11.

(i) There are two types of accessing methods to access (read and write) the memory.
(ii) They are sequential access and random access. In sequential access, the memory is accessed an orderly manner from starting to end.
(iii) But, in random access, any byte of memory can be accessed directly without navigating through previous bytes.

12.

(i) CISC stands for Complex Instruction Set Computers.
(ii) They support hundreds of instructions. Computers supporting CISC can accomplish a wide variety of tasks, making them ideal for personal computers.
(iii) Examples of CISC processors are Intel 386 & 480 Pentium, Pentium II and Ill, and Motorola 68000

13.

(i) RISC stands for Reduced Instruction Set Computers. They have a small set of highly optimized instructions.
(ii) Complex instructions are also implemented using simpler instructions, thus reducing the size of the instruction set.
(iii) Examples of RISC processors are Intel P6, Pentium IV, AMD K6 and K7.

14.

(i) Serial Port
(ii) Parallen Port
(iii) USB 3.0
(iv) VGA connector
(v) Audio plugs
(vi) PS/2 Port
(vii) SCSI Port
(viii) High Definition Multimedia Interface(HDMI).

15.

PROM	EPROM

Generic 5

2 x 5 = 10

23.

(a) Bus:
A bus is a collection of wires used for communication between the internal components of a computer.
(b) Data bus:
(i) Data busis a collection of wires to carry data in bits.
(ii) A data bus is used to transfer data between the memory and the CPU.
(iii) The data bus is bidirectional.
(c) Address bus:
(i) Address bus is a collection of wires to carry data in bits.
(ii) The address bus is used to point a memory location.
(iii) The address bus is unidirectional.

(i) Control bus is a control line/collection of wires to control the operation/functions.
(ii) The control bus controls both read and write operations.

24.

(i) The size of the instruction set is another important consideration while categorizing microprocessors.
(ii) Initially, microprocessors had very small instruction sets because complex hardware was expensive as well as difficult to build.
(iii) As technology had developed to overcome these issues, more and more complex instructions were added to increase the functionality of the microprocessor,
(iv) Let us learn more about the two types of microprocessors which are based on their instruction sets.
(v) RISC stands for Reduced Instruction Set Computers. They have a small set of highly optimized instructions.
(vi) Complex instructions are also implemented using simpler instructions, thus reducing the size of the instruction set.
(vii) Examples of RISC processors are Intel P6, Pentium IV, AMD K6 and K7.
(viii) CISC stands for Complex Instruction Set Computers. They support hundreds of instructions. Computers supporting CISC can accomplish a wide variety of tasks, making them ideal for personal computers.
(ix) Examples of CISC processors are Intel 386 & 486, Pentium, Pentium II and III, and Motorola 68000.
