Data Communications Overview
- Data communications involve the exchange of information between devices using transmission mediums like wire cables.
- Key attributes of effective data communication include:
- Delivery to intended recipients.
- Accuracy of transmitted data.
- Timeliness of communication.
- Jitter, or uneven delays in streaming data.
Components & Trends in Data Communications
- Main components include:
- Data flow (simplex, half-duplex, full-duplex)
- Addressing, routing, and signal generation
- Trends driving changes:
- Rapid traffic growth and technological advancements.
- Internet of Things (IoT) expanding service requirements.
- Growth of high-speed LANs and corporate WAN needs.
Networking Technologies
- Increased reliance on:
- High-speed LANs for centralized computing and server farms.
- WANs to accommodate growing telecommuting and data-intensive applications.
- Digital electronics and improvements in bandwidth efficiency.
Networking Models and Communication Tasks
- The communications model consists of processes for data generation, encoding, transmission, and decoding.
- Key tasks in communication include signal generation, message formatting, error detection/correction, and network management.
Transmission Media
- Selection criteria depend on business needs and link distances.
- Advances in technology favor fiber optic and wireless options.
- Cost efficiency remains a priority despite high transmission costs.
Networking Basics
- A network comprises interconnected devices (nodes) capable of data generation, sending, and receiving.
- Network evaluation criteria include performance (transit time, response time), reliability, and security.
Types of Networks
- Local Area Networks (LAN): smaller scope, owned by users, high data rates (e.g., Ethernet).
- Wide Area Networks (WAN): larger geographical spans relying on public circuits, employing technologies like circuit switching, packet switching, and asynchronous transfer mode (ATM).
- Metropolitan Area Networks (MAN): bridges the gap between LAN and WAN, offering high speeds across larger areas.
Switching Techniques
- Circuit switching: Establishes a dedicated communication path, e.g., traditional phone networks.
- Packet switching: Sends data in packets to be routed independently; efficient for computer-to-computer communication.
- Frame Relay: Enhances packet switching, reduces overhead errors, and increases speed.
- ATM: Evolves from Frame Relay, uses fixed-length packets (cells), supports higher speed data transfer with minimal error control overhead.
