Even if you look at this article from <a href=\"https:\/\/en.wikipedia.org\/wiki\/Computer_data_storage\" target=\"_blank\" rel=\"noopener\">wiki <\/a>\u00a0you&#8217;ll notice that even there the very first line starts with good ambiguity by using the word &#8220;or&#8221;.

In Personal Computers RAM is usually referred as &#8216;memory&#8217;. On the other hand, a hard disk drive is usually the place where data is stored for long or short term retention and thus is known as &#8220;storage&#8221;. They are not obviously not at the same place.<\/p>\n<p>Computer memory needs to be quick. It is constantly feeding the CPU with data to process. Mainframes computers have fast processors and lots of quick memory. There is a thin line between memory and Storage, when it comes to &#8220;paging&#8221; and perhaps this is where these two very different, though similar, concepts creates confusion. In the concept of &#8216;paging&#8217; or &#8220;page swap&#8221; a portion of the DASD (hard disk in computer world) drive is turned into memory for the machine to swap out applications and data from memory to the disk &amp; vice versa. This way, the DASD drive is made into memory, which, while slower than the &#8220;memory&#8221;, can be usefully used to create larger virtual memory spaces for systems.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Both terms are used to refer to internal storage space on a computer and that&#8217;s where the main confusion comes [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[26],"tags":[59,44,37,57,58],"class_list":["post-377","post","type-post","status-publish","format-standard","hentry","category-mainframes","tag-computers","tag-mainframe","tag-mainframes","tag-memory","tag-storage"],"amp_enabled":true,"rttpg_featured_image_url":null,"rttpg_author":{"display_name":"Anuj Dhawan","author_link":"https:\/\/zmainframes.com\/zlog\/author\/anuj-dhawan\/"},"rttpg_comment":4,"rttpg_category":"<a href=\"https:\/\/zmainframes.com\/zlog\/mainframes\/\" rel=\"category tag\">Mainframes<\/a>","rttpg_excerpt":"Both terms are used to refer to internal storage space on a computer and that&#8217;s where the main confusion comes [&hellip;]","_links":{"self":[{"href":"https:\/\/zmainframes.com\/zlog\/wp-json\/wp\/v2\/posts\/377","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zmainframes.com\/zlog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/zmainframes.com\/zlog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/zmainframes.com\/zlog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/zmainframes.com\/zlog\/wp-json\/wp\/v2\/comments?post=377"}],"version-history":[{"count":4,"href":"https:\/\/zmainframes.com\/zlog\/wp-json\/wp\/v2\/posts\/377\/revisions"}],"predecessor-version":[{"id":488,"href":"https:\/\/zmainframes.com\/zlog\/wp-json\/wp\/v2\/posts\/377\/revisions\/488"}],"wp:attachment":[{"href":"https:\/\/zmainframes.com\/zlog\/wp-json\/wp\/v2\/media?parent=377"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/zmainframes.com\/zlog\/wp-json\/wp\/v2\/categories?post=377"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/zmainframes.com\/zlog\/wp-json\/wp\/v2\/tags?post=377"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
