Colour gamut (NTSC)

The colour gamut of the laptop matrix according to the NTSC colour model.

Colour gamut describes the range of colours that can be displayed on the screen. It is indicated as a percentage, but not relative to the entire variety of visible colours, but relative to the conditional colour space (colour model). This is due to the fact that no modern screen is able to display all the colours visible to humans. However, the larger the colour gamut, the wider the screen's capabilities, the better its colour reproduction.

Specifically, NTSC is one of the first colour models created back in 1953 for colour television. It is not used in the production of modern LCD matrices, but is used to describe and compare them. NTSC covers a wider range of colours than sRGB, which is standard in computer technology; therefore, even a small number of percentages in this case corresponds to a fairly wide coverage. For example, a value of 72% or more in NTSC is already considered a good value for use in design and graphics. At the same time, the same NTSC figures on different screens may correspond to different sRGB figures; so if accurate colour reproduction is decisive for you, these details should be clarified before buying.

Also note that among individual monitors, it is easier to find a screen with a wide colour gamut; while it will also cost less than a laptop with similar display characteristics. So choosing a laptop with a h...igh-end screen makes sense mainly when portability is as important to you as high-quality colour reproduction.

Card reader

A device for working with removable memory cards. Usually, it looks like a characteristic slot right on the laptop case, into which the media is inserted. There are different standards for memory cards, a list of compatible standards is indicated in the note to this item. It is worth noting here that for modern laptops it is almost mandatory to support the SD format and its modifications — SD HC, often also SD XC; other options may also be envisaged, but they have not received such distribution. Anyway, this feature is convenient because memory cards are widely used in other types of electronics: for example, SD is the generally accepted standard in digital cameras, and microSD (compatible with SD slots through simple adapters) is used in smartphones. Accordingly, the presence of a card reader greatly facilitates the exchange of data between a laptop and external devices.

USB 2.0

Number of USB 2.0 ports provided in the laptop.

USB of all versions is the most popular modern interface for connecting various peripherals to computer - from keyboards, mice and flash drives to very original devices. It can also be used to charge smartphones and other gadgets. The more USB ports laptop has, the more peripherals you can connect to it without using splitters. Specifically, USB 2.0 is the earliest version found in modern laptops. It uses regular full-size connector and provides speeds of up to 480 Mbit. In light of the emergence of faster and more advanced versions of USB 2.0, it is considered obsolete; more and more laptops are being produced that do not have such connectors at all. At the same time, this interface is still far from completely disappearing, especially since its capabilities are quite sufficient for many peripheral devices.

USB 3.2 gen1

Number of USB 3.2 gen1 ports provided in the laptop. Initially, this interface was called USB 3.0, later USB 3.1 gen1.

Be that as it may, USB is the most popular modern interface for connecting various peripherals to computer - from keyboards, mice and flash drives to very original devices. It can also be used to charge smartphones and other gadgets. And USB 3.2 gen1 is the successor to the popular USB 2.0. In this version, the data transfer speed was increased 10 times - up to 4.8 Gbit/s, and the power supply for external devices was also increased. At the same time, devices with other versions of USB can be connected to the USB 3.2 gen1 port - the main thing is that they have full-size USB A plugs and have enough power for normal operation.

As for the number of USB connectors, the more there are, the more peripherals you can connect to the laptop without using splitters.

USB C 3.2 gen1

The number of USB-C 3.2 gen1 ports provided in the laptop (these connectors were previously labeled USB-C 3.1 gen1 and USB-C 3.0).

USB-C is a relatively new universal connector designed for use in desktop and laptop computers and other devices. It is slightly larger than microUSB, has a convenient double-sided design (it doesn’t matter which side you connect the plug), and also allows you to implement increased power supply and a number of special functions. In addition, the same connector is standardly used in the Thunderbolt interface versions v3 and v4, and technically it can be used for other interfaces; so in some laptops USB-C has a combined purpose — see "Alternate Mode" for more details. And in some models (mostly the most compact ones), USB-C can also charge the device’s own battery.

Specifically, USB-C version 3.2 gen1 allows connection speeds up to 5 Gbps. As for the number of such ports, it is most often small — usually 1 – 2. This is due to the fact that peripherals for USB-C are produced noticeably less than for full-sized USBs. However, in some configurations, the number of connectors of this type can reach 4.

LAN (RJ-45)

Laptop LAN interface version.

LAN (RJ-45, colloquially “twisted pair”) is standard connector for wired connections to computer networks. The version of this connector is identified by the maximum data transfer rate that it supports. In practice, in most cases, 100 Mbit/s is quite enough, however, the development and cheaper technology has led to the fact that more and more laptops are equipped with 1 Gbit/s LAN; such connectors are used even among budget devices. And the most advanced version found in modern laptops is 10 Gbit/s. Mostly gaming models are equipped with such interfaces: high speed, among other things, reduces lag (latency) in online games.

Battery capacity

The capacity of the included laptop battery in milliamp-hours (mAh).

Higher capacity allows the laptop to work longer on a charge, all other things being equal. However, keep in mind that the actual battery life will depend not only on the battery, but also on the power consumption of the laptop itself — and it is determined by both the hardware platform and the installed software. Therefore, only models with similar characteristics can be compared with each other according to this indicator. And if you need a “long-playing” laptop or laptop with very good battery life, you should choose it not by battery capacity, but by directly stated operating time.

Regarding milliamp hours, it is also worth noting that this is not a very reliable (although the most popular) unit of capacity: the actual amount of energy stored in a battery depends not only on milliamp hours, but also on the operating voltage. A more correct unit in this sense is watt-hours, for details on them, see p. "Battery capacity" below. As for specific numbers, the most modest models in this regard are equipped with batteries of 3000 – 4000 mAh and even less. 4000 – 5000 mAh can be called an average, 5000 – 6000 mAh is above average, and the most capacious laptop batteries can hold 6000 -7000 mAh or more.

Battery capacity

The capacity of the complete laptop battery in watt-hours.

Higher capacity allows the laptop to work longer on a charge, all other things being equal. However, keep in mind that the actual battery life will depend not only on the characteristics of the battery, but also on the power consumption of the laptop itself — and it is determined by both hardware characteristics and installed software. Therefore, only models with similar characteristics can be compared with each other according to this indicator. And if you need a “long-playing” laptop, you should choose it not by battery capacity, but by directly stated operating time.

As for watt hours, this is a less popular unit of capacity than milliamp hours, but more physically correct: it accurately describes the amount of energy stored by a battery. Thanks to this, in terms of capacity in Wh, it is possible to compare batteries with different nominal voltages (whereas this is not allowed for mAh — additional calculations must be carried out using special formulas). At the same time, Wh can be easily converted to mAh if the battery voltage is known: for this, the capacity in Wh must be divided by the voltage and multiplied by 1000.

Battery voltage

Rated voltage of the battery supplied with the laptop.

In fact, most users do not need to pay special attention to this parameter. The battery is selected by the manufacturer in such a way as to ensure the battery life and power efficiency planned for this model, so when choosing, it makes sense to look at more "close to life" indicators — first of all, the maximum operating time. Voltage data is needed mainly in specific cases — for example, when looking for a spare battery or transferring capacity from one unit to another (for more details, see "Battery Capacity").
