Study Notes
Module Objectives
- The module explains the impact of modern network technologies on daily life and includes various topics like network components, types of networks, security, and professional opportunities.
Networks Affect Our Lives
- Communication is vital, and modern networks enhance connectivity beyond traditional means.
- Networks enable the creation of global communities, emphasizing a world without borders.
Network Components
- Hosts, or end devices, are computers on a network.
- Servers provide various services, including email, web, and file hosting.
Common Types of Networks
- Local Area Network (LAN): Covers small geographical areas, high-speed, managed by a single entity.
- Wide Area Network (WAN): Spans large geographical areas, connects multiple LANs, typically managed by service providers.
- The internet is a global interconnection of LANs and WANs, maintained by organizations like IETF and ICANN.
- Intranet: A private network within an organization for internal use.
- Extranet: Provides secure access to external individuals from other organizations.
Internet Connections
- Internet architecture connects diverse networks increasing access and service variety.
Reliable Network
- Network Architecture: Involves technologies supporting data movement across networks.
- Characteristics of reliable networks: Fault tolerance, scalability, quality of service (QoS), and security are essential to meet user expectations.
Fault Tolerance
- Fault-tolerant networks limit failure impacts by creating multiple pathways for data.
- Packet switching technology allows data to be broken into packets taking different routes, enhancing reliability.
Scalability
- A scalable network can adapt to growth quickly without degrading service quality, achieved through adherence to standards and protocols.
Quality of Service (QoS)
- QoS ensures reliable delivery of data, especially for voice and video transmission, managing bandwidth efficiently.
Network Security
- Integral to all network sizes, encompassing measures to protect data and maintain service quality.
- Security involves a mix of protocols, technologies, and tools to mitigate threats from internal and external sources.
Security Threats
- External Threats: Include viruses, spyware, identity theft, and denial of service attacks.
- Internal Threats: Stemming from lost devices, employee misuse, or malicious intent.
Security Solutions
- Effective security employs multiple layers, including antivirus software and firewalls for small networks.
- Larger networks require specialized solutions like dedicated firewalls, access control lists (ACLs), and intrusion prevention systems (IPS).
The IT Professional
- Cisco Certified Network Associate (CCNA) certification verifies knowledge of fundamental technologies and skills in emerging areas like security and automation.
- New DevNet certifications are available to recognize skills in software development relevant to networking roles.
