What is the bus speed of a 1.86 GZ computer?

Answer 1

It can vary, please list the brand of processor.

Answer 2

A bus is simply a circuit that connects one part of the motherboard to another. The more data a bus can handle at one time, the faster it allows information to travel. The speed of the bus, measured in megahertz (MHz) or gigahertz (GHz), refers to how much data can move across the bus. The more important bus is the Front Side Bus (FSB), which is the main path from the processor to the rest of the motherboard, it is also known as CPU bus speed, external CPU speed, memory bus and system bus. The FSB connects the computer's processor to the system memory (RAM) and other components on the motherboard. These components include the system chipset, AGP card, PCI devices, and other peripherals. In general, a faster FSB means higher processing speeds and a faster computer.
The speed of the FSB is measured in MHz or GHz, just like the processor. Most computers' processors run faster than their system buses, so the FSB speed is typically a ratio of the processor speed. For example, a Pentium 4 processor that runs at 2.4 GHz may have an FSB speed of only 400 MHz. The CPU to FSB ratio would be 6:1. A Power Mac G5, however, with a 2.0 GHz processor, has a 1.0 GHz frontside bus. Therefore, its CPU to FSB ratio is 2:1. The smaller the ratio, the more efficiently the processor can work. So if you are looking for a fast computer, don't just check the processor speed, but find out what the frontside bus speed is as well.
FSB speeds can be of 66, 100, 133, 166, 266 MHZ in older computers, and going to 400, 533, 800 MHZ on newer, fast computers (and FSB speed is increasing as more performant motherboard and CPU models are being released). The FSB speed is always configured through the motherboard, your should also consult the documentation coming with your CPU. In most cases the FSB speed is also printed on the CPU itself.

Answer 3

The 'Bus Speed' is the frequency a Pentium, Pentium Pro, or compatible is tacted with externally. The Bus Speed actually depends on :-

a) the Chipset on the Systemboard
b) the RAM on the Systemboard
c) the Second Level Cache.

So unless and until all this is known specifically it is simply not easy to answer your question.

Answer 4

We would need to know which processor you are talking about, although judging by that number I would guess it has a 533MHz front side bus, which means the actual bus speed is 133MHz. That is just an educated guess though, I would have to know the exact processor to be sure.
