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 ....

Opinion on Valentine's Day is somewhat mixed. Some may call it a contemptible symbol of consumerism that commodifies human emotion for financial gain. Others embrace the opportunity to show their loved ones they care. Some people just use it as an excuse to awkwardly ask out their office crush.
What you can't really do, though, is ignore it. Saccharine love ballads are pumped into food courts, heart shaped balloons festoon shop floors. You might want to pretend it doesn't exist, but it can be rather hard.
You may be thinking that the noble pursuit of truth and knowledge would get in the way of some good old-fashioned romance. You would be wrong; even scientists occasionally enjoy the odd dangerous liaison. So to commemorate this glorious celebration of love, WIRED is taking a look at some of the conveniently timed scientific studies to come out the week before Valentine's Day.

At a blistering 1.125 terabytes per second, a new optical communication system developed by University College London (UCL) researchers has created a new record for the fastest ever data transfer rate for digital information. At the quoted rate, say the researchers, the entire HD series of the TV show Game of Thrones could be downloaded in less than one second.

Electronic luggage tag lets travelers check-in bags from home
Expensive travel bags should do more than look good, and German high-end luggage manufacturer Rimowa would seem to agree. The company has developed an electronic luggage tag which displays baggage info in the same format, size and appearance of typical paper labels, but on a digital screen built into the unit and located near the handle.
