Tunneling

The term "tunneling" probably brings to mind images of digging tunnels underground, perhaps for a subway system, or for you more technically-minded, a fiber optic cable connection. In the virtual world of computers world, however, tunneling refers to a protocol in which one protocol is encapsulated within another.

Tunneling protocols are often used for establishing various types of connections over common protocols, such as HTTP. For example, a peer-to-peer (P2P) file sharing program may mask data as HTTP to allow the data to be transferred through a firewall. Since most firewalls allow HTTP (port 80) connections, the connection would likely be allowed, since this is the same port that the Web uses. If the program used its own protocol and port number, the connection may be blocked.

Tunneling can also be used to establish secure connections through protocols that are typically not secure. For example, the point-to-point tunneling protocol (PPTP) establishes a secure connection over a standard PPP connection, and can used to create a virtual private network (or VPN) between two remote locations. PPTP allows a user to "tunnel" to another location with a secure password-protected connection using the standard or PPP protocol.

Tutorial

A computer tutorial is an interactive software program created as a learning tool. Tutorials help people learn new skills by using a step-by-step process that ensures the user is following along and comprehending the material. For example, a Web development tutorial may begin with instructions on how to create a basic Web page. This page might only include the words "Welcome to my website" on it and use the minimum HTML required in order for the page to load in a Web browser. Once the user is able to create a working Web page, the tutorial may explain how to add other features, such as styled text, table layouts, and images, to the page. Then the tutorial may provide instructions on how to publish the Web page to the Internet.

Some software tutorials provide testing features to ensure comprehension of the material, while others may be simple walkthroughs of a software program. Tutorials can be used for both school and business purposes and are written for basic, intermediate, and advanced users. Even smart computer programmers use tutorials. Most software development programs include a tutorial for creating a "Hello World!" program, which is the most basic program that can be created with the software. Since tutorials offer a gradual approach to learning, they can be helpful to people at many different skill levels. If a computer programmer can benefit from a tutorial, just about anybody can.

TWAIN

Other than being the last name of the author of "Huckleberry Finn," there are numerous other ideas concerning the origin of this term. Some believe it stands for "Toolkit Without An Informative Name," while others argue it is "Technology Without An Interesting Name." Still, there are some who believe that it came from the saying, "Ne'er the twain shall meet."

Though the real story behind the name may never be known, the purpose of TWAIN is quite clear. It is a graphics and imaging standard that allows companies to make drivers for scanners and digital cameras. Nearly all scanners on the market today are TWAIN-compliant, meaning the way they interact with your computer is based on the TWAIN standard. If you feel the need to know more about TWAIN and its fascinating history, the TWAIN Group has a website that you can visit.

Tweak

When you modify a certain piece of hardware for better performance, it is often referred to as "tweaking" it. Overclocking the computer's CPU or changing jumper settings on the motherboard are common examples of hardware tweaking. Removing system limitations and adding plug-ins or extensions to a computer's operating system are types of software tweaking.

Tweaking a computer is much like "tuning" a car (you know, the ones with the huge mufflers, big spoilers, and pimped out rims). It may increase performance, but is best left in the hands of the technically savvy. For example, overclocking your computer's processor may cause it to crash frequently, or worse yet, overheat and destroy the CPU. So, for most people, it is best to leave well enough alone.

Tweet

Example: "He stays connected to his friends by viewing their tweets on his Twitter home page."

A tweet is an update published by a Twitter user. It is similar to a blog posting, but cannot be longer than 140 characters. Tweets are meant to answer the question, "What are you doing?" which provides other users with quick updates about your life. When you publish a tweet, it will show up on the Twitter home pages of all the users you are following. Similarly, when you log in to Twitter, you will see the most recent tweets of the users that you have chosen to follow.

Twitter

Example: "She uses Twitter to follow the lives of her friends, as well as her favorite celebrities."

Twitter is a service that allows people to stay connected with each other by answering the basic question, "What are you doing?" Once you sign up for a Twitter account, you can post your own updates, or "tweets," using a computer or cell phone. You can also view the updates posted by other users you are following. Since each tweet is limited to 140 characters or less, the updates must be short and sweet. However, you may twitter as often as you want, meaning there is no limit on how much information you can share.

Typeface

A typeface is a set of characters of the same design. These characters include letters, numbers, punctuation marks, and symbols. Some popular typefaces include Arial, Helvetica, Times, and Verdana. While most computers come with a few dozen typefaces installed, there are thousands of typefaces available. Because they are vector-based (not bitmaps), typefaces can be scaled very large and still look sharp. The term "typeface" is often confused with "font," which is a specific size and style of a typeface. For example, Verdana is a typeface, while Verdana 10 pt bold is a font. It's a small difference, but is good to know.
