The 7-bit ASCII code for the character ‘&’ is: 0100110 An odd parity check bit is now added to this code so 8 bits are trans

mitted. What will be the transmitted bit sequence for the ASCII character ‘&’? If odd parity check bits are used when transmitting ASCII codes, which of the following received bit sequences are not valid? Explain briefly how you reached your answer. a.01001000 b.01011110 c.01111111 d.11100111

Answer

First part:

The transmitted 8-bit sequence for ASCII character '&' with odd parity will be 00100110. Here leftmost bit is odd parity bit.

Second part:

The invalid bit sequence are option a. 01001000 and d. 11100111

Explanation:

Explanation for first part:

In odd parity, check bit of either 0 or 1 is added to the binary number as leftmost bit for making the number of 1s in binary number odd.

If there are even number of 1s present in the original number then 1 is added as leftmost bit to make total number of 1s odd.

If there are odd number of 1s present in the original number then 0 is added as leftmost bit to keep the total number of 1s odd.  

Explanation for second part:

A valid odd parity bit sequence will always have odd number of 1s.

Since in option a and d,  total number of 1s are 2 and 6 i.e. even number. Therefore they are invalid odd parity check bit sequences.

And since in option b and c, total number of 1s are 5 and 7 i.e. odd numbers respectively. Therefore they are valid odd parity check bit sequences.

Virty [35]

Answer:

Replace the power supply

Explanation:

Usually, Capacitors burn up because of different factors.

- Exceeding operation voltage

- High Inverse voltage if is an electrolytic capacitor.

A tentative answer could be the battery, but usually the batteries damages are because wear out of them, that is, cycles of charging and discharging, a problem that could arise in the battery is related with the charge protection, this circuit cares that the battery only get the charge that it needs, in Li-po batteries is 3.7V, in some laptops is 24 V, if so the battery could explode or leaking acid.  

The mother-board is the "brain" and the Random Access Memory (RAM), they consume a lot of energy and usually heat up, but doesn’t produce increasing of voltage and its feed it by voltage regulators.

The only valid option is the power supply because the energy comes from a rectifier (made with diodes) and a voltage regulator that step-down the DC voltage output if by any chance the voltage increase or a diode burns up in the power supply the coupling capacitors or input capacitors in the computer will fail.

Answer the question ASAP please
RUDIKE [14]

Answer:

Shows the programming checking if num1 is greater than num2

Explanation:

So num1 and num2 are inputs

for you to code this you would need to put

num1=int(input("What is your first number? ))

and the same for num2 except change num1 for num 2 and first for second

When the input is completed, the computer will check if num 1 is greater than num2

it will do this by using a code something like:

if num1>num2:

    Print("Your first input was greater than your second")

But in this example if it greater it just ends

But if it was less than you would put

if num1>num2:

    Print("Your first input was greater than your second")

elif num1<num2:

    Print("Your first input is less than your second")

So basically this code shows the computer checking if one number is greater than the other or not

Were Al Zink’s actions that of someone trying to be an invisible Sponsor
AlexFokin [52]
Al Zink actions differentiate him as trying to take an invisible role as a project sponsor. That is, Al Zink does not do his chosen role and accountability as the lead project sponsor. Though, in dissimilar occasions, Al Zink is seen to evade making a serious choice regarding the development of the project. Consequently, as a project sponsor, it is his accountability to deliver clear steps in increasing the project, recover every step of project development and balance the start of the project.

What is segmentation and paging?
iogann1982 [59]

Over the years, operating systems have sought to be more efficient, which is why it is vital that the use of main memory such as ram be as intelligent as possible, so that operating systems are more efficient.

Segmentation is a process of dividing the program into logical units, such as sub functions, arrays, variables, etc., making it possible to have processes divided into pieces so that it is easy to access each of the processes that this leads to its execution. Segmentation allows the programmer to contemplate the memory as if it had several address spaces or segments. References to memory consist of an address of the form segment number - offset.

Pagination is a technique where memory space is divided into physical sections of equal size, called page frames. The programs are divided into logical units, called pages, that are the same size as the page frames. In this way, an information page can be loaded in any page frame. The pages serve as an information storage unit and transfer between main memory and auxiliary or secondary memory. Each frame is identified by the frame address, which is in the physical position of the first word in the page frame.
