Network Fundamentals Flashcards
(22 cards)
What is a client?
Device that users use to access the network (workstation, laptop, tablet)
What is a Server?
Provide resources to the network (mail server, file server)
What is a Hub?
Older technology, connecting devices but not commonly used due to limitations
What is a Switch?
Smarter hub that ensures security and efficient bandwidth utilization
Enables wireless devices to connect to a wired network using radio frequency waves
Wireless Access Point
Connect different networks, make intelligent forwarding decisions based on IP address
Router
Security barrier between internal network and the internet, monitors and controls traffic
Firewall
Distributes Network/application traffic across servers
Load Balancers
Act as intermediaries between user devices and the internet, enhancing security and privacy
Proxy Server
Detect Unauthorized access or anomalies
Intrusion Detection Systems (IDS)
Detect and take action to prevent intrusions
Intrusion Prevention Systems (IPS)
Manage flow control in software-defined networking (SDN)
Controllers
Dedicated file storage systems providing data access to authorized clients
Network-attached Storage (NAS) devices
High-speed network for consolidated block-level data storage
Storage Area Network (SAN)
Physical material used for data transmission
Media (cables)
Connects networks over large areas
Wide Area Network (WAN) Links
Utilizes a dedicated server for centralized access to files, scanners, printers, and resources
Client/Server model
Client/Server Model benefits
Centralized Administration/Easier Management/Better Scalability
Client/Server Model downsides
Higher Cost/requires dedicated hardware and specialized skillsets
Direct Sharing of resources among peers, difficult administration and backup due to dispersed files on different machines
Peer-to-peer model
Peer-to-Peer model Benefits
low cost/no specialized infrastructure or hardware
Peer-to-Peer model downsides
decentralized management/poor scalability for large networks
