The browser engine, also called the layout or rendering engine, is the part that turns the HTML received from a server into the page you see, and Chrome has used Blink since 2013; Opera and Microsoft Edge use the same engine today, which is why pages look alike in all…

FAT32 records the size of a file in a thirty-two bit field, so the largest single file it can hold is one byte short of four gigabytes; a large film or disk image therefore cannot be copied to a FAT32 drive even when free space is plenty.

Task Manager lists the running applications and background processes with the processor, memory and disk they are using, and it is the tool used to end a program that has stopped responding.

Searching for star dot docx lists every Word document in the folder, and searching for rep star lists every name beginning with those three letters, because the asterisk stands for any sequence of characters including none at all.
