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: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:Getting better reception for an FM radio involves turning off other electronic devices that interfere with the radio's single, placing the radio in an area where it gets good reception or using the radio's antenna to its full potential. If the radio lacks an antenna, one is easily made using a piece of wire, such as a coat hanger.
A:The difference between analog and digital signals is that an analog signal is a continuous electrical message while digital is a series of values that represent information. Analog is conveyed by electrical current variations. Digital signals are relayed as a series of values that a device can read, such as a digital television.
A:The key advantage of a wireless microphone is that it gives greater freedom of movement. A notable disadvantage of a wireless microphone is that its operation time is limited by battery life. Compared to an ordinary condenser microphone, a wireless microphone runs on batteries that are greatly drained by the transmitting circuitry.
A:According to CodeConquest.com, server side programming is a type of programming that relies on code operated from the server of a website, not the computer that is actually accessing it. This is a sharp contrast to client side programming, where the code itself is read and interpreted by the computer accessing the code and then utilized. In server side programming, the server performs most of these script-interpreting functions.
A:A computer language translator is a program that translates a set of code written in one programming language into a functional equivalent of the code in another programming language. The different types of computer translators are interpreters, source-to-source compilers, standard compilers, decompilers, assemblers and disassemblers.
A:According to Dictionary.com, computer technology is the activity of designing and 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 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: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 modem is an external or internal device thats function is to transmit digital data over communication lines. Traditional modems once used frequently with dial-up networks convert analog data from telephone lines into computer digital data. Broadband modems transfer digital data between two digital devices.
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: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:Charles Babbage invented the first mechanical computer, called the Difference Engine, in 1821 and completed it in 1832. The Difference Engine could perform simple calculations and compile mathematical tables. Babbage later conceived the Analytical Engine, a device that could perform any calculation, but was unable to construct a prototype during his lifetime.
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: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:A gigabyte is much larger than a megabyte. According to the National Institute of Standards and Technology, there are 1000 megabytes in a gigabyte. However, in some cases, a gigabyte is defined as 1024 megabytes.
A:The best way to destroy a hard drive is to magnetically degauss it first. If a hard drive is passed through a very strong magnetic field, the data on it will be permanently destroyed. The platters that spin the drive should then be physically destroyed.
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: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.
