What is keypress?

Types of interrupt?

There are a great many ways in which you could interrupt a person while they talk. You could talk over them.

Does there excist a programme that can rememberwrite-downarchive all the keys you have pushed during the . for instance last five minutes?

Yes. You're looking for a keylogger. You can frequently download free trials of these programs, at sites like http://absolutekeylogger.com/ The program will run in the background and save every keypress as long as it's running.

How do keycodes look?

Keycodes are typically represented as numerical values that correspond to specific keys on a keyboard. For example, the keycode for the "A" key might be represented as 65, while the "Enter" key could be 13. In programming contexts, keycodes can also be displayed in hexadecimal format, such as "0x41" for "A". These codes are used in various applications to detect and respond to keypress events.

What is debouncing?

Debouncing is a provision in electronic/electrical devices having switches to prevent the spikes in output. Details: When we press any switch manually and release it it bounces due to inherent elasticity, this causes multiple make and break of electrical contact. If the response time is very large then it won't create any problem, but if it is small then we get multiple responses for a single keypress.

How do you switch between internal and external monitors on most notebook computers?

Usually it is a special function keypress. Press the Fn key, usually near the ctrl and alt keys at the front left. Then press one of the function keys, usually the one with an extra symbol in the same color as the Fn key that suggests switching monitors. Perhaps two little monitor icons with a / between them.

How many events the text box and button control?

The number of events that a text box and button control can handle typically includes several key interactions. For a text box, common events include "focus," "change," and "keypress." For a button control, typical events include "click," "focus," and "mouse over." The exact number of events may vary depending on the programming environment or framework being used.

How many keystrokes make up one word when typing?

That depends on how the keystrokes are stored. If the ascii or scan code is stored, it's one byte per keypress. Some Chinese input systems using unicode can use up to 4 bytes per keypress.

How do you enter setup con fig mode on Acer computer?

When the Acer screen is displayed during the initial power on, the system should tell you which key to press (different Acers may have a different keypress required to enter the BIOS setup). The most likely options are F1, F2, F10, F12, or Delete. You can also try pressing "Tab" on the Acer screen (on some systems, it will remove the Acer logo and show you the initial boot messages, including which key to press for setup).

What are output devices name them?

The most common output devices are screens (CRT, LCD, LED, plasma and projectors) and printers/plotters. However robotic arms are output devices too. Basically, anything that presents the result of a computation or action is an output device, even if all it does is to turn a diode on and off in response to a keypress. Thus the CAPS LOCK indicator on a keyboard (which is itself an input device) is an output device.

What is polling?

ANSWER I assume you mean polling, where a master device requests the status of a slave device. Another option for a design would be to have the slave device alert the master device when its status has changed. In either case, the master device can then act on the slave's status change. For example, if a computer polls its keyboard, it reads the status at an interval that allows it to detect a keypress. For the other approach, the keyboard has a controller that samples the keyboard (usually much more frequently than the master computer would be polling) and transmits a key code to the main computer.

What are the main causes of interrupts?

Just about any detectable event can be an interrupt for a computer. An event can be something like a keypress on the keyboard, a data stream on a serial input line, when the disk controller detects that the requested data has been read from the disk, when a timer event occurs (some software applications set a timer then "wake up" when the timer expires, that's done with interrupts). Most hardware is associated with some kind of interrupt vector.
