CPU speed is the central factor in a computer's performance. And this CPU speed depends on the processor in the CPU chip. In a computer, clock speed refers to the number of pulses per second generated by an oscillator that sets the tempo for the processor. Clock speed is usually measured in Hertz (Hz).

But now-a-days, a pure processor's performance is measured in MIPS (Millions of Instructions Per Second). As here in the question, how a processor's speed is measured is asked and it is Hertz. 

Hence, Processor's speed of a computer is measured in Hertz(Hz) [MHz, GHz].

Lightning is extremely hot — a flash can heat the air around it to temperatures five times hotter than the sun’s surface. This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.

Lightning heats the surrounding air to about 30,000 degrees Centigrades.

DPI [Dots Per Inch] is a measurement of output quality of printer resolution. It represents number of ink dots the printer can place in an area of one square inch. The lesser the DPI the less sharper the image and vice versa.

Therefore, a printer that may have 400 DPI, a printer that can print 400 x 400 per square inch or 1,60,000 dots per inch.

The main parties involved in the IR system are: 

i.) Employers – They are the ones who possess the rights to hire the employees and remove them. They also possess the rights to relocate, close or merge the business. They can opt for technological changes as and when they see it in the interest of business. 

ii.) Employees – They are actually the ones who keep the business moving. They possess the rights to voice their opinions and feelings while striving for betterment. They usually form the unions to negotiate with the employers.

iii.) Government – Government is the one who influences the IR system with laws, rules, agreements, awards of court etc. They also include third parties & labour and tribunal courts to manage the IR system.
