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.
One can structure of a table change in sql and the general types of changes that are possible is that:
- One can use the MODIFY STRUCTURE to alter the structure of the current table that one is in and this is done by adding or deleting fields.
- One can also change or alter a field name, width, or that of the data type and this is done by Issuing the MODIFY STRUCTURE command that tends to opens the Table designer, an interactive place in which a person can create or change the structure of a table.
<h3>How can we modify the structure of a table in SQL?</h3>
The SQL ALTER TABLE command is known to be the tool that is often used to alter the structure of an existing table.
Note that it is one that can helps to add or delete columns, make or destroy indexes, alter the type of existing columns, and others.
Hence, One can structure of a table change in sql and the general types of changes that are possible is that:
- One can use the MODIFY STRUCTURE to alter the structure of the current table that one is in and this is done by adding or deleting fields.
- One can also change or alter a field name, width, or that of the data type and this is done by Issuing the MODIFY STRUCTURE command that tends to opens the Table designer, an interactive place in which a person can create or change the structure of a table.

Answer:
Computers are now a days the very important part of each department as well as homes. All people are somehow using computers for their respective needs. As technology always has the negative impacts along with the positive ones so, computer do have some crucial points when taking about students specially.
Following are listed some acts that add to the negativity of computer's usage.
- Excess use of computers by students while solving mathematical problems lead them to rely totally on the computer. Students don't tend to calculate by their own instead they use computerized calculators for their ease and hence they start lacking even in basic calculations in normal routine also.
- Computers may impact students routine in such a way that they don't concentrate on their studies while having extreme interest in video games and their favorite seasons and other activities.
- Using computers more than a certain limit effects eyesight badly. This is the reason today most of the teenagers use spectacles in normal routine.
