Answer:
The answer is below
Explanation:
a)
If the blocks of a file are not put together, that is for nonadjacent block of files to each other, the time (t) taken to read a 100 block file is:
t = (average seek + rotational latency + transfer time) * 100 block
Average seek = 5 msec, rotational latency = 10 msec and transfer time = 20 microsec = 0.02 msec
t = (5 + 10 + 0.02) * 100 = 1502 msec
b)
If the blocks of a file are put together, that is for adjacent block of files to each other, the time (t) taken to read a 100 block file is:
t = (seek time * mean interblock distance + rotational latency + transfer time) * 100 block
seek time = 100 microsec = 0.1 msec, rotational latency = 10 msec and transfer time = 20 microsec = 0.02 msec, mean interblock distance = 2 cylinders
t = (0.1*2 + 10 + 0.02) * 100 = 1022 msec

Hey there!
The main memory of a computer that includes RAM, ROM, and cached information that is accessible through the CPU is called primary storage. These memory/storage types deal directly with how the computer functions and runs. The other type of storage is called secondary storage and refers to storage that isn't directly connected to the CPU, such as the hard drive.
Hope this helped you out! :-)
Answer:
True
Explanation:
Using personal computers for internet access has various advantages because of the physical attributes of these computers. One of the major reason that it is good for internet access is its large screen. The large screen allows things to be easily viewed and read. Also, personal computers have a keyboard that helps for easy data entry, as opposed to pads, and other types of devices that may have just touch-pad and data entry may be difficult.
