Samuel Fedida

Samuel Fedida 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 Samuel Fedida rather than just read about it. In short: Samuel Fedida, OBE (4 May 1918 – 10 August 2007) was an Egyptian-born British telecommunication engineer responsible at Post Office Telecommunications for the development of Viewdata. Fedida was born in Alexandria, Egypt.

Key takeaways

Samuel Fedida 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 Samuel Fedida to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Samuel Fedida from memory before moving on to harder problems.

Reference excerpt

Samuel Fedida, OBE (4 May 1918 – 10 August 2007) was an Egyptian-born British telecommunication engineer responsible at Post Office Telecommunications for the development of Viewdata. Fedida was born in Alexandria, Egypt. He had the idea for Viewdata in 1968 after reading a publication with the title The Computer as Communications Device. The first prototype became operational in 1974. In 1977 the system was introduced in the United Kingdom. He was appointed an Officer of the Order of the British Empire in the 1980 Birthday Honours. The book Viewdata Revolution authored by Fedida and Rex Malik, ISBN 0852272146, was published in 1979. He died in 2007 in Hemel Hempstead.

Worked examples

Example 1 — a first encounter with Samuel Fedida

Start with the simplest possible case. Write down what Samuel Fedida 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 Samuel Fedida 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 Samuel Fedida 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 Samuel Fedida

In research: Samuel Fedida 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 Samuel Fedida 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: Samuel Fedida is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1918 births, 2007 deaths, 20th-century Egyptian Jews, so understanding it makes those chapters shorter.
In everyday life: Look for Samuel Fedida 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.
