fiasKO [112]2 years ago
6 0

The root account on a Linux or Unix Operating System is the account with the most advanced privileges. The password to this account is called the "Root Password"

<h3>What is a bootloader?</h3>

The first thing that happens when the computer is powered on is that very important software is triggered. It is this software that helps the operating system (OS) to boot or load. This piece of software is called the bootloader.

By default, Unix OS does not have a root password. This must be set by the user. However, if this has been set and was lost, it may be reset using the following steps:

  • Boot to Recovery Mode
  • Drop out to Root Sheet
  • Remount the File System with Write Permissions
  1. here, type exactly the following command: mount -o rw,remount /
  2. Press "Enter" At this point, you should be able to make changes to the data on the hard drive.
  3. Next, enter passwd username
  4. retype the password and user name to confirm, then
  5. type shutdown -r to restart the system.

Normal or random variations that are considered part of operating the system at its current capability are ______: ​ a. systemic
Effectus [21]

Normal or random variations that are considered part of operating the system at its current capability are <u> c. common cause variations.</u>

Explanation:

Common cause variation is fluctuation caused by unknown factors resulting in a steady but random distribution of output around the average of the data.

Common-cause variation is the natural or expected variation in a process.

Common-cause variation is characterised by:

  1. Phenomena constantly active within the system
  2. Variation predictable probabilistically
  3. Irregular variation within a historical experience base

It is a measure of the process potential, or how well the process can perform when special cause variation removed.

Common cause variation arises from external sources that are not inherent in the process and is where statistical quality control methods are most useful.

Statistical process control charts are used when trying to monitor and control 5- and 6-sigma quality levels.
