Describe how the Logical Volume Manager (LVM) is used, and then list some of the different components involved.?
What will be an ideal response?
?Volumes created by the Logical Volume Manager can contain a filesystem and can be mounted to directories within the Linux filesystem hierarchy. Using volumes to host filesystems is far more flexible than using standard partitions since it allows you to select free space from unused partitions across multiple hard disks in your computer. This free space is then pooled together into a single group from which volumes can be created. These volumes can then be formatted with a filesystem and mounted to a directory on the Linux filesystem hierarchy. Furthermore, additional hard disks can easily be added to the LVM, where existing volumes can take advantage of the additional storage space. ?The LVM consists of several different components:Physical Volumes (PVs) are unused partitions on hard disks that the LVM can use to store information.Volume Groups (VGs) contain one or more PVs. They represent the pools of hard disk storage space that are available to the LVM for creating logical volumes. Additional PVs can easily be added to a VG after creation.Logical Volumes (LVs) are the usable volumes that are created by the LVM from the available storage space within a VG. LVs contain a filesystem and are mounted to a directory in the Linux filesystem hierarchy. In addition, LVs can be resized easily by the LVM to use more or less storage space.

Answer the following statements true (T) or false (F)
1. The execution of a program consists of the sequential execution of instructions. 2. The “read word from memory” and “increment PC” actions cannot be used simultaneously because they will interfere with each other. 3. Each micro-operation of the fetch cycle involves the movement of data into or out of a register. 4. At the completion of the execute cycle a test is made to determine whether any enabled interrupts have occurred, and if they have, the interrupt cycle occurs. 5. The execute cycle is simple and predictable.
