With that ZIP only you will not be able to achieve that.

Because within the bin folder, the ng still needs some dependencies.

In order to do that:

• Download the zip from the official repo: https://github.com/angular/angular-cli/archive/master.zip
• Unzip it and go into that folder
• Run npm install or yarn
• Zip the whole folder again

Now you'll be able to run the CLI on an offline computer if you share that zip by doing:
- Unzip the CLI folder with the node_modules in it
- /path/to/the/folder/bin/ng new my-project

BUT. As this computer is offline, you'll only be able to scaffold a new project without installing it's required dependencies.

Now, if you want to build a project on that offline computer, you'll need something more:

On the online computer:
- install @angular/cli yarn global add @angular/cli (or use your zip)
- create a new empty project while online: ng new base-project
(wait for yarn install or npm install to finish)
- zip the node_modules folder, the one within the new project
(as node_modules_backup.zip for ex, and brace yourself... It's going to take a long time I guess)

On the offline computer
- Share the ZIP from the new project (with USB for ex) - Create your project: /path/to/the/folder/bin/ng new my-project --skip-install
- Unzip the node_modules_backup.zip into the newly created project

Now running /path/to/the/folder/bin/ng serve should work.

----online machine-----

1. Install node by using the executable files downloaded from the official node website.
2. Install the @angular/cli globally on the on-line machine.
3. Check the C:\Users\Admin\AppData\Roaming folder.
4. Zip the npm and npm_cache folder.
5. Transfer the above zip file and node executable to the offline machine.
6. Create the new project in angular
7. zip the node_module folder inside the created project and transfer it to the offline machine.

----Offline Machine------

9. Install node from its executable
10. Unzip the npm and npm_cache folder and move it to the C:\Users\Admin\AppData\Roaming folder.
11. Run the following command to install the @angular/cli and its dependencies

npm i @angular/cli -g --cache MY_CACHE_FOLDER --cache-min 999999999 --no-shrinkwrap

12. Now create the new angular project. It will show some errors but don't worry.
13. Unzip and move the node_module folder inside the new project.
14. Now, you can work/run on the project as usual.

This would be a good solution for your case.

npm i @angular/cli -g --cache MY_CACHE_FOLDER --cache-min 999999999 --no-shrinkwrap
