I WANT TO CONNECT MY WORKPLACE PC FROM MY HOME PC AND VICE-VERSA. HOW can i do this plzz help me

Common protocols include ftp and ssh. ftp is fine if you just need to access your files.

Is the work computer behind a firewall? Just ping the IP from home to verify.

For the home computer, do you have a static IP or DHCP (from the ISP)? Most are DHCP, which means that the IP can change on different logins. This makes it difficult to connect to it from outside. To try it, turn on DMZ (in the router configuration) and try pinging from work.

Both your home and office PCs are using non-routable addresses. Such address will not pass through a switch, so they are not visible from the internet. It would not be possible to connect them over the Internet.

If you need to connect to your office PC, you need to get a valid Internet address for that network (so it will be "visible" on the Internet), and then (I would suggest) set up a VPN tunnel through your office firewall for your home PC to use to connect to the office PC.
