A common misconception I run across often is that getting a faster Internet
connection will make the computer faster. The Internet is just one of many
functions a computer performs. Whether you connect via a phone line, DSL,
or cable has absolutely NO bearing on how quickly the computer boots up or
opens a particular program.
A faster Internet connection will allow you to receive large email
attachments faster, surf the web faster, and download updates faster, but
it does nothing else for speeding up other computer functions. If your
computer feels slow, that can be due to one or more factors including; not
enough RAM, too many temporary files saved on your computer, a “dirty”
startup, and/or spyware and viruses.
