Question
Q 1. (a) Data are transmitted over a particular Ethernet network in blocks of 1500 bytes, How
many blocks are required to transmit the following amounts of data over this Ethernet network?
(Note that a kilobyte is 1000 bytes, and a megabyte is 1,000,000 bytes.)
(i) 150 kilobytes of data
(iii) 45.3 megabytes of data
(b) Write down an algorithm that calculates the logarithmic (i.e. log:N) value of an integer N.
(c) Briefly justify why do we study algorithms? What are the main factors that affect the efficiency
of an algorithm?
