Compute the required memory cycle time of given "time slot interchange" switch?

In a time slot interchange (TSI) switch, 8 input lines are scanned in sequence to build up an input frame with 8 slots. The incoming lines each produce 16KBps (B=Byte). Each slot in the TSI switch holds 8 bits. What is the required memory cycle time of this switch?

What is the throughput in frames/sec for a slotted Aloha channel?

A group of stations share a 16 kbps slotted Aloha channel. Each station outputs a 80 Bytes frame and buffers any outgoing frames until they can be sent. Collectively (recall that this means original frames plus resending of frames that suffered a collision previously) the stations attempt to send 30 frames/sec. What is the throu ...continues

Find the span of an element in the given non-decreasing sorted sequence.

Give the pseudo code for finding the span of an element in a non-decreasing sorted sequence of given length. Sequence is indexed from 1 onwards. For example, in the sequence {0,2,3,3,4,5,5,5,5,6,8,10,11,11,12}, span of element 5 is [6-9], and for element 2 it is [2,2].
