What is meant by 3 MHz CPU?
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.
Are speakers input or output?
Regardless of their design, the purpose of speakers is to produce audio output that can be heard by the listener. Speakers are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver.

What is output devices of computer?
An output device is any piece of computer hardware equipment which converts information into human-readable form. It can be text, graphics, tactile, audio, and video. Some of the output devices are Visual Display Units (VDU) i.e. a Monitor, Printer, Graphic Output devices, Plotters, Speakers etc.
What are the two types of output?
Monitors and printers are two of the most commonly-known output devices used with a computer. Computer output devices are all peripheral hardware, and are connected to a computer by cables, or by wireless networking.

How many input and output devices does a computer have?
Keyboard and mouse are the most commonly used input devices. Microphone gives sound or voice input to the computer. Output devices are used to display the result or information on the computer. Monitor and the printer are the commonly used output devices.
What are the inputs on a computer?
Fortunately, computers have come a long way since the 1970s, and we can now input data into them using a variety of easy-to-use devices. The most common input devices are the keyboard, mouse, and touch screen. Portable keyboard, wireless mouse, and iPhone.
Is CPU input or output?
The CPU processes instructions, performs calculations and manages the flow of information through a computer system. The CPU communicates with input, output and storage devices to perform tasks. An output device lets a computer communicate with you.
What does the input do?
In computer science, the general meaning of input is to provide or give something to the computer, in other words, when a computer or device is receiving a command or signal from outer sources, the event is referred to as input to the device.
What is the input function?
The input function is used to ask the user of the program (not the programmer) a question, and then wait for a typed response. The typed number is then returned as the result of the function, and should usually be stored in a variable: age = input(‘how old are you: ‘);
What devices are input and output?
Input and Output DevicesKeyboard.Mouse.Microphone.Bar code reader.Graphics tablet.
What three parts of a computer can accept input?
Answer Key: How Computers Work The keyboard, mouse, and modem are input devices. The monitor, printer, and modem are output devices. The computer hard disk is for long-term storage.
What is input and output math?
In mathematics, input and output are terms that relate to functions. … You’ll also see functions in the form of one variable (often y) equal to an expression involving another variable (x). A simple example is y = x2 (which you can also write f(x) = x2). In such cases, x is the input and y is the output.
What is input and its types?
An input device is any hardware device that sends data to a computer, allowing you to interact with and control it. The picture shows a Logitech trackball mouse, which is an example of an input device. The most commonly used or primary input devices on a computer are the keyboard and mouse.
Why does CPU need to process the input?
The CPU isalso known as the processor or microprocessor. The CPU isresponsible for executing a sequence of stored instructions called a program . This program will take inputs from aninput device, process the input in some way and output the results to an output device .
What are the 3 parts of the CPU?
The CPU is made up of three main components, the control unit , the immediate access store and the arithmetic and logic unit .
