Answer:
Selective Repeat protocols
Explanation:
It is better to make use of the selective repeat protocol here. From what we have here, there is a high error rate on this channel.
If we had implemented Go back N protocol, the whole N packets would be retransmitted. Much bandwidth would be needed here.
But we are told that bandwidth is limited. So if packet get lost when we implement selective protocol, we would only need less bandwidth since we would retransmit only this packet.
Answer:
<em>A voltage regulator.</em>
<em></em>
Explanation:
<em>A voltage regulator, controls the output of an alternating current or a direct current (depending on the design), allowing the exact amount of voltage or wattage to be supplied to the computer hardware</em>. This device sometimes uses a simple feed-forward design or may include negative feedback. The two major types of voltage regulator are based on either the electromechanical or electronic components.
<em>The electronic types were based on the arrangement of resistor in series with a diode or series of diodes, and the electromechanical types are based on coiling the sensing wire to make an electromagnet. </em>
When there is an error in the code, the function that should be used is A. float(); weight requires decimals
<h3>When is a code?</h3>
Computer code, or a set of instructions or a system of rules defined in a specific programming language, is a term used in computer programming (i.e., the source code). It is also the name given to the source code after a compiler has prepared it for computer execution.
A float is a number with a decimal place since it is a floating-point number. When greater precision is required, floats are employed. The provided value is transformed into a floating point number by the float() function. In this case, the code is used to calculate the weight of an item and the float function will be vital.

Answer:








Explanation:
Solving (a): To base 10

We simply multiply each digit by a base of 16 to the power of their position.
i.e.


In hexadecimal

So:



This gives:


In hexadecimal

So:


Solving (b): To base 10

We simply multiply each digit by a base of 2 to the power of their position.
i.e.





Solving (c): To base 16

First, convert to base 10
In (b)

Next, is to divide 781754 by 16 and keep track of the remainder





Write out the remainder from bottom to top

In hexadecimal


So:


In b

Next, is to divide 11057389 by 16 and keep track of the remainder






Write out the remainder from bottom to top

In hexadecimal


So:

Solving (d): To octal

Divide 74510 by 8 and keep track of the remainder






Write out the remainder from bottom to top


Divide 67210 by 8 and keep track of the remainder






Write out the remainder from bottom to top
