Introduction to Networking

  • Introduction to networking is a module (CT043-3-1 & Version VE1)
  • Networking is important in modern life, like air, water, food, and shelter
  • Networking connects devices globally
  • Networks have no boundaries, connecting global communities and facilitating human interaction
  • Essential concepts include host/peer-to-peer, clients and servers, end devices/intermediary devices, and network media
  • Local Area Networks (LANs) and Wide Area Networks (WANs) connect to the internet
  • Key network trends include BYOD, online collaboration, video, and cloud computing
  • Network security needs to be addressed with security threats and solutions
  • The IT professional is essential in the understanding and maintenance of networking
  • Key terms that students should be able to use in exams include Host / Peer to Peer, Client and server, End Devices / Intermediary Devices, Network Media, Local Area Network / Wide Area Network, Fault Tolerant, Reliability, Scalability, Quality of Services, BYOD, Online Collaboration, Cloud Computing, Security Threats and Solutions.

Network Components

  • Every computer on a network is a host or end device
  • Servers provide information to end devices (email, web, file servers)
  • Clients send requests to servers for information
  • Examples of intermediary devices include switches, wireless access points, routers, and firewalls
  • Intermediary devices manage data flow, regenerate signals, maintain pathways, and notify devices of errors
  • Network media types include copper (electrical impulses), fiber-optic (light pulses), and wireless (electromagnetic waves)

Network Representations and Topologies

  • Network diagrams, called topology diagrams, use symbols to represent network devices
  • Key terms include network interface card (NIC), physical ports, and interfaces
  • Physical topology diagrams illustrate the physical location of devices and cable installation
  • Logical topology diagrams illustrate devices, ports, and addressing

Common Types of Networks

  • Network sizes vary greatly
  • Different sizes include small home networks, small office/home office (SOHO) networks, medium to large networks, and world-wide networks (like the internet)

LANs and WANs

  • LANs interconnect devices in a limited geographical area
  • LANs are administered by a single organization
  • WANs interconnects multiple LANs over very large areas
  • WANs are typically managed by multiple service providers

The Internet

  • The internet is a collection of interconnected LANs and WANs
  • LANs or WANs use various technologies to communicate

Intranets and Extranets

  • Intranets are private networks for internal members of an organization.
  • Extranets allow access to individuals outside an organization's network for specific reasons

Internet Connections

  • Many methods exist to connect to the internet
  • Popular options for home users include broadband cable, broadband DSL, wireless WANs, and mobile services
  • Organizations require faster connections for IP phones, video conferencing, and center storage
  • Businesses use business-class connections like business DSL, leased lines, and metro ethernet

Home and Small Office Internet Connections

  • Various options to connect to the internet including cable, DSL, cellular, satellite, and dial-up telephone

Business Internet Connections

  • Higher bandwidth and dedicated connections are often required for businesses
  • Managed services are also commonly used in business networking

The Converging Network

  • Networks have converged to use the same technologies for various types of communication
  • Data, voice, and video use the same network infrastructure
  • Same rules and standards apply for all data types

Reliable Networks

  • Four key characteristics for reliable networks: Fault Tolerance, Scalability, Quality of Service (QoS), and Security
  • Fault Tolerance is the ability of the network to continue operating even if some parts of the network have failed
  • Scalability is the ability of the network to handle a large amount of traffic and/or users with no impact to performance
  • QoS is the ability of a network to effectively prioritize communications to maintain quality and performance
  • Network security measures protect data and resources from unauthorized access

Network Security

  • External threats and internal threats to network security
  • Implementing security measures to address threats and vulnerabilities
  • Bring Your Own Device (BYOD), online collaboration, video communication, cloud computing
  • Powerline networking, wireless broadband, network security

The IT Professional

  • Cisco Certified Network Associate (CCNA) certification is important in demonstrating networking knowledge
  • Specialist certifications validate skills in networking and software development
  • Networking careers are offered through the Talent Bridge matching engine
