What are the two scripting categories
|
Client-side and Server-side
|
|
|
What is client side
|
code that is embedded into web pages.
The client browser software interprets and runs the script on the user's machine |
|
|
What is Server-side scripting
|
Scripts are stored, interpreted and run on the server. After the server processes the script, the resulting data is pulled onto the web page.
|
|
|
What is load distribution
|
Distributing the work load betwen the client and the server
|
|
|
What is Common Gateway Interface (CGI)
|
The standard many web servers utilize to connect to external programs or scripts
|
|
|
Where are CGI scripts are usually stored where?
|
CGI-BIN
|
|
|
List the pros of CGI
|
CGI is well tested
CGI can run on any operating system CGI uses interpreted languages-often scripting languages- that don't have to be compiled like programming languages Tons of scripts already exist |
|
|
List the cons of CGI
|
CGI has a higher risk of malfunction than some other methods
Each script runs as a separate process on the server CGI scripts reside in folders with execute permission Cgi scripts are stateless (cant tell the difference between one session and another) |
|
|
What language are CGI scripts usually written in
|
Perl Programming language
|
|
|
Users usually create Active Server pages (ASP) with what
|
VBSCRIPT
|
|
|
What are Active Server Pages files
extension |
.asp even though they often contain some regular (static) HTML content in addition to the ASP content
|
|
|
Developers don't use VBScript-ASP'S primary scripting language-for client-side scripting, why?
|
because it's not cross-browser compatible. As long as you use VBScript server-side and the server is configured to run it, only the server needs to understand it
|
|
|
What is Server-side JavaScript (SSJS)
|
The netscape equivalent of ASP
|
|
|
What is the database-connection part of SSJS
|
LIVEWARE
|
|
|
What is PHP
|
Personal Home Page an open source serve side scripting language
|
|
|
What is ColdFusion
|
a server-side scripting language originally created by Allaire
|
|
|
Who later purchased Coldfusion
|
Macromedia and now it's part of Macromedia's Dreamweaver Ultradev program
|
|
|
What is Coldfusion's scripting/markup language called
|
ColdFusion Markup Lnguage (CFML) and ends with the .cfm extension
|
|
|
When creating a form the method attribute can equal either GET or Post.
What does each do |
The "GET" Adds the form data to the end of the url string (the web page address up in the address bar)
The "POST" sends the form data as a separate text file. As a seperate file, it can be encrypted to keep the data secure. |
|
|
What are SERVER Application Programming Interfaces (SAPIs)
|
Web server extensions (preprogrammed bits of code ) that server administrators can download.
|
|
|
What is one benefit of SAPI over CGI
|
SAPI applications are threaded. This means that each part of the process runs as a subprocess, or miniprogram on its own. If the process is interrupted it can just start over where it stopped-each part runs independently
|
|
|
What is Internet Server Application Programming Interface (ISAPI)
|
The type of Server Application Programming Interface's that Microsoft servers use
|
|
|
What is the name of the shared library files that ISAPI'S use?
|
DLL (DYNAMIC Link Library)
|
|
|
What are DLL files
|
Files that can be shared and run by several programs at once
|
|
|
What are JavaServer Pages (JSP's)
|
The server-side equivalent of Java Applets
|
|
|
What is a Nonrelational database
|

|
What is object-oriented
|
A newer type of data-base which can be created with objected-oriented programmingh languages, such as Java or C++
|
|
|
What is Open Database Connectivity
|
The Microsoft method of connecting programming or scripting to a database
|
|
|
What is Java Dabase Connectivity (JDBC)
|
A database connection system developed by Sun Microsystems. It's platform independent unlike ODBC
|
|
|
What are the 3 parts to a database
|
User interface
Process logic Data storage |
|
|
Explain User Interface
|
The interface the user works with
|
|
|
Explain the Process logic
|
The part of the database program that processes and queries information.
SQL AND OQL ARE PART OF THE PROCESS LOGIC STEP |
|
|
What is data storage
|
The tables and/or fields where the data is stored
|
|
|
What is it called if the user interface, process logic and data storage are all contained on one machine
|
one-tier computing
|
|
|
What is two-tier
|
Database processes are spread over two computers; one takes care of the process logic and data storage, the other just formats the dat on the screen
|
|
|
What is three-tier computing
|
Three separate computers each handle one aspect of the database.
One-contains the user interface another -process logic the third - handles the data storage |
|
|
What is n-tier
|
The user interface and data storage are on two separate computers while the process logic (the most demanding) is spread over several computers
|
|
|
What is a thin-client
|
It implies the database functions are spread over at least three computers (a three-tier process)
|
|
|
What are the three parts to a packet
|
Header, Data and Trailer
|
|
|
What is the header of a packet
|
The part that contains addressing information

|
|
What is Demultiplexing
|
The procedure that the destination computer uses to process an incoming packet
|
