Study Notes

File and Resource Sharing

  • Enables data sharing between users and remote access via connected devices.
  • Resource sharing involves making computer resources available to other hosts on a network, including storage devices and printers.
  • Sharing a single internet connection is cost-efficient and enhances system protection when secured properly.

Computer Networks

  • Cost savings can be achieved by reducing transaction costs over time.
  • Increased storage capacity allows access to files and multimedia stored remotely.
  • Web technologies have led to new business models, including e-commerce and online advertising.

Network Protocol Stack

  • Client and Server communicate using identical protocols: HTTP, TCP, IP, and Ethernet.

Network Protocols

  • SMTP (Simple Mail Transfer Protocol): Standard protocol for email services on a TCP/IP network, enabling sending and receiving emails.
  • DNS (Domain Name System): Hierarchical naming system that translates human-readable addresses into machine-readable IP addresses.
  • RIP (Routing Information Protocol): Dynamic routing protocol using hop count for determining the best path between networks.

Basic Concepts

  • Universal Addressing: Enables unique identification of computers via IP addresses.
  • TCP/IP: Standardized set of rules for computer communication over networks.
  • DNS: Facilitates website discovery using human-readable addresses.

Universal Processing Protocols

  • URL (Uniform Resource Locator): Address for accessing web resources.
  • HTTP (Hypertext Transfer Protocol): Protocol for transferring hypertext.
  • HTTPS (Hypertext Transfer Protocol Secure): Secure version of HTTP.
  • HTML (Hypertext Markup Language): Language for structuring web pages.
  • FTP (File Transfer Protocol): Protocol for transferring files over the internet.
  • Hypertext supports multimedia elements like text, images, and sounds.

Client/Server Model

  • A distributed structure where tasks are shared between servers providing resources and clients requesting services.

Internet Technologies & WWW Architecture

  • Interaction involves clients making requests via browsers and servers responding with the requested data over TCP/IP.

Computer Networks Overview

  • Defined as interconnected independent computers, forming a network that supports communication.

E-Commerce Course Focus

  • Covers electronic commerce applications, technologies, and tools for business on the World Wide Web.
  • Discusses foundations, infrastructure, and models: B2C, C2B, B2B, and C2C transactions.
  • Addresses security threats in online business and mitigation strategies, including secure credential services and electronic payment systems.

Traditional vs. E-Commerce

  • Commerce involves a negotiation between buyers and sellers, incorporating distinct activities known as business processes.
  • E-commerce is defined as the use of electronic data transmission to facilitate business activities, such as sending purchase orders and invoices electronically.

Key Properties of the Internet

  • The Internet's interoperability allows any connected computer to communicate with any other, creating a global network of accessibility.
