low-level software<\/strong> that is permanently stored inside a hardware device.<\/p>\n\n\n\n<p><strong>It gives instructions to the hardware about:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>How to start<\/li>\n\n\n\n<li>How to operate<\/li>\n\n\n\n<li>How to communicate with software<\/li>\n<\/ul>\n\n\n\n<p>You can think of firmware as the \u201cbrain instruction manual\u201d of hardware.<\/p>\n\n\n\n<p><strong>Without firmware:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Your computer cannot start.<\/li>\n\n\n\n<li>Your printer cannot
