N. Seshagiri

N. Seshagiri 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 N. Seshagiri rather than just read about it. In short: Narasimaiah Seshagiri (10 May 1940 – 26 May 2013) was an Indian computer scientist, writer and a former director-general of the National Informatics Centre, an apex organization of the Government of India, handling its e-governance applications. He was a member of the Y2K Action Force of the Government, formed to combat the 9999 computer bug.

Key takeaways

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

Reference excerpt

Narasimaiah Seshagiri (10 May 1940 – 26 May 2013) was an Indian computer scientist, writer and a former director-general of the National Informatics Centre, an apex organization of the Government of India, handling its e-governance applications. He was a member of the Y2K Action Force of the Government, formed to combat the 9999 computer bug. He is credited with many publications which included The bomb! : fallout of India's nuclear explosion and Information systems for economies in transition. The Government of India awarded him the third highest civilian honour of the Padma Bhushan, in 2005, for his contributions to science and technology.

Worked examples

Example 1 — a first encounter with N. Seshagiri

Start with the simplest possible case. Write down what N. Seshagiri 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 N. Seshagiri 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 N. Seshagiri 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 N. Seshagiri

In research: N. Seshagiri 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 N. Seshagiri 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: N. Seshagiri is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1941 births, 20th-century Indian non-fiction writers, Computer scientist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for N. Seshagiri 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.
