mswsock.dll error fix

What is a DLL?

DLL (Dynamic Link Library) files contain computer code and resources that can be used by multiple programs at the same time. This uses less system memory and helps your computer system run more efficiently. DLL files give program developers the ability to reuse code to add features to several programs without the need to write new code for each program.

There are many programs that require DLL files to function properly so when one of them is damaged or missing it will cause program crashes and poor system performance.

What is mswsock.dll?

The mswsock.dll is a part of the Microsoft Windows Sockets 2.0 Service Provider and while not in a direct connection to WinSock it does contribute some to its functionality. This module provides services that are not offered by WinSock. The mswsock.dll file is an API (Application Programming Interface) that is responsible for providing the Internet Protocols for Windows. The file includes the LSP (Layered Service Provider) which operates between the users Windows environment and a WinSock application to secure the users internet access.

The LSP is an essential feature of the mswock.dll module. To access the internet the LSP makes use of the WinSock 2 APIs to put itself into the TCP/IP (Transmission Control Protocol/Internet Protocol) stack. It also deals with the TCP/IP traffic between the Internet and the programs that are making use of the Internet.

The slight difference between mswsock.dll and winsock.dll lies in the available functions for each DLL. While the winsock.dll module with its main application define how a network software should access the TCP/IP network the mswsock.dll provides internet access for Windows.
