Types of Operating Systems
What are the four main categories of operating systems and what is a key characteristic of each?
Business client (used in workplaces for productivity), Network Operating System (supports multi-user environments), Home client (designed for personal use), Cell phone/tablet (optimized for mobile devices).
What are the main features of iOS and Android that make them suitable for mobile devices?
Optimized touch interfaces, app management through vendor-controlled stores, and power/resource optimization for mobile hardware.
What are the primary features of the NTFS file system used in Windows?
Journaling, permissions, encryption, and support for large volumes and files; required for Windows boot volumes.
What are the major differences between Windows Home and Pro editions?
Pro includes domain access, Group Policy, BitLocker, and Remote Desktop server, while Home focuses on entertainment and home use.
What is an in-place upgrade and what are its advantages over a clean installation?
An in-place upgrade installs a new OS version over the current one while preserving apps, settings, and files, minimizing downtime and reconfiguration.
How do Windows and macOS differ in terms of hardware compatibility?
Windows runs on a variety of hardware from multiple vendors, while macOS is only licensed for Apple hardware (Mac, iMac, MacBook).
Why is iOS only compatible with Apple devices?
Apple restricts iOS licensing and installation to its own hardware to ensure tight integration and performance control.
Why might a user choose FAT32 or exFAT over NTFS on a removable device?
FAT32 and exFAT provide better compatibility with non-Windows systems and consumer electronics.
Explain the concept of domain access and why it's important for Pro and Enterprise users.
Domain access allows centralized management of users and devices in a business network, essential for IT administration.
Why is it important to consider hardware compatibility before performing an OS upgrade?
Incompatible hardware can prevent the OS from functioning properly or installing at all, leading to system instability or lack of support.
In what ways is UNIX typically used in modern computing environments?
UNIX is used in servers, workstations, and embedded systems due to its stability and multitasking capabilities.
How do vendor-customized versions of Android affect device compatibility?
They can delay or limit access to updates and features, depending on how the vendor modifies the core Android OS.
How does the ext4 file system improve upon its predecessor ext3 in Linux?
ext4 supports 48-bit addressing, journaling, and better performance, whereas ext3 is limited to 32-bit addressing.
What are the maximum hardware resource limits for Windows Home and Enterprise editions?
Home supports 1 CPU socket, 64 cores, and 128 GB RAM; Enterprise supports 4 sockets, 256 cores, and 6 TB RAM.
How do OEM and retail licenses differ in terms of usage rights and transferability?
OEM licenses are tied to the hardware they’re first installed on and cannot be transferred, while retail licenses can be moved to a different device.
What distinguishes a Linux distribution from the Linux kernel?
The Linux kernel is the core part of the OS, while distributions are complete OS packages that include the kernel and user applications, each tailored for specific use cases.
What is the role of a vendor-managed app store in mobile OS ecosystems?
It provides a secure and curated environment for users to install apps and ensures compliance with platform standards.
What are the key benefits of the Apple File System (APFS)?
Supports 64-bit addressing, encryption, and journaling, optimized for flash/SSD storage on Apple devices.
What are the key stages of a vendor's OS lifecycle, and why are they significant for users?
Beta, supported phase, extended support, and EOL. Each phase affects feature updates, security patches, and support availability.
What are the implications of using volume licensing in an organization?
Volume licensing allows businesses to install and manage the OS across multiple devices efficiently, often with added enterprise features and centralized management.
How does Chrome OS differ from traditional desktop operating systems?
Chrome OS is designed primarily for web applications, emphasizing security and simplicity on Chromebook and Chromebox devices.
Explain how Android’s open-source nature affects its adoption across different manufacturers.
It allows manufacturers to customize and deploy Android on various devices, increasing its market reach and diversity.
What are some typical compatibility issues that arise when upgrading an OS?
Hardware may not meet requirements, peripherals may lack drivers, software may be incompatible, and users may need training.
How do in-place upgrades benefit users transitioning from Windows 10 to Windows 11?
They preserve applications (if compatible), user settings, and data while upgrading the OS directly from the previous version.
How do feature updates differ from quality updates in the Windows OS lifecycle?
Feature updates introduce new capabilities and interface changes, while quality updates address security, stability, and bug fixes without adding new features.
