ASCII: The Foundation of Text

ASCII (American Standard Code for Information Interchange) maps 128 characters to numbers 0-127. It's the foundation every text encoding builds on. Even UTF-8 is backward-compatible with ASCII for the first 128 code points.

When You Need ASCII Values

  • Working with binary protocols or file formats
  • Understanding control characters (tab=9, newline=10, carriage return=13)
  • Debugging encoding issues
  • Writing character validation logic
  • Understanding URL encoding (%20 = space = ASCII 32)

Key ASCII Ranges

  • 0-31: Control characters (non-printable)
  • 32: Space
  • 48-57: Digits 0-9
  • 65-90: Uppercase A-Z
  • 97-122: Lowercase a-z
  • 127: DEL

MIME Types: Content-Type for the Web

MIME (Multipurpose Internet Mail Extensions) types tell browsers how to handle files. Every HTTP response includes a Content-Type header with a MIME type.

Common MIME Types

  • text/html — HTML pages
  • application/json — JSON data
  • text/css — stylesheets
  • application/javascript — JavaScript
  • image/png, image/jpeg, image/svg+xml — images
  • application/pdf — PDF documents
  • application/octet-stream — generic binary (triggers download)

Look Up MIME Types

Use the MIME Type Reference on CodeKitLab to look up MIME types by file extension — searchable and filterable. Setting up server configuration? The Nginx Config Generator and .htaccess Generator help you configure correct MIME types for your server.

Why MIME Types Matter

  • Wrong MIME type = browser won't render the resource correctly
  • Security: browsers enforce strict MIME checking (X-Content-Type-Options: nosniff)
  • API responses need correct Content-Type for clients to parse them
  • File uploads should validate MIME type, not just extension
