While attending Harvard University, Bill Gates developed a version of the programming language BASIC. Gates' version of BASIC was for MITS Altair, the first microcomputer. He did not write any other programming languages.
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:Earphones, or headphones, work similarly to speakers in that they turn electrical energy into sound by using magnetism and the vibration of air. While a large speaker vibrates the air in the space around it to create sound, a pair of earphones only vibrates the air inside the ear canal. Earphones are usually designed as either closed-back or open-back, which affects how much sound can escape from them.
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 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: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:Automated systems eliminate the need for human interference in order to complete a task. Several industries use automated systems to increase production and reduce costs. A common example is an ATM, which can process banking transactions without a teller.
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: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 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:Computer limitations and capabilities are purely controlled by programming, user input and current advances in computer technology that limit hardware. The main limit to computers is that user input is needed for the performance of tasks because computers are not self-actualizing. Self-actualization is necessary in achieving artificial intelligence.
A:Strategic information systems are the information systems that companies use to help achieve their goals and become more efficient. Businesses use these systems to achieve a competitive advantage on their competitors as they seek to provide a good or service in a way that is better than that of their competition. For example, a strategic information system can be used to provide a product at a lower cost than competing organizations.
A:Computer literacy is important because most companies perform daily duties in an increasingly digitized manner. Employees that are comfortably and confidently able to master many computer programs are highly desired. To develop computer literacy or enhance skill-sets, basic computer courses and software tutorials are key to bolstering marketable skills.
A:A hard disk drive, also known as a hard drive or HDD, is used to store data long term. Data can include the computer's operating system and applications as well as personal files including photographs, documents and music. When a computer is booted up, or turned on, the computer access the hard drive to load the operating system, such as Windows, OSX or Linux.
A:Transmission media is the material pathway that connects computers, different kinds of devices and people on a network. It can be compared to a superhighway carrying lots of information. Transmission media uses cables or electromagnetic signals to transmit data.
A:The main difference between SD memory cards and XD memory cards pertains to capacity and speed. Generally, SD memory cards have a greater capacity and faster speed than XD memory cards, according to Photo Technique.
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:The first 8-inch floppy disks created in the 1970s had a capacity of 80 kilobytes. By 1986, IBM improved its design, resulting in the 3.5-inch floppy disk, which had a maximum capacity of 1.44 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.
