Whois & Analysis for vclock.com

An alarm clock or alarm is a clock that is designed to alert an individual or group of people at a specified time.

The primary function of these clocks is to awaken people from their night's sleep or short naps; they can sometimes be used for other reminders as well.

Most alarm clocks make sounds; some make light or vibration.

Some have sensors to identify when a person is in a light stage of sleep, in order to avoid waking someone who is deeply asleep, which causes tiredness, even if the person has had adequate sleep.

To turn off the sound or light, a button or handle on the clock is pressed; most clocks automatically turn off the alarm if left unattended long enough.

A classic analog alarm clock has an extra hand or inset dial that is used to show the time at which the alarm will ring.

Alarm clock functions are also used in mobile phones, watches, and computers.

Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, and into the future.

It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience.

Time is often referred to as a fourth dimension, along with three spatial dimensions.

The minute is a unit of time defined as equal to 60 seconds.

One hour contains 60 minutes.

Although not a unit in the International System of Units (SI), the minute is accepted for use in the SI.

The SI symbol for minutes is min (without a dot).

The prime symbol is also sometimes used informally to denote minutes.

In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid.

An hour (symbol: h; also abbreviated hr) is a unit of time historically reckoned as of a day and defined contemporarily as exactly 3,600 seconds (SI).

There are 60 minutes in an hour, and 24 hours in a day.
