- MHz is a speed, and it means the number of cycles per second, ns means nanosecond, an actual period of time. A nanosecond is one billionth of a second. 100MHz means there are 100 million clock cycles per second. That means one tenth of a clock cycle per nanosecond, or one clock cycle in 10ns.

- The SI unit of speed is the metre per second (m/s). In dry air at 20 °C, the speed of sound is 343.2 metres per second (1,126 ft/s). This is 1,236 kilometres per hour (768 mph; 667 kn), or a kilometre in 2.914 s or a mile in 4.689 s.

Central processing unit A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.he term has been used in the computer industry at least since the early 1960s. Traditionally, the term CPU refers to a processor, more specifically to its processing unit and control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry.

Microprocessor One common measurement for a microprocessor is the clock speed, which is the speed at which the microprocessor executes instructions measured in Hertz (Hz). A computer running at 3.2 GHz (or gigahertz) can execute 3.2 billion instructions per second.

Clock Speed Clock speed is the rate at which a processor can complete a processing cycle. It is typically measured in megahertz or gigahertz. One megahertz is equal to one million cycles per second, while one gigahertz equals one billion cycles per second. This means a 1.8 GHz processor has twice the clock speed of a 900 MHz processor.

How Do You Calculate Processor Speed on Multi-core Processors? Each core is in fact doing x calculations per second, thus the total number of calculations is x(cores). Clock speed is rather a count of the number of cycles the processor goes through in the space of a second, so as long as all cores are running at the same speed, the speed of each clock cycle stays the same no matter how many cores exist. In other words, Hz = (core1Hz+core2Hz+…)/cores.

BogoMips BogoMips (from bogus and MIPS) is an unscientific measurement of CPU speed made by the Linux kernel when it boots to calibrate an internal busy-loop. An oft-quoted definition of the term is the number of million times per second a processor can do absolutely nothing.

Jan's Computer Basics: (Only one action can take place between pulses.). Measured in megahertz (MHz) where 1 MHz = 1 million cycles per second or gigahertz (GHz) where 1 GHz = 1 billion cycles per second. This is what they are talking about if they say a computer is a 2.4 GHz machine. It's clock rate is 2.4 billion cycles per second.

Why You Canât Use CPU Clock Speed to Compare Computer Performance Why You Can’t Just Compare Clock Speeds. CPU clock speed, or clock rate, is measured in Hertz — generally in gigahertz, or GHz. A CPU’s clock speed rate is a measure of how many clock cycles a CPU can perform per second. For example, a CPU with a clock rate of 1.8 GHz can perform 1,800,000,000 clock cycles per second. This seems simple on its face.

What is memory MHz? The speed of the clock is measured in Megahertz (MHz). Well, the frequency is essentially how fast something processes in a computer. In this case(memory), it determines how fast information is going to go to your memory and back. DDR, DDR2, DDR3 memories follow the DDRxxx/PCyyyy classification.

- The FSB is the interface between the processor and the system memory. As such, the FSB speed limits the rate at which data can get to the CPU, which in turn limits the rate at which the CPU can process that data. The CPU's FSB speed determines the maximum speed at which it can transfer data to the rest of the system.

Vascular Dementia As with Alzheimer's disease, advancing age is a major risk factor for vascular cognitive impairment or dementia. Additional risk factors are the same ones that raise risk for heart problems, stroke and other diseases that affect blood vessels. Many of these vascular factors also raise risk for Alzheimer's.

MHz One MHz represents one million cycles per second. The speed of microprocessors, called the clock speed, is measured in megahertz. For example, a microprocessor that runs at 200 MHz executes 200 million cycles per second. Each computer instruction requires a fixed number of cycles, so the clock speed determines how many instructions per second the microprocessor can execute.
