Physical layer:

  • Physical layer is the connection between the sender and receiver that includes hardware devices and physical media.
  • Hardware devices such as computers, mouse, modems, and so on.
  • Physical media such as cables and satellites.
  • It transmits data bits 0’s and 1’s over a connection.

Explanation of Solution

Difference between point-to-point circuit and multipoint circuit:

Point-to-point circuit

Multipoint circuit

Point-to-point configuration means that it goes from one computer to another computer.

Multipoint configuration means that many computers are connected on the same circuit.

This circuit is also called dedicated circuits.This circuit is also called shared circuit.

It is used when the computers generate enough data to fill the capacity of the communication circuit.

It is used to share the circuit with others.

This circuit is expensive.

This circuit is cheaper.

For a hierarchical carry look-ahead adder, GO can be written like below. Find the gate delay needed to obtain GO without fan-in and with a fan-in of 3 inputs. GO=g7+p7g6+p7p6g5+p7p6p5g4+p7p6p5p4g3+p7p6p5p4p3g2+p7p6p5p4p3p2g1+p7p6p 5p4p3p2p1g0 Select one: a. O b. GOO B B GO without fan-in limitation will require 3 gate delays GO with fan-in limitation of 3 will require 5 gate delays GO without fan-in limitation will require 4 gate delays • GO with fan-in of 3 will require 3 gate delays C. • GO without fan-in limitation will require 5 gate delays GO with fan-in limitation of 3 will require 3 gate delays O d. GO without fan-in limitation will require 2 gate delays GO with fan-in limitation of 3 will require 4 gate delays
