Study Notes
Computer Networking Concepts
-
Primary purpose of computer networking: To enable computers to share resources (email, files, media etc), and enable web browsing.
-
Network category for single building: Local Area Network (LAN).
-
Network spanning multiple cities: Metropolitan Area Network (MAN).
-
Data center network role: Linking multiple servers and data to be accessible to users in remote locations.
-
Transport Layer role (OSI Model): Ensures error-free end-to-end data delivery.
-
OSI layer for data translation: Presentation Layer.
-
Data Link Layer function: Manages error recovery, flow control, and data sequencing. It also defines electrical and mechanical connections.
-
Wireless vs. Wired Networks: Wireless networks provide mobility but can be slower and have potential security issues.
-
Hub function in wired networks: Broadcasts data to all connected devices.
-
Device responsible for monitoring network traffic and security: Firewall.
-
Star Topology description: All devices are connected to a central hub or switch.
-
Mesh Topology failure: The network can still operate via alternate paths.
-
Wired vs. Wireless Networks Advantage: Faster data transfer speeds and less susceptible to interference with wired networks.
-
Token Ring topology disadvantage: If an error corrupts the token, communication can stop.
-
Router Function: Forwarding data between networks, connecting wireless devices to wired networks, and assigning IP addresses.
-
Wi-Fi Modem components: Combines the functionality of a modem and a router.
-
OSI layer responsible for routing (packet creation): Network Layer.
-
Point-to-Point Topology: Two devices are directly connected.
-
Wired network device (not a router or switch): LAN Ethernet Cable.
-
Bus Topology Data Sharing: All devices share the communication medium, potentially leading to data collisions.
-
Importance of internet privacy: Protecting personal data from identity theft and malicious activity.
-
VPN function: Encrypts incoming and outgoing internet traffic.
-
Social Media Privacy Practices: Setting social media accounts to private, limiting personal information shared.
-
Multi-factor Authentication (MFA) function: Adds an extra verification step to log in to an account.
-
Wi-Fi Protected Access 3 (WPA3) Feature: Encrypts past sessions even if the server's private key is compromised.
-
Intrusion Detection System (IDS) function: Monitors and analyzes network traffic for malicious activity.
-
Consequence of network failure: Revenue loss.
-
Network Downtime Prevention: Regular monitoring of cables and devices, maintaining cables, and performing routine checks.
-
Network failure consequences for business: Possible legal repercussions from non-delivery of work and a damaged reputation.
-
Firewall function: Monitors and filters incoming and outgoing network traffic, protecting against unauthorized access.
-
Best practice to avoid phishing attacks: Double-checking the URL of suspicious links before clicking.
