What are the different methods used by switches to handle frames, and how do they impact network efficiency and error checking?
Switches are essential devices in computer networking that operate at the data link layer (Layer 2) of the OSI model. They are responsible for forwarding data frames within a local area network (LAN) based on the Media Access Control (MAC) addresses. Switches use various methods to handle frames efficiently, impacting network performance and error checking

Describe the role of bridges in network segmentation and how they enhance network performance compared to hubs.
Bridges play a crucial role in network segmentation by dividing a single network into smaller segments, known as collision domains. This division helps in reducing network congestion, improving security, and enhancing overall network performance. Bridges operate at the data link layer of the OSI model and make forwarding decisions based on MAC addresses. They function
Explain the significance of MAC addresses in Ethernet frames and how they contribute to network uniqueness and efficiency.
MAC addresses play a pivotal role in Ethernet frames within computer networking, specifically in the context of switching. These addresses are essential for ensuring network uniqueness and efficiency by facilitating the proper delivery of data packets to their intended destinations. Understanding the significance of MAC addresses in Ethernet frames requires delving into how switching works

How do hubs differ from switches in terms of network functionality and data processing capabilities?
Hubs and switches are both networking devices used to connect multiple devices in a Local Area Network (LAN). However, they differ significantly in terms of network functionality and data processing capabilities. Hubs operate at the physical layer (Layer 1) of the OSI model. They are essentially multi-port repeaters, which means they broadcast data packets to
Are switches and hubs the same devices?
Switches and hubs are not the same devices in the field of computer networking. While both switches and hubs are used to connect devices within a network, they differ in functionality and the way they handle network traffic. Understanding the differences between switches and hubs is crucial in the field of cybersecurity as it can
