What sends data to the CPU?

Through buses.


How does a hard disk connect to the memory and the CPU?

Via data communication channels called data buses and the motherboard.


What is Buses and what does it do?

Data bus - transfers data round system address bus - CPU provides the addresses to where the data must be fetched, through this bus control bus - timing and signals which control data flow in the system.


Does data use the CPU?

The CPU processes data, so data would be using the CPU.


Why the CPU execute faster than the input and output device?

The CPU is incredibly fast at executing data. The only problem is getting data to the CPU. This arduous task is carried out by the various buses - The control bus is a line which the CPU sends information about what device it wishes to communicate with The data bus carries the actual data The address bus carries memory locations. This means that the I/O device has to do the following: 1. Inform the CPU that it wishes to talk. (It does this via IRQ [Interrupt Request] channels) 2. The CPU will inform the device that it is ready to talk through the Control bus. 3. The device will set its' ready signal to 0, meaning that it is sending data, then it will put the data on the data bus. 4. The CPU will receive the data, storing it in registers. 5. The device, once it has finished, will set the ready line to 1. 6. The CPU will read and execute the data, performing whatever is necessary. 7. The CPU will inform the device that it has finished 8. Then, if necessary, the CPU will pass any data back along the data bus, setting the data bus ready line to 0. The main drawback is this: Only one device may use these buses at any one time. The CPU is far faster at doing the actual execution than it is to actually get all of the necessary instructions to the CPU. I hope that answered your question.


What is the need of the buses?

the purpose of buses is to reduce the number of pathways needed for communicate between the components , by carrying out all communication over a single data channel. synchronization- synchronization between components can set with help of buses. buses are used for high speed transfer between CPU, memory and other devices .


What is the name ofThe parts of a computer are connected by collections of wires?

The collections of wires that connect the various parts of a computer are called "buses." These buses allow for the transfer of data between components such as the CPU, RAM, and storage devices. Buses can vary in speed and width, with faster and wider buses allowing for faster data transfer. Some common types of buses include the front-side bus (FSB) which connects the CPU to the northbridge, and the peripheral component interconnect (PCI) bus which connects various peripheral devices to the motherboard.


What is Computer Bus Also explain that how many types of Buses used in Computer with their functions.?

Buses are the set of wires that carry special information to or from the CPU. There are three types of buses they are: 1. Address buses: these buses carry address given by the CPU from one unit to another in the computer. 2. Data buses: These buses carry data from one unit to other, it is a bi-directional bus i.e the data can be carried in both directions. 3. Control signal: These buses carry control signal from ALU to memory and from memory to alu and then to the output unit.


What are three bus types present in every CPU?

Three types of buses are, 1. Memory buses 2. Address buses 3. Input Output buses


Why Direct memory access has priority over the CPU when both request a memory transfer?

we can transfer data direct to and from memory without the need of the CPU. The transfer of data between a fast storage device such as magnetic disk and memory is often limited by the speed of the CPU. Removing the CPU from the path and letting the peripheral device manager the memory buses directly would improve the speed of transfer. This transfer technique is called direct memory access(DMA). During DMA transfer, the CPU is idle and has no control of the memory buses. A DMA controller takes over the buses to manage the transfer directly between the I/O device and memory. With Regards.

What are the different types of buses in computer?

Silly answer - They come in many varieties, both double decker and single. Some even have open roofs! More serious - There are a number of type of PC buses. Front side bus, QuickPath Interconnect (QPI), or HyperTransport bus (HT): This connects the CPU to the memory controller or northbridge chip. However, in the HT and QPI implementations, the memory controller is a part of the CPU, freeing up the bandwidth of the bus for other things. LPC bus: Used to connect the system BIOS, super I/O controller (keyboard, mouse, serial, parallel, floppy), and even a trusted platform module (TPM) to the southbridge chip. Memory bus: This connects the memory to the memory controller, northbridge chip, or CPU. Peripheral buses: These connect the motherboard to peripheral cards. This includes ISA, EISA, VLB, PCI, AGP, PCIe, etc.
