Answer Description

The term End of Life (EOL) refers to a product or feature that is no longer supported by the vendor. While it may still function no new updates, security fixes or support will be offered by the vendor. Most software like applications and operating systems have an EOL date.

Wikipedia

An end-of-life product (EOL product) is a product at the end of the product lifecycle which prevents users from receiving updates, indicating that the product is at the end of its useful life (from the vendor's point of view) At this stage, a vendor stops the marketing, selling, or provision of parts, services or software updates for the product (The vendor may simply intend to limit or end support for the product) In the specific case of product sales, a vendor may employ the more specific term "end-of-sale" ("EOS") All users can continue to access discontinued products, but cannot receive security updates and technical support

Answer Description

Android is a mobile operating system that uses a custom Linux kernel. You can imagine a kernel as the brain of an operating system. The type of kernel used in an OS determines what type of OS it is. Linux flavors use a Linux kernel, Windows editions use the Windows NT kernel, iOS and macOS use Apple's XNU kernel (XNU itself is based on Unix). Easy right?

Wikipedia

Android is a mobile operating system based on a modified version of the Linux kernel and other open source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, ability to modify the otherwise FOSS software is usually restricted, either by not providing the corresponding source code or preventing reinstallation through technical measures, rendering the installed version proprietary. Most Android devices ship with additional proprietary software pre-installed, most notably Google Mobile Services (GMS) which includes core apps such as Google Chrome, the digital distribution platform Google Play, and associated Google Play Services development platform. Over 70 percent of Android smartphones run Google's ecosystem; some with vendor-customized user interface and software suite, such as TouchWiz and later One UI by Samsung, and HTC Sense. Competing Android ecosystems and forks include Fire OS (developed by Amazon), HarmonyOS by Huawei or custom ROM such as LineageOS. However, the "Android" name and logo are trademarks of Google which imposes standards to restrict the use of Android branding by "uncertified" devices outside their ecosystem.The source code has been used

An Unattended installation can be used to install Windows 10 without the usual user interface and configuration wizard. This is done by creating a new installer with an answer file which is used to configure the install without prompting the user to answer questions.

Answer Description

Windows 10 comes in several different editions: Home, Pro, Pro for Workstations, S, Education, Pro Education, Enterprise, Enterprise LTSC, X, IoT and Team. The remaining options (with Bing, Starter and Ultimate) have been used in past Windows editions but are not available with Windows 10.

Wikipedia

Windows 10 has several editions, all with varying feature sets, use cases, or intended devices. Certain editions are distributed only on devices directly from an original equipment manufacturer (OEM), while editions such as Enterprise and Education are only available through volume licensing channels. Microsoft also makes editions of Windows 10 available to device manufacturers for use on specific classes of devices, including IoT devices and previously marketed Windows 10 Mobile for smartphones.

Answer Description

BranchCache allows files to be read even when a connection cannot be made with the file server. For example, if a warehouse loses connectivity to the file server in the corporate office hundreds of miles away BranchCache could be used to allow warehouse employees to read locally cached files. BranchCache does not support writing to files unless connectivity to the file server can be established.

Answer Description

Chrome OS is a proprietary operating system made by Google. It is mostly used on laptops known as Chromebooks. Android is not proprietary, the OS and it's source code can be found online for free. Many Android editions exist, some made by Google some made by others like Samsung or online communities.

Wikipedia

Chrome OS (sometimes styled as chromeOS) is a Linux-based operating system designed by Google. It is derived from the free software Chromium OS and uses the Google Chrome web browser as its principal user interface. Unlike Chromium OS, Chrome OS is proprietary software. Google announced the project, then based on Ubuntu, in July 2009, conceiving it as an operating system in which both applications and user data reside in the cloud: hence Chrome OS primarily runs web applications. Source code and a public demo came that November. The first Chrome OS laptop, known as a Chromebook, arrived in May 2011. Initial Chromebook shipments from Samsung and Acer occurred in July 2011. Chrome OS has an integrated media player and file manager. It supports Progressive Web Apps and Chrome Apps; these resemble native applications, as well as remote access to the desktop. As more Chrome OS machines have entered the market, the operating system is now seldom evaluated apart from the hardware that runs it.Android applications started to become available for the operating system in 2014, and in 2016, access to Android apps in Google Play's entirety was introduced on supported Chrome OS devices. Support for a Linux terminal and applications, known as Project Crostini, was released to the stable channel in 2018 with Chrome OS 69. This was made possible via a lightweight Linux kernel that runs containers inside a virtual machine.

Answer Description

Many operating systems come in 32-bit and 64-bit versions. 32-bit versions are becoming less common but can still be found. 32-bit operating systems can only address up to 4GB of memory.

Wikipedia

In computer architecture, 32-bit integers, memory addresses, or other data units are those that are 32 bits (4 octets) wide. Also, 32-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size. 32-bit microcomputers are computers that use 32-bit microprocessors.

Answer Description

A clean installation will completely delete existing data and partitions on the chosen disk. It can be used to re-install the previous OS with a clean state, upgrade an OS or switch operating system types (e.g. from Windows to Linux). If data needs to be kept it should be backed up to a different drive or cloud provider first.

Answer Description

Preboot Execution Environment (PXE) is a special boot type that downloads an image from a server on the network. Fixed Drive is a boot type that uses an internal HDD or SSD. eSata is a type of external drive attachment. FTP is a protocol for transferring files and not a boot type.

Wikipedia

In computing, the Preboot eXecution Environment, PXE (most often pronounced as pixie, often called PXE Boot/pixie boot.) specification describes a standardized client–server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients. On the client side it requires only a PXE-capable network interface controller (NIC), and uses a small set of industry-standard network protocols such as DHCP and TFTP. The concept behind the PXE originated in the early days of protocols like BOOTP/DHCP/TFTP, and as of 2015 it forms part of the Unified Extensible Firmware Interface (UEFI) standard. In modern data centers, PXE is the most frequent choice for operating system booting, installation and deployment.

Answer Description

BitLocker is a full drive encryption solution provided with Microsoft Windows operating systems. TrueCrypt and VeraCrypt are third party encryption solutions and do not come with Windows.

Wikipedia

BitLocker is a full volume encryption feature included with Microsoft Windows versions starting with Windows Vista. It is designed to protect data by providing encryption for entire volumes. By default, it uses the AES encryption algorithm in cipher block chaining (CBC) or XTS mode with a 128-bit or 256-bit key. CBC is not used over the whole disk; it is applied to each individual sector.

Answer Description

An in-place upgrade is an installation type that updates an existing operating system while keeping things like files, applications and settings from the existing operating system.

Answer Description

Certain business focused features like joining an Active Directory domain are not supported in all Windows editions. Windows 7 Home Premium does not include support for joining Active Directory domains.

Answer Description

Windows 8 and 8.1 64-bit support a maximum of 128GB of memory. Other Windows 8 editions go as high as 512GB. This is a limit imposed by Microsoft and not a limit with 64-bit operating systems. In theory a 64-bit operating system can go as high as 16 Exabytes!

Answer Description

Both Bitlocker and Encrypting File System (EFS) are solutions available to Microsoft Windows operating systems. Bitlocker encrypts an entire disk while EFS is a file-level encryption technology.

Wikipedia

The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS that provides filesystem-level encryption. The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer. EFS is available in all versions of Windows except the home versions (see Supported operating systems below) from Windows 2000 onwards. By default, no files are encrypted, but encryption can be enabled by users on a per-file, per-directory, or per-drive basis. Some EFS settings can also be mandated via Group Policy in Windows domain environments.Cryptographic file system implementations for other operating systems are available, but the Microsoft EFS is not compatible with any of them. See also the list of cryptographic file systems.

Answer Description

/Applications is the location of most applications installed on Mac OSX and macOS. C:\Program Files\ and C:\Program Files (x86)\ are similar folders on Windows OS editions. Linux operating systems can greatly vary, but on many you can find many applications at /usr/bin.

Answer Description

Windows 8 has 4 primary editions: Windows 8 (Core), Windows 8 Pro, Windows 8 Enterprise and Windows 8 RT. Windows 8 (Core) is often marketed as simply Windows 8 but many technical docs and other sources refer to it as Core to avoid confusion.

Wikipedia

Windows 8, a major release of the Microsoft Windows operating system, was available in four different editions: Windows 8 (Core), Pro, Enterprise, and RT. Only Windows 8 (Core) and Pro were widely available at retailers. The other editions focus on other markets, such as embedded systems or enterprise. All editions except RT support 32-bit IA-32 CPUs and x64 CPUs.

Answer Description

An application built for one operating system cannot always be run on other operating systems. It will vary from application to application and support for each operating system must be enabled by the developers. Linux and macOS do have many similarities making it common for applications to be supported on both, but it is not automatic or guaranteed.

Answer Description

Google's Chrome OS is unique from other operating systems in that it primarily uses the web browser as it's user interface (Google Chrome). On some devices users can also install Android apps from the Google Play Store. It is not possible to run applications available for other operating systems like Windows and Mac on Chrome OS (unless they have a web version).
