Downloading Computer Software Off The Net

June 11th, 2011 by Owen Jones

Everybody likes a freebie and that goes for users of computers as well. Getting hold of these free programs normally means copying them from a disk given away with a computer magazine or downloading computer software off the Net. Just what kind of computer software you would like is up to you naturally but you can acquire working versions of most types of software from the Internet, if you look about hard enough.

Most surfers who want to download free computer software from the Net are looking for utilities – utilities such as anti-virus software, anti-spyware utilities, firewalls, back-up programs and word processing utilities.

You can find several thousands of programs like these to download from the Internet by typing ‘free software’ into Google or by going to download sites like download.com, tucows.com and majorgeeks.com, but there are dozens more of them as well.

These free software downloads come in a couple of different forms. These are: freeware, shareware, time-limited usage and limited functionality programs. Freeware is literally free; the writer has put the software into the public domain for anyone to use free of charge.

Shareware is comparable, but you are expected to make a contribution if you like the software or use it regularly. Sometimes shareware is time-bombed so that it stops working after a month or a pop-up shows itself each hour after a month and sometimes nothing happens at all or a couple of features will cease to work (like ’save’ or ’send’).

Time-limited usage software is usually a trial. In other words, you can use the full program, but it will switch itself off until you pay after a predetermined length of time. This is quite common with costly software. Some free software comes with limited functionality from day one, but you can use it for as long as you like. The complete version is available on payment.

There is another type of freeware which is an on-going worldwide product. Into this category falls such software as Firefox, OpenOffice, Wordpress and Opera. These are excellent top-grade products and are completely free of charge.

There are also free gaming web sites, although most of the better games are time-bombed for limited functionality or only work in demo mode, which means that you can just watch, you cannot take part. This is extremely annoying. If you spend an hour downloading a game merely to find that it is a demo version, so strive to find out first.

The other foremost category of free software on the Internet is tutorials. You can find a free tutorial for virtually anything that you want to learn. The majority of free tutorials seem to be on aspects of using a computer like programming or editing HTML, but there are also free tutorials on using major-brand software; passing exams; needlework, gardening, and just about anything else too.

If you would like to start downloading computer software from the Internet free of charge, try some of the names I suggested or do a free search on Google.

Working With Computers

June 7th, 2011 by Owen Jones

These days most individuals and their grandmothers are using computers on a daily basis to access the Net and even the so-called computer illiterate operate computers in items that they have not yet realized contain them. We are all working with computers all the time whether we realize it or not.

Equipment at work, the car, the mobile telephone and the ATM all have computers built-in to make them more efficient or indeed to make them operate at all. Everyone ought to strive to take that small leap to learning how to make use of a computer with a keyboard, particularly if they are under fifty.

Not only are we all working with computers, but we are all working with mainframes – the type of computers that NASA uses for its calculations. Where?, you might ask. Well, when you go to the self-service garage and punch in what you want and how you are going to pay for it, the computer on the petrol pump checks its stock to see whether it can supply that amount

Then it tells HQ that it has delivered that amount and that stock levels have to be decreased by that amount; then it checks you credit card details with the banks’ mainframes and then you are free to have your card back and go on your way. And not before. If you do attempt to get away early, it will already have taken a snapshot of your face and probably your car’s registration plate as well.

Do you have a security tag to get into work? That will be an RFID (radio frequency ID) tag, which will be communicating with the company’s mainframe computer to tell it that ‘employee xxx’ has turned up for work and it will almost certainly keep tabs on where you are at every other moment of the day as well.

Some people used to enjoy doing a little automobile maintenance once a week or once a month (OK, lots did not too), but that is now a thing of the past. Before anyone knows what is wrong with a vehicle, they have to plug it in.

If you go to a main dealer, that knowledge will go into the company’s database to help it create a better car next time (or maybe they will use the data to make certain that it breaks down earlier next time – planned obsolescence).

The point here is that if you do not have an inkling of what computers can do or indeed are doing, you will be left behind, standing in disbelief in the past asking yourself what happened to your old life. The easiest way to find out what computers can do is to begin working with computers on a conscious level.

There is just one problem with this piece though and that is that because you are reading it on line, I am talking to someone who is already working with computers. Never mind, I tried.

Computer Programming – A Brief History

June 5th, 2011 by Owen Jones

If a description of a computer is that it is a machine that needs to follow various directions in order to carry out the tasks required of it, then the history of computers can be traced back to Charles Babbage’s ‘analytical engine’ of 1837. The directions that these machines or computers, as we call them, follow are written as lines of programming in a programme (UK) or program (USA).

In fact there were several ‘programmable’ devices before the ‘analytical engine’. The was the Al-Jazari castle clock of 1206, which recounted the times of the year, the seasons, the phases of the moon and much more besides and the sequences could be altered – a kind of early programming.

Another instance was the Jacquard loom of 1801, which permitted intricate patterns to be woven automatically by a loom following instructions in the form of holes punched in a series of cards. This kind of programming, using punched cards, was still being used in computing in the Nineteen Sixties and early Seventies.

If these engines can be known as computers, it is fair to call them ’single purpose computers’. What most people think of as a computer these days is a ‘general purpose’ machine which can be programmed to perform a wide range of tasks from calculating a spreadsheet to displaying a film.

The difficulty with early computers (first quarter of the Twentieth Century) was how to change the programme and how to input the data quickly. Alan Turing took the first important steps in this direction in 1936 with his formalization of the concepts of the algorithm and computation with the Turing Machine. This device supplied a blueprint for the first digital computer.

The creator of the first programmable and therefore multi purpose computer was Konrad Zuse. The Zuse Z3 of 1941 is thought to have been the first programmable fully automatic computer.

The Atasanoff-Berry Computer of 1937 was an early, partially programmable computer and formed the basis of ENIAC (1946). ENIAC was the first general purpose electronic computer.

Two crucial concepts were introduced by John von Neuman in 1945. These concepts fundamentally influenced the writing of programming languages. The first was the ’shared program method’, which dictated that programs should not be hard-wired into the machine making it multi-functional and the second was the concept of the ‘conditional code transfer’ or subroutine, which could be called from any juncture in the program to carry out a function.

Short Code Language came out in 1949 which required programmers to code in binary and Grace Hopper brought out the A-0 compiler in 1951 which hugely speeded up the process of composing code.

FORTRAN was developed for scientific use in 1957 and COBOL in 1959 for office use. LISP is a language that was designed to handle lists in 1958 and is still being used for this reason today. 1958 also saw the release of ALGOL, which was the launch pad from where Pascal, C, C++ and Java emerged. PERL came along in 1987, Java in 1994.

Microsoft is having a great deal of success with its Visual Basic, which makes use of widgets, but who knows what other languages will be invented in the future and what we will be able to do with them?

What Does A Gaming Computer Require?

May 17th, 2011 by Owen Jones

In order for any article of equipment to function it needs to have certain requirements met. For example, most pieces of equipment require electricity, but there are other, more delicate devices that have more specific requirements. Computer programs are a good example of these. All computer programs require a minimum amount of memory and a certain minimum speed processor to run in.

Computer games are just computer programs, albeit very specialized ones and they have very precise requirements as well. Computer games generally need speed, which just means lots of processing power to read the game/program itself and read the directions from peripherals such as the gaming console.

Therefore, in order to play the faster games, you really require a high spec machine – a much faster machine than you need to run an office and you can browse the Net on a computer that is ten years old.

Another factor in the gaming industry is that the games designers all use the latest and greatest apparatus on the market in order create and test their concepts. Therefore, the end user will have to use comparable equipment in order to get the most from their games.

The minimum needs for playing a game are normally written on the box. Pay attention to the minimum speed of processor; minimum graphics card; minimum RAM; minimum monitor resolution.

The CPU or processor’s speed is normally the stumbling block for gamers. A computer is soon out of date. You can usually upgrade the processor for two or three years, but after that you might require a new motherboard or even a new computer. Units of speed are measured in MHz and GHz (1,000 MHz is equal to 1 GHz). An office computer will happily run most office programs at 2 GHz – 2.5GHz, but you will require 3+ GHz to run most games.

RAM is also terribly critical for games because this is the region within a computer that holds the information that has to get processed most frequently or simply next. Everything else gets written to disk even if it is only for a few seconds. Therefore, the larger the RAM, the less saving to and reading from disk, which takes comparatively a lot more time. Office machines are happy with 2 GB, games machines may need 3-4 GB. Four or five years ago, most people were glad with 500 MB or even 1,000 MB (or 1 GB).

Video RAM (VRAM) used to get borrowed from RAM, which was a bit of a con, actually. Nowadays, high-spec machines have their own VRAM. Get as much as you can, but minimum 500-1,000 MB. VRAM is used by the video card to control the graphics.

Hard Disk capacity used to be a worry but rarely is nowadays. Games are usually loaded from a CD drive or a flash card, but you need a minimum amount of free HD space to write back and fore to (see RAM above). One note here though, if you are buying a new HD or CD drive, go for the fastest you can afford, but most of them are decent enough nowadays. The same with monitors.

Safety Tools For The Internet Users In Your Family

May 16th, 2011 by Owen Jones

Do you want to make sure that people, especially children, in your family are protected whilst they are surfing the Net? If you regard this as one of your responsibilities, then there are a couple of steps that you ought to think about taking.

The problem for young kids surfing is the danger of meeting, or worse still trusting, a bad person. Insults and email bullying are bad enough, but there is much worse that can take place. Therefore, you ought to educate the children in your care about the dangers of the Internet. It is simple to get these dangers out of proportion. They are very rare occurrences in fact, but they do happen despite all that.

There are safety measures that each surfer should take, no matter what age the folks concerned are. The sickos who prey on users of the Net are known as predators by the majority of surfers.

Besides common sense, there are also Internet safety tools that you can make use of to keep your friends and family safe. These tools can be nebulous, as in software, or material, as in hardware.

The first line of defence should be provided before the signal gets into your house. In other words, your Internet Service Provider ought to be jamming known junk and problem emails from arriving at your inbox. If they are not providing this very basic degree of service, then enquire of them why they do not or swap your ISP.

You should never see any ads about Viagra, Cialis, penis or breast enlargement unless you type the query into a search engine. Those days have gone and good riddance.

The next degree of security should be your firewall. If you are using a router, then there will usually be a firewall built into it. If there is not, do not buy it. However, there should be a firewall built into your browser. MS Windows XP and Windows 7 have efficient firewalls, but you can also purchase one.

The third degree is that of parental control switches. However, children learn how to turn these off. Windows has such controls or you can purchase even stronger controls. If you remain with Windows, check your kids’ computer settings at least each and every week when they are at school.

Next, you can block web sites and email addresses one by one. This is accomplished by ‘black listing’ web sites. This is also to be found in the communication software like Outlook, Outlook Express and Explorer, but do not be complacent, kids know how to reverse these blocks as well.

You can also install a ‘Keyword Tracker’. this unit of software will tell you, upon request, which are the main keywords used on that computer. This can be a real eye-opener and can be a very effective manner of knowing what your computer is being used for.

However, maybe the safest method of regulating what your kids are using the Internet for is to have the computer situated in your living room. You might think that it is a shame that it has to come to that, but, hey!, better safe than sorry, or not?

Is It OK To Download Computer Software From The Internet?

May 13th, 2011 by Owen Jones

Do you ever wonder whether it is safe to download items off the Net? I know that I am asked that question several times a month. The fact is, that it depends, like most solutions. It depends on two basic factors: how decent your defences are and where you are downloading from.

You may be thinking: well, if my defences are good, why would it be a problem where I download from and that is a decent question, but so is: what do you think of as decent protection?

If your idea of good protection is a free version of Avira, then you are going to have trouble. One day or another you will have problems, guaranteed. I can say that with my hand on my heart, because they have a paid version too. If the free version is as good as the paid version, why do people pay?

Because they are stupid? I do not think so. By the way, I am not having a go at Avira! They give away a marvelous product and as long as you are cautious, it might be all you need. Avira and all the other decent anti-virus software suites require a little help to keep you secure.

For instance, they will require you to run a firewall at the same time and use an anti-spyware program on a frequent basis. They will also require you to not put yourself at the greatest danger either by visiting a few forms of sites and not opening attachments from people you do not trust.

If you run the free versions of these av software programs, you will notice that some features like the firewall or and the email attachment scanner have been disabled. This is how you will pick up viruses. Another manner that you lay yourself open to problems is by downloading free utilities. These fragments of software almost always include tracking routines.

The software will do its job, but it will install a tracking cookie on your computer which will phone home every day to its boss and tell them where you have been surfing, so that they can spam you with similar things.

Porn sites are another decent instance of dangerous web sites. You receive ‘free porn’, but they receive your IP address and possibly your email address too, which means that they are able to either spam you themselves or and sell your email address on so that half the world can spam you.

So, free av software is OK, but you have to help it. On the other hand paid software from a dependable firm like Norton, Kaspersky and Nod, to name but a few, should take care of you without you having to do anything but pay and install and permit automatic updates. You can expect that from these businesses and they can deliver that degree of protection for $50-60 a year and then you can download anything you like.

The Net is very much a case of ‘you pays your money and you takes your choice’ and ‘free’ is definitely not always the best option.

Choosing Registry Cleaners and Repair Programs

May 4th, 2011 by James Spacey

You may need to repair your computer’s registry if it’s been running a bit rough lately. You should not try this manually. Thankfully, there are a lot of different programs and downloads out there that you can use to clean and repair your computer’s registry. This should help you get your computer running smoothly again. Figuring out which program or download you need can be a challenge. How can you determine which one is best? Read on for helpful hints.

All is not safe on the net because you can get tricked into downloading registry software that is not real, and it’s just a malware plant that puts trojans or viruses on your computer. Is there anything that can be done about that? Is there any way of having a clue about these scam businesses? Do continue reading this article, and in it we discuss these topics and more for making a winning choice for a registry cleaner.

A program that hasn’t changed even an iota in months or years is not worth your time. You never now about it, or why it happens; and you don’t want to fool around with the health of your computer. This is all about compatibility, and that can be a significant issue depending on the specifics. Regular updates also show that the creators of the programs are keeping up with the latest in technology and computer issues.

It is imperative that any cleaner and registry program you download has backup capabilities. You usually won’t have trouble finding a cleaner that will perform an autoscan of your registry, but still, make sure the one you get does that. There are some programs out there that specialize in scanning only parts of your computer or its registry. You really do not want that kind of cleaner program. You can easily find programs that are super easy to use, and they will do the entire registry. You could be asking for problems with programs that are not comprehensive. It really doesn’t make much sense to only take care of part of your registry rather than all of it.

It’s also very tough to assess the quality of customer service with any new company you’re dealing with. Look for evidence that they do offer a way for you to call and talk to real live people. It’s up to you, of course, and that may not matter to you a lot, but it does matter to some people. Companies that scam people will never be able to be contacted, so you have to be as careful as possible. One possible approach is to look for reviews or negative articles or comments on the net.

There’s more than meets the eye when evaluating the best registry cleaner program for your needs and technical abilities. If you want to be a happy consumer when buying software, then you will educate yourself as much as possible and execute good research on your choices. Be sure to choose a program that is the best fit for your needs and preferences. There are a lot of scammers out there who are just looking for the excuse to get into your system and poke around for a while. The best way to go is always perform a search on a program and the company that makes it.

James Spacey is a prolific online wordsmith. As well as writing about registry cleaners he also publishes articles about internal laptop hard drives and a host of other content as diverse as press release software. Visit James by clicking a link today.

USB Memory Sticks – Your Backup Solution

September 28th, 2010 by Seyton B Cyrano

People are resistant to backing up their computers. They know that a hard drive crash can be a disaster, if no data backup is available, but unless doing backups can be made very convenient, they tend to neglect this important precaution. USB memory sticks are such a convenient backup medium that they may alleviate this problem.

Software, such as photo organizers, may sometimes malfunction and destroy files. Users may inadvertently do the same. In the worst case, the computer’s hard drive may fail and wipe out all of the data. Depending on how they are used, computers may contain files with emotional value, such as photographs, or records that may be very hard to reconstruct. If the user can access backup copies of these files, the problem is much less severe.

To backup computer files, one must have a place to put the backup copy. This can be a network destination, or a device that connects to the computer. In most cases a USB memory stick is an ideal backup device for notebook computers.

To the user, USB memory sticks are small, rugged, plastic or metal devices that one can put data into. To the computer, they act like small hard drives that plug into USB ports. They can be as large as 64 billion byes, and will be larger in the future. They usually don’t need to be as large as the main hard drive since one is usually not backing up everything on it.

USB memory sticks are simple to use. In most cases one simply slides the stick into an available USB port; the operating system of the computer will assign a drive letter, e. G., f: to the stick, and it is ready to use. When not in use, the stick should be protected from water, but other than this they are pretty rugged.

Unless there is a lot of data to be backed up, it is simplest to backup all of the data every time. When there is a lot of data, it may be more practical to do an occasional full backup, perhaps once a month. Interim incremental backups, perhaps weekly or daily, that only back up the files that have changed since the last backup, fill in the gaps.

A backup copy of your computer’s key files is somewhat like an insurance policy. In normal day to day life, it has no value. However, if disaster strikes your computer, a USB memory stick with a backup copy of your key data files is very valuable.

To obtain additional help not to mention information which is around memory stick uk plus Credit Card Usb Sticks come along to the website.

Store And Transfer Data Using Flash Drives

September 24th, 2010 by Carver W Szilord

Flash drives offer an inexpensive way to store and transfer data from one computer to another. While these small drives were initially expensive, the price has dropped remarkably to the point that smaller drives are often offered as free gifts by advertisers.

The flash or USB drives easily attach to your computer through any of its USB ports. Power for the drive is supplied through the USB so that batteries are not required. While the drives can easily fit in a pocket or purse, often the housing is large enough that it will block the use of the adjacent USB ports.

While data can be stored and erased on the USB drives many times, you should know that eventually the drive may fail. Thus, USB drives are not the best choice for backing up data. If you plan to use the small drive for such a purpose, you should have more than one copy of critical data.

While called drives, these devices contain no mechanical disk. Data is stored in memory that is installed inside the drive. The data is accessed and stored just like any other disk from the point of view of the computer user. One major difference is the ease of moving data from one machine to another simply by ejecting and removing the disk to plug it into another drive.

Before removing the USB drive from your computer, you should use the option to safely remove hardware. This will ensure that the computer has finished with all the data transfer and protect your drive. If you simply unplug the drive to move it to another computer, you may lose important data and could cause the drive to fail prematurely.

Thumb drives can be used to share photographs or even videos with friends. The large files sometimes are difficult to e-mail, but could be sent by snail mail to other family members. Having the photos in a higher resolution available using the drive makes for better prints of your photographs.

For an inexpensive way to move or store data, consider a flash drive. While the life of the drive is not infinite, it normally makes a reliable way to move data. You should always make sure that you keep a copy of critical data in more than one location, so do not delete the data from your computer until you are sure that it has been stored on another.
