The material explains mainframe hardware and peripheral devices, then expands into a learning pathway for students and beginners. Early chapters outline what a mainframe is, who uses it, typical workloads, and how z/OS relates to other operating systems. It also begins the curriculum for interactive facilities and key system capabilities, supporting review questions and discussion topics.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":30,"@type":76,"position":81},"https://docshare.wps.com/document/technology/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/introduction-to-the-new-mainframe-zos-basics-part-1-introduction-to-zos-and-the-mainframe-environment/292439/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/introduction-to-the-new-mainframe-zos-basics-part-1-introduction-to-zos-and-the-mainframe-environment/292439.png","ImageObject",300,407,{"name":92,"@type":93},"Clementine","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-07","2026-09-17",true,{"@type":102,"interactionType":103,"userInteractionCount":29},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What topics are covered in the new mainframe and z/OS basics introduction?","Question",{"text":112,"@type":113},"The material covers mainframe concepts, z/OS fundamentals, mainframe hardware and peripheral devices, and core operating system and facility overviews.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How is the content organized for learners?",{"text":117,"@type":113},"It is organized by parts and chapters, with each chapter including structured sections plus review questions and topics for further discussion.",{"name":119,"@type":110,"acceptedAnswer":120},"What does the z/OS overview section include?",{"text":121,"@type":113},"It covers what an operating system is, what z/OS is, z/OS facilities, workload management, data and I/O management, supervisory execution, and system and product messages.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},292439,1790828783,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":29,"category_name":30,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":29,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":139,"language":140,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":141,"faqs":142,"seo_title":143,"seo_description":67,"update_tm":144,"read_time":145},1374391974564,"https://ap-avatar.wpscdn.com/avatar/14000253aa45c000a9e?x-image-process=image/resize,m_fixed,w_180,h_180&k=1779874745381141002","Introduction to the New Mainframe z/OS Basics  \nBasic mainframe concepts, including  \nusage and architecture  \nz/OS fundamentals for students  \nand beginners  \n Mainframe hardware and  \nperipheral devices  \nMike Ebbers John Kettner Wayne O’Brien Bill Ogden  \n[ibm.com](ibm.com/redbooks)[/redbooks](ibm.com/redbooks)  \nInternational Technical Support Organization  \nIntroduction to the New Mainframe: z/OS Basics  \nMarch 2011  \nNote: Before using this information and the product it supports, read the information in“Notices” on page xi.  \nThird Edition (March 2011)  \n© Copyright International Business Machines Corporation 2006, 2009, 2011.
