encode characters in various standards, such as ASCII and Unicode(... to stores letters and sentences. The most common technique are to encode the charactersUsing ASCII or Unicode.)ASCII codes are not affected by the size-end mode because they account for only one byte.(the endian ordering of a system does not play a role in how the characters is stored because these are separate 1-byte V Alues.)4. Data structure structure describes the layout (or I

began to review the computer Foundation in NetEase Cloud class, thank you for the opportunity of my teacher to learn!1. The social nature problem is transformed into an algorithm by symbolic and computational method, and then it becomes the result of an algorithm by calculation, and then the result of solving the problem by semantics.2. Basic elements of a high-level language3. The solution to the problem i

Computer hardware can actually be more easily divided into CPU + memory +io devices. The three of them are through a bus to exchange data, and you know in the three CPU speed of the fastest, memory second, IO device third, to make the three coordination of communication requires a certain control. 2. our CPU has its own local bus, the same memory, the local bus through the motherboard of the South Bridge chip link together to communicate.
