Briefly describe the interface between the memory and the processing unit. That is, describe the method by which the memory and the processing unit communicate.

Research data that is presented using descriptive language is said to be

Which of the following statements is incorrect in relation to processes: while, strictly speaking, at any instant of time, the cpu is running only one process, in the course of 1 second, it may work on several of them, giving the illusion of parallelism a process is just an instance of an executing program, including the current values of the program counter, registers, and variables processes can be created when an operating system is booted, created by the user, or a running process can create children processes there is a master process, which when started can last forever, and is not killable

Part d: float check string has a method s.isdigit() that returns true if string s contains only digits and false otherwise, i.e. s is a string that represents an integer. write a function named float_check that takes one parameter that is a string and returns true if the string represents a float and false otherwise. for the purpose of this function we define a float to be a string of digits that has at most one decimal point. note that under this definition an integer argument will return true. remember “edge cases” such as “45.” or “.45”; both should return true. for example: float_check('1234') returns true float_check('123.45') returns true float_check('123.45.67') returns false float_check('34e46') returns false float_check('.45') returns true float_check('45.') returns true float_check('45..') returns false
