The architecture of Selenium RC is complicated because it uses an intermediate RC Server to speak with the browser. The RC Server is installed initially before running the test scripts and acts as mediator between your Selenium commands and your browser.
When we execute a test script in Selenium RC, the subsequent operations are performed internally.
• The server injects a JavaScript program referred to as Selenium Core into the browser.
• Subsequently, Selenium Core will start receiving the instructions (Selenium commands) from the RC Server.
• When all the instructions are received, Selenium Core will execute them as JavaScript commands.
• These JavaScript commands act as instructions to the browser.
• The browser will execute all of the instructions provided by Selenium Core and returns an overall summary to the Server. This overall summary acts because the outcome which is displayed on the user screen.

The architecture of Selenium WebDriver is easier as compared to Selenium RC.
The browser is controlled directly from OS (Operating System) level. the essential requirements to run a test script on WebDriver are:
• An IDE (Integrated Development Environment) with any of the supported programing language like Java, C#, etc.
• A Browser to execute the instructions generated by the test script.

2. Speed <<< This is H3

Selenium WebDriver performs faster than Selenium RC because it interacts directly with the browser without using any external proxy server. Selenium RC, on the opposite hand uses an intermediate RC Server to speak with the browser.
Execution of test scripts takes longer in Selenium RC than WebDriver, since it uses JavaScript commands as instructions to the browser.

3. Object Oriented <<< This is H3

Selenium WebDriver is only object-oriented API, whereas Selenium RC is a smaller amount object-oriented API.
WebDriver is entirely supported object-oriented programming languages like Java, C#, etc.

4. Testing Mobile Applications <<< This is H3

Selenium WebDriver supports OS (Operating System) for mobile applications like iOS, windows mobile and android. On the opposite hand, Selenium RC doesn’t support testing of mobile applications.

5. Browser Support <<< This is H3

Selenium WebDriver also supports headless HTMLUnit browser (Invisible Browser).
Note: HTMLUnit is an invisible browser which facilitates faster execution of tests because it involves no time in expecting page elements to load.
Selenium RC doesn’t support the headless HTMLUnit browser because it needs a true browser to figure with.

Table Insertion Example <<< Table Data example in heading 4 H4

Accessors are the selenium commands that examine the state of the appliance and store the leads to variables. they’re also wont to automatically generate Assertions.
Some of the foremost commonly used Accessors commands include:

Command/Syntax	Description
storeTitle (variableName)	This command gets the title of the present page.
storeText (locator, variableName)	This command gets the text of a component
storeValue (locator,variableName)	This command gets the (whitespace-trimmed) value of an input field.
storeTable (tableCellAddress, variableName)	This command gets the text from a cell of a table.
storeLocation (variableName)	This command gets the absolute URL of the present page.
storeElementIndex (locator, variableName)	This command gets the relative index of a component to its parent (starting from 0).
