Types of computer viruses The traditional computer virus classification is according to the infection pattern to differentiate, the following is the various types introduction: · Boot type Michelangelo virus, latent for a year, "hard" is to get (this did not read) · File type (1) Very standing type Datacrime II D

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 Bytes: The smallest add
