## What is a nanosecond used for?

A nanosecond (ns or nsec) is one billionth (10-9) of a second and is a common measurement of read or write access time to random access memory (RAM).

## What is a nanosecond example?

Abbreviated as ns or nsec, a nanosecond is a unit of time representing . 000000001 (10-9) or 1 billionth of a second. Computer memory speed is often represented in nanoseconds, for example, 60ns, 40ns, and 10ns are all different speeds of time it takes for the computer to access the memory.

How far does light travel in nanoseconds?

Light travels about 300,000 kilometers (or 186,000 miles) in one second. That means it goes about 30 centimeters — about one foot — in one nanosecond.

### What is faster than a nanosecond?

A picosecond, femtosecond, attosecond, zeptosecond and yoctosecond are all smaller than a nanosecond, each smaller than the next by a thousandths of a second.

### Is a nanosecond faster than the speed of light?

The speed of light is, stated in various units, 1 foot per nanosecond or 186 miles per millisecond or 300,000 kilometers per second. This is technically the speed in a vacuum (e.g. in space). Light travels a bit more slowly through media such as glass or water, but that’s not relevant for this discussion.

What is smaller than a nanosecond?

Picosecond is one trillionth of a second. Nanosecond is one billionth of a second. Microsecond is one millionth of a second. Millisecond is one thousandth of a second.

#### What comes after nano second?

Less than one second

Multiple of a second Unit Symbol
10−12 picosecond ps
10−9 nanosecond ns
10−6 microsecond µs
10−3 millisecond ms

#### Is there anything smaller than nano?

Anyway, smaller than nano? Of course… here’s the full list of prefixes that define the thousandths and millionths and billionths of nano… pico (million-millionth), femto (million-billionth), atto (billion-billionth), zepto (billion-trillionth), yocto (trillion-trillionth).

What can travel faster than light?

Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s. This speed limit makes it unlikely that humans will ever be able to send spacecraft to explore beyond our local area of the Milky Way.

## Is light faster than nanosecond?

What is smaller than nanoseconds?

### What is the opposite of nano?

The prefix nano is typically used to mean either: – one-billionth of a given unit, e.g., one nanosecond. – Very small, tiny, or minute….What is the opposite of nano?

massive big
prodigious tremendous
vast mighty
ponderous stately
walloping humongous

### What is a nanosecond (ns)?

What is a Nanosecond? Abbreviated as ns or nsec, a nanosecond is a unit of time representing .000000001 (10 -9) or 1 billionth of a second. Computer memory speed is often represented in nanoseconds, for example, 60ns, 40ns, and 10ns are all different speeds of time it takes for the computer to access the memory.

#### What is the difference between nanoseconds and milliseconds?

In computers, the speed of reading and writing to random access memory (RAM) is measured in nanoseconds. By comparison, the speed of reading or writing to a hard drive or a CD-ROM player, or for information to travel over the Internet, is measured in milliseconds (thousandths of a second), which are a million times longer than nanoseconds.

#### What does nano-mean in measurement terms?

In measurement terms such as nanosecond, nanogram, and nanometer, nano- means “billionth;” in other kinds of words, its meaning isn’t quite so precise. In computers, the speed of reading and writing to random access memory (RAM) is measured in nanoseconds. By comparison, the speed of reading or writing to a hard drive…
