Explanation:
Answer:
While statements determine whether a statement is true or false. If what’s stated is true, then the program runs the statement and returns to the first step. If what’s stated is false, the program exits the while and goes to the next statement. An added step to while statements is turning them into continuous loops. If you don’t change the value so that the condition is never false, the while statement becomes an infinite loop.
If statements are the simplest form of conditional statements, statements that allow us to check conditions and change behavior/output accordingly. The part of the statement following the if is called the condition. If the condition is true, the instruction in the statement runs. If the condition is not true, it does not. The if statements are also compound statements. They have a header (if x) followed by an indented statement (an instruction to be followed is x is true). There is no limit to the number of these indented statements, but there must be at least one.
Answer: The difference present between the packet switching and circuit switching are as follows:-
- Packet switching i the switching in which the data packet travels through the connectionless path whereas connection oriented routes are present for circuit switching
- Network layer uses the feature of packet switching while physical layer uses circuit switching technique
- Data transferring is mostly preferred through packet switching and voice communication takes place through the circuit switching.
- Packet switching is considered flexible as no already established connection is present for switching but the connection in circuit switching are already defined which makes it less flexible.
Among the packet switching and circuit switching , packet switching is preferred for the communication through the data packets because they have flexibility and affordability.It can establish numerous connection for switching and this make it efficient.
