Dell Notebook - Light, Thin and Extremely Portable

January 31st, 2010

A Dell notebook may be quite an acquisition for somebody interested in computers and in need of one that is light and thin, therefore extremely portable. On top of the fact that it is easy to handle, a Dell notebook doesn’t go too deep in your pocket. For instance, the new Dell Mini Inspiron costs less than $500 but but the price moves up with every new feature incorporated. This Dell notebook relies on a TFT display with a specific resolution of 1024×600 pixels. The processor is an Intel Atom with a frequency of 1.6 Ghz. Furthermore, with a Dell notebook you eliminate lots of the bothersome cables necessary for photo and data transfers, as this computer comes with a card reader for very easy use. The two operating systems it can function with are OS Windows XP and Ubuntu Linux.

Another Dell notebook that has widely appealed to customers is the artist edition Inspiron 1525. The looks of this series is totally new and therefore more attractive or stimulating as compared to other notebooks. Not only can you choose the color to represent you and go with whatever piece of outfit you want, but also the pattern or drawing that surely says more about who you are. Dell notebook manufacturers have started cooperating with Mike Ming, a Brooklyn artist, owner of two plants the Sea Sky and Bunch o’ Surfers and who had the idea of bringing a little more sense of energy, playfulness, sophistication and psychedelic dynamics to a mini laptop that has gained more and more appreciation in nowadays’ society. The original Mike Ming design will not wear off in time preserving the quality inlaid design and colors.

All in all, a Dell notebook should be chosen carefully depending on what work you need to do. If the mini laptop is merely for your own free time, then the Inspiron line offers all the features you may actually need. The designs in this category remain the first choice of users who want a computer handy and available regardless of their location. However, these Dell notebook models are not highly performing like the ones in XPS line, but they can be upgraded. As it results from the above lines, the XPS line of Dell notebooks is professionals’ choice as these can really support the different needs of their users.

Forensics - IT

September 2nd, 2009

Forensics is an ever evolving science with a lot of possibilities acquire deeper knowledge about by different forensics training or forensics classes.
The number of crimes involving electronic data is sky-rocketing these days, particularly with the immense preponderance of computers and other digital media in our lives. Thus, only data forensics experts can search computers for electronic evidence, make digital investigations, recover lost data and provide technical expertise. Data forensics is right to use in judicial cases that involve sexual harassment, intellectual property theft, discrimination, breach of contract and so on. Therefore, it was not difficult for data forensics to become a legal necessity in the context of the computers’ ubiquity.

A normal type of computer investigation cannot detect or extract bits of information remained after deletion. Data forensics will normally examine files that are hidden, deleted or even discarded, as well as fragments or file left-overs. Although it often seems impossible to identify the criminal process or to recover data, experts in this fields have more than once been successful at finding the needle in the haystack. What relevance does such evidence have for legal cases? Well, practice has already proved it that even the course of a trial could be changed by the retrieval of deleted e-mail messages for instance.

The challenges that data forensics expert have to face are enormous. The applications do have far-reaching applications, but it takes hours to extract digital evidence and make it stable. Sometimes the necessary information is buried deep in the corporate electronic system, or sometimes, even if it is physically identifiable it is difficult to separate and analyze extensively, off line. This is also the reason why a duplication procedure is used to protect the information during the extraction process. Great caution, strict standards and lots of skills are required for each of these steps and only real pros can succeed.

A data forensics expert should be contacted immediately, once a breach in the security system or a criminal act against electronic media is detected. This will enable the appropriate and cost-limited data collection in the best conditions possible. Besides computers, there are other electronic storage devices that can be the target of criminal activity, and data forensics also deal with hacked USB devices, DVDs or voice mail systems. Even photocopy machines include hard drives and the scanned or copied documents can be afterwards retrieved from them.

Becoming annoyed with my computer

June 5th, 2009

Like most people I have at some points become frustrated with my computer. Until latley though the issue was becoming ridiculous. The PC was going so slow it was painful and it was always crashing. In fact if I were to compare my computer to how it was when I first got it, I would say it was 80% slower. In fact my computer was so slow it reminded me of my old spectrum which I used to leave to load up while I did something else.

 

Anyway having endured the problems with the computer for several months I finally snapped and decided that I was either going to fix the computer or buy a new one. With computer being expensive items I decided to pay serious attention to the concept of fixing the computer. I began, as most people would do, by searching the Internet. Having searched the net and read lots of articles I put together a list of possible soultions. The first and clearly most obvious solution to the problem was to “De-Frag” the computer's hard drive. I did this but it had little effect. The next solution to the slow computer issue was to remove any viruses or spy ware that my be on the computer. I ran a program called AVG anti virus to do this and it did have an effect on the computer with it running a fair bit better afterwards. The computer was still not as good it it once was though so I moved on to the last possible solution which was to scan the computer for registry errors. Having run a free registry check, the registry checker I used identified around about one hundred and twenty errors. It cost me thirty dollars for the software to fix the errors but it worked quickly and made a significant difference to the speed of my computer. I guess the lesson is that if you are prepared to put the time in, repairing your computer you can save a lot of money.

 

Choosing Online Computer Career Training 2009

February 24th, 2009
by Jason Kendall

What might you expect the most superior Microsoft accredited suppliers to provide a trainee in the UK today? Obviously, the most supreme Gold Partner Microsoft accredited programs, presenting a selection of courses to take you into a selection of professions with IT. Perhaps you’d like to talk to industry experts, who can give you some ideas on what sort of job would suit you, and the kind of tasks that are suitable for somebody with your character and ability. Training programs should be put together to match your current skills and aptitude. Consequently, after working out the right IT job for you, your next requirement is the most suitable program that will equip you for the role.

The world of information technology is amongst the most stimulating and innovative industries you could be involved with. Being a member of a team working on breakthroughs in technology is to do your bit in the gigantic changes affecting everyone who lives in the 21st century. We’re only just starting to get a feel for how technology will affect our lives in the future. Computers and the web will massively alter how we regard and interrelate with the rest of the world over the years to come.

The regular IT technician in the UK is likely to receive considerably more money than employees on a par in another industry. Mean average incomes are around the top of national league tables. There is a great nationwide requirement for professionally qualified IT workers. In addition, with the marketplace continuing to expand, it appears this will be the case for the significant future.

It’s indisputable, the computer industry promises marvellous opportunities. But, to investigate fully, what questions do we need to be posing, and what are the sectors we need to investigate?

Many companies focus completely on the certification process, and avoid focusing on the reasons for getting there - getting yourself a new job or career. Always begin with the end in mind - don’t get hung-up on the training vehicle. Imagine training for just one year and then end up doing the job for 20 years. Avoid the mistake of opting for what may seem to be a program of interest to you only to waste your life away with a job you hate!

Stay tuned-in to what it is you’re trying to achieve, and then build your training requirements around that - not the other way round. Keep your eyes on your goals and ensure that you’re training for something that will keep you happy for many years. You’d also need help from an experienced person who can explain the market you think may suit you, and is able to give you ‘A day in the life of’ explanation for each job considered. This really is essential because you need to know if this change is right for you.

Students who consider this area of study often have a very practical outlook on work, and won’t enjoy sitting at a desk in class, and struggling through thick study-volumes. If this is putting you off studying, try the newer style of interactive study, where learning is video-based. We see a huge improvement in memory retention when we use multiple senses - experts have been clear on this for many years.

Study programs now come via DVD-ROM discs, where your computer becomes the centre of your learning. Using video-streaming, you can watch instructors demonstrating how to perform the required skill, followed by your chance to practice - with interactive lab sessions. Always insist on a study material demo’ from the training company. You should ask for expert-led demonstrations, slideshows and interactive labs where you get to practice.

Often, companies will only use purely on-line training; while you can get away with this much of the time, imagine the problems if you lose your internet access or you get a slow connection speed. It’s preferable to have DVD or CD discs that will solve that problem.

One of the most important things to insist on has to be 24×7 round-the-clock support from professional mentors and instructors. Too many companies will only offer a basic 9am till 6pm support period (maybe later on certain days) with very little availability over the weekend. Look for training with proper support available at any time of the day or night (irrespective of whether it’s the wee hours on Sunday morning!) You want access directly to professional tutors, and not access to a call-in service which takes messages - so you’re constantly waiting for a call-back - probably during office hours.

The most successful trainers incorporate three or four individual support centres across multiple time-zones. They use an online interactive interface to provide a seamless experience, no matter what time you login, help is at hand, avoiding all the delays and problems. Never make do with anything less. 24×7 support is the only way to go when it comes to technical training. Perhaps you don’t intend to study during the evenings; often though, we’re working when traditional support if offered.

It’s essential to have authorised exam simulation and preparation programs as part of your course package. Some students can be thrown off course by trying to prepare themselves with questions that aren’t recognised by the authorised examining boards. Sometimes, the question formats and phraseology is unfamiliar and it’s important to prepare yourself for this. A way to build self-confidence is if you test how much you know by doing tests and simulated exams to prepare you for taking the real thing.

Sometimes students assume that the tech college or university system is the way they should go. So why then is commercial certification beginning to overtake it? With a growing demand for specific technological expertise, industry has had to move to specialist courses that the vendors themselves supply - for example companies such as Microsoft, CompTIA, CISCO and Adobe. This usually turns out to involve less time and financial outlay. Essentially, only required knowledge is taught. Actually, it’s not quite as pared down as that, but the principle objective is to cover the precise skills needed (along with a certain amount of crucial background) - without trying to cram in every other area (as academia often does).

Imagine if you were an employer - and your company needed a person with some very particular skills. What’s the simplest way to find the right person: Wade your way through loads of academic qualifications from graduate applicants, asking for course details and which trade skills they have, or choose particular accreditations that perfectly fit your needs, and make your short-list from that. You’ll then be able to concentrate on getting a feel for the person at interview - instead of having to work out if they can do the job.

Be on the lookout that any accreditations you’re working towards will be recognised by employers and are current. The ‘in-house’ certifications provided by many companies are usually worthless. If your certification doesn’t come from a company like Microsoft, CompTIA, Adobe or Cisco, then you’ll probably find it won’t be commercially viable - as it’ll be an unknown commodity.

Ten Ways To Boost Windows XP

February 12th, 2009
by John Jones

Many people are interested in making the most of their hardware. So here are 10 simple tips on how to make your Windows XP computer run faster without having to purchase additional hardware.

1. Defrag Disk to Speed Up Access to Data - One of the factors that slow the performance of the computer is disk fragmentation. Disk fragmentation really can slow down your computer. Just go to accessories and find a dusty fragments are and let that run. It might take all afternoon, but it should speed up your machine. There are also several paid apps available as well.

2. Detect and Repair Disk Errors - Over time, your hard disk develops bad sectors. Bad sectors can severly hurt disk performance. To detect and repair disk errors, Windows has a built-in tool called the Error Checking utility. It will meticulously search the hard disk for bad sectors and system errors and repair them for better performance.

3. Disable Indexing Services - Indexing Services is a little application that uses a lot of CPU. It’s very annoying. It also doesn’t work as well as Google Desktop for searching your files. Disable it fast and speed up your machine.

4. Optimize Display Settings - Windows XP is a looker. But it costs you system resources that are used to display all the visual items and effects. Windows looks fine if you disable most of the settings and leave only a few necessary bells and whistles. Use a simpler theme or turn off some of the destop effects. Another option is to run fewer programs that are graphically intense.

5. Speedup Folder Browsing - You may have noticed that everytime you open My Computer to browse folders that there is a little delay. To fix this and to increase browsing speed, you can disable the “Automatically search for network folders and printers” option. Most of us don’t have network drives and network printers attach your computer. Anyways. So these options are completely useless.

6. Disable Performance Counters - Windows XP has a performance monitor utility which monitors several areas of your PC’s performance. These utilities take up system resources so disabling is a good idea.

7. Optimize Your Pagefile - You can optimize your pagefile. Setting a fixed size to your pagefile saves the operating system from the need to resize the pagefile. Windows XP sizes the page file to about 1.5X the amount of actual physical memory by default. If you have less than 512MB of memory, leave the page file at its default size. If you have more than 1GB of memory, you probably can set the page file at 512MB or 1GB and that is more than enough.

8. Remove Fonts for Speed - Fonts, especially TrueType fonts, use quite a bit of system resources. For optimal performance, trim your fonts down to just those that you need to use on a daily basis and fonts that applications may require. Unless you are a gfx designer, you shouldn’t need 1,000 fonts. That’s just silly.

9. Use a Flash Memory to Boost Performance - To improve performance, you need to install additional RAM memory. It’ll let you boot your OS much quicker and run many applications and access data quicker. On vista you can use a program called ReadyBoost to do this, on XP programs like eBoost can help. unfortunately, while there is some benefit from what I’ve read, this is not going to give you a huge boost in speed or performance. Built-in RAM is usually going to help more, up to about 2GB, after that you see diminishing returns.

10. Perform a Boot Defragment - There’s a simple way to speed up XP startup: make your system do a boot defragment, which will put all the boot files next to one another on your hard disk. When boot files are in close proximity to one another, your system will start faster. On most systems, boot defragment should be enabled by default, if not, enable it.

I hope this article help you improve your computer’s performance. Even just a little. here’s a bonus tip for you if you browse the web or a lot, you should check out Google’s new browser is the fastest browser currently available and could really speed up your Web applications as well.

Tips on How to Maintain Your Computer’s Performance at Its Best

January 21st, 2009
by Addie Jabat

A computer that is 5 years old or more can still perform like brand new if you only know how to take care of it. Well, taking care of a computer is just simple. Just the basic things, use the computer properly, get some softwares for computer maintenance, and run various programs that are needed to be run to ensure computer’s smooth performance.

Specifically, remember to:

* Follow the rule in shutting down computers. Until Windows has shut down, never turn your computer off with the power switch. Doing so will prevent temporary and/or permanent hard drive defects as well as prevent Windows problems.

* Maintain free space of 300 MB in your drive C. If you use Vista or Windows XP then make it 400-600 MB. Be aware that not maintaining enough free space for your drive C will cause the dumping of data to your hard drive that will eventually lead to slow performance.

* Secure Norton Utilities to get access of Cleansweep so you can clean up your drive for good computer performance. There are some other hard drive cleaners out there, so if you don’t like using Cleansweep you are free to go for other options.

* Make use of the Add/Delete tool in the Windows Control Panel to get rid of the programs that are not anymore needed from your drive. This will help boost maximum performance of your computer.

* Get a firewall program in case you have a high speed Internet connection. Doing so will keep your computer away from hijackers. You shouldn’t want somebody else run your computer.

* Have a virus checker in your computer and run it frequently. Viruses can seriously slow down your computer’s performance or worst destroy your hard drive permanently. You can try Norton Antivirus or those free online virus checkers like Housecall by Trend Micro.

* Run the Defragment and Scandisk tools even just once a month. Doing so will keep your hard drive healthy. Be aware that if your hard drive is healthy, your computer will also perform at its best.

* In times like your computer starts to show symptoms for a serious registry trouble like for an instance freezes, hardware malfunctions, slow windows start ups, computer error messages, system32 error messages, and the like, secure a registry cleaner right away. There might be some errors and corrupt files in your registry. These errors and possible corrupt files will seriously compromise your computer’s performance.

Choosing an MCSA Course

December 29th, 2008
by Scott Edwards

The Microsoft MCSA course is an ideal qualification for anyone looking to get into network support. Whether you’re about to join the IT industry or already have experience but need to formalise your skills with certification, the right training exists for you.

Each of these scenarios needs a different solution, so make sure you’re on the right training programme before getting your credit card out. Find an organisation that takes the time to understand you, and what you’re looking to do, and one that has the ability to give you the information you need to make your decision.

A good advisor should have the ability to work out which type of job will suit you best - based on your personality, likes and dislikes in the working environment (and explain why!). They should also be able to give you a good understanding of what the job entails.

Once you’re happy, choose a course to suit your current skill level so you’re not dropped in at the deep end! Only choose recognised training courses that are in demand in industry.

Modern training courses are delivered on a library of discs which comprise of the latest state-of-the-art video tutorials, detailed on-screen demonstrations and interactive environments where you can practice what you’ve just learned. This is the easiest and most natural way to learn - you repeat as often as you like, and not a book in sight.

When studying for an MCSA course you’ll need full support. Unfortunately many colleges only offer ‘office hours’ support - backed up with an out-of-hours message system. They claim this is 24/7 support but you’re unable to communicate with a tutor at the most common times students study i.e. evenings and weekends. So if you are studying alongside a job, be warned.

You’ll appreciate the need for real 24/7 support once you start. When you need assistance, even if it’s at 1am on a Sunday, there should be a team of tutors available to help you there and then, avoiding irksome interruptions that mess up your momentum.

Because of the quality of this training environment, there’s no need to attend classroom based lessons - you’re getting individual attention from the comfort of your own home. This makes your life much easier, with no need to travel away from your home and family.

Another must for any training course of this level is that it includes exam practice software. These are mock-exam tests that let you practice prior to sitting the real thing - They allow you to measure your results to know when you’re ready and get used to the way the questions are asked. Used properly it will ensure you pass first time. Without such a tool it’s unlikely to happen and your fees through re-sitting will mount up.

Look Before you Leap into Free Web Hosting

December 27th, 2008
by Theodore Metagastar

There are many options available to us these days for free web hosting. Before you leap into a free hosting site there are things to consider. Building and promoting a website takes time, and you can lose many good features by choosing the wrong host.

Why do you want a website? Is it for connecting with your friends, and making new friends? Social networking is a big industry these days, with many sites such as Facebook and MySpace. You can easily invite and connect with your people.

Are you looking for good hosting for your photo you might want to check out Flicker, though the social networking sites will serve you as well in displaying many photos.

Many of the free web space hosts give you options such as templates and add on features. What they offer will vary depending on the host.

There is yet another level to free web hosting that many of these free sites do not allow, and that is the display of ads. Sure, you can talk about something you offer, and provide links to other sites, but many have it in their sign up that commercial sites are not allowed. Some do allow Google Adsense, such as the Blogspot site now owned by Google.

One of the disadvantages of a free web space is the name of your website. Though you will have a little creative latitude on a portion of the name, it will always contain your free web space domain name as well. One example of this is http://atravel-adventure.blogspot.com. The host domain is blogspot, with the subdomain atravel-adventure.

Depending on the type of site you want to have, you may have to think about paid hosting. For example, if you want your own domain name, like http://afreewebspace.com, , you will need to find a hosting site and purchase your domain name. Having your own host gives you more control as to the design and features of your site. One options is using a content management system, which we will talk about in the next article in this series.

Check out some of the free web space hosting sites to compare services available. Even if you outgrow your free web space hosting over time you can always link it to a new site, such as your own domain, and flow the traffic you have built to the new location.

One of the advantages of having a free web space is storage of your photo and ideas. Having an offsite storage place for your memories can save a lot of heartache in the event of a computer crash.

Free web space hosting is here to stay. Isnt it time you start your own website?

How To Remove Spyware Threats

December 16th, 2008
by Steve Banton

Most users of the Internet have some form of spyware or adware installed on their system and don’t even know it. People have found ways to profit from spyware, so it is becoming more and more advanced. Using a spyware removal program that is as advanced is required to remove it.

What is spyware, exactly?

They are programs that install themselves on your computer and silently run in the background logging your activities and in many cases sending them to a thrid party. These programs may be market research programs or even keystroke loggers, which may send personal information out over the Internet such as passwords and credit card numbers.

How can it get onto my PC?

It is usually downloaded with other programs that are not perceived to be malicious or through insecure file sharing programs. It can also be downloaded silently just by browsing a webpage.

Is spyware dangerous?

It depends on the spyware program. Some programs can be more malicious than others, but it generally depends on what the third parties who are collecting the information do with it. Spyware generally does not harm the computer - it usually hides as well as it can so that it can continue to collect information.

How can I get it off my computer?

The best way to remove it is to use spyware protection software which can scan your computer for any threats that are present as well as protect it from any future threats.

Chances are there is a lot of spyware on your computer if you have never scanned your computer before and use the Internet a lot. Spyware is everywhere and even the most cautious users find that it can find a way onto their computers.
