RTA 211: Production Theory // Dana Lee
Lecture 9:
Computers and CPTR Networks:
Microprocessor:
- Using its ALU Arithmetic Logic Unit, a
microprocessor can perform mathematical
operations
- It can move data from one memory location to
another
- A microprocessor can make decisions and jump
to a new set of instructions based on those
decisions
- And that's ALL IT CAN DO
RAM
- Random access memory (you can get at it and change its contents via the
microprocessor
ROM
- Read Only Memory (you can only read its contents via the microprocessor, not
write to them)
STORAGE:
- RAM will lose all its data if subjected to power loss
- Hard drives crash
- CD’s get scratched
- Moral: always make backups!
Ethernet
- Communication over a single cable shared by all devices
- Is a local area technology, with networks traditionally operating within a single
building, connecting devices in close proximity
- This is cold a Local or Wide Area Network
How Networks Work:
A protocol is a set of rules that govern communications - a language
Information is sent in a series of frames
These packets of information are sent
To be sent every frame sent must have both a destination address and a sending
address
