SOA (Service Oriented Architecture) - When businesses grow, they often add new products and services. While these additions may help make the business larger, it is often difficult to implement them in an efficient manner. The goal of SOA is to make it easy for businesses to grow and add new services.
Meta Search Engine - Meta search engines are search engines that search other search engines. Confused? To put it simply, a meta search engine submits your query to several other search engines and returns a summary of the results. Therefore, the search results you receive are an aggregate result of multiple searches.
Meta Tag - This is a special HTML tag that is used to store information about a Web page but is not displayed in a Web browser. For example, meta tags provide information such as what program was used to create the page, a description of the page, and keywords that are relevant to the page. Many search engines use the information stored in meta tags when they index Web pages.
Spider - A spider is a software program that travels the Web (hence the name "spider"), locating and indexing websites for search engines. All the major search engines, such as Google and Yahoo!, use spiders to build and update their indexes. These programs constantly browse the Web, traveling from one hyperlink to another.
SSH (Secure Shell) - is a method of securely communicating with another computer. The "secure" part of the name means that all data sent via an SSH connection is encrypted. This means if a third party tries to intercept the information being transferred, it would appear scrambled and unreadable. The "shell" part of the name means SSH is based on a Unix shell, which is a program that interprets commands entered by a user.
