OSI network model has 7 layers. Layer 2 is Data Link layer and Layer 3 is Network layer.
Layer 2 protocols include Ethernet, Wi-Fi, and PPP
Layer 3 protocols include IP, ICMP, and ARP
Data Link layer provides error-free transmission over physical layer
Network layer provides logical addressing and routing of data packets
Layer 2 devices operate at the data link layer, while Layer 3 devices operate at the network layer.
Layer 2 devices include switches and bridges.
Layer 3 devices include routers and layer 3 switches.
Layer 2 devices forward frames based on MAC addresses.
Layer 3 devices forward packets based on IP addresses.
Routers direct traffic between networks while switches connect devices within a network.
Routers use IP addresses to direct traffic between networks
Routers can prioritize traffic based on Quality of Service (QoS)
Switches use MAC addresses to connect devices within a network
Switches can create virtual LANs (VLANs) to segment a network
Example of a router: Cisco ISR 4000 series
Example of a switch: Cisco Catalyst 2960 serie
OSI has 7 layers while TCP/IP has 4 layers.
OSI model is theoretical while TCP/IP is practical
OSI has a dedicated session layer while TCP/IP does not
TCP/IP combines the presentation and session layers into one
OSI is more complex and rarely used in practice
TCP/IP is the standard for internet communication

Process scheduling is the method by which the operating system decides which process to run first.
Process scheduling is an important part of operating system design.
It involves deciding which process to run first, based on various criteria such as priority, time slice, and resource availability.
There are several scheduling algorithms, including First-Come-First-Serve (FCFS), Round Robin, and Priority Scheduling.
