I and J of Digital Media - iMac and Java
Image Capture
Image Capture is an application program that enables users to upload pictures from digital cameras or scanners which are either connected directly to the computer or the network. It provides no organizational tools like iPhoto but is useful for collating pictures from a variety of sources with no need for drivers. It achieves this by “receiving the picture” as it is and through a conversion process, downloads it onto your computer. It uses QuickTime Image Capture[1]. This way it doesn’t need to understand anything about the actual camera to be able to do that. It was first introduced in Mac OS X version 10.0 (Cheetah)
Image Capture is scriptable with Applescript, and may be manipulated with Mac OS X v10.4 (Tiger)’s “Automator” application. As of Mac OS X 10.4, Image Capture’s AppleScript dictionary does not open in Script Editor.
iMac (from Wikipedia)
The iMac is a desktop Macintosh computer designed and built by Apple Inc. It has been a large part of Apple’s consumer desktop offerings since its introduction in 1998, and has evolved through three distinct forms. In its original form, the G3, the iMac was gum drop or egg shaped with a CRT monitor, mainly enclosed by coloured, translucent plastic. The second major revision, the G4, moved to a design of a hemispherical base containing all the main components and an LCD monitor on a freely-moving arm attached to the top of the base. The iMac G5 and the Intel iMac placed all the components immediately behind the monitor, creating a slim design which tilts only up and down on a simple metal base. The current iMac shares the same form as the previous models, but is now thinner and uses brushed aluminum and black-bordered glass for its case.
Like other Apple products, the iMac enjoys a relatively high profile in popular culture due to its distinctive aesthetics and Apple’s successful marketing. The iMac and other Macintosh computers can also be seen in various movies, commercials, and TV shows (both live action and animated).The iMac has also received considerable critical acclaim, including praise from technology columnist Walt Mossberg as the “Gold Standard of desktop computing”;Forbes Magazine described the original candy-colored line of iMac computers as being an “industry-altering success”. The original 24″ Core 2 Duo iMac received CNET’s “Must-have desktop” in their 2006 Top 10 Holiday Gift Picks.
PS: I have to say that after spending some time with iMacs of late - I am going to actually buy one myself 
iTunes
iTunes is Apple’s own digital media player application and it is compatible for PC as well. You don’t have to have an iPod to use iTunes, but it is the best tool if you do have an iPod and want to manage the content on your iPod. I am almost ashamed to admit I have two iPods, one a video ipod and an older iPod Mini - and I don’t know what I would do without iTunes to manage my playlists!!
Internet
The Internet is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a “network of networks” that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked web pages and other resources of the World Wide Web (WWW).
Index Page
An index page is configured on web servers (microsoft iis, apache etc) to return the desired page filename (eg; index.htm, default.asp, index.sthml etc) when the user requests a folder path and not a specified filename. For example if a user requests http://www.site.com/myfolder/ the web server will return the configured index page eg; http://www.site.com/myfolder/index.html
ISDN (Integrated Services Digital Network)
From kb.iu.edu. Integrated Services Digital Network (ISDN) is fully digital telephone service, providing data, voice, and video channels over the existing phone network. While most of the current phone network is already digital, ISDN replaces the final analog section connecting the local exchange with individual houses or offices to create a fully digital connection.
Not only is ISDN much faster than a standard analog telephone connection, but also its multiple channels allow you to use several devices (such as a telephone, computer, and fax) simultaneously on the same line.
You usually obtain ISDN service from a telephone company and Internet service provider. There are two different classes of ISDN: Basic Rate Interface (BRI) and Primary Rate Interface (PRI).
Basic ISDN (BRI) is designed to meet the needs of most individual users and small networks. It is fairly inexpensive and can use existing phone wiring. It divides the telephone line into three channels: two 64Kbps bearer channels (B channels) and one 16Kbps D channel for setting up and managing calls. In some situations, the two bearer channels can function together as a single virtual channel, with a data transmission speed of 128Kbps.
PRI ISDN is designed for organizations with greater capacity requirements. It uses a full T1 line, transmitting at 1.544Mbps. It offers 23 B channels at 64Kbps, and one 64Kbps D (setup) channel.
Using ISDN service requires an NT-1 terminator to connect with the phone company’s lines, and a terminal adapter (sometimes imprecisely called an “ISDN modem”) to connect to the computer. Some adapters have integrated NT-1s. Connecting several networked computers to the ISDN line involves using an ISDN router to connect to your hub. Some ISDN routers incorporate NT-1s and/or hubs.
ISP (Internet Service Provider)
An ISP (Internet Service Provider) is a company that collects a monthly or yearly fee in exchange for providing the subscriber with Internet access.
An ISP might provide dial-up service, cable, DSL, or other types of Internet access. Some ISPs are local while others are national. A national ISP will provide access throughout most of the nation, while a local ISP will only serve subscribers in a limited geographical region.
When looking for an ISP the initial consideration is the type of access desired. Some ISPs only offer dial-up access which is the slowest type of connection. If you want cable service, you’ll be checking with your local cable TV provider to see if cable access is offered. For DSL service, you may have multiple choices - or it could be that DSL is not yet available in your area. Often this can be remedied with a call to the phone company to upgrade local telephone lines.
Every ISP has a privacy policy and Terms of Service (TOS) contract that subscribers must agree to before subscription will be accepted. The privacy policy will state what the company will and will not do with personal information collected at the time of sign-up. Name, address, and normally a credit card number are required. The privacy policy should also state under what conditions your personal information might be shared with third parties, government officials, or others. The TOS contract stipulates how you can use the service. For example, dial-up access is often sold as “unlimited access” but this is not to be taken literally. Dial-up accounts normally limit hours per month to 250-400, depending on the ISP. Truly unlimited access (leaving your computer on and actively connected to the Internet 24/7) is called dedicated access. Most DSL or cable subscriptions allow dedicated access.
IP Address
An IP address (or Internet Protocol address) is a unique address that certain electronic devices use in order to identify and communicate with each other on a computer network utilizing the Internet Protocol standard (IP)—in simpler terms, a computer address. Any participating network device—including routers, switches, computers, infrastructure servers (e.g., NTP, DNS, DHCP, SNMP, etc.), printers, Internet fax machines, and some telephones—can have its own address that is unique within the scope of the specific network. Some IP addresses are intended to be unique within the scope of the global Internet, while others need to be unique only within the scope of an enterprise.
The IP address acts as a locator for one IP device to find another and interact with it. It is not intended, however, to act as an identifier that always uniquely identifies a particular device. In current practice, an IP address is not always a unique identifier, due to technologies such as dynamic assignment and network address translation.
Image Map
Thanks to about.com for this great explanation!
An image map is a graphic object that has many hotspots or invisible hyperlinks to other objects or websites. For example - in a photograph showing a variety of women’s clothing, if you clicked on the dress, you would be sent to another Web page or Web site containing all the info about the dresses; when you licked on the hat, you would be sent to the Web page or Web site about hats … and so on.
Javascript
Javascript is a scripting language developed by Netscape to enable Web authors to design interactive sites. Although it shares many of the features and structures of the full Java language, it was developed independently. Javascript can interact with HTML source code, enabling Web authors to spice up their sites with dynamic content. JavaScript is endorsed by a number of software companies and is an open language that anyone can use without purchasing a license. It is supported by recent browsers from Netscape and Microsoft, though Internet Explorer supports only a subset, which Microsoft calls Jscript.
JPEG File
Short for Joint Photographic Experts Group, and pronounced jay-peg. JPEG is a lossy compression technique for colour images. Although it can reduce files sizes to about 5% of their normal size, some detail is lost in the compression.
Java Applets
A Java applet is an applet delivered in the form of Java bytecode. Java applets can run in a Web browser using a Java Virtual Machine (JVM), or in Sun’s AppletViewer, a stand-alone tool for testing applets. Java applets were introduced in the first version of the Java language in 1995. Java applets are usually written in the Java programming language but they can also be written in other languages that compile to Java bytecode such as Jython.
Applets are used to provide interactive features to web applications that cannot be provided by HTML. Since Java’s bytecode is platform independent, Java applets can be executed by browsers for many platforms, including Windows, Unix, Mac OS and Linux.There are open source tools like applet2app which can be used to convert an applet to a stand alone Java application/windows executable/linux executable. This has the advantage of running a Java applet in offline mode without the need for internet browser software.
Juxtapose
Juxtapose is to place close together or side by side, esp. for comparison or contrast.
