Loads when computer first boots
Sits on top of hardware, is interface b/w hardware and software.
11. Device Drivers Interface b/w OS and hardware.

Services (Dae- OS programs that start when OS is loaded. They run in the background and wait

It's all combined into the URL.
**APACHE is most popular web server-can execute scripts for dynamic pages, use

*Also provides degree of anonymity, since IP address recorded is for proxy server
and not individual client.
*Can also be used to block requests to certain servers (i.e Facebook)
*Can reject responses that contain certain content (i.e "porn")
**SQUID is most common, but APACHE can also be used as proxy server.
17. Database Server Permits dB access across a network.
Performs tasks such as data analysis, data manipulation, security,and archiving.
May/may not store database itself.
**MySQL is popular.
18. FTP Server Hosts files and allows clients access to files.
Access is in form of uploading/downloading files.
Requires either user has an account or logs in as anonymous user.
19. File Server Computer with large hard disk storing files, but can also store software to be run
