What is a bridge in computer networking?
A bridge is a computer networking device that builds the connection with other bridge networks which use the same protocol. It works at the Data Link layer of the OSI Model and connects the different networks together and develops communication between them.
A bridge is a device that amplifies signals to extend the range of a network.
A bridge is a device that stores and forwards emails between servers.
A bridge is a computer networking device that encrypts data for secure transmission over the internet.
At which layer of the OSI Model does a bridge operate?
Data Link layer
Network layer
Transport layer
Application layer
A bridge connects two local-area networks (LANs) or two segments of the same LAN that use the same protocol.
True
False
Which device is responsible for connecting Hub 1 and Hub 2?
Bridge
Router
Switch
Repeater
How does a bridge forward data between network segments?
A bridge forwards data after inspecting the MAC address of the devices connected to every segment and forwards the data if the destination address resides on another interface.
A bridge forwards data by broadcasting all incoming packets to every segment regardless of the destination address.
A bridge forwards data only to devices with IP addresses matching its own segment.
A bridge forwards data by converting all packets to broadcast messages before sending them to all segments.
What is the main advantage of learning bridges over traditional bridges?
Learning bridges build a list of the MAC addresses on the interface by observing the traffic on the network, which is a leap in the development of manually recording MAC addresses.
Learning bridges require manual configuration of MAC addresses for each interface.
Learning bridges only work with wireless networks.
Learning bridges increase network congestion by broadcasting all packets.
Ethernet switches are gaining trend compared to bridges due to their ability to provide logical divisions and segments in the network.
