"Power save" mode in electronics is a way to conserve energy or battery life when the item is left on but not in use. In the context of a monitor, this means the display is temporarily turned off until a user presses a key or moves the mouse.
A:Convert keystrokes per hour to words per minute by dividing keystrokes per hour by 250. According to Coleman Data Solutions, the approximate ratio between keystrokes per hour and words per minute, or WPM, is 250 to 1.
A: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: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 modern keyboard is not arranged in alphabetical order because millions of users have already learned the QWERTY keyboard layout, which is named after the first six letters in the top row of keys. The reason behind the development of the QWERTY layout as opposed to an alphabetical layout is debated, but two primary theories are accepted explanations.
A:The purpose of a computer monitor is to display text and graphics produced by computer programs and to provide a visual interface for computer users. Monitors look like television sets and attach to the main computer unit through a cable.
A:The motherboard of a computer is typically located in the bottom of the computer housing. The motherboard is a piece of plastic or fiberglass that holds various circuits, switches and electronic components. Among other functions, the motherboard allocates memory and processor capacity to various functions of the computer. It also connects to various hardware, such as sound cards and network cards, to allow them to communicate.
A:A computer database is a huge compilation of electronic files stored at a single location that is designed and modeled to support processes that require storage and retrieval of relevant information without a lot of work to the user. Computer databases are generally run and managed by specially designed applications known as database management systems software. These management systems allow users to add, edit, manipulate and store data as needed.
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:The different types of media can be broken down into two categories: print and broadcast. The Internet is also emerging as a type of media, as more and more people are getting their news from the Internet.
A:English mathematician Charles Babbage is often referred to as the "father of computing." Babbage invented the first automatic calculator, which is still regarded as a prominent example of precision engineering, in the 1800s.
A:A word processor is a software application that creates, stores and prints documents. Word processors are categorized as application software created to accomplish specific tasks as needed by the user.
A:To remove a hard drive from a tower computer, users need to back up their data, open the computer case, locate the hard drive, disconnect it by removing the IDE ribbon cable and the power computer and take the drive out. Users should make sure the computer is turned off, while performing the removal.
A:The Electrical Numerator Integrator and Calculator (ENIAC) was the first computer, and it was developed in 1946 by John Presper Eckert and John Mauchly. The duo's research was sponsored by the U.S. military.
A:A computer's processor is the control center for the computer, and it carries out the computations that allow the computer to function. The circuits in this central processing unit (or CPU) send commands to the other components of the computer to run programs, accept input and produce output.
A:The solution depends on the computer's operating system. For example, on a Windows 8 touchscreen laptop, swipe from the right edge of the screen, click Settings, select Power, and then choose Restart. In Windows 7, click the Start button, then the arrow next to Shut Down, and then Restart.
A:CNET explains that Macintosh OS X Mountain Lion was a minor upgrade to the Lion operating system. It improved applications and provided useful new features for file sharing and social connectivity. Apple computer’s Mountain Lion was the ninth major operating system released for Macintosh computers.
A:The types of robots used on Earth include Cartesian robots, cylindrical, spherical/polar robots, articulated robots and parallel robots. Each robot has a different function, but, typically, they perform the tasks that are too dangerous or boring for people.
