What is the primary function of a router in a network?
Directs Traffic: Routes data between devices on different networks.
Assigns IP Addresses: Often uses DHCP to assign IP addresses to devices.
Manages Network Traffic: Determines the best path for data to travel.
Provides Security: Can include firewall features to protect the network.
Connects Networks: Links home or local networks to the internet.
How does a router differ from a switch in terms of its functionality?
Router
- Connects different networks.
- Routes data using IP addresses.
- Provides NAT and DHCP.
Switch
- Connects devices within the same network.
- Forwards data using MAC addresses.
- Operates at Layer 2.
What is NAT and how does it relate to routers?
NAT: Translates private IPs to a public IP.
Purpose: Allows multiple devices to share one public IP.
Router Role: Manages NAT for local network devices.
Benefits: Saves IPs, hides internal addresses, and adds security.
What is the difference between a managed and an unmanaged switch?
Managed Switch
- Configuration: Allows configuration and management (e.g., VLANs, QoS).
- Features: Offers advanced features (e.g., network monitoring, SNMP).
- Control: Provides greater control over network traffic and performance.
- Price: Generally more expensive.
Unmanaged Switch
- Configuration: Plug-and-play, no configuration needed.
- Features: Basic functionality, no advanced features.
- Control: Limited control over network traffic.
- Price: Generally less expensive.
Which type of switch allows for more granular control over network traffic: managed or unmanaged?
- Managed
What are VLANs and how are they used with managed switches?
VLANs (Virtual Local Area Networks):
- Definition: Segment a network into logical groups.
- Purpose: Improve efficiency, security, and management.
- Isolation: Different VLANs can’t communicate directly.
- Managed Switches: Tag frames with VLAN IDs.
- Configuration: Set up via switch settings.
- Benefits: Reduce traffic, enhance security, simplify management.
How does a switch learn the MAC addresses of devices on the network?
What type of switch would typically be used in a home / small office network?
- Unmanaged
What is the purpose of a wireless access point (WAP)?
How does an access point differ from a router?
What are some common features of modern wireless access points?
What is a patch panel used for in a network?
How does a patch panel simplify cable management?
What are the benefits of using a patch panel in a structured cabling system?
What is the primary purpose of a firewall in a network?
