Calcium is a necessity and makes your bones stronger. It typically comes in milk.
In the case above, the the new subnet mask in prefix format is seen in IPv6 and in IPv4.
<h3>What is
subnet prefix mask?</h3>
A lot or a single computer that is known to be linked to a subnet is said to shares a kind of an identical part of the IP address.
Note that this shared information is said to be called the routing prefix, and in IPV4 (Internet Protocol Version 4), the routing prefix is said to be called a subnet mask.
Hence, The the new subnet mask in prefix format is seen in IPv6 and in IPv4 because that is the format that it always comes in.

In a polling-based network receives, the operating system keeps checking the status register after a fixed time interval to see whether a device needs hardware attention or not. CPU gradually checks the status of receive bit after a defined time interval of a clock and if the value of receive bit is true then data is moved from the RX register to the memory. In interrupt-based networks, whenever a device needs hardware processing then an interrupt is raised to inform the CPU for device attention. The data of the device is transferred to memory from the network card.
Polling is a protocol, not a hardware mechanism where the device gets attention by CPU. An interrupt is a hardware mechanism, not a protocol where the device gets attention by the interrupt handler. In polling, during receiving, parts of received data need to transfer to memory but in case of interrupts, whole data is transferred at once after receiving is done. An interrupt is a heavy operation as compared to pooling because hardware involves in it. For large amounts of data, Polling becomes an inefficient method. In polling, CPU gradually checks devices at regular intervals whereas the Interrupt handler can send interrupt at any time. Each device has its own Command ready bit which indicates whether the device requires servicing or not. In polling, CPU wastes numerous clock cycles by repetitively checking the command-ready little bit of each device. In Interrupt based network, the interrupt request line indicates whether the device requires servicing or not. In interrupt-based network, CPU cycles not wasted but CPU is disturbed only when device send interrupt signals.
Relative performance between programmed I/O and DMA:
For determining the relative performance between programmed I/O and DMA, important factors are:
1. Size of data
2. Frequency of operations
Answer:
The function definition to this question can be given as:
Function definition:
void printAttitude(int x1) //define function printAttitude.
{
//nested else-if statements
if(x1==1)
//if block
cout<<"disagree"<<endl;
//message
else if(x1==2)
//else if block
cout<<"no opinion"<<endl;
//message
else if(x1==3)
//else if block
cout<<"agree"<<endl;
//message
else
cout<<" ";
}
Explanation:
In the above method definition firstly, we define a method that is "printAttitude". In this method, we pass an integer variable that is "x1". This function does not return any value because its return type is void. In this method, we use nested else-if statements. The description of these conditions can be given as:
- In the if block we check the variable x1 value is equal to 1 If this condition is true. It will print "disagree" otherwise it will go to else-if block.
- In the else-if block, we check the variable x1 value is equal to 2 if the condition is true. It will print "no opinion". otherwise, we will go to another else-if block.
- In this block, we check the variable x1 value is equal to 3 if this condition is true. It will print "agree".otherwise it will go to else block.
- In the else block it will print nothing.
