<u>Some recommend way to prove the authenticity of an email:</u>

The coworker as truthful to the company or organization he or she has to check where the same mail is sent long back to the same sender.

If search on emails sent item if he sends it will be well and good. Some time backup the mail will be help to proven authenticity of an email.

Sometimes once mail is downloaded into ms-outlook or lotus domino some time mail persists in the mail server.

He or she can coordinate with the mail server administrator to possible get a log file of sending mail and he can proceed as a record to management.

Write a loop that sets newScores to oldScores shifted once left, with element 0 copied to the end. Ex: If oldScores = {10, 20, 3

Anarel [89]

Answer:

The code to this question can be given as:

Code:

int lastVector = newScores.size() -1; //define variable lastVector that holds updated size of newScores.

newScores = oldScores; //holds value.

for (i = 0; i < SCORES_SIZE - 1; i++) //define loop.

{

newScores.at(i) = newScores.at(i+1); //holds value in newScores.

}

newScores.at(lastVector) = oldScores.at(0); //moving first element in last.

Explanation:

In the given C++ program there are two vector array is defined that are "oldScores and newScores". The oldScores array holds elements that are "10, 20, 30, 40".
In the above code, we remove the array element at first position and add it to the last position. To this process, an integer variable "lastVector" is defined.
This variable holds the size of the newScores variable and uses and assigns all vector array elements from oldScores to newScores. In the loop, we use the at function the removes element form first position and add in the last position.
Then we use another for loop for print newScores array elements.

A digital computer has a memory unit with 16 bits per word. The instruction set consists of 72 different operations. All instruc

OLga [1]

Answer:

a. 7 bits b. 9 bits c. 1 kB d. 2¹⁶ - 1

Explanation:

a. How many bits are needed for the opcode?

Since there are 72 different operations, we require the number of bits that would contain 72 different operations. So, 2ⁿ ≥ 72

72 = 64 + 8 = 2⁶ + 8

Since n must be an integer value, the closest value of n that would contain 72 different operations is n = 7. So, 2⁷ = 128

So, we require 7 bits for the opcode.

b. How many bits are left for the address part of the instruction?

bits left = bits per word - opcode bit = 16 - 7 = 9 bits

c. What is the maximum allowable size for memory?

Since there are going to be 2⁹ bits to addresses each word and 16 bits for each word, the maximum allowable size for memory is thus 2⁹ × 16 = 512 × 16 = 8192 bits.

We convert this to bytes

8192 bits × 1 byte/8 bits = 1024 bytes = 1 kB

d. What is the largest unsigned binary number that can be accommodated in one word of memory?

Since the number go from 0 to 2¹⁶, the largest unsigned binary number that can be accommodated in one word of memory is thus

2¹⁶ - 1

The engine that runs the computer. Small computers have one, while larger computers may

Dmitrij [34]

Answer:

CPU.

Explanation:

A processor, also known as a Central Processing Unit, is a piece of hardware in a computer that performs basic operations and control when executing program code.

Processors are usually made as integrated circuits closed in a hermetic casing, often with gold-plated leads (used for resistance to oxidation) and in this form they are called microprocessors - in common speech the terms processor and microprocessor are used interchangeably. The heart of the processor is a single crystal of silicon, on which a series of semiconductor layers have been applied by means of photolithography, forming, depending on the application, a network of several thousand to several billion transistors. Its circuits are made of metals with good electrical conductivity, such as aluminum and copper.
