Network service provider

Network service provider 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 Network service provider rather than just read about it.

Reference excerpt

Network service provider (NSP) is one of the roles defined in the National Information Infrastructure (NII) plan, which governed the transition of the Internet from US federal control to private-sector governance, with an accompanying shift from the 1968-1992 single-payer economy to a competitive market economy. The plan envisioned network service providers as a wholesale layer, moving Internet bandwidth produced at Network Access Points (subsequently called "Internet exchange points") to Internet service providers, who would in turn sell it to end-user enterprises, or on to Internet Access Providers (IAPs) who would sell it to individual end-users in their homes. In fact, the original Network Service Providers quickly vertically integrated with Internet service providers and Internet Access Providers, through the mid-1990s, creating conglomerates and reducing competition. Now, the term may refer to telecommunications companies, data carriers, wireless communications providers, Internet service providers, and cable television operators offering Internet access.

Worked examples

Example 1 — a first encounter with Network service provider

Start with the simplest possible case. Write down what Network service provider 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 Network service provider 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 Network service provider 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 Network service provider

In research: Network service provider 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 Network service provider 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: Network service provider is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer network stubs, Network access, Telecommunications companies, so understanding it makes those chapters shorter.
In everyday life: Look for Network service provider 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.
