Study Notes
Data Communication Essentials
- Sender and Receiver: Devices like computers and telephones act as senders or receivers in communication, relaying messages or data.
- Transmission Medium: Essential for data transfer; it can be guided (e.g., twisted pair cables, fiber optic) or unguided (e.g., radio waves, microwaves) bridging senders and receivers.
- Protocols: Rules governing data communication ensure two devices can communicate effectively, exemplified by Simple Mail Transfer Protocol (SMTP) for email.
Internet and Networking Overview
- Internet: A vast global WAN connecting approximately one million networks across over 200 countries, facilitating seamless data access and communication.
- Intranet vs. Extranet:
- Intranet: Network using Internet protocols for internal communication within an organization.
- Extranet: Connects different organizations' intranets, allowing secure information sharing among business partners.
Components of Data Communication Systems
- Message: Core asset representing the information being communicated; can be text, audio, or video files.
- Sender: Device that transmits data; could be a computer, mobile, or other electronic devices.
- Receiver: Endpoint for the message, mirroring the sender's device types.
- Set of Rules (Protocols): Ensure that communication can occur, establishing compatibility between different devices.
Network Architecture
- Modem: Converts analog signals to digital signals, enabling communication over various media.
- Hub: A basic networking device connecting multiple devices, broadcasting data to all ports indiscriminately.
- Switch: Advanced version of a hub that intelligently sends data to specific ports, reducing network congestion.
- Router: Forwards data packets between networks, allowing different networks to communicate.
Types of Networks
- Personal Area Network (PAN): Connects devices in proximity to an individual, facilitating personal device communication.
- Bandwidth: Measurement of transmission speed in bits per second (bps), determining the data capacity of telecommunications mediums.
Alternative Delivery Channels in Banking
- Core Banking Solutions (CBS): Adopted by banks to enhance service delivery through computer and internet integration.
- Impact on Banking Operations: Networks promote data sharing among employees and enhance teamwork across organizations, essential for modern banking.
Web and Information Caution
- Web Information: While the Web offers extensive data access, quality assurance is lacking; users must exercise caution (User beware!).
Key Learning Points
- Understanding the roles of different components and how they work together is vital in data communication.
- The distinction between internal (Intranet) and inter-organizational (Extranet) networks highlights the importance of secure communications.
- Awareness of potential risks when obtaining information from the Web emphasizes the need for critical evaluation of sources.
