Network Types
This type of network covers a small area, like a home or office.
What is a LAN (Local Area Network)?
This is the first layer of the OSI model, dealing with cables and radio waves.
What is the Physical Layer?
This device simply repeats bits to all ports and is considered a Layer 1 device.
What is a Hub?
This connector is commonly used for Ethernet cables and has 8 pins.
What is an RJ-45 connector?
This protocol is used for traditional web browsing and uses TCP port 80.
What is HTTP?
This network interconnects nearby buildings, often found on college campuses.
What is a CAN (Campus Area Network)?
Ethernet switches operate at this OSI layer and use MAC addresses.
What is the Data Link Layer?
This device learns MAC addresses and forwards frames intelligently.
What is a Switch?
This type of twisted pair cable has additional shielding to protect against EMI.
What is STP (Shielded Twisted Pair)?
This protocol secures web traffic and uses TCP port 443.
What is HTTPS?
This network spans a city and connects multiple offices.
What is a MAN (Metropolitan Area Network)?
Routers operate at this layer, using logical addressing like IP addresses.
What is the Network Layer?
This device connects different networks and forwards packets based on IP addresses.
What is a Router?
This fiber optic cable type supports longer distances and only one path for light.
What is Single-Mode Fiber?
This protocol can use either TCP or UDP port 53 to resolve domain names.
What is DNS?
This network connects devices over large geographical regions, even globally.
What is a WAN (Wide Area Network)?
TCP and UDP operate at this layer, handling reliable and unreliable connections.
What is the Transport Layer?
This device protects networks from outside threats by filtering traffic.
What is a Firewall?
This color code standard swaps the orange and green pairs in Ethernet cables.
What is T568A/B?
This protocol automatically assigns IP addresses and uses UDP port 67.
What is DHCP?
The connection between a gaming console and its wireless controller is an example of this network type.
What is a PAN (Personal Area Network)?
HTTP and DNS protocols operate at this OSI layer.
What is the Application Layer?
This device analyzes network traffic for known attack signatures and can block malicious packets before they reach the network.
What is an IPS (Intrusion Prevention System)?
This modular port allows switches to support different media types and speeds.
What is a Transceiver (e.g., SFP)?
This protocol synchronizes time across devices and uses UDP port 123.
What is NTP (Network Time Protocol)?
