How are texts entered into the computer

 

Texts are entered into the computer by

Texts are entered into the computer through input devices , which are:

• keyboard.
• Pointing devices.
• the mouse.

Before a computer can process data in general, it needs a method so that it can enter data into the device. The method depends on the type of data to be entered, whether texts, sounds, artwork, etc., as well as some completion of the data entry process into the computer that needs to Processing it and then outputting the results, whether it is also text, audio, or artwork. Therefore, we see that the term “input” and “output” are important terms in the computer, and they are very accurate in describing the process of data entry, output and display in all cases, and the following We will learn about the most important tools through which we can enter data into our computer, especially texts, which are called input devices, which are as follows:

Keyboard: 

The computer keyboard is used to write texts and enter data. It is considered one of the most important main tools in the process of data entry in general, which are indispensable in any computer. It is used to direct commands to the computer to carry out the steps of certain commands. That command, but there are usually several keyboard shortcuts that allow us to carry out commands, in addition to the fact that there are several properties and commands on the keyboard, which is the numeric keypad used to enter numeric data with high efficiency and accuracy, in addition to a set of editing keys, which are called editing keys The text, and there are keys responsible for doing certain functions and those are located at the top of the keyboard and those keys are responsible for the calls and functions of the programs of the computer.

We often find that laptops do not have enough space for a large keyboard, and therefore are short in some things and do not have after keys such as the fn key, but there are double keys that can perform the functions of single keys that are not on the keyboard, such as including The function of the numeric keypad, which is inside the main keyboard keys, but among the important things that must be taken into account is to take into account the use of the keyboard because without it you cannot enter any data, because it can lead to incorrect use or placement of the keyboard, for example The keyboard is designed with certain arrangements and angles for the keys and integrated wrist rests and pads that can reduce the risk of infection with RSIs, and you can also connect External keyboard on any deviceA computer to be able to enter texts whether the keyboard of the device is damaged or not present in the first place as in laptops through a USB connection or via a PS/2 connector.

Pointing devices:

It requires entering texts into the computer and certain destinations for use, such as pointer devices, which are closely related to the mouse, and those destinations require the use of certain graphics such as GUI, which is now used to determine the subject of the pointer on the computer screen, so the visa is the mouse used and the trackball The touchpad, the device’s track point, the graphics panel, the joystick, and of course the screen, all of these things are essential and contribute mainly to the way text is entered into the computer. Ps/2, or through the USP connection, but now it has been updated and the mouse can be connected to the device through Bluetooth, as well as there are computers in which the screen is used to enter data and texts through touch and an internal keyboard.

Mouse:

 The mouse is also one of the basic factors in entering text and data to the computer, because through it the cursor is moved and controlled its actions and given the necessary commands to manage a specific text, whether when entering text into the Excel program or other programs that require the selection of certain commands to enter The text and save what was entered through the menus on the toolbar, the mouse contributes to entering data by moving it, and then the rollers in it sense the movement and transfer the information to the device through the existing wires or through the touch movement in portable computers, and there are types of The mouse is like an optical mouse, through which the light emitted and sensed by the computer is used to give commands and detect the movement of the mouse, and it is often the mouse that is used through remote connection, that is, there is no type of wire. 

The sounds are extracted into the computer through a device

The sounds are extracted into the computer through the headphones device.

The output devices in the computer work on converting the transmitted signals in the form of vibrations, which are the sound, translating them and decoding the codes in order to eventually turn them into an understandable sound, and they are output via headphones or the manual microphone. But in order to be able to do that, he must have assistants, and that external help is the devices connected to him, which are the speakers, whether external, internal or portable, in fact. 

Some devices only have audio outputs, although most existing audio equipment already contains internal equipment that supports the input and output feature, for example, an MP3 player is an output device that emits the signals sent to it through the computer and outputs them In the form of audible sound, the signals emitted from the music file are processed by the player, but since its function is to play music only and not to send sound, there is no need to go to the inputs of the device, another example of the audio output process is our topic speakers Sound or speakers, headphones are one of the main ways in which most people listen to sound, which can be built into a computer such as a laptop computer or laptop as it is called, or external wired to a computer, and are classified into Types in terms of intensity in the extent of sound emission, and have a deviceThe last accessory to it, which is also a means of audio output, is the microphone, which works with two features at the same time, namely, the input feature and the output feature.
