Hey @Naveed-Jameel just like ganache, hardhat comes with a list of accounts for your local development needs. Hardhat gives you 10 accounts/signers that you can work with. If you remember correctly, we normally add an accounts section under networks in our hardhat.config.js file. In this section, we can add as many accounts for eithers rinkeby, polygon, goerli, mainnet, or whatever chain we want to. However, for hardhat, we don't need to because hardhat adds these accounts for us in the background and we use getSigners() method to retrieve them. If you want to see these accounts, just run yarn hardhat node or npx hardhat node and you'll see them along with their private keys.

signer is the wallet/private key/account that either deploys the contract or interacts with the contract. In the context of hardhat, it could be the list of 20 accounts that you are given by hardhat that you can use

[owner,acc1,acc2,acc3]=ethers.getSigners()
contract=await ethers.getContract("MyContract",owner)
here what is meaning of second line mean why we write owner while getting contract?

[Naveed-Jameel]

contract=await ethers.getContract("MyContract");
contract=await ethers.getContractFactory("MyContract");
can you please also tell what is difference between these two lines

Here we get an instance of the contract MyContract and then we connect it with the account owner

contract=await ethers.getContract("MyContract"); contract=await ethers.getContractFactory("MyContract"); can you please also tell what is difference between these two lines

@Naveed-Jameel These just are two different methods of ethers that return the contract, just the difference is that getContractFactory provide other extra information along with the contract.
