Tandberg

Tandberg is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tandberg rather than just read about it. In short: Tandberg was an electronics manufacturer located in Oslo, Norway (production, sales and distribution) and New York City, United States (sales and distribution). The company began in the radio field, but became more widely known for their reel-to-reel tape recorders as well as cassette decks and televisions.

Key takeaways

  • Tandberg belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Tandberg to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Tandberg from memory before moving on to harder problems.

Reference excerpt

Tandberg was an electronics manufacturer located in Oslo, Norway (production, sales and distribution) and New York City, United States (sales and distribution). The company began in the radio field, but became more widely known for their reel-to-reel tape recorders as well as cassette decks and televisions. The original company went bankrupt in 1978, after a sharp financial downturn. The following year, the company re-formed whilst its data division was split off as Tandberg Data, including the tape recording division, which reduced its scope to data recording. Over time the original Tandberg company became increasingly involved in the teleconferencing systems, and became a leader in that field. The company's main competitor was Polycom and other competitors were HP, Sony, Radvision, VTEL and Aethra. Cisco Systems acquired Tandberg on 19 April 2010. Tandberg Data became a German company dedicated to making computer tape storage systems.

History

Tandbergs Radiofabrikk The company was founded by Vebjørn Tandberg as Tandbergs Radiofabrikk (Tandberg's Radio Factory) in Oslo in 1933. The company's first radio was named "Tommeliten" (Tom Thumb), and used only earphones. This was followed by the "Corona" with a loudspeaker. In 1934, the first "Huldra" radio was launched, followed in 1936 by the "Sølvsuper". During the early years, radios, loudspeakers and microphones were the main output from the factory. The Sølvsuper and the Huldra radios became the foundation for Tandberg's success. In the early 1950s, Tandberg opened a branch plant at Kjelsås (in Oslo) to produce reel-to-reel tape recorders. Their first model was introduced to the market in 1952. Over the next decade, Tandberg quickly incorporated a number of leading-edge concepts; the model 2 Hi-Fi of 1956 had three tape transport speeds, allowing improved high-frequency response. The model 3 Stereo from 1957 was Tandberg's first stereo system which allowed playback of stereo tapes, however the ability to record in stereo was not made available until the introduction of the model 5 in 1958, which allowed for the connection of an external recording amplifier to record the second channel onto the tape. Their first full stereo system, the model 6 of 1960, featured four amplifiers, two for recording and two for playback respectively, giving the operator total control of both audio channels. In the 1960s, Tandberg introduced the cross-field recording technique in the model 6X, allowing its recorders to handle higher frequencies than competing models. Tandberg licensed the concept to Akai, who utilized it extensively in the 1970s and 80s, in their Akai and Roberts recorders. In 1964, Tandberg inaugurated a new method of language teaching, the language laboratory, and with it its first fully transistorized tape recorder, the model 10, a recorder designed to serve as the teacher recorder in language classrooms. However the first transistorized recorder marketed to consumers was the model 12 of 1966, which among other things featured low impedance microphone inputs, designed for its first dynamic microphone, the TM 4. In 1969, Tandberg finally abandoned the use of vacuum tubes in its recorders, and the 6X which had introduced cross-field recording to the world, the last tube recorder still manufactured by Tandberg, went out of production. That same year a new lineup of transistorized Tandberg recorders entered the market to fill the gap left by the preceding models. Tandberg tape recorders dominated the Norwegian market, and had a reputation for advanced technology and high quality at reasonable prices. It was on Tandberg reel-to-reel machines that President John F. Kennedy recorded many meetings in the Cabinet Room of the White House, including those associated with the Cuban Missile Crisis. The Kjelsås factory also started producing TV sets in 1960, and in 1966, a second TV plant was opened in Kjeller in Skedsmo. Colour TV's were added to its lineup in 1969. In 1972, Tandberg purchased Radionette, another large Norwegian electronics firm now focusing on televisions. By 1976, TVs were Tandberg's major product and its factories employed 3,500. However, that same year a major economic downturn seriously disrupted the company, and by 1978, it was insolvent. A shareholder revolt removed Vebjørn Tandberg from control of the company, and he committed suicide in August. In December, the company declared bankruptcy.

Split-up In the aftermath of the bankruptcy, the original Tandberg was split into two parts. Under the control of Siemens, Tandberg Data took over the computer terminal and tape recording parts of the company, moving the latter purely into the computer storage field. The remaining portions went under control of Norsk Data and lost the "Radiofabrikk" to become, simply, Tandberg. Tandberg continued to develop audio technology including Actilinear and Dyneq. In 1984, the consumer audio equipment division was spun off to become Tandberg Audio.

Worked examples

Example 1 — a first encounter with Tandberg

Start with the simplest possible case. Write down what Tandberg claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tandberg before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tandberg ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tandberg

In research
Tandberg appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Tandberg in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Tandberg is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1933 establishments in Norway, 2010 mergers and acquisitions, Cisco acquisitions, so understanding it makes those chapters shorter.
In everyday life
Look for Tandberg outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
