What is Section Header and how to create? 
     If you are creating a new page and each page needs title and description, can be done by Section Header.

Code:

<apex:page >
    <apex:sectionHeader title="Section1" subtitle="Subtitle1" description="Description1" help="http://google.com" rendered="true"/>
</apex:page>

What is Global Data? how can we use it in VF pages in Salesforce?
     Global data is nothing but accessible in globally. we have many Global variables available in salesforce, refer the link to get all types of Global Variables.

https://help.salesforce.com/articleView?id=dev_understanding_global_variables.htm&language=en_US&type=0

Some Commonly used Global variables are
$User
$Label
$ObjectType
$Organization
$Permission
$Profile
$System
$UserRole

Code:

<apex:page controller="calAge">
    <apex:sectionHeader title="Section1" subtitle="Subtitle1" description="Description1" help="http://google.com" rendered="true"/>

    Lastname: <b>{!$User.LastName}</b> <br/>
    Organization: <b>{!$Organization.Name}</b> <br/>
    Profile: <b>{!$Profile.Name}</b>
    
</apex:page>

How to Parse Data from URL?
     {!$CurrentPage.Parameters.parameterName} is used to get Parameters from URL.
Example, Display Name, Age and Gender from URL in VF page.

Code:

<apex:page>
    <apex:sectionHeader title="Section1" subtitle="Subtitle1" description="Description1" help="http://google.com" rendered="true"/>

    Lastname: <b>{!$User.LastName}</b> <br/>
    Organization: <b>{!$Organization.Name}</b> <br/>
    Profile: <b>{!$Profile.Name}</b>
    
    Parameters from URL: -> {! $CurrentPage.Parameters.Name}, {! $CurrentPage.Parameters.Age}, {! $CurrentPage.Parameters.Gender}
    
</apex:page>

What is Controller in VF page?
     There are two type of controllers in the salesforce, named Standard Controller and Custom Controller.
Standard Controller    :-> StandardController = '<Standard Object Name>'
Custom Controller      :-> Controller = '<Apex class name>'
Extension                    :-> Extension = '<Apex class name>'

Example: Get account name, Note: can't get account name until id parameters parsed in URL.
URL?id=0014100000S6O0s

Code:

<apex:page StandardController="Account">
    <apex:sectionHeader title="Section1" subtitle="Subtitle1" description="Description1" help="http://google.com" rendered="true"/>

    Lastname: <b>{!$User.LastName}</b> <br/>
    Organization: <b>{!$Organization.Name}</b> <br/>
    Profile: <b>{!$Profile.Name}</b><br/><br/>
    
    Account name: {! Account.name}
        
</apex:page>

Example 2: Get list of Account names from Account object.
     It's time to use DataTable, if there are nay repetitive records or list of records, DataTable is required.

Output components are used to display the data, it works just like label in HTML.
OutputLabel  ->   Cannot Edit, Read only
OutputText    ->   Connot Edit, Read only
OutputField   ->   Can Edit, if used InlineEditing option.

Code:

<apex:page StandardController="Account">

    Lastname: <b>{!$User.LastName}</b> <br/>
    Organization: <b>{!$Organization.Name}</b> <br/>
    Profile: <b>{!$Profile.Name}</b><br/><br/>
    
    <apex:form >
        <apex:inlineEditSupport >
            <apex:outputLabel value="{!account.name}"/>   <br/>
            <apex:outputText value="{!account.name}"/>   <br/>
            <apex:outputField value="{!account.name}"/>   <br/>
        </apex:inlineEditSupport>
    </apex:form>
</apex:page>

What are Input components in VF pages? and example.

inputText     -> Used to Input text, irrespective to datatype
inputlabel    -> same as inutText, irrespective to datatype
inputField    -> Same as inputText, respective to Datatype
inputSecret  ->  Password type

     Used to select multiple/single (Ex: picklist/Radio/checkbox) value from list of options.
SelectList
SelectOption  -> Options in the picklist are created using this components
SelectOptions  -> When list of options are already available in List datatype.

          <apex:selectOptions value="{! Method1}"/>
        </apex:selectList>

    public List<SelectOption> getMethod1()
    {
        List<Account> lname = [Select name from account limit 10];
        List<SelectOption> ll = new List<SelectOption>();
        for(integer i=0;i<10;i++)
        {
            ll.add(new selectOption(String.valueOf(i),String.valueOf(lname[i].name)));

Example1:

Create a task for the opportunity owners who's opportunity is not closed even close date cross the close date.

Note: Schedule and Batch classes always should be Global.

global class RemindOpptyOwners implements Schedulable {

    global void execute(SchedulableContext ctx) {
        List<Opportunity> opptys = [SELECT Id, Name, OwnerId, CloseDate 
            FROM Opportunity 
            WHERE IsClosed = False AND 
            CloseDate < TODAY];
        // Create a task for each opportunity in the list
        TaskUtils.remindOwners(opptys);
    }
    
}

//Code from Salesforce.com - Trailhead

Note: TaskUtils.remindOwners(opptys); is creates a task for the owners.

Now, Autorun the jobs for every Monday at 2 am.

Schedule jobs run as -> Seconds Minutes Hours DaysOfMonth Month DayOfWeek Year

There are also some special characters you can use:

, used to delimit values [hours, day of month, month, day of week, year]
– used to specify a range [hours, day of month, month, day of week, year]
* used to specify all values [hours, day of month, month, day of week, year]
? used to specify no specific value [day of month, day of week]
/ used to specify increments [hours, day of month, month, day of week, year]
L used to specify the end of a range [day of month, day of week]
W used to specify the nearest weekday [day of month]

# used to specify the nth day of the month [day of week]

RemindOpptyOwners reminder = new RemindOpptyOwners();
// Seconds Minutes Hours Day_of_month Month Day_of_week optional_year
String sch = '0 30 8 10 2 ?';
String jobID = System.schedule('Remind Opp Owners', sch, reminder);
