Key takeaways

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

Reference excerpt

Opengear is a global computer network technology company headquartered in Sandy, Utah, U.S., with engineering in Brisbane, Qld, Australia. The company develops and manufactures "smart out-of-band infrastructure management" products aimed at allowing customers to securely access, control and automatically troubleshoot and repair their IT infrastructure remotely, including network and data-center management, for resilient operation. Opengear solutions provide always-available wired and wireless secure remote access, with failover capabilities to automatically restore site connectivity. This enables technical staff to provision, maintain and repair infrastructure from anywhere at any time, as if they were physically present, thereby enabling both the operational costs and the risk of downtime to be reduced. In December 2019, Opengear was acquired by Digi International.

Products Opengear's management products include IM7200 advanced console servers that streamline management of network, server, and power infrastructure in data centers and colocation facilities; and ACM7000 remote management gateways that deliver secure remote monitoring, access and control of distributed networks and remote sites. The Lighthouse Centralized Management platform then provides a single point of scalable, secure management for these Opengear appliances and connected devices. The Opengear NetOps Console Server combine out-of-band management and NetOps tools in a single appliance, minimizing human intervention and simplifying repetitive tasks. All Opengear products provide a secure alternate out-of-band path to the managed infrastructure, enabling accessibility even during system or network outage. They monitor, access, and control all critical infrastructure at all local and remote sites, from applications, computers and networking equipment, to security cameras, power supplies and door sensors - to proactively detect faults and remediate before they become failures. Opengear's products are built on a Linux software base, and the company is an active supporter of the open-source community.

Worked examples

Example 1 — a first encounter with Opengear

Start with the simplest possible case. Write down what Opengear 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 Opengear 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 Opengear 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 Opengear

In research: Opengear 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 Opengear 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: Opengear is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2004 establishments in New Jersey, Computer companies of the United States, Computer hardware companies, so understanding it makes those chapters shorter.
In everyday life: Look for Opengear 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.
