Sip and lumsum difference

What is difference between investing a amount in lumsum of 1k or sip of 1k ?
Is both the way same ?

In Both you will have the same value of investment.

In lumsum you have made 1 time investment of 1k.
in SIP also you have made 1k investment and you need to give a particular date, for that date everymonth investment will be made with 1k each,
for this SIP in Zerodha you need to maintain this 1k everymonth on SIP date in the trading ledger.

In other MF distributors you need to maintain the balance in the mapped bank account, on SIP day funds will debit from the bank.
