Introduction to Mobile Computing

The proliferations of wireless networks and small portable computing devices have led to the emergence of the mobile computing paradigm. Mobile and nomadic users carrying laptops or hand-held computers are able to connect to the Internet through publicly available wireline or wireless networks. Mobile computing will be the buzz of the next century. Buzzwords such as mobile, nomadic, pervasive, and anytime anywhere, are used by different people to refer to the new breed of computing that utilizes small portable devices and wireless communication networks.

Mobile computing fundamentally differs from desktop computing. Mobile devices, e.g. PDAs, mobile phones and digital cameras have, compared to desktop computers low computational power, small memory and often no mass storage. Communication links to other mobile devices or to a stationary network are usually wireless, thus often unstable with low bandwidth.

What is computing?
Operation of computers.

What is mobile?
That someone/something can move or be moved easily and quickly from place to place.

Conclusion
If success in the computing field is defined by market share and consumer interest, there is no question that mobile computing has already exceeded most expectations and is well on its way toward becoming one of the most dominant forces of the entire information industry. From the array of palmtop computers available in budget superstores, to Intel's release of low-power mobile-oriented Pentium chips nearly immediately after the desktop-version release, to the exorbitant sums of money paid by cellular operators for leasing radio towers and buying frequency space, there is little doubt about the potential of ubiquitous mobile computing.

The challenges are complex, interrelated and exacerbated by often hard, physical limitations (such as the limited RF bandwidth). However, if we try to gauge the innovative potential of the computer industry by its past performance, it appears that that we have only begun to see the future of mobile computing.

MINOR DISORDERS OF NEW BORN AND ITS MANAGEMENT - NURSING ASSIGNMENT

-
INTRODUCTION         Neonatal health problems are frequently found ranging from minor physical or physiological peculiarities to the serious life threatening illnesses. Minor problems should not be ignored lightly without adequate assessment of the conditions. Early diagnosis and management of the serious problems help to overcome life long disability and to reduce neonatal morbidity and mortality. Nurses are responsible to manage the minor problems and to detect the serious problems for early and prompt management along with appropriate nursing interventions and support to the mother. MINOR DISORDERS OF NEW BORN 1. VOMITING         Vomiting is one of the common manifestations in the neonates. Regurgitation after feeds should not be confused with vomiting. Mucus vomiting often hinged with blood is quite common soon after birth. It is due to irritation often gastric mucosa by the swallowed materials during birth. Causes: ·         Dietic ·         Over feeding

KANGAROO CARE - NURSING ASSIGNMENT

-
INTRODUCTION         Caring low birth weight baby is a great challenge for the neonatal care unit and the family. Number of low birth weighs baby is still for beyond the expected target in our country. The cost of the quality management of these babies is increasing day by day. Kangaroo care is low cost approach for the care of low birth weight baby. This method of care was introduced and popularized by Dr.Edger Ray, Dr.Martinez and Dr.Charpak in late 1970s. DEFINITION         Kangaroo Mother Care (KMC) is a special way of caring low birth weight infants by skin to skin contact if promotes their health and welling by effective thermal control, breast feeding and bonding. KMC is initiated in hospital and continued at home. COMPONENTS OF KMC         In KMC, the infant is continuously kept in skin contact by the mother and breastfed exclusively to the utmost extent.         The two components of KMC are; 1.    Skin to skin contact is provi
