Intro To Operating Systems Final

The correct answers have been provided based on the definitions given for each term. The incorrect answers have been purposely chosen to reflect common misconceptions or misunderstandings of the terms.

The correct answer explains the roles and relationships between programs, processes, and threads in computing. It distinguishes them based on their functions and characteristics.

The Poisson curve is commonly used to approximate the distribution of CPU cycles from both I/O-bound and CPU-bound jobs in a computing system.

Job status can be categorized into different states such as Hold, Ready, Running, Waiting, and Finished based on the current state of the job being processed.

The correct answer provides a comprehensive explanation of each job status state, including Hold, Ready, Running, Waiting, and Finished. The incorrect answers provided are common misconceptions that do not accurately define the job status states.

In order to create an effective job status chart, different shapes and colors should be used to clearly differentiate between the various job statuses. This helps viewers easily understand the information being presented.

In the context of a job's lifecycle, the FINISHED state typically refers to the job either successfully completing its tasks or being forcibly terminated before completion.

Deadlock and starvation are common issues in computing systems that can impact their performance and functionality. It is important to understand the differences between the two to effectively manage and troubleshoot these issues.

The correct option is set /p, which is used to ask the user for information. The other options provided do not perform the same function as set /p in Command Prompt.

The device manager is a system tool in Windows that allows users to view and control the hardware attached to the computer. It is used to manage and control the peripherals such as printers, monitors, keyboards, mice, etc.

RAID stands for Redundant Array of Independent Disks and is primarily used to improve speed and provide backup in data storage systems.

RAID levels 0, 1, 5, and 0+1 each have unique characteristics in terms of data striping, mirroring, and parity for fault tolerance and performance optimization in storage systems.

A file system refers to the way an operating system organizes and manages data on storage devices. It is not limited to physical files in a filing cabinet or the act of creating files. It is not related to internet browsers.

The correct answer highlights the differences in file storage capacity and permissions between FAT16/32 and NTFS. The incorrect answers provide alternative statements that may confuse individuals unfamiliar with the topic.

Linux shell commands provide a way for users to interact with the file system of a Linux operating system by navigating directories, creating files, deleting files, etc. The basic directory structure in Linux is hierarchical and can be manipulated using various shell commands like cd, ls, mkdir, rm, etc.

To change file/directory permissions using chmod, you need to use the chmod command followed by the permission code (such as 755, 644, etc.) and the name of the file or directory you want to modify. The chmod command is specifically designed for changing permissions and is different from other commands like grep, mv, or ls.

Writing a shell script involves using a text editor to manually input commands and save them in a file with a .sh extension. Other software tools like spreadsheet software, web browsers, or photo editing software are not typically used for writing shell scripts.

To convert binary numbers to base 10, each binary digit is multiplied by 2 to the power of its position (starting from 0) and then adding the products together to get the decimal representation.
