Objective Interface Systems

Objective Interface Systems 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 Objective Interface Systems rather than just read about it. In short: Objective Interface Systems, Inc. is a computer communications software and hardware company. The company's headquarters are in Herndon, Virginia, USA.

Key takeaways

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

Reference excerpt

Objective Interface Systems, Inc. is a computer communications software and hardware company. The company's headquarters are in Herndon, Virginia, USA. OIS develops, manufactures, licenses, and supports software and hardware products that generally fit into one or more of the following markets:

Real-time communications middleware software and hardware Embedded communications middleware software and hardware High-performance communications middleware software and hardware Secure communications software and hardware A popular OIS product is the ORBexpress CORBA middleware software. ORBexpress is most popular in the real-time and embedded computer markets. OIS supports the software version ORBexpress on more than 6,000 computing platforms (combinations of the versions of CPU families, operating systems, and language compilers). OIS also has FPGA versions of ORBexpress to allow hardware blocks on an FPGA to interoperate with software. OIS engineers invented a form of communications security called the Partitioning Communication System or PCS. The PCS is a technical architecture that protects multiple Information Flows from influencing each other when communicated on a single network wire. The PCS is best implemented on a software separation operating system such as SELinux or a separation kernel. OIS's communications products are most frequently found in the enterprise, telecom/datacom, mil/aero, medical, robotics, process control and transportation industries. Objective Interface is a privately held company and has developed software products since 1989 and hardware products since 2001. The company is actively involved with various standards groups including:

Common Criteria IEEE Network Centric Operations Industry Consortium Object Management Group (OMG) The Open Group Wireless Innovation Forum

Corporate Headquarters OIS headquarters is located at 220 Spring Street, Herndon, VA, 20170-6201.

Worked examples

Example 1 — a first encounter with Objective Interface Systems

Start with the simplest possible case. Write down what Objective Interface Systems 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 Objective Interface Systems 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 Objective Interface Systems 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 Objective Interface Systems

In research: Objective Interface Systems 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 Objective Interface Systems 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: Objective Interface Systems is common in secondary-school and first-year university syllabi. It links to neighbouring topics Common Object Request Broker Architecture, Companies based in Fairfax County, Virginia, Computer hardware companies, so understanding it makes those chapters shorter.
In everyday life: Look for Objective Interface Systems 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.
