Information technology

The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones.

History of computer technology

Devices have been used to aid computation for thousands of years, probably initially in the form of a tally stick. The Antikythera mechanism, dating from about the beginning of the first century BC, is generally considered to be the earliest known mechanical analog computer, and the earliest known geared mechanism.

Data storage

Early electronic computers such as Colossus made use of punched tape, a long strip of paper on which data was represented by a series of holes, a technology now obsolete. Electronic data storage, which is used in modern computers, dates from World War II, when a form of delay line memory was developed to remove the clutter from radar signals, the first practical application of which was the mercury delay line.

Databases

Database management systems emerged in the 1960 to address the problem of storing and retrieving large amounts of data accurately and quickly. One of the earliest such systems was IBM's Information Management System (IMS), which is still widely deployed more than 40 years later. IMS stores data hierarchically,

Academic perspective

In an academic context, the Association for Computing Machinery defines IT as "undergraduate degree programs that prepare students to meet the computer technology needs of business, government, healthcare, schools, and other kinds of organizations ....

NASA trains pilots with Fused Reality

Scott Howe performs a task with the Fused Reality system

To gain proficiency, pilots need realistic training, but they also need to avoid needless cost and risk. Real aircraft provide the most obviously realistic training, but they're dangerous in inexperienced hands. Meanwhile, simulators can reproduce much of the look and feel of actual flying without the danger of losing an aircraft or pilot, but they aren't as successful when it comes to complex maneuvers like aerial-refueling. To square the circle, NASA is developing a technology called Fused Reality, which uses a special headset that combines real flying in a real aircraft with an overlaid simulation.

Can we build a complete wiring diagram of the human brain?

A map of the connectomes within a human brain

Our brains are wondrous, incredible machines. They're slower than the earliest personal computers in terms of raw processing power, yet capable of leaps of intuition and able to store a lifetime of memories that are cross-referenced and instantly-accessible at the slightest prompting. We know so very little about how they do these things, however. But imagine for a moment if we could build a complete wiring diagram of a human brain – to map in detail every one of the hundred trillion or so synapses and roughly hundred billion neurons together with all the tiniest supporting mechanisms. What might that mean, and would it even be possible?

Review: B&W P5 Wireless headphones offer crisp and clear cable-free listening

Gizmag takes the P5 Wireless headphones from Bowers and Wilkins for a spin

Many companies have leaped gleefully into the choppy, Bluetooth-tinted waters of personal wireless listening, but Bowers & Wilkins has made a more measured entry.

After spending some time with the plush leather pads pressed against our ears, we've got some thoughts on how they stack up, and we feel devotees of the company's high-end equipment won't be disappointed with its decision to cut the cord.
