Study Notes
Course Information
- Course title: INFO 1220 Network Fundamentals
- Course provider: Fanshawe College
Introduction to Networking
- Networking encompasses various communication methods
- Examples include word of mouth, cell phones, and computer networks
- Computer networks connect devices and transfer data, voice, and video through cables, fiber-optics, and radio waves
Computer Networks
- Systems include computers, print devices, network devices, and software
- Networks transmit data, voice, and video over different types of media (cables, fiber-optics, radio waves)
- A major advantage is the ability to share information across the network
Networks
- Networks support various activities, including learning, communication, work, and play
Networks of Many Sizes
- Vary from two computers to millions of devices
- Networks accommodate diverse needs in businesses and organizations, facilitating efficient communication and access to information
Client-Server
- Computers on a network can be classified as hosts
- Servers are hosts providing information to other hosts (clients)
Peer-to-Peer
- A network where computers can act as both clients and servers
Network Components
- Devices, media, and software are the physical elements of the network
- Hardware includes devices like laptops, PCs, switches, routers, and wireless access points
- Data flows through intermediate devices and arrives at end devices
Network Components (Devices)
- End Devices - Desktop computers, laptops, printers, IP phones, and wireless tablets
- Intermediary Devices - Routers, switches, multi-layer switches, and firewall appliances
Network Components
- Different types of media facilitate data transmission.
- Examples include metallic wires, glass/plastic fibers, and wireless transmission (electromagnetic waves)
Types of Networks
- Local Area Networks (LANs): Network infrastructure covering a small geographical area
- Wide Area Networks (WANs): Cover larger geographical areas, often using telecom service providers' infrastructure
- Other types include Metropolitan Area Networks (MANs), Wireless LANs (WLANs), and Storage Area Networks (SANs)
WANs
- LANs are interconnected using WAN services and technologies
- Includes satellite, leased lines, cellular, DSL and cable connections
Internet Access Technologies
- Various technologies provide access to the Internet
- Internet Service Providers, Broadband Cable, DSL, Wireless WANs, and Mobile services are some examples
Home/Small Office Internet Connections
- DSL, Cable, Cellular, Satellite, and Dial-up connections provide Internet access for homes and small offices
Internet Connections (Business)
- Dedicated leased lines, Metro Ethernet, DSL and satellite connections are used for business connections
New Trends
- Bring Your Own Device (BYOD)
- Online Collaboration
- Video Communications
- Cloud Computing
- Software-Defined Networking
- Internet of Things (IoT)
Bring Your Own Device
- The concept where users bring their own devices to access network resources
- This trend introduces new challenges to information security
Online Collaboration
- Communication tools for joint projects
- Enables students, employees, teachers, and customers to interact and work together
Video Communications
- A powerful tool used for both local and global communication.
Cloud Computing
- A trend changing the way people access and store data
- Personal files and backups are stored on servers over the internet
Software-Defined Networks(SDN)
- A network architecture that addresses scalable needs
- Decouples control plane (decision making) from the data plane (data forwarding)
Internet of Things (IoT)
- The continuous networking of existing physical devices (smart devices)
- Data exchange between these devices and the Internet occurs to make them efficient and accurate
Network Characteristics
- Fault tolerance
- Quality of Service
- Reliability
- Scalability
- Security
Fault Tolerance
- A network has multiple paths and mechanisms in place if a device or link fails
- Aims to reduce the impact of failures on users and operations
Scalability
- The capacity to grow and adapt to changing levels of network use
- Enables the incorporation of new or additional users, while preserving performance for existing users
Quality of Service (QoS)
- A mechanism that can establish and prioritize traffic
- Important for network applications and traffic prioritizing
Security
- An important aspect to protect resources and data from attacks
- Software and hardware protections exist alongside physical protection to prevent unauthorized access
Threats to Networks
- External threats - viruses, worms, trojan horses, spyware, adware, zero-day, hacker attacks, denial of service attacks, data interception, and identity theft
- Internal threats - lost, stolen devices, accidental misuse, malware-infected employees
Security Solutions
- Multiple layers to protect from threats
- Include antivirus, firewalls, access control lists, intrusion prevention systems, and virtual private networks
Network Equipment
- Network Interface Card (NIC)
- Switch
- Router
Network Layouts
- Topology diagram
LAN Physical Topologies
- Star
- Extended Star
- Bus
- Ring
WAN Physical Topologies
- Point-to-point
