Hi Sai Tarun,

By default it shows the 20 records at a time.
You have to add the pagination in the page like below. 
<apex:page standardController="Account" recordSetVar="accounts" sidebar="false">
     <apex:form >
        <apex:pageBlock >
           <apex:pageMessages />
           
            <apex:pageBlockButtons >
               <apex:commandButton value="Save" action="{!save}"/>
               <apex:commandButton value="Return" action="{!cancel}"/>
            </apex:pageBlockButtons>
            

            <apex:pageBlockTable value="{!accounts}" var="acc" id="table">



               <apex:column headerValue="Account Name">
                  <apex:inputField value="{!acc.Name}"/>
               </apex:column>


              <apex:column headerValue="Website">
                 <apex:inputField value="{!acc.Website}"/>
               </apex:column>




              <apex:column headerValue="Account Site">
                  <apex:inputField value="{!acc.Site}"/>
               </apex:column>


               <apex:column headerValue="Fax">
                  <apex:inputField value="{!acc.Fax}"/>
               </apex:column>

           </apex:pageBlockTable>
           
           
           <apex:commandLink action="{!Previous}" value="Previous Page" rendered="{!HasPrevious}"/>
           <apex:commandLink action="{!Next}" value="Next Page" rendered="{!HasNext}"/>
           
         </apex:pageBlock>
      </apex:form>
 </apex:page>



I suggest you to go this book Visualforce In Practice - Chapter 4 (https://developerforce.com/guides/Visualforce_in_Practice.pdf) which has a lot of details on Standard Set Controller and recordSetVar along with how you can implement pagination, filterting, mass updates, etc..

Hi Sai Tarun,

Yes you can do this with the help of recordSetVar comonent  in custom visual force page.
  
<apex:page standardController="Account" recordSetVar="accounts" sidebar="false">
     <apex:form >
        <apex:pageBlock >
           <apex:pageMessages />
           
            <apex:pageBlockButtons >
               <apex:commandButton value="Save" action="{!save}"/>
               <apex:commandButton value="Return" action="{!cancel}"/>
            </apex:pageBlockButtons>
            

            <apex:pageBlockTable value="{!accounts}" var="acc" id="table">

               <apex:column headerValue="Account Name">
                  <apex:inputField value="{!acc.Name}"/>
               </apex:column>


              <apex:column headerValue="Website">
                 <apex:inputField value="{!acc.Website}"/>
               </apex:column>

              <apex:column headerValue="Account Site">
                  <apex:inputField value="{!acc.Site}"/>
               </apex:column>


               <apex:column headerValue="Fax">
                  <apex:inputField value="{!acc.Fax}"/>
               </apex:column>

           </apex:pageBlockTable>
         </apex:pageBlock>
      </apex:form>
 </apex:page>

Please check you accounts record and tab visibility in your org.
Also give your profile to Account edit,delete and view all permission if not.
Let me know for more help in this regard.
