TCP/IP review: when do you need to reset it?
TCP/IP is a Transmission Control Protocol/Internet Protocol. The TCP component lets you set a connection between two endpoints and specifies how the information is transferred and obtained. It also provides firm and trouble-free transfer of packets. The IP component is only associated with packets. To cut a long story short, TCP IP is a range of communication protocols applied to interconnect network appliances on the web.
TCP/IP Reset restores PC’s Internet Protocol parameters to default and often resolves connection troubles. Restoring these parameters is a routine work while attempting to fix “This Site Can’t be Reached” or “Unable to Connect to the Internet” or “Hmm… cannot reach this page” issues with error codes DNS_PROBE_FINISHED_NXDOMAIN or INET_E_RESOURCE_NOT_FOUND.
