In this question the option b,c, and d are correct.
Explanation:
A (DBMS) stands for a database management system. The DBMS is a software package that is used for crate, update, and delete. The database uses the SQL which stands for the structured query language. It is a programming language that uses the queries. These queries are used to providing many operations in the database like crate table, update table, join table, create a view of the table, etc. In the database, we can view the code of the join table and is also used to hide the complexity of retrieval operations, it can help in the update the table in a single statement.
Answer:
d. methodical step-by-step procedure for solving problems.
Explanation:
It is a set of instructions or a step-by-step methodological approach or process that helps solve simple or complex problems. Let’s say you want to count the number of people in a hall. You can count them one at a time with your finger and count from 1. You can express this algorithm of counting the number of people in that hall in form of a mathematical or computer pseudo code.
Answer:
10010101 + 00101110 = 1 1 0 0 0 0 1 1 , 10010101 - 00101110 = 0 1 1 0 0 1 1 1,
01101101 + 01110011 = 1 1 1 0 0 0 0 0 , 01101101 - 01110011 = - 1 1 1 1 1 0 1 0
Explanation:
10010101 + 00101110 = 1 0 0 1 0 1 0 1
+ <u>0 0 1 0 1 1 1 0</u>
<u>1 1 0 0 0 0 1 1</u>
In binary, 1 plus 0 is 1, but 1 plus 1 ( which conventionally is two) is divided by 2 and the result is carried-out, while the remainder is used as the answer.
10010101 - 00101110 = 1 0 0 1 0 1 0 1
- <u>0 0 1 0 1 1 1 0</u>
<u>0 1 1 0 0 1 1 1</u>
Subtraction in Binary calculation, a borrow to a 0 value is equal to two, this law is implemented in a case where 1 is subtracted from 0 ( which is impossible).
01101101 + 01110011 = 0 1 1 0 1 1 0 1
+ <u>0 1 1 1 0 0 1 1</u>
<u>1 1 1 0 0 0 0 0</u>
<u />
01101101 - 01110011 = 0 1 1 0 1 1 0 1
- <u>0 1 1 1 0 0 1 1</u>
- <u>1 1 1 1 1 0 1 0</u>
At the end of the subtraction, if the value subtracted from in less than the subtracted number, two is borrowed and the result becomes negative or signed.
