What is responsible for computer computing?

The most important features of an electronic computer are: stored programs and automatic control.

The operating system of a computer is: operating system (OS), which is the system software responsible for supporting the application running environment and the user operating environment in the electronic computer system, and is also the core and cornerstone of the computer system. Its responsibilities often include direct oversight of hardware, management of various computing resources (e.g., memory, processor time, etc.), and provision of application-oriented services such as job management.

Typing is not easy, such as satisfaction, hope.

It should be a network engineer.

The device responsible for the computing speed on the computer motherboard is the ** processor.

**The processor is the heart of the computer, composed of a combinator and a controller, and the internal structure is divided into a controller, a combinator and a memory, which are coordinated with each other to judge, calculate and control the coordination of all parts of the computer.

The current popular processor is the Intel Core processor, which is divided into dual-core, quad-core and octa-core. A dual-core** processor is a processor based on a single semiconductor that has two processor cores with the same function.

The index to measure the ** processor is the word length, the word length is the number of bits of binary data that the computer can directly process, marking the ability of the computer to process data, the word length determines the ability and accuracy of the computer to calculate, the longer the word length, the stronger the computer's computing power, the higher the accuracy, the more effective data storage units, the stronger the ability to find the address. Nowadays, personal computers have 16 bits, 32 bits and 64 bits in word length.

The memory that can exchange data at high speeds is called a cache, also known as a cache. The processor typically reads data from the cache and calls data to memory when the processor has no data. The larger the cache capacity, the better the processor's performance.

**The processor's cache is divided into L1 and L2 caches. In Core processors, the memory controller and cache of the four cores are all on a single chip.

CPU processor. The two major processor brands on the PC side are Inter and AMD

The arithmetic unit is the part of the computer that performs various arithmetic and logical operations. Combinators consist of arithmetic logic units (ALUs), accumulators, state registers, general register groups, and so on. The basic functions of the arithmetic logic operation unit (ALU) are the four operations of addition, subtraction, multiplication, and division, the logical operations such as and, or, non, and XOR, as well as the operations of shifting and complementing.

When the computer is running, the operation of the combinator and the kind of operation are determined by the controller. The combinator processes data from memory; The processed result data is usually sent back to memory or temporarily stored in a combinator. Together with the Control Unit, it forms the core part of the CPU.

A: The hard drive is used to store information and is an external device.

b: Combinators are used for arithmetic and logical operations.

D: RAM is the memory of the machine, to put it bluntly, it is a memory module, which is mainly used to store temporary data.

So the answer is b

CPU is the first processor, English is the core accessory in the computer, only the size of a matchbox, dozens of pieces of paper as thick, but it is the computing core and control core of a computer. The CPU is responsible for reading the instructions, decoding the instructions, and executing the core components of the instructions. Structure of the CPU:

Binary and logical operations (compare sizes such as:

0 1 returns true 1 0 returns false).

BinaryIn the 18th century, Leibniz, a master of German mathematical philosophy, read the composition structure of Bagua from the Latin translation of the I Ching sent to him by his missionary friend Bowert, and was surprised to find that its basic prime number (0) (1), that is, the yin and yang lines of the I Ching, its carry system is binary, and he believes that this is the most advanced mathematical base system in the world.

In the 20th century, which is known as one of the important symbols of the third scientific and technological revolution, the invention and application of computers, the mode of operation is binary. It not only proves that Leibniz's principle is correct, but also proves that I Ching mathematics is remarkable.

Binary numbers. One, binary number notation.

Binary is a system of numbers that is widely used in computing technology. Binary numbers are numbers represented by two numbers, 0 and 1. Its base is 2, the carry rule is "every two into one", and the borrowing rule is "borrow one as two".

Binary numbers are also based on position notation, and their bit weights are based on 2 powers. For example, a binary number whose weights are in the order of -2. For integers with n digits, binary numbers with m decimal places are expressed by a weighted coefficient formula, which can be written as:

n）2＝an-1×2n-1+an-2×2n-2+……a1×21+a0×20+a-1×2-1+a-2×2-2

…+a-m×2-m＝

where aj denotes the coefficient of the j-th position, which is a number between 0 and 1.

Binary numbers can generally be written as: (an-1an-2....

Example 1102] Write the binary number in the form of a weighted coefficient.

Solution: (2. Addition and multiplication of binary numbers.

The basic rules of arithmetic operations on binary numbers are very similar to those for decimal numbers. The most commonly used are addition and multiplication.

1.Binary addition.

There are four cases: 0+0 0

1+1 0 is rounded to 1

Example 1103] Find the sum of (1101)2+(1011)2.

Solution: 1 1 0 1

2.Binary multiplication.

There are four cases: 0+0 0

Example 1104] Find the product of (1110)2 times (101)2.

Solution: 1 1 1 0

The basic principle of a computer is to store programs and program control. The sequence of instructions (called programs) and raw data that command the computer to operate are delivered to the computer's memory memory through input devices in advance. Each instruction clearly specifies the address from which the computer takes the number, what operation it takes, and what address it sends to.

Constituent. Software systems.

Software systems include: operating systems, application software, etc. Application software in the computer industry management software, IT computer industry development essential tools, computer industry ERP software.

Hardware system. The hardware system includes: chassis (power supply, hard disk, disk, memory, motherboard, CPU ** processor, CPU fan, optical drive, sound card, network card, graphics card), monitor, UPS (uninterruptible power supply ** system), keyboard, mouse, etc. (can also be equipped with headphones, microphones, speakers, printers, cameras, etc.). The motherboard of home computers generally has an onboard sound card and a network card.

Some motherboards are equipped with integrated graphics.

How does the computer work:

1. Adopt binary.

The form represents data and instructions.

2. The program (data and instruction sequence) is stored in the main memory (program storage) in advance, so that the computer can automatically take out the instructions from the memory at high speed and execute them (program control) when working.

3. Go on and on. Until a stop command is encountered.

The basic working principle of a computer is to store programs and program control.

Computer hardware is a collection of functional components that make up a computer system. It is a general term for various computer components and equipment composed of electronic, mechanical and optoelectronic components, and is the material basis for computers to complete various tasks. Computer hardware is a physical entity that can be seen, touched, and actually exists.

Computer software refers to the collection of various programs related to the operation of a computer system and any documents and data related to them. A program is a sequence of statements and instructions that are suitable for computer execution described in programming language.

Software direction: a data storage device composed of various permutations and combinations of binary **.

Hardware Direction: An operational machine with the operation of the hardware of each part of the current belt.

The modern computer is an automatic information processing device, and the reason why it can realize automatic information processing is due to the use of the working principle of "stored program". This principle was proposed and demonstrated in 1946 by von Neumann and his colleagues in a paper entitled "A Preliminary Discussion on the Logical Design of Electronic Computers". This principle establishes the basic composition and working mode of modern computers.

Computer hardware consists of five basic components: combinators, controllers, memory, input devices, and output devices.

Inside the computer, binary is used to represent programs and data.

In the "stored program" method, programs and data are placed in the same memory (internal memory), and the computer automatically takes instructions out of the memory at high speed and executes them.

It can be said that each of the five major components of computer hardware has a relatively independent function and completes its own different work. As shown in the figure, the five components actually work in harmony under the control of the controller. First, the program that represents the calculation step and the raw data required in the calculation are sent to the computer's memory storage through the input device under the control of the controller input command.

Secondly, when the calculation starts, the program instructions are sent to the controller one by one under the effect of taking instructions. The controller decodes the instructions, and issues storage, number retrieval and operation commands to the memory and combinator according to the operation requirements of the instructions, and the results are stored in the memory after the combinator calculation. Under the action of the controller's number and output commands, the calculation result is output through the output device.

Assembly language is converted into a computer-recognized language and then output!

It introduces the hardware and functions of the computer, and focuses on the working principle of the computer, so that you can understand it at a glance and listen to it.

CPU is the abbreviation of Central Processing Unit, which can be abbreviated as a microprocessor, but it is often referred to as a processor. Don't ignore its role because of these abbreviations, the CPU is the heart of the computer, and its importance is like the brain to people, because it is responsible for processing and computing all the data inside the computer, while the motherboard chipset is more like the heart, which controls the exchange of data. The type of CPU determines the operating system and the corresponding software you use.

The CPU is mainly composed of combinators, controllers, register banks and internal buses, etc., which is the core of the PC, and is equipped with memory, input and output interfaces and system buses to form a complete PC.

Registers are important data storage resources inside the CPU, and they are one of the hardware resources that can be directly used by assemblers. Since registers can be accessed faster than memory, it is important to make the most of the registers' storage capabilities when writing programs in assembly language.

Registers are generally used to store the intermediate results of a program, and to quickly provide operands for subsequent instructions, thus avoiding the need to store intermediate results in memory and then read them in memory. In high-level languages (e.g., C C++), there are also variables that are defined as register types, which is a possible way to improve register utilization.

Computer computing is often understood as a computing scheme that meets the computing needs of a user. A specific computer application always has to use a certain computing scheme, in other words, a computer application always has to be implemented in a certain computing mode. Advances in computer technology will also lead to the emergence of new computing models.

There are many factors related to the computing power of computers, and it is a stage where computers have been constantly breaking through and developing.
