1. What is the representation of negative numbers and why is it so designed?Negative numbers are expressed in the form of a positive complement, that is, after conversion to binary, you take the counter plus 1.And the first symbol, 1 is a negative number, 0 is a positive number.In this way, the absolute value equals the plus or minus two number, the sum can overflow the highest bit, and the result is 0.How is 2.-128 stored in memory? The calculation process?In bytes of byte type, the range of th

Learn how to create AWS LAMBDA functions This execute on a scheduled interval and much like a cron job would. In this lesson we'll create a LAMBDA function that checks for a string of text on a website to verify the website are up and operational. The lambda function logs to CloudWatch Metrics and sends a notification e-mail using an SNS queue if the check fails.Create a lambda function: (WebTest)Exports.handler =function(event, context) {varHTTP = require (' http '); varOptions ={host:' Statics
