| computer | an electronic device that can store, retrieve and process data |
| ENIAC | name of the first COMPUTEr |
| 1953 | first TRUE computer |
| electronic | having a source of energy, other than its own |
| device | a helpful machine that can make life easier |
| store | to save, hold, or keep |
| retrieve | go get and bring back |
| process | to work with |
| data | information |
| input device | a device that can put data into the computer so it can be used |
| examples of an input device | keyboard, mouse, scanner, camera |
| output device | a device that allows the computer to use and give back the data that has been put in |
| examples of an output device | monitor, printer, speakers |
| keyboard | an electronic input device containing an arranged set of keys by which documents can be created |
| Christopher Sholes | creator of the keyboard |
| 1873 | date the keyboard was created |
| typewriter | the machine for which the keyboard was created |
| the arrangement of the keys on the keyboard | from most commonly used keys to least commonly used keys |
| mouse | a pointing device that is usually attached to a computer by a cable |
| 1984 | date of the first successfully used mouse |
| the only "extra" keys on the original keyboard | Space Bar, Shift |
| processor | the "brains" and operating system of the computer |
| CPU stands for... | Central Processing Unit |
| What did integrated circuits make possible? | processor, or CPU |
| synonym for processor | CPU |
| integrated circuit | a complex set of connections and instructions electronically etched or imprinted on a "chip" |
| chip | a metal plate or card with electronically etched data |
| program | a block of instructions loaded into the processor that will tell the computer what to do and how to do it |
| 1962 | the year integrated circuits were created |
| word processor | a computer program where documents can be created and edited |
| advantage of a word processor over a typewriter | you can edit and make changes to your work without beginning again |
| document | a written paper |
| binary code | the language used by the computer |
| zero and one | the only numbers read by a computer |
| character | a letter, number or symbol typed from a keyboard |
| byte | a unit of storage containing one "keyed" character |
| 1 character | equal to 1 byte |
| bit | the smallest unit of data used by the computer |
| 1979 | the year the word processing program was created |
| 1 byte | equal to 8 bits |
| 1946 | date of the first "computer" |
| function of a computer | store, retrieve, and process data |
| compute or calculate | the only thing ENIAC could do |
| synonym for integrated circuit | "chip" |
| synonym for "byte" | character |
| how a keyboard puts data in | by typing |
| how a mouse puts data in | point and click |
| how a scanner puts data in | make a copy |
| how a camera puts data in | take a picture |
| how a monitor gives data back | shows our work in words and pictures |
| how a printer gives data back | makes a hard copy |
| how speakers give data back | with sound |
| difference between scanner and printer | scanner is input device; printer is output device |
| What made the processor possible? | integrated circuits |
| 95 | number of characters on a keyboard |
| difference in a card and a chip | card is blank; chip has data |
| Where does the processor find the instructions to run a program? | on an integrated circuit |
| similarities of a scanner and printer | they are both devices that make copies |
