The organizational structure described here, which is known as vertical organizational structure, is also commonly identified as tall organizations.
They usually have hierarchical structures, with the CEO being at the very top of the layer. Tall organization have multiple levels, compared to its counterpart, the flat organization or horizontal, which would only have one level.
The <DEL> or <Delete> key makes the first character AFTER the cursor
disappear, and everything after it then moves back one space to close up
the hole.
Example:
If I have this in my document ... Most trees are green.
And my cursor is after the 'a', like this: Most trees a|re green.
Now, if I hit the <delete> key, it deletes the
'r' after the cursor, and the hole closes up,
and the cursor stays where it is: Most trees a|e green.
Not a real memory but it points to physical memory.
