OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven abstraction layers.

• OSI model divides network communication into seven layers

• Each layer has specific functions and interacts with adjacent layers

• Layers include physical, data link, network, transport, session, presentation, and application

• Example: Sending an email invol...read more

Routing protocol is a set of rules used by routers to determine the best path for data packets to reach their destination.

• Routing protocols help routers communicate with each other to share information about network topology.

• They determine the optimal path for data packets based on factors like network congestion, speed, and cost.

• Examples of routing protocols include RIP (Routing Information Protocol), OSPF (Open Short...read more

Spanning Tree Protocol is a network protocol that ensures a loop-free topology in Ethernet networks.

• Prevents loops in Ethernet networks by blocking redundant paths

• Designated switches are elected as root bridge

• Uses Bridge Protocol Data Units (BPDUs) for communication

• Common variants include STP, RSTP, and MSTP

OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.

• OSI model helps in understanding how different networking protocols work together.

• Each layer in the OSI model has specific functions and communicates with adjacent layers.

• Examples of OSI layers include Physical layer, Data Link layer, Network layer, Transport la...read more

OSPF is a link-state routing protocol while BGP is a path vector routing protocol.

• OSPF is used within an autonomous system, while BGP is used between autonomous systems.

• OSPF calculates the shortest path based on link cost, while BGP selects the best path based on policies and attributes.

• OSPF uses Dijkstra's algorithm for route calculation, while BGP uses the path vector algorithm.

• OSPF is typically used in internal netw...read more

A network is a collection of interconnected devices that communicate and share resources, enabling data exchange and collaboration.

• Types of networks include LAN (Local Area Network), WAN (Wide Area Network), and MAN (Metropolitan Area Network).

• LAN connects devices in a limited area, like a home or office; for example, Wi-Fi networks.

• WAN connects larger geographical areas, such as the internet, linking multiple LANs.

• Net...read more

A Local Area Network (LAN) connects computers and devices within a limited area, enabling communication and resource sharing.

• LANs typically cover small geographic areas like homes, offices, or buildings.

• They allow devices to share resources such as printers and files.

• Common LAN technologies include Ethernet and Wi-Fi.

• An example of a LAN is a home network connecting computers, smartphones, and smart TVs.

A CI/CD pipeline automates the software development process, enabling continuous integration and delivery for faster releases.

• Continuous Integration (CI) involves automatically testing and merging code changes from multiple contributors.

• Continuous Delivery (CD) ensures that code changes are automatically prepared for release to production.

• The pipeline typically includes stages like code commit, build, test, and deploym...read more

Testing is the process of evaluating a system or its component(s) with the intent to find whether it satisfies the specified requirements or not.

• Testing is done to ensure that the software meets the requirements and works as expected.

• It involves executing a system or its component(s) with the intent of finding errors or defects.

• Testing can be done at various stages of the software development life cycle such as unit te...read more
