What To Consider When Buying A Computer

What To Consider When Buying A Computer

Will service be on site? Does the vendor offer a collection service if there is a problem? If not, is the vendor close enough for me take the computer back or will I have to pay to send it? Is it worth paying a little more to a local dealer with immediate access to backup services if/when something goes wrong?

Will the vendor sell me something more expensive or complicated than I need?

Talk to them and get a quote from more than one vendor. A reputable dealer will sell you what you want/need, not what they want to sell you.

Is an installation service offered? Helpful if you are a mature beginner and have never set up a computer before. (Of course if you happen to live near Ledbury, we will set it up for you!)

Do I need a laptop or a PC?

Generally PCs (personal computers) are cheaper. Laptops take up less space and can be stored in a cupboard. A PC will always be on show but set up ready to use. A laptop can do EVERYTHING a PC can do (this is a question we are often asked.)

BEWARE of 'bundled' (free, included) printers.

Often the ones included are the ones they couldn't sell any other way because they are the most expensive to run. Check the cost of replacing the ink cartridges BEFORE accepting the printer. It might turn out to be CHEAPER to buy a separate printer which uses cheaper, compatible cartridges.

How To Fix A Slow Computer

Do you want to learn how to fix a slow computer? Most likely you are a computer user, but have no idea about why your computer starts to slow down over time. Having experienced a slow computer myself, I was finally able to clean up my slow computer and make it run like brand new again.

What I Did To Fix My Slow Computer

To make your computer run faster again, you will need to repair your registry files. They are the files in your computer registry that give the software and hardware the instructions to run properly. A computer registry filled with errors will cause the computer to slow down, because the applications get stuck while running. Another result of a bad registry is the frequent freezing of the computer.

How To Fix Your Computer Registry

The computer registry is a component of the computer that is not regularly talked about, yet it is one of the most important. Most people have no idea about a computer registry, even after years of using their own PC.

Fixing your computer registry requires you to download a good registry cleaner. Try not to fix your registry by yourself, because any mistakes made may be fatal to the system. The registry cleaner I used managed to detect all the errors in my computer registry, and proceeded to clean up all of them. The whole process took about 10 minutes to complete. To download the top registry cleaner on the internet, visit my website link below to learn more about the best 5 registry cleaners.

Computer Security: The Essential Components For A Safe Computer

Today, computers are almost as common as the telephone in the home. Computers themselves do not pose a threat to security. When connected to networks and chaos that is the World Wide Web, computers have become tools that identity thieves and hackers use to extrapolate this chaos. In order to establish computer security, software companies have set up mechanisms to prevent risks and the chances of viruses, spyware, spam and pop-ups.

The first of these is a new anti-virus software. There are two large companies that offer this program: McAfee and Norton. These programs work to scan the files on your computer and view them for the attributes that are in or virus are often linked to viruses. These traits or attributes are often called virus definitions and need to be downloaded on a fairly regular basis. In addition to the files on your computer files on CDs, floppy disks and e-mails can and should be filed. There is no doubt about it: anti-virus software is essential to computer security.


Next on the list is spyware scanning software. Spyware occurs when certain sites run programs in the back ground of your computer while glean some information. Information can be as mild as monitoring such websites you look at the acquisition of real passwords. Whatever type of spyware, it can slow your computer to a crawl and should be removed from your computer. Two options are popular software Spy Sweeper and Ad ware.

Lastly, but certainly not least are pop-up blockers and extent of filters. Not only pop-ups and spam annoying, but they often contain spyware scanning software described above. In addition, they can slow down your computer incredibly low. And when you are angry at your computer, your computer is not safe!

In addition to these software components, there are still a few tricks that you can use to keep your computer and your information secure. Password sure what you can and when you create passwords, do not make them easy. Do not use your name, your birthday or your social security number. And, if you are on a wireless network unsecured, do not check your bank statements. These networks allow several people at once. Remember, the pirates are intelligent. You must be intelligent!

Two Dads: One Computer-Maniac, The Other Computer-Phobic

I have two Dads. That sounds strange doesn’t it? One is my genetic father, and the other is my geneticist father. The genetic Dad I’ve only ever lived with for one year when I was an infant, while the geneticist Dad is what you would call a step-father, but I’ve lived in close proximity with him for more than 20 years. I feel close to them both. I connect differently with each of them but on a pretty much equal level. The reason I’m sharing my personal information with you is because I’ve just had a realisation about my fathers in relation to the area that I work in: computers and the Internet. It’s really quite interesting.

One father is a computer maniac. Whenever a new technology, software, gadget, or website emerges he is one of the first to grab it up and evaluate it. My other father has an old piece-of-crap box that looks something like a computer, with a tediously slow dial-up connection to the World Wide Web. Compared to the wireless, broadband Mac personal computer and mobile-connected Mac laptop of the enthusiast, they couldn’t be from further parts of the galaxy.




Then there’s me. I could be construed as being a walking paradox, an enigma, or just plainly twisted when it comes to my relationship with the computer and Internet sphere of life. Nature/nurture, genetic/environmental…For whatever strange reason, I have turned out to be a combination of the two papas. I work as a creative writer for an Internet web-hosting company. I love the ideas and valuable functions and tools that the Internet has brought to humanity (or was it humanity that brought it to the Internet?). However, I have issues and challenges when it comes to using these awe-inspiring machines.

Currently I am away from home in a different city visiting my girlfriend. At home (I am currently living with my parents-Mother and geneticist, as I’m going to live overseas soon) all I have to do to get on the Internet is open up my laptop and I’m on-line. If I’m at work, I go to my PC and all of my settings are stored and ready for me to use. While in a new place, things haven’t been running as smoothly as I would’ve liked. The answers are probably simple and easy to do, but this is one of the kinds of challenges that cause me to stumble. Although I am deeply interested and have a true faith in this new technology, I am a real novice when it comes to getting things done on someone else’s computer.

I brought my laptop with me. My girlfriend only has a dial-up connection which she uses with her laptop. I could use hers’ but she’s Chinese so a lot of what comes up on the screen is illegible to me. I don’t know how to change her language configuration. I’m used to doing it quite easily on my Mac, but her computer is a PC and I’m not as practiced in this other format. That’s one of my problems. I only have so much patience when it comes to working these technological issues out; it could be a trait passed on by my ice-age father (No judgement is being laid here. He just doesn’t feel that he can work new technologies out. He’s had a digital telephone answering machine for two years which he still hasn’t set up. He feels bad about it but his manual one does the job, so he sticks with it.). I’m also a little afraid to hook my laptop up to her dial-up line as I know from experience that I’ll have to change some settings of which I am not confident about doing.

So the next answer was to go to her university where she said people use their laptops wirelessly in the library. That sounded cool so I went in and tried it out. I even tried changing the settings to get it to work (It took courage.) but I couldn’t get it to work. I was weary about asking for help because I wasn’t really a student at that particular learning establishment. Instead, I’ve been using the library’s computers. This is OK, but since I can’t walk away with the files I create (I borrowed my girlfriend’s thumb-drive but an experience from the past of not being able to transfer information from PC to Mac deters me from using it-again, an irrational fear. I know it, and I will give it a try this week. I’ve resorted to saving my files in my email account as attachments. It’s not conventional, but it works.

Another issue I’ve had is getting onto my messenger service. The university computers don’t have it on their desktop, and when I tried to download an on-line version I was told that I didn’t have the authority to do so. I went to an Internet café, and I could do work there (I’m working on the road) but I feel kind of silly paying to get paid. It was cool there though as they had messenger with voice and video and I was able to have a conversation with my brother who is travelling around India. He could see my sister and me, but we couldn’t see him as he said the Indian computer devices (webcams, headsets) in that town were looking a little bit crappy in design and also looked worse for wear. It was heaps of fun making funny faces knowing that he would be seeing us. I think he’s getting lonely as he’s only 19 years old and has been away from home for over 7 months.

As you can see I’ve inherited beliefs about computer from both of my Dads. I find things more difficult than most, I believe, but I’m not going to give up doing my best to get the things done that I feel are necessary. Over time I hope to get over these little obstacles and hurdles and become proficient in all of the cool aspects of this new realm of human endeavour. I also have faith that the technicians and engineers are probably working hard to make things simple for the rest of us.

Whatever happens, I’m going to stick with it, and when I go to see my genetic father next I’m going to do my best to inspire him to buy a new computer with a Broadband connection. Then all I have to do is show him a few of the amazing things that this human created Internet tool can do. One of the aspects of the Web that affects me most profoundly is the simple fact that if you think of anything at all in the known Universe, you can then look it up on your search engine like Google and in the time it takes to blink your eye, immediately start to learn. It sure beats catching the train to the library, looking up a book in the card catalogue, searching for it, then finding out that someone else has borrowed it and is late bringing it back.

The 10 Most Misunderstood Terms In IT

Here are the ten terms that we believe are currently the "most misunderstood" by those who work in information technology. The list is arranged in alphabetical order. We also list a number of terms suggested by our readers that don't quite make the "top 10."
We also list a second list of 10 most misunderstood terms, based on an informal survey of our fellow editors here at Whatis.com and TechTarget.

1) acronym
An acronym is not any abbreviation, just one that forms a "sayable" word. Apart from that confusion, acronyms and other abbreviations cause confusion any time a reader is likely not to know what the spelled-out version is. One Whatis reader said he was especially confused by "acronyms within acronyms" and cited the example of SAX (Simple API for XML).

2) ASPActive
Server Page or application service provider (ASP) - which is it? These are both frequently-used abbreviations in many development shops.


3) ATM
Automatic teller machine - or asynchronous transfer mode? IT people who work at banks sometimes use both kinds of ATM.

4) bandwidth
Does bandwidth mean "capacity or speed in general"? Or does it have a more technical meaning of how wide a broadcast band or other data channel is? Is it OK if it means both? (No one mentioned channel as confusing but it has at least six meanings.)

5) JavaScript
JavaScript is not the same as Java and some people tend to think it is.

6) kilobit
Is a kilobit 1,000 bits or 1,024 bits? Whatis.com says it's 1,000 bits but no one is very comfortable with their position. Since "kilo" has a power-of-ten origin, a standards group has invented a new prefix kibi to represent something that is a unit of (decimal) 1,024 or (binary) two to the 10th power.

7) NET
NET is Microsoft's term for using XML to define and share data across the Internet so that many application services can now be performed remotely. But the set of tools related to this idea keeps evolving and Microsoft somewhat understandably keeps redefining the details.

8) platform
Is a platform hardware (a particular processor and its instruction set) or software that will run on it (the operating system) - or is it both? Or is it just "whatever products are needed to run something on"? Although many readers understand the term in context (or may not care to make the distinction), this term represents many other such fuzzy terms that seem to come in handy for writers if not for readers.

9) server
Is a server a program - or a computer that is dedicated to a certain purpose? Often it means both at the same time, but sometimes it can be important to know, especially if you've just been asked to install it.

10) Windows
The term "Windows" all by itself is a frequent source of misunderstanding since different versions of Windows (95, 98, 2000, XP, etc.) offer different behaviors and problems.

COMPUTER

A computer is a machine for manipulating data according to a list of instructions.
Computers take numerous physical forms. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers. Today, computers can be made small enough to fit into a wrist watch and be powered from a watch battery. Society has come to recognize personal computers and their portable equivalent, the laptop computer, as icons of the information age; they are what most people think of as "a computer". However, the most common form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to control other devices—for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras,and even children's toys.

The ability to store and execute programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks as long as time and storage capacity are not considerations.
