Study Notes
Network Protocols: Introduction
- Networks connect computers for communication and resource sharing, similar to a community. This allows for file, printer, and internet sharing, messaging, and collaborative projects across locations.
- Protocols are sets of rules that ensure smooth operation, like a recipe or a game with defined steps.
- Network protocols standardize how data is transmitted, received, and processed. This ensures interoperability across various hardware and software platforms.
Key Network Protocols
- Transmission Control Protocol (TCP): Ensures reliable, ordered delivery of data (e.g., web browsing, email, file transfer).
- Internet Protocol (IP): Addresses and routes data packets crucial for internet communication.
- Hypertext Transfer Protocol (HTTP): Transfers web pages between servers and browsers.
- File Transfer Protocol (FTP): Transfers files between computers.
- Simple Mail Transfer Protocol (SMTP), Post Office Protocol (POP3)/Internet Message Access Protocol (IMAP): Manage email communication (sending/receiving).
- Domain Name System (DNS): Translates domain names (e.g., www.example.com) to IP addresses.
- Dynamic Host Configuration Protocol (DHCP): Automatically assigns IP addresses.
- Secure Shell (SSH) and Telnet: Provide secure or unencrypted remote access to servers.
- Simple Network Management Protocol (SNMP): Allows network management and monitoring.
- Hyper Text Transfer Protocol Secure (HTTPS): Secure web browsing with SSL/TLS encryption.
Managing Network Protocol Services
- Selecting a protocol depends on the specific network needs (e.g., web browsing uses HTTP/HTTPS).
- Testing protocols involves functionality, performance, security, compatibility, reliability, stability, scalability, usability, error handling/recovery, and interoperability checks. Aligning with documentation review is critical.
- Validating protocol service confirms compliance with predetermined standards, performs functional checks, assesses performance under varied conditions, validates security measures, and verifies compatibility among devices and protocols.
Designing a Network Address System
- Designing addresses involves defining IP schemes, subnetting, and addressing assignment based on network requirements (number of devices, growth plans, security needs, regulations).
- Choose IP version (IPv4 or IPv6). IPv6 provides substantially more address space than IPv4.
- Consider private IP address ranges (e.g., 10.x.x.x, 172.16.x.x, 192.168.x.x) for internal networks.
- Implement subnetting for improved efficiency, security, and manageability.
- Plan usage of VLANs and DHCP for increased handling of organizational or physical location segmentation.
IP Addresses
- IPv4: 32-bit addresses, widely used, represented in dotted-decimal format (e.g., 192.168.1.1).
- IPv6: 128-bit addresses, represented in hexadecimal format (e.g., 2001:0db8::1).
- Types: Public (globally unique), Private (reserved for internal use), Static (fixed), Dynamic (automatically assigned).
Configuring and Testing IP Addresses
- Windows configuration involves selecting network adapter properties, choosing TCP/IPv4 settings, specifying the IP address, subnet mask, default gateway, and DNS server, and saving changes.
- Testing involves checking IP configuration via
ipconfigand using thepingcommand to test connectivity to default gateways, remote devices, and external IP addresses (e.g., 8.8.8.8). - Check DNS resolution.
