1. How many bits would you need to address a 2M × 32 memory if:

Dominik [7]

Answer:

a) 23 b) 21
a) 43 b) 42
a) 0 b) 0

Explanation:

1) How many bits is needed to address a 2M * 32 memory

2M = 2^1*2^20, while item =32 bit long word

hence ; L = 2^21 ; w = 32

a) when the memory is byte addressable

w = 8; L = ( 2M * 32 ) / 8 = 2M * 4

hence number of bits = log2(2M * 4)= log2 ( 2 * 2^20 * 2^2 ) = 23 bits

b) when the memory is word addressable

W = 32 ; L = ( 2M * 32 )/ 32 = 2M

hence the number of bits = log2 ( 2M ) = Log2 (2 * 2^20 ) = 21 bits

2) How many bits are required to address a 4M × 16 main memory

4M = 4^1*4^20 while item = 16 bit long word

hence L ( length ) = 4^21 ; w = 16

a) when the memory is byte addressable

w = 8 ; L = ( 4M * 16 ) / 8 = 4M * 2

hence number of bits = log 2 ( 4M * 2 ) = log 2 ( 4^1*4^20*2^1 ) ≈ 43 bits

b) when the memory is word addressable

w = 16 ; L = ( 4M * 16 ) / 16 = 4M

hence number of bits = log 2 ( 4M ) = log2 ( 4^1*4^20 ) ≈ 42 bits

3) How many bits are required to address a 1M * 8 main memory

1M = 1^1 * 1^20 , item = 8

L = 1^21 ; w = 8

a) when the memory is byte addressable

w = 8 ; L = ( 1 M * 8 ) / 8 = 1M

hence number of bits = log 2 ( 1M ) = log2 ( 1^1 * 1^20 ) = 0 bit

b) when memory is word addressable

w = 8 ; L = ( 1 M * 8 ) / 8 = 1M

number of bits = 0

Pepsi [2]

St. Cyprian of Catharge is a bishop who is often called the African Pope. His martyrdom justified his status and showed his holiness through the judgments of the church. His assertions strongly propose that he is conscious that he is in a situation that he is being slated for intensifying and spreading the factional partition through rigorist inflexibility by his adversaries in Rome. He knew that the advertising line” Feticissimus” together with his troupe would be vending in Rome.

A disgruntled employee can harm a company by launching a computer virus, changing or deleting files, or exposing system password

Setler [38]

Answer:

Threat disgruntled employees

Explanation:

This is a type's threat in a network, why disgruntled employees is a threat?

Because disgruntled employees can implement a plant to damage a company's system when an IT employee be fired.

I t can be difficult to try to protect a system of these threats, Traditionally companies can wait for the less damage, then delete those credentials.

In cloud computing we have IDaaS, where an external company administers the company's credentials, is harder to damage the system in this way.
