An application programming interface (API) is a protocol used as an

interface by software components to communicate with each other. In

other words, API is the binding agent across functional components

assembled similarly to Lego blocks.

Digital Simplicity

an API is a software brick that allows someone to share data, content and

functionalities with others, for them to build new services based on this

data, content and functionalities

First Laptop Computer

(/w MS Basic Interpreter written by

Bill Gates himself)

The Tandy 100 was a computer made in Japan by Kyocera. All the ROMprograms were written by Microsoft, and even a few of them were

written by Bill Gates himself ! These programs include a text editor, a

telecommunication program, which uses the built-in modem (300

baud), and a rather good version of BASIC .

The OS uses 3130 bytes of the 8 KB RAM. Tandy replaced the Tandy 100

with the Tandy 102 (which has 24 kb RAM)

First Portable Phone (Motorola Brick)

Model DynaTAC is a series of cellular telephonesmanufactured by Motorola, Inc. from 1983 to 1994.

The first model, the 8000x, received FCC certification in

1983, and became the first cell phone to be offered

commercially when it went on sale on 6 March 1983.

It offered 30 minutes of talk time and 8 hours of standby,

and a LED display for dialling or recall of one of 30 phone

numbers. It was priced at $3,995 in 1983. DynaTAC was

an abbreviation of Dynamic Adaptive Total Area

Coverage.

First Cellular Phone (car-

phone)

A car phone is a mobile phone device specifically designed for and fitted

into an automobile. This service originated with the Bell System, and was

first used in St. Louis on June 17, 1946. The original equipment weighed80 pounds (36 kg), and there were initially only 3 channels for all the

users in the metropolitan area

Phonograph

(Vinyl Record Player)

The phonograph, record player, or gramophone, is a device

introduced in 1877 for the recording and reproduction of sound

recordings. The recordings played on such a device generally consist

of wavy lines that are either scratched, engraved, or grooved onto arotating cylinder or disc. As the cylinder or disc rotates, a stylus or

needle traces the wavy lines and vibrates to reproduce the recorded

sound waves.Information Courtesy: Wikipedia, 2013

Vacuum Tube (Valve) Radio Receiver with License

During the mid-1920s, amplifying vacuum tubes (or thermionic valves

in the UK) revolutionized radio receivers and transmitters. John

Ambrose Fleming developed an earlier tube known as an "oscillation

valve" (it was a diode). Lee De Forest placed a screen, the "grid"

electrode, between the filament and plate electrode, creating the

triode.

Japanese PHS Phones:Inexpensive Wireless Digital Phones

PHS is essentially a cordless telephone like DECT, with the

capability to handover from one cell to another. PHS cells are

small, with transmission power of base station a maximum of

500 mW and range typically measures in tens or at most

hundreds of metres (some can range up to about 2 kilometres

in line-of-sight), contrary to the multi-kilometre ranges of CDMAand GSM. This makes PHS suitable for dense urban areas, but

impractical for rural areas, and the small cell size also makes it

difficult if not impossible to make calls from rapidly moving

vehicles.

Speak-and-Spell

(Frist Speech Synthesizer toy by TI)

The Speak & Spell used the first single-chip voice synthesizer, the TMC0280, later called the

TI TMS5100, which utilized a 10th-order linear predictive coding (LPC) model by using

pipelined electronic DSP logic. A variant of this chip with a very similar voice would

eventually be utilized in certain Chrysler vehicles in the 1980s as the Electronic Voice Alert.

LEGO Mindstorms(Robotic Invention Kit by LEGO)

The hardware and software roots of theMindstorms Robotics Invention System kit go back

to the programmable brick created at the MIT

Media Lab. This brick was programmed in Brick

Logo. The first visual programming environment

was called LEGOsheets, since it was created by the

University of Colorado in 1994 based onAgentSheets.

Developed in the 1950s, Fortran is a general-purpose programming language that is

especially suited to numeric computation and scientific computing. It was originally

developed for scientific and engineering applications, It came to dominate that area of

programming and is still in use in computationally intensive areas such as numerical

weather prediction, finite element analysis, computational fluid dynamics,computational physics and computational chemistry. It is one of the most popular

languages in the area of high-performance computing and is the language used for

programs that benchmark and rank the world's fastest supercomputers.

Floppy Drive (Diskette)

Floppy disks, initially as 8-inch (200 mm) media and later in 5.25-inch

(133 mm) and 3.5-inch (90 mm) sizes, were a ubiquitous form of datastorage and exchange from the mid-1970s well into the first decade of

the 21st century.

The line printer is a printer in which one lineof text is printed at a time.

Print speeds of 600 lines-per-minute

(approximately 10 pages per minute) were

achieved using these in the 1950s, later

increasing to as much as 1200 lpm.

These could print a complete line at a time

and have speeds in the range of 150 to 2500

lines per minute. The different types of line

printers are drum printers and chain printers.

First Low-cost Home Colour ComputerThe ZX81, released in a slightly modified form in the United States as the Timex

Sinclair 1000, was a home computer produced by Sinclair Research and

manufactured in Scotland by Timex Corporation. It was launched in the United

Kingdom in March 1981 as the successor to Sinclair's ZX80 and was designed to be

a low-cost introduction to home computing for the general public.

HAM (Amateur Radio) for Hobbyists

Display: Citizen Band (CB) Radio tweaked for HAM Communications

Amateur radio (also called ham radio) is the use of designated radio

frequency spectrum for purposes of private recreation, non-commercial

exchange of messages, wireless experimentation, self-training, and

emergency communication. The term "amateur" is used to specify persons

interested in radio technique solely with a personal aim and without directpecuniary interest, and to differentiate it from commercial broadcasting,

public safety (such as police and fire), or professional two-way radio services

(such as maritime, aviation, taxis, etc.).

The soroban (counting tray) is an abacus developed in Japan.

It is derived from the Chinese suanpan, imported to Japan

around 1600. Like the suanpan, the soroban is still used

today, despite the proliferation of practical and affordablepocket electronic calculators.

MIR Publishers(Extremely Popular Science Books from former USSR)

Text Books are necessary evil for most students, NOT

books from MIR Publishers from former USSR. Very

illustrative, explaining complex concepts with fun andsimple examples. Many students of 70-80s, developed

fascination with Soviet Union, not out of political ideology,

but for their most student-friendly books on Science,

Engineering and Maths.

Disposable Film Camera (1990s)

The disposable or single-use camera is a simple box camera sold

with a roll of film installed, meant to be used once. Most use

fixed-focus lenses. Some are equipped with an integrated flash

unit, and there are even waterproof versions for underwater

photography. Internally, the cameras use a 135 film or an APS

cartridge.

Portable (monochrome) GPS Device

A GPS navigation device is any device that receives Global

Positioning System (GPS) signals for the purpose of determining

the device's current location on Earth. GPS devices provide

latitude and longitude information, and some may also

calculate altitude, although this is not considered sufficiently

accurate or continuously available enough (due to the

possibility of signal blockage and other factors) to rely on

exclusively to pilot aircraft. GPS devices are used in military,

aviation, marine and consumer product applications.

Phreaking is a slang term coined to describe the activity of a culture of

people who study, experiment with, or explore telecommunication

systems, such as equipment and systems connected to public telephone

networks. As telephone networks have become computerized, phreakinghas become closely linked with computer hacking.

This is sometimes called the H/P culture (with H standing for hacking and

P standing for phreaking).

Thermionic Valve (Pentode)

In electronics, a vacuum tube, electron tube (in North America),

thermionic valve, tube, or valve is a device controlling electric

current through a vacuum in a sealed container.

The simplest vacuum tube, the diode, is essentially an incandescentlight bulb with an added electrode inside. When the bulb's filament

is heated white-hot, electrons are "boiled" off its surface and into

the vacuum inside the bulb. If the electrode -- called a "plate" or

"anode" -- is made more positive than the hot filament, a direct

current flows through the vacuum to the electrode (a demonstration

of the Edison effect). As the current only flows in one direction, itmakes it possible to convert an alternating current applied to the

filament to direct current.

The first truly pocket-sized electronic calculator was the Busicom LE-120A "HANDY",which was marketed early in 1971. Made in Japan, this was also the first calculator touse an LED display, the first hand-held calculator to use a single integrated circuit (thenproclaimed as a "calculator on a chip"), the Mostek MK6010, and the first electroniccalculator to run off replaceable batteries. Using four AA-size cells the LE-120A

measures 4.9x2.8x0.9 in (124x72x24 mm).

The first American-made pocket-sized calculator, the Bowmar 901B (popularly referred toas The Bowmar Brain), measuring 5.2 3.0 1.5 in (131 77 37 mm), came out in the

Autumn of 1971, with four functions and an eight-digit red LED display, for $240,
