Suppose you have a 16-bit machine with a page size of 16B. Assume that any unsigned 16-bit integer can be a memory address. Also

, assume that the machine can support up to only 32KB of physical memory. (1K = 210)
Required:
For paging-based memory allocation, how many page table entries do you need to map the virtual address space of a process, with pure paging alone?

Answer:

2^11

Explanation:

Physical Memory Size = 32 KB = 32 x 2^10 B

Virtual Address space = 216 B

Page size is always equal to frame size.

Page size = 16 B. Therefore, Frame size = 16 B

If there is a restriction, the number of bits is calculated like this:  

number of page entries = 2^[log2(physical memory size) - log2(n bit machine)]

where

physical memory size = 32KB  which is the restriction

n bit machine = frame size = 16

Hence, we have page entries = 2^[log2(32*2^10) - log2(16)] = 2ˆ[15 - 4 ] = 2ˆ11

Elden [556K]

Answer:

Tech B is correct.

Explanation:

First, It is international best practice never to exceed the lifting capacity of any hoist. To do so would expose those involved to risks that may prove to be fatal.

Second, research has shown that gasoline vapors, as well as vapor from almost all other flammable or ignitable liquids or substances, are heavier than air.

More specifically, Gasoline produces flammable vapors that are heavier than air by 3 to 4 times. This means they can travel for great distances along the ground. Worst still, inspection pits are must be kept free from gas vapors because they tend to accumulate in low or enclosed spaces.

Both technicians should and must observe all occupational, health, and safety rules and guidelines stipulated and required for their industry/practice.

Write a program that reads a string from the user containing a date in the form mm/dd/ yyyy. It should print the date in the for
Oxana [17]

Answer:

months_info = ['January', 'February','March','April', 'May','June', 'July','August', 'September', 'October', 'November', 'December']

date = input('Enter a date using the mm/dd/yyyy format ')

m, d, y = date.split('/')

m = int(m) - 1

name_of_month = months_info[m]

print('{} {}, {}'.format(name_of_month, d, y))

Explanation:

  • Create a list of all months and store them in the months_info variable.
  • Get the date as an input from user and then split the date.
  • Finally display the date by following the specific layout using the built-in format method.
