1. Server side scripting is used in website design and
involves embedding scripts in HTML code which
results in a client request to the server being handled
by the script.
When the users request is fulfilled the script is run on
the web server to create dynamic web pages.
Server side scripting is useful when websites need to
be interactive and respond with a database
Some benefits of server side scripting are:
Doesn’t require plugins to be downloaded
Templates can be used for an entire site
Load times are faster but can be dependant on server
Scripts are hidden from view, even if viewing source
2. Client side scripting is where the client has all the
process’s being performed on the client
computer
The web server will send the files on request to
the users web browser which executes the script
and displays the document
Examples:
Compiling will be done on the computer
Communications between the browser and the
application
JavaScript is purely client side but there is a
derision for server side
3. • PHP is a server side scripting language which is used primarily for
web development, PHP can be used alongside HTML making it a more
adaptable language than some
• Ruby is a dynamic, reflective, object-oriented, general purpose
programming language, this means that it can be used in a variety of
software development applications and as its dynamic and reflective
it offers extra features during runtime compared to static
programming
• Python is a general purpose programming language which means it
can be used for a variety of software applications such as web server
scripting or creating applications and forms.
4. Server side JavaScript is a derivation of
standard JavaScript language and there are
many implementations of it
ASP.NET is an open source server side web
application framework released alongside
version 1 of .NET framework. ASP.NET allows
for more dynamic web pages to be created
5. Some of the main functions of server side
scripting is for use in websites like amazon or
eBay for processing shopping carts where the site
has to respond to a database every time an order
is placed or an item is put in a basket
Also forms on websites will be stored on servers
because as they need to collect personal data,
server side scripts are more secure and therefore
can process and store the data securely in a
database
Because client side scripting can not
communicate with a database, websites where
there is a large stock held in a database need
server side scripts.
6. In server side scripting there is use of “cookies”
When you go on a site and use a form to login, such
as Amazon, Facebook, Google+ or any other account
held website your data is collected by the server
scripts into a cookie.
Each user has their own cookie which is only active
while the user is logged in and scrolling through
pages
A cookie works by remembering user data and then
recognizing the same user from their data every time
they open a new page on the same web site
As soon as you log out or close the web site down the
cookie gets deleted and removed from the server
The next time you login a new cookie will be created.
7. Can communicate with a database
Can allow for dynamic websites
The server deals with all server side languages and
then produces pure HTML for the client side
Usually faster loading times as no downloaded plug
ins are needed (flash, shockwave etc.)
For most websites that sell anything such as Amazon,
Game etc… they need a server side script to retrieve
data from a database and client side cant do this
Application can be stored in libraries on servers
which allows for developers to copy code and this
reduces the cost and time of developing new
programs
8. Scripting software needs to be installed on a
dedicated server
Most often a database or series of databases
are required for the scripts to function
properly
The dynamic scripts have security issues and
hackers can gain access to the server through
flaws in the code
Increase overheads from server having to
respond to many requests could slow down
or crash server
9. Interpreted language is where the language has not been compiled
for the machine and the server will take the code directly and
perform process's
When using server side scripting dependent on the amount of
software being used in the server will largely affect the overhead,
because if a user is purely using server side scripting to access web
pages the server will be doing all the work and therefore the
overhead is increased on the server but reduced for the client
If the server is hosting all the scripts and there are too many
requests it could cause slow speed, server crash’s or a corruption
The same goes for client side overheads when client side scripting is
being used the clients computer is performing all the tasks and this
will increase the overhead so if used in conjunction with server side
the overheads should be reduced on both sides
10. Server side scripting allows for much greater
scope at making websites more tailored to
individual needs.
By logging user data on a server and keeping
it stored in a database the server can
automatically determine which adverts to
show and which products or services the user
is most likely to want
The webpage can be adapted for user
requirements such as easier to read or make
the webpage more personal
11. Using both client and server side together will
reduce the overhead for both server and
client which should improve overall
performance and browsing speed
Websites such as Google, Amazon, Facebook
or Twitter will use both types of scripting
12. Server side will handle logging in, registration
forms, personal data, preferences and user
requirements and will provide the specific
data to the client after retrieving it from a
database.
Client side makes websites more interactive
and displays or sorts the data in different
ways dependent on the users actions such as
clicking on buttons or links
13. Because client side is less secure the
combination of both server and client side is
hugely beneficial for large websites such as
Amazon or eBay who have huge databases of
personal data that needs to be kept secure
Therefore having a secure dedicated server
keeps the data more secure and less likely to
be hacked
