How is hertz related to the speed of a computer processor? What is clock speed and how is it related to the speed of a computer processor? What is a computer bus? How does a computer bus carry information? Why is bus width important? Ethics Discussion: . Dig ital devices are produced using multiple production inputs including natural resources and labor. Responsible production practices are one consideration when purchasing a new digital device. Conduct research on the Internet about the ethical production of digital devices/computer. What are some of the issues that surround the ethical production of digital devices/computers? What ethical factors would you conExplanation / Answer
Firstly, we will see what is Hertz(Hz) - Hertz is unit of frequency in International System of Unit and is defined as one cycle per second Cycle per second.
It is named for Heinrich Rudolf Hertz Heinrich Hertz , the first person to provide conclusive proof of the existence of electromagnetic waves, hence a processor is operating on its level of so much frequency with emitting electromagnetic waves in micro level this speed frequency is represented in Hertz as per the terms of physics.
That is the processor changes state how many times per second, 3GHz means 3 billion times per second.
Speed Of Computer Processor - Speed of processor is measured in clock cycle per second, and it’s SI unit is Hertz.,Hence Hertz related to the speed of a computer Processor
Clock Speed - One hertz is equivalent to one cycle. One cycle meaning one refresh, process, etc. A screen is measured in hertz-typically 60 hertz. That meants it refreshes 60 times in one second. One hertz is one refresh or cycle per second.Modern processors are typically using frequency in the GHz (billions of cycles) range.This is 4.5 billion cycles per second, or 4.5 billion 1’s or 0’s in binary, or 4.5 billion transistors switching to On or off, or some combination.
However, it's important to realize to you that a higher clock speed does not always mean faster since different processor architectures capable of different things per clock cycle, and they may even contain multiple processors (as cores) in a single unit, so you can not judge the processing performance based on the clock frequency alone.
Computer Bus - BUS is an electronic road along which signals are send from one part of the computer
According to me, think bus like a highway. The start point is city hall (CPU) the second stop is the resturant (RAM) etc, mother board has lines which are made of gold and the componets sets in the path and internally they decide where data goes. That is how simple i can make it just think of it like a little city.
A computer bus acts as a “bridge” between all components, carrying out all communications over a single data channel. It reduces the number of "pathways" needed for those communications, in turn increasing data speed and decreasing latency.Generally within a computer, there are two buses: 1.internal bus and 2.External buses , and each bus is usually built up of 50 to 100 distinct physical lines that transports the data. The internal connects the processor to the central memory (RAM), and carries data within the motherboard. and the External buses connects the various motherboard slots together (USB, hard drives, CD drives, PCIs, etc.) and carry data to peripherals and other devices attached to the motherboard. and through this computer bus carry Informations.
Interesting fact-In order to communicate, two buses must have the same width. This explains why RAM modules sometimes have to be installed in pairs.
Bus width is IMPORTANT factor -Bus width is how many bits can simultaneously go from the CPU to the other components connected to it on the system board.An 8 bit CPU would have an 8 bit bus width. A 64 bit CPU would have a 64 bit bus . Depends on whether you are asking about the data bus or the address bus.The address bus directly determines how much ram you can access and data bus determines how much data can be accessed at once.In practice,a wider data bus can improve performance in I/O intensive tasks, Having a wider bus means that the CPU can transfer more data at a time.,Hence bus width is important
