Answer:
Control bus
Explanation:
A control bus is a PC bus that is utilized by the CPU to speak with gadgets that are contained inside the PC. This happens through physical associations, for example, links or printed circuits.
The CPU transmits an assortment of control sign to parts and gadgets to transmit control sign to the CPU utilizing the control bus. One of the principle targets of a transport is to limit the lines that are required for communication
An individual bus licenses communication between gadgets utilizing one information channel. The control transport is bidirectional and helps the CPU in synchronizing control sign to inside gadgets and outer segments. It is included interfere with lines, byte empower lines, read/compose sign and status lines.
Answer: True
Explanation:
Virtual memory is the secondary storage memory and this type of memory are addressed as main part of the memory.
When the virtual memory copying in the physical memory then, at that time the operating system divide the memory into the file page with the address and definite size number. Then, the each page are store in a disk.
When this page are required then, the operating system copy from disk to main memory and then, the virtual address are converted into the real address.

Answer:
b) Bounded Waiting
Explanation:
int currentThread = 1;
bool thread1Access = true;
bool thread2Access = true;
thread1 { thread2 {
While (true) {
While (true)
{
while(thread2Access == true)
{
while(thread1Access == true)
{
If (currentThread == 2) {
If (currentThread == 1)
{
thread1Access = false; thread2Access = false;
While (currentThread == 2);
While (currentThread == 1);
thread1Access = true; thread2Access = true;
} }
/* start of critical section */ /* start of critical section */
currentThread = 2 currentThread = 1
… ...
/* end of critical section */ /* end of critical section */
thread1Access = false; thread2Access = false;
… ...
} }
} }
} }
It can be seen that in all the instances, both threads are programmed to share same resource at the same time, and hence this is the bounded waiting. For Mutual exclusion, two threads cannot share one resource at one time. They must share simultaneously. Also there should be no deadlock. For Progress each thread should have exclusive access to all the resources. Thus its definitely the not the Progress. And hence its Bounded waiting.
