Comparison Logitech G413 vs Xiaomi Mi Keyboard

The length of the cable that the keyboard is equipped with for wired connection (see "Connection type").

When choosing this parameter, you should first of all take into account the distance from the device to the connection port: a cable that is too short may simply not reach the connector, and a cable that is too long may get confused at hand and create inconvenience. As for specific values, the reference length is 1.8 m. However, there are cables both shorter and longer.

— Game. Keyboards designed for use in computer games. Outwardly, they are distinguished by a characteristic design, often quite original and aggressive; some key keys, such as WASD, may be highlighted in colour. In addition, the design may provide various special equipment — additional programmable keys, headphone and microphone jacks, a screen with the ability to display in-game chat, etc. Some of these models are created for specific popular games. Keypads are a separate type of gaming keyboards (see "Format").

— Ergonomic. Ergonomic keyboards are distinguished by a specific layout aimed at making long-term work on them as comfortable as possible. The keys of such keyboards may not be located straight, but in an arc, have a rhombic shape, the alphabetic part of the keyboard itself can be divided into two parts located at an angle to each other, etc. Such design solutions provide a more natural position of the hands during work, which helps to reduce fatigue.

— For tablets. Keyboards specially designed for use with Tablet PCs. They can have special mounts and act as a docking station — with such a keyboard, the tablet practically turns into a netbook, up to the ability to fold the entire structure in the manner of a regular laptop (for ease of transportation and protection of the display from damage). Some models are ini...tially optimized for certain tablets. Because the size of modern tablets rarely exceeds 10", then the keyboards for them are made compact (see "Format").

— Keyboard case. Models that combine the functions of a protective case and a keyboard for entering texts or commands in one bottle. As a rule, keyboard cases are produced for certain tablet models, thereby expanding the functionality of tablet computers. When closed, such accessories tightly fit the tablet body and protect it from damage during transportation. According to the connection methods, keyboard cases can use a Bluetooth connection, proprietary connectors or USB.

— For TV. Keyboards designed for use with Smart TVs. These TVs can connect to the Internet and use various network services, and many of them allow you to install additional applications. Both may require a full keyboard — for example, with its help it is convenient to enter text in Skype, search for content by name, or play some games. Common features of "TV" keyboards are, firstly, a compact format (see below), secondly, wireless connection (in most cases; see "Type of connection"), thirdly, the presence of additional buttons and other controls to operate individual TV functions. When choosing such a model, it is worth clarifying its compatibility with a particular TV.

— Flexible. Keyboards made of elastic materials and having a flexible body — most often in the form of a rubber "mat" with protrusion keys. Such models are extremely easy to transport: a flexible design makes it easy to squeeze the keyboard between other things, bend it, or even roll it up. Another advantage is that the “board” can be easily made moisture resistant (although this is not necessary in this case). At the same time, in terms of the “response” of the keys, a flexible keyboard can differ markedly from more traditional ones, and it may take some getting used to working on it. And in terms of format (see below), such models are most often compact.

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 Num-block — an additional block with numeric keys and arithmetic signs. Compact models, respectively, do not have a num-block, 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, ther...e 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:

— Num-block. 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 Num-block separately from the keyboard is easier than finding a place for a full-sized "board". Another option for using the Num-block 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.

The model of switches (switches) used in the keyboard - switching mechanisms installed under each individual key. These details are given if the design uses advanced mechanics, positioned as a better option than traditional switches. Mostly gaming keyboards are equipped with such mechanics.

The most popular switch brands in our time are Cherry MX, considered the "classic of the genre" for high-quality mechanics; Gateron, practically not inferior to him; not so advanced, but also cheaper Kailh and Razer, as well as ultra-budget Outemu. For all these brands, different types of switches have a different stem color, which can be used to determine the features of the keyboard. It is also worth saying that modern mechanical switches are divided into three main varieties: linear, tactile and clicky.

- Linear. Such solutions are closest to conventional membrane keyboards: the key travel is uniform along the entire length, with minimal resistance and the absence of a clear actuation point. There is an opinion that the linear "mechanics" is best suited for games where you have to deal with fast and frequent clicks; however, in practice, this moment largely depends on the personal tastes of the u...ser, nothing prevents the use of such keyboards for working with texts.

- Tactile. Switches with a clearly defined actuation point - a kind of barrier to the path of the key. Such a "barrier" allows you to clearly determine by touch whether the key has worked or not. Tactile keyboards are valued primarily by tech who have to type large volumes of texts.

- Tactile-auditory (Clicky). In such switches, the actuation point is felt not only by touch, but also by ear: the actuation of the key is accompanied by a clearly audible click, which is often compared to the sound of the keys of a typewriter. Due to this, this option is also very popular among users dealing with texts. Some people consider switches of this type not very suitable for games, since they are supposedly not very convenient for frequent, fast pressing; however, a quality Clicky switch is as good as a linear switch in this regard, and the choice depends solely on personal preference. But the unequivocal disadvantages of such keyboards include a rather loud click sound, which in some situations may be superfluous.

As for specific colors, here are their features:

- Red (red). Linear type switches with minimum resistance. They are popular, in particular, among professional gamers who deal with dynamic games and try by all means to speed up their reaction to gaming events. On the other hand, a low force increases the likelihood of accidentally pressing an unnecessary button.

— Black. Another type of linear switches. They have a tighter move compared to Red, which, on the one hand, requires a little more effort, on the other hand, minimizes the chance of accidentally pressing the wrong key.

Blue. Switches in clicky format, with tactile feedback and a click.

— Brown. Switches with tactile feedback, but no "click". The Brown action is great for when you want a keyboard with tactile feedback and at the same time you want to avoid unnecessary noise (although the sound is still louder than on a membrane keyboard). In addition, it is considered a good option for tech who are just starting to get acquainted with mechanical keyboards.

— Silver. Linear switches designed for maximum operating speed. They have a very low stroke - about 1 - 1.2 mm - as well as a very small pressing force, which contributes to high speed. At the same time, the use of such a keyboard requires a certain skill, since even a small effort from an accidental touch usually leads to the operation of a key.

Technology aimed at neutralizing phantom button presses in keyboards with gaming ambitions. The function allows you to simultaneously press numerous keys without false positives of adjacent buttons — a similar situation often occurs in membrane keyboards due to their design features.

A parameter that determines the maximum number of simultaneously pressed keys, the signal from which the keyboard is able to process and transmit to the computer. Instead of the "lattice" symbol in the abbreviation KRO, a number is indicated showing the allowable number of simultaneously pressed buttons. Most membrane keyboards come in the 2KRO and 3KRO grades, mechanical models usually start at 6KRO. The NKRO marking says that it is possible to issue a signal from an unlimited number of keys in one sitting.

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.

The presence in the keyboard of a special game mode.

This function is found exclusively in models of the corresponding specialization (see "Intended use"). Enabling Game Mode disables some of the keys and keyboard shortcuts used by the system, such as the Windows Start menu button and the context menu button. Thanks to this, you do not have to worry that an accidental key press will call a system function and interrupt the game.

In many models, you can customize a specific set of keys that are deactivated in the game mode.

The number of native USB ports in the keyboard design.

The presence of these ports actually allows you to use the keyboard as a USB hub — for connecting various peripherals to a computer. Such a connection is convenient because the connectors are literally at hand, you do not need to reach for the system unit. The number of ports corresponds to the number of USB devices that can be connected to the keyboard at the same time without the use of splitters and other additional equipment.
