Study Notes
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
Network Trends
- 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
