WITH TIMING OR CHANGEABLE PROGRAMMING MEANS:
(under the class definition) Apparatus which is provided with control means for storing coded instructions or other data necessary to regulate operation of the separation apparatus or causing various operations to occur according to preset timing sequences or to last for predetermined durations (e.g., timer switches, etc.).

Typing a list of instructions into a computer which is then "read" by several layers of software into "machine code". This machine code is executed in the main processor, causing the machine to perform certain actions.
Originally, proggramming had to control the computer is a very concrete, physicial way, where your program could decide on many of the physical aspects of things (voltages, relays, switches). This has long since disappeared, with several layers of pre-existing software covering all hardware.
A program can be stored as a file and brought back to be executed later (a novel concept at one point - my original programs has to be typed each time you wanted to run them!) In memory, they consist of a a code portion and a storage/data portion.
As the computer reads each instruction (again using several layers of interpretation), it will control aspects of the computer (printer, display, hard drive) and can store the results in the data area. The data fed into the system can come from the user, the network, the disk, or other devices (attached weather devices, game controllers, etc) and the data spit out of the program can be in the form of graphics (games) or decisions made (business-focused programs).
Of course, this is all a rough generalization, but overall programming is the art/science of crafting these instructions to work exactly as you intended. This can be more difficult than many people realize, and all of us have seen the occasional "bug" (coined when a moth burned out an early computers' glowing tube-based memory!).

There are several different types. It began in the seventies in what was called basic . Imagin it as a very long algebra stringhere is an old example:
01 "Hello"
02 how are you?
03 goto 01 to get that program to execute you'd type run at the dos prompt. I know that seems stoneage now, but that's all programming was in the seventies, but through trial and error they were able to develop windows.

Very simple: Tell the computer what to do. Give instructions to computer. Well not very simple but you can do it.

it is some sort of problem solving and that is written using a computer language.
