Chapter 14 Flashcards
Maintaining and Optimizing OS
Patch Management
Maintaining a system through regular updates (patches)
Windows Update (location?)
Update and Security, in Settings app
Quality Update
Problem fixing patches
Feature Update
New features and full new version of Windows
MacOS Updates (name and location)
Software Update, in Settings
Task Scheduler (snap-in name and function?)
taskschd.msc, can configure executables to run at determined points and conditions
3 parts to Task Scheduler
Triggers (start program), Actions (what program and how it should run), Conditions (criteria to start)
cron
fixed interval program running, on both MacOS and Linux
init system (two types)
launchd (MacOS) and systemd (linux) - another method of running automated exes
Startup Apps
Task Manager OR msconfig.msc
Login Item
MacOS startup apps, in Users and Groups pane of Settings
System Information
msinfo.exe, rundown of hardware, software, and components
Dedicated vs Integrated GPU
Dedicated better at handling heavy loads, integrated more efficient but can struggle
How to roll out updates?
Test updates on individual machines first, phase in updates to catch any bugs testing did not
External Hardware Tokens
USB that holds keys for running apps, must be plugged in to use
4 Considerations for Updating/Installing/Changes
1) Impact on Devices (space, speed)
2) Impact on Network (traffic, security)
3) Impact on Operations (support, deadlines, delays)
4) Impact on Business (Trade-offs, upgrades, efficiencies)
Autorun?
Disable for security, instead manually boot installers
Install an application on Mac?
Drag .app to applications OR run .pkg file
Installing on Linux?
use apt-get command
Performance Options (location?)
System, Advanced System settings
DEP (Data Execution Prevention)
Prevents malware and viruses from taking over applications/processes stored in memory
4 types of Backup
1) Fully backup
2) Incremental backup (with each new change)
3) Differential backup (encompass everything since last full)
4)Synthetic backup (merge your incremental and full)
Final step for backup?
Always VERIFY IT
Standard Backup Rotation Scheme
3-2-1 (3 copies of data, 2 types of media, 1 offsite)
GFS Scheme
Grandfather-Father-Son
Daily-weekly-monthly
Windows OS Backup Tools?
Backup and Restore (Control Panel) - can create backup of entire system, select users and their default directories will be brought along
File History (Control Panel) - need a second drive for this to work, not enabled by default. Specific folders and files
System Restore setup and purpose/timing
In “System Protection” - Create a restore point, typically when a new application is added
