Laptop contains all the components of computer but all these are optimized for mobile users.
Personal Digital Assistants(PDAs): A personal digital assistant (PDA) is a handheld computer, also known as small or palmtop computers. Newer PDAs also have both color screens and audio capabilities, enabling them to be used as mobile phones (smartphones), web browsers, or portable media players. Many PDAs can access the Internet, intranets or extranets via Wi-Fi, or Wireless Wide-Area Networks (WWANs). Many PDAs employ touch screen technology.
Workstation: A computer that has a more power resources like Processing Power, Memory and additional capabilities to perform special task refers to as workstation. Workstations are often optimized for displaying and manipulating complex data such as 3D mechanical design, engineering simulation results such as for computational fluid dynamics, animation and rendering of images, and mathematical plots.

Examples of server applications include web servers, e-mail servers, database servers, and file servers.

Supercomputer: A computer which, among existing general-purpose computers at any given time, is superlative, often in several senses: highest computation rate, largest memory, or highest cost. Predominantly, the term refers to the fastest “number crunchers,” that is, machines designed to perform numerical calculations at the highest speed that the latest electronic device technology and the state of the art of computer architecture allow.
Wearable : Wearable computers are computers that are worn on the body. They have been applied to areas such as behavioral modeling, health monitoring systems, information technologies and media development. Government organizations, military, and health professionals have all incorporated wearable computers into their daily operations. Wearable computers are especially useful for applications that require computational support while the user’s hands, voice, eyes or attention are actively engaged with the physical environment.

Workstation:
It isn’t really a computer, this is a terminal with keyboard, mouse, screen and a ethernet+ram devices for connect to the server. Normally these was found at office where the programs are hosted in the server and the terminals connects via pxe protocol.

Really all computers are wereable, i think that u want to define the embedded systems, which has a specific propouses like monitoring health, check your tickets at underground, check the status of your motor engine at cars …
My apologizes for my english but i have to say that, i could say more about computer and differences, but really, u must first say the categories you will define…

Hands down, Apple’s app store wins by a mile. It’s a huge selection of all sorts of apps vs a rather sad selection of a handful for Zune. Microsoft has plans, especially in the realm of games, but I’m not sure I’d want to bet on the future if this aspect is important to you. The iPod is a much better choice in that case.
Skip Hop Studio Diaper Tote Handbag is awesome.So quite a few pockets – and also not really these modest, worthless pockets, either. Almost all of the pockets are a good size and actually support maintain every thing organized. The handles are a great length and fit nicely over the actual shoulder; the handle shoulder straps also remain place on my shoulder, which is actually vital when you’re taking a infant. The bag seems excellent, as well. Not too fancy, but not too casual. (I have it in black) The material is soft (can’t think of a greater word) so it is uncomplicated to squeeze in to tight spaces – but yet it’s sturdy. I’ve a Fleurville Lexi carry and I love it, too, but that tote is actually type of stiff. I believe this Skip*Hop may turn out to be my everyday tote. It is a bit significant – so if you’re not really in to significant hand bags this may well be superior as an over-night diaper handbag.
On a completely anecdotal issue (from my my adversities over 25 years- and not a high quantity of those rather perhaps a fair hundred) i might say that evidence shows correlation.
Compassionate for the practice, but I’m real lovesome the new Zune, and trust this, as asymptomatic as the reviews whatsoever another group human statute, amend you determine if it’s the sect superior for you.
good job man
