Слайд 6What does memory look like?
Memory ~ RAM
Looks like a table
Address and
Data
Address is the location
Data is the actual value
Memory stores both data and assembly instructions

Слайд 7Central Processing Unit (CPU)
Also called the “chip” or “processor”
The brain of
the computer
Major components:
Arithmetic Logic Unit (ALU)
calculator
Control unit
controls the calculator
Communication bus systems

Слайд 8Fetch-Execute Cycle
Fetch instruction from memory
Decode instruction in control unit
Execute instruction (data
may be fetched from memory)
Store results if necessary
Repeat!

Слайд 9Registers
Temporary storage containers used inside the CPU
Extremely fast
Fixed size, usually multiples
of 8-bits
Also called a “word”
Example: 32-bit machines (4-byte words)
How large is a word in a 64-bit machine?

Слайд 10Cache
Slower than registers
Faster than RAM
Located in front of main RAM
Different levels
of cache
Level1 (L1) and Level2 (L2)
Size is usually around 1 MB
Level1 (L1) and Level2 (L2)
Size is usually around 1 MB
Слайд 16CD/DVDs
Lands and pits used to represent binary
Optical medium - lasers and
refraction used to read lands and pits
