Answer:
A. 31 bits
B. 13 bits, 18 bits
C. 256k
Explanation:
A.
We have total size of physical memory as 2gb
This means that 2¹ x 2³⁰
Using the law of indices,
= 2³¹
So physical address is equal to 31 bits
B.
We get page size = 8kb = 2³
1 kb = 2¹⁰
2³ * 2¹⁰ = 2¹³
So page replacement = 13 bits
Page frame number
= physical address - replacement bits
= 31 - 13
= 18 bits
C.
The number of frames is given as
2¹⁸ = 2⁸ x 2¹⁰ = 256K
So number of frames = 256K
D
Logical add space is 256K
Page size= physical pages = 8kb
Logical address layout= 28biys
Page number = 15 bits
Displacement = 12 bits
256k/8k = 32 pages in address space process
Answer:
Wireless technology.
Explanation:
In earlier years, the broadcasting of information or any video or audio type was done "over-the-air". This means that sharing or the distribution of any content was done "wireless", through the use of transmitters that are wireless or requires no physical connecting wires.
Wireless technological form of broadcasting became the original form of distributing media, be it entertainment, news or information, etc. This 'over-the-air' broadcasting was then replaced by the cabled-wires transmission later on.
