sec, and the transmit data rate is N = 500 Mbps, and the probability of an error P is 0.001. What is the minimum window size required for maximum network utilization? a. 2048 b. 10 c. 11 d. 4

Create a data model in the form of an Entity-Relationship Diagram to express the following data requirements of a certain information system. A medical clinic wants to record data about its doctors and patients. They also need to know about the appointments scheduled. Following each appointment a doctor will update the patient's medical record with the diagnosis and any prescriptions. Other examinations by specialists may also be requested. Make logical assumptions about the maximum and minimum occurrences of entities in order that you may complete all the relationships.
