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

DATA COMMUNICATION & NETWROKING COMP 310 ASSIGNMENT #2 ST.GEORGE’S UNIVERSITY LEOPOLDO PIRELA DUE DATE: SEPTEMBER 21ST‚ 2013 What is the phase shift for the following? a. A sine wave with the maximum amplitude at time zero b. A sine wave with maximum amplitude after 1/4 cycle c. A sine wave with zero amplitude after 3/4 cycle and increasing Solution: a. There is no phase shift at time zero b. (¼) 360 = 90 90 x 2π / 360 = 1.57 rad c. (¾) 360 = 270 270 x 2π / 360 = 4. 7 rad

CHAPTER 2 SYSTEM ANALYSIS 2.1 INTRODUCTION Systems analysis is a process of collecting factual data‚ understand the processes involved‚ identifying problems and recommending feasible suggestions for improving the system functioning. This involves studying the business processes‚ gathering operational data‚ understand the information flow‚ finding out bottlenecks and evolving solutions for overcoming the weaknesses of the system so as to achieve the

Data collection is any process of preparing and collecting data‚ for example‚ as part of a process improvement or similar project. The purpose of data collection is to obtain information to keep on record‚ to make decisions about important issues‚ or to pass information on to others. Data are primarily collected to provide information regarding a specific topic. Data collection usually takes place early on in an improvement project‚ and is often formalized through a data collection plan which often

PRINCIPLES OF DATA QUALITY Arthur D. Chapman1 Although most data gathering disciples treat error as an embarrassing issue to be expunged‚ the error inherent in [spatial] data deserves closer attention and public understanding …because error provides a critical component in judging fitness for use.

electronic age has brought forth many technological advances. With these advances came the need for security and tighter control on how we send information electronically over the Internet or through a network. Date encryption is‚ in its simplest terms‚ the translation of data into a secret code. In order to read an encrypted file‚ the receiver of the file must obtain a secret key that will enable him to decrypt the file. A deeper look into cryptography‚ cryptanalysis‚ and the Data Encryption Standard
