basic computer programs

Overview of the Internet 1, three network integration: telecommunications network, cable TV network, computer network.2, the Internet's two basic features: connectivity and sharing. Connectivity (connectivity): The Internet allows internet users, no matter how far apart, can be very convenient, very economical exchange of information (data, as well as various audio and video), as if these user terminals ar

computer is loaded into memory and then handed to the CPU for operation.4. Input device: Data input into the computer (mouse, keyboard, scanner, microphone, camera are input devices. ）5. Output device: Outputs the data (display, printer)6. Communication equipment: Network card (hardware necessary for Internet)Two. Software (consisting of programs and documents).

The main object of this article is CPU and memory. Why learn C language before must understand, because C language is very close to the underlying principle of the language, understand the principle of CPU and memory, to learn C language has a great help.In fact, I am a personal advocate of computer science should first learn the principles of computer composition and then learn C language, but it seems not

, approximation of nonlinear problems in numerical analysis, and so on. To solve a linear equation group, you can use the Gauss-Approximate elimination method (Gauss-jordan elimination), or Kolesky decomposition (Cholesky decomposition). 30, Strukturtensor algorithm-applied to the field of pattern recognition, to find a calculation for all pixels to see if the pixel is in the homogeneous region (homogenous region) to see if it belongs to the edge, or a vertex. 31, the merge lookup algorithm (U

Note that the following examples are just a sample, and there are many other ways to implement Basic Syntax: input and output: Normal article-input question:As a freshman, more of you may first contact programming. So the input and output as a way of interaction, naturally is very important. So the first way we learn to input and output is to cin,cout these two functions. First of all, we have the first pose: int A; cin>>a;First define

are parity bits (1/0). The sum of the number of 1 in the data and the number of the test bit 1 should be odd at parity, and the number of 1 in the data and the number of checksum digits 1 should be even when parity. When a character is received, the number of 1 is validated, and if the character is inconsistent, an error occurs during the transfer of the data. Code and checksum The sender sums the data blocks (or each byte xor), resulting in a byte of the checksum character (checksum) appended
