Q:

What resources are used when a thread is created? How do they differ from those when a process is created?

Answer

When a thread is created the threads does not require any new resources to execute the thread shares the resources like memory of the process to which they belong to. The benefit of code sharing is that it allows an application to have several different threads of activity all within the same address space. Whereas if a new process creation is very heavyweight because it always requires new address space to be created and even if they share the memory then the inter process communication is expensive when compared to the communication between the threads.

Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.

My coat's pretty warm, even though it cost £9.99 and came from the flea market. It had a label in it, CHRISTIN BIOR, but I cut it out as soon as I got home. You can't work where I work and have CHRISTIN BIOR in your coat. You could have a genuine vintage Christian Dior label. Or something Japanese. Or maybe no label because you make your clothes yourself out of retro fabrics that you source at Alfies Antiques. But not CHRISTIN BIOR.

As I get near Catford Bridge, I start to feel a knot of tension. I really don't want to be late today. My boss has started throwing all sorts of hissy fits about people "swanning in at all times," so I left an extra twenty minutes early, in case it was a bad day. I can already see: It's a god-awful day. They've been having a lot of problems on our line recently and keep cancelling trains with no warning. Trouble is, in London rush hour, you can't just cancel trains. What are all the people who were planning to get on that train supposed to do? Evaporate?

A) Those with the Christian Dior label. B) Any Japanese brand.
C) Clothes stitched by herself. D) Those with the CHRISTIN BIOR label.
