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.
Answer:
The speed or quality was different.
Explanation:
The new ram that he installed most likely had a different rate, or was a different quality than the old ram.
Answer:
Singleton pattern is the pattern for design that is build using the global variables which creates a lot of drawback in the designing. Singleton pattern are considered with the global variable and thus cannot be bound into single unit which complexes the components in design.
They have a loose coupled variables in design and also does not show the property of the multi-threading .These feature are responsible for the decrement in the performance and thus are not highly preferred choice for the pattern.So, it is known as the "anti- pattern".
The automotive system that connects the engine and the transmission to the wheels is c (c) the steering system
