Wireless is an
old-fashioned term for a radio
receiver, referring to its use as a wireless telegraph. The term is
widely used to describe modern wireless connections such as wireless broadband internet. History
The founding principles and inventions of wireless
technology can be found in the lectures and patent record of the electrical engineer
Nikola Tesla and in his
1916 deposition on the history of
wireless and radio technology,
which was earlier pioneered by Jagdish Chandra Bose
and Guglielmo Marconi.
A wireless set was the radio receiver,
referring to its use as a wireless telecommunication
station. The term "wireless" was widely used in the UK, long after radio was being used
for other signals, such as music.
The British phrase "wireless telegraphy" is one
of those which, like aerodrome,
was effortlessly transferrable between British and French forces during WWI, but which couldn't quite make
it across the Atlantic to become fully accepted into American English. The
French equivalent was télégraphie sans
fil, which word-for-word translates as "telegraphy without wire."
The British abbreviation, used by the military, was W/T. (When voice became transmittable over radio waves, the phrase
used in the same era was "radio telephony," whose British
abbreviation was R/T.)

PDA
(Personal Digital Assistant) A handheld computer that serves as an organizer for
personal information. It generally includes at least a name and address
database, to-do list and note taker. PDAs may be combined with cellphones and
other wireless technologies, providing a mobile office for people on the go. 
PDAs are pen based and use a stylus to tap selections on
menus and to enter printed characters. The unit may also include a small
on-screen keyboard which is tapped with the pen. Data are synchronized between
the PDA and desktop computer via cable or wireless transmission.
A PDA is like a palmtop computer except that the PDA
typically uses a pen whereas the palmtop uses a small keyboard. Apple's
MessagePad, more commonly known as the "Newton," was the pioneer in
this field in 1993. However, PalmPilots, introduced a couple years after,
popularized the technology. See Newton
and Palm.

The next version of Windows 7 that Microsoft releases to the world will be the release candidate – not just another beta.
The Windows 7 Beta was first released last month, with the download period extended to next week.
Steven Sinofsky, head of the Windows development team, said in a blog post that he was looking to assuage concerns that users would have to revert back to their “old” operating system when the beta expires in August. Stressing that he was not announcing a ship date – or indeed, any change of plans – Sinofsky said that the next version will indeed be the release candidate (RC). |
