To install Go on your computer, you can follow these steps:
- Visit the official Go website (https://golang.org/dl/) using your preferred web browser.
- Download the Go binary for your operating system. Make sure to select the appropriate binary based on your operating system and architecture (32-bit or 64-bit).
- Once the download is complete, locate the downloaded file and double-click on it to open the installer.
- Follow the instructions provided by the installer to complete the installation process. Make sure to choose the desired installation location and options if prompted.
- After the installation is finished, you may need to set up some environment variables. These variables include "GOROOT," specifying the installation directory of Go, and "GOPATH," defining the workspace directory for your Go projects. Consult the Go documentation specific to your operating system for detailed instructions on setting up these environment variables.
- Verify the installation by opening a new terminal or command prompt window and typing "go version" without quotes. If Go is successfully installed, it will display the installed version of Go.
Congratulations! You have now successfully installed Go on your computer. You can start writing and running Go programs by using a text editor and running the Go commands in the terminal or command prompt.

What is the difference between Go installation and Go workspace?
The Go installation and Go workspace are two different concepts in Go programming.
- Go Installation: This refers to the process of installing the Go programming language on a system. When you install Go, you download a distribution archive or use a package manager to install the necessary binaries and files to run the Go compiler and tools. The Go installation provides the compiler (go command) and other standard tools like gofmt, go test, etc. necessary for building and running Go programs.
- Go Workspace: A Go workspace is a directory structure where Go code, packages, and dependencies are organized. It typically consists of three main directories: src: This directory contains the source code files of Go packages and programs. Each subdirectory within src represents a separate package. bin: After building Go programs, the executable files are stored in this directory. pkg: The compiled package files (.a files) are stored in this directory.
The workspace is a fundamental part of Go development and helps manage dependencies, build and install packages, and facilitate a modular approach to code organization. It also includes the GOPATH environment variable, which indicates the root directory of the workspace.
In summary, the Go installation is the process of installing the Go binaries and tools, while the Go workspace is the directory structure where Go code is organized and managed.
