Answer:
Option (b) is the correct and suitable answer for the above question.
Explanation:
The printer is a hardware which is used to convert the soft copy of an information to a printed copy (Hard copy) of information.
To use printer hardware a computer system needs a printer driver which is used to do the conversion from soft copy to a hard copy. Hardware printer uses only for the purpose to print the copy.
The option b says that the printer driver is used to convert the document into the form of that document which the printer can understand easily. It means conversion from soft copy to hard copy. Hence it is the right option.
The reason behind the other option which is not valid because--
Option a says that the printer driver is a code but it is a software.
Option c says that the printer driver is an interface but it is a software.
Option d says that the printer driver is a cache but it is a software.
Answer:
(c) system.exist(1);
Explanation:
system.exist(1); is used for the termination of the program here both option c and d should be correct but in option d there is exit(0) and zero indicates return means program will return but besides zero if there is any non zero number then program will not return and in option c there is a non zero number which means program will not return so option c system.exist(1); will be the correct option for the termination of program
Answer:
To make sure that data sent from a device is just received by appropriate device we use "<u>Switch</u>"
Explanation:
Switch is the networking device. It is used to connect all the Local area networks in a computer network. The switch store the addresses of all computers over the network. Whenever data packet arrives to the switch, it just read the address of destination computer and just send it to appropriate device instead of all devices.
Hub is also used for this purpose, but it has no ability to read the address and send the packet to all devices over the network.
<em>So, we use Switch to send data to appropriate device.</em>
