Reference Materials and Glossary

RAM Alterable memory used for data storage and stacks.

Restart Procedure An AMX or application procedure executed by AMX during the

initialization phase when an AMX system is started.

ROM Read only memory of all types including PROMs, EPROMs and

EAROMs.

RTOS A short form for referencing a real-time operating system, usually

one with multitasking capability and reasonably good response to

rapidly occurring external events.

RT/OS The KwikNet syntax used to specify a general purpose operating

system. The term RT/OS is used to encompass both multitasking

and single threaded operating systems when the distinction is

irrelevant.

Semaphore A data structure which can be used by an RTOS to provide an

event signaling mechanism or mutually exclusive access by tasks

to specific resources.

Single threaded A method of program execution in which all procedures execute

sequentially. This method of operation is sometimes called single

tasking. Although interrupts can cause a brief digression in the

program's sequential operation, execution after an interrupt has

been serviced always resumes in the procedure which was

preempted by the interrupt.

SLIP Serial Line Internet Protocol: a simple network protocol used to

control the delivery of IP datagrams between two hosts

interconnected by a serial link.

SMTP Simple Mail Transfer Protocol: a TCP/IP protocol used to transfer

mail messages from one machine to another.

SNMP Simple Network Management Protocol: a protocol used to

monitor and manage the operation of a host computer and the

networks to which it is attached. Operations depend on the ability

to access and modify variables in the host's Management

Information Base (MIB).
