History of processes and threads We all know that computers are made up of hardware and software. The CPU in the hardware is the core of the computer and it assumes all the tasks of the computer. Operating system is the software running on the

Threading. Thread Thread is one of the most important classes in the threading module and can be used to create threads. There are two ways to create a thread: One is to override its run method by inheriting the thread class, and the other is to

One, what is shared memoryShared memory, as the name implies, allows two unrelated processes to access the same logical memory. Shared memory is a very efficient way to share and pass data between two running processes. Memory that is shared between

Topic:An integer is stored in memory and outputs the number of 1 in the binary representation of itIdeas:To determine the number of 1 in the binary representation of this integer, it is the topic of the [bitwise operation].The first thought of

High-precision operation is an important algorithm of information science. This algorithm is calculated using multiple storage units, so it is more computationally scoped than a typical storage unit. It is also a frequently-tested topic in some

Most computers use a 8-bit block (known as Byte byte) as the smallest addressable memory unit, rather than accessing individual bits in memory. The program treats the memory as a very large byte array called the virtual memory (virtural memories).
