## Basic computing skills

### Using your operating system's command line interface (aka "shell", "terminal", "CLI")

You should be able to open a command line window (Windows: cmd.exe, Mac: Terminal) and perform basic operations such as navigating, creating and removing folders, and passing optional arguments to common commands like cd, ls, copy, top, kill and others.

If the above is gibberish to you, I highly recommend you do one of the tutorials below:

• more extensive tutorial that works on Mac and Windows PowerShell (see note below)

If you already know how to use the Windows command prompt, you can consider using a fuller-featured shell such as PowerShell if you aren't already.

### Using FTP to transfer files

Large data sets are usually stored on servers that cannot be accessed using a Web browser; they instead use FTP. It's easy, but if you've never used a FTP client like FileZilla before, this tutorial may be helpful.

### Handling compressed files (archives)

Neural data sets are often highly compressible. Compressing files into flie formats such as .zip or .rar can save space and speed up data transfer times. To handle compression and decompression on Windows, I recommend WinRAR.

### Choosing appropriate graphics file formats

Know the difference between lossless and lossy image (bitmap) formats, and the difference between bitmap and vector graphics formats.
