The development of computers and information output devices

Nowadays computers have taken a leading place in human life. From the beginning of development, computers have sought to personalize. Those. Go from the cumbersome computer rooms to miniature PCs. The goal is a computer in every house. However, time changes and science does not stand still. Semiconductors and microcircuits gave a slightly different vision of a home computer. Having achieved the goal - the computer to everyone, the producers asked another - functionality. Now a modern computer is a hybrid of several devices at once, to which you can connect various output devices.

The transition from a quantitative indicator to a qualitative one was due to the achievement of optimal dimensions. Modern touchscreens have made it possible to remove keys and joysticks to enter information. Stationary PCs were aimed more at power characteristics - the amount of operational and permanent memory, the frequency, the number of cores and the size of the video. Nowadays this is conditional, as modern tablet PCs catch up with the parameters of the PC. Now the whole thing is in the screen diagonal and price.

Actually, the tablets owe their appearance not to the PC, but to laptops. Laptops (laptops) became a portable PC with smaller sizes. After them appeared netbooks - a cut-down version of the laptops with a smaller diagonal. A separate contribution was made by mobile phones. They gradually evolved into smartphones and PDAs. The result of the symbiosis of various devices and steel tablet PCs.

In the history of the evolution of computers, peripherals - input devices and output devices - should be noted. The computer itself is a processing center that must have an obligatory interaction with the person. By the means of information input devices, the person (operator) sets the task and the options for its implementation. These include: keyboard, manipulators (mouse, joystick, steering wheel ...), scanner, webcam, touchpad and microphone. Recently, the screen (touch) belongs to them . All of them are divided into different types: sound, video, graphic, text and manipulation.

In turn, the output device is a device that is designed to convert the results of machine code into an understandable (human) form. Variants of types of output can be: visual, tactile, recording, sound and light. Visual output devices - display, printer, projector. Touch tactile joysticks with feedback and specialized printers for the blind. Recorders - drives, flopics (for floppy disks), USB-connectors (for flash drives) and card readers (for memory cards). Sound devices - speakers, headphones, subwoofer and speakers of the system unit. Light - diode indication on other devices and computer parts.

Over time, some output devices just went into oblivion. This is related to the creators of different content. For example, modern games and movies have formats that take up a large amount of space (in GB). Due to the development of graphics in this form of content, disks and disks are a thing of the past. On the other hand, new ones have appeared. The already mentioned display, which became an input-output device of information. Printers have become not only color and printing large formats (plotters), but also reached a new quality level - 3D.

The new fashion - 3D - has made its own adjustments to the entire digital world. In addition to monitors with support for 3D-images, cameras with 3D-shooting, appeared 3D-printers. Now printing on the printer has become more meaningful. This technology is called rapid prototyping. This is quite popular in engineering, medicine and design organizations. Such a printer no longer prints a color image or pseudo-3D, it produces finished items. By the method of sintering a special powder layer by layer you get the output of the part (and even small assemblies). You can talk a lot about the advantages of such an element creation.

The history of the development of computers and their peripherals is quite dynamic. For less than a century, they have surpassed the dynamics of development of any other technology. And what will happen tomorrow, it is already difficult to guess. With respect to the periphery, we can only say that there are still opportunities for unification and hybridization. In any case, it will be interesting to see. In fact, back in the 90s it was considered a powerful PC with a CRT monitor of 14 inches, 128 MB RAM, a 64 MB video card and a 1 GB turbo. And now?..
