George Amaro

George Amaro 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 George Amaro rather than just read about it. In short: George Corrêa Amaro is a Brazilian computer scientist responsible for the connection of Roraima (Brazilian Amazon) to the Internet. Biography Amaro began his data communication work on the state of Roraima in 1985, when he connected an Apple II microcomputer in the service of "Video Texto" of Telesp and a microcomputer TRS-80 in "Projeto Cirandão" of Embratel.

Key takeaways

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

Reference excerpt

George Corrêa Amaro is a Brazilian computer scientist responsible for the connection of Roraima (Brazilian Amazon) to the Internet.

Biography Amaro began his data communication work on the state of Roraima in 1985, when he connected an Apple II microcomputer in the service of "Video Texto" of Telesp and a microcomputer TRS-80 in "Projeto Cirandão" of Embratel. At Embrapa Roraima, he developed a connection between the first corporate local area network of the state in 1991, in a client-server architecture (a 386/DX 33Mhz server with 8MB RAM and 80GB HD MFM connected through a network Amplus to 3 12 MHz PC/XT). In 1992, he was responsible for the introduction of free and open source software in the state of Roraima, and set up the first Intel 386 PCs running Unix (SCO), which then became the first Linux server. Also in 1992, he made the first Internet connection and Web access in Roraima, with the support of Embratel, using RENPAC 2000 and implementing TCP/IP on a PC. The method used was to create a TCP/IP tunnel over RENPAC, connecting a PC at his home to a minicomputer at Embrapa Informática Agropecuária (which was connected with FAPESP). Together with two friends, Marcus Vinicius Quintella and João Claver, he designed and implemented the first Internet Service Provider (ISP) in Roraima, TechNet, in 1996, with servers based entirely on open source software. He left the company in December 2004, but all that has been built yet kept working. With TechNet, he configured and operated the first Internet-connected servers in Roraima, and authored the official website of the State of Roraima in 1997. Embryos arose from social networks, through online chat services, thus creating the first IRC server for Roraima in 1997, connecting to the Brasnet network, with the first channel chat being about the state and the then well known Canal Roraima (#Roraima). Online games were also introduced, with the creation of the first Quake server in Roraima in 1999. In 2001, he and his colleagues designed and implemented one of the first wireless (WiFi) networks for public access in Roraima, initiating the first broadband connections. With the evolution of the Internet and the possibility of creating dynamic sites, he created the first information portal for the State of Roraima in January 2002, based on PHP and MySQL.

Worked examples

Example 1 — a first encounter with George Amaro

Start with the simplest possible case. Write down what George Amaro 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 George Amaro 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 George Amaro 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 George Amaro

In research: George Amaro 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 George Amaro 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: George Amaro is common in secondary-school and first-year university syllabi. It links to neighbouring topics Brazilian academic biography stubs, Brazilian computer scientists, Computer scientist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for George Amaro 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.
