Virtual Interface Adapter

Virtual Interface Adapter 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 Virtual Interface Adapter rather than just read about it. In short: A Virtual Interface Adapter (VIA) is a network protocol (such as TCP/IP ...) supported by Microsoft SQL Server since July 2005. The specific implementation of VIA will vary from vendor to vendor.

Key takeaways

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

Reference excerpt

A Virtual Interface Adapter (VIA) is a network protocol (such as TCP/IP ...) supported by Microsoft SQL Server since July 2005. The specific implementation of VIA will vary from vendor to vendor. In general, it is usually a network kind of interface but is usually a very high-performance, dedicated connection between two systems. Part of that high performance comes from specialized, dedicated hardware that knows that it has a dedicated connection and therefore doesn't have to deal with normal network addressing issues.

The VIA protocol is used to support VIA devices, such as VIA Storage Area Network devices. Comes in the concept of clustering (i.e.) load balancing method. The load balancer will have this VIA and through VIA it will connect the databases. The VIA protocol is deprecated by Microsoft, and will be removed in a future version of Microsoft SQL Server. It is however supported in SQL Server 2008, SQL Server 2008 R2, SQL Server 2012, and SQL Server 2014.

Worked examples

Example 1 — a first encounter with Virtual Interface Adapter

Start with the simplest possible case. Write down what Virtual Interface Adapter 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 Virtual Interface Adapter 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 Virtual Interface Adapter 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 Virtual Interface Adapter

In research: Virtual Interface Adapter 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 Virtual Interface Adapter 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: Virtual Interface Adapter is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer network stubs, Computing stubs, Network protocols, so understanding it makes those chapters shorter.
In everyday life: Look for Virtual Interface Adapter 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.

Frequently asked questions

What is Virtual Interface Adapter in simple terms?

A Virtual Interface Adapter (VIA) is a network protocol (such as TCP/IP ...) supported by Microsoft SQL Server since July 2005. The specific implementation of VIA will vary from vendor to vendor.

Why does Virtual Interface Adapter matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Virtual Interface Adapter?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
