Reference excerpt

This is a Glossary of Internet Terminology; words pertaining to Internet Technology, a subset of Computer Science.

A–M

ADSL Asymmetric Digital Subscriber Line is a technology for transmitting digital information at a high bandwidth on existing phone lines to homes and businesses. ADSL is asymmetric in the sense that it uses most of the channel to transmit downstream to the user and only a small part to receive information from the user. This means, high download rates and slower upload rates. Generally if you see 2 Mb ADSL broadband, it refers to 2 Mbit/s Max d/load rate. The upload rate will probably be around 256 kbit/s Max. (ADSL has a maximum download rate of 8 Mbit/s, ADSL2 is capable of up to 16 Mbit/s and ADSL2+ is rated at 24 Mbit/s maximum.)

Bandwidth (computing) Rate data transfers across a network

Blogging Writing on or otherwise using online journals known as web logs or blogs

Cable modem Primary competitor to ADSL, uses digital information transmitted over a cable television infrastructure.

CSS Cascading Style Sheets; while HTML dictates the content of page, CSS regulates the format, including headers, footers, navigation bars, etc. While all of these elements can be created in HTML, such a method would have to be repeated on every web page. CSS on the other hand, is applied to all pages of a website.

Cyberbullying A bully who harasses his or her victims online through various means such as spamming, defaming or negative impersonation of the victim.

Dial-up A method of connection to the internet using existing copper phone lines using a modem on the client's end to send information at a slow speed, normally reaching maximum speed at about 56 kbit/s. This technology uses the voice spectrum of the telephone lines to transmit data using a system of sounds that only the receiving modem or ISP understand.

Egosurfer someone who searches the Internet for references of themselves

Fail The opposite of "win", "fail" expresses an ability to incorrectly perform acts ranging from idiotically simple to impossibly difficult, often consisting of an amusing element.

HTML HyperText Markup Language, the coding language used to create hypertext documents for the World Wide Web. In HTML, a block of text can be surrounded with tags that indicate how it should appear (for example, in bold face or italics). Also, in HTML a word, a block of text, or an image can be linked to another file on the Web. HTML files are viewed with a World Wide Web browser.

ID-10-T clueless user; everybody giving a hard time to (computer) administrators

Jank flickering in a user interface, due to the software generating the interface being unable to update quickly enough for the display's frame rate.

Lag perceived poor response times or sluggishness in a user interface, which may be due to programming defects, use of low-quality processes, executing long tasks. Often this slows down or affects user performed operations.

Leet Leet, or "1337", (from elite) is someone who is unnaturally adept at a certain trait or ability. Originally used as a slightly infra dig expression in the hacker community. Later usage centered around video games players.

Lurk Used to describe visiting and spending time on forums and image boards viewing content but not posting. People engaged in this are called "lurkers".

N–Z noob A new or inexperienced person, someone who does not know the rules of a website, or has only recently joined. A wordplay on newbie.

Worked examples

Example 1 — a first encounter with Glossary of Internet-related terms

Start with the simplest possible case. Write down what Glossary of Internet-related terms 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 Glossary of Internet-related terms 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 Glossary of Internet-related terms 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 Glossary of Internet-related terms

In research: Glossary of Internet-related terms 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 Glossary of Internet-related terms 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: Glossary of Internet-related terms is common in secondary-school and first-year university syllabi. It links to neighbouring topics Glossaries of computers, Internet slang, Internet terminology, so understanding it makes those chapters shorter.
In everyday life: Look for Glossary of Internet-related terms 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.
