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: An operating system(OS) is an interface between the hardware and the user. An OS is built so that it could support other software. OS is a system software which is used to support other application softwares.
Explanation:
An operating system handles all the hardware of the system and allows users access to those hardware components with the help of application softwares.
An OS consist of many libraries and APIs which allows programmers to write and execute codes. There are many types of OS such as real time, multitasking, multi programming OS.
The OS is responsible for allocating memory, managing the hardware, distributing resources across different processors in an distributed system.
So all these features makes them different from application software. The OS is responsible allocating memory and hardware resources to these softwares.
The answer is A it’s the one that sounds right
