USB C 3.2 gen2
The number of
USB C 3.2 gen2 ports provided in the laptop (previously, such connectors were labeled USB C 3.1 gen2 and USB C 3.1).
USB C is universal connector created relatively recently and designed for use in desktop and laptop computers. It is slightly larger than microUSB, has convenient double-sided design (no matter which side the plug is connected to), and also allows for increased power supply and number of special functions. In addition, the same connector is standardly used in the Thunderbolt v3 interface, and technically can be used for other interfaces; so in some laptops USB C has combined purpose - see “Alternate Mode” for more details. And in some laptops (mostly the most compact ones), USB C can also charge the device’s own battery.
Specifically, the USB C 3.2 gen2 version allows for connection speeds of up to 10 Gbps. As for the number of such ports, it is most often small - usually 1 - 2. This is due to the fact that significantly fewer peripherals for USB C are produced than for full-size USB. However, in some configurations the number of connectors of this type can reach 4.
USB4
The number of USB4 connectors provided in the laptop.
USB4 is a high-speed revision of the USB interface introduced in 2019. It uses only symmetrical USB-C connectors and does not have its own data format — instead, such a connection is used to transfer information according to several standards at once: USB 3.2 and DisplayPort as mandatory, as well as PCI-E as an option. Another feature is that USB4 is based on Thunderbolt v3 and uses the same USB-C connector, which often makes
USB4 devices and connectors compatible with Thunderbolt v3 (although this is not strictly required), and Thunderbolt v4 support for this interface is built-in . It is also worth noting that this USB revision allows connecting devices in a daisy chain and by default supports Power Delivery technology, which allows you to optimize the process of charging external gadgets (provided that they also implement this technology).
The maximum data transfer rate for such a connector should be at least 10 Gbps, in fact, options for 20 Gbps and even 40 Gbps are often found (depending on the technologies and standards supported by a particular port). At the same time, the USB4 inputs are quite compatible with peripherals for earlier versions of USB — except that devices with a full-size USB A plug require an adapter.
Thunderbolt interface
The number of
Thunderbolt connectors, as well as their version (
Thunderbolt v3,
Thunderbolt v4,
Thunderbolt v5
Thunderbolt is a universal high-speed interface primarily known from Apple laptops, but used by other manufacturers as well. Such a connection actually combines several interfaces — at least PCI-E for peripherals and DisplayPort for outputting video (and audio) to external screens, and others in recent versions. Thanks to this, Thunderbolt can be used both as a peripheral connector and as a video output. Even greater versatility of this interface is provided by the daisy chain function — serial connection of several devices (up to 6) to one port; moreover, it can be both monitors and other peripherals, and in Apple technology, other “apple” computers. Thus, a small number of connectors can be compensated by serial connection.
— Thunderbolt 3. Version introduced in 2015. In this generation, developers abandoned the DisplayPort connector in favor of the more versatile USB-C. Thus, the Thunderbolt v3 connection in laptops is often implemented not as a separate connector, but as a special mode of operation of the regular USB-C port (see "Alternate Mode"). And outputs and devices for USB4 (see above) can be initially made compatible with this interface as well (although this is no...t strictly required). Also optional, but a very common feature is Power Delivery support, which allows you to supply connected devices with power up to 100 watts over the same cable. Data transfer rates can reach up to 40 Gbps, but keep in mind that if the wire length is more than 0.5 m, a special active cable may be required to maintain this speed. However, conventional passive USB-C cables are also suitable for working with Thunderbolt v3 — except that the speed may be noticeably lower than the maximum possible (albeit above 20 Gbps, which runs USB 3.2 gen2).
Thunderbolt v4. The latest (at the end of 2020) version of this interface, presented in the summer of the same year. It also uses a USB-C connector. Formally, the maximum throughput remains the same as its predecessor — 40 Gbps; however, a number of improvements have significantly increased the actual connectivity. Thus, Thunderbolt v4 allows you to broadcast a signal simultaneously to two 4K monitors (at least) and provides a data transfer rate according to the PCI-E standard of at least 32 Gbps (against 16 Gbps in the previous version). In addition, this interface is mutually compatible with USB4 by default, and the daisy chain function is supplemented by the ability to connect hubs with up to 4 Thunderbolt v4 ports. Other features include protection against DMA (direct memory access) attacks.
— Thunderbolt v5. In the fifth edition, Thunderbolt continues to rely on the USB C connector. In the default configuration, it provides bidirectional throughput of up to 80 Gbps, and Bandwidth Boost technology allows for speeds up to 120 Gbps. Thunderbolt v5 supports multiple 8K monitors, three 4K monitors with 144Hz refresh rate, or one external display with the fastest refresh rate of 540Hz. In addition, PCIe Gen 4 support ensures sufficient bandwidth for external graphics cards (up to 64 Gbps), which opens up new possibilities for using AI and machine learning. Through the Thunderbolt v5 interface, charging power of up to 240 W is transmitted using USB Power Delivery 3.1 technology - the most powerful and energy-hungry laptops can be safely charged via the USB port.Power supply Included
The maximum power of the power supply in watts from which the laptop is supplied with power. Note that in this case the maximum power level is indicated, and this is achieved only when performing the most energy-intensive tasks, such as playing games, video rendering, etc. The rest of the time the power supply consumes an order of magnitude less power. This parameter may be useful when calculating the load when connecting a laptop computer to an uninterruptible power supply (UPS) or other means of autonomous power supply. When choosing a power supply yourself, you need to purchase it with parameters similar to the original unit or with a small power reserve on the larger side.
Preinstalled OS
The operating system (OS) installed on the laptop as standard.
The OS is the software base, the environment in which the rest of the “software” of the laptop functions. The capabilities of the device and its compatibility with certain software products largely depend on its brand and version / edition. Theoretically, the pre-installed operating system can be changed to another, but in fact this is not always justified. In particular, the pre-installed OS is usually optimally configured for a specific hardware configuration, while other options may not work correctly.
Among the operating systems relevant for modern laptops, it is worth noting, first of all, the various editions
of Windows 10 — in particular,
Windows 10 Home and
Windows 10 Pro(including versions with the so-called S Mode), as well as
Windows 11, which similarly have
Home and
Pro versions. . An alternative is
Linux(including the Endless OS version); and Apple installs a proprietary solution on its laptops — macOS. Of course, devices are produced
without a pre-installed OS at all (they also include laptops with DOS on board). Here is a more detailed description of these options:
— Windows 10. This OS was release
...d in the fall of 2014 as the next update of the desktop OS family from Microsoft and the successor to Windows 8.1 (number 9 was omitted for technical reasons). It introduced many innovations, such as the built-in Cortana voice assistant, the Edge browser, support for multiple desktops, updated Start menu and notification centre, a major update of standard pre-installed programs, etc. In addition, the system also received an edition of Windows 10 Mobile, which gave a high degree of integration between smartphones and PC / laptops; however, the mobile version was generally unsuccessful and was discontinued in early 2020. Windows 10 is paid, its cost is included in the price of the device. Currently, among laptops it can be found in the following editions:
- Windows 10 Home. "Home" edition — designed mainly for undemanding users who do not need special professional features. Windows 10 Home has all the basic features of the system, but lacks corporate tools, as well as the ability to manage the Update Centre and access the computer via remote desktop.
- Windows 10 Pro. An extended edition of Windows 10 described above, designed for use in the professional field and designed for IT professionals and advanced enthusiasts. In addition to all the features available in the Home edition, it also offers a number of professional and corporate tools — in particular, Active Directory, remote desktop, BitLocker encryptor, and a tool for working with Hyper V virtual machines. however, the more advanced Pro For Workstations edition is designed for high-end workstations, and it simply does not make sense to use it in laptops.
- Windows 10 S Mode. “S-Mode” is a specific version of Windows 10 available for both the Home and Pro editions described above. Such solutions differ from the original OS in limited functionality. So, various programs can only be installed from the Windows Store, the ability to install from third-party sources is not available. This results in restrictions on the use of peripherals: for some external devices, special functions may not be available due to the inability to install a proprietary driver (however, manufacturers of such devices are gradually correcting the situation by writing applications for the Windows Store). Only the standard Microsoft Edge is available as a browser, and Bing is available as a built-in search engine. All this narrows the possibilities for using the system, but significantly increases its security and speed. The latter is especially effective with weak hardware: on such equipment, Windows 10 S Mode is much more comfortable to use than one or another original edition. As for security, it is ensured by careful control of applications published in the Windows Store. The creators position S Mode as the best solution for the educational sector, but in general, this edition is well suited primarily for simple tasks like Internet surfing or working with documents. It is possible to switch from S Mode to the regular version of Windows 10 in the appropriate edition for free — however, this action cannot be undone, and most often it leads to significant performance losses.
— Windows 11. The first major system update from Microsoft in the last six years since the release of "tens". The OS has redrawn most of the icons of standard programs and window controls, the lion's share of actions is accompanied by new animation. The main thing in the redesign is the Start menu button that has moved to a place in the centre of the lower part of the screen. Together with the operating system, Android applications debuted in the Microsoft Store. In general, the system can be considered as a big update of Windows 10 with a serious redesign of the interface, rather than a radically new OS.
As before, Windows 11 is divided into two large camps: Home and Pro. More narrowly targeted versions of this operating system (Education, Enterprise, Mixed Reality, etc.) are also being released.
— macOS. The operating system used exclusively in Apple computers and laptops. Until 2016 it was known as OS X, earlier, until 2012 — as Mac OS. In general, it is considered very reliable and stable, and not without reason: there are relatively few computers for this system, which allows you to well optimize the software part for specific hardware platforms. In terms of application, macOS has proven itself as a solution for professional use: working with documents, design, audio and video editing. At the same time, relatively few games have been created for this OS. The system is updated regularly, and updates are free and available for the life of the laptop. In addition, it is worth noting that macOS is increasingly integrated with Apple's mobile operating system — iOS. So, as of 2020, for owners of "apple" technology, in particular, the following features are available: moving tasks from device to device (for example, you can start writing a letter on a laptop and finish on a smartphone); shared clipboard; duplicating an image from a computer / laptop screen to an iPad; using a portable gadget as an interactive graphics tablet for Mac (including in notes); the possibility of voice and text (SMS) communication from a computer / laptop via a smartphone; transferring photos and scanned materials from a smartphone to a computer / laptop; Mac auto-unlock with Apple Watch, etc.
— Linux. Free and open source operating system. Developed and maintained by a community of programmers around the world. It has its own graphical interface and software tools, which is quite sufficient for solving most everyday tasks, and open source code gives experienced users ample opportunity to customize the system and write their own software. At the same time, there are different Linux distributions — both complex and advanced for enthusiasts, and simple and "friendly", designed for inexperienced users (the representative of the second category, in fact, is the Endless OS described below, but it is often positioned as a separate "OS") . In addition, almost no viruses and other malicious programs are made under Linux. In general, this OS is quite enough for most simple household and work tasks, but games and professional software for it are produced noticeably less than for Windows.
— EndlessOS. A free operating system, which is actually a specific distribution of the Linux described above. It has the same basic features and is fully compatible with Linux applications, and Endless OS has two key differences. Firstly, this OS was created for maximum simplicity, clarity and accessibility even for novice users. Secondly, the standard distribution of Endless OS includes more than 100 additional applications and a lot of reference materials — in case the user does not have the Internet or access to downloading applications is limited in speed or volume. However, there is an edition for those who have no difficulties with communication and who would like to independently choose a set of installed applications.
— DOS. Free operating system with minimal functionality: no graphical interface, controlled via a text command line. In fact, in modern laptops, such a system is intended solely for checking the overall performance; for other purposes, the use of DOS is impossible or does not make sense.
— No OS. The absence of any operating system in the laptop. This configuration does not allow using the device out of the box, but it has an important advantage: the user can choose a specific OS and its edition at his discretion, depending on current tasks and the available low-cost. However buying a paid “OS” separately from a laptop can cost more than purchasing a similar device with a preinstalled OS in the same edition; on the other hand, even with this in mind, such an option is often more preferable and profitable than buying a laptop with an unsuitable pre-installed OS.
The list of rarer and/or obsolete systems includes, in particular, the following:
— Android. Free and open source operating system developed by Google. Initially, it was created for mobile gadgets with the appropriate hardware (energy-efficient system-on-chip processors) and touch screens — primarily smartphones and tablets. Android itself is characterized by tight integration with Google services and an extensive set of applications available through the Google Play market; however, some manufacturers create proprietary software shells based on this OS, including support for their own services and software repositories. Specifically, in laptops, attempts to implement Android have not yet been particularly successful, so this OS can be found mainly in single models of transformers and 2-in-1 devices (see "Type"). This is partly due to the fact that this system is mainly entertainment and multimedia and is relatively poorly suited for work use (although the latter is also possible due to the abundance of applications).
— Windows earlier than Windows 10 (from newest to oldest):
- Windows 8 (in Core, Pro and RT editions);
- Windows 7 (five editions);
- Windows Vista (four editions);
- Windows XP.
All these systems are completely obsolete and are not installed on modern laptops. And for devices running Windows 7 and Windows 8, a free upgrade to Windows 10 is available.
— Chrome OS. Another software product from Google, originally created just for laptops (unlike Android). A key feature of Chrome OS is tight integration with web services: for example, until 2016, the system did not provide the installation of additional programs at all — instead, it was supposed to use web applications opened through the Chrome browser. Actually, Chrome is initially the software basis of the entire OS (hence the name). In the aforementioned 2016, it became possible to install Android applications from the Google Play store on Chrome OS. Specifically, laptops based on this operating system (“Chromebooks”), on the one hand, have shown themselves to be the most inexpensive and affordable devices, convenient, in particular, for use in the educational field. On the other hand, the lack of "native" applications can be a significant inconvenience; and software for Android is usually poorly optimized for ChromeOS — for a number of reasons, developers have little interest in such optimization. And the additional hardware capabilities of Chromebooks as a whole are noticeably more modest than those of their counterparts for Windows and macOS. As a result, such laptops are rare, and the prospects for the system itself are rather vague.
— Meego. Completely obsolete free operating system jointly developed by Nokia and Intel; has not been applied since 2013.
