All devices share bandwidth.This is followed by an introduction to the OSI model - a 7-layer model that helps application developers design applications that run on any type of system or network. Each layer has its own specific job and responsibilities in order to ensure reliable and efficient communication. This chapter goes into the details of each layer and describes how Cisco views the definition of the OSI model.In addition, each layer of the OSI model defines a different type of device, and this chapter describes the various devices that work at each layer.Keep in mind that a hub is a physical layer device that forwards digital signals to all network segments except the receiving port. Switches use hardware addresses to separate networks and can separate conflicting domains. A router will separate broadcast domains (and conflict domains) and use logical addresses to send packets across the interconnected network.2.5 Exam PointsIdentify the possible causes of LAN traffic congestion. Placing too many hosts in a broadcast domain, broadcast storms, multicast transmissions, and low bandwidth are all possible causes of LAN traffic congestion.Point out the difference between /' in knowfull port wide choice city. Forest cable is an Ethernet term describing a situation where these network devices are located in the same network segment, and when one device sends a packet, it forces all other devices to listen for network idle state. In a plant otter, all devices receive all broadcasts in this segment.Distinguish between a MAC address and an IP address to describe how and when the two addresses are used in the network. A MAC address is a string of hexadecimal values that identifies the physical connection of a host. MAC addresses work at layer 2 of the 0SI model. IP addresses, which can be expressed as binary or decimal, are logical identifiers and work at layer 3 of the 0SI model. Hosts on the same physical segment identify each other by their MAC addresses, and when hosts are on different LAN segments or subnets, they use IP addresses to identify each other. Even if these hosts are located on different subnets, when the packets are routed to the destination network, the destination IP address is converted to a MAC address.Understand the differences between hubs, bridges, switches, and routers. A hub creates a conflict domain and a broadcast domain. A bridge separates the conflict domain, but creates a large broadcast domain. They all use physical addresses to filter network devices. A switch is a bridge that has multiple ports and is more intelligent. It separates conflicting domains, but creates a large broadcast domain by default. A switch uses hardware addresses to filter network devices. A router separates broadcast domains, and it uses logical addresses to filter network devices.Point out the functions and advantages of a router. Routers are responsible for performing packet switching, filtering, and path selection, and help enable communication in an interconnected network. One advantage that routers bring is a reduction in broadcast traffic.
