Module 1 - Unit 4 - Management Interfaces Flashcards
What is the registry and how does it distinguishes Windows and Linux?
The registry is a database of configuration settings supporting the Windows Os. Linux uses individual text files to store settings.
What term is used to describe terminating a process that is not responding to user input?
This is often called killing the process
Why might you use the Services snap-in to manage background processes rather than Task Manager?
Task Manager allows you to start and stop services but the Services snap-in also allows you to configure service properties
The Task Scheduler allows you to run a process automatically in Windows. what is a widely used Linux Equivalent
cron is widely used to run tasks automatically in Linux
What part of the system memory setup is most user-configurable?
Use of virtual memory or a pagefile, where disk space is used to supplement system RAM
What two things are configured on a disk to make storage space on the disk available to the Windows OS?
The disk must contain at least one partition, typically allocated a drive letter, and the partition must be formatted with a suitable file system
What is a CLI?
A Command Line interface allows the user to interact with the OS using typed command or scripts rather than a GUI
What protection feature in Windows is designed to prevent a script or software from making unauthorized changes to the OS configuration?
User Access Control (UAC). UAC means that the user must input their credentials or click through an authorization prompt before the configuration change can be made
True or false? A standard user cannot change their own password
False–ordinary users can change their own password but cannot change anyone else’s
Management interface
A graphical or command-line tool used to perform some aspect of system configuration
Windows’ management interfaces
Control Panel / Windows Settings
Management Consoles
Windows Computer Management
Contains a number of different administrative snap-ins. Each snap-in configures the settings for a different OS sub-system, such as disk management or user management
Windows Registry Editor
Known as regedit. When you change a setting via a management interface, you are usually changing something stored in the Windows Registry configuration database. The Registry Editor is a means of directly editing this database
How to configure Linux ‘registry’
All configuration is performed by modifying text files
What is a computer process?
A process is the main unit governing a program and managing the memory resources allocated to it by the OS. A process may contain one or more threads, which are parts of the program scheduled for execution by the CPU
What is a Windows’ service?
A service is a Windows process that does not require any sort of user interaction and thus runs in the background. Services provide functionality for many parts of the Windows OS, such as allowing sign in, browsing the network, or indexing file details to optimize searches.
Task Scheduler
Set tasks to run at a particular time. Tasks can be run once at a future date or time or according to a recurring schedule. A task can be a simple application process or a batch file or script
Virtual Memory
Virtual Memory or Pagefile is created by the OS using disk space to supplement RAM by paging it to the disk. This occurs when the OS loads more data than it can fit on the existing system memory modules installed
Disk Management
A tool to format mass storage devices and manage partitions
What are disk partitions?
Partitions allow a single disk to be divided into multiple different logical areas, each of which can be accessed via the OS as a separate drive
Access control
Allow a computing device to have levels of authentication for different users. Some users can have extended authorization for areas of the computer than others, this is known as privileges and restrictions
Least Privilege
A principle that states users should only have sufficient permissions required to perform tasks and no more
User Account Control (UAC)
Windows’ solution to elevated privileges. Earlier versions of Windows allow user to have super privilege, while having the convenience, it also made the system susceptible to malware and viruses. UAC runs in a protected sandbox, where users will be prompted when the application requires administrative access
