Question
Which of the following statements is true? You may select more than one.
A) In Debian Linux version like Lubuntu, sudo apt-get install nameOfThePackage installs the package; sudo apt-get remove nameOfThePackage uninstalls it. The command dpkg -l lists all the packages installed.
B) In Windows, software is packaged in a file format known as .msi, and msiexec.exe installs such packages. When you double-click on a .msi file, the Graphical User Interface (GUI) front-end of this program is invoked by association. The msiexec program has many command-line switches not available through the GUI.
C) In many file system designs, there are two kinds of fragmentations possible. (i) File content is stored in disk blocks. File content is seldom an exact multiple of disk blocks, so the last block used is almost never full. This is known as internal fragmentation. (ii) Large files are almost always stored in non-consecutive blocks scattered around non-volatile memory. This is known as external fragmentation.
D) sudo apt-get update updates the locally stored database of what applications are installed and what newer versions are now available. sudo apt-get update replaces older applications with newer ones.
