Zone Labs vs. Windows XP Service Pack 2 Firewall








Zone Labs vs. Windows XP Service Pack 2 Firewall




Windows XP computer users fall into two categories: those who have personal firewall software and those who do not. Knowing that the majority of computer users go without a firewall, Microsoft has included an internet security firewall into the latest XP update called Service Pack 2. If you had no prior firewall, the day you download the SP2 update is a happy day for you.

If you already have a personal firewall such as Zone Labs, McAfee or Norton, then a question arises as to which one you keep, because any computer repair store geek would say you should not keep both the XP firewall or your existing software because it has the dynamic Microsoft name behind it, or go with a more niche company for security such as Zone Labs.

What is this Firewall Thing, Anyway?

First, what is a firewall? A personal firewall protects your computer from malicious users by blocking unauthorized access. Who needs a firewall? The term “firewall” gives the impression that only large companies need a “wall” of “fire” to block attacks. You probably feel your computer is too small to attract an attack. But let’s not forget that hackers are hackers because they are students of behavior! They know that millions of people think they’re not targets and forego internet security. They build viruses to seek out such vulnerable computers, which can lead to a multitude of computer problems, not to mention identify theft.

Perhaps if firewalls were renamed, “personal identity insurance,” more people would realize the need to own it! So, does the Windows firewall do the job? While it will block incoming attacks, it will not block programs already installed on your computer from sending information out.

Many downloads you agree to will have spyware attached, and spyware often “phones home” with information about the user. Windows XP firewall will not stop this which is why computer experts suggest that for maximum protection you should go with a full firewall protection like the ones offered by Zone Labs, Norton and McAfee in lieu of XP’s.

If you use the internet, “There is over 90% chance your computer is infected with spyware” - Source CNN.

Just think about it. You probably have a t least one, if not more computers in your home. Most computers today have internet access. And if you receive email from others and surf to a couple of sites can you be almost completely sure you have some kind of spyware installed in your computer.

• It can record everything you do, allowing someone to see it later
• It can spy on you and send account information, passwords, credit card numbers and similar to a third party.
• It can “steal” files, pictures, videos and more from your computer

Some spyware will do just a few things and others everything from the list above, and more.

You must keep your computer clean from spyware or risk loosing personal information, financial information or even your private photos or family videos.

Run a spyware scanner regularly to clean out any spyware that may have sneaked their way into your computer. Do note that antivirus software (even the most expensive ones) have problems to keep spyware out. So get a good anti spyware software and use it!

No matter what the spyware's purpose really is, the bottom line is that at the very least it will cause you countless hours of problem solving and slow downs on your computer.

Scan your PC now to make sure it is clean. If you find anything, avoid using any credit cards or visit your bank until the PC is cleaned with a top anti spyware software.

Wireless Networks: How Do They Work?



Wireless Networks: How Do They Work?





Wireless networks use radio waves instead of wires to transmit data between computers. Here's how:

The Binary Code: 1s and 0s

It's well known that computers transmit information digitally, using binary code: ones and zeros. This translates well to radio waves, since those 1s and 0s can be represented by different kinds of beeps. These beeps are so fast that they're outside the hearing range of humans.

Morse Code: Dots And Dashes

It works like Morse code, which is a way to transmit the alphabet over radio waves using dots (short beeps) and dashes (long beeps). Morse code was used manually for years via telegraph to get information from 1 place to another very quickly. More importantly for this example, though, it is a binary system, just as a computer system is.

Wireless networking, then, can be thought of as a Morse code for computers. You plug in a combined radio receiver and transmitter, and the computer is able to send out its equivalent of dots and dashes (bits, in computer-speak) to get your data from here to there.

Wavelengths And Frequencies

You might wonder how the computer can send and receive data at high speed without becoming garbled nonsense. The key to wireless networking is how it gets around this problem.

First, wireless transmissions are sent at very high frequencies, which allows more data to be sent per second. Most wireless connections use a frequency of 2.4 gigahertz (2.4 billion cycles per second) -- a frequency similar to mobile phones and microwave ovens. However, this high frequency produces a wavelength that is very short, which is why wireless networking is effective only over short distances.

Wireless networks also use a technique called "frequency hopping." They use dozens of frequencies, and constantly switch among them. This makes wireless networks more immune to interference from other radio signals than if they transmitted on a single frequency.

Internet Access Points

The final step for a wireless network is to provide internet access for every computer on the network. This is done by a special piece of wireless equipment called an access point. An access point is more expensive than a wireless card for 1 computer, because it contains radios capable of communicating with around 100 computers, sharing internet access among them. Dedicated access points are necessary only for larger networks. With only a few computers, it is possible to use 1 of them as the access point, or to use a wireless router.

Industry Standards

Wireless equipment from different manufacturers can work together to handle these complex communications because there are standards which guide the production of all wireless devices. These standards are technically called the 802.11. Because of industry compliance with these standards, wireless networking is both easy to use and affordable today.

Wireless Is Simple To Use

If all this talk of frequencies has you worried -- relax. Wireless networking hardware and software handle all of this automatically, without need for user intervention. Wireless networking, for all its complicated ability, is far simpler to use than you might expect.

Why Do I Need Anti Virus Software For My Computer?



Why Do I Need Anti Virus Software For My Computer?





If you’ve recently purchased a computer, or are just learning about using email and the internet, you may have heard about computer viruses and anti-virus software. You may be wondering if this is something that you should be concerned about, and if so, what you should do about it. This article will attempt to answer these questions for you.

First, you may be wondering just what a computer virus is. Basically a computer virus is one of many types of small programs that install themselves on your computer without your consent. Usually they enter your program through an email, or while you are browsing a website.

When these programs run, usually without you knowing, they can cause all types of problems with your computer. Some viruses can be mildly annoying, slowing down your computer as they use your computer’s resources for another purpose. Others can be very dangerous, collecting your personal information and sending it to another party, or damaging your hard-drive.

True to their name, viruses are able to use your internet connection and email program and send themselves to the computers of other people you know, spreading themselves just like a contagious disease.

Because of this, just like the health of your body, when it comes to computer viruses, an ounce of prevention is worth a pound of cure. It is much easier to prevent viruses from entering your computer than it is to get rid of them and cure your computer once it becomes infected. This is why Anti-Virus software is important.

Once you realize that you need anti-virus software installed and running on your computer, you’ll have to choose which one to purchase and install. This can be a complicated process, but here are some tips to make it a bit easier.

First, check your computer to see if it came with anti-virus software. Many new computers are shipped with anti-virus programs already to go on them, you just need to turn them on. Check your instruction manual to see if this is the case with your computer.

Check with the vendor. If you purchased your computer from a local retailer, check with them to see what anti-virus program they recommend. They should be more than willing to help you and may even be able to provide you with a discount since you purchased a computer from them.

Once you have your anti-virus installed and running on your computer, be sure to contact the software’s support if you have any questions. It is also important to keep your software updated. Many of these programs will automatically update themselves when you are online. This is very important since new viruses are always appearing and you want to make sure your computer is protected.



When To Rent A Laptop Computer



                         When To Rent A Laptop Computer        






Most companies either lease or buy their computer equipment, but why or when should a company rent laptop or notebook computers?

Here are a few reasons to rent a laptop computer:

-If you need technology on short notice or for a short time, it is best to rent a laptop.

-If you need a large quantity of laptop computers for a training class, it is best to rent laptops.

-If your laptop computers are on back order but your staff isn't, it's best to rent laptops for immediate installation.

-If you need a wireless laptop computers for travel and all your company laptops and notebook computers are wired.
People confuse computer renting with leasing.

Renting is short term in nature and is very flexible. Leasing, like buying is a fixed arrangement.

You can extend the rental or cancel at any time with no penalty. Leases can't be cancelled without a 'severe penalty'.

Renting laptops is totally flexible, requires no capital budget and can often be accomplished with a company credit card. For most companies, renting is as easy as getting office supplies.

Rental companies have expert computer technicians who deliver, install and test your laptop rental right at your office, training room, trade show booth, seminar, convention or conference.

Rental companies have everything you need and a backup plan if something unexpected happens.

Other reasons why businesses rent laptop computers include temporary offices, traveling executives and temporary employees.

Temporary Offices
Temporary offices can be made complete with rental laptop computers, printers, copiers and fax machines. The hardware will be configured to your company specifications and installed at any remote location in the United States or Canada.

Rentacomputer.com has set up temporary offices in hotel rooms, trailers, warehouses and convention centers. Temporary offices have been set up for State and Federal Government agencies such as FEMA, the FBI and the IRS. Also legal firms, television networks covering hurricane disasters, movie studios setting up "on location", and new building construction sites, corporate mergers and takeovers.

Traveling Executives
Traveling executives won't have to carry portable laptop computers through airports or other public transportation facilities. Executives can have technology, preconfigured and tested, waiting at their final destination! Traveling with technology is one hassle that can be easily avoided by calling a computer rental expert like a Temporary Technology Travel Agent.

Temporary Employees
Temporary employees need temporary technology. By renting laptop computers you can coordinate the installation and removal of computers, printers and other technology for any period of time specified. If you hire temporary employees, hire temporary technology too.

Next time you have a temporary or special need, consider renting laptop computer technology and technical expertise.






What You Should Know Before Buying Computer Equipment



What You Should Know Before Buying Computer Equipment







There are many factors to consider when deciding on which computer equipment to buy. The massive amount of choices can seem overwhelming. This guide can help you compare computer equipment features, and help you to examine and sift through the basic items before you buy a new computer.

If it is a desktop PC, laptop, discount/surplus computer, a refurbished computer or a computer accessory, this quick guide will help you to get the most for your money.

With computer equipment today almost any of them will adequately handle what most people need to buy a new computer for; word processing, basic office, internet surfing and email. Which you can buy for about $1000. or less! But if you are into digital videos, photo editing, music, or manage a large database you will need more than the basic Desktop PC or Laptop. This higher end computer will cost you around $1500-$2000.

(CPU) Processors:
There is always a lot of change in the computer market, but no matter what the upgrades there is always two basic choices to be made when purchasing computer equipment:
1) brand 2) speed. To buy a new computer that handles standard office and Internet tasks any processor will work.

Need more 'power' in your computer equipment? Then the Intel Pentium4 or the AMD Athlon XP (great for graphics and photos which use a lot of memory space) are for you.

If you buy a new computer one or two levels from the top you will only lose about five percent per tier performance but you can save a couple hundred dollars!

(RAM) Memory:
Memory is very important because optimum running of your computer equipment is dependent on enough RAM. The minimum amount should be 256MB, for better performance you should get 512MB. If you can afford to buy a new computer with more, you should. It's worth it because you can keep more applications open and it will easily handle memory hogs like Photoshop and music applications!

Monitors:
When buying computer equipment look for a monitor that is at least 17" with a resolution of 1280 by 1024 pixels. A Desktop PC with a 19-inch monitor gives you 20 % more screen area. If you can spend $300-$450 on a monitor when you buy a new computer you might want to get a 15" LCD because it has the same viewable area as the 17" CRT and takes up much less space.

Hard Drives (storage):
Most hard drives sold today will provide more than enough storage. The basic computer equipment comes with 40GB or larger, which is plenty for most tasks. But for working with graphics, video, music, or large databases 80GB should be the minimum you settle for. 7200-rpm drives give better performance. But for the best performance get a computer with 8MB of cache.

Warranty and Tech Support:
A one-year warranty on most computer equipment is enough, because most problems seem to happen in the first year. If you want you can get an extended two to three year warranty for around $150. to $200. If you buy a Dell you can get priority call routing to tech support for a year for only $39.





What kind of processor do you need on your new Desktop PC?



What kind of processor do you need on your new Desktop
PC?






If you plan to do basic office work on you new Desktop PC or the usual Internet stuff;
surfing and email, any processor will work for you.

You say you need a Desktop PC to work with graphics, Video, Music, or large databases?

Than on your new computer you really need more power then the basic PC provides. AMD Athlon XP or Intel Pentium4 is your best bets for this kind of work. Either will support the most demanding work. Bargain price computer equipment with either kind of chip with fast speeds can be found.

For Desktop PCs Intel has a newer motherboard chip for its Pentium4 and Celeron. With the higher speed front side bus, data moves more quickly from the processor to the system memory. You can find these boards on Intel's 850 and 845 models. Just check the front side bus speed to make sure you are getting the right one before you buy computer.



What is a refurbished computer?


What is a refurbished computer?




Why buy 'new' computer equipment when you can get the same refurbished computer at up to 80% savings and there is no difference in the quality or warranty? Statistics show that people who have already bought a factory refurbished computer will never buy 'new' computer again! Manufacturers are so sure about there refurbished computer equipment that they offer the original warranties.


Exactly what is considered factory refurbished computer equipment?

A lot of things can be labeled factory refurbished. So frivolous are some that it's silly enough to make you laugh! Consumer laws prevent manufacturers from selling anything considered factory refurbished as new, so the second consumer gets the best deal and its just like a new computer!

For example, most major retail stores offer a 30 day money back guarantee on their computer equipment and some consumers take advantage of this. So when the new computer is returned, the manufacturer inspects the product and repackages it like new. But it can't be sold as new now so you get a great price with the original warranty, now its considerd a refurbished computer. Other reasons may be the box was damaged in shipment and so it was returned, a slight defect, the defective part is replaced by the manufacturer, tested and then repackaged just like new. Maybe a minor cosmetic blemish on the casing that was corrected. Demonstration units are also considerd factory refurbished computers. They are also inspected, tested and repackaged. The box was simply opened or brand new items that have been overstocked are also labeled factory refurbished.

Its hard to tell the history of each and every refurbished computer item but what ever the reason for the refurbished label you can be sure that the computer equipment has been inspected and serviced by the manufacturer then tested and repackaged to meet original product specifications, just like a new computer. And like I said before, all computer equipment merchandise is warranted by the original manufacturer unless otherwise specified.

Why buy a refurbished computer?
Well, to save MONEY! Why not get the best value while getting the exact same computer equipment? Also, you get the original manufacturers warranty and get a much, much lower price on your new computer.

Now with refurbished computer equipment you can afford that item which has been just out of your reach because it cost too much. And you will get the same performance! Actually refurbished items have a much lower defect rate than new ones. Only one in ten units that come back for repair is usually a factory refurb! That is because they are closely tested before they are sold. The only difference you may notice is a little label on the outside of the box or simply a brown box. So think hard before your purchase, are you shopping smart?


What Is Adware?


What Is Adware?



Adware is one of many "malwares" or malicious software programs that are unknowingly installed on your computer when you visit online sites and download freebies. When you use share files or visit sites with free downloads of wallpaper, videos, or music, some of these sites will send along adware software with your download.

These malwares are a rapidly growing threat to all computer systems. It is estimated that in the first three months of 2005 over 80% of computer users had some type of malware software program running on their computer, without their knowledge.

Although it is much less a threat to your computer and information than spyware is, what adware will do is cause pop up banners and advertisements to appear on your computer. These advertisements are displayed on your computer no matter what program you might be using. What the people who place this type of nuisance software on you computer say is that adware advertising helps them to recover costs and allows them to offer you those freebies you want.

What you want to do to stop adware from appearing on your computer is to first run an anti-adware program. Run this program on demand regularly. Along with an anti-adware software program run your regular computer virus scan on demand also.

Check the security level on your computer. You security level setting should be at least medium to help protect you from unwanted downloads.

Do not download free files from the internet, period. When downloading any software read the end-user license agreement. Some of these agreements will state that when you download their software you are also agreeing to accept a downloaded spyware that may be placed on your computer at the same time.

Be aware of threats to your computer, and your personal information.


What are Rackmount Computers



What are Rackmount Computers?



Rack mount computers are essentially computer servers. Computer servers are not the ones you play games on or send emails to your friends with.

Servers perform a small number of specialized operations, some as little as a single operation, but they have the ability to perform it millions of times over and over again, quickly and flawlessly. And when one server is no longer adequate to handle the volume of transactions that a business may require, other, bigger, more powerful servers are needed. When the new servers arrive, they are networked into the system and to save space, are mounted on racks.

When the business with the servers is a steel company, or an automobile manufacturer, industrial rack mount computers are the standard. Stored in rugged steel frames, stackable in standard 19-inch racks, industrial rack mount computers are used for database servers, web servers and networks. Furthermore they are also quite commonly used in laboratory and workshop environments.

Linux is a special operating system that is basically a version of Unix, which has become the foundation of the Internet. When ISP’s like AOL and others came into existence, the amount of servers they needed to accommodate millions of customers eager to surf the web was staggering. In order to make space for that amount of computers, a special rack mounted unit was created to hold the Linux servers. Dubbed the Linux Rack mount Computer system, it became the choice for all of the new Internet businesses all over the world. Soon after, manufacturers of the Linux Rack mount Computer racks where inundated with orders and quickly fell behind schedule.

It took a while for Intel to catch up with it’s rivals, but once they did, the Xeon Rack mount Computers quickly overtook everyone else in the field and became the gold standard among all of the rack mounted computers being installed.

These benefits and values of surplus computers were traditionally available to only large volume commercial buyers, dealers, and corporate level buyers. But now discount computers are also sold retail so you can get all the benefits too.

The sellers of surplus computers and discount computers are committed to offering

tremendous savings to you, the retail customer. Desktop PCs, laptops, notebooks,
barebones, whole computer systems, computer accessories, everything in computers you can find in surplus and discount computers.

Repackaged products are sometimes sold as surplus computers or discount computers but
they are always evaluated, tested and quality assured, fully functional and repackaged for shipment.

Also, sometimes sold as surplus computers or discount computers are open Box products
which are retested, quality assured, fully functional and complete. The customer can expect original manufacturer packaging.

Understanding the Components of a Home Network



Understanding the Components of a Home Network



Home networks are becoming more common. People want to be able to share a single broadband Internet connection to several computers in the house. There are many different devices that you can use to make up your home network. If you have never heard network terminology device names like router, hub, etc may seem confusing.

The purpose of most of these devices are to control how the network passes around information. This information is sent in the form of "packets". I will refer to the term packet several times in this article. It simply means the data that the network is transporting. I will now explain the purpose of the major components of a home network.


What is a Hub

A hub is a device that has several Ethernet ports on the back of the device. One of these ports will likely be labeled “Uplink”. This port allows you to connect multiple hubs together, if you run out of ports on your hub. If you do not have an uplink port on your hub, the hub can not be easily extended if you run out of ports.

A hub is a device that attaches multiple computers on an Ethernet network. If you have a number different computers that you want to connect together, you could connect each to the hub. Any packet that is sent out by any computer on the network will immediately be transmitted to the other computers. Each computer will determine if the packet was really intended for it, and filter out packets that were intended for other computers.

You really should not use a hub in a modern home network. You should always use a switch in place of a hub. Switches will be discussed in the next section.

What is a Switch

A switch is a device that has several Ethernet ports on the back of the device. One of these ports will likely be labeled “Uplink”. This port allows you to connect multiple switches together, if you run out of ports on your switch. If you do not have an uplink port on your switch, the switch can not be easily extended if you run out of ports.

A switch serves the same function as a hub. It allows you to connect multiple computers together, so that they can exchange packets. However, a switch is much more efficient than a hub. A switch will only send Ethernet packets to the computer that the packet was intended for. Because of this you should always use a switch in place of a hub.

What is a Router

A router is a device that has several Ethernet ports on the back of the device. One of the connectors will be labeled WAN. You should connect the WAN port to the Ethernet connection on a broadband source, such as a cable or DSL modem. The other ports on the router can be connected other computers or switches/hubs that will share the WAN connection.

Routers allow you to share your broadband connection with multiple computers in your house. Rather than connecting your computer directly into your cable or DSL modem you connect the router to the cable or DSL modem. Now any computer that you connect to the router will have access to the Internet.

If you run out of ports on your router you can always connect an additional switch to the router. To connect a switch to a router simply connect the switch’s "uplink" port to one of the routers Ethernet ports. Of course, don’t connect to the router’s WAN port. The WAN port should only be connected to something such as a cable or DSL router.

Some routers come with additional features installed. Most routers also include a firewall. Firewalls are discussed in the next section. Some routers will also include a wireless access point (WAP). The WAP allows you to use wireless devices, such as wireless laptops, with the Internet.

What is a Firewall

A firewall controls traffic flow between your network and the Internet. A firewall can be either hardware or software. Windows XP SP2 or higher includes a software firewall. A hardware firewall is included with most routers.

A firewall is a very good idea. It can protect you from inbound virus attempts. By inbound virus attempt I mean other computers that will connect to your computer and attempt to infect your computer. You do not want to run a computer directly connected to the Internet, without a firewall. There are just too many other computers out there that can connect and infect you without you even noticing.

What is a Network Attached Storage (NAS)

A network attached storage device is s device that allows a hard drive to be shared across the network. This hard drive is NOT attached to any of your computers. It is simply made available by the NAS. This can be a convent way to add a hard drive that can be accessed by several computers on your network. The other common way to add a network hard drive is to simply share a folder on one of your computers. However, with the NAS, you do not need to keep one of your computers on at all times.

There are two types of NAS commonly available. The first type comes with a build in hard drive. The second accepts a USB or Firewire external hard drive. The advantage to using a USB or Firewire hard drive is that you can upgrade the hard drive if it ever were to become too small.

What is a Print Server

Just like you can buy a device to allow you to share a hard drive, you can do the same with a printer. A print server connects directly to your printer. Your printer is then shared to all of your computers on the network. This is convent because you do not need to leave the printer hooked to a computer, which must be turned on to print.


Conclusions

As you can see there are many different components. Perhaps the final component that I have yet to mention is the cable. These components are connected together with CAT5 Ethernet cable.

You are now ready to pick out the components for your home network!
