Study Notes
Networking Fundamentals
- Definition: Networking is the practice of connecting computers and devices to share resources and information.
-
Types of Networks:
- LAN (Local Area Network): Covers a small geographic area, like a home or office.
- WAN (Wide Area Network): Covers larger geographic areas, connecting multiple LANs.
- MAN (Metropolitan Area Network): Spans a city or a large campus.
-
Key Protocols:
- TCP/IP: Foundation of internet communication; includes protocols like HTTP, FTP, and SMTP.
- OSI Model: Seven layers that define how data is transmitted over a network (Physical, Data Link, Network, Transport, Session, Presentation, Application).
-
Network Devices:
- Routers: Forward data packets between networks.
- Switches: Connect devices within a LAN and manage data traffic.
- Access Points: Allow wireless devices to connect to a wired network.
CISCO Certification Tracks
- CCNA (Cisco Certified Network Associate): Entry-level certification focusing on networking fundamentals and IP connectivity.
- CCNP (Cisco Certified Network Professional): Intermediate certification for advanced networking skills and deeper knowledge in areas like routing, switching, and troubleshooting.
- CCIE (Cisco Certified Internetwork Expert): Expert-level certification requiring substantial networking experience, focusing on design, implementation, and troubleshooting complex network infrastructures.
- Specializations: Additional certifications in areas like Security, Collaboration, Data Center, and Service Provider.
CISCO Collaboration Tools
- Webex: Cloud-based video conferencing and online meeting platform.
- Cisco Unified Communications: Integrates voice, video, messaging, and presence into one platform.
- Cisco Jabber: Provides instant messaging, voice, video, and conferencing capabilities.
- Cisco TelePresence: High-definition video conferencing system for immersive meetings.
CISCO Routers And Switches
-
Routers:
- Connect multiple networks and manage traffic between them.
- Examples include Cisco ISR (Integrated Services Router) and ASR (Aggregation Services Router).
-
Switches:
- Operate at Layer 2 (Data Link) and Layer 3 (Network) of the OSI model.
- Types include:
- Managed Switches: Allow for control over the network and monitoring.
- Unmanaged Switches: Simple plug-and-play devices with no configuration options.
-
Key Features:
- VLAN (Virtual Local Area Network) support for network segmentation.
- QoS (Quality of Service) for prioritizing network traffic.
CISCO Security Solutions
- Firewalls: Protect networks from unauthorized access; examples include Cisco ASA (Adaptive Security Appliance).
- Intrusion Prevention Systems (IPS): Monitor network traffic for suspicious activity and block potential threats.
- VPN (Virtual Private Network): Secure remote access solutions using technologies like SSL and IPsec.
- Identity Services Engine (ISE): Provides identity and access control for network devices, enforcing security policies.
- End-Point Security: Protects devices connected to the network from vulnerabilities and malware.
Networking Fundamentals
- Networking connects computers and devices for resource and information sharing.
- LAN (Local Area Network): Serves a small area like homes or offices.
- WAN (Wide Area Network): Covers broad regions, linking multiple LANs.
- MAN (Metropolitan Area Network): Encompasses cities or large campuses.
- TCP/IP: Core framework for internet communication, including protocols such as HTTP, FTP, and SMTP.
- OSI Model: Comprised of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application, outlining data transmission processes.
-
Network Devices:
- Routers: Direct data packets among various networks.
- Switches: Facilitate connections within a LAN and regulate data flow.
- Access Points: Enable wireless devices to join wired networks.
CISCO Certification Tracks
