1. When turning on a computer that has been powered off completely, you are performing a cold boot. A warm boot is the process of using the operating system to restart a computer.
The kernel is memory resident, which means it remains in memory while the computer is running. Other parts of the operating system are nonresident, that is, these instructions remain on a storage medium until they are needed.
2. A user interface controls how you enter data and instructions and how information is displayed on the screen.
With a graphical user interface (GUI), you interact with menus and visual images such as buttons and other graphical objects to issue commands. While to configure devices, manage system resources, and troubleshoot network connections, network administrators and other advanced users work with a command-line interface.
3. With an operating system, you can download and install important operating system and utility updates. updates can include fixes to program bugs, or errors, enhancements to security, modifications to device drivers, access to new or expanded components such as desktop themes or games, and even updates to application software on the computer such as a Web browser or an e-mail program, and the automatic update feature automatically alert users when an update is available; further, it can be configured to download and install the update automatically.
4. During the back up process, the utility monitors progress and alerts you if it needs additional media, such as another disc.
Because they are compressed, you usually cannot use backup files in their backed up form. If you need to use a backup file, a restore utility reverses the process and returns backed up files to their original form. Backup utilities work with a restore utility.
5. Popular embedded operating systems include Windows Embedded CE, Windows Mobile, Palm OS, iPhone OS, BlackBerry, Google Android, embedded Linux, and Symbian OS. Windows Embedded CE is a scaled-down Windows operating system designed for use on communications, entertainment, and computing devices with limited functionality. Windows Mobile, an operating system based on Windows Embedded CE, provides a user interface designed for specifi c types of smart phones and PDAs. Palm OS is an operating system used on smart phones and PDAs. iPhone OS,
The BlackBerry operating system runs on handheld devices supplied by RIM. Google Android is an operating system developed by Google for mobile devices. Embedded Linux is a scaled-down Linux operating system for smart phones, PDAs, portable media players, and other devices requiring an embedded operating system.

1. A higher resolution uses a greater number of pixels and thus provides a smoother, sharper, and clearer image. As you increase the resolution, however, some items on the screen appear smaller.
With LCD monitors and screens, resolution generally is proportional to the size of the device.
2. HDTV is working with digital broadcast signals, transmitting digital sound, supporting wide screens, and providing resolutions up to 1920 3 1080 pixels.
Users plug one end of a cable in the game console and the other end in the video port on the television.
3. Printing using Bluetooth or Infrared.
With Bluetooth printing, a computer or other device transmits output to a printer via radio waves. With infrared printing, a printer communicates with a computer or other device using infrared light waves.
4. Ink-jet printer forms characters and graphics by spraying tiny drops of liquid ink onto a piece of paper.
Professionals require high image quality, such as photography studios, medical labs, and security identification systems, use dye-sublimation printers. These high-end printers cost thousands of dollars and print images in a wide range of sizes. Most dye-sublimation printers for the home or small business user, by contrast, typically print images in only one or two sizes and are much slower than their professional counterparts.
5. Surround sound system may contain speakers ( either satellite one or center one or rear one) and subwoofer.
Audio resolution is is the number of bytes that represent sound in a given time, is stated as a bit rate such as 8-bit, 16-bit, or 24-bit. The three examples of audio resolution is AM radio (8 bit), optical disc-quality sound (16 bit), and high quality digital audio editing (24 bit).

1. Optical mouse, laser mouse, air mouse.
Optical mouse uses devices that emit and sense light to detect the mouse’s movement, while laser mouse uses laser. Air mouse is a motion-sensing mouse that, in addition to the typical buttons, allows you to control objects, media players, and slide shows by moving the mouse in predetermined directions in the air.
2. Point, click, right-click, double-click, triple-click.
Point is the action of moving the mouse until the pointer on the desktop is positioned on the item of choice. Click is pressing and release the primary mouse button, which usually is the left mouse button. Right click is pressing and release the secondary mouse button, which usually is the right mouse button. Double click is the action of quickly pressing and release the left mouse button twice without moving the mouse. Triple click is the action of quickly pressing and release the left mouse button three times without moving the mouse.
3. OCR is a technology that involves reading typewritten, computerprinted, or hand-printed characters from ordinary documents and translating the images into a form that the computer can process.
OMR is a technology that reads hand-drawn marks such as small circles or rectangles.
4. The most widely used biometric device today is a fingerprint reader.
A fingerprint reader, or scanner, captures curves and indentations of a fingerprint. The reader can be set up to perform different functions for different fingers; for example, one finger starts a program and another finger shuts down the computer.
5. The Americans with Disabilities Act (ADA) requires any company with 15 or more employees to make reasonable attempts to accommodate the needs of physically challenged workers.
Computers with gesture recognition capability have the potential to recognize sign language, read lips, track facial movements, or follow eye gazes. For paralyzed or speech impaired individuals, a doctor will
implant a computerized device into the brain.
