Networked systems are groups of computers or devices that communicate with each other to share information and resources. They rely on rules called protocols, like HTTP and TCP, to make sure data is sent and received properly. One important lesson is that networks are not always reliable, so systems must be designed to handle delays, failures, and security risks. As systems grow, they need to be scalable and fault-tolerant to keep working even when traffic increases or parts fail. Overall, understanding network systems helps us build applications that are efficient, secure, and able to serve many users at the same time.

I learned about Single Processor Systems is that system performance will depends on how single processor system match the workload requirements. Single-core processor system is best fit for sequential tasks due to the straightforward execution flow. On the other hand, task than are can be divided or performed separately, the multi-core processor will be the best for this. This will improve speed and efficiency through parallel processing.

I am an accomplished public sector IT executive with extensive experience leading enterprise digital transformation, cybersecurity governance, and large-scale systems modernization initiatives. As Head of System Development, I drive the strategic design, implementation, and institutionalization of mission-critical ICT systems that power payroll, business permitting, and among others citywide operations.

I established structured System Development Policies and Procedures (SDPP), implemented centralized and encrypted database architecture, and strengthened cybersecurity frameworks through enterprise firewall, endpoint protection, and cloud security monitoring solutions. Serving as the Overall Compliance Officer for IT (Data Privacy and Cybersecurity), I ensure regulatory compliance, data protection, and resilient digital infrastructure.

With expertise spanning systems architecture, cloud governance, application supervision, and enterprise integration, I am committed to building secure, scalable, and citizen-centered digital ecosystems that enhance transparency, operational efficiency, and public service delivery.
