Quality of Service (QoS) is a set of techniques and technologies that are designed to optimize the performance of an organization’s network. This technology can help to ensure that high-priority and performance-sensitive applications are capable of continuing to operate effectively even with limited bandwidth and high network congestion. QoS functionality can be integrated into network solutions, such as an organization’s network firewall.

Dynamic routing is a networking technique that provides optimal data routing. Unlike static routing, dynamic routing enables routers to select paths according to real-time logical network layout changes.
Dynamic routing uses multiple algorithms and protocols. The most popular are Routing Information Protocol (RIP) and Open Shortest Path First (OSPF).
Dynamic routing protocols allow routers to share information about the network with other routers to allow them to select the best path to reach a destination.
Details about each protocol will be posted in a while.

For OSPF operation, firstly OSPF Neighborship in other words OSPF Adjacency is established between OSPF routers. To do this, these OSPF routers must be on the same link. Beside being in the same link, these routers need to use some messages and folllow some steps for this neighborship.
These steps are calles OSPF States. (Details in comment)

Key Difference Between TCP/IP and OSI Model
• OSI has 7 layers, whereas TCP/IP has 4 layers.
• The OSI Model is a logical and conceptual model that defines network communication used by systems open to interconnection and communication with other systems. On the other hand, TCP/IP helps you to determine how a specific computer should be connected to the internet and how you can be transmitted between them.
• OSI header is 5 bytes, whereas TCP/IP header size is 20 bytes.
• OSI refers to Open Systems Interconnection, whereas TCP/IP refers to Transmission Control Protocol.
• OSI follows a vertical approach, whereas TCP/IP follows a horizontal approach.
• OSI model, the transport layer, is only connection-oriented, whereas the TCP/IP model is both connection-oriented and connectionless.

Optical Fiber Connectors
An optical fiber connector joins optical fibers, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all, about 100 different types of fiber optic connectors have been introduced to the market.

IPv6 addresses are 128-bits long and are identifiers for individual interfaces and sets of interfaces.
IPv6 addresses of all types are assigned to interfaces, not nodes (hosts and routers). Because each interface belongs to a single node, any of that node's interfaces' unicast addresses can be used as an identifier for the node.
A single interface can be assigned multiple IPv6 addresses of any type.
