What is memory? What is function of a memory card?
With continuous development of modern technology, functions of many electronic products are becoming more and more powerful, such as computers, TVs, mobile phones, learning machines, story machines, etc., all of them have memory that can store a lot content to play. Especially for computers, memory is an indispensable accessory of computer equipment. So, today I will share with you what is memory? What is function of a memory card?
What is memory
1. To sum up in professional terms, memory is one of most important components of a computer and a bridge for direct communication with CPU. When we work on a computer, programs we use run in memory, so size of memory directly affects speed of computer. Memory is also called internal memory, and its function is to temporarily store data in CPU and exchange data with external memory such as hard drives at same time. As long as computer is running, CPU will store data in memory for work, and speed of memory will directly affect stability of computer. Memory consists of circuit boards, golden fingers, memory chips and other parts.
2. You might find this complex after reading technical terms above, but it's actually very easy to generalize. Memory is storage, not hard drives and other storage that is faster than regular hard drives and has flash technology. But only disadvantage is that when power is turned off, all data in memory will be cleared, since data stored in memory needs to be saved at any time. Generally speaking, larger memory, faster data transfer. Therefore, when many people use computer, they always talk about computer card. It is likely that hard drive of computer itself is too slow, and there is no space for external memory storage.
The role of memory card
1. Simply put, role of memory in a computer is equivalent to a bridge. The main function is to store data on hard disk motherboard and exchange data between processors. With continuous development of hardware technology and computer software, memory cards have replaced all data storage in general. Therefore, we usually say that amount of computer memory is total amount of computer memory.
2. When people read and write data to memory or memory card, if power is suddenly cut off, data is completely lost, because data read by CPU comes from memory even when computer is turned on, so current technology cannot be restored at all. Now there is no main memory on computer motherboard, and all data on external memory must pass through memory to play role of a flash drive.
The above is what Xiaobian introduced to you today about introduction of memory and memory card function. I believe that after you understand above, you will know more about computer memory. In normal computer operations, we can store some data on D drive or E drive so that it does not take up too much memory in hardware.
