UGC NET CSE | December 2014 | Part 2 | Question: 37

Question

A specific editor has $200 K$ of program text, $15 K$ of initial stack, $50 K$ of initialized data, and $70 K$ of bootstrap code. If five editors are started simultaneously, how much physical memory is needed if shared text is used?

• A. $1135 K$
• B. $335 K$
• C. $1065 K$
• D. $320 K$ 

Answer 1

initial stack, initialized data, and bootstrap code can be shared among the editors.

Given that text is also shared,

then total memory =200+15+50+70 =335K

Comments

how can u elaborate more eg  chrome brower same program text will be shared but other would be different @sh!va

Answer 2

Answer is B,

Because text is shared so no need to multiply 200 with 5.

and other need each for running

so answer is 200+15+50+70=335

Answer 3

Ans (B) 335K <= (200K + 15K + 50K + 70K)

Reason is provided in the snapshot below. 

Answer 4

5 editor works simultaneously

Each editor must have separate code in each.

But they could share initial stack, initialized data and bootstrap code

So, total memory required 200*5+15+50+70=1135 K

But answer is given as 335K
