Form factor

Traditional keyboards are divided into three main varieties — full-size, compact and ultra-compact. The main difference between them is that full-size models have a Numpad — an additional block with numeric keys and arithmetic signs. Compact models, respectively, do not have a numpad, and in ultra-compact models, the arrow block is either completely absent or located under the Enter key in the form of very small keys.

And full-size, and compact, and ultra-compact keyboards can have different types of layouts. At the same time, the arrangement of letters and numbers above the letters in all types of layouts is the same, the differences are in the shape and position of additional keys (special characters like backslash, system control, modifiers like Shift and Alt, etc.). Here are the most popular options:

ANSI. The "American" layout format, the distinguishing features of which are, in particular, the same width of both Shift keys, the same labeling and assignment of the Alt keys, the single-row Enter key and the backslash located above it (which is often made slightly longer than the standard key).

ISO. "European" layout format. The Enter key occupies two rows, while at the top it is slightly longer than at the bottom; the left Shift is shorter than the right one, there is a...backslash next to it; next to the bottom of the Enter may be a second backslash or other special character key; the right Alt is designated as Alt Gr and is intended for entering additional characters in European languages.

K.S. The "Korean" keyboard layout provides a double-row Enter, as in the ISO described above, however, in this case, the lower part of the Enter is made longer, and not the upper one. The backslash is above Enter, next to Backspace, and Backspace itself is the same length as standard keys (that is, noticeably shorter than in other layouts).

JIS. Keyboards with a "Japanese" layout have a double-row Enter with an increased length of the upper half — like the ISO described above. However, in this case, the backslash is not located on the left side of the keyboard, but on the right, next to Enter (where an additional symbol key can be located in ISO). Additional character keys may be provided — next to Backspace (as in KS) and/or to the left of the right Shift. In addition, the right Alt can be formatted as Alt Gr.

In addition to compact and full-size, there are also non-traditional keyboard formats:

Numpad. Separately made block of numeric keys. With the help of such a device, you can, in particular, turn a compact keyboard into a full-size one. Among other things, this combination can be useful for travel: packing a Numpad separately from the keyboard is easier than finding a place for a full-sized "board". Another option for using the Numpad is to connect to a cash register, terminal, etc. to work as a calculator keyboard or in a similar capacity.

— Keypad. A specialized device in the form of a small (approximately 15 – 20 keys) keyboard under one hand; usually, it is complemented by an arm rest, and often also by side buttons for the thumb. Such devices are especially convenient for games and are mainly used in them — certain game actions can be attached to the keypad buttons (including those that are usually implemented through the menu or a key combination on a standard keyboard). The keypad can both complement the main keyboard and serve as a completely separate game pad.

— Non-standard. Non-standard format keyboards that do not belong to any of the varieties described above. The specific design and use of such devices may vary. So, these can be game models in the form of the left half of a standard keyboard (this part is mainly used in games); ultra-compact models for tablets (see "In the direction"); keyboards for TVs, supplemented with special buttons and designed to be held in two hands in the manner of a gamepad, etc.

Key profile

The distance that the key travels when pressed — from the initial position to touching the contacts and sending the "command". Indicated as high or low. Keyboards with low key travel(3 mm or less) are considered to be more comfortable for fast input (such as fast typing). However, the best option largely depends on the habits and preferences of a particular user.

Cyrillic colour

The colour of the Cyrillic letters printed on the keyboard.

This colour is usually chosen so that the letters are clearly visible. This point does not affect the functionality of the keyboard, and the choice in this case depends mainly on personal preferences. However, there is also a practical point: for inexperienced users who have not mastered touch typing, it is desirable that the letters stand out as much as possible against the background of the keys.

Transparent letters are a separate case — they are used in keyboards equipped with a backlight (see below), due to which such characters, when the backlight is on, are visible even in the dark.

Volume control

Volume control methodprovided in the keyboard (if such a possibility is provided at all).

Through Fn. Adjustment using the Fn key (see above): increasing and decreasing the volume is carried out by simultaneously pressing Fn and one of the main keys of the keyboard (usually from the F1 — F12 row), The main advantage of this control is that it allows you not to overload the keyboard with additional controls — this, in turn, has a positive effect on the dimensions and cost. The disadvantage is the need to simultaneously press two keys, which is not always convenient.

— Additional keys. Control with additional keys specially designed for working with volume. A very convenient and practical option: additional keys are usually clearly labeled, while they take up less space and are cheaper than a wheel or a touch slider (see below).

— Wheel. Control by means of a mechanical wheel, the rotation of which up and down or left and right provides a change in volume. A fairly user-friendly option — visual, intuitive and accessible even blindly. At the same time, the wheel can take up quite a lot of space, and it significantly affects the cost of the keyboard.

— Touch slider. Management using a touch surface, the movement of a finger in one direction or another. The sensor takes up minimal space, looks neat...and generally fits well with the overall design of the keyboard, but it is not cheap. Therefore, this option is extremely rare, mainly in high-end gaming or multimedia keyboards.

Interface

Interface used in a wired keyboard (see "Connection type").

USB. A standard universal connector for connecting peripherals, present in almost all modern computers — from desktop PCs to microcomputers. USB keyboards are the most versatile, so this option is the most common today. The main disadvantage of this option is that the USB slot occupied by the keyboard may be needed for another peripheral device; however, this problem is quite easily solved — for example, using a USB hub or purchasing a keyboard with its own hub (see below).

PS/2. A specialized connector with a characteristic round shape used to connect keyboards and mice; in modern PCs, both two ports can be provided, for both, and one universal. Anyway, this connection method is convenient in that all USB ports remain free; this can be important when using numerous USB peripherals. At the same time, the PS/2 connector itself is rather large and poorly suited for laptops and other compact equipment, and therefore is found only in desktop PCs. And even in the latter case, it's ok to check the availability of PS/2 before buying a keyboard with such a plug.

— USB or PS/2. Usually, in this case, we mean USB keyboards equipped with an adapter for a PS/2 port. Features of both interfaces are described above; here we note that this option is the most versatile, it allows you to choose the connection method depending on th...e situation. In addition, it is convenient because there are relatively few PS/2 models, and it can be easier to find a suitable USB keyboard equipped with an adapter. The adapters themselves are inexpensive and do not really affect the price of the device; of course, they are sold separately, but the kit is often the preferred option.

— Corporate. Connection using a specific connector, which does not apply to the standard (described above) interfaces and is mainly used in the technique of a certain brand, at best, in some third-party devices. This option can be very convenient for tablet accessories (see "By Direction").

Braided cable

The presence of a braid in the design of a regular keyboard cable.

Braided wire is more durable and reliable than unbraided cable: it is more difficult to damage, it resists sharp bends better. On the other hand, this feature affects the overall cost of the keyboard, and the mentioned advantages do not affect the main functionality of the model. So choosing a keyboard with a braid makes sense only if you are worried about the reliability of the wire, or if you plan to use it in adverse conditions, with frequent squeezing and bending.

Waterproof

Protecting the keyboard from spilling liquid on it. Most waterproof keyboards do not have a full-fledged sealed case and are designed to remain operational in the event of accidental contact with a relatively small amount of liquid (up to 200 mL) — for example, in the classic case of spilling coffee on the keyboard.
