the enterprise.

sometimes called the grapevine and might be observed
occurring in conversations, electronic mails, text messages
and phone calls between socializing employees.
6. BASED ON THE DIRECTION
(A) DOWNWARDS COMMUNICATION :
Communication between a superior and subordinate
is known as downward vertical communication.

which flows from a superior to a subordinate.

Upward communication means the flow of information
from the lower levels of the organization to the higher
levels of authority.

The transmission of information and understanding
between people on the same level of organization
hierarchy is called the horizontal communication.

neither in the same department nor on the same level
of organization hierarchy is called diagonal
communication.

COMMUNICATION : Communication does not
mean merely written or oral messages. It includes
everything that may be used to convey meanings
from one person to another, e.g., movement of lips
or the wink of an eye or the wave of hands may
convey more meaning than written or oral words.
