Processor
Brains of the Computer
Most Important Element
CPU is housed in a single chip called
Microprocessor
What is an ALU?
Arithmetic Logic Unit
Performs Arithmetic and Logical Operations
What is a CU?
Control Unit
Extracts instructions from memory and decodes and executes them.
What is an Intel?
Uses more advanced architecture
What is an AMD?
Focuses more on including more cores, making budget friendly CPUs, allowing users to overclock heavily.

Are 486 processor sockets
Sockets 1, 2, 3, 6
Are pentium and pentium pro processor sockets
Sockets 4,5,7,8
is AMD CPUs where the pins are on the CPU. It has larger pins and allows for higher voltages and stability
PGA (Pin Grid Array)
is Intel chips where the pins are in the motherboard socket. It has smaller pins thus allows for higher and faster current.
LGA (Land Grid Array)
The required amount to install a chip in a standard 169pin screw Socket 1 motherboard
100 lbs of insertion force
Is required for all the higher-density sockets. Are handle-actuated.
ZIF (Zero Insertion Force)
The original OverDrive socket,
now officially called Socket 1, is
a 169-pin PGA socket.
Socket 1 (Intel and AMD)
Don’t have any mechanical components like fans
Passive Heatsinks
Heatsinks with fans or other devices that use power
Active Heatsinks
is called Pentium
OverDrive, it is not a full-scale
(64-bit) Pentium.
Socket 2
