This helps your computer complete more tasks by getting them done faster. Clock speeds are measured in gigahertz (GHz), with a higher number equating to higher clock speed.
What is bus speed in computer?
A bus is simply a circuit that connects one part of the motherboard to another. The more data a bus can handle at a time, the faster it allows information to travel. The speed of the bus, measured in megahertz (MHz), refers to how much data can travel across the bus simultaneously.
What affects computer speed the most?
Memory affects computer speed because the CPU must move information into memory and retrieve data from it when running applications. If you have a lot of memory, the CPU can move larger chunks of it faster. Computers also use your hard drive as a virtual memory area when your RAM cannot hold any more data.
What makes a bus High performance?
What makes a bus high performance is the combination of latency, bandwidth, implementation and application of the instrument. These factors will impact whether an instrument bus exceeds required performance. Use benchmarks to compare actual performance between potential instruments.
What does increasing bus width do?
Increasing the bus speed adds more down beats (or "hooks", in our analogy) per second to the bus. More down beats per second means more opportunities per second for sending out code and data. Thus doubling a bus's clock speed also doubles its theoretical peak bandwidth.
What is high performance bus?

How fast is a FSB bus?
FSB speeds can range from 66 MHz to over 800 MHz. Since the CPU reaches the memory controller though the northbridge, FSB speed can dramatically affect a computer's performance. Advertisement. Here are some of the other busses found on a motherboard:
What is the back side bus?
The back side bus connects the CPU with the level 2 (L2) cache, also known as secondary or external cache. The processor determines the speed of the back side bus. The memory bus connects the northbridge to the memory. The IDE or ATA bus connects the southbridge to the disk drives.
What is the speed of the AGP bus?
The AGP bus connects the video card to the memory and the CPU. The speed of the AGP bus is usually 66 MHz. The PCI bus connects PCI slots to the southbridge. On most systems, the speed of the PCI bus is 33 MHz.
Which is faster, PCI or PCI Express?
Also compatible with PCI is PCI Express, which is much faster than PCI but is still compatible with current software and operating systems. PCI Express is likely to replace both PCI and AGP busses. The faster a computer's bus speed, the faster it will operate -- to a point.
How does clock speed affect computer performance?
Clock speeds affects that performance of a computer system by: if the frequency of the clock period is higher, then the speed of the processes within the computer will also speed up. What happens when you increase the width of the address bus?
How much data can a 256 bit GPU access?
In theory, a 256-bit GPU can access 4x as much data as a 64-bit CPU in a single LOAD operation (hence, why CPU's tend to be clocked higher, to allow for more LOAD operations to compensate for a small data bus).

Why do I need multiple CPU cores?
CPUs with multiple cores have more power to run multiple programs at the same time. However, doubling the number of cores will not simply double a computer's speed. CPU cores have to communicate with each other through channels and this uses up some of the extra speed.
What is the clock speed of a CPU?
The clock speed - also known as clock rate - indicates how fast the CPU can run. This is measured in megahertz (MHz) or gigahertz (gHz) and corresponds with how many instruction cycles the CPU can deal with in a second. A 2 gHz CPU performs two billion cycles a second. A faster CPU uses more energy and creates more heat.
What is a CPU?
A CPU can contain one or more processing units. Each unit is called a core . A core contains an ALU, control unit and registers. It is common for computers to have two (dual), four (quad) or even more cores. CPUs with multiple cores have more power to run multiple programs at the same time.
