Using cache can improve the running speed of the computer. This is because Cache shortens the waiting time of the CPU. Cache is a small but high-speed memory located between the CPU and the main memory DRAM. The function of Cache is to increase the rate of CPU data input and output; Cache has a small capacity but fast speed, while the memory speed is low but has a large capacity. By optimizing the scheduling algorithm, the performance of the system will be greatly improved.

Using cache can improve the running speed of the computer. This is because Cache shortens the waiting time of the CPU.
Cache memory is a high-speed cache memory in a computer. It is a small but high-speed memory located between the CPU and the main memory DRAM (Dynamic Random Access Memory). It is usually composed of SRAM ( Composed of Static Random Access Memory (static memory).
The function of Cache is to increase the rate of CPU data input and output. Cache capacity is small but fast, memory speed is low but capacity is large. By optimizing the scheduling algorithm, the performance of the system will be greatly improved, as if the storage system capacity is equivalent to the memory and the access speed is similar to the Cache.
#Cache is a small-capacity but high-speed memory located between the CPU and the memory. The speed of the CPU is much higher than that of the memory. When the CPU directly accesses data from the memory, it has to wait for a certain period of time. The Cache can save a part of the data that the CPU has just used or recycled. If the CPU needs to use this part of the data again, it can Called directly from the Cache, this avoids repeated access to data, reduces the waiting time of the CPU, and thus improves the efficiency of the system
Classification:
Cache again It is divided into L1Cache (level one cache) and L2Cache (level two cache). L1Cache is mainly integrated inside the CPU, while L2Cache is integrated on the motherboard or CPU.
Technical analysis:
One of the development trends of PC systems is that the CPU frequency is getting higher and higher, the system architecture is becoming more and more advanced, and the structure of the main memory DRAM and access times improved more slowly. Therefore, Cache technology is becoming more and more important, and Cache is getting bigger and bigger in PC systems. The majority of users have regarded Cache as an important indicator when evaluating and purchasing PC systems. Cache can be used as a match to adjust the gap between devices with large differences in transmission speed, or in other words, it is the transmission channel of these devices. Cache technology is required in display systems, hard disks and optical drives, as well as network communications.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
