New Technology In my research, I am focusing on the new technology dealing with computers. This technology includes CD writers, DVD players, digital cameras, and cable modems. I will describe each technology and then how it will effect today’s society.

Technology is the way of the world now, so improving technology helps to improve the society. CD writers are the wave of the future. What is a CD writer one may ask? A CD writer is simply a technology device that allow one to record information onto a CD and then the CD is used for storage instead of using the hard drive. Why would you want something that records CDs? CD-RWs are a great storage device.

You can create valuable backup volumes for your important files and programs, share your work with friends and colleagues in an easy-to-manage and familiar format, and make mixed audio CDs from CDs in your personal collection or even from old tapes and vinyl. How much does something like this cost? Below you will find a chart showing different CD writers available, the cost, and other valuable information. CD writers are not for everybody, but they are worth checking into.

DVD stands for digital video drive. Recall that VCR sitting in your den? VCRs are quickly diminishing as DVD players are beginning to take over. Why the DVD player? A DVD player has better graphics then does a VCR. The DVD also takes up less space then videotapes since they are on a CD. With the DVD player, one can play games or simply watch movies from their very own computer. Prices for DVD players vary depending upon brand, speed, and other determining factors.

DVD players range between $179.94 to $1,299.95. As well as DVD players for the computer, DVD players for the TV are becoming available. Some people will want a DVD player for their computer while others will want it for their TV and still others will stick with their VCRs for the time being. Below you will find a list of available DVD players and their cost.

If you think about the future, what is the first thing that comes to mind? Well, in the minds of most people the word computer or Internet will come to mind. Since the introduction of PC’s in the late seventies and early eighties, the technology involved in computers has grown exponentially. The internet, which came into widespread use only five or six years ago has grown unimaginably. Anybody can find virtually anything they want over the Internet. The first way to access the internet was through dial up telephone modems brought through ISP’s such as Prodigy, AOL, Compuserv and many other providers.

These providers were slow and sometimes you couldn’t even get through the busy phone lines. the phone modem industry has grown greatly since then, but it still has its flaws. ISDN’s have become popular in the business world and provide better service than telephone modems, but they also have their flaws. The wave of the future as far as Internet access is concerned is cable modems. Cable modems are faster, more efficient, more cost efficient and easier to use than any other Internet access that’s ever been introduced. WHAT IS A CABLE MODEM? A cable modem is a device that allows high speed data access (such as to the Internet via a cable TV network.

In other words rather than running the Internet through the telephone, it will be run through cable TV. HOW DO CABLE MODEMS WORK? There are five main components to the operation of cable modems: 1. the headend 2. the trunk cable 3.

the distribution cable in the neighborhood 4. the drop cable to the home and in house wiring 5. the terminal equipment. It’s really a fairly simple process. A cable modem network is described as a tree and branch network. This means there is a main station (headend that has a trunk cable that distributes feeder cables to all of the neighborhoods.

These feeder cables branch off into drop cables that go into the homes of the individuals, where it is then wired to the terminal equipment. WHAT ARE THE ADVANTAGES? There are many advantages to using the modem over a phone modem or an ISDN connection. Ther first advantage and probably the most popular and important to the average consumer is the speed of the modem. How many times have you found yourself staring at you monitor, waiting for your computer to download a file. Those days are over. A good modem in today’s computer is 56Kbps.

The cable modems that are being manufactured now range from, at the low end, 500Kbps to, at the high end, 36Mbps. Most of the cable modems being produced right now operate at 1.54Mbps upstream to 10Mbps downstream. Transfer Rate for a 10Mb File: MODEM SPEED/TYPE TRANSFER TIME 9.6Kbps telephone modem 2.3 hours 14.4Kbps telephone modem 1.5 hours 28.8Kbps telephone modem 46 minutes 56Kbps telephone modem 24 minutes 128Kbps ISDN connection 10 minutes 1.54Mbps T-1 connection 52 seconds 4Mbps cable modem 20 seconds 10Mbps cable modem 8 seconds This is a brief example of how fast a cable modem is in comparison to the connections we use today. This doesn’t even include the 36Mbps cable modem that has been introduced. Another advantage is the imporved service that the cable modem provides over the traditional phone modem.

The bandwidth of the cable is 6MHz, which is much larger than that of a telephone modem. This allows more Internet lines to be run through it. Most of the producers of cable modems can ensure that no more than 80% of the lines are being used, and if that much is being used then they can open up more unused lines. This would make it where the user would never get a busy signal as you do sometimes with telephone modems.

Also the cost of the cable modems, especiall in LAN’S AND WAN’s would be much lower. With telephone modems and ISDN connections, consumers are charged for every minute they are online. With a cable modem there is a flat, monthly rate, usually around $40 a month. THE DISADVANTAGES? Are there any disadvantages to this? Well there are a couple of minor disadvantages. Since the network would be a tree and branch network, any interference in the network would be combined with all other noise and could make for a noisy connection, and with the large bandwidth of the network there will be a little more noise.

However, the producers have done something to fight this. They have developed two main modulation schemes, QAM, which sends data at up to 10Mbps and QPSK, which works at up to 36Mbps. The QAM is more popular right now, because it minimizes the noise produced by the network. While the QPSK is much faster, it is more robust scheme than higher order modulation techniques in a noisty environment. Also since there are so many different frequencies inside the cable, if a noisy connection is detected, it can automatically be switched to one with minimal noise. We may just have to settle for our cable modem being 1000 times faster rather than 3000 times.

COSTS? The big question that everyone is going to ask is, how much. How can I get this kind of revolutionary service at a price I can afford? You have to look at it overall. It costs around $200 for the modem itself and about $100 to install it. These prices may sound high but when …
