Study Notes
Network Protocols
- Network protocols define how messages are exchanged between source and destination.
- Standards are important for developing and implementing protocols because they allow products from different manufacturers to interoperate successfully.
OSI Model Layers
- The Application layer of the OSI model is similar to the Application layer of the TCP/IP model.
- The Presentation and Session layers of the OSI model are also similar to the Application layer of the TCP/IP model.
- An IP address is encapsulated at the Network layer of the OSI model.
TCP/IP Model
- The Transport layer of the TCP/IP model processes segments.
- Layer 4 of the OSI model is responsible for describing the ordered and reliable delivery of data between source and destination.
- A protocol data unit (PDU) is a general term for a piece of data at any layer of a networking model.
Network Devices
- A router determines the path that messages should take through internetworks.
- End devices originate data that flows through the network.
- Intermediary devices connect individual hosts to the network.
Network Types
- An intranet is a private network used within a company or organization.
- The Internet is a global network that connects computers and networks worldwide.
- An extranet allows authorized outside users access to a company's internal network.
- A local area network (LAN) connects computers and devices within a limited geographical area.
Network Trends
- Bring Your Own Device (BYOD) allows employees to use their personal devices to access resources on a business or campus network.
- Converged networks deliver data, voice, and video over the same network infrastructure.
- Cloud computing allows applications to be accessed over the Internet by any device, anywhere in the world.
- Powerline networking uses existing electrical wiring to extend an existing home LAN.
Network Security
- Implementing a firewall and antivirus software offer minimal security requirements for a small office network.
- Quality of Service (QoS) is required for network traffic that needs priority, like video conferencing.
Network Scalability
- A scalable network can grow in size without impacting existing users.
Network Communication
- Broadcast communication sends a message to all devices on a local area network.
- Encapsulation is the process of placing one message inside another message for transfer.
Protocol Stack
- The correct order of the protocol stack used to prepare a web request for transmission from the client's perspective is: HTTP, TCP, IP, Ethernet.
