3. I think the intended users were both home and business to not only make a wireless system for printers and other office devices but to reduce energy. It is a reflection of short range, high bandwidth applications.

The transfer rate from WUSB is 480 Mbps (60 MB/s) if the device is within 3 meters (9.84 feet) from the PC.

REAL PROBLEM 11-1: Selecting a Color Printer for a Small Business

1. HP Office Pro K8600 - Ink Jet
Xerox Phaser 6125
HP Color Laser Jet CP6015dn
2. I have instant messaged both Xerox and HP and the only maintenance is changing the ink cartridges and the drum if its the Laser Jet.
3. See Print out.
4. All the costs below include the cost of the printer
5. Advantages for the Office Pro K8600 is the cost and the quality of the prints. When you look at the cost on an annual basis is the lowest. Disadvantages are that it only has one paper tray which and the monthly max is a bit under the 8,000. Therefore the longevity may not be there and is not network capable. The HP Color Laserjet CP6015dn has the longevity (with a monthly duty cycle of 175,000) therefore the a great buy. Faster machine than the other two and the most memory. The annual cost is just over $1,000 over the Office Pro, but is laser quality for only pennies a copy more. Network capable. Disadvantages upfront cost is high as it retails for just under $4200. The Xerox Office Phaser 6125 is a laser printer with great quality. Its upfront cost is low and the only maintenance is changing the toner. It is network compatible and has a mid range of 40,000 maximum pages per month. Disadvantage is that it is the most expensive on an annual basis.
6. I recommend the HP Color LaserJet CP6015dn. Its an expensive upfront cost, but you will not be replacing the unit every year because it can handle the large amount of prints. There is low maintenance and its well worth the extra $1000 for the time it will save on the speed of the copies as well as the quality (laser vs ink jet). Honestly, if you look at the annual costs against the upfront costs there is no reason not to get the quality of the better printer with more possibilties

This is my Email hoax that I received today. I tried several of the web sites in the book but none showed in detail the email fraud I received.

I did however find it when I did a google search for Angela White

Hello,

My name is Barrister Thomas Harry. I am the attorney of Late Mrs. Angela White, who died in London UK. I have a business proposition for you.

Before the death of my late client, she lodged huge amount of money in a security vault/company here in Europe, amounting to Ј3,000,000 (three million pounds) that is $6,000,000.00 (Six million dollars). And she left behind strict instructions on secrecy and top confidentiality of her funds in the security company. And the only person aware of the funds is me been her attorney. And she left instructions with the security company that, it is only her lawyer that knows about the funds in their custody.

Unfortunately, Mrs. Angela had no next of kin as she had no children and she didn't appoint any inheritance. It is on this note,that you come in, I would like you as a foreigner to stand as the next of kin whom I will appoint and notify the security company that you are the actual next of kin appointed by Mrs. Angela White before her death. Please, have nothing to worry about, as I will commence processing all legal documentations certifying you as the Sole-Beneficiary to Late Angela White, Be rest assured that all documents will be processed according to the law.

If you agree to do this with me, we shall both share the total amount of $6 million USD 40/60 %, which means $2.4M( Two million four hundred thousand dollars)for you, while $3.6M (Three million six hundred thousand dollars) would be mine. If you oblige then kindly send me your full name, Age, address, telephone and country, in order for me to prepare the necessary documents for the funds to be released to you.

Kindly note that this transaction requires maximum secrecy. Kindly response to me ( thomasharry45@inMail24.com). I await your response.

REAL PROBLEM 10-1: Cleaning Your System of Malware

I, as you know, have a new computer for this class. I have Norton and ran it for this assignment and came up with no infections. I also went to the Malicious Software Removal Tool from Microsoft: http://www.microsoft.com/security/malwareremove/default.mspx - please note this takes roughly 45 minutes.

If something had come about I would then check to see if there were any start up errors. If there were I would go into the MSconfig and see if the Dll is launched. I could then go and delete this fine using the CMD and delete the file. Also make sure my recycle bin is emptied. I would then purge restore points and clean the registry.

REAL PROBLEM 9-1: FIREWALLING YOUR HOME NETWORK

The solution here is to purchase a Wireless Router with the built in firewall protection. I would recommend that the wireless router (roughly $50) be installed to the cable modem. The two computers can be connected to the router (most can hold up to 4 additional users by patch cables). This would eliminate the need for a host computer.

Configuring the software and firewall with the router is the key to success with intrusions. This will also take care of the daughter and her laptop needs. Most laptops now have built in wireless connection, but USB or network adapters (recommend the same brand as the router for success!) for roughly $40. So for under $100 you can have everything needed to have a secure internet connection - without any additional software or mess.
