The phrase "keyed in" refers to entering information or data into a computer or other device by pressing keys. The spelling of the word 'keyed' is pronounced /ki:d/ [keed], with a long 'e' sound, followed by the 'd' sound. The 'ed' ending is pronounced as a separate syllable, not merged with the 'e' sound. The word 'keyed' is formed by adding '-ed' to the verb 'key', which means to operate a mechanical device by pressing keys, such as a typewriter or piano.
Keyed in refers to the act of inputting information, data, or commands into a computer system or device using a keyboard. It commonly involves manually typing or pressing keys on a keyboard to enter text, numbers, or symbols, providing instructions to the computer or executing specific functions.
The term "keyed in" originated from physical keyboards where each key is pressed to transmit a corresponding signal, translating the action into readable and interpretable information by the computer. It is an essential part of interacting with computers and various digital platforms, allowing users to communicate with the technology and provide necessary input.
Keyed in may also refer to the process of typing information accurately and precisely, ensuring that the intended data is correctly entered without errors. This can include typing in passwords, usernames, commands, text content, or any other input required for the function or operation of a computer program, application, or system.
The phrase "keyed in" can be used in various contexts, including computer programming, data entry, document creation, online communication, and any situation where manual typing is involved. It emphasizes the physical and intentional act of using a keyboard to transmit instructions or input to a computer system.
The phrase "keyed in" is derived from an older term, "keying", which was initially used in the field of telegraphy. In telegraphy, operators would transmit messages by pressing keys on a telegraph key, which would either open or close an electrical circuit, allowing the transmission of signals. The term "keying" referred to the action of pressing these keys.
Over time, the term "keyed in" expanded its meaning and became associated with the process of entering information or data using a keyboard, such as on a typewriter or computer. It signifies the action of inputting information by pressing keys on a keyboard, similar to how telegraph operators would "key in" their messages.
