Study Notes

Introduction to Networking

Good notebook promotes learning experience.

Network Development

Computer Network: Connects two or more devices to communicate and share ideas; either wireless or wired.
Shared Resources: Examples include data, printers, faxes, and email systems.
Primary Network Elements: Resources (shared items), pathway (transmission medium), and protocol (rules governing communication between computers).
Primary Benefits of Networking: Resource sharing, communication (email, messaging, conferencing), centralized management (simplifying user control, backups, updates), cost-efficiency (lowering equipment and maintenance costs), flexibility (allowing remote access and scalability), data security (protecting information through controlled access and monitoring), enhanced collaboration (facilitating teamwork via shared tools and platforms), increased productivity (boosting efficiency through faster access and streamlined processes).
Disadvantages of Networking: High initial costs of hardware, software, and maintenance; security risks (vulnerability to cyberattacks, malware, and breaches); technical complexity for management and troubleshooting; dependency on the network for connected systems; performance issues (due to heavy traffic or poor design); privacy concerns (shared resources and data increasing unauthorized access risk); maintenance needs (updates and monitoring demands time and resources).
Standalone Computer: A computer that operates independently of other computers in a network.
Packet Switching: Breaks data into smaller packets for efficient transfer across networks. Network devices route these packets to the final destination where the receiving device reassembles them.

Modems vs. Routers

Modem: Connects a home to the internet,translates internet signals from the provider, typically connects to one device (or a router).obtains a public IP address from the internet service provider. No built-in security.
Router: Shares internet access with all devices, creates Wi-Fi and connects multiple devices.Connects to many devices, assigns local IP addresses, adds a firewall to protect network.

Network Switches

Network Switch: Connects devices (like computers or printers) on a network, facilitating communication between them; sends data directly to the intended device.

Important Definitions

Server: A computer providing resources, services, or data to other computers (clients).
Client: A device requesting resources or services from a server.
Peer: A device in a peer-to-peer network that can both provide and request resources and services.

Peer-to-Peer vs. Client-Server Networks

Peer-to-Peer (P2P): Network without a dedicated server. Each computer shares its resources and acts as both client and server. Typically involves a small number of computers (under 20). Less security concerns, easier setup, and less costly.
Client-Server: Network with a central server managing resources. Centralized control and management, better security, scalable, centralized data backup, and easier resource sharing. More expensive, but with potential for higher reliability and performance.

Centralized vs. Distributed Computing

Centralized Computing: All data and processing occur on a central server.
Distributed Computing: Processing and data are spread across multiple computers.
Parallel Computing: Multiple processors within a single computer work together on a task simultaneously.

Network Plan Steps

Review existing infrastructure and technologies.
Identify appropriate infrastructure and requirements.
Document network design for reference.

Specialized Servers

Application Server: Makes server-side of client/server applications available to clients.
File Server: Provides networked file storage and retrieval services.
Print Server: Connects devices to the network, queues print requests.
Mail Server: Manages email messages.
Database Server: Provides database services through a client/server model.
Web Server: Stores website components and provides access to them.
Name Server: Resolves domain names to IP addresses.

Network Topologies

Bus Topology: All devices connected to a single cable. If one part of the cable fails, it affects the entire network. Easy setup, low cost for smaller systems.
Star Topology: Each device connects to a central hub or switch. Failure in one part does not affect other parts. Reliable, manageable, and scalable.
Ring Topology: Each device connects to two other devices through a circular path. Data flows in a single direction. Good for controlling data flow; token passing can help.

DHCP and IP Addressing

DHCP (Dynamic Host Configuration Protocol): Automatically assigns IP addresses to devices; simplifies device connection.
IP Address: A unique 32-bit number identifying a device on a network.
Subnet Mask: Defines the network and host portions of an IP address.
DNS (Domain Name System): Translates domain names into IP addresses.

Transmission Medium

UTP (Unshielded Twisted Pair): Commonly used for LANs; short distances; less expensive.
STP (Shielded Twisted Pair): Suitable for high-interference environments; longer distances; more expensive.
Coaxial Cable: For long distances; often used for cable internet and TV.
Fiber Optic Cable: Very high-speed; long distances; resistant to interference.

OSI and DoD Network Models

OSI (Open Systems Interconnection): Theoretical model defining how networking hardware and software interact. Seven layers define how data flows through a network.
DoD (Department of Defense): Network model used by the US Department of Defense.
