Networking Pathway Lesson 1

Networking Overview

• Classification of hackers:
  • Black Hat - malicious hackers
  • Gray Hat - hackers who may violate ethical standards
  • White Hat - ethical hackers who assist in security

Networking Pathway

• Information Technology (IT):

  • Involves computers, software, networks, and technologies for data management.
  • Encompasses various practices for effective data processing.

• Roles in Networking:

  • Network Architect - Designs network structures.
  • Network Engineer - Implements and manages networks.
  • Cloud Engineer - Oversees cloud computing services.
  • Database Administrator - Manages databases and ensures data integrity.
  • Security Specialist - Focuses on network security and risk management.
  • Telecommunication Specialist - Handles communication systems and technologies.

Network Administration

• Branch of engineering focused on managing human-computer systems.
• Responsibilities of a Network Administrator include:
  • Designing the network infrastructure.
  • Setting up the network for operation.
  • Maintaining network functionality.
  • Expanding network capabilities as needed.

Designing the Network

• Key considerations in network design:
  • Budget - Financial resources available for network setup.
  • Type of Traffic:
    • Data (uses TCP/IP)
    • Voice (uses UDP) - streamlined telecommunication.
    • Video (uses UDP) - real-time streaming with no playback options.
  • Number of Users - Anticipated user base influences design.
  • Compatibility - Ensuring devices and software work seamlessly together.

Protocols

• TCP/IP - Transmission Control Protocol/Internet Protocol, foundational for internet communications.
• UDP - User Datagram Protocol, for applications needing faster transmission.

Career Path in Networking

• Certifications related to Networking:
  • CCST - Cisco Certified Support Technology.
  • CCNA - Cisco Certified Network Associate.
  • CCNP & CCIE - Cisco Certified Network Professional/Expert.
  • Specializations in Cybersecurity and RHCE (Red Hat Certified Engineer).

Network Administration Goals

• Ensure infrastructure and systems are operating at 100% efficiency.

Types of Errors in Network Administration

• Hardware Failure - Issues with physical components.
• Application Errors - Problems arising from software functions.
• Data Corruption - Loss or alteration of data integrity.
• Power Outage - Loss of electricity affecting systems.
• Security Concerns - Vulnerabilities that can be exploited.

Types of Administrators

• Database Administrator - Ensures data integrity and database system efficiency.
• Network Administrator - Maintains network infrastructure and troubleshoots issues.
• Security Administrator - Focuses on security measures and devices.
• Web Administrator - Manages web presences and associated security.
• Technical Support - Assists users with computer-related difficulties.

Network Management Functional Areas (FCAPS)

• Forum Management:

  • Problem identification and resolution process.
  • Steps: Discover, Isolate, and Fix/Replace issues.

• Configuration Management:

  • Involves configuring network devices and software to control data behavior.

• Accounting Management:

  • Tracks resources and user access within the network environment.
