Laptops Notebooks Netbooks

We all know what laptops are don't we? Or do we really understand what we are buying?

At SMC Computers Pooraka, we have available, a large range of Computers, Laptops, Netbooks, Notebooks and Desktops, of many different styles to suit many different needs.

The terms "laptop" "notebook" "netbook", are usually considered by most consumers, to refer to the same thing, however these terms can, and most time do refer to a number of different classes of small portable computers, some of which are outlined below.

  • Full-size Laptop – A laptop large enough to accommodate a "full-size" keyboard (a keyboard with the minimum QWERTY key layout, which is at least 13.5 keys across that are on ¾ (0.750) inch centers, plus some room on both ends for the case). The measurement of at least 11 inches across has been suggested as the threshold for this class. The first laptops were the size of a standard U.S. "A size" notebook sheet of paper (8.5 × 11 inches), but later "A4-size" laptops were introduced, which were the width of a standard ISO 216 A4 sheet of paper (297 mm, or about 11.7 inches), and added a vertical column of keys to the right and wider screens.
  • Netbook – A smaller, lighter, more portable laptop. It is also usually cheaper than a full-size laptop, but has fewer features and less computing power. Smaller keyboards can be more difficult to operate. There is no sharp line of demarcation between netbooks and inexpensive small laptops; some 11.6" models are marketed as netbooks.
  • Ultra-thin Laptop – A newer class of laptops which are very thin and light.
  • Tablet PC – these have touch screens. There are "convertible tablets" with a full keyboard where the screen rotates to be used atop the keyboard, and "slate" form-factor machines which are usually touch-screen only (although a few older models feature very small keyboards along the sides of the screen.)
  • Rugged – Engineered to operate in tough conditions (mechanical shocks, extreme temperatures, wet and dusty environments).
  • A desktop-replacement computer - is a laptop that provides most of the capabilities of a desktop computer, with a similar level of performance. Desktop replacements are usually larger and heavier than standard laptops. They contain more powerful components and have a 15" or larger display. They are bulkier and not as portable as other laptops, and their operation time on batteries is typically shorter. They are intended to be used as compact and transportable alternatives to a desktop computer.
  • A subnotebook or ultraportable - is a laptop designed and marketed with an emphasis on portability (small size, low weight and often longer battery life) that retains performance close to that of a standard notebook. Subnotebooks are usually smaller and lighter than standard laptops, weighing between 0.8 and 2 kg (2 to 5 pounds). the battery life can exceed 10 hours when a large battery or an additional battery pack is installed. Since the introduction of netbooks, the line between subnotebooks and higher-end netbooks has been substantially blurred. To achieve the size and weight reductions, ultraportables use 13" and smaller screens (down to 6.4"), have relatively few ports (but in any case include two or more USB ports), employ expensive components designed for minimal size and best power efficiency, and utilize advanced materials and construction methods. Most subnotebooks achieve a further portability improvement by omitting an optical/removable media drive; in this case they may be paired with a docking station that contains the drive and optionally more ports or an additional battery.

The basic components of laptops are similar in function to their desktop counterparts, but are miniaturized, adapted to mobile use, and designed for low power consumption. Because of the additional requirements, laptop components are usually of inferior performance compared to similarly priced desktop parts. Furthermore, the design bounds on power, size, and cooling of laptops limit the maximum performance of laptop parts compared to that of desktop components.

Some laptop components (optical drives, hard drives, memory and internal expansion cards) are relatively standardized, and it is possible to upgrade or replace them in many laptops as long as the new part is of the same type.

Laptops, like desktops, have there advantages and disadvantages.



  • Portability - a laptop can be used in many places
  • Productivity – Using a laptop in places where a desktop PC can't be used.
  • Immediacy – Carrying a laptop means having instant access to various information.
  • Up-to-date information – using a single laptop files exist in a single location and are always up-to-date.
  • Connectivitya laptop can have easy Internet and local network connectivity while remaining mobile.
  • Size – Laptops are smaller than desktop PCs.
  • Low power consumption – Laptops are several times more power-efficient than desktops. A typical laptop uses 20–90 W, compared to 100–800 W for desktops.
  • Quiet – Laptops are often quieter than desktops, due to use of fewer and slower cooling fans.
  • Battery – a charged laptop can continue to be used in case of a power outage and is not affected by short power interruptions and blackouts.



  • Performance - The upper limits of performance of laptops remain much lower than the highest-end desktops

  • Upgrade-ability - is very limited compared to desktops, which are thoroughly standardized
  • Durability - Due to their portability, laptops are subject to more wear and physical damage than desktops.

  • Security and privacy - Because they are valuable, common, and portable, laptops are prized targets for theft.

So there you have it, Oils may be oils, but Laptops are not just laptops. A Laptop is a great multi-purpose machine. By combining great value with innovative multimedia and communications technology, you can take high definition entertainment to new levels. By Combining superb wireless connectivity and an enviable design, and providing the perfect balance between performance, mobility and size, a big screen notebook that has all the features and performance you need will power through your everyday tasks.

There is a multitude of laptop brands and manufacturers, and several major brands, offering notebooks in various classes, which can make choosing a laptop, a nightmare. At SMC computers, we can help you to compare the different brands and classes, and help you to choose a laptop that is right for you.
