English Class for Laboratory Members
(Informal Teaching)
Overview:
This informal class was designed to support ISEC Laboratory members in improving their English communication skills, with a focus on practical conversation and technical vocabulary relevant to research activities, especially for academic presentations. The sessions combined short learning materials with active practice, including individual speaking exercises, small‑group discussions, and guided conversation drills. Participants also used ChatGPT as an additional practice partner, allowing them to simulate real-time dialogue and improve fluency outside class sessions. My role included preparing materials, facilitating discussions, and supporting members in building confidence when presenting or communicating in academic activities.

Data Communication & Computer Network
Overview:
This course introduces the core principles of data communication and computer networking, including transmission methods, network architectures, and communication protocols. Students explore how data flows across different network layers and analyze the performance of communication systems. Practical learning is supported through Cisco Packet Tracer, allowing students to simulate network behavior, configure devices, and visualize data transmission in a controlled environment.
Computer Network Management
Overview:
This course focuses on the administration, monitoring, and optimization of computer networks. Students learn about network management frameworks, configuration strategies, performance analysis, and troubleshooting techniques. The course emphasizes hands-on experience using VirtualBox virtualization, enabling students to build and manage multi‑node virtual network environments that mirror real-world infrastructure scenarios.
Computer Security
Overview:
This course provides foundational knowledge of computer and network security, covering topics such as threat identification, cryptography basics, secure system configuration, and common vulnerabilities. Students practice essential security techniques using Linux-based operating systems, including basic security commands, OpenSSL utilities, and other standard security tools. Lab activities and evaluations focus on applying defensive measures and understanding practical security workflows.
Computer Network System
Overview:
This course covers essential concepts of network systems, including network topologies, routing, switching, and device configuration. Students learn how different components interact to form functional network infrastructures. Practical sessions use Cisco Packet Tracer to simulate network setups, configure devices, and test system behavior, helping students build strong applied skills in network system implementation.
