Mac Minis and Its Security
Apple builds some sexy hardware and software, but many people prefer to use their stuff for their work and research because it simply allows more productivity and is more pleasurable to work with.
Mac minis: Like the iMac G5 January 2006, the Intel iMac April 2006, and the Mac Book Pro May 2006, the new Mac mini includes Apple’s Front Row software and the Apple Remote, which gives you the ability to control the playback of movies, photos, and music without having to sit in front of a keyboard.
The minis now have Serial ATA hard drives, which offer 1.5 times the bus bandwidth of the previous ATA drives. Apple retained the single FireWire 400 port but doubled the number of USB 2.0 ports on the back from two to foura welcome addition. Earlier models were practically unusable without adding a USB hub to gain access to extra ports.
When it comes to graphics-intensive 3-D games, our tests of the Intel-native version of Unreal Tournament showed disappointing frame rates of 12.2 per second for the Core Duo and 10.4 per second for the Core Solocompared with 14.5 and 13.9 for the 1.42GHz G4 mini and the 1.25GHz G4 mini, respectively.The Mini comes pre-installed with Apple’s Front Row software. This is an extremely slick interface that lets you browse your iTunes and iPhoto libraries using the Apple remote control.
The new Mac minis take a different approach to graphics than their predecessors. Last year, Apple trumpeted the ATI Radon 9200 graphics chip with 32MB of dedicated DDR memory instead of a graphics structure that borrowed its memory from the system. But in the new minis, that’s exactly what Apple uses. The mini’s integrated graphics feature is a mixed bag, though, since it adds to and subtracts from the previous graphics features.
In January 2005, Apple introduced the Mac mini as a low-cost Macand it still is, even though the price of admission has increased by 0. The Mac mini Core Duo’s built-in improvements and performance boost are worth the higher cost. And although the Core Solo model clearly underperforms compared with the Core Duo in almost every respect, it’s still a good entry-level Mac for the money.
As computers become an integral part of everyday life, security becomes increasingly vital. Securing your Mac is obvious, but far more important is the data that it contains.
If somebody steals your Mac they can spend a lot more time trying to gain access to the data on it. The techniques that you use to deter the casual thief will generally only take a few minutes to overcome, enough to stop someone who wanders by your desk when it is unattended but not enough to be an inconvenience to you when you are using the computer.
For home users the cost of replacing a lost computer is a much bigger issue but it is still important to consider what information the thief will have access to if they manage to get their hands on an unsecured Mac.
You need to take strict security measures all of the time as it is just as easy to leave it in a taxi or have it taken from your table when you pop to the toilet as it is to have it stolen from your home or office.If you are wanted to know the everything about the Mac world that just log on to these websites.

External Mini USB 2.0 4-Port Hub 
Mini USB 2.0 4-port hub is the travel hub for at home or on the road. It allows you to connect 4 USB devices such as mice, digital…
Information about a USB Hub?
Since the mid 90′s we have seen the birth and growth of a connective technology called Universal Serial Bus (USB). Originally designed to connect computers and telecoms equipment, it has slowly become the primary means of connecting a whole host of other devices and has made significant contributions to today’s IT world.
The sheer number of USB products on the market today is just staggering, from mice and keyboards, modems, external hard drives to USB fans, lights and coffee cup warmers! Most external computer related devices today connect to a computer via a USB port. So it’s no wonder that before long, most computer users find themselves wondering what to do when the USB ports (sockets) on their computer are all used.
There are two solutions to the problem, constantly plug and unplug connectors when swapping between USB devices, or invest in a simple, low cost device called a USB Hub. A USB Hub is a small unit with two or more USB ports, which plugs into an USB port on your computer, allowing you the freedom to connect more USB devices without disconnecting others. Expanding the number of USB ports of your computer in this way not only saves wear and tear on your USB ports and connectors, but also puts and end to all that clambering around behind your PC! Generally speaking, there are four types of available:
1. Internal USB PCI Card
An internal PCI USB Card needs to be installed by opening up the case of your PC and inserting a card into a vacant PCI slot on the motherboard, this type of USB expansion is not advised unless you are familiar with working with and inside computers. If you have the older USB1.1 and upgrade to USB2.0, your version of Windows will also need to be updated so that your PC can support USB2.0 functionality.
2. USB Hub (Non Powered)
An external non-powered USB Hub is a cheap and simple device that plugs directly into one of your computer’s existing USB ports and that’s all there is to it. These are usually very compact and so make ideal solutions for mobile users with laptops and for desktop users.
Be aware that some USB devices require a small amount of power through the USB port, usually mechanical devices such as printers, scanners, digital cameras and so on. This type of USB Hub may not be able to supply adequate power to these devices especially if you are using a few USB devices together.
3. Powered USB Hub
An external Powered USB Hub is also compact and plugs directly into one of your computer’s existing USB ports, so again there is no need to open up your computer to install it. The only difference is that the Powered Hub comes with a separate power supply that must be plugged into the mains socket, supplying the power to all the USB ports on the hub allowing ANY type of USB devices to function properly.
Most Powered Hubs come with a sensible length of USB cable allowing the Hub itself to be positioned in a more accessible place e.g. on top of your computer or on your desk, making plugging and unplugging USB devices much easier. This makes the Powered Hub the all round best solution for desktop computer users.
4. USB PC Card
If you use a Laptop and are on the move, you have an additional choice to the USB Hub, the USB PC Card also known as the PCMCIA USB Card. This device slots into the PCMCIA slot/port found on the side of a Laptop and instantly provides two extra USB ports without using up any of your existing USB ports on the Laptop.
This is the most popular solution for mobile Laptop users. When buying a suitable external USB Hub, consider the location of your computer’s USB ports. If they are located at the back of your computer or in an awkward position, you can make your life so much easier by using a USB Hub that comes with a USB extension cable, or by buying a separate USB extension cable. This allows the USB Hub to be positioned to a more accessible place for plugging and unplugging your USB devices.

The Difference Between Dsl and Cable for High-speed Internet Service
You timidly suggested to your nephew that you were considering a move to a faster form of Internet access. Perhaps you have heard the term “broadband connection.” He probably heaved a huge sigh of relief. “Finally!” he said. But when you asked for guidance on which service to choose, you soon were sorry you asked. In two or three short sentences, he left you behind, babbling in technical gobblydegook that you couldn’t possibly follow — when all you really wanted to know was, “What should I get?”
Breathe easy. We’ll explain what the options are for faster Internet connections (which is what’s meant by “broadband” or “high-speed Internet”), with just a teeny bit of “how it works” so you have some sense of what you’re choosing and why.
In doing so, we don’t expect that you want to become a computer wizard. All you want, we assume, is the ability to get the advantages of fast Internet access: a computer that is always connected to the Internet, that permits you to zip around Web pages faster than you imagined possible, and that opens up a whole new set of ways to waste time online. Oh, we mean, a whole new set of ways to be productive. Whatever.
Let’s start out with the key question, and then work our way back to the underlying issues.
Q: What should I get? DSL or Cable Service? Most technical people will give you all sorts of “this is how it works” answers, and they’ll talk about performance (that is, is DSL or cable service faster?) and setup (that is, how will you get your computer hooked into the modem?). There are differences between the technologies, and we’ll get to those in a moment.
But for someone who’s simply trying to find a simple and credible answer, the truth is that “fastest” is not really the most important issue. It’s just like choosing a car. Yes, auto enthusiasts discuss performance and 0-to-60 speeds and other things that matter primarily to other car aficionados. But if all you want is a car to commute to work, then what matters most is reliability, gas mileage, and the phone number of a mechanic whose work you trust. And affordable. It should be affordable.
In terms of high-speed Internet connections, that means:
1) Find out if you have a choice at all. In many places, you can get one kind of service but not another. (We’ll explain the reasons why in a little while.)
2) Choose a provider you trust. If you hate your phone company or if you are already irked with the cable TV provider, why add agony to your life? Choose the provider whose service you trust the most (or whom you hate the least, which may be closer to the mark).
3) When you check into pricing, be sure to find out about installation options. Many cable and DSL providers will come to your house or business to set up the network and Internet connection. If one provider does so and the other does not, your decision is easier. As with many things in life — such as garage door openers — it’s important to get your high-speed Internet service installed right in the first place, or it’ll never quite work correctly. It can be worth the expense to pay a professional.
4) If company-supplied installation is not an option, then ask your “local techie” — that same nephew who’s sure he knows everything — which type of service to get, and follow his advice. If you rely on family-provided technical support, then it makes sense to choose an option with which that family member is comfortable. Doing so avoids those nasty “I told you so” conversations over the Thanksgiving table.
5) Consider price as just one element of the equation. In most cases, the difference in cost is negligible. But your existing phone and cable company may be able to sweeten the deal; for example, some cable companies may offer a reduced price if you get Internet access, telephone services, and TV stations from them.
What — none of those things are about technology! Isn’t that the key issue? Shouldn’t I choose the one that’s better?
Yes, there are technical differences between the two kinds of service. There can be major speed differences. But in the real world, “convenience” is often much more important.
Q: What do DSL and cable services have in common? Both types of service provide an “always-on” connection. That is, they’re automatically connected to the Internet as long as the computer is turned on. You need not worry about busy signals or any connection/disconnection process.
Both are billed on a monthly basis, often on the same invoice with your phone or cable TV service.
Both work with your Windows or Macintosh computers without fiddling. They’ll also work with other operating systems, too. However, the typical high-speed Internet service technical support representative may be unfamiliar with the details of getting everything to work with your “alternative choice.” It may take extra expertise, and you may need additional help (that is, expect to buy the nephew a nice dinner).
In most places, DSL and cable access cost about the same.
Q: How is Internet speed measured… and to what degree does it matter? When computer techies talk about Internet connection speed, it’s generally in mbps: millions of bits per second. This can be confusing since everything else in the world of computers is measured in bytes. Bits and bytes aren’t the same thing. But to put it in context: to send a photo that’s 2.2 megabytes (MB) when stored on your hard disk, it’ll take about 3 minutes for the transfer if you have a 5 Mbps Internet connection.
If we were to get technical, we’d quibble with the reliability of those numbers and whether they’re useful for more than a general comparison. So would your helpful nephew. If you later decide to explore the underlying technology, you’ll learn the reasons for this. But for now, simply assume that 6 Mpbs is faster than 5 Mpbs, as a useful oversimplification.
Obviously, most people prefer faster speed to slower. Many providers price their services accordingly.
Realistically, if you’ve been using a dial-up modem to access the Internet, it will all seem blazingly fast. If you’re planning to use the Internet for relatively ordinary purposes, such as e-mail, Web browsing, and instant messaging, then your provider’s “basic” speed is probably enough whether you choose cable or DSL. Speed matters a lot more if you expect to work with large files, such as movies, photos, music, games, and any other application that caused the computer salesperson to say, “Hmm, you probably should get a bigger hard disk.”
Q: Why do Internet providers list upload and download speeds separately? Should I care? One aspect of connection speed that is important is the difference between upload speed and download speed. Download speed measures how quickly the information on the Internet is sent to you, such as the email you receive or the Web pages that appear in your browser. Upload speed indicates how fast the information is sent from your computer to…well, to anywhere else.
In many cases, especially with cable service, the upload speed is much slower than the download speed. That sounds like a bad thing, but in most cases the upload speed isn’t a key issue. Think about how you got to this article. You probably typed something into a browser window (such as “compare dsl and cable service” in a search engine). You clicked on a couple of links. And that was about it. A few words of typing, and the clicks. Those didn’t need to speed up the line at warp speeds; you could manage it even if your typing skills are generously described as “hunt and peck.”
But the computer where this page is stored is sending you several pages of information — so you want the download speed to be fast. (This is a very simple example. Your “just a few clicks” could also have shown you a movie, which would have a lot of data to download!)
In some circumstances, the upload speed matters. But for ordinary home use it’s fine for the upload speed to be much lower than the download speed.
Q: How do cable modems work? A cable modem connects a single computer to the Internet using the cable TV network. If you have cable TV service in your neighborhood, you can almost certainly get cable service.
Specifically, the cable modem is a black box with blinking lights. It connects to the computer with a network cable, which may be Ethernet, USB, or some other kind of plug. No matter how old your computer is, it almost certainly has one of these plug-connections available.
Q: Do you need cable television to use a cable modem? No. You do need to be in an area to which the cable company provides service, and the cable company needs to physically get the cable to your location if it hasn’t done so already.
Also, expect a sales pitch on choosing cable TV service to accompany your new Internet access, perhaps with price encouragement (“do you want fries with that?”), but technically speaking there’s no need for you to sign up for HBO just so you can send e-mail faster.
Q: How does DSL work? DSL (digital subscriber line) connects a computer to the Internet using the same wires as a regular telephone line. Although it sounds like it will make your phone line “busy,” DSL doesn’t work that way; the phone service isn’t affected by the Internet connection. In most cases in the U.S., the DSL connection is a phone socket, and your existing house wiring carries both phone and data. It, too, may use a black (or white) box with blinking lights.
Q: Why is distance an issue with DSL? And distance to what? A key difference with DSL is that its speed relies on the distance to the “central office” or CO. That term sounds as though there are office workers slaving away doing paperwork, but in most cases the CO is a large building with a huge number of wires — no humans at all. The farther your computer is from the CO, the worse the signal quality, and thus the connection speed is decreased.
Don’t take out a tape measure. When the phone company judges your distance to the CO, they measure the wires installed between your home and their equipment, which is probably not a straight line.
While it isn’t a technically accurate analogy, imagine shouting to someone across a field. At some point, the other person won’t be able to hear you. If you’re within 5,000 feet of the CO, your Internet access speed will be faster than if you’re 15,000 feet away. And if you’re 22,000 feet from the CO, you probably can’t even get DSL service because the provider knows you’d never be happy with the performance.
There are different kinds of DSL service, and you may be able to use one of them even if you’re (relatively speaking) far from the CO; but you won’t be able to expect top connection speeds.
Q: Why are there different flavors of DSL? Do they matter? When people talk about DSL, they generally mean ADSL (Asymmetric DSL). It would be easy to get extremely technical here, but the simplified explanation is that ADSL is intended primarily for low use, with download speeds many times faster than upload speeds. That’s fine for most residential purposes.
In contrast, the upload speeds on Symmetric DSL (SDSL) are almost the same as its download speeds. That matters if you plan to do a lot of online gaming or to run any kind of Internet server (the latter is unlikely for home use, but the former is quite common if you have children at home). However, SDSL is more expensive than ADSL, and you usually have to be fairly close to the CO to be able to get the service.
There are a few other kinds of DSL connections. You’re unlikely to choose these, but you may want to be familiar with the names when you see them on price lists. Very high bit-rate DSL (VDSL) and Rate-adaptive DSL (RADSL) are of use primarily for businesses. IDSL is based on ISDN technology, and can connect from as far away as 50,000 feet with the currently used versions; it’s a lot more expensive because it’s based on another telecom technology.
Q: I’ve been told that one is slower than the other…? It depends on whom you talk to. Cable service detractors point out that you are sharing the connection with all the other Internet users in your neighborhood. Thus, one person playing an interactive game can hog all the resources and reduce your connection speed, particularly during peak hours (such as when the neighbor’s kid ought to be doing her homework).
Those descriptions make it seem as though you’re on a telephone party line (if you’re old enough to remember those…), with a neighbor listening in on your conversations. It’s not like that; the situation is much closer to waiting in a long line at the bank at lunchtime. They never seem to have enough tellers to deal with the sudden up-tick in customer demand.
On the other hand, the people who criticize DSL point out that residential DSL is also over-subscribed, and the Internet access speed suffers — another example of the missing bank tellers.
So the summary is: yes, one is slower than the other. But which is faster will depend on the area in which you live, and which service is more popular!
Q: What if I have more than one computer? This essay was written assuming that you have only one computer at home. But many families (and many individuals) use more than one computer, in which case you want them all to use the same fast Internet connection. To do so, you’ll need to set up a small home network, in which one computer (connected directly to the cable modem or DSL connection) acts as a referee for all the other computers in the house.
The setup for such a network is outside the scope of this article, but be reassured that it isn’t difficult to get one working. You should be able to find a local computer consultant (or brilliant nephew) to assist you if you don’t want to take on the challenge yourself. In addition, some providers will sell you networking setup at an additional price.
Q: Does it matter if I’m running a business, versus connecting to the Internet from home? Maybe. It depends on the nature of the software you’re running at your business, and how many people need to use the Internet at the same time.
For most small businesses, with only a few employees, there won’t be any difference between residential and business service, without regard to DSL or cable. A business in which several (say, ten or more) employees are concurrently using the Internet should probably examine the business services branch of the DSL or cable provider. These cost more than the residential versions but they also give you additional services, such as more e-mail accounts.
Another reason you’d need business-class DSL or cable services, even in a solo home office, is if you choose to run certain kinds of Internet software, such as an e-mail server or a Web server. Those applications require something called a “dedicated IP address,” which we’ll get to in a moment. Should you plan to add Internet servers to your business, you’ll probably need professional help. It’s more likely that you’ll arrange with another company to manage your Web site and e-mail, which makes the DSL versus cable issue much simpler.
Q: What’s all this stuff about “IP addresses” and why should I care? Under most circumstances, you won’t need to know what an IP address is. However, you’re sure to come across discussions about them while you’re shopping for broadband services, so you might as well have a basic understanding of the term.
Most simply: think of the IP address as the “telephone number” of your computer. Just as you need to know his phone number to call your nephew for help, the computers with which your computer interacts online need an address to reach it, at least for the duration of the current conversation.
With both DSL and cable connections, the standard type of IP address is called a “dynamic IP.” That is, the Internet service provider can change the IP address of your computer at any time. That’s never a problem when, so to speak, your computer is the one calling out. Just as it doesn’t matter to your nephew from what phone number you called him, the only thing you both care about is that you dialed the right number so he could pick up the phone.
However, Internet servers (such as the computers that manage and send out e-mail or host all the pretty Web pages you look at) must have an unchanging address, called a “static IP address.” It’s one option when you look at business-class DSL or cable modem service, and it does cost more.
Q: Do I need to buy extra hardware? Usually, you don’t need to buy anything more than the cable or DSL provider includes with the service. If your computer is an older one, you may need to buy a network card (the techie nephew might call this a “NIC”), which should cost about . If you decide to network together your home computers you’ll probably buy additional equipment. But in general, you don’t need to spend additional money.
Q: What about security? This is a bit of a tangent from DSL-versus-cable, but it’s an important item to mention for anyone who is considering moving from a dial-up connection to an always-on Internet.
In most ways, a faster Internet connection will be a wonderful experience. It will change the way you work online and give you more freedom to explore the world.
But there’s one disadvantage that someone needs to warn you about. You’ve probably heard about computer viruses, spyware, spambots, and other “malware” (malicious software). You’ll now be more vulnerable to it. One side effect of your faster connection is that it’s easier for Bad Guys to exploit your computer because the computer is more regularly accessible.
The result is that you’ll need to acquire anti-virus and anti-spyware software, and probably a software firewall — particularly if you use a Windows-based computer. (Other types of computers aren’t immune but they are much less at risk.)
You deserve to get the most out of your services, whether it’s high-speed Internet, phone, cable, or HDTV. Digital Landing is here to help, making it easy to find out everything you need to know about digital services for your home.
