Differenciate between foreign key and primary key in database.

Answers

Answer 1

Answer:

A primary key is utilized to guarantee the information in the particular segment is interesting. A foreign key is a section or gathering of segments in a social data set table that gives a connection between information in two tables. It particularly recognizes a record in the social information base table.

Answer 2

A primary key is utilized to guarantee the information in the particular segment or which we may say as data is interesting. In contrast, a foreign key is a part of a section or gathering of features/data in a social and whole data set table that gives a connection between the information of two tables.

It particularly recognizes a record in the social information base table of the whole database system.

The PRIMARY KEY constraint is a unique entity that uniquely identifies each record in a table.

The FOREIGN KEY constraint prevents works that would destroy the link between two/multiple tables.

how to add two binary numbers together (preferably 45 or under words)

Answers

The binary addition operation works similarly to the base 10 decimal system, except that it is a base 2 system. The binary system consists of only two digits, 1 and 0. Most of the functionalities of the computer system use the binary number system. The binary code uses the digits 1’s and 0’s to make certain processes turn off or on. The process of the addition operation is very familiar to the decimal system by adjusting to the base 2.

A example is
0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 =10
I hope this helps man

0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 = 0
1 + 1 + 1 = 1
1 + 1 + 1 + 1 = 0

a man named Billy bob jones picked up a phone call that said he bought something for 1,000,000 dollars and the man in an Indian accent asked if he wanted a refund and of course, Billy bob jones was old and not very smart so he said yes and gave the so-called kind man his credit card. Oh, how not very smart he was.

immediately after he started getting bombarded with emails from his bank telling him that purchases were being made and poor old Billy bob jones

just sat there in stress and everything the bank was saying made no sense but he knew someone and his name was

Kitboga who would help him

and he hackered the sad Indian scammer and took his location and then before destroying the Indian call center he ratio + L boozed them one last time

Explanation:

There is a similar scam alert from someone who shared his/her story here too. Its exactly the same.

I received a call from a number 8057 6284 (+65 prefix was not present). The caller was a male and spoke in Mandarin with a Malaysian accent. He started by saying that he changed his handphone number so his purpose of the call is to update me about it. Then i know who is he. He said you guess la. i replied no, i don’t know. He said u think harder la. i repeated at least 2 times that i really don’t know who are you, and maybe he called the wrong number. Again, He REMAINED INSISTENT THAT WE KNEW EACH OTHER and went on saying YOU DON'T REMEMBER? We always talked on the phone one! You think harder la! Throughout the call, HE REFUSED TO REVEAL HIS NAME AND KEPT PROMPTING ME TO GUESS and guess.

i refused to give him any name after umpteen times of “you guess who am i la, you think harder, we speak before.” so he said “i have another incoming call” and he hung up immediately.
