Answer:
Select commands would return all the rows and columns in the table.
Explanation:
In the database management system, it consists of one or more table. To handle this table it provides the concept of SQL(Structured Query Language). It is a programming language that design, manage, store data into the relational database. It is case sensitive language. In the SQL many commands used for handle table data, it returns all rows and columns from the table.
Syntax of select command can be given as:
Select * from tablename;
Example:
select * from ProductCategory;
returns all the data from the table.
In select command, we will also return select data by using condition
SELECT column1 [, column2, ...]
FROM tablename
WHERE condition
In the conditional clause we use these operators that can be given as:
= Equal, > Greater than, < Less than, >= Greater than equal to, <= Less than equal to, != Not equal to.
An actual parameter in a method call, or one of the values combined by an operator
Answer:
Each description of a PC needs to clarify how the PC handles data: numbers, text, pictures, sound, films, directions.
Using bits to represent data implies that the computer has to use a lot of memory since every character has a group of bits representing it.
The PC is an electronic gadget. Every one of its wires can either convey electric flow or... not convey current. Thus, similar to a light switch, it sees just two states. Incidentally, this is sufficient to make the entire thought work. Indeed, any framework that can speak to in any event two states can speak to data. Take, for instance, the Morse code that is utilized in telecommunication. Morse is a sound transmission framework that can convey a short signal (spoke to by a dab) and a long beeeeeep (spoke to by a scramble). Any letter or number can be spoken to by a mix of these two images. Snap here to see a Morse interpreter.
Explanation:
Essentially with PCs. To speak to a number, we utilize the parallel number-crunching framework, not the decimal number framework that we use in regular day to day existence. In the double framework, any number can be spoken to utilizing just two images, 0 and 1. (Morse is nearly, yet not exactly (because of the delays between letters) a paired framework. A framework firmly identified with Morse is utilized by PCs to do information pressure (more about this later).
Sorry I don’t know the answer I am really sorry
Well thats false. They are only notes, not extra details.
