A bit on the operation of cellular network security and firewalls.

Studying on the processes needed to secure connections using cryptography and IP datagrams.

On network security methods and systems, and how they can be used to protect the data. Examples given like RSA Algorithms.

A bit on the difference in protocol stacks for Wireless Networks compared with wired networks.

Analyzing the IEEE 802.11 protocol and dealing with Wireless Networks. Mainly the method required to connect to a network and avoid collisions on the link level.

CDMA Protocol for wireless networks and starting with the 802.11 protocol.

On how Virtual Local Area Networks (VLANs) work and how data centers operate. Didn't spend as much time here since its beyond my interest.
Also read about how a simple web page request is made by integrating all the available protocols into a single one.
I wish there was more code and network assignments and tutorials. So far it has been quite theoretical.

On the collision detection protocols to ensure link-layer networks can transmit without clogging the transmission lines. Starting a review on the Ethernet protocol, its strengths and operational methods.

Link Layer protocols to transfer datagrams and how they can be used when multiple node devices exist, thus requiring broadcast and handling turns.

The Network Layer Protocol seen from the Connection Level and how application based routing is better and faster to update than circuit based routing.
