Study Notes
Hardware Communication Protocols
- Different hardware communication protocols enable connectivity, each tailored for specific applications and environments.
- Understanding these protocols is essential for creating effective network designs based on given scenarios.
Network Devices
- Network devices forward messages between resources, determining routing paths within the network.
- Key types include:
- HUB: Connects multiple network devices, broadcasting data to all ports.
- SWITCH: Intelligent device that sends data only to the specific device it is intended for.
- ROUTER: Connects different networks, directing data packets between them.
Types of Communication
- Unicast: A one-to-one communication method.
- Multicast: A one-to-many communication directed to a specific group.
- Broadcast: Sending data to all devices in a network.
- Anycast: Data sent to any one member of a group, closest to the sender.
Types of Servers
- Different servers handle various functions, including:
- Application Server: Hosts applications and provides services.
- Database Server: Stores and manages databases.
- Web Server: Serves web pages to clients.
- DNS Server: Resolves domain names to IP addresses.
- DHCP Server: Assigns IP addresses dynamically.
- FTP Server: Facilitates file transfers.
- Email Server: Manages email services.
- File Server: Centralizes file storage and access.
- Proxy Server: Acts as an intermediary for requests.
- Print Server: Manages printers and print jobs.
- Gaming Server: Supports online gaming applications.
- SSH Server: Provides secure remote access.
Network Media
- Network media refers to the physical mediums through which data is transmitted, including cables and wireless connections.
Network Topology
- The structure of a network, which defines how devices are arranged and how they communicate:
- Includes configurations such as star, ring, bus, and mesh.
Network Classifications
- Networks can be classified based on their scale:
- PAN (Personal Area Network): Very small network, typically within a range of a few meters.
- LAN (Local Area Network): Covers a small geographical area like a home or office.
- CAN (Campus Area Network): Connects multiple LANs within a limited campus.
- WAN (Wide Area Network): Spans large geographical areas, connecting multiple LANs.
- MAN (Metropolitan Area Network): Covers a city or a large campus.
Network Protocols
- Essential protocols for effective data communication include:
- TCP/IP: Fundamental suite used for internet and intranet communications.
- HTTP: Protocol for transmitting web pages.
- FTP: Used for file transfers.
- SMTP: Standard for email transmission.
- SSH: Securely connects to devices remotely.
- NTP (Network Time Protocol): Synchronizes clocks across devices.
TCP/IP
- TCP/IP (Transmission Control Protocol/Internet Protocol) enables connectivity among network devices on the internet and private networks.
- It is foundational for all internet communications.
Network Design Exercise
- A network architecture should be created for a cloud service provider hosting databases and applications, incorporating:
- An API for client-server communication.
- Client devices including mobile and desktop computers.
- Ensure to include necessary protocols and network devices in your design.
- Examples of design concepts could include e-commerce or social media platforms.
