About the buses running inside the computer

What is a bus?

A bus is a connection between computing devices, also known as an electronic partway or a group of wires.

What do these wires carry? They carry data. If we connect two hardware devices in the same path, we have communication ports. These are hardware ports. The hardware port has a serial port or a parallel port.

Carrying capacity

Bus width depends on the width of the road at one time. This width is called the width. The width of the bus is 16bit at a time.

Frequency (MHz)

Frequency is measured in Hz. The frequency bounce can be many times per second. In computers, the frequency speed is usually measured in MHz to GHz.

Transfer speed

Transfer speed is important in a computer. It calculates how fast data is being transmitted per second. The frequency is 133MHz per second. The data bit that can carry data is 16bit per second.

(1byte = 8bit)

16 * 133.106 = 2128 * 106 bit / s,

or 2128 * 106/8 = 266 * 106 bytes / s

or 266 * 106/1000 = 266 * 103 KB / s

or 259.7 * 103/1000 = 266 MB / s

At megabytes, you get 266MB / s.

Primary bus

Generally, the computer has an internal bus and an expansion bus. The internal bus is also called the front-side bus, also called the FSB bus. It operates between the processor and the memory. The expansion bus is also called the input/output bus (I / O bus). USB, serial port, parallel port, PCI connector, hard drives, CD-ROM, CD-RW Drives.

North Bridge and South Bridge bus

The North Bridge is called the memory controller and operates between the processor and memory. The bus that connects the processor, Northbridge and RAM is called the FSB bus. The northbridge bus is connected to the south bridge bus. The southbridge is the input/output controller or expansion controller. Also called the southbridge
The bus controls ISA, USB, IDE, SATA.

The PCI Express Bus

PCI stands for Peripheral Component Interconnect Express, abbreviated as PCI-E, sometimes 3GIO (3rd generation input/output).

It is a bridge between the cards that come as an expansion board on your computer. If you want to install a graphics card on your computer, a PCI-E bus is provided between these devices and the controller chip. PCI Express was launched in July 2002.
