International Conference on Computer Systems and Technologies - CompSysTech’2004 - IV.28-2 - From the other side the m-Learning is part of e-Learning and therefore - part of d- Learning (fig.1). In the literature there are different definitions for m-Learning. Some of them consider it as only wireless or Internet based. We think that definition of m-Learning must include the ability to learn everywhere at every time without permanent physical connection to cable networks. This can be achieved by the use of mobile and portable devices such as PDA, cell phones, portable computers and Tablet PC. They must have the ability to connect to other computer devices, to present educational information and to realise bilateral information exchange between the students and the teacher. We can consider about the potentiality of the mobile learning by following statistical information concerning the number and the growth of cell phones, PDA, smart phones and users of mobile communications: • more than 50% working places in USA are mobile ; • until this moment all over the world are sold more than 500 mil. cell phones with web abilities ; • the number of sold cell phones in Europe has growth of 25% for the first quarter of 2004 year ; • the number of sold PDA and smart phones has growth more than 200% for the last year ; • every quarter the number of companies developing software for mobile devices increases by 1000 ; • up to 2005 the number of sold multifunctional mobile devices (PDA and smart phones) will exceed the number of sold personal computers ; • up to 2010 over 1 mlrd users will use wireless Internet ; • up to 2010 there will be more than 1,8 mlrd users of the mobile communications . The realise of mobile learning is impossible without use of the mobile devices. They vary significantly in their abilities, sizes and prices. The common ability which united them is their mobility and possibility to make wireless connections. The main types of mobile devices used in the education process are: • NoteBook computers . From one hand they have such abilities as desktop personal computer; from the other hand they have small sizes and support wireless communications. Their prices are still high. • Tablet PC . These are one of the newest mobile devices. They also have full range of abilities as personal computers. Some of them haven't keyboard but have software to recognise handwritten text. It is relatively expensive. • Personal Digital Assistant (PDA) . They have small sizes and significant processor power. New models support more than 65000 colors, recognise handwritten text and can play different types of multimedia files. The main operating systems used are Palm and Microsoft Pocket PC. • Cellular phones . The low class devices mainly can be used for voice communication and sending and receiving of text messages (SMS). Some of their disadvantages are low memory capacity and low data transfer rate. The cellular phones from the higher class can be used to Internet access via WAP or GPRS technologies. They also can be used to send and receive the multimedia messages (MMS). Their prices continuously decrease. • Smart Phones . They are hybrid devices which combine the abilities of cellular phones and PDA. They have smaller sizes than PDA and bigger than cellular phones. Typically they haven't full sized keyboard and can recognise handwritten text. They use Symbian, Windows Mobile or other operating system. As they have Internet browsers they have potentiality to be successfully used in the mobile multimedia education.
