Single Bus Structure

 

Single Bus Structure

• Let us first know what is meaning of Bus in CS  

A bus is basically a group of lines or maybe a group of wires that is used to connect several devices. The lines in a bus carry data or address or control signals.

There are two types of Bus structures: Single Bus and Multiple Bus structure.

• Now coming to what is Single Bus Structure

It is the simplest way to connect several devices together. In a single bus structure I/O devices, memory and processor are connected to the same bus. In this bus structure, only two units actively can use a bus at a given time; it means that data can be transferred between only two devices at a given time.

Once the bus is free the device can call the bus using an interrupt signal. The transfer of data is done using registers. Registers are a type of memory that is used to store, transfer data or instructions.

• Advantages

• It is flexible.

• Cost-efficient.

• Easy to understand.

• Disadvantages

• The time taken to execute a process is slow compared to multiple bus structure.

• The number of registers is less.

• Multiple devices cannot use the bus simultaneously.
