Explain what is meant by the term manual input device

iii) Explain what is meant by the term “ergodicity”. Is the sinusoid X(t)= Acos(wct +Q) with random phase Q uniformly distributed on [0;2p] ergodic? (There is no justification required.) [ 3 ] b) Answer the following questions about modulation and demodulation. i) Explain the terms “synchronous detection”, “envelope detection”, “co-. In this section we will look at how input devices can be used to get data into a computer system. In section we will focus on manual input devices and then move onto direct input devices in section For each input device you have to be able to identify it from an image, explain what it is used for and discuss advantages/disadvantages. Input devices are part of the four main hardware components of a computer system. The Image below shows where input dev ices fit into a computer system: There are many different kinds of input devices. They are split into two categories manual input devices and direct input devices. Manual Input devices: Data is input into the computer by hand.

Besides this, the term paddle also refers to many handheld devices designed to control a function in an electronic device, computer, etc. 12) Steering wheel: It is used as an input device in racing video games such as car racing games or in driving programs as virtual simulators to steer a vehicle. What an input device sends (inputs) to a computer depends on the device. Additionally, all input devices send data from the device over a cable or wireless transmission to the computer. For example, as you move a computer mouse, the data sent to the computer is the X-Y axis movements used to display the mouse cursor on the screen. In this section we will look at how input devices can be used to get data into a computer system. In section we will focus on manual input devices and then move onto direct input devices in section For each input device you have to be able to identify it from an image, explain what it is used for and discuss advantages/disadvantages.

Without any input devices, a computer would only be The gaming keyboards are designed for the Moves one word to the right at a time. A definition of an input device might be simply thought of as any The term human factors (HF) has several interpretations, as defined by Meister (). Input device definition, a peripheral device, as a keyboard or stylus, used to enter data into a computer for processing. See more.
