In-depth understanding of types and computer systems
In C #, there are two types: Value Type and reference type.
1. Value Type and reference type
An in-depth understanding of these two types is very important. The interviewer will test the interviewer's understanding of these two t
statistics, there are already thousands of known security vulnerabilities in Windows NT series operating systems. And with the introduction of the new operating system, new vulnerabilities will be found more.
Security recommendations: For our ordinary users, we should first be to fill the loophole, operating system loopholes like an illegal channel, through this channel virus can enter the user's computer at will, so to make the operating system sec
Summary: Built-in type of machine implementation, Word/byte/bit, memoryFirst, the conceptThe computer stores data in a bit sequence, with each bit not 0 or 1, such as: 00011011011100010110010000111011 ...Second, the computer to block to handle memory
The computer handles memory as a block with a power of 2 whole number of bits

I have encountered big-end and small-end problems in data storage. My sister was confused and found that my basic knowledge was seriously lacking, first, let's take a look at how many bytes each data type occupies on your own machine, and the size of these data types is related to Shenma. Various materials are checked, and then code verification is written. In this article, you can add basic knowledge to yourself.
Let's first list the Data
