Answer:
Switches break up collision domains and routers break up broadcast domains.
Explanation:
- Collision domain depicts the part within a network where a collision can happen.
- Collision occurs when two hosts transmit data packet at the same time within a network. Theses packets collide and the hosts have to resend the data after some time.
- Too many collisions can result in slow traffic speed and can effect network performance.
- So switches break up collision domains between the devices on a network and each port in a switch depicts a collision domain. This reduces the chance of packet collisions between the devices or hosts.
- When data is to be sent to a host, the switch keeps that data frame and waits for availability of the destination host before sending the data frame.
- Moreover full duplex switch mode there is not chance of collision as the transmitting path on one host is the receiving path on other host.
- Broadcast domain contains all the hosts that can reach each other at the Data Link layer via broadcast.
- Routers break up broadcast domains as routers contain separate broadcast domains for each interface.
- Routers do not forward broadcasts from one broadcast domain to other and drop the packet when they detect a broadcast address.
Answer:
Measures including device data encryption, anti-malware software, and communications encryption.
Answer:
x_inp = [ '1', '2', '3']
int_val = [ int(a) for a in x_inp ]
print("integer: int_val")
y_inp = [ '1.0', '2.0', '3.0']
flo_val = [ float(a) for a in y_inp ]
print("float: flo_val")
Explanation:
All the items in the arrays x_inp and y_inp are coverted to integer and float data types respectively with the for loop statement, which individually assigns the resolved integer and float values to the memory locations int_val and flo_val respectively.
The output becomes,
integer:
1
2
3
float:
1.0
2.0
3.0

Explanation:
The difference between entry condition loop is and exit - condition loop is that the entry condition loops first checks the condition to enter the loop body if the condition true then the loop body is executed otherwise loop body is not executed while the exit-condition loops first executes the loop body and then the condition for the loop is checked.
There are three loops in C that are as following:-
- For
- While
- Do While
Among these three loops While and For loops are entry condition loops and Do While loop is exit condition loop.
For example:-
for(int i=0;i<10;i++)
{
printf("%s","John Doe\n");
}
If the initial value of i should have been 10 then loop body didn't had executed.
int i=0;
while(i<4)
{
printf("%s","John Doe\n");
}
If you try to run this while loop nothing will print on the screen because the condition is false.So the compiler will not enter the loop body and will skip over it.
int i=5;
do{
printf("%s","John Doe\n");
}while(i<4);
Even if the condition is false.You will see that the John doe have been printed one time on the screen because first the body is executed then the condition is checked.
