Comparison Qumo Real Steel K05 vs Sven Standard 301

— 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 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.

The number of additional keys provided in the design of the keyboard.

Such keys do not belong to the standard layout and are intended for quick access to specific functions or individual applications — for example, to control the media player or open mail with one click. This function is convenient because commands from additional keys are usually recognized by the system regardless of what is on the screen — thanks to this, for example, you do not have to close the text editor to switch tracks in the player.

Note that in this case we are talking about individual keys that have a strictly defined purpose and corresponding markings. Programmable buttons, the Fn key (see below) and the functions of the main keys implemented through Fn are not taken into account in this paragraph.

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 colour of the backlight provided in the design of the keyboard.

In general, the backlight performs two functions: practical (makes the keys more visible in low light) and aesthetic (gives the keyboard a beautiful appearance). However, it cannot be said that non-backlit keyboards will be unusable in the dark, the light from the monitor will still illuminate the buttons. The simplest version of the backlight is one-colour. In this case, specific colours can be different: for example, white is well suited for general-purpose keyboards (work or home), but other shades can be found in gaming or design models, for example, red, green, blue, purple or orange. If two or three colours are indicated for the keyboard, this may mean either the ability to switch between these colours, or that this model comes in several versions that differ in the shade of the backlight; these nuances should be clarified separately.

The most advanced options are multi-colour and RGB backlighting. Multi-colour systems are called systems in which more than three colour options are provided, sometimes with intermediate shades. And RGB-backlight all...ows you to choose almost any shade at the request of the user; in addition, the possibility of synchronization (see "Illumination with effects") is found mainly in such systems, although single-colour keyboards can also be equipped with other effects.

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").

Keyboards made in a Skeleton case.

The main difference between such cases and the classical ones is that the mechanism of each key is not hidden at the base of the keyboard, but, on the contrary, rises somewhat above it. Due to this, the keys can be easily removed and put back into place, which makes it much easier to clean from dust and dirt. And in gaming keyboards of this type, the kit often includes interchangeable buttons that differ in colour and texture from the main ones. Actually, almost all models with this feature are specifically gaming (see "By Direction").
