Date command<\/p>\n<p> Explanation: Ver command displays the version number of Dos. There is no command as Disk. Format command prepares a disk to be used with DOS. Thus Date is the command that lets you to display and\/or change the system date.<br \/> \u00a0<\/p>\n<p> 3.\u00a0\u00a0\u00a0 While working with Ms-Dos which command transfers a specific file from one disk to another?<br \/> a.\u00a0\u00a0\u00a0 Copy<br \/> b.\u00a0\u00a0\u00a0 Diskcopy<br \/> c.\u00a0\u00a0\u00a0 Time<br \/> d.\u00a0\u00a0\u00a0 Rename<br \/> \u00a0<br \/> Correct Answer: a. Copy<\/p>\n<p> For a specific file to copy from one disk to another disk, Copy command should be used. Diskcopy copies whole disk into new disk. Time command is to display system time and Rename command just changes the name of a file.<br \/> \u00a0<\/p>\n<p> 4.\u00a0\u00a0\u00a0 If you don\u0393\u00c7\u00d6t know the current time, which command will you use to display<br \/> a.\u00a0\u00a0\u00a0 Copy<br \/> b.\u00a0\u00a0\u00a0 Ver<br \/> c.\u00a0\u00a0\u00a0 Time<br \/> d.\u00a0\u00a0\u00a0 Format<br \/> \u00a0<br \/> Correct Answer: c. Time<\/p>\n<p> Explanation: Time command displays and allows you to change system time. TIME only displays the system time and TIME &lt;time&gt; is used to set new time as system time.<br \/> \u00a0<\/p>\n<p> 5.\u00a0\u00a0\u00a0 Which command divides the surface of the blank disk into sectors and assign a unique address to each one<br \/> a.\u00a0\u00a0\u00a0 Ver<br \/> b.\u00a0\u00a0\u00a0 Format<br \/> c.\u00a0\u00a0\u00a0 Fat<br \/> d.\u00a0\u00a0\u00a0 Chkdsk<br \/> \u00a0<\/p>\n<p> Correct Answer: b. Format<\/p>\n<p> Explanation: Ver is used to display the version number of DOS in use. Fat command does not exist and Chkdsk is to check disk errors and fix it. Thus dividing surface into sectors is done by Format command.<br \/> \u00a0<\/p>\n<p> 6.\u00a0\u00a0\u00a0 Each time you turn on your computer, it will check on the control file<\/p>\n<p> a.\u00a0\u00a0\u00a0 Command.com, io.sys<\/p>\n<p> b.\u00a0\u00a0\u00a0 Command.com, date.com, dir.com<\/p>\n<p> c.\u00a0\u00a0\u00a0 Command.com, io.sys, msdos.sys<br \/> d.\u00a0\u00a0\u00a0 Chkdsk.exe<br \/> \u00a0<\/p>\n<p> Correct Answer: c. command.com, io.sys, msdos.sys<\/p>\n<p> Explanation: command.com, io.sys and msdos.sys are the essential system files of MS-Dos. Loading these files from disk into memory is known as booting. Booting is the process of preparing your computer to work.<br \/> \u00a0<\/p>\n<p> 7.\u00a0\u00a0\u00a0 If you need to duplicate the entire disk, which command will you use?<br \/> a.\u00a0\u00a0\u00a0 Copy<br \/> b.\u00a0\u00a0\u00a0 Diskcopy<br \/> c.\u00a0\u00a0\u00a0 Chkdsk<br \/> d.\u00a0\u00a0\u00a0 Format<br \/> \u00a0<\/p>\n<p> Correct Answer: b. Diskcopy<\/p>\n<p> Explanation: Diskcopy is used to perform track-by-track copy of a disk into another. Copy command copies selected files; chkdsk and format commands are not for copying purpose.<br \/> \u00a0<\/p>\n<p> 8.\u00a0\u00a0\u00a0 Which of the following extensions suggest that the file is a backup copy<br \/> a.\u00a0\u00a0\u00a0 Bak<br \/> b.\u00a0\u00a0\u00a0 Bas<br \/> c.\u00a0\u00a0\u00a0 Com<br \/> d.\u00a0\u00a0\u00a0 Txt<br \/> \u00a0<br \/> Correct Answer: a. Bak<\/p>\n<p> Explanation: Bak extension is commonly used to store backup copies of files so that it can be restored later when original file is corrupted or deleted. Bas extension indicates the file is a BASIC program source file, com is command file and txt is plain text file.<br \/> \u00a0<\/p>\n<p> 9.\u00a0\u00a0\u00a0 Which command lists the contents of current directory of a disk<br \/> a.\u00a0\u00a0\u00a0 Copy<br \/> b.\u00a0\u00a0\u00a0 Tree<br \/> c.\u00a0\u00a0\u00a0 Cd<br \/> d.\u00a0\u00a0\u00a0 Dir<br \/> \u00a0<br \/> Correct Answer: Dir<\/p>\n<p> Explanation: Dir command lists the directory of current location. It includes the files, subdirectories and some other system information. Tree command is used to list the directory structure in tree diagram; CD command to change directory and Copy command to copy a file into another.<br \/> \u00a0<\/p>\n<p> 10.Only filenames and extensions are to be displayed in wide format, which command you\u0393\u00c7\u00d6ll use?<br \/> a.\u00a0\u00a0\u00a0 Dir\/w<\/p>\n<p> b.\u00a0\u00a0\u00a0 Dir a:<br \/> c.\u00a0\u00a0\u00a0 Dir\/s<br \/> d.\u00a0\u00a0\u00a0 Dir\/b<br \/> \u00a0<br \/> Correct Answer: Dir\/w<\/p>\n<p> Explanation: Dir\/w only displays the file names and extensions excluding file created date\/time, file size. Second option dir a: will list the contents of A drive (floppy drive), third dir\/s lists current directory and its subdirectories too, dir\/b displays bare format, that means, it just makes a list of files, no more information.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>1.\u00a0\u00a0\u00a0 In MS-Dos 6.22, which part identifies the product uniquely \u00a0 a.\u00a0\u00a0\u00a0 MS b.\u00a0\u00a0\u00a0 DOS c.\u00a0\u00a0\u00a0 Ms-DOS d.\u00a0\u00a0\u00a0 6.22 \u00a0 Correct Answer: d. 6.22 Explanation: MS stands for Microsoft, DOS is the name of operating system Disk Operating System, 6.22 is the version number that identifies the product. \u00a0 2.\u00a0\u00a0\u00a0 In Ms-Dos what command you&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"footnotes":""},"categories":[14],"tags":[],"class_list":["post-150","post","type-post","status-publish","format-standard","hentry","category-operating-systems"],"_links":{"self":[{"href":"https:\/\/temp.ashkerala.com\/index.php?rest_route=\/wp\/v2\/posts\/150","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/temp.ashkerala.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/temp.ashkerala.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/temp.ashkerala.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/temp.ashkerala.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=150"}],"version-history":[{"count":0,"href":"https:\/\/temp.ashkerala.com\/index.php?rest_route=\/wp\/v2\/posts\/150\/revisions"}],"wp:attachment":[{"href":"https:\/\/temp.ashkerala.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=150"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/temp.ashkerala.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=150"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/temp.ashkerala.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=150"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
