It depends on the context. Each database and computer language define an "integer". In the C language an integer is defined by the hardware. It can vary from 2 to 8 bytes or more.
A plain integer variable in C under windows is 2 bytes in 16 bit windows, and 4 bytes in 32 bit windows.
4 bytes
There are 8 bytes in a double
Usually four bytes.
The number of bytes an integer variable can take depends on the programming language and the system architecture. Typically, in languages like C and C++, an int usually takes 4 bytes (32 bits) on a 32-bit or 64-bit architecture, while a short takes 2 bytes and a long can take 4 or 8 bytes depending on the system. In Python, integers can vary in size and can take more than 4 bytes, depending on their value, as they are dynamically allocated. Always check the specific language documentation for precise details.

The number of bytes required to store a number in binary depends on the size of the number and the data type used. For instance, an 8-bit byte can store values from 0 to 255 (or -128 to 127 if signed). Larger numbers require more bytes: a 16-bit integer uses 2 bytes, a 32-bit integer uses 4 bytes, and a 64-bit integer uses 8 bytes. Thus, the number of bytes needed corresponds to the number of bits needed for the binary representation of the number.
4 bytes are enough to represent any integer in a range of approximately -2 billion, to +2 billion.
Variables are means for location in memory used by a program to store data. The size of that block depends upon the range over which the variable is allowed to vary. For example, on personal computer the size of an integer variable is two bytes, and that of a long integer is four bytes. A variable region is temporarily remember a number or string value, such as covered by the program. To identify the variables, you have a name unique to every single variable. This is called a variable name. Before using a variable, use variables to what is called a variable declaration that you have to reveal the names and data types that can be stored in the variable variable.
