What is a system bus?

The system bus is the common channel for transmitting information between various components in the computer system. The operator, controller and register all belong to the same component of the CPU, so the options A, B and C are excluded and only D is selected.

[Answer]: (1) The system bus, also known as the front-end bus (FSB), is used to connect the CPU and RAM (including the internal cache of the CPU and the main memory of the system), which is the main trunk for the implementation of all component functions on the computer motherboard. ( 2) The basic functions of the system bus interface are as follows: 1) Control.

System bus refers to the information transmission line between the major components of cpu, main memory and I/O equipment. The system bus is divided into address bus, data bus and control bus. The data bus is used to transmit data information between functional components.

System buses are divided into the following three categories: control bus. It is mainly used to transmit control signals and timing signals. Data bus. It is a two-way three-state bus, which can not only transmit the data of the CPU to other components such as memory or input and output interfaces, but also transmit the data of other components to the CPU. Address bus.

SystemBus is a separate computer bus, which is the main component connecting the computer system. The development of this technology is to reduce costs and promote modularization.The system bus combines the functions of the data bus to carry information, the address bus decides where to send the information, and the control bus decides how to act.

What are the basic characteristics of the fieldbus control system?

1. Characteristics of the fieldbus control system: the openness, interoperability and distributed system structure of the system. The wiring of the fieldbus system is very simple. A pair of twisted pair cables can connect multiple devices. When it is necessary to add on-site control equipment, it can be connected to the original twisted pair cable nearby, which not only saves investment, but also reduces the installation workload.

2. Features of the fieldbus system: (1) The openness of the system. The fieldbus is an open Internet network, which can be interconnected with both similar networks and different types of networks.(2) Interoperability.

3. Fully digital communication (2) Open Internet network (3) Interoperability and interoperability (4) Intelligentization of on-site equipment (5) Highly distributed system structure (6) Adaptability to the on-site environment On-site control equipment has communication functions, which is convenient to form a factory base Layer control network.

4. The characteristics of fieldbus are mainly reflected in two aspects: first, it successfully realizes serial connection in architecture, which overcomes many shortcomings of parallel connection in one fell swoop. The second is to successfully solve the two major problems of open competition and equipment compatibility in terms of technology, and realize the high intelligence, interchangeability and decentralization of on-site equipment.

5. Data communication is convenient and fast. As a means of data transmission of precision control system, fieldbus has efficient and rapid data transmission speed and stability.Fieldbus can effectively reduce the error rate and communication delay in data transmission, and can transmit various types of data, control instructions and monitoring information through network connections.

What is the third-class computer system bus

The computer system bus is functionally divided into: data bus, address bus and control bus, which are used to transmit data, data address and control signal respectively.

System buses are divided into the following three categories: control bus. It is mainly used to transmit control signals and timing signals. Data bus. It is a two-way three-state bus, which can not only transmit the data of the CPU to other components such as memory or input and output interfaces, but also transmit the data of other components to the CPU.Address bus.

is the data bus DB, address bus AB and control bus CB, also collectively known as the system bus. Data bus DB" is used to transmit data information.

The third type of computer system bus is classified according to the type of information transmitted by the computer, which refers to data bus, address bus and control bus respectively. Data Bus DB" is used to transmit data information.

There are three main types of computer system buses, which are: Data Bus: Data Bus is responsible for transmitting data between CPU, memory and input/output devices. It is a wide bus that can transmit multiple data items at the same time.

What are the types of system buses and what are their functions?

The system bus is divided into: address bus, control bus and data bus according to the transmission content. Address Bus is a kind of computer bus, which is CPU or has DMA capability.Units are used to communicate the physical addresses of these units that they want to access (read/write) computer memory components/places.

Control bus: mainly used to transmit control signals and timing signals. Data bus: It is a two-way three-state bus, that is, it can not only transmit CPU data to other components such as memory or input and output interfaces, but also transmit data from other components to the CPU.

System bus is divided into address bus, data bus, and control bus. The data bus is used to transmit data information between functional components. The address bus is used to indicate the address of the live I/O device of the data source or destination data on the data bus in the main memory unit. The control bus is a transmission line used to send various control signals.

System bus can be divided into memory bus, bus and I/O bus, etc.The memory bus is used to connect memory and chipsets; the bus is used to connect chipsets and I/O devices, such as graphics cards, sound cards, network cards, etc.; I/O bus is used to connect external devices of computers, such as keyboards, mice, printers, etc.

"Data Bus DB" is used to transmit data information. The data bus is a two-way three-state bus, that is, it can transmit CPU data to other components such as memory or I/O interface, but also to transmit data from other components to the CPU.

System bus can be divided into three categories

System bus can be divided into: control bus, data bus and address bus. It is mainly used to transmit control signals and timing signals. Data bus. It is a two-way three-state form.The bus can not only transmit the data of the CPU to other components such as memory or input and output interfaces, but also the data of other components to the CPU. Address bus.

The three types of computer system buses are Data Bus DB, Address Bus and Control Bus CB. Data Bus DB is used to transmit data information.

System buses are divided into the following three categories: control bus. It is mainly used to transmit control signals and timing signals. Data bus. It is a two-way three-state bus, which can not only transmit the data of the CPU to other components such as memory or input and output interfaces, but also transmit the data of other components to the CPU.Address bus.

Control Bus CB: used to transmit the control signals of the CPU to the main memory and external devices. Such a structure makes the relationship between each component become a single-facing bus relationship.

What are the three types of computer system bus

Analysis: Computer system bus is functionally divided into: data bus, address bus and control bus, which are used to transmit data, data address and control signals respectively.

Bus is a common path for data transmission within a set of computers, which is used to realize communication between two or more components in the computer, generally including address bus (AB), data bus (DB) and control bus (CB)..

The bus of a computer is divided into: control bus, data bus and address bus. Control the bus.

is the data bus DB, address bus AB and control bus CB, also collectively known as the system bus. Data bus DB" is used to transmit data information.

The system bus of the computer has three types: Data Bus, Address Bus AB and Control Bus.

There are three main types of computer system buses, which are: Data Bus: Data Bus is responsible for transmitting data between CPU, memory and input/output devices.It is a wide bus that can transmit multiple data items at the same time.
