A:Fifty decibels is the level of noise of a quiet conversation at home or a quiet stream. In comparison, the general base of 70 decibels is the noise level of a vacuum cleaner or of radio and TV audio.
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 Many analog records have been replaced by digital storage.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:According to the University of Southern California, radios work by encoding information on radio waves then broadcasting the radio wave with the encoded information onto a particular frequency. Both AM and FM radios use radio waves to transmit programs on radio stations.
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: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: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: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: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: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: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:Enable a wireless connection by pushing a hardware button on the device and then activating the computer's wireless software on Microsoft Windows laptops. After the wireless hardware is ready, select a wireless connection from the menu of choices.
A:An optical cable is used to transfer signals using light through thin, flexible glass fibers known as optical fibers. This method of data transmission is extremely fast because light travels faster than anything else in the known universe.
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 computer-controlled telescope is a regular telescope that has been mounted to a motorized platform. This platform gradually moves through the observation period to compensate for the apparent motion of the sky. The exact path the telescope follows has to be programmed into the controlling computer.
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: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.
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.
