Cable length
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.
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.Switches
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.Switch resource
Keyboard switch durability is measured by the number of presses the keys can withstand before they begin to show signs of wear or malfunction. Switches can have a lifespan of several million to tens of millions of clicks. In laboratory conditions, this parameter is checked using special testing machines, which diligently press the keys the required number of times, on the basis of which a verdict is made regarding the approximate service life of the switches.
Polling rate
The frequency with which the computer polls the keyboard to determine which keys are currently being pressed. The parameter is measured in Hertz (Hz) - they show how many requests are executed per second. Higher Hertz means keystrokes are detected and registered faster. This can provide an advantage in games and tasks that require the highest possible input speed.
As for specific values, for most ordinary users the standard polling rate of 125 Hz will be quite sufficient. Gaming keyboards can have a frequency from 1000 Hz (keystrokes in this version are recorded every 1 ms), and advanced models for true e-sportsmen - up to 8000 Hz (the reaction time is 0.125 ms).
#KRO
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.
Metal structure
Keyboards whose body or certain elements are made of metal. This can be either the entire body or its parts - for example, a metal plate as a base for keys. Note that when it comes to the metal construction of the keyboard, the latter option is more common.
Compared to plastic—the most common keyboard case material—metal is much stronger, more durable, and more durable. It has a significant weight, but in this case it can also be written down as advantages — massiveness contributes to stability and reduces the likelihood that the keyboard will "fidget" under the fingers. In addition,
metal cases look stylish and solid. On the other hand, they are noticeably more expensive than plastic ones, and the advantages mentioned are not so much practical as psychological. Therefore, this feature is found mainly in advanced
gaming models (see "By Direction"), for which a solid appearance is no less important than functionality.
