What is Data Communications? Next Topic | TOC The distance over which data moves within a computer may vary from a few thousandths of an inch‚ as is the case within a single IC chip‚ to as much as several feet along the backplane of the main circuit board. Over such small distances‚ digital data may be transmitted as direct‚ two-level electrical signals over simple copper conductors. Except for the fastest computers‚ circuit designers are not very concerned about the shape of the conductor or

Module 5 Data Security What is a computer security risk? A computer security risk is any event or action that could cause loss of or damage to computer hardware‚ software‚ data‚ information‚ or processing capability. Some breaches to computer security are accidental‚ others are planned intrusions. Some intruders do no damage; they merely access data‚ information or programs on the computer before logging off. Other intruders indicate some evidence of their presence either by leaving a

Analysis of Data The researcher distributed 150 questionnaires to people and students from different schools. After collecting the papers‚ each was tallied one by one. The questionnaire has a total of Seven(7) questions each with a different set and amount of answers. One hundred(100) questionnaires were distributed in person while the Fifty(50) were answered online. The results of the survey will be explained by percentage and shown through pie chart as well along with a slight conclusion for

Sensory Skills and the Parent-Infant Relationship A healthy baby is born with all of the basics necessary for sensory skills. These skills continue to develop in the early months of his life. Some of his senses may be more mature than others‚ but they all prove important in helping him learn about and make connections in his world. Although every baby is different‚ simple interactions can help him to develop his sensory skills in infancy. These interactions are not only crucial to developing sensory

Chapter 14 Factor analysis 14.1 INTRODUCTION Factor analysis is a method for investigating whether a number of variables of interest Y1 ‚ Y2 ‚ : : :‚ Yl‚ are linearly related to a smaller number of unobservable factors F1‚ F2‚ : : :‚ Fk . The fact that the factors are not observable disquali¯es regression and other methods previously examined. We shall see‚ however‚ that under certain conditions the hypothesized factor model has certain implications‚ and these implications in turn

DATA SECURITY IN LOCAL NETWORK USING DISTRIBUTED FIREWALLS ABSTRACT Computers and Networking have become inseparable by now. A number of confidential transactions occur every second and today computers are used mostly for transmission rather than processing of data. So Network Security is needed to prevent hacking of data and to provide authenticated data transfer. Network Security
