A computer is a programmable electronic device that accepts raw data as input and processes it with a set of instructions a program to produce the result as output.. Cache memory is impo
Mainboard
Among the parts of a computer, the motherboard is the most important component This part is also known as the mainboard, a place that holds all the important components of the machine.It will have slots to connect important components such as CPU, RAM, SSD, GPU, etc In addition, the machine's motherboard can also be attached directly to another part Usually, the screen may refer to a type of metal semiconductor, also known as CMOS.
CPU
The next important part mentioned is the GPU This is an extremely important part of the computer This is where the processor is located, a powerful GPU will help the machine optimize performance extremely well On the market today, there are two popular types of CPU architecture: 32bit and 64bit
In particular, the two manufacturers that have almost a monopoly on the market are AMD and Intel Simply put, the CPU is like the brain of your computer All data access and processing operations on the machine will go through the CPU and then be displayed on the machine's screen.
RAM
RAM (Random Access Memory) temporarily stores data and program information, enabling the computer's operation As a volatile memory, data is lost upon power-off Modern computers utilize various RAM types (e.g., DDR2, DDR3, DDR4), implementing a dual-channel architecture to enhance data processing and bandwidth.
Hard Drive
The hard drive is responsible for storing data and operating systems on a device Two prominent types of hard drives are HDDs and SSDs, each with distinct advantages and drawbacks HDDs are more affordable but offer slower read, write, and processing speeds compared to SSDs, whose performance is significantly enhanced.
GPU
Among computer parts, it is impossible not to mention the GPU Graphics card, also known as the graphics processor, links between the computer and the display screen The effect of the graphics card is to support the processing of all data related to images and videos and output to the computer screen Following the strong development of titles, games, graphics software, etc., the requirements of the graphics card when used will have higher parameters, serving the computer's graphic tasks well than.
Power supply
The PSU (power source unit) is a crucial component responsible for providing stable power to the computer, ensuring it can operate at its peak Without a reliable PSU, the computer's performance will suffer, potentially leading to operational issues and system instability.

What is cache memory?
Cache memory is a special high speed primary memory
Cache memory is important as it helps to increase the processing speed of CPU by making current program and data available to CPU at rapid rate
Cache memory acts as a buffer between CPU and main memory by storing program or data needed in current execution as well as temporary data frequently needed in current computation.
Why is it necessary?
The speed of the CPU is generally faster than main memory's speed This results in slow down in processing speed of the CPU as main memory is not able to provide data and instruction as per CPU's processing rate So a technique was developed of using a small, high speed cache memory and place it in between CPU and main memory
Cache memory access time is almost close to CPU cycle time Thus cache memory helps in increasing the performance of the computer.
Cache memory stores the portion of programs currently getting executed in CPU and any temporary data needed for computation
It acts as a buffer between CPU and main memory.
This is the reason cache memory is important and highly needed.
The above CPU and main memory speed disparity is popularly known as Von-neumann bottleneck.Thus cache memory is needed to eliminate this problem of speed disparity.
Compare Cache and RAM?
What is computer system
Is a collection of entities(hardware,software and liveware) that are designed to receive, process, manage and present information in a meaningful format.

Conclusion
Computers have and continue to play an indispensable role in modern life They not only help us solve complex problems but also open the door to new discoveries in many fields such as science, education, medicine and art Although computers can cause some problems such as over-dependence or security issues, the benefits they bring far outweigh them In general, computers are important tools that help improve the quality of our lives and work In the future, we can expect constant progress in computer technology, opening up new possibilities and improving our lives for the better.
