What's the difference between the CGI and the FastCGI interfaces?

Aprelium Technologies - FAQ
Starting from version 2.3, Abyss Web Server features support for applications and interpreters conforming to the FastCGI specification. A FastCGI application or interpreter is loaded when needed by the web server, it executes a script, and sends its output back to the server. But instead of having its process automatically unloaded from the system as with CGI, it remains in sleeping state waiting for another request from the web server.

What's the difference between the FastCGI and the ISAPI interfaces?

Aprelium Technologies - FAQ
FastCGI interpreters and applications deliver performances comparable to (if not better than) their ISAPI extensions counterparts. Because they run in another process, they cannot affect the server and crash it if they have problems. This makes their use not prone to stability problems ISAPI extensions may cause.

What's the difference between the CGI and the ISAPI interfaces?

Aprelium Technologies - FAQ
Starting from version 2.0, Abyss Web Server supports dynamic documents generation through ISAPI extensions (besides the classical CGI applications interface.) ISAPI extensions are loaded on-demand and become resident in the server process space. This enhances significantly the performance as an extension is only loaded once and does not require any communication overhead with the server.

What is the difference between provider and admin interfaces ?

X-Cart: Frequently asked questions
There are three different interfaces: the first is the customer interface (the shop), the second is the provider interface and the third is the admin interface. Admin interface is created for shop owners. The admin interface can be used to configure and control the store. Unlike the admin interface, provider interface can be accessed by several _different_ product providers. Each of them can add/modify/delete their own products and keep track of their own orders.

Do CGI/FastCGI/PHP scripts execute under my own UID?

Csoft.net - Frequently Asked Questions
Yes. All CGI and FastCGI applications (including PHP scripts) will execute with your own unix account privileges. To save on resources, many inexpensive shared hosting providers will execute PHP scripts under a single account shared by all users of the system (thus requiring users to open up their script data and databases to unauthorized access and intellectual property theft by other users on the same system). On our systems, all web applications will execute under your own unix privileges.

Why isn't FastCGI included with Apache any more?

Apache Server Frequently Asked Questions
The simple answer is that it was becoming too difficult to keep the version being included with Apache synchronized with the master copy at the FastCGI web site. When a new version of Apache was released, the version of the FastCGI module included with it would soon be out of date.

What's the difference between hosts, gateways and interfaces?

Check Point Technical Support
In defining network objects, it is important to keep in mind the distinction between hosts, gateways, and interfaces. A gateway will have more than one interface, but the gateway itself is a single object and should be defined as such. Each of the interfaces is defined as a separate item in the Network Interfaces section of the Workstation Properties window. A host's name is the string returned by the hostname command.

What Is the Difference Between Using Generics and Using Interfaces (or Abstract Classes)?

Generics FAQ: Fundamentals
Interfaces and generics serve different purposes. Interfaces are about defining a contract between a service consumer and a service provider. As long as the consumer programs strictly against the interface (and not a particular implementation of it), it can use any other service provider that supports the same interface. This allows switching service providers without affecting (or with minimum effect on) the client's code.

What is the difference between public and private interfaces?

Frequently Asked Questions — CellML
interface in CellML is a component's door to any other component. An interface can be public or private. In CellML a private interface only occurs between a parent component and its encapsulated child. A parent component will send and receive variables through a private interface to and from the encapsulated component. However, the encapsulated child will send and receive variables to and from its parent component through a public interface.

What is the difference between keyboard wedge and RS-232 interfaces?

CHAMP - SUPPORT/DRIVERS - Barcode FAQs
For a keyboard wedge interface, the scanner or reader (decoder built in) connects to the keyboard port of computer, the keybard will connect to the split cable of scanner and remains fully functional. The data scanned from a bar code symbol is treated as it is typed in from the keyboard. For RS-232 interface, the scanner or reader connects to a serial port and transmits serial data to the host machine. The host must be set up to receive serial data.

What is the difference between the Secure and the Non-Secure interfaces?

ESQ
There is no significant difference between the two interfaces excepting the fact that, Secure interfaces establish connections using services provided by TME 10 Framework and Non-Secure interfaces establish connections using standard inter-process communication mechanisms. There is however no compromise in terms of system security when a Non-Secure interface is used.

CGI Script is a programming language that a web server uses Without seeing the messages, I cannot be sure what they are. One possibility is that they are binary files (pictures, executables, spreadsheets, etc.). Newsgroups are collections of text files. There are techniques for "encoding" binary files into a text format that can be handled by newsgroups. This technique is called uuencode/uudecode.

The Common Gateway Interface, or CGI, is a standard for external gateway programs to interface with information servers such as HTTP servers. A plain HTML document that the Web daemon retrieves is static, which means it exists in a constant state: a text file that doesn't change. A CGI program, on the other hand, is executed in real-time, so that it can output dynamic information.
