Task 2. Read. Write and Translate Read and Reply Directions: Students are required to read aloud the whole text after the teacher. Then give short answers to the following questions a) How can data be transferred from one register to another? The output conductors of one register are switched onto a channel of parallel wires referred to as a bus. The input conductors of another register, which is also connected to the bus b)What' s the result of a bus contention? Not only will a bus contention result in the loss of information but it also may damage the electronic circuitry. c)What s the function of the buffer circuits? Special buffer circuits may be added to boost the bus signals sufficiently for transmission over several additional feet of conductor length, or for distribution to many other chips 2021/2/20 P7
