1 Network Fundamentals Flashcards
Encompass a diverse range of connections extending to both wireless networks and wired networks
Networks
Compare and contrast networking appliances, applications, and functions
Objective 1.2 - Domain 2 - Network Implementation - Network Fundamentals
Compare and contrast network topologies, architectures, and types
Objective 1.6 - Domain 2 - Network Implementation - Network Fundamentals
Given a scenario, select and configure wireless devices and technologies
Objective 2.3 - Domain 2 - Network Implementation - Network Fundamentals
Devices that users access the network with
Clients - Network Component
Provide resources to the network
Servers - Network Component
Older network devices that connect other devices like clients and services over a local area network;
They have limitations such as increased network errors due to their broadcasting nature
Hubs - Network Component
βSmarter hubsβ that provide more security and more efficient bandwidth utilization
Hubs were first developed, but over time they evolved into bridges, and then into what we use today which is __
Switches - Network Component
Allow wireless devices to connect to a wired network
Wireless Access Points (WAPs/APs) - Network Component
Used to connect different networks together
They now predominantly rely on the internet protocol to route the traffic across the network
Routers - Network Component
Security barriers between internal networks and the external world (usually the internet)
Firewalls - Network Component
Devices or software that distribute network or application traffic across multiple servers ;
They prevent any one server from becoming a bottleneck, improving overall network performance
Load Balancers - Network Component
Acts as an intermediary between a userβs device and the internet
Functions to web filtering, shared network connections, data caching to improve overall performance, and enhance security and privacy
Proxy - Network Component
Detective unauthorized access or anomalies and alert administrators
Intrusion Detection Systems (IDS) - Network Component
Not only detect threats, but also take action to prevent intrusion
Intrusion Prevention Systems (IPS) - Network Component
In Software-Defined Networking (SDN) context, these are central units used to manage flow control to networking devices
Controllers - Network Component
Dedicated file storage system that provides data access to a heterogenous group of clients
Network-attached Storage (NAS) Devices - Network Component
High-speed network that provides access to consolidated block-level data storage
Storage Area Networks (SANs) - Network Component
In network, it refers to the physical materials used to transmit data
Media - Network Component
Used to connect networks over large geographical areas
Wide Area Network (WAN) Links - Network Component
Utilizes a dedicated server to provide access to network resources (files, scanners, printers, etc.)
Administration and backup are easier
Pros
- Centralized administration
- Easier management
- Better scalability
Drawbacks
- Costs more
- Requires dedicated OS
- Requires specialized skillset
Client / Server Model - Network Resources
Peers or other machines (e.g., laptops, desktops) can share resources together directly
Pros
- Lower cost
- No specialized OS
- No dedicated resources
Drawbacks
- Decentralized management
- Inefficient for large networks
- Poor scalability
Peer-to-Peer Model - Network Resources
