Polling vs Interrupt-Driven I/O: What Is the Difference?
Polling is where the CPU repeatedly checks a device’s status register in a loop until it is ready, while interrupt-driven I/O lets the CPU do other work and re…
Push vs Pull Architecture: What Is the Difference?
In a push architecture the producer actively sends data to consumers as soon as it is available, while in a pull architecture consumers periodically request or…
Polling vs Webhooks: When Should You Use Each?
Polling has a client repeatedly ask a server “is there anything new?” on a fixed interval, while a webhook has the server call a URL the client registered in a…
