Study Notes
Computer Network & Security - CPE 8
- Networking involves data exchange between devices or nodes on a network.
- Devices include computers, servers, smartphones, IoT devices, and more.
- Data transmission uses various mediums like copper cables, fiber optics, or wireless signals.
- Protocols standardize data packaging, addressing, and delivery.
Networking Concepts
- Key Concepts: Network Topology (physical/logical layout of devices), Network Protocols (rules for data format, transmission, and receipt).
- Common topologies include bus, star, ring, mesh, and tree.
- Common protocols include TCP/IP, HTTP, FTP, and SMTP.
OSI Model
- A conceptual framework that standardizes networking system functions into seven layers. Each layer has specific responsibilities and protocols.
- Layers (from top to bottom): Application, Presentation, Session, Transport, Network, Data Link, Physical.
- The Application layer interacts with end-users, e.g., web browsers, email.
- Layer 6 (Presentation) ensures incoming data is presentable to the user.
- Session Layer facilitates establishing and terminating connections.
- Transport layer handles reliable data transmission and error checking.
- Network Layer routes data through networks.
- Data Link layer receives and transmits packets of data.
- Physical Layer involves physical network components (cables, routers).
History of Networking
- Early networking focused on Local Area Networks (LANs) like Ethernet.
- The World Wide Web (WWW) made the internet more accessible through the invention of web browsers and HTML.
- Wireless technologies, mobile devices, and the Internet of Things (IoT) gained prominence.
- Cloud computing, edge computing, and software-defined networking (SDN) emerged.
IP Addressing and Network Security
- IP Addressing: Each device has a unique identifier for routing data. Versions include IPv4 and IPv6.
- Network Security is essential to protect data confidentiality, integrity, and availability. Measures include firewalls, encryption, and access control.
