What are the two definitions of computers

An electronic device that stores and processes data in binary form according to instructions given to it in a variable program

An electronic device that accepts input, processes that input, and creates an output (desirable or undesirable)

Why were computers created

• eliminate human error

• make tasks easier to accomplish

• easier ways to communicate

• allow for greater development/design

What was the first computer

The Abacus

What are the different types of modern computing

• personal computers

• desktop computers

• laptop computers

• netbooks

• personal Digital Assistant

• Work stations

• servers

• mainframe

• super computer

• wearable computers

• data centers

• cloud computing

what are personal computers

general purpose and designed to be used by a single end-user

what are desktop computers

computer that fits on or under a desk which uses input and output devices for interaction. ex: mouses, monitor, keyboard

what are laptop computers

aka notebook, a portable computer close to the power and efficiency of a desktop.

what is a personal digital assistant

computer that fits in the palm of your hand to collective information like contacts, appointments, files, and programs

Work stations

an individual computer/group of computers which is used by a single user to preform work. (maybe in a cubicle idk)

what are servers

computing device that accepts and responds to requests made over a network

what is a mainframe

A large central computer with more memory, storage space, and processing power than a standard computer (a big iron computer)

what is a super computer

a computer or a collection of computers that act as one to process large amounts of data. Used for complex jobs like nuclear research or forecasting weather patterns

what are wearable computers

electronic devices worn on the human body. ex: smart watches

What are data centers or DC

facility used to store computers, servers, routers, switches, and other networking equipment in one place

what is cloud computing

describes services provided over a network by a collection of remote servers. Offers massive, distributed storage and processing power accessible by any internet-connected

What is the information Processing Cycle

it is input to processing to output & storage is optional/in-between

What is input

data or set of instructions entered into a computer

what is processing

when a computer receives an input understands it, and does what the instructions say

what is storage

keeping data/information for a short time or longer period

What is output

a computer gives you the result of the data processed or result of the instructions

Who was Ada Loveplace

The first programmer who wrote the first algorithm for Babbage’s analytical engine

Who was Charles Babbage

Founding Father of the computer who designed the first mechanical computer, the Analytical Engine

Who was Conrad Zuse

Built the first electromechanical programmable computer
