The OSI model is a conceptual framework used to understand network communication in seven layers.
Layer 1: Physical - Deals with the physical connection (e.g., cables, switches).
Layer 2: Data Link - Manages node-to-node data transfer (e.g., Ethernet).
Layer 3: Network - Handles routing of data (e.g., IP addresses).
Layer 4: Transport - Ensures complete data transfer (e.g., TCP, UDP).
Layer 5: Session - Manages session...
FTTP (Fiber to the Premises) delivers fiber optic connections to buildings, while FTTH (Fiber to the Home) specifically targets residential homes.

Example: 'network 192.168.1.0 mask 255.255.255.0' to advertise a specific subnet.
The command must be used in the BGP configuration mode after defining the BGP process.
Routes must be present in the routing table to be advertised.
Understanding traffic flow through OSI layers L1-L4 enhances network troubleshooting and optimization.
L1 (Physical Layer): Deals with the physical connection, e.g., cables, switches, and signals.
L2 (Data Link Layer): Manages node-to-node data transfer, e.g., Ethernet frames and MAC addresses.
L3 (Network Layer): Handles routing and forwarding, e.g., IP addresses and routers determining paths.
L4 (Transport Layer): E...
R and S refer to routing and switching in network design, focusing on data packet management and traffic control.
R (Routing) involves determining the best path for data packets to travel across networks.
S (Switching) refers to the process of directing data packets within a local network.
Example of Routing: OSPF (Open Shortest Path First) is a popular routing protocol.
Example of Switching: VLANs (Virtual Local Area...
ITIL defines three main types of changes: Standard, Normal, and Emergency, each with distinct processes and approval requirements.
Standard Change: Pre-approved changes with low risk, like routine software updates.
Normal Change: Changes that require assessment and approval, such as system upgrades.
Emergency Change: Changes that must be implemented immediately to resolve incidents, like critical security patches.
Change management is a structured approach to managing changes in an organization to minimize disruption and maximize benefits.
Change management involves planning, executing, and monitoring changes to minimize risks.
It includes assessing the impact of changes on IT services and stakeholders.
An example is implementing a new software system, requiring training and support.
Change management processes often follow fra...
