Personal Computing on a Linux Box
1. For accurate time stamps in logs, for ensuring that processes run on time, and also for applications that depend on keeping good time.
2. “Root” is the user name or account that by default has access to all commands and files on a Linux OS. It is also referred to as the root account, root user and the superuser.
3. It is intended primarily for workstation use--i.e., personal computing on a Linux box.
4. “p” for primary,”e” for extended, and “l” for logical partitions
5.
a. Make it easier to recover a corrupted file system or operating system installation.
b. Smaller file systems are more efficient
c. Separation of the operating system files from user files may result into a better and secure system.
d. Easier backup and recovery
e. You can increase disk space efficiency by formatting disk with various block sizes. It depends upon usage
f. Boot multiple operating systems such as Linux, Windows and FreeBSD from a single hard disk.
6. It serves as 'backup' RAM. One of the most popular ways to configure SWAP is to double your RAM.
7. Ext4 will use the new data structures only on new data, the old structures will remain untouched and it will be possible to read/modify them when needed.
8. Stores essential information, which is required during login. Username, Password, User ID (UID), Group ID (GID), User ID Info, Home directory, Command/shell.
9. fstab is a system configuration file on Linux and other Unix-like operating systems that contains information about major filesystems on the system.
a. Device name: This is the UNIX filename representing the physical device or partition. Typically, this name starts with /dev.
b. Mount point: This is the UNIX filename on the directory structure where the device or partition is to be mounted.
c. File system type: This field represents the filesystem to be used when mounting the device or partition. Typical values for this field are ext2, ext3, reiserfs, vfat, iso9660, and udf. auto can be used if
