Computing Fundamentals 2 Exam Questions With 100% Correct Answers. Output Device - answerAny device used to send data from a computer to another device or user. Examples include monitors, projectors, speakers, headphones and printers. Output - answerData generated by a computer. The most commonly used output devices are the computer's monitor, printer, and computer speakers. Hard Drive - answerThe primary computer storage device, which spins, reads and writes one or more fixed disk platters. Flash drive - answerA small, portable flash memory card that plugs into a computer's USB port and functions as a portable hard drive. Magnetic Hard Drive - answerIs a data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material. SSD Drive - answerStands for "Solid State Drive." An SSD is a type of mass storage device similar to a hard disk drive (HDD). Instead of storing data on magnetic platters, SSDs store data using flash memory. Megahertz - answerOne million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. Gigahertz - answerWhen referring to a computer processor or CPU, GHz is a clock frequency, also known as a clock rate or clock speed, representing a cycle of time. Terahertz - answerOne terahertz is equal to 1,000 gigahertz (GHz). terahertz is more often used to measure the total speed of computing clusters or supercomputers. Petahertz - answerThis is a such a high unit of measurement, and present day computers can't "function" at this high of processing speed, yet. Bit vs Byte - answerA bit is the smallest unit of information that can be stored or manipulated on a computer; it consists of either zero or one. The bits are bunched together so the computer uses several bits at the same time, such as for calculating numbers. When a "bunch" means eight bits then it is called a byte. Supercomputers - answerIt is a high performance computing machine designed to have extremely fast processing speeds. Supercomputers have various applications, such as
