What is the difference between a notebook and a laptop?
There is no difference. These terms are interchangeable and they refer to the same thing - a computer system that is portable. Laptop is the accepted term in South Africa and is used more often than notebook.*

Which processor / CPU?
Purchase the best processor you can afford. Dual core and quad core processors outperform single core processors on multi-threading programs. For gaming, speed is still a deciding factor and single core processors that run at higher speeds will outperform Dual and Quad cores, although some games already take full advantage of multi-core processors.

How much memory / RAM do I need?
The more memory your machine has, the better it will perform. 32 bit hardware has a limitation when it comes to memory. The maximum amount of usable memory is approximately 3 Gigabytes. The 32 bit version of all Microsoft Windows caps the memory at 3.12GBytes irrespective of how much more is added.

There is no workaround as this is a hardware limitation. To use more memory, a 64 bit processor and operating system is required.

MS Windows Vista requires a minimum of 2GBytes to run smoothly.

Which operating system do I select?

Linux is an open source operating system, making it the cheapest operating system. Linux is not recommended for beginners.
