The fastest type of computer. Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations. For example, weather forecasting requires a supercomputer. Other uses of supercomputers include animated graphics, fluid dynamic calculations, nuclear energy research, and petroleum exploration. The chief difference between a supercomputer and a mainframe is […]
Short for Classless Inter-Domain Routing, an IP addressing scheme that replaces the older system based on classes A, B, and C. With CIDR, a single IP address can be used to designate many unique IP addresses. A CIDR IP address looks like a normal IP address except that it ends with a slash followed by […]
In magnetic disk drive storage technology, the fluctuation of magnetization due to thermal agitation. When the areal density — the number of bits that can be stored on a square inch of disk media — of a disk medium reaches 150 gigabits per square inch, the magnetic energy holding the bits in place on the […]
Refers to microprocessor architectures that enable more than one instruction to be executed per clock cycle. Nearly all modern microprocessors, including the Pentium, PowerPC, Alpha, and SPARC microprocessors are superscalar.
