Basic Computer

A capacitive keyboard is a type of computer keyboard that uses a change of capacitance on the capacitor pad to detect a pressed key on a keyboard. It provides functionality similar to a standard contact keyboard, but its internal structure is different and is fairly quicker and more reliable.

Humanware is hardware and software that emphasizes user capability and empowerment and the design of the user interface. The process of building humanware generally consists of these steps:
1. Define users (age, mindset, environmental context, previous product experience and expectations, and so forth) and what they really want to do.
2. Identify tasks they will need to do or capabilities they will want
3. Specify usability objectives (if possible, these should be measurable, such as how long to do something or how many mouse clicks to get to a specified task point) for each task or capability.
4. Build a prototype of the user interface (it can be a paper or simulated prototype if time is short)
5. Test and verify or correct the prototype
6. Provide the prototype and usability objectives to the program designers and coders.

A supercomputer is a computer with a high level of performance compared to a general-purpose computer. Performance of a supercomputer is measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS).

In 1945, Professor J. von Neumann, who was then working at the Moore School of Engineering in Philadelphia, where the E.N.I.A.C. had been built, issued on behalf of a group of his co-workers, a report on the logical design of digital computers.
