Telecommunications is the electrical transmission
of data between systems, whether it is analog, digital, or wireless
communication. The data can be converted (digital to analog), compressed,
encrypted, and multiplexed many times taking on different forms such a
datagram(UDP is one style), packet (IP), cell (ATM), and so on. When it all
works together the result is awesome.
As data travels around a network (telecomm or
otherwise) it must adhere to a set of rules to be transferred correctly and
semi-efficiently.
The most common and largest set of rules is known
as the Internet. The Internet is based upon the TCP/IP protocol, which adheres
to the world standard ISO layer model.
This domain includes:
- Network architecture and design
- Communication channels
- Network components
- Network attacks
DMZ
False Positive
Symmetric and Asymmetric Encryption
Subnetting
