Fetch

PC = 0, value in PC copied to the MAR, MAR sends this through the address bus to the MDR, data bus sends to the CIR to be decoded. PC increments to 1.

What register changes in execute

PC

Pipelining

Allows for multiple instructions to be carried out concurrently through the use of overlapping Fetch, decode and execute cycles allowing for more processor efficiency

Types of memory addressing

Indirect, indexed, immediate, direct

Benefits of assembly language

compilation much quicker than higher level

larger RAM

Less virtual memory used, which is slower than RAM, quicker because while using VM it has to swap with data currently in RAM

SSD benifits

More durable small size

BIOS

Checks on all the hardware (POST test), Contains start up instructions.

Operating system roles

File management (deletes moves creates files), user interface (allows the user to interact with the computer)

Linker

a program that combines object code files into a single executable file

Loader

a program that loads an executable file into main memory

Best things on a client side

coding

Protocol

a set of rules for data transmission between devices

Hardware in LANs

WAP (wireless access point), Ethernet (wired access point)

Flat file

easy to set up, searching is slower

rational

easy to manage, difficult to set up
