CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Add the string tcp.window_size to view the TCP window size."

A block of code is set as follows:

//Or
udp[Offset:Bytes]

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "When you go to the configuration menu and choose Networking."
