Types of Personal Computers

Desktop

A Desktop computer is a version of a PC that generally as the name implies either can be placed on or near a desk. Desktop PC’s do actually come in a variety of types and sizes from ‘towers’ to slim-line PC’s. A Desktop PC is not intended to be portable so generally is kept permanently in one place.

Laptop

Laptop computers are relatively small computers and as a result are usually extremely light and therefore easily portable. Laptop’s can be powered by an internal battery or via the mains supply. Screen sizes can be anything from 14” to 17”. This clearly has an impact upon overall size, weight and battery life and as a result will effect portability.

Notebooks

Notebook PC’s are also known as Laptops but are often smaller and lighter. Screen size tends to be around 15.6”.

Sub-Notebooks

These are smaller, lighter and ultra-portable PC’s but still retain the same functions of a notebook but often have a longer batter life. Screen sizes tend to be around 10” to 13”.

Rugged PC’s

Rugged PC’s are laptop style PC’s but are strengthened and sealed against water/liquid for use in difficult and harsh environments. These are often use by organisations such as the Military.

NetBooks

Netbook Computers are small, extremely portable PC’s, normally with a screen size of approximately 10”. They generally are not as powerful as other portable PC’s and as a result lack some of the functionality.  That said, for very basic computing tasks and for ‘surfing’ the web and for email use, for which they were designed, they are fine. Do consider though that they lack an internal  DVD/CD though an external drive can be purchased separately.

Tablet PC’s

‘Tablets’ are a more recent innovation and a further development of the PC. They generally comprise of a single screen and input is via the screen (by touch) or stylus rather than by a keyboard. The purpose is mainly for web surfing and for media use such as viewing films and photos. They also lack some of the functionality of a traditional laptop or netbook but peripherals such as keyboard and external DVD/CD can be added. While their use was originally seen as limited to the consumer market, many businesses are now using them for presentations and where a really mobile device is required to input or request information e.g. health and medical records.

All-In-One PC’s

All-In-One PC’s are computers whereby all of the computers’ components are housed within the monitor. This generally makes for a more elegant looking desktop and a good compromise from a space saving perspective. Although available for a number of years, the downside was similar to that of a laptop or notebook in that because of size constraints, only certain components could be used. This resulted in difficulties when requiring an upgrade the system. However, manufacturers are taking a different approach and are often using standard desktop components and as a result upgrades are easier and prices are reducing. All-In-Ones are also being used for different purposes sometimes combing more a multi-media functionality such as touch screen technology as used in table technology.
