Is phone a machine?
Machine – an apparatus using or applying mechanical power and having several parts, each with a definite function and together performing a particular task. While a mobile phone may have mechanical parts; such as the haptic feedback or vibrating motors; they aren’t necessary for the basic function of the phone.
How does your mobile phone work?
Cell phones use radio waves to communicate. Radio waves transport digitized voice or data in the form of oscillating electric and magnetic fields, called the electromagnetic field (EMF). The rate of oscillation is called frequency. Radio waves carry the information and travel in air at the speed of light.
What are the types of device?
Types of devices
- Input devices, which write data to a computer, includes keyboards, mice, touchpads, joysticks, scanners, microphones, barcode scanners, and webcams.
- Output devices, which accept data from a computer, includes display monitors, printers, speakers, headphones, and projectors.
What classification of computer is a cell phone?
A mobile device (or handheld computer) is a computer small enough to hold and operate in the hand. Typically, any handheld computer device will have an LCD or OLED flatscreen interface, providing a touchscreen interface with digital buttons and keyboard or physical buttons along with a physical keyboard.
How do you know what band your phone is using?
For the Android phone, it could use the app: LTE Discovery, tap SIGNALS, check EARFCN(band number), ‘DL Freq and UL Freq’.

What is the use of device?
A device is a unit of physical hardware or equipment that provides one or more computing functions within a computer system. It can provide input to the computer, accept output or both. A device can be any electronic element with some computing ability that supports the installation of firmware or third-party software.
What is a device made up of more than one simple machine?
A compound machine is any device that is made up of more than one simple machine. How can a wedge be used in a system such as a complex machine? In fact, just about any type of complex machine that is used to cut objects or force things apart involves a wedge.
What is a machine designed to do?
A machine (or mechanical device) is a mechanical structure that uses power to apply forces and control movement to perform an intended action. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms…
What is device that combines two or more simple machines?
A compound machine is a device that combines two or more simple machines. For example, a wheelbarrow combines the use of a wheel and axle with a lever. Using the six basic simple machines, all sorts of compound machines can be made.
What is a simple mechanical device?
A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force.
