NAK --- NCSA

 

NAK --- Negative Acknowledgement --- When a modem receives a data packet, it sends back a signal to the sending modem: either an NACK signaling all is well, or a NAK if some of the data is missing or corrupt. This negative acknowledgement acts as a request to resend the data.

NavEx --- A Windows 95 program that converts Netscape Navigator bookmark files into Microsoft Internet Explorer shortcuts. This program will also take a Windows folder containing your favorite URLs and convert it into a Netscape bookmark file which you can load into Navigator by opening the "GO TO BOOKMARKS" window and choosing FILE and then OPEN.

Navigate --- To move around on the World Wide Web by following hypertext paths from document to document on different computers.

Navigator (Netscape) --- The dominating World Wide Web browser. The program also allows for Gopher, FTP, and Telnet access as well as e-mail and newsgroup retrieval and management. Many companies use Netscape server software to create Web pages and are therefore written to be best displayed using Netscape Navigator. The program is available for all platforms and is also the smoothest and fastest when it comes to displaying graphics.

NCSA --- National Center for Supercomputing Applications --- has evolved into a scientific research center built around a national services facility. NCSA is developing and implementing a national strategy to create, use, and transfer advanced computing and communication tools and information technologies. These advances serve the center's diverse set of constituencies in the areas of science, engineering, education, and business. The NCSA is responsible for the development of the Mosaic World Wide Web browser.

Netscape --- A WWW Browser and the name of a company. The Netscape (tm) browser was originally based on the Mosaic program developed at the National Center for Supercomputing Applications (NCSA).

Netscape has grown in features rapidly and is widely recognized as the best and most popular web browser. Netscape corporation also produces web server software.

Netscape provided major improvements in speed and interface over other browsers, and has also engendered debate by creating new elements for the HTML language used by Web pages -- but the Netscape extensions to HTML are not universally supported.

The main author of Netscape, Mark Andreessen, was hired away from the NCSA by Jim Clark, and they founded a company called Mosaic Communications and soon changed the name to Netscape Communications Corporation.

Netscape color palette --- Network Interface card (NIC)

 
Netscape color palette --- Refers to the array of colors (approx 253) that are supported or can be correctly interpreted by the Netscape Navigator browser. These colors are supposed to be the standard colors that users with the "lowest common denominator" computer equipment will correctly see. Whether you have a 16 million color video card or a 256 video card in your computer, these colors are supposed to render the same way on both. These colors are also supported by Microsoft Internet Explorer, although some of them may deviate slightly.

The colors are set by a Web page author using the RGB (RedGreenBlue) hexidecimal value of the color. An example of the HTML syntax for setting color for a Web page looks something like this:
<body bgcolor="FFFFFF" text="000000" link="FF0000" vlink="00FF00" alink="FFFFFF">
The above syntax when placed in an HTML document would render the page with a white background, black text, red links, green visited links, and an active link color of white.

NetWare --- A trademarked brand name for the networking operating systems and other networking products developed and sold by Novell.

Netware Core Protocol (NCP) --- A NetWare protocol that provides transport, session, and presentation layer functions equivalent to layers 4,5, and 6 of the OSI model.

Netwatcher --- A tool included with the Windows 95. Net Watcher allows you to monitor and manage network connections, as well as create, add, and delete shared resources.

Network --- A group of computers connected by a communications link that enables any device to interact with any other on the network. The "network" is derived from the term "network architecture" to describe an entire system of hosts, workstations, terminals, and other devices.

Network Interface card (NIC) --- Also called a network adapter, an NIC is an interface card placed in the bus of a computer (or other LAN device) to interface to a LAN. Each NIC represents a node, which is a source and destination for LAN frames, which in turn carry data between the NICs on the LAN.

NOmepage --- A homepage with little or no content -- perhaps an image of the person's pet and a few links to their favorite tv show,but nothing original and not much of anything else.

NOn-volatile RAM --- RAM memory on a card that is not erased when power is cut off. Cards that don't use jumpers often store their resource requirements (IRQ, I/O Base address, I/O port, DMA channel, etc.) in non-volatile RAM. Non-volatile RAM is not normally used on a card that is compliant with Plug and Play, but was common on "legacy" (pre Plug and Play) cards.

NOn-Windows program --- A program not designed to be used specifically in Windows. Most non-Windows applications or programs are character-based in nature (for example, DOS programs).

NSF --- Null modem cable

 
NSF --- National Science Foundation --- An Independent agency of the Federal government that was established in 1950 by an Act of Congress. The agency's mission is to promote the progress of science and engineering.

NT-1 --- Network Terminator 1 --- An NT-1 is an interface box that converts ISDN data into something a PC can understand (and vice versa). It works a little like a cable TV descrambler for ISDN signals, and is often built in to ISDN adapters.

Null modem cable --- A serial cable link between computers. Standard modem software is often used to transmit information, but because there are no actual modems in the connection, very high transfer rates with good accuracy are possible. The cable must be different from a regular serial cable, however, because several of the wires in the cable must be cross connected to simulate the modem's role in acknowledging a transmission.
