A process is an independent program, which can execute and perform a task. It can have number of threads performing sub task as well. For example when we open Microsoft word it start a new process. And when we perform task in it for example Grammar check, font change, paragraph rephrase is done by separate threads under a parent process.

Service is a program/functionality exposed through interface. And the client can consume this service by adding service reference and implementing the methods in it. For example a service which perform the basic calculation operations like Addition, Subtraction, and Division etc can be exposed and client can consume it without having to write a new programs for it again.

To give another example for service,

MySql or particularly any database starts a service (at startup also) and we can use that service in our programs to do database operations. Unless the service is up, we will not be able to run any JDBC connection required program.
