Q2. What is a bus? Explain its
structure. 4+6 = 10
Ans:
What is a bus: A bus consists of 1 or more
wires. There's usually a bus that connects the CPU to memory and to disk
and I/O devices. Real computers usually have several busses, even though
the simple computer
Q3. Explain the how instruction
are represented in CPU with necessary diagram and example. 6+4 = 10
Ans:
Instruction Representation: Each instruction is
represented by a sequence of bits. The instruction is divided into
fields, corresponding to the constituent elements of the instruction.
This layout of the instruction is called Instruction Format. With most
instruction sets, more than one format is
Q4. Explain memory interleaving
with the help of a diagram. 6+4 = 10
Ans:
Memory interleaving: Another technique
called memory interleaving divides the system into a
number of modules and
arranges them so that successive words in the address space are placed in
different modules. If memory access requests are made for consecutive
addresses, then the access will be made for different modules. Since parallel
access to these modules is possible, the average rate of fetching words
Q5.
What is magnetic disk? Describe data organization and formatting of magnetic
disk. 3+7 = 10
Ans:
Magnetic Disk: A disk is a circular
platter constructed of metal or of plastic coated with a magnetic
material. Data are recorded on and later retrieved from the disk via a
conducting coil named the head. During a read or write operation, the
head is stationary while the platter rotates beneath it. Writing is
achieved
Q6. What is an interrupt? Explain
how CPU responses to an interrrupt. 5+5 = 10
Ans:
Interrupt: An interrupt is an
exception condition in a computer system caused by an event external to
the CPU. Interrupts are commonly used in I/O operations by a device
interface (or controller) to notify the CPU that it has completed an I/O
operation. An interrupt is indicated by a signal sent by the device
interface to the CPU via an interrupt request line (on an external bus).
This signal notifies the CPU
