Day 1 Computer basics, day Computer BasicsComputer Basics 1. Why learning computer basics? The role of programming languages: commands that humans use to make machines understand and act. It is similar to English in human society. Relationship: Computer Hardware-Operating System (OS)-software (finished programming language, learning results ). Hardware: There is an operating system on the hardware layer for

Day 1: Project Construction, Day 1 Project Construction I. Preface 1.0. Since I have not written about the general crawler framework, I searched around and found a lot of information. Here I used the framework model introduced by a great god. I forgot the reference address, so I will not post it here. 2.0 the previously mentioned Verification Code module also stopped, and then we will talk about it together

to a 48-bit register named GDTR. This is a very special 48-bit register, and can not be used with our usual MOV instructions to assign value. When assigning a value to it, the only way to do this is to specify a memory address, read 6 bytes (i.e. 48 bits) from the specified address, and assign the value to the GDTR register. The command to complete this task is LGDT.The lower 16 bits of the register (that is, the first 2 bytes of memory), is the upper limit of the segment, which equals "the num
