Almost all computer processing involves simple operations such as adding two numbers or comparing two numbers to see which is larger. What makes today’s computer so valuable is that they’re fast and incredibly reliable. Even the least expensive personal computers can perform several million operations per second‚ and can do so for years without making an error caused by the computer’s

Computer Memory Basics Although memory is technically any form of electronic storage‚ it is used most often to identify fast‚ temporary forms of storage. If your computer’s CPU had to constantly access the hard drive to retrieve every piece of data it needs‚ it would operate very slowly. When the information is kept in memory‚ the CPU can access it much more quickly. Most forms of memory are intended to store data temporarily. As you can see in the diagram above‚ the CPU accesses memory according

PART 1 : WORK PATTERNS Lesson 1: Computers on the Job: How Workers use computers The companies that use large computer system today are mostly the same companies that used them 30 to 40 years ago: corporations that have the big budget. These organizations – typically banks; insurance firms and aerospace companies – were the pioneers. The computers used were potent by then-current standards‚ even though today’s personal computers would provide a competitive edge. This turned out to be

Generally‚ the intent of the worm is to be malicious. There are some worms however‚ which do not have malicious intent. They are referred to as anti-worms. Computer worms are classified as a type of computer virus‚ but there are several characteristics that distinguish computer worms from regular viruses

Calculating the Probability of a Type II Error To properly interpret the results of a test of hypothesis requires that you be able to judge the pvalue of the test. However‚ to do so also requires that you have an understanding of the relationship between Type I and Type II errors. Here‚ we describe how the probability of a Type II error is computed. A Type II error occurs when a false null hypothesis is not rejected. For example‚ if a rejection region
