The term used to describe a satellite, launched by Japan, that is capable of providing Internet connectivity at speeds of 1.2 GB/sec around the world. Called the WINDS satellite, it was first launched in February 2008 and it initially focused on providing Internet connectivity in the Asia-Pacific region. It’s a joint venture between two companies — Japan Aerospace Exploration Agency (JAXA) and Mitsubishi Heavy Industries.
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.
A symbol or character that appears slightly above a line, as in this example: r2. Footnote numbers appearing in text are also superscripts. A symbol or character that appears slightly below a line is called a subscript.
