String -The string data type can hold multiple characters as a sentence or word

like “Hello” and a string needs the quotation marks around the word

so that the program knows that that is the word to be used string is generally

understood as a data type and is often

implemented as an array data structure of

bytes (or words) that stores a sequence of elements, typically characters,

using some character encoding.

Single -Holds signed IEEE 32-bit (4-byte) single-precision

floating-point numbers ranging in value from -3.4028235E+38 through

-1.401298E-45 for negative values and from 1.401298E-45 through 3.4028235E + 38

for positive values. Single-precision numbers store an approximation of a real

number.

Use the Single data type so that you can contain floating-point values

that do not require the full data width of Double. In some cases the most common language runtime might be

able to pack your Single variables

closely together and save memory consumption. This is what businesses want from

there I.T workers to make the code efficient and quick.

Boolean -Boolean is a part of a bigger group

of algebra that is used to making a True/False statement. True will be written

as the number 1, whereas false will be written as the number 2. Boolean can be

written in both algorithms and coding. Boolean was created by the English

mathematician and computer pioneer George Boole so this is why it’s called the

Boolean theory.

A Boolean is composed of operators

such as and, or, not and or. Booleans are used in programming and today in

internet search engines. Boolean expressions are the result in the value of

either true or false. As mentioned above, a user can use

Boolean searches to help locate more exact matches in internet searches.

Integer- This is a quite common data type. You also may find integers in math and

it means the same thing a whole number. Integer is very useful in programing as

numbers are used quite a lot in programing overall. Programmers have to pick a

certain data type for that certain character so that they don’t waste a lot of

memory.

Double-The

float type allows you to store single-precision floating point numbers, while

the double keyword allows you to store double-precision floating point numbers

– real numbers, in other words. Its size is typically two machine words, or 8

bytes on most machines. This is the decimal point number data

type you would use this for mathematical equations like division

because division problems are likely to have a decimal point in the answer.

Byte-A byte is the smallest unit of addressable storage

although a bit is smaller than a byte, a single bit cannot be addressed

directly; we always deal with groups of bits and a byte in the smallest group

of bits that can be physically addressed. However, once we have addressed a

byte, we can then examine the individual bits within it using the logic

operators AND, OR, NOT and XOR. On most systems a byte is exactly 8 bits in

length. The reason for this is simply that we can represent any 8-bit value

using a convenient two-digit Not all programming languages utilise a byte data

type as such.
