Study Notes
OSI/RM Layers and Protocols
- The header contains OSI/RM layer information.
- Internet Protocol (IP) operates at the Network layer.
- The Session layer manages how protocols establish and tear down connections.
- The Application layer serves as the user interface in networking environments.
- Transmission Control Protocol (TCP) is the primary protocol at the transport layer of OSI/RM.
Network Devices and Architectures
- A router or a switch is essential for creating and connecting Wide Area Networks (WANs).
- Local Area Networks (LANs) consist of computers within a confined geographic area for sharing data and resources.
- In a server-based network, nodes dedicate resources to assist other hosts.
- In star topology, network nodes connect through a central device, usually a hub or switch.
Data Handling and Management
- Business logic refers to the coding necessary for establishing relationships in databases, typically in SQL.
- In a packet, the original data is termed the payload.
- The Cyclical Redundancy Check (CRC) ensures packet validity in packet-based networks.
Network Functionality and Services
- Voice over IP (VoIP) networks allow voice calls over packet-switched TCP/IP networks.
- An Internet Service Provider (ISP) maintains gateways to the internet and rents customer access.
- An Internet Exchange Point (IXP) acts as a junction for high-speed backbones.
Networking Protocols and Technologies
- All email protocols utilize TCP for functionality.
- Stateless protocols operate on a "best-effort" basis, sending information without guaranteed delivery.
- Unified communications (UC) enables the conversion of voice to text and vice versa.
Security and Operations
- A Network Operations Center (NOC) manages and monitors network resources, often equipped with multiple redundant connections.
- A NoSQL database is ideal for storing massive amounts of unstructured data that traditional relational databases cannot handle.
Communication Principles
- Interoperability is the ability of systems from different vendors to communicate effectively.
- Presencing allows devices to track and report user location and availability.
Network Basics
- All networks consist of three elements: protocols, transmission media, and network services.
- The network's physical layer handles the transmission of unstructured bit streams.
Miscellaneous
- A computer shell is a command-based interface for user commands.
- A mesh topology provides multiple paths between nodes for redundancy.
- Cloud computing allows access to software and services over the internet without local installation.
