A:An MP3 player contains a number of critical components, and a single failure can cause it to stop functioning. According to Sony, The best way to test an MP3 player to see if it still works is to charge it.
A:The iPod, a digital music player, works by storing audio and video files on a hard drive. A graphical menu system allows users to access and play files. The device integrates with iTunes software on computers to back up files and purchase new media from the iTunes store online. Headphones are needed to hear audio on certain models of iPods, as of 2014.
A:A radio does not have the same advantages as other means of communication and entertainment such as the television and the Internet. It lacks visual appeal as no pictures emanate from a radio. A radio signal has limited strength.
A:A dipole antenna uses two conductors of the same length to detect radio waves and transmit the corresponding variable electrical current to a receiver. Each conductor represents one-quarter of a wavelength, and when combined, the dipole can detect a half-wavelength signal. The length of the two conductors determines the operational frequency.
A:Studying information systems helps find the most efficient way to harvest and store data so it can be easily used. Efficiency in these systems can help solve problems in areas such as logistics or automation, reducing the amount of wasted effort or confusion due to poor information management.
A:A binary code converter is a program that lets users convert binary code into simple text. Binary code is code used by computers based on the binary number system, a number system in which there are only two states, on and off, symbolized by zero and one.
A:General-purpose software refers to computer applications that are not designed for a particular business, industry or department. These applications may, therefore, be adopted and applied by many professionals, including engineers, security analysts, accountants, chemists, medical officers and attorneys.
A:The difference between megabytes and gigabytes is the number of bytes that make up each unit and the amount of data they hold. A megabyte holds a million bytes, or about 1,000 kilobytes. A gigabyte holds about a billion bytes, or around 1,000 megabytes.
A:Embedded software refers to computer programs that directly interact with hardware. These programs are typically built to perform a specific function or to make the hardware perform in a specific way, and several pieces of embedded software may be built into a single piece of hardware. Embedded software is an integral part of the hardware into which it is built.
A:A computer mouse may freeze or become unresponsive because of accumulated dirt, use of the wrong settings or a bad surface. An incompatible driver, a loose cable or interference from other input devices may also cause the computer mouse to function abnormally.
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: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: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:Though largely defined by the quality and size of the photos in question, an 8GB memory card is capable of holding up to 1,000 24-megapixel photos. Fewer pixels require less data, and thus more can be stored on a memory card.
A:Memory Stick is the brand name for a proprietary Sony-owned storage format, whereas a flash drive is a generic category storage format. Both products use flash memory in order to save data, but Sony Memory Sticks generally work exclusively with Sony devices as opposed to flash drives, which connect to any device via USB.
A:An industry standard 74-minute audio compact disk can hold 650 megabytes of data. Other industry standards are the 80-minute, 700 megabyte disks and the 21-minute, 185 megabyte disks. CDs with higher capacity, up to 890 megabytes, exist but don't conform to industry standards and may not work in all readers.
A:CDs and DVDs that have already been burned with music and other data can still accommodate more files, but only if they are configured as multi-session discs. Burning additional music to a multi-session disc requires that the disc has remaining free space.
A:A hypermedia database is a computer information retrieval system that allows a user to access and work on audio-visual recordings, text, graphics and photographs of a stored subject. The World Wide Web is a perfect example of a hypermedia database.
A:You can make a bootable USB using the Windows command line. Creating a USB boot drive varies with different operating systems, so check with the instructions for your operating system if you use something other than Microsoft Windows.
