Vacuum tube Vacuum tubes contain electrodes for controlling electron flow and were used in early computers as a switch or an amplifier.
Transistors The transistor ("transfer resistance") is made up of semi- conductors. It is a component used to control the amount of current or voltage used for amplification/modulation of an electronic signal. Punched cards Punch cards also known as Hollerith cards are paper cards containing several punched or perforated holes that were punched by hand or machine to represent data. Machine Language Machine language is a collection of binary digits or bits that the computer reads and interprets.
Assembly language An assembly language is a low-level programming language. Chapter Page Integrated Circuits The IC is a package containing many circuits, pathways, transistors, and other electronic components all working together to perform a particular function or a series of functions. Microcomputer Micro computer is used to describe a standard personal computer. High-level languages A high-level language is a computer programming language that isn't limited by the computer, designed for a specific job, and is easier to understand.
Natural Language Processing (NLP) Natural Language Processing is a method used in artificial intelligence to process and derive meaning from the human language. Robotics Robot is a term coined by Karel Capek in the to play RUR (Rossum's Universal Robots). It is used to describe a computerized machine designed to respond to input received manually or from its surroundings. Nanotechnology Nanotechnology is an engineering, science, and technology
