Advancements in Tablet PC Technology
Tablet PCs are increasing in popularity in recent times because of much advancement in tablet technology. Yesteryear’s tablet PCs were not of the same kind as the devices available now. These devices were not having camera and good display. They used to have resistive touch screen which will end up irritating the users after few days of usage. There was no camera, on either side of the tablet. But with the advancement in tablet technology, many new features are being studded in to these devices.
Drastic increase in the popularity and craze for tablet PCs can be attributed for advancements in tablet technology. These devices can be considered as intermediate between mobile phones and laptops. Or they can also be defined as a cross between PDAs and notebook PCs. Earlier, low quality processors and less quantity of RAM used to be provided on these tablets, but with the increase in competition between various brands of tablet PCs in the market, everyone is trying to improvise their devices by providing advanced processors and increased memory. Tablet market has witnessed much growth after the release of iPad from Apple. Soon after that, Samsung has come up with Galaxy tablets running on Android operating system. Handheld nature of these devices can be attributed as one of the major plus points helpful in their success. They are coming with less weight so that users can hold the tablet for longer periods of time. These tablet PCs can be totally considered as a miniature form of laptops except for the fact that keyboard is absent in tablets. Touch screen facility has replaced the need for the presence of keyboards.
With the release of more and more number of brands of tablet PCs in to the market, consumers are really confused to find out the best suitable one for them. New tablets with advanced features and improved technology compared to the existing devices are being released regularly. So, even though consumers buy advanced tablets of that day, they will soon get outdated with the release of newer versions of the same tablet or new brand of tablet. Various features are to be considered while purchasing tablet PCs. Operating system, product manufacturer, Wi-Fi, provision for SIM card, camera, customer care support, support for apps, touch screen facility, interface design, video recording capability and other features are to be checked while buying tablet PC device in the market.

GSM Network technology
GSM and CDMA are the most commonly used mobile technologies in India. GSM Mobiles are becoming more and more popular these days, when compared to its counterpart, and has emerged as the most popular type of telephonic communication technology in India. This kind of technology works based on SIM card. Users have the option of change the mobile phone without changing their mobile number, when they are using this mobile technology.
Best part of GSM technology is that call can be made at good quality along with being secure. It can provide different kinds of add-on services like EDGE, GPRS, etc. Activation of GSM enabled mobiles is different from that of CDMA mobiles. Also, mobile phones which work based on GSM technology consume less power than the mobiles working on earlier technologies. Using roaming packages, it is possible to use the GSM enabled mobile phone while travelling abroad also. There are also options to track the mobile phone, but for this the mobile phone should be using GSM network. It is easy for locating the position of any mobile phone and hence it is very much easy for the intelligence and police for tracking. There is no need for the users to stick on to a particular service provider, when they have GSM based mobile. They can easily switch between various mobile operators for the purpose of availing best services at cheaper costs.
GSM is the abbreviation for Global System for Mobile Communication. This technology is based on the connection between SIM card and the service provider for making or receiving calls, sending texts and connecting to the internet. Wide ranges of mobile phones are offered on GSM technology, so the consumers will have the option of choosing their favorite handset model. This technology is known for dependability and reliability, and hence the list of mobile subscribers using this technology is increasing significantly.
Formal Semantics – Meaning/Definition/Explanation
Study of semantics, of both natural and formal languages, is known as formal semantics. Formal language is the one which can be defined apart from any kind of interpretation of the same. This can be achieved by the designation of set of symbols (known as alphabet) along with set of formation rules (known as formal grammar). Formation rules should be able to determine the string of symbols that have formed as formulas. Up on the addition of transformation rules (known as rules of inference) and upon the acceptance of few sentences as axioms, logical system is established. Transformation rules along with axioms are called as deductive apparatus and deductive system. Interpretation is nothing but an assignment of meaning to the above mentioned symbols along with truth-values to their sentences.
According to theoretical computer science experts, formal semantics is related to rigorous mathematical study of models of computation and meaning of programming languages. Mathematical model which can describe the possible computations as described by the language, can give formal semantics of a given language.
Cognitive Informatics – Definition/Explanation/Meaning
Cognitive Informatics is considered as a study of information and cognition sciences. It is a kind of multidisciplinary. It includes investigation of human information processing systems along with their engineering implementations in computation.
Cognitive Informatics is nothing but the study of computational processes which can underlie human-like procedures for the purpose of processing information. It also includes the study of computational processes which can underlie computational systems that have capability to augment or mimic such kind of methods. It can be considered as a new multidisciplinary field which is related to natural systems like living organisms, and to artificial systems like computational devices and to the hybrids of both of them, as like assistive technology. Main objective of Cognitive Informatics is developing unified account of information processing and pattern which can explain about structure and organization of communicative information like language, speed, chemical and biological structures.
Main objective of Cognitive Informatics, with regard to technology, is to implement engineering solutions like web, text and data mining, multimodal interactive systems, communicative robots, multimedia, real time or virtual environment for the purpose of distributed collaborative work.
