Editor's Summary: Telecommunications and networking use various mechanisms, devices, software and protocols that are interrelated and integrated. Networking is one of the more complex topics in the computer field, mainly because so many components are involved. A network administrator or engineer must know how to configure networking software, protocols and services, and devices; deal with interoperability issues; install, configure and interface with telecommunication software and devices; and troubleshoot effectively. A security professional must understand these issues and the vulnerabilities that can arise within the network.
The following are a few of the topics that are covered in this domain:
- Protocol stack models: OSI, TCP/IP stack models, their abstraction layers, associated protocols and their relationship to each other
- Core technologies: Network topologies, LAN, MAN and WAN, cabling and data transmission types, network and telecommunications devices and services, and Web-based intranet and extranet Web technologies
- Network components and services: Network devices and services, telecommunications, devices and resource management
- Extension technologies: Remote access methods and technologies, and wireless technologies
