welcome to my class

in this particular class we will talk

about different types of browsers

here we have an example of chrome

firefox

internet explorer conqueror opera

and safari web browsers

types of browsers there are three types

of browsers

first is text based

second is graphical based

and the third one is java enabled

browsers

the first one text based browsers

what is the meaning of text based

browser the text based browsers

have the capability to assess the web in

text mode only

the arrow keys on the keyboard are used

to navigate

the highlighted words on the screen and

enter key is pressed to follow the

link

text browsers are the client programs

which relates only to the

textual part of the information on the

web

it means if some information is

available in audio video graphics

then this browser is not able to handle

those things

if some information is in the text form

only then this browser is of

some use to us

example unix is popular text based

browser

advantages in general they are not used

by many people

however text based browsers offer

following advantages

the first one is feed these browsers can

load text pages very fast

no redundant information redundant means

useless

they serve the information without the

extra stuff

only the required information is brought

by these browsers

they do not carry any additional

information

the third advantage is handle image maps

some text browsers can handle only some

types of

image maps common feature

most of them have common features of

browser such as

bookmark and cookies

the second one is graphical browser

what is the meaning of graphical browser

the graphical browser allows

retrieval of text along with audio video

animation and skill pictures

mouse can be used to navigate the net by

pointing on the highlighted words and

graphics

example there are many graphical

browsers which run

on different kinds of computer systems

the most popular graphical browsers are

google chrome

netscape navigator and internet explorer

what are the advantages of graphical

browsers

they offer number of advantages

first complexly formatted tags

graphical browsers allow the user to see

more complexly formatted text

in different phone types size and colors

they allow viewing of videos graphics

and animation

and hearing of sounds as well

second help menu help many of these

browsers

enable its user to learn more about its

feature

and how to use them

use of pointing devices graphical

browsers also allow the use of

pointing devices like mouse to point

and click on selections on the screen

url address box url

is uniform resource locator it is the

official

address of the website

so these graphical browsers have an

address box

which shows the url of the webpage being

viewed by the

user

the browser will bring the webpage from

the web server and show it to the

user the moment user writes the address

on the address box

graphical web browser will copy that

address

and it will move on to that web server

for which that address is

it will retrieve the required web pages

from the web server and it will bring it

to the client machine

the third one is java enabled browser

pages of certain websites indicate that

they require

java enabled browser what is the meaning

of it

it means the website has something that

needs a java virtual machine

to be pre-installed on user system to

run smoothly

java language is the most powerful

language and is widely used

in the web application so the current

version of most of the web browsers

are made java enabled

example mostly used java enabled web

browsers

are internet explorer netscape

hot java firefox mozilla

etc

now what are the advantages of java

enabled browser

java enabled browser offers the

following advantages

first one dynamic data types java

language provides programmers with the

freedom to create

interactive content for the web by

developing new data types

and the methods to operate on them

pop-up feature java enabled browsers

allow pop-up ads

multimedia feature web pages can contain

audio video graphics and animations

platform independent java enabled

browsers are platform independent

in terms of computers and operating

system

it means you may be having any type of

hardware

any type of software these java enabled

browsers

they can work on different types of

machines

different types of hardware and software

it does not make any difference

in case of java enabled browsers

it means we may buy machine from any of

the computer manufacturers

or we may have any of the operating

system

java enabled browsers work on them

very smoothly

security java enabled browsers address

a significant concern regarding security

whenever files are being received from

an unknown or

untrusted sites
