Answer:
C. control unit.
Explanation:
A processor is a miniaturized central processing unit a in digital system that interconnects and controls the activities of other components in the device.
The components of a microprocessor are the bus, registers, cache memory, arithmetic and logical unit and the central or control unit.
The bus is the transportation medium for all activities in the processor. The registers like the accumulator and the B register are memory locations used to hold the operand of an operation.The cache memory holds data meant for immediate use by the processor. Arithmetic and logical unit carries out the various arithmetic and logical operation in the processor, while the control unit is responsible for handling or managing all activities in the processor.

Answer:
Bits
Explanation:
The protocol data unit is the representative unit of data in the OSI layer of a network. The OSI system has seven layers.
The physical layer is the first layer of the system and the protocol data unit is represented as bits of data.
Note that the term packet is the PDU for data in the network layer of the OSI network system.
Answer:
a) Speedup gain is 1.428 times.
b) Speedup gain is 1.81 times.
Explanation:
in order to calculate the speedup again of an application that has a 60 percent parallel component using Anklahls Law is speedup which state that:
Where S is the portion of the application that must be performed serially, and N is the number of processing cores.
(a) For N = 2 processing cores, and a 60%, then S = 40% or 0.4
Thus, the speedup is:
Speedup gain is 1.428 times.
(b) For N = 4 processing cores and a 60%, then S = 40% or 0.4
Thus, the speedup is:
Speedup gain is 1.81 times.
