There not really much difference between a Netbook and a low specification Laptop.
When comparing a typical laptop to a typical netbook the netbook will have a lower power processor, less RAM, smaller hard disk etc. The netbook probably won't have an internal DVD/CD-ROM drive, and may also lack an ethernet port (using a wireless connection instead) and other ports - like memory card readers or external video connections etc.
Netbooks are fine for low power tasks like browsing the web, email and simple office type tasks but probably won't be much good for, say, advanced multi-tasking or editing video.
Hope that helps.
