Scan code history

A scan code is a unique binary code which represents a specific key on a keyboard. It is used to identify and communicate the key that has been pressed or released. But where did scan codes come from and how have they evolved over time?

Early keyboard technology

In the early days of keyboard technology, keyboards were connected to computer systems using different interfaces. These interfaces required unique codes to identify the keys on the keyboard. This led to the development of the scan code.

The scan code was first introduced in the late 1970s by IBM for their PC keyboards. It was a way to represent each key on the keyboard with a unique binary code. This allowed the computer system to identify the key that was pressed or released.

Evolution of scan codes

Over the years, scan codes have evolved to support different types of keyboards and layouts. The original scan code set supported the standard 101-key PC keyboard. However, as new keyboards and layouts were introduced, new scan code sets were developed.

Today, different scan code sets are used depending on the type of keyboard and layout. For example, the scan code set used for a laptop keyboard may be different from the scan code set used for a gaming keyboard. This allows the computer system to correctly interpret and process the key presses.

Scan codes are also used in other devices besides keyboards. They are used in barcode scanners, which use scan codes to represent different barcode patterns. This allows the scanner to read and interpret the barcodes.

Conclusion

Scan codes have a long history in keyboard technology. They have evolved to support different types of keyboards and layouts, allowing computer systems to accurately interpret and process key presses. They are also used in other devices, such as barcode scanners. So next time you press a key on your keyboard or scan a barcode, remember the scan code that is being used behind the scenes!

A brief look at the origins and evolution of scan codes

A scan code is a code that is used to represent a specific key on a keyboard, barcode, or other input device. It is a way of encoding the input so that it can be read and understood by a computer or other digital device.

The earliest scan codes were developed in the 1960s as a way to represent the keys on teletype machines. These early codes were simple combinations of numbers and letters that could be easily transmitted and interpreted by the machines. However, they were limited in the number of keys they could represent and were not standardized across different systems.

In the 1980s, the American National Standards Institute (ANSI) introduced the first standardized scan code set, known as the "ANSI scan code set". This set included codes for all of the keys on a standard keyboard and defined how they should be represented in binary format. It also introduced the concept of "extended scan codes" which allowed for a larger number of keys to be represented.

How does a scan code work?

A scan code is typically sent by a keyboard or other input device to a computer or digital device when a key is pressed. The scan code is then interpreted by the device's software or firmware to determine which key was pressed.

The scan code is usually represented as a combination of binary digits that correspond to the specific key on the device. For example, pressing the letter "A" key on a keyboard might send a scan code of "00110001" to the computer.

Once the device receives the scan code, it can be processed and translated into a specific action by the computer or digital device. This could include displaying a character on the screen, executing a command, or performing some other function.

What scan codes are used?

There are several different scan code sets that are used today, depending on the type of device and the specific keyboard layout being used. The most commonly used scan code set is the "IBM PC keyboard scan code set", which is used by most personal computers and compatible devices.

Other scan code sets exist for specialized keyboards, such as those used in gaming or industrial applications. These sets may include additional keys or functions not found on a standard keyboard.

Overall, scan codes have evolved over the years to become a standardized way of representing keyboard and input device keys. They have become an integral part of modern computing and are essential for effective communication between hardware and software.

Scan code future

Scan codes have been used for many years in various industries to track and identify products. But what does the future hold for scan codes?
