1. What Is the Task State Machine Model? The task state machine model describes the lifecycle and state transitions of a task. Typical states include: (1) Ready: The task can execute but is waiting for the scheduler to allocate CPU. (2) Running: The task is currently using the CPU to execute. (3) Blocked: The task … Read more
(Report Producer/Author: CITIC Securities, Huang Yayuan) Detailed Explanation of Switch Chips: Core Components of Switches, Responsible for Forwarding Functions Switches: The Core Foundation of the Digital Economy A switch is a network device used for forwarding electrical (optical) signals, providing a dedicated telecom signal pathway for any two network nodes connected to it, thus forwarding … Read more
The switch is a very important part of network construction, and some friends have doubts about how to choose a switch. Before choosing a switch, you should first understand how switches are used in networking. This article summarizes the networking methods of switches in four network scenarios and common troubleshooting solutions. 1. Small Network A … Read more
The break statement is a keyword in C language used to exit the execution of loops or switch statements. The break statement is commonly used to terminate a loop early when a certain condition is met, or to exit the switch statement after matching a certain case. There are two common scenarios for using the … Read more
This article will take you through the core concepts of Real-Time Operating Systems (RTOS) in a straightforward manner, gradually guiding you to create a small yet fully functional RTOS. We will cover the basic components of RTOS, task scheduling, portability, and task synchronization mechanisms. 1. Basic Components of RTOS A minimal RTOS typically includes the … Read more
Two days ago, the weak current industry network published several networking methods for monitoring systems. Some friends asked what type of switch is suitable for 600 monitoring points? For 200 monitoring points, how to choose a switch? How to network, etc.? Before choosing a switch, I need to understand the project’s networking framework. Once the … Read more
Due to length, the second solution is presented separately. Compared to the previous plan, this one focuses on cost-effectiveness. This solution can be implemented without replacing the optical modem based on existing equipment, or by replacing the optical modem. However, the impact of the optical-to-electrical conversion at the source is minimal. The main concern is … Read more
