what is stereolithography machine

I recently learned the HTTP protocol and found that I can write a program to simulate user registration, post and other programs !! I searched the internet and found that this kind of program is called a Web page registration machine. users can be self-registered in a crazy way, or even publish advertisement posts, all of which are directly completed by a program. in essence, it

What you're doing when you code: talking about the nature of programming (a) state machineThis semester studied two interesting lessons, theory of computation and distributed System, a low a high total of two levels of the branch, but unexpectedly found the two theoretical overlap-that is the state machine. In theory of computation, the DFA, NFA, Turing

A process is a running activity of a program with certain independent functions about a data set.The difference between a process and a program:1, the program is an ordered set of instructions, is a static concept, its ability does not have any meaning of operation. The process is a process in the process of processing
