Hey readers! Today the topic of this blog post is computer buses and type of the computer buses. We cover all the major topics of computer buses. Its types and history of the generation of buses.

In our previous blog posts, we cover other communication components. The central processing unit, registers, and other components of the computer system. The computer buses depend on CPU, memory, and input-output.

Computer Buses

What is Bus? The bus is the arrangement in which all computer peripherals connected. So all signal passes through this network topology.

Computer buses are the source of communication between different parts of the computer. They communicate hardware and software with each other. All the communication parts of the computer use computer buses. To communicate with other parts of the computer.

The wires, use to connect hardware with a computer used as buses. But in modern terms, physical components like protocols are also used as terms for buses. So now the buses are both parallel and bit-serial connections.

The function of Buses in Computer

The function of buses in computers is to transfer data between different peripherals. For example, a protocol in the computer is a set of instructions. It can send data like addresses or data to different protocols or components.

The hardware and peripherals connected with the computer. Buses used these components to transfer data from one place to another.

The computer buses located on the motherboard. Three types of computer buses are on the motherboard. They are the data bus, address bus, and control bus. In this blog post, we read in detail about the type of computer buses.

History and Generation of Computer Buses

There are several groups and people working on bus standards. The groups include superbus, bus architecture standard, and open microsystems initiative, etc.
Now you can read the short note on three different generations of buses.

First Generation of Buses in Computer

The buses in history consist of bundles of wires. These wires attached to the memory of the computer and peripherals of the computer. The data is transfer between the components of a computer using these wires. These wires called buses. One bus is for memory and more than one buses for components of the computer.

In early computers, the input and output waiting in loops. When one process becomes an end then the next will be working. This takes a lot of time. If the second process worked after compilation of the first. Then it takes time to go back. This is the reason for the loss of data. The main complication of early computers is this.

Channel controls introduced by a high-end system. This can reduce the CPU workload. Channels control all the work of buses. Help buses to do their task. Provide better system performance.

Second Generation of Buses in Computer

The second generation buses divide the computer into two parts. One is CPU or memory and the other consists of some peripherals. Buses transfer data from one side to another.

The size of buses increased from 8-bit to 16-bit or 32-bit. Bus controllers work in that sense. They transfer data from the CPU to other computer components. So the burden of CPU reduced.

The speed of CPU and memory increased. But the speed of buses is reduce. This problem solved after when the external devices introduce.

New Era in Generation of Buses

A new era of buses is also the third generation of buses in computer. This era of modern buses starts in 2011. In their physical connections, these buses are very flexible. Both internal and external buses connected and work at a time. This can overload the system. Modern buses reduce this complexity.

Type of Computer Buses

Type of computer buses classified as internal or external computer buses. It also includes the data bus, address bus, and control bus. As you read these three types in components of the computer.

Here you can read all internal or external and other types of computer buses.

Internal Bus

The internal buses work inside the computer. This type of computer bus connects the internal parts of the computer. For example, connect CPU and memory. Buses connect these peripherals with motherboards.

External Buses

External buses work outside the computer. All types of hardware components of computers connect with these types of buses. For example, the external buses connect the printer with the computer.

Address Bus

The address bus used to save the address of data. The size of the address bus depends on the data of memory. The address saves in the address bus is the physical address of the computer. It carries the location of data in memory.

Memory or Data Bus

The memory bus connects the main memory with the memory controller. Data bus used to transfer data.

Data saved in the address bus. The data bus sees that data location and transfers this data to the other part of the computer.

Expansion Bus

To see the better quality of videos or games we use graphics cards. These cards inserted into the motherboard. The expansion cards installed on the slots. The slots located on the motherboard. The expansion bus connects the expansion slots. Speed of buses measured in MHz’s.

Wrap Up the Post

Here is the complete detailed blog post on computer buses and type of the computer buses. Now we have a clear concept of how buses work and the place where buses located.

The detail of type of the computer buses also complete. Function and generation history of computer buses detail also included. The complete guide on computer buses is here. If you like this, then please share it with your friends.
