Rock's Law
,Give this one a try later!
The cost of capital equipment to build semiconductors will double every
four years.
Asynchronous Circuit
Give this one a try later!
Circuits that becomes active the moment any input value changes.
Hollerith Card

Focuses on standards for telephony and other data communication
systems.
Combinational Logic
,Give this one a try later!
Used to build circuits that contain basic Boolean operators, inputs, and
outputs.
• The outputs are directly dependent on the values of the inputs.
ASCII
Give this one a try later!
Encodes characters (like "I" and "S") into decimal numbers that can then be
encoded into binary or hexadecimal. • ASCII representation of characters
require 8 bits.
Memory-Address Register
Give this one a try later!
Register that holds the memory address of the data being referenced.
Interrupt Vector Table
Give this one a try later!
A list of addresses of routines that can be executed through interrupts.
, Babbage Analytical Engine (1833)
Give this one a try later!
• The first machine we could reasonably call a computer. • Used Jaquard's
concept of punched cards to store programs.
Synchronous Circuit
Give this one a try later!
Use clocks to order events.
• Clock - A circuit that emits a series of pulses with a precise pulse width
and a precise interval between consecutive pulses. •
Clock Cycle Time - The interval between consecutive pulses. Measured in
Megahertz (MHz) or GigaHertz (GHz).
