MHz. It's not technically called the FSB anymore though. It's called HyperTransport (for AMD) or QuickPath Interconnect (for Intel) these days.

Difference between front side bus and back side bus?

Modern processors have two bus types: the front-side bus and the back-side bus. The back-side bus is where your cache memory lives. Cache is a very small amount of very fast memory--just a couple of megabytes. It's on a separate bus because if the CPU was making cache requests along the same bus as it was making main-memory requests, it would slow the cache down so much that having it would be pointless. It's as small as it is because (1) it's expensive as hell, (2) it generates a lot of heat, and (3) nowadays, they put a lot of it in the processor itself and they don't want the processor to be the size of a Buick. The front-side bus is where your main memory lives. (This is also the bus the computer uses to talk to the video card, hard drive, modem and all the other things your computer is running, but that's not important now.) You know when you look at a computer ad, it says "This computer has 512MB RAM!" That's main memory. It's sitting on the front-side bus. And the faster that bus runs (it hasn't run at processor speed in decades) the faster your memory calls run and the faster your computer goes. Fast is good. The bus is rated in megahertz, same as your computer used to be before they started selling GHz PCs, and 800MHz is a very fast one.


Is it possible to change front side bus frequency?

Yes, it is possible to change the front side bus (FSB) frequency on some computer systems. However, this process often involves accessing the system BIOS/UEFI settings and making adjustments there. Changing the FSB frequency can impact system stability and performance, so it's important to proceed with caution and understand the implications of such adjustments.


What is the sign for object and image distances that are measured on the front side of a mirror?

Regardless of which side of the mirror you designate as the positive side, one of them is positive and the other one is negative, since the object and image are always on opposite sides of the mirror. BTW ... If the mirror is flat, then their absolute values are equal.


When you are traveling in a bus the person sitting in front of us seems to be at rest though the bus is moving?

The person in front of you appears to be at rest relative to the bus in terms of their position and speed. They are moving with the bus at the same velocity, so to you both it seems like they are at rest even though the bus is in motion. This is due to the principle of relative motion.


What is the Frequency or speed data is placed on the bus?

The speed at which data is transferred on a bus is measured in hertz (Hz), which represents the number of data transfers per second. The frequency of data being placed on the bus depends on the specific technology and protocol being used, such as 1MHz, 100MHz, or 1GHz for different types of buses.
