Modem

Modulator, DEModulator. A device you connect to your computer and phone line that enables your computer to communicate with other computers through the phone system. Modems convert the computer's digital signals into analog waves that can be transmitted over standard voice telephone lines. Modem speeds are measured in bits per second (bps) or Kilobits (Kbps), or thousands of bits, per second.

N

Network

Two or more computers that are connected together to share resources such as hardware, data, and software. Most common are the local area network (LAN) and the wide area network (WAN).

O

ODBC Support

Object Database Connectivity (ODBC) support allows ODBC compliant applications to connect to an ODBC database and extract data without requiring that the user have programming skills. For example, Microsoft Excel, Microsoft Access, and mySQL are ODBC compliant applications. Using ODBC and mySQL a user can import data directly into an Excel spreadsheet once mySQL ODBC drivers have been installed on the user's computer.

OPEX or Opex (Operating expenditures)

An on-going cost for running a product, business, or system. Its counterpart, a capital expenditure (CAPEX), is the cost of developing or providing non-consumable parts for the product or system.

P

Data is generally transmitted within networks in the form of data packets. These packets contain the Header, the actual data (user data) and redundant data (CRC) for error correction on the receiving end.

Page

A document, or collection of information, available by way of the World Wide Web. To make information available over the WWW, you organize it into pages. A page may contain text, graphics, video, and/or sound files.

PC

Personal Computer. In recent years, the term 'PC' is used most often to describe personal computers based on an Intel or Intel-compatible microprocessor.

PERL

Practical Extraction and Report Language. Perl is a server-side, interpreted language that provides much of the web's interactivity.

PGP

Portal

PPC

Pay Per Click. - This is a marketing campaign that is specific to search engines where you pay to advertise on the right hand side of the search for key terms. e.g. When a customer types in a key word then our ad appears in the search. If the customer clicks the ad then we pay the search engine for 'referring' the customers to our site.

Propagation

The process of disseminating information throughout a system. Example 1 - After you register a new Internet domain name, the information is propagated across the Internet when local DNS servers update their databases from a central file. Note: Not all local DNS databases are updated with the same frequency (hourly, daily, every other day, etc.). Example 2 - Password changes often must be made on several different servers and will not complete propagation until all affected servers update their databases. Updating (rehashing) a given server's database is usually an automated process that is performed at specific intervals.

Protocol

A set of rules that regulate the way data is transmitted between computers over a network.
