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.
