-rwxr-x-w- 1 user www-data 20 Sep 26 09:58 permissions_example - This file now has
the following permissions:
The user owner, 'user' can: Read, Write and Execute this file (because the permissions
are rwx).
The group owner, 'www-data' can: Read and Execute, but NOT Write (because the
permissions are r-x).
Anyone else can: Write, but not Read or Execute (because the permissions are -w-).
/.::1 - IPV6 loopback address
/.(user)@SANS:~$ - the user account in ()
/.$template statement - for log servers it is the legacy way to declare a template
/.1024 Byte - 1 byte is 8 bits.
1 kibibyte (KiB) is 1024 bytes.
1 mebibyte (MiB) is 1024 kibibytes.
1 gibibyte (GiB) is 1024 mebibytes.
1 tebibyte (TiB) is 1024 gibibytes.
/.127.0.0.1 - IPv4 Loopback Address
/.A Record - is the 'Address Mapping' record. This is the key record that maps a domain
name to an IPv4 address
/.AAAA Record - is the 'IPv6 Address Mapping' record. The equivalent of an A record,
but for IPv6 addresses
/.APFS (Apple File System) - In macOS, the default file system for SSDs; it can also be
used for magnetic hard drives. APFS uses the GUID partitioning system.
*supports permissions and encryption,
*duplicate files can be stored without using additional space, with changes to one copy
of a file being saved as a delta (the difference between the old file and the new file) to
lower space requirements
, /.API (Application Programming Interface) - allows the programmers to write a few lines
of code in their software that will call another application with a query and receive a
response
/.Application Layer - The seventh layer of the OSI model; protocols that enable software
programs to negotiate formatting, procedural, security, synchronization, and other
requirements with the network.
/.apropos - used to search man pages for keywords, usually to find the 'appropriate' tool
to use in a particular situation
/.apt-get - Search for and install software packages (Debian/Ubuntu)
/.ARP (Address Resolution Protocol) - A communications protocol that resolves IP
addresses to MAC addresses.
/.ATX (Advanced Technology Extended) cable - runs to the motherboard
/.Authoritative nameserver - retrieve the specific IP address of the origin server for the
provided web domain name, which the resolver will pass back to the client.
/.bash (Bourne again shell) - Default for most Linux systems, it is an enhanced version
of the original SHELL program.
The default path for bash is /bin/bash. The first '/' means the root of the file system, from
the root of the file system, in the 'bin' folder is the 'bash' program
/.bg (background) - allow process to keep running, except it will run in the background
/.Bios (Basic Input Output Services) - software that helps initialize the hardware in our
computer and gets our operating system up and running
/.Bits - the smallest unit of data in a computer
All data in a computer system is made up of bits:
1 byte is 8 bits.
1 kilobyte (kB) is 1000 bytes.
1 megabyte (MB) is 1000 kilobytes.
1 gigabyte (GB) is 1000 megabytes.
1 terabyte (TB) is 1000 gigabytes.
Oh, and 4 bits (half a byte) is called a nibble...
/.Bootloader - program that is loaded by the BIOS when a computer is first turned on;
responsible for loading the operating system

The group owner, 'www-data' can: Read and Execute, but NOT Write (because the
