Silence (software)

Silence (software) 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 Silence (software) rather than just read about it. In short: Silence was a free, open-source messaging encryption software, based on a fork from TextSecure software. It allowed the secure exchange of SMS and MMS-type messages with other Silence or TextSecure users.

Key takeaways

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

Reference excerpt

Silence was a free, open-source messaging encryption software, based on a fork from TextSecure software. It allowed the secure exchange of SMS and MMS-type messages with other Silence or TextSecure users. The program allowed message encryption and identity verification between correspondents by comparing the fingerprint of the encryption keys.

History TextSecure started as an application for sending and receiving encrypted SMS messages in 2015. However, its beta version was released in May 2010, by Whisper Systems, a startup co-founded by security researcher Moxie Marlinspike and roboticist Stuart Anderson. The software was therefore published under a free and open-source license, under the terms of the GPLv3 in December 2011. Marlinspike left Twitter to create Open Whisper Systems as a collaborative open-source project, enabling the development of TextSecure. The Open Whisper Systems institutional website was presented to the public in January 2013. The port of TextSecure to iOS started in March 2013.

Worked examples

Example 1 — a first encounter with Silence (software)

Start with the simplest possible case. Write down what Silence (software) 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 Silence (software) 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 Silence (software) 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 Silence (software)

In research: Silence (software) 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 Silence (software) 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: Silence (software) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cryptographic software, Free and open-source software stubs, Free software programmed in Java, so understanding it makes those chapters shorter.
In everyday life: Look for Silence (software) 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.
