Best Answer

Recall that paging is implemented by breaking up an address into a page and offset number. It is most efficient to break the address into X page bits and Y offset bits, rather than perform arithmetic on the address to calculate the page number and offset. Because each bit position represents a power of 2, splitting an address between bits results in a page size that is a power of 2.

Generally, our common PDF documents are all A4 size, but there are always some unconventional sizes. If you want to view the specific paper size, you need to use tools. Since we need to talk about page adjustment operations, use the editor To illustrate. First, after opening the PDF document with Speedpdf Editor, you can view the size of the current document page in the lower right corner of the software page (some PDF documents have different page sizes and different paper sizes). If you need to modify the paper size, that is, the page size, you can use the following two methods: Method 1: Click the page in the document in the upper right corner of the software, and choose to adjust the size. Method 2: After clicking the hand tool in the software menu bar, right-click the mouse anywhere on the document page and select Resize in the document operation. Then go to the next step to set the adjustment page range and new page size and click OK. After the operation is complete, save the PDF document again.
