Hi,
I bought new lap top, I need to connect my laptop to my Office PC , for data accessing, please give me a solution for connect this two device without interface...

When you say "without interface" I assume you mean a network.
Well in that case you can't.

You would need to either setup a home network or simply purchase a flash drive or USB hard drive and use that.

Do you mean you want to connect remotely or what?

Wireless?

Curlyben has an excellent suggestion. Use mobile storage such as a flash drive.

Many companies will also restrict access to the computer such that you will not have Administrator access. This would be required to setup a home type network. Also, to make it easier for you, they would need to be part of the same Workgroup. This also means that the company computer would have to be removed from the company network first. This also likely not possible either by company policy or by security restrictions.

In our company, access to the corporate network, either directly or by remote access is restricted to company owned computers. This is the best way to ensure the security and integrity of the company data.

Unless your company approves a VPN connection from your laptop to your office network, the portable storage device is really your best bet.
