[amp_mcq option1=”DOS=High” option2=”devicehigh=” option3=”loadhigh=” option4=”DOS=UMB E. None of the above” correct=”option2″]<\/p>\n

The correct answer is B. devicehigh=<\/strong>.<\/p>\n

The devicehigh<\/strong> command is used to load device drivers into upper memory blocks (UMBs). UMBs are unused areas of memory above 640 kilobytes (KB) that can be used to load device drivers and TSRs (terminate-and-stay-resident programs).<\/p>\n

To use the devicehigh<\/strong> command, you must first create an UMB. You can do this by using the mem<\/strong> command to see how much unused memory you have above 640 KB. If you have at least 64 KB of unused memory, you can create an UMB by typing the following command:<\/p>\n

memmaker \/c<\/code><\/p>\n

This will create a 64 KB UMB. You can then use the devicehigh<\/strong> command to load device drivers into the UMB. For example, to load the ANSI.SYS<\/strong> driver into the UMB, you would type the following command:<\/p>\n

devicehigh=ansi.sys<\/code><\/p>\n

You can also use the devicehigh<\/strong> command to load multiple device drivers into the same UMB. For example, to load the ANSI.SYS<\/strong> and GRAPHICS.SYS<\/strong> drivers into the same UMB, you would type the following command:<\/p>\n

devicehigh=ansi.sys,graphics.sys<\/code><\/p>\n

The devicehigh<\/strong> command is a powerful tool that can be used to free up conventional memory. By loading device drivers into UMBs, you can free up conventional memory for other programs. This can improve the performance of your computer.<\/p>\n

The other options are not correct.<\/p>\n
