source route      
<messaging> An electronic mail address which specifies the route the message should take as a sequence of hostnames. It is called a source route because the route is determined at the source of the message rather than at each stage as is now more common. The most common kind of source route is a UUCP style bang path, "foo!bar!baz!fred'. The RFC 822 syntax, "@foo:@bar:fred@baz", is seldom seen because most systems which understand RFC 822 also perform automatic routing based on the destination hostname. A third, intermediate, form is sometimes seen: "fred%baz%bar@foo.com".

IP Source Routing
In computer networking, source routing, also called path addressing, allows a sender of a packet to partially or completely specify the route the packet takes through the network. In contrast, in conventional routing, routers in the network determine the path incrementally based on the packet's destination.

Source code

In computing, source code, or simply code, is any collection of text, with or without comments, written using a human-readable programming language, usually as plain text. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code.

The source code is often transformed by an assembler or compiler into binary machine code that can be executed by the computer. The machine code is then available for execution at a later time.

Most application software is distributed in a form that includes only executable files. If the source code were included it would be useful to a user, programmer or a system administrator, any of whom might wish to study or modify the program.

Alternatively, depending on the technology being used, source code may be interpreted and executed directly.
