Question

What are gigahertz and cache?How does it affect the performance of the computer?If gigahertz is higher,will the computer's speed be higher?What is FSB?

Answer 1

GHz is the speed of the processor the higher the numer the faster the computer.

Cache is a bit of memory built into the processor which operates at very high speed, the bigger the faster the computer.

FSB is Front Side Bus the speed data is transfered into and out of memory, the higher the number the faster the computer.

Answer 2

Frequency is the number of cycles per unit of time. Hertz represents the number of cycles per second. prefixed to Hertz (abbreviated hz) are indications of volume - kilo (thousand), mega (million), giga (billion). so a 2 gHz (gigaHertz) machine has 2 billion cycles per second. Why is a cycle important? Because a simple computer instruction takes one cycle. A single instruction entered on a computer screen (e.g., open a browser with a double click on an icon) could take billions of computer instructions to complete (open the window frame, go to the internet and fetch the content, download the content, interpret the content and follow the instructions, etc etc etc. All else being equal, the higher the Hz, the faster the machine. A 2 gHz machine can execute twice the number of instructions as a 1 gHz machine, in the same period of time. Doesn't mean that it will, just that it can. (other variables could prevent 100% realization of the improvement)
FSB - Front Side Bus - a Bus, in the computer, is a pathway for high speed transfer of information. Depending on how the computer is built (deep hardware understanding required for technical discussion - I'm not your man for that), there may be one bus, or more. Just another part of what makes the computer work, hopefully fast enough to keep you happy.

Cache (not cash=money) is a fastest-access memory storage area built into the motherboard of the computer, used to optimize the system's performance and make it run faster without losing accuracy.

Answer 3

Gigahertz is the speed of the Central Processing Unit of your computer, sorta like the brain of the computer. The higher theGighertz the faster it is, usually. Cache is uhh forgot..sorta like storing info. FSB = Front Side Bus.

Answer 4

Hi there

This is all to do with the computer's processor. The main brain of the computer. The higher the amount of gigahertz, the better the performance will be.

Answer 5

Simple way to explain this, not totally true but the better way to picture it:

GHz is the engine of the car, bigger it is, faster it can travel.

FSB is the number of seats, imagine you have to take 4 passengers from A to B, bigger FSB (Front side Bus) meant more passengers, say each time you carry 6 passengers, your computer will need to do less journeys in order to complete the task.
