What's the difference between the terms 'netbook', 'notebook', and 'laptop'? I've always just called portable computers "laptops", but apparently there is a technical difference between the three.

Laptop / Notebook

The term's laptop and notebook are generally interchangable. Traditionally they refer to any type of portable computer. However, with the introduction of the netbook, a laptop generally refers to computers with screens of 14+ inches. These computers are considered "full featured."

Full featured means they have regular Intel or AMD processors and optical drives.

Netbook

A netbook is a small, ultra-portable computer. Microsoft defines a netbook as any portable computer with a screen less than 10.7". They generally weigh less than 3 pounds and have no optical drive. Currently netbooks mostly use the Intel Atom processor.

Ultra-portables

There is another type of laptop that covers portable computers with screens that are 11"-13" in size. These are generally very portable, light-weight, but are full featured (have full blown Intel/AMD processors). They usually have optical drives.

As further reading, here's a recent article arguing it's "Time to drop the Netbook label": edition.cnn.com/2009/TECH/ptech/08/20/cnet.drop.netbook.label/… –  Jonik Aug 22 '09 at 23:15
    
Personally, I don't think we need to drop the term, but make it more relevant - I see them as not just no CD but also solid state (sorry 10" models). –  salmonmoose Aug 27 '09 at 10:03
    
Ultra Portables can have 3-4" screens, like the N800/N810/N900 –  LiraNuna Aug 28 '09 at 8:02

As far as I know, the types of mobile computers are all marketing driven. There are no standards bodies which define the categories (other than, say which computer type Microsoft is willing to license their OS). So there is a lot of crossover in between the categories. And categories come and go based on what sells at the time. Some common categories of mobile computers are:

  1. Desktop Replacement
  2. Laptop
  3. Notebook
  4. Thin & Light Notebook
  5. Ultra-Thin Notebook
  6. Sub-notebook
  7. Netbook

Descriptions of these categories:

  1. Desktop Replacements were popular a few years ago. They typically had poor battery life and were relatively very big and cheap.
  2. Laptops are the most common type (maybe until recently) and typically have most of the features of a desktop computer, but with a 15-17" screen and 1-2 hrs. of battery life.
  3. Notebok computers leave out features commonly found on a desktop computer that aren't needed, have increased battery life and smaller screens (~13" is common).
  4. Thin & Light Notebooks typically have even less features than Notebooks, ~12" screen and have increased battery life with weight in the 4 lbs. range.
  5. Ultra-thin Notebooks, are typically very expensive and have a small profile at the expense of features.
  6. Sub-notebooks (probably the precursor to the Netbook) are notebooks with a reduced feature set that are powerful enough to run a normal OS, but with a tiny tiny keyboard and little 10.1" screen.
  7. Netbooks typically are extremely inexpensive, underpowered computers that are targeted to be good enough for web surfing and email type tasks.

Description #1 -- Desktop Replacements were not cheap -- if anything, they were more than an equivalent desktop due to the need for a monitor and getting everything assembled in a mobile environment. –  Andrew Scagnelli Jul 22 '09 at 17:36
    
By today's standards, you are right, they weren't cheap. But 5-6 years ago, they were the cheapest laptops you could get. They were a hundred or two dollars more than a desktop. The ones I'm thinking of had low end processors (Intel Celeron or AMD Duron), terrible battery life, 17" displays, probably weighed 10-12 lbs. I'm sure there were high end versions of these as well, but my memory is the low end is what was popular. DTR's probably put pressure on the traditional laptop to come down in price. –  hanleyp Jul 23 '09 at 4:56
    
Your are missing a category, portable workstations. There are high end laptops with decent (not spectatural) graphics, processors, memory and drives. They are used as replacements for workstations in areas like CAD. They also make decent game machines. Look at the Dell Precision series as an example. –  Jim C Jan 5 '10 at 13:47

You have to go way back in history to find the original difference between a notebook and laptop. The original laptops were 2-3" thick and weighed 10ish pounds despite having a small LCD. They replaced luggable systems that weighed 20ish pounds, had a suitcase like form factor, typically a mini-CRT as the display, and which had to be thumped onto a desk to be used. The term notebook originally referred to the first systems with a form factor similar to current 14/15" models. Now days the laptop/notebook terms are used synonymously.

Notebook and laptop seem to be very similar in definition. I have never noticed any difference between their uses.

However, netbook is usually used to describe a very small, ultra-portable laptop / notebook. The size is usually smaller than 10" (although some people also use it for 12"), and the weight is usually in the range of 1 - 2 kg.

Laptop means notebook. But there might be some variance in what kind of people use either term, as this Urban Dictionary definition reveals: urbandictionary.com/define.php?term=notebook :) –  Jonik Aug 22 '09 at 23:11

Notebooks and laptops are the same to my knowledge (unless of course you're talking about paper notebooks).

A netbook is a laptop designed primarily for things like internet browsing, word processing, messaging and the like. A netbook is also small enough that you can bring it with you wherever you go. As indicated by the other answers, a netbook is usually no more than 11 inches in size and will not weigh more than 2 or 3 pounds. TYhey also usually (but not always) sport an Intel Atom processor, which is a low powered processor that has the advantage of offering a minimum of power drain.

Microsoft sells XP to netbook manufacturers at a reduced price, so that they don't concede this fastest growing market segment entirely to Linux. To get this reduced price, there is a maximum hardware specification of what Microsoft considers a netbook. It includes a screen no bigger than 10 inches, hard drive of 160 GB, 1 memory slot shipped with at most 1 GB of memory. Many buyers have to throw away the 1 GB SODIMM when they want to upgrade to 2 GB. I don't have a printable reference for this information, I heard it on the [PC Radio Show].[1]

I believe hardware vendors (Intel and AMD, particularly Intel) also have limitations on which chipsets they'll sell to support various levels of CPU. –  mpez0 Apr 14 '10 at 13:20

New terms are invented each time a new class of small computers becomes popular and/or somewhat standardized, to distinguish them from the previous ubiquitous type.

  • "Portable computer" was the original term in the 1970s and 1980s covering machines like the Oborne One, these were retro-named "luggable" later on to make fun of their unwieldy size.
  • "Laptop" took off in the late 1980s to distinguish the first flat, fold-open computers that didn't require a desk.
  • "Notebook" took off in the 1990s to emphasize machines smaller and lighter than the laptops more common up to that time.
  • "Netbook" took off a few years ago to describe very small laptops with wi-fi internet but without legacy features like disk drives.

Of these terms, all have levelled off in their usage except for "laptop" which seems to me the generic term for now.

Here's a useful visualization thanks to Google Ngram Viewer: portable computer v. notebook computer v. laptop computer v. netbook

I just heard about another category called Smartbooks that seem to be somewhere between a smartphone and a netbook. They use RISC processors and a small (6"), high resolution (1024x?) screen, have a keyboard (thumbboard?) and run a 'proper' OS, e.g. Ubuntu Linux. They are starting to hit the Japanese market.

I think of a netbook as something that's cheap enough to be an impulse buy and small enough to fit in whatever bag you happen to have so that you will take it anywhere. It will be powerful enough for most web apps, but probably not much good for games. It's probably not going to be your main PC if you do more than surf. A laptop could be a main PC.

Laptops and Notebooks are synonymous. Netbooks are smaller and more portable and have longer battery life, they are generally used for simple things like browsing the internet and word processing and come equipped with an Intel Atom processor.

I once heard someone say that the term "laptop" is being avoided lest someone uses it on their laps, injure themselves through overheating, and sue the manufacturer.

Apart from what others have already mentioned ... laptops were usually considered somewhat larger then notebooks, due to their drive unit (FDD, CD/DVD ...). That difference nowadays has disappeared.
