### a mathematical model of a general computing machine

A Turing machine is a mathematical model of a general computing machine: a general computing machine is a theoretical device that manipulates symbols contained on a strip (on one or multiple tapes).

### an abstract representation of a computer

The Turing machine is an abstract representation of a computer; a computer essentially manipulates bits; if you're familiar with micro-processor design you'll see that the analogy holds very well.

### an abstract machine[1] that manipulates symbols on a strip of tape according to a table of rules

A Turing machine is an abstract machine[1] that manipulates symbols on a strip of tape according to a table of rules; to be more exact, rules is a mathematical model that defines such a device.[2]

### an idealised model of a central processing unit (CPU) that controls all data manipulation done by a computer, with the canonical machine using sequential memory to store data

A Turing machine is an idealised model of a central processing unit (CPU) that controls all data manipulation done by a computer, with the canonical machine using sequential memory to store data.

### a finite-state machine associated with a special kind of environment -- environment's tape -- in which its tape can store (and later recover) sequences of symbols'

A Turing machine is a finite-state machine associated with a special kind of environment -- environment's tape -- in which its tape can store (and later recover) sequences of symbols', also Stone 1972:8 where the word 'machine' is in quotation marks.
