Numbers<\/strong>\n<\/div>\n<div>\n<strong>Count the Dots<\/strong>\n<\/div>\n<p>The binary number system plays a central role in how information of  all kinds is stored on computers.  Understanding binary can lift a lot  of the mystery from computers, because at a fundamental level they're  really just machines for flipping binary digits on and off.   There are  several activities on binary numbers in this document, all simple enough  that they can be used to teach the binary system to anyone who can  count!  Generally children learn the binary system very quickly using  this approach, but we find that many adults are also excited when they  finally understand what bits and bytes really are.<\/p><\/blockquote>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>\u0394\u03b5\u03af\u03c4\u03b5 \u03c4\u03b1 \u03c0\u03b1\u03c1\u03b1\u03ba\u03ac\u03c4\u03c9 \u03b2\u03af\u03bd\u03c4\u03b5\u03bf \u03ba\u03b1\u03b9 \u03bc\u03c0\u03bf\u03c1\u03b5\u03af\u03c4\u03b5 \u03bd\u03b1 \u03ba\u03b1\u03c4\u03b5\u03b2\u03ac\u03c3\u03b5\u03c4\u03b5 \u03ba\u03b1\u03b9 \u03b5\u03ba\u03c0\u03b1\u03b9\u03b4\u03b5\u03c5\u03c4\u03b9\u03ba\u03cc \u03c5\u03bb\u03b9\u03ba\u03cc \u03b3\u03b9\u03b1 \u03bd\u03b1 \u03bf\u03c1\u03b3\u03b1\u03bd\u03ce\u03c3\u03b5\u03c4\u03b5 \u03c4\u03b1 \u03bc\u03b1\u03b8\u03ae\u03bc\u03b1\u03c4\u03ac \u03c3\u03b1\u03c2 \u03b5\u03b4\u03ce (\u0395\u03bb\u03bb\u03b7\u03bd\u03b9\u03ba\u03ac)<\/p>\n","protected":false},"author":1637,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4,32,9,11,33,5,16,19],"tags":[3,8,10,12,17,18],"class_list":["post-754","post","type-post","status-publish","format-standard","hentry","category-4","category-32","category-9","category-11","category-33","category-5","category-16","category-19","tag-3","tag-8","tag-10","tag-12","tag-17","tag-18"],"_links":{"self":[{"href":"https:\/\/blogs.e-me.edu.gr\/ezavag\/wp-json\/wp\/v2\/posts\/754","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blogs.e-me.edu.gr\/ezavag\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blogs.e-me.edu.gr\/ezavag\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.e-me.edu.gr\/ezavag\/wp-json\/wp\/v2\/users\/1637"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.e-me.edu.gr\/ezavag\/wp-json\/wp\/v2\/comments?post=754"}],"version-history":[{"count":0,"href":"https:\/\/blogs.e-me.edu.gr\/ezavag\/wp-json\/wp\/v2\/posts\/754\/revisions"}],"wp:attachment":[{"href":"https:\/\/blogs.e-me.edu.gr\/ezavag\/wp-json\/wp\/v2\/media?parent=754"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blogs.e-me.edu.gr\/ezavag\/wp-json\/wp\/v2\/categories?post=754"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blogs.e-me.edu.gr\/ezavag\/wp-json\/wp\/v2\/tags?post=754"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
