Regarding memory capacity, what is memory capacity

First of all, the knowledge that is not explained upstairs is that the internal calculations of the computer are all done in binary mode, and the carry of memory capacity is of course no exception, such as 2 10 (2 to the 10th power) = 1024.

Then, from B to KB, it is actually 1KB=2 10B=1024B, and similarly, 1MB=2 10KB=1024KB, and the same is true for the carry relationship between GB and MB

B is what we call bytes, a byte can be divided into 8 bits (bits), English letters in memory only occupy 1 byte, that is, 8 bits, but there are too many Chinese characters (unlike the English alphabet only 26, plus a variety of symbols are only about 200), so a Chinese character occupies two bytes, that is, 2b, so there are 2 to the 16th power of different values to represent Chinese characters, you can calculate, this number is absolutely enough.

In fact, this kind of stuff is very basic, I wish you a happy learning! Hehe!

1mb=1024kb

1kb=1024b

One kanji accounts for two Bs, and you can count the rest yourself.

Actually, this is only a rough algorithm.

A Chinese character is two bytes, 1024 bytes is 1k, 1024k is 1m, and 1m is what we usually call a cover! 1024m is 1g

One kanji accounts for 2kb

One letter accounts for 1kb

Generally 4g, 8g, 16g. Today's computers can install at least 2 memory modules, so users who want to upgrade their own memory can upgrade up to 32G, and the current largest Asgard memory has a single memory capacity of up to 32G, so the case memory of the computer can reach 64G.

3But not all computers support that large memory, we can enter cmd in the run bar of the start menu and click enter, and then enter the command wmicmemphysicalgetmaxcapacit and press enter, then a string of numbers will pop up, which is the maximum memory supported by the computer.

Memory is one of the important components of a computer, also known as internal memory and main memory, which is used to temporarily store computing data in the CPU and exchange data with external memory such as hard disks. It is the bridge between the external memory and the CPU, and all the programs in the computer are running in memory, and the strength of memory performance affects the overall performance of the computer. As soon as the computer is running, the operating system will transfer the data that needs to be calculated from the memory to the CPU for calculation, and when the calculation is completed, the CPU will send the result.

The operation of memory also determines how fast or slow the computer as a whole runs.

A memory module consists of a memory chip, a circuit board, a gold finger, and other parts.

2g in general.

Newly equipped mid-range and above computers are generally 4G memory.

The high-end ones are generally 6G, that is, 3 strips of 2G.

The memory module consists of 3

channel memory, and a few are configured with 8G memory.

In order to be able to run smoothly in the next 1-2 years.

Software, along with 4G RAM is required.

2GB is fine, there are very few 1GB computers nowadays, if you only use XP system, your bottom configuration can be 1GB, if you want to upgrade to Vista later, you can have 2GB of RAM.

In general, the computer has a home memory capacity of 4G, and there are games that require 8G, which is the most basic.

Memory capacity refers to the storage capacity of the memory module, which is the key parameter of the memory module, and the memory capacity is the same as the storage capacity unit such as hard disk and floppy disk, and their basic units are bytes (b).

Memory capacity can be seen as a bridge between the memory controller and the CPU, and the memory is equivalent to a "warehouse". The capacity of memory determines the size of the "warehouse", and the speed of the memory determines the width of the "bridge", both of which are indispensable, which is "memory capacity" and "memory speed".

This is the method of calculating memory, and there is a premise that it is based on the CPU.

The bit width of the data bus is now generally 64 bits, and this bit width is called the physical bank...

2.Memory 1rx4 represents a 64-bit memory, and x4 represents the number of bits per memory particle. From here, we can easily know that the number of memory particles is:

64 4 = 16 pieces. If it is 2rx8, the memory particles are: 64*2 8=16, and 2rx4 is 64*2 4=8 sharp socks.

3.So whether it's 1rx4, 2rx4 or 1rx8, 2rx8, the meaning of the representation can be understood as the number of memory particles of memory. Instead of single-sided or double-sided memory.
