What is the Address Bus?
Holds the address of the area of memory from which information is to be read or written. Uni-directional, all lines of the address bus work together. Holds an address, never holds data.
Holds information to be read or written to memory. Bi-directional, all lines of the data bus work together. Data held may be an instruction, result of calculation, etc.
Lines work independently of each other. Each line has a specific function, examples are NMI, read, reset. Carries status and control information between CPU and devices. Direction depends on the function of the line.

Holds information to be read or written to memory. Bi-directional, all lines of the data bus work together. Data held may be an instruction, result of calculation, etc.
What is Polling?
A continuous method of checking other programs or devices by one program, or device to establish its state usually to see if they are still connected or want to communicate.
Is when a signal is received from a device attached to a computer or from a program within the computer that causes the main program that operates the computer to stop and work out what to do next.
What is Interrupts?
A continuous method of checking other programs or devices by one program, or device to establish its state usually to see if they are still connected or want to communicate.
Is when a signal is received from a device attached to a computer or from a program within the computer that causes the main program that operates the computer to stop and work out what to do next.
What is the Kernel
Heart of the system, provides access to the processor. Adopts scheduling policy and ensures interrupts and requests are sent to the correct part of the operating system
A peripheral device must have its own device driver which can be available via the O/S or supplied by a third party (normally the manufacturer or vendor of the hardware). Provide communication channel between device and O/S.
Allows users to interface with the system. Allows the user to issue instructions, interprets user commands and passes to appropriate part of the system and displays error messages.
Present a consistent view of file access across differing storage media. Allows programming without direct reference to the type of hardware or where the data is held.
Provision of storage facilities for large amounts of information and the mechanism for file access should be transparent to the user. Provide facilities for file protection and treat different file types in a standard way

What is the MAR Register?
Holds the address of the memory location being accessed
Holds the data that has been read or about to be written to memory
Holds the current instruction that is being executed
Holds the address of the next instruction to be executed
