What is 32-bit: 32-bit tells us that the number of bits that can be processed or transmitted. In another way, you can say that the number of bits that can be used for the single element in a data format.
32-bit is a type of CPU (Central Processing Unit) architecture that can transfer 32 bits of data per clock cycle or you can say that it is the amount of information that the CPU can process every time it performs an operation.

In technical terms, you can say that processors can work with 32-bit binary numbers. If large data appear in front of the computer, then the computer will break down the data into smaller pieces. The word "bit" attached to a number can refer to several things, depending on the context.

The term 32-bit is often applied to the following:

• Microprocessor tells us about the width of the register. A 32-bit microprocessor can only process the 32-bit data and 32-bit memory address. It can never process more than this. 32-bit refer how much information stored in the "registers" of the computer's central processing unit, which is an indication of speed and performance.

• Bus tells about the number of wires in the bus. A 32-bit bus will transmit the 32-bit data in parallel. 32-bit refer the size of data bus through which the processor sends out the information. 32-bit bus can address 4,294,967,296 words (232), which would correspond to 4 gigabytes. The larger data bus enables faster transfer of data to and from storage. Most personal computers today use a 32-bit bus.

• Operating system tells us about the number of bits that can be used to represent the memory addresses. 32-bit can refer to the Operating System; Windows 2000 are true 32-bit operating systems.

• Graphics devices such as a scanner or digital camera- It tells us about the number of bits that are used to represent the pixels of an image. Mostly we use 24 bits for color and another 8 bits for the control information. It can refer to the depth of the pixels on the monitor, which creates the color and the resolution of the images, 32-bit Color (so-called TRUE COLOUR).
• 32-bit can refer to how much information in memory a computer can use.
• 32-bit can refer to the program that uses the 32-bit internal registers and large memory capacity.
• 32-bit can refer to FAT file system, FAT32 allows each disk to be divided into a larger number of clusters (allocation units);
• 32-bit can refer to binary address.
• It can refer to 32-bit chip.
A bit is a tiny electronic signal. In any context, the bigger the bit number, the more powerful, faster, or more colorful the feature.

32-bit processor

The number of bits in a processor tells us about the size of the data types that it can handle and also tells us about the size of its registry. They can effectively handle a small amount of RAM. In the early 1990s, the 32-bit processor was the only processor, which is used in all the computers.

Difference between 32-bit and 64-bit processor:

32-bit Processor64-bit Processor
They can support memory maximum of 3-4GB.They can support memory which is more than 4 GB.
A computer with the 32-bit processor cannot have a 64-bit version of an operating system installed.A computer which has 64-bit processor can have a 64-bit version of an operating system or it can have a 32-bit version of an operating system.
In 32-bit processor, software programs which have a lot of calculations operate slower.In 64-bit processor, the software program which has a lot of calculations can operate effectively, efficiently and faster than the other.
32-bit processors don’t come in different versions.64-bit processors can come in different versions like dual core, quad core, six core, eight core etc.

32-bit operating system

The term 32-bit tells us that how much information can be handled by the processor of the computer. The 32-bit system can access 2^32 memory addresses.
Most of the computers made in the early 1990s and 2000s have 32-bit operating systems. Maximum computers that were developed in the last 20 years were built on the basis of 32-bit architecture. Thus, the computers were designed in such a way so that they can run on the 32-bit processor.
 Ex: Windows 95,98 and XP. They all have a 32-bit operating system.

32-bit Drives

To run the 32-bit system, the compatible drivers are required, which are known as 32-bit drivers. If the device drivers are designed for the 32-bit version of windows, then you cannot run those device drivers on a 64-bit version of windows. Similarly, if the device drivers are designed for the 64-bit version of windows, then you cannot run them on a 32-bit version of windows. You can manually see that whether your windows are 32-bit or 64-bit and the information regarding 32-bit or 64-bit is stored in the control panel of your computer.
