What is the difference between register and buffer?

The main difference between register and buffer is that the register is a temporary storage area in the processor that allows data to be transferred faster while the buffer is a temporary storage area in main memory that holds data before it is used.

A register is a fast memory location built into the processor. Also, the total number of registers available on a computer depends on the architecture of the computer and varies from machine to machine. In fact, more registers help increase processor performance. On the other hand, a buffer is a main memory location that holds temporary data for use by a process or device.

What is Registry

A registry is a small, fast storage unit. The processor stores temporary data in registers. This allows you to store and transfer data from one location to another. Some registers can perform read-only operations, while others can perform write-only operations. Also, the sizes of the registers can vary depending on the architecture of the computer. A register stores the received data and sends it to the required location according to the instructions of the CPU.

Also, there are various types of registers available in a computer system, and they perform various operations. Some of them are the following.

Counter program (PC) – Contains the address of the following instructions that must be executed.

Instruction Register (IR) – Contains the address of the currently executing instruction

Stack Pointer Register (SPR) – Manages the stack

Accumulator Register (AX) – Stores intermediate arithmetic and logical results.

Data Register (DR) – Holds numerical values ​​of arithmetic operations.

Address Register – Contains addresses of instructions that indirectly access primary memory.

Status Register – Holds the state of the instructions (whether to execute the instruction or not)

General Purpose Register – Stores data and addresses

Floating Point Register – Stores floating point values

Vector Registry – Contains the data required for vector processing

what is the buffer

A buffer is an area in main memory for storing data during input and output data transfers. A buffer is useful when moving data between processes within a computer.

For example, we use a buffer when we download a video or audio file from the Internet. About 20% of the file is buffered. So start playing. While the file is playing, the computer continuously downloads the remaining part of the file. The new section is also buffered. Similarly, the file is played with the help of the buffer, not directly from the Internet. Prevent file from skipping or stopping due to high network traffic.

Difference Between Log and Buffer

Definition

Register is a small amount of fast storage which is a quick access place available on a computer’s CPU. A buffer or data buffer is a physical memory storage region that is used to temporarily store data while it is moving from one place to another. Thus, this is the main difference between register and buffer.

Location

Also, the registers are in the CPU, while the buffer is in main memory.

Use

A register allows the processor to temporarily store data for processing and transfer from one location to another. Buffer helps to store data temporarily before using it. Hence, this is another difference between register and buffer.

conclusion

The main difference between register and buffer is that a register is a temporary storage area in the processor that allows data to be transferred faster, while a buffer is a temporary storage area in main memory that holds data before it is used.
