Answers
Answer:
1.)Laptops combine all the input/output components and capabilities of a desktop computer, including the display screen, speakers, a keyboard, data storage device, sometimes an optical disc drive, pointing devices (such as a touchpad or trackpad), with an operating system, a processor and memory into a single units.
2.)The desktop is the primary user interface of a computer. ... It includes the desktop background (or wallpaper) and icons of files and folders you may have saved to the desktop. In Windows, the desktop includes a task bar, which is located at the bottom of the screen by default.
3.)A wearable computer is any small technological device capable of storing and processing data that can be worn on the body. Wearable computers are designed for accessibility and convenience, as well as improvements to workplaces by making information quickly and readily available to the wearer.
4.)A small computer that literally fits in your palm. Compared to full-size computers, palmtops are severely limited, but they are practical for certain functions such as phone books and calendars. Palmtops that use a pen rather than a keyboard for input are often called hand-held computers or PDAs.
5.)A netbook belongs to a class of small, lightweight, legacy-free, and inexpensive laptop computers introduced in 2007. Netbooks compete in the same market segment as mobiles and Chromebooks (a variation on the portable network computer)

1.A laptop computer, sometimes called a notebook computer by manufacturers, is a battery- or AC-powered personal computer generally smaller than a briefcase that can easily be transported and conveniently used in temporary spaces such as on airplanes, in libraries, temporary offices, and at meetings.
Laptop computers generally cost more than desktop computers with the same capabilities because they are more difficult to design and manufacture. A laptop can effectively be turned into a desktop computer with a docking station, a hardware frame that supplies connections for peripheral input/output devices such as a printer or larger monitor.
2.A desktop computer is a computer that fits on or under a desk. It has a monitor or another display, keyboard, mouse, and either a horizontal or vertical (tower) form factor. Unlike a laptop, which is portable, a desktop computer usually stays .
Below is a picture of a computer with each of the main components that help make up a computer. In the picture, you can see the desktop computer, flat-panel display, speakers, keyboard, and mouse. We've also labeled each of the input devices and output devices.
3.A wearable computer, also known as a wearable or body-borne computer,[1][2] is a computing device worn on the body[3]
The definition of 'wearable computer' may be narrow or broad, extending to smartphones or even ordinary wristwatches.[4][5]
Wearables may be for general use, in which case they are just a particularly small example of mobile computing. Alternatively they may be for specialized purposes such as fitness trackers. They may incorporate special sensors such as accelerometers, thermometer and heart rate monitors, or novel user interfaces such as Google Glass, an optical head-mounted display controlled by gestures.
4.A small computer that literally fits in your palm. Compared to full-size computers, palmtops are severely limited, but they are practical for certain functions such as phone books and calendars. Palmtops that use a pen rather than a keyboard for input are often called hand-held computers or PDAs.
Because of their small size, most palmtop computers do not include disk drives. However, many contain PCMCIA slots in which you can insert disk drives, modems, memory, and other devices.
5.A Netbook is a new type of laptop computer, defined by size, price, horsepower, and operating system. They are small, cheap, under-powered, and run either an old or unfamiliar operating system.
Netbooks run either Windows XP Home edition or Linux (not only is Linux unfamiliar to many, but the versions of Linux on Netbooks are not the mainstream popular distributions). They do not run XP Professional, Vista, or OS X. Microsoft arbitrarily restricts Netbooks from running the Professional Edition of Windows XP.
