Remote controlled toys are typically controlled by a transmitter, which sends a signal over a frequency to the receiver that sits in the toy being controlled. The transmitter has a power source, usually a battery, which powers the transmitter.
A:The function of an input device is to provide data and control signals to an information processing system like a computer. There are several different kinds of input devices used in a computer. These include a keyboard, mouse, scanner, microphone, joy stick and bar code reader, among others.

A:A mainframe is a large, powerful computer that can process requests from millions of users at the same time, whereas a microcomputer is a small computer designed to be used by one person at a time. Large organizations such as banks and government agencies use mainframe computers. Single users work with microcomputers to perform personal and work-related tasks.
A:A device driver is a component that a computer’s operating system uses to interact with a hardware device, such as a network adapter or modem. A driver interacts with the device through a communications subsystem to which the hardware connects. The operating system or other computer program calls a function in the driver to execute commands on the device.
A:Examples of computer hardware include a keyboard, mouse and monitor. Computer hardware is any physical equipment that is used to make up your computer. All of the individual equipment inside of a computer is also hardware, including the hard disk, motherboard, memory and any disk drives.
A:Before data is processed by a computer, it has to be fed into the computer using a keyboard, mouse or another input device. The central processing unit (CPU) analyzes the raw data and processes it into sensible information. The CPU receives instructions from the user and issues prompts accordingly. After the data is processed, it is translated to output formats that are easily understandable by the user.
A:Advantages of using computers in education include increased access to information on the Internet and enhanced classroom experiences through the incorporation of visual media. Some disadvantages include the additional cost of purchasing computers, high infrastructure costs such as electricity, and exposure to negative or inappropriate information on social sites.
A:Input, process, output (IPO), is described as putting information into the system, doing something with the information and then displaying the results. IPO is a computer model that all processes in a computer must follow.
A:If everything on a computer screen has turned sideways, the culprit is likely to be someone attempting to pull a prank; a quick combination of keystrokes changes the orientation of a computer's screen. It is startling and disorienting to see the screen display turned sideways, but it does not mean that something terrible or irreparable has happened to the computer.
A:Backing storage refers to any computer storage media besides the internal memory. When a computer restarts or loses power, it clears the internal memory. Backing storage retains data for an indefinite period even without power. Common backing storage devices include internal hard drives, external hard drives, USB flash drives, network drives, DVDs, CDs and magnetic tape.
A:The main functions of a computer are to receive, manipulate, display and store data. These basic functions are performed by commands that the computer receives either by a program or a human user. The commands that the computer receives are known as raw data. After the raw data is processed by the computer, the data that the computer displays is known as information.
A:A motherboard provides the connection between all other computer parts. Processors are attached directly to the motherboard, and the RAM, peripherals and storage devices are attached as well. Motherboards themselves, however, perform no computation and do not store information.
A:For a laptop using the Windows operating system, enter the control panel, click on the Regional and Language Options button, and proceed to change the language under the Keyboards and Languages tab. The selection changes the display language. Change your input language on the language bar to complete the process.
A:A microprocessor is a tiny electronic chip found inside a computer's central processing unit and other electronic devices. Its basic function is to take input, process it and then provide appropriate output.
A:Examples of mainframe computers as of 2014 include the IBM zSeries, System z9 and System z10 servers. IBM dominates the mainframe market as of 2014, with more than 90 percent market share. In addition to IBM machines, mainframes in use in 2014 include the ClearPath Libra brand and the ClearPath Dorado from Unisys.
A:People are surrounded by examples of modern technology every day, from cellphones to the diagnostic equipment physicians use when patients visit their offices and the software children use both in the classroom and for their homework. Modern technology constantly changes, and for the technology lover, there's always something new to discover.
A:Regarding the affects computers have had on society, there is evidence of positive effects such as instant availability of information and access to business services, and negative effects such as increased criminal activity and information dependence. Computers and technology have become a standard component in the lives of most people today and present a variety of benefits and challenges.
A:For a wired or wireless mouse, unplug the USB cable, or plug and reconnect it to correct the problem. Unfreeze a laptop mouse by enabling the touchpad. To do this, you will use the Fn key and the Touchpad key.
