System requirements for implementing and using Microsoft Office SharePoint are as follows:
1. Windows XP: 500 MHz processor (I would recommend 1GHz for proper functioning) and 256 MB RAM (512 MB recommended);
2. Windows Vista: 1GHz processor and 1GB of RAM (I recommended 2GB RAM for proper functioning);
3. Windows 7: 1GHz processor and 1GB RAM (32 Bit) and 2GB RAM (64 Bit). I recommend 2GB for 32 bit as well - to access proper functionality
Proper functionality means faster access to the files stored on the cloud and for real time collaboration.
Price: Before you can use Microsoft Office SharePoint, you need to know that the service comes at a cost. You can use the SharePoint 2010 (latest edition) services free for 30 days and later, if you wish to continue, you will have to pay $5.25 per team member. The fee is valid for a month. Microsoft is also offering a bundle package wherein you can integrate SharePoint with Business Productivity Online Standard Suite (BPOS). If you use the bundled package, the cost goes up to $10 per user per month.
Among the standard features are the ability to upload documents, share them with one or more people in your team, real time collaboration on the documents, and backup facilities. Other benefits include easy inclusion of more members, file encryption (SSL based), antivirus and antispyware guard, etc. This makes your files safer as if they were stored locally while letting your employees or team members access the files you wish to share with them.
SharePoint 2010 also offers several templates and wizards that claim to enhance your experience by offering ease of streamlining different business processes, backing up documents; adding and removing users; WYSISYG features for real time collaboration, and more.
