Dialup OR Broadband?
Broadband (DSL Internet or Cable Internet)
Dial Up Internet The fundamental difference between dialup and broadband Internet connections is the manner in which the connection is made from your PC to the Internet. A dialup service connects to the Internet through your phone line. The modem in your PC "calls" an Internet Service Provider (ISP) and connects with a maximum speed of 56,000 bytes per second, better known as a 56K speed connection. Each time your PC dials into the ISP, it is assigned an Internet Protocol (IP) address, which you can think of as an "Internet address." A different, unique IP address is assigned at the beginning of each visit so that the ISP can recognize your PC and make sure you can send and receive email, surf the Internet, and so on; basically, this address lets your ISP know where to send the information you are requesting through your modem. In terms of hackers, in order for someone to gain access to your computer, it would be necessary for them to know your IP to successfully do so. The fact that your IP address constantly changes essentially makes your Internet connection more secure.
Connection speed and price are two important considerations when choosing between dialup and broadband. Dialup connection speeds make it more difficult to view certain types of media, such as video, and it can take much longer to download and open email attachments, play online games, and so on. Although the slower connection speed is a disadvantage for dialup users, there are also a few advantages to using this type of connection, which include lower monthly charges and a higher level of security. The cost difference is obvious when comparing the $20-30 per month subscription fee for dialup and the $50-60 per month subscription fee for most broadband services. In terms of security, because the connection is not "always on" and because you are assigned a different IP address each time, it is slightly more difficult to be attacked over the Internet, although nothing is ever fool proof and risks still do exist. The advantages of a broadband connection can sometimes outweigh some of the disadvantages. The increased connection speed allows for ease in initial connection, duration of connection, no additional phone charges that may apply in dialing into an ISP, and variability of Internet use, such as an increase in allowable file viewing size. However, if you do choose a broadband connection, you'll need to purchase a firewall-which we'll learn more about later-to keep your computer "invisible" to the outside world.
