Nexus Hawk

Nexus Hawk 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 Nexus Hawk rather than just read about it. In short: The Nexus Hawk 4G is a gateway router linking broadband cellular data, such as CDMA, GSM and Wi-Fi (IEEE 802.11)a, b, g, n) and WAN (such as BGAN Satellite) networks providing enterprises with broadband wireless internet/network data services in mobile and remote environments. The Nexus Hawk's original development was funded under a DOD (Department of Defense) prime contract.

Key takeaways

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

Reference excerpt

The Nexus Hawk 4G is a gateway router linking broadband cellular data, such as CDMA, GSM and Wi-Fi (IEEE 802.11)a, b, g, n) and WAN (such as BGAN Satellite) networks providing enterprises with broadband wireless internet/network data services in mobile and remote environments. The Nexus Hawk's original development was funded under a DOD (Department of Defense) prime contract. The technology was primarily designed for military use and supports public safety. The Nexus Hawk is currently in use by law enforcement agencies, governmental data infrastructure, commercial fleet, connectivity in and to retail locations, and livery services in Washington, DC. The device provides secure access to public and private wired and wireless networks including, Sprint (CDMA EVDO Rev A, 1xRTT), Verizon Wireless LTE, CDMA EVDO Rev A 1xRTT, AT&T Wireless 4G, GSM /HSDPA, Telus HSDPA+, CDMA EVDO Rev A 1xRTT, Washington DC EVDO Rev A Regional Wireless Broadband Network (RWBN), non-U.S. cellular networks, and secure WiFi. GPS for applications such as Automatic Vehicle Location (AVL) sometimes commercial referred to as fleet tracking or Geo-Based Dispatch and Navigation. Connectivity to multiple simultaneous WAN via Gigabit Ethernet, USB or WiFi paths with user-selectable order for failover and fail back. Access to 4 simultaneous WANS and GPS. Automatic and persistent network connections. Incorporates 2 USB and 4 PCI-M slots to accommodate future networks such as WiMAX and Public Safety Band), accepts ExpressCard 34mm air cards, PCMCIA CardBus air cards and USB air cards via adapter, Secure Remote Configuration Management, Built in IPsec and OpenVPN and pass through security features, FIPS140-2 SSL Certified Module.

Worked examples

Example 1 — a first encounter with Nexus Hawk

Start with the simplest possible case. Write down what Nexus Hawk 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 Nexus Hawk 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 Nexus Hawk 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 Nexus Hawk

In research: Nexus Hawk 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 Nexus Hawk 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: Nexus Hawk is common in secondary-school and first-year university syllabi. It links to neighbouring topics Networking companies of the United States, Telecommunication infrastructure stubs, Telecommunications equipment, so understanding it makes those chapters shorter.
In everyday life: Look for Nexus Hawk 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 Nexus Hawk in simple terms?

Why does Nexus Hawk 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.
