Using the cache can increase the speed of the computer because the 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.

How to implement jump in php header: 1. Use "Header("Location:$url");" syntax to implement jump; 2. Use if judgment to implement jump, with jump statements such as "if($_COOKIE[" u_type"]){ header('location:register.php'); } else{ setcookie('u_type','1','86400*360');".

Characteristics of cache: A one- or two-level high-speed, small-capacity memory set between the CPU and the main memory. The information is naturally lost when the computer is powered off. Characteristics of ROM: it can only read data from the memory, but cannot write information into it. The data will still exist after the computer is powered off. Characteristics of ram: it can read data from the memory and write information to the memory; it is used to store commands, programs and data required to run the program; information is naturally lost when the computer is powered off.
