What I am
People call me an animal
Since I possess a tail
but it's in the opposite direction.
I can't travel beyond some point
Since I am bound by my tail.
Sometimes I don't have a tail
But still I can not travel that far.
Go to the right and the world is easy for you.
Go to the left and change your mode.
You touch me often, but I won't bite you.
So what am I?
A computer mouse
A mouse is an animal
The 'tail' comes out of the top, rather than the bottom
Some are wireless, so have no tail, but are still bound by the receiver's range
Going right takes you away from the keyboard, which is easy to do
I'm not sure about the left clue
You have your hand on it a lot without being bitten
Maybe you are
a keyboard
People call me an animal
that's the one I miss, maybe a reference to the keyboard cat?
Since I possess a tail
that's the wire
but it's in the opposite direction.
when I'm using it, the "tail" is indeed in opposite direction
I can't travel beyond some point
well, the wire must not be unplugged
Since I am bound by my tail.
bound with the computer
Sometimes I don't have a tail
wireless ones, maybe?
But still I can not travel that far.
Wireless, if I go too far, I might lose the signal
Go to the right and world is easy for you.
numpad in on the right, and make life easier, compared to using the other numbers
Go to the left and change your mode.
capslock is on the left, and often used to convey anger, on forums
You touch me often, but I won't bite you.
yes, I touch it very often (I wouldn't be able to answer, if not) .. and never been bitten
The correct answer has been posted, but this was my initial guess.
I think you are:
A ring buffer or FIFO (first-in, first-out) queue
People call me an animal
Since I possess a tail
but its in opposite direction.
Not sure about the animal part. The tail can end up in front of the head once the head wraps around after having reached the end of the buffer.
I cant travel beyond some point
Since i am bound by my tail.
A ring buffer is considered full when head = tail-1 (mod N). At this point, the head can no longer advance and so you can no longer push data to the ring buffer.
Sometimes I don't have a tail
But still I can not travel that far.
The tail points to stale data once it has caught up to the head, i.e. head = tail. Even starting with no tail, the head can only advance by N, where N is the (finite) size of the ring buffer.
Go to right and world is easy for you.
Go to left and change your mode.
A ring buffer always travels to the right, towards increasing memory, until wrap-around occurs after a total of N steps.
You touch me often, but I won't bite you.
A ring buffer can be used many times per second, allowing information to transfer at rates of 100s of MB per second.
