a period of time when something (as a machine or factory) is functioning and available for use
The period of time a computer has functioned since last requiring a reboot.
Origin: up (adjective, computing) + time
Uptime is a measure of the time a machine, typically a computer, has been working and available. Uptime is the opposite of downtime. It is often used as a measure of computer operating system reliability or stability, in that this time represents the time a computer can be left unattended without crashing, or needing to be rebooted for administrative or maintenance purposes. Conversely, long uptime may indicate negligence, because some critical updates can require reboots on some platforms.
The New Hacker's Dictionary
Technically, a machine's time since last reboot; jargonically, how long a hacker has gone without sleep. “What's your uptime?” “Oh, about 28 hours so far, but I think I can probably do another 12.” This is, of course, a reference to the uptime command and the pride with which most Unix types note how long their computers go without reboots. Uptime is a testament to the stability of the OS and the stamina of the hacker.
