Bash is the most likely scripting language to be used in a Linux command-line environment. Bash stands for Bourne-Again Shell, which is a shell program that allows users to interact with the operating system by typing commands or running scripts. Bash is the default shell for most Linux distributions, and it supports features such as variables, loops, functions, and pipes. JavaScript is a scripting language that is mainly used for web development, especially for creating dynamic and interactive web pages. JavaScript can run in a browser or on a server, but it is not commonly used in a Linux command-line environment. PowerShell is a scripting language that is mainly used for Windows administration, especially for automating tasks and managing systems. PowerShell can run commands or scripts in a console or an integrated development environment (IDE), but it is not compatible with Linux by default. C++ is a programming language that is mainly used for software development, especially for creating applications that run close to the hardware or require high performance. C++ can run on various platforms, including Linux, but it is not a scripting language and it requires compilation before execution. References: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 8: Software Development Concepts

Processor speed is measured in hertz (Hz), which is the number of cycles per second that the processor can perform. The higher the processor speed, the faster the processor can execute instructions. Gigahertz (GHz) is equal to one billion hertz, while megahertz (MHz) is equal to one million hertz. Megabits per second (Mbps) and gigabits per second (Gbps) are units of data transfer rate, not processor speed. Therefore, 3.6GHz would indicate the fastest processor speed among the options given. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 3: Computing Components, page 114.

 A byte is a unit of information that consists of eight bits. A bit is a binary digit that can have a value of either 0 or 1. An IP address is 32 bits long, which means it is composed of four groups of eight bits each. Therefore, if converted to bytes, an IP address would be four bytes long. For example, the IP address 192.168.1.1 in binary form is:

11000000.10101000.00000001.00000001

This IP address has four groups of eight bits each, which are equivalent to four bytes. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 6: Infrastructure Concepts, page 221.
