OSI Model

time certification that can help you to get a job in the exciting IT (Internet Technology) field.  One of the first areas of study is the seven layer OSI Model.  The better you understand the OSI Model the better you will understand computer networking.  I would strongly suggest that you get very familiar with this model, the associated protocols, functions, equipment, and PDU’s at each layer.

PDUs (protocol data units)

PDUs are data packets associated with each level of the OSI Model.  Layer 1 the Physical layer the PDU is called a Bit.  Layer 2 the Data Link layer the PDU is called a Frame.  Layer 3 the Network layer the PDU is called a Packet.  Layer 4 the transport layer the PDU is called a Segment.  Above layer 4 the PDU is called Data.

The study of  Computer Network Training and Computer Repair Training can lead to some very rewarding careers.  But remember the OSI Model is the key to understanding how networks function.

The Computer Repair Training website has some additional information you might find helpful.
