safe and secure.

Behead me and I become

What am I?

I am an eight letter word and I am a computer terminology.
The second, third and fourth letters make an animal.
The fourth, fifth, sixth, seventh and eighth letters make a weapon.
The first, second, third and fourth letters can be taken as an outcome of any exam.
The fifth, sixth, seventh and eighth letter combine to form a high end typing software.

Can you tell who am I ?

What am I?

What is full of holes but still holds water?

What is in seasons, seconds, centuries and minutes but not in decades, years or days?

The first person saw the bridge step on it and crossed,
the second person saw the bridge did not step on it but crossed,
the third person did not see the bridge did not step on it but crossed.
Who are these people?

Two in a corner, one in a room, zero in a house, but one in a shelter. What am I?

Spelt forwards I’m what you do every day, spelled backwards I’m something you hate. What am I?
