commonly known as "Apps", are basic programs for everyday use, such as;
• Office suites
• Accounting packages for example spreadsheets
• Graphics software
• Media player
• Enterprise software
The most popular software is Microsoft Office which consists of Office, Spreadsheets and Powerpoint presentations, emails and more.
When you purchase a computer most of these basic applications are already installed onto the computer and for most is enough to suit your needs. However some may need specific programs to do specialized jobs, this is more the case with companies or organizations that would need to have software specially designed for what their company requires.
You can create your own software and you don't have to be an IT genius to be able to do this, there are lots of websites that will help you start. You generally have to pay for this, but there is plenty of free advice. Once you have decided exactly what you need, then you can start your project.
Some websites advertise that you can "create your own website in 30 minutes or your money back" I would suggest reading some reviews of others that may have used this before purchasing.
If you would rather not create your own software or simply haven't got the time, then leave it to the experts. There are plenty of freelance programmers out there but make sure you get some references first, as these can be extremely expensive and you need to be 100 per cent sure that they are capable of creating the program you need.
