Windows 11
Windows 11 is the latest major release of Microsoft's Windows NT operating system, released in October 2021. It is a free upgrade to its predecessor, Windows 10 (2015), and is available for any Windows 10 devices that meet the new Windows 11 system requirements. Windows 11 features major changes to the Windows shell (computing), shell influenced by the canceled Windows 10X, including a redesigned Start menu, the replacement of its "live tiles" with a separate "Widgets" panel on the taskbar, the ability to create tiled sets of windows that can be minimized and restored from the taskbar as a group, and new gaming technologies inherited from Xbox Series X and Series S such as high-dynamic-range video, Auto HDR and DirectStorage on compatible hardware. Internet Explorer (IE) has been replaced by the Chromium (web browser), Chromium-based Microsoft Edge as the default web browser, like its predecessor, Windows 10, and Microsoft Teams is integrated into the Windows shell.

Unicode
Unicode, formally The Unicode Standard,The formal version reference is is an information technology Technical standard, standard for the consistent character encoding, encoding, representation, and handling of Character (computing), text expressed in most of the world's writing systems. The standard, which is maintained by the Unicode Consortium, defines as of the current version (15.0) 149,186 characters covering 161 modern and historic script (Unicode), scripts, as well as symbols, emoji (including in colors), and non-visual control and formatting codes. Unicode's success at unifying character sets has led to its widespread and predominant use in the internationalization and localization of computer software. The standard has been implemented in many recent technologies, including modern operating systems, XML, and most modern programming languages. The Unicode character repertoire is synchronized with Universal Coded Character Set, ISO/IEC 10646, each being code-for-code id ...

2-in-1 PC
A 2-in-1 PC, also known as convertible laptop, 2-in-1 tablet, 2-in-1 laptop, 2-in-1 detachable, laplet, tabtop, laptop tablet, or simply 2-in-1, is a portable computer that has features of both tablets and laptops. Before the emergence of ''2-in-1s'' and their denomination as such, technology journalists used the words ''convertible'' and ''hybrid'' to denominate pre-2-in-1 portable computers: ''Convertible'' typically denominated those that featured a mechanism to conceal the physical keyboard by sliding or rotating it behind the chassis, and ''hybrid'' those that featured a hot-pluggable, complementary, physical keyboard. Both pre-2-in-1 convertibles and hybrids were crossover devices that combined features of both tablets and laptops. The later 2-in-1 PCs comprise a category that is a sibling to both the pre-2-in-1 convertibles and hybrids. Models of 2-in-1 PC were each similarly denominated either a ''2-in-1 convertible'' or ''2-in-1 detachable'', respectively, and despite b ...

Wired Equivalent Privacy
Wired Equivalent Privacy (WEP) was a security algorithm for 802.11 wireless networks. Introduced as part of the original IEEE 802.11 standard ratified in 1997, its intention was to provide data confidentiality comparable to that of a traditional wired network. WEP, recognizable by its key of 10 or 26 hexadecimal digits (40 or 104 bits), was at one time widely used, and was often the first security choice presented to users by router configuration tools. In 2003, the Wi-Fi Alliance announced that WEP had been superseded by Wi-Fi Protected Access (WPA). In 2004, with the ratification of the full 802.11i standard (i.e. WPA2), the IEEE declared that both WEP-40 and WEP-104 have been deprecated. WEP was the only encryption protocol available to 802.11a and 802.11b devices built before the WPA standard, which was available for 802.11g devices. However, some 802.11b devices were later provided with firmware or software updates to enable WPA, and newer devices had it built in. History W ...

Temporal Key Integrity Protocol
Temporal Key Integrity Protocol (TKIP ) is a security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware. This was necessary because the breaking of WEP had left Wi-Fi networks without viable link-layer security, and a solution was required for already deployed hardware. However, TKIP itself is no longer considered secure, and was deprecated in the 2012 revision of the 802.11 standard. Background On October 31, 2002, the Wi-Fi Alliance endorsed TKIP under the name Wi-Fi Protected Access (WPA). The IEEE endorsed the final version of TKIP, along with more robust solutions such as 802.1X and the AES based CCMP, when they published IEEE 802.11i-2004 on 23 July 2004. The Wi-Fi Alliance soon afterwards adopted the full specification under the marketing name WPA2. TKIP was resolved to be deprecated by th ...

Hyper-V
Microsoft Hyper-V, codenamed Viridian, and briefly known before its release as Windows Server Virtualization, is a native hypervisor; it can create virtual machines on x86-64 systems running Windows. Starting with Windows 8, Hyper-V superseded Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V was first released with Windows Server 2008, and has been available without additional charge since Windows Server 2012 and Windows 8. A standalone Windows Hyper-V Server is free, but has a command-line interface only. The last version of free Hyper-V Server is Hyper-V Server 2019, which is based on Windows Server 2019. History A beta version of Hyper-V was shipped with certain x86-64 editions of Windows Server 2008. The finalized version was released on June 26, 2008 and was delivered through Windows Update. Hyper-V has si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AirPods
AirPods are wireless Bluetooth earbuds designed by Apple Inc. They were first announced on September 7, 2016, alongside the iPhone 7. Within two years, they became Apple's most popular accessory. The most recent model, AirPods (3rd generation), are a replacement to the 1st and 2nd generation models, although the 2nd generation is still sold on Apple's website. These models are Apple's entry-level wireless headphones, sold alongside the AirPods Pro and AirPods Max. In addition to playing audio, the AirPods contain a microphone that filters out background noise as well as built-in accelerometers and optical sensors capable of detecting taps and pinches (e.g. double-tap or pinch to pause audio) and placement within the ear, which enables automatic pausing of audio when they are taken out. On March 20, 2019, Apple released the second-generation AirPods, which feature the H1 chip, longer talk time, and hands-free "Hey Siri" support. An optional wireless charging case which costs ...

Wideband Audio
Wideband audio, also known as wideband voice or HD voice, is high definition voice quality for telephony audio, contrasted with standard digital telephony "toll quality". It extends the frequency range of audio signals transmitted over telephone lines, resulting in higher quality speech. The range of the human voice extends from 100 Hz to 17 kHz but traditional, voiceband or narrowband telephone calls limit audio frequencies to the range of 300 Hz to 3.4 kHz. Wideband audio relaxes the bandwidth limitation and transmits in the audio frequency range of 50 Hz to 7 kHz. In addition, some wideband codecs may use a higher audio bit depth of 16 bits to encode samples, also resulting in much better voice quality. Wideband codecs have a typical sample rate of 16 kHz. For superwideband codecs the typical value is 32 kHz. History In 1987, the International Telecommunication Union (ITU) standardized a version of wideband audio known as G.722. Radi ...

Windows 10 Version History
Windows 10 is a series of operating systems developed by Microsoft. Microsoft described Windows 10 as an " operating system as a service" that would receive ongoing updates to its features and functionality, augmented with the ability for enterprise environments to receive non-critical updates at a slower pace or use long-term support milestones that will only receive critical updates, such as security patches, over their five-year lifespan of mainstream support. It was first released in July 2015. Channels Windows 10 Insider Preview builds are delivered to Insiders in three different channels (previously "rings"). Insiders in the Dev Channel (previously ''Fast Ring'') receive updates prior to those in the Beta Channel (previously ''Slow Ring''), but might experience more bugs and other issues. Insiders in the Release Preview Channel (previously ''Release Preview Ring'') do not receive updates until the version is almost available to the public, but are comparatively more s ...

Start Menu
The Start menu is a graphical user interface element used in Microsoft Windows since Windows 95 and in other operating systems. It provides a central launching point for computer programs and performing other tasks in the Windows shell. It is named ''Start screen'' in Windows 8. It has been co-opted by some operating systems (like ReactOS) and Linux Desktop environment, desktop environments for providing a more Windows-like experience, and as such is for example present in KDE, with the name of ''Kickoff Application Launcher,'' and on Xfce with the name of ''Whisker Menu''. Traditionally, the Start menu provided a customizable nested list of programs for the user to launch, as well as a list of most recently opened documents, a way to find files and obtain assistance, and access to the system settings. Later enhancements via Windows Desktop Update included access to special folders such as "My Documents" and "Favorites" (browser bookmarks). Windows XP's Start menu was expanded to ...
