A:There are several different types of CD cases. The standard single CD jewel case usually measures 5.59 inches by 4.92 inches by 0.39 inches. Slimline cases usually measure 5.59 inches by 4.92 inches by 0.2 inches.
A:The standard dimensions of a CD case are 5.59 inches long by 4.92 inches wide and 0.39 inch deep. Inasmuch as some CD cases are designed to hold more than one CD, the case depth varies. On the other hand, the length and width of cases rarely vary.
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: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:A singer wears earpieces so he can control what he hears. A crowd or band can create background noise, which makes it hard for a singer to hear himself and the accompanying instruments or music track.
A:Digital data refers to information stored as zeros and ones, while analog data refers to other storage methods. While digital data has largely supplanted analog data, some prefer analog storage techniques. Many analog records have been replaced by digital storage.
A:Data compression is needed because it allows the data to be stored in an area without taking up an unnecessary amount of space. Data compression uses a series of algorithms to reduce the amount of real space that the data would normally take up.
A:According to Dictionary.com, computer technology is the activity of designing, constructing, and programming computers. Computer technology directly correlates with information technology. Computer technology encompasses a developing list of different software programs and devices. Computer technology is also a very popular degree program offered by many colleges; this degree program tends to focus on learning current operating systems, hardware/software training and computer repair.
A:The process of typing a subscript on a Mac differs depending on the application. Since Microsoft Word is the most widely used word processing application, the process is described for that application. To type a subscript into Word, press the Command button and the "=" keys on your keyboard simultaneously.
A:There are many advantages and disadvantages of HTML, including compatibility and difficulty of use. All Web browsers can read HTML files and webpages, but the language can be difficult to decipher, especially since one small typo could lead to a nonfunctioning webpage.
A:CSS stands for cascading style sheets, a style language used to add fonts, spacing, color and other stylistic elements to documents on the Internet. CSS is used to style documents written in markup languages such as HTML, XHTML and XML.
A:Examples of computer hardware include central processing units, motherboards, random access memory, video cards, power supplies, hard drives, optical drives, keyboards, monitors, mice and speakers. Computer hardware is all the physical components of a computer as opposed to the digital components, such as software.
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 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: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: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:Microprocessors are used in servers, desktop computers, laptops and mobile devices. They are popular in embedded devices, which traditionally use microcontrollers. Microprocessors were named to set them apart from larger processors used in the middle of the 20th century.
A:There are two main functionality differences between RAM and flash memory: RAM is volatile and flash memory is non-volatile, and RAM is much faster than flash memory. RAM stands for Random Access Memory.
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:An optical disc drive, or simply optical drive, is a piece of computer hardware that alters data on optical discs using lasers. Optical drives edit, delete and add content to CDs, DVDs and Blu-ray discs in computers and entertainment electronics. Optical drives are useless without optical discs, which typically are round, lightweight pieces of hardware with small grooves on the shiny side of the disc.
A:A hard disk's actuator is the electronic device that moves the actuator arm across the hard disk's platter, and it works hand in hand with other components to locate, write, read or delete information. The actuator assembly operates similarly to how a record player plays a vinyl record.
A:Databases provide an efficient way to store, retrieve and analyze data. While system files can function similarly to databases, they are far less efficient. Databases are especially important for business and research.
A:RAM, short for random access memory, is used by computers to store data that is being used currently or was recently used. Accessing data stored in RAM is much quicker than directly accessing data stored on the hard drive, allowing a computer to run much faster.
