What is primary key?
A primary key is a special type of data column in a database table that is used to uniquely identify each row of data in the table. It is used to ensure data integrity and to guarantee that no two rows of data in the same table have the same key. The primary key is often referred to as the "identifier" of the table and is typically created as an auto-incrementing integer. The primary key is used to ensure data accuracy and to prevent data duplication in the table. It is also used to link the data in the table to other data in the database.

you deployed an app engine application using gcloud app deploy, but it did not deploy to the intended project. you want to find out why this happened and where the application deployed. what should you do?
You should examine project settings and the app.yaml file for your application. To check the gCloud configuration used for app deploy, open Cloud Shell and execute gcloud config list.
Your deployment was rolled back since you weren't able to get well in the allowed period. If you think this was a mistake, consider modifying the readiness check section's app start timeout sec setting.
Verify that the app start timeout sec value is present in the readiness check section of your app.yaml file. If it doesn't already exist, create it and increase the app start timeout sec value from the default 300 seconds.
Before deploying, you must add the endpoints API service section to app.yaml during configuration. To receive the configuration for your service, the Extensible Service Proxy (ESP) requires the settings that you specify in this section.
The rollout strategy: managed option or a configuration ID must be entered in the config id field, but not both. This setting tells ESP to utilize the most recent service configuration that has been deployed. When you choose this option, ESP automatically recognizes the change and starts utilizing it up to five minutes after you deploy a new service configuration. We make a change and use it immediately after. Instead of providing ESP with a specific configuration ID, we advise using this option.

A VME can be provided using the virtualization technique known as full virtualization, which entirely simulates the underlying hardware. Any software that can operate on the physical hardware can be used in this kind of environment, and each individual VM can run any OS that is supported by the underlying hardware. Users are able to run many guest operating systems at once.
Full virtualization is useful in many situations. For instance, in the development of operating systems, experimental new code can run concurrently with older versions, each in a different VM. Each virtual machine (VM) is given access to all of the real system's features, including a virtual BIOS, virtual peripherals, and virtualized memory management, by the hypervisor.

A hardware word is the term used to describe the greatest address size that can be used to identify a location in memory. As a result, although your CPU can address 64KB (216), it can only send 8 bits at a time. A CPU might promote a 16-bit bus (for this purpose). In its instructions, it employs 16-bit addresses, and, like your example, it has 64 ki. However, it has a 16-bit data bus and a 15-bit address bus. It simply requires 32 Ki addresses, and each location always provides 2 bytes.
