linux shell patch commands

As i am new to linux, what is meaning of following scripts :- 

wget http://downloads.architechboards.com/deposit/microZed_wilink8.config -O .config

What I know is that it will download from http://downloads.architechboards.com/microZed_wilink8.config. But what I am not getting is what is meaning of -O .config.

What is patch -p1 < microZed_wilink8.patch and what it will do?

1) from man wget

The documents will not be written to the appropriate files, but all will be concatenated together and written to file.

2) from man patch

patch takes a patch file patchfile containing a difference listing produced by the diff program and applies those differences to one or more original files, producing patched versions.

and

-pnum or --strip=num

Strip the smallest prefix containing num leading slashes from each file name found in the patch file.
