Master Boot Record (MBR)

Device Manager

The apt-get utility

used to control the flow within a computer program or script, usually based on some logic condition. Often, these are implemented with IF THEN ELSE statements.

Global Regular Expression Print

Optical Disk Image (ISO) File

deviates from the initial program path to some sort of logic condition. In this operation, the computer repeats the task until a condition is met. Often implemented with For or While statements. For example, a short script like (For i=1 to 100, print I, next) would print the numbers from 1 to 100 to the screen.

The Swap Partition

used to convert and copy files. On Unix and Unix-like operating systems like Linux, almost everything is treated as a file, even block devices like a hard disk drive. This makes dd useful to clone disks or wipe data from a drive.

popular screen-oriented text editor in Linux, Unix, and other Unix-like operating systems. When using, the terminal screen acts as a window into the editing buffer. Changes made to the editing buffer shall be reflected in the screen display, and the position of the cursor on the screen will indicate the position within the editing buffer.

Comment

a program that scans a device or network for known viruses, Trojans, worms, and other malicious software.

a utility that gathers information about your computer and displays a comprehensive list of hardware, system components, and the software environment that can be used to diagnose computer issues.

32-bit file system supported by Windows, macOS, and Linux computers. The file system can support maximum volume sizes of up to 2 TB and maximum file sizes of up to 4 GB.

determines the route to a destination by sending Internet Control Message Protocol (ICMP) echo packets to the destination. In these packets, tracert uses varying IP Time-To-Live (TTL) values. When the TTL on a packet reaches zero (0), the router sends an IMP "Time Exceeded" message back to the source computer. The ICMP "Time Exceeded" messages that intermediate routers send back show the route.

Simultaneous Authentication of Equals (SAE)

command-line utility that moves files or directories from one place to another. The command supports moving single files, multiple files, and directories. The command can prompt before overwriting files and will only move files that are newer than the destination.

32-bit file system supported by Windows, macOS, and Linux computers. FAT32 can support maximum volume sizes of up to 2 TB and maximum file sizes of up to 4 GB.

lists the files or directories in the current path of a Unix, Linux, or Mac operating system. When invoked without any arguments, this command lists the files in the current working directory.

Fourth Extended File System (ext4)

Constant

File Allocation Table 32-bit (FAT 32)

a Windows file system that supports a 64-bit address space and can provide extra features such as file-by-file compression and RAID support as well as advanced file attribute management tools, encryption, and disk quotas. This file system can support a maximum volume size of up to 8 PB.

Apple File System

displays the present working directory (current directory) path to the terminal or display.

Loop

GUID Partition Table

grep

a device or software application that monitors a system for malicious activity or policy violations. Any malicious activity or violation is typically reported to an administrator or collected centrally using a security information and event management system.

Management Protection Frames

the default file system for Mac computers using macOS 10.13 or later and features strong encryption, space sharing, snapshots, fast directory sizing, and an improved file system fundamentals.

file system optimized for external flash memory storage devices such as USB flash drives and SD cards. exFAT supports a maximum volume size of up to 128 PB with a recommended maximum volume size of 512 TB for the best reliability.

a modern disk partitioning system allowing large numbers of partitions and very large partition sizes. The table is used in modern computers that support the UEFI standard and can support a maximum capacity of up to 9.7 ZB and up to 128 partitions.

displays all current TCP/IP network configuration values on a given system.

placeholder in a script containing a number, character, or string of characters. These scripts do not have to be declared (unlike in programming languages) but can be assigned a value. Then, the name is referenced throughout the script instead of the value itself.

on a Linux system is a portion of the hard disk formatted with a minimal kind of file system and used in situations when the operating system runs out of physical memory and needs more of it. It can only be used by the memory manager and not for the storage of ordinary data files.

Direct× Diagnostic (dxdiag.exe) utility

written into the code to help a human understand the initial programmer's logic. In Python, for example, you can use the # symbol to comment on a line of code. Anything on the line after the # is ignored by the computer when the script is being executed.
