60G refers to a hard disk, which is an iron box-like thing. G is usually used to indicate the easy size. The movie files we watch exist here (there is another type called floppy disk, which has a small size and a small capacity. The simplest way to distinguish is to keep the hard disk, and floppy disk that can be broken is)
500M (it should be said to be 512M) refers to memory. All running programs are read from the hard disk and stored in memory. When the CPU wants to process, it will take it from the memory. If the data that the CPU wants to process is not in the memory, it will direct the reading from the hard disk to the memory before processing. Therefore, if the memory is too small, the data that the CPU wants to process will often not be found in the memory, so it will often read the hard disk. Therefore, if the memory is too small, you will see the hard disk lights flashing constantly. This is the reason.
Currently, the general memory is DDR memory
60G This G is not a pronunciation, but a pronunciation of "born", which is the pronunciation in English letters.
M This is a sign of thought
1GM=1024MG
This MG is called Zhao, what do you think of this GM? Just recite "Story B"
It was called wrong, it should be 1GB=1024MB
G reads G, M, reads B, reads B, is gigabyte, B means byte
That is 1G byte = 1024 megabytes
Hard disk speed refers to the amount of data transmitted per unit time of the hard disk.
Some reasons affecting the speed of the hard disk are response time (referring to the time when the hard disk receives the command to the start of the action), seeking time (referring to the time from the start of the head to the finding of the required sector) rotation speed (referring to the speed of the disk rotation. In theory, the faster the disk rotates, the stronger the ability to read data, and the faster the speed. Currently, mainstream desktop hard disks are all at 7200 rpm), cache size (because the hard disk is much slower than the memory, the hard disk will pre-read some data from the disk and put it in the cache. If the data to be called by the system is in the cache, the cache will be read first. The data in the cache is much faster than the disk reading, so if you can often read data from the cache, you will feel that the hard disk speed is much faster. Therefore, the larger the cache, the higher the probability of pre-stored data being accessed, so you will feel that the speed is also faster. Now the cache usually has 2M and 8M. It is recommended to choose 8M, which has much higher performance than 2M), interfaces (there are IDE, SATA and SATAII. The newer the interface, the faster the theoretical transmission rate), and internal transmission rate (usually this is not a problem, because the bottlenecks are on the external interface, so you don’t need to consider this)
