Security updates patch vulnerabilities that may be exploited by malware and help keep users and your data safe. Your system is no longer protected, as you will no longer have a supported operating systemows, and will no longer receive regular security updates to protect your computer from malicious attacks. You would not want to use an unsupported Operating System to access the internet.
The processor speed determines how fast or slow the computer runs, it is measured in Hertz, generally in gigahertz (GHz).

2) Laptop battery (add the $90 - $120 to your cost.)
Add the cost of the AC adapter, if not included (cost around $70.). If you are going with an older OS you want to make sure you are going to get System CD or diskettes. Applications:
>Operating System (OS), if you want internet access you would want Operating System.
You would want the CDs for (OS, Word, etc.), to be able to reinstall the software, if the hard disk crashes or you have a software problem you can reload the program again. If you get the manuals the CDs or diskettes are usually in them. >/>
