Final Information:

Closed book, closed notes, you can have 2 sheets of papers with notes on them
(both sides if you wish, really won't matter much).  NOTES MUST BE
HAND-WRITTEN.

What you should know:

    All the stuff that you needed to know for the midterm (Chapters 1, 2, and
    Appendix.  You remember - boolean logic, error correction, carry-lookahead, 
    State Transistion Tables, implementing K-maps using FF's, etc.), plus:

    Chapter 3:  System Buses
	The Fetch-Decode-Execute Cycle
	Interrupts (what they are, why they matter, how they fit in)
	Interconnection Structures
	Bus interconnection, structures, types (Daisy chains, polling, etc)
	Communication types, timings (arbitration, sync, asynch, handshaking)

    Chapter 4:  Cache Memory
	Memory heirarchies (what they are, why they matter)
	Caches (what, why, how they work, replacement policies, block/line size,
	write policy, etc. etc. etc.)

    Chapter 5:  Internal Memories
	Physical Characteristics 
	Access types (serial, RAM, ROM, etc)
	Packaging
	Error Correction codes

    Chapter 6:  External Memory
	Magnetic Media (Disks, Tapes)
	    Heads, Tracks, Sectors, RAID, etc.
	Optical Media (CD-ROM, WORM, etc)
	    CAV, CLV, etc.

    Chapter 7:  I/O
	Types of I/O
	I/O Modules
	Programmed vs Interrupt-driven vs DMA, pros and cons of each approach
	I/O Channels/processors/devices  
	Serial communication (RS-232, modems, etc)

    Chapter 8:  OS support
	Need for OS, what it does, why it exists
	Motivation for Multiprogramming, what it needs to work
	Process scheduling, PCB
	Virtual Memory (How it works, paging, segmentation, TLB's, etc.)
