Video Summary 3 In the video it explained the purposes, functions, and characteristics of a central processing unit (CPU). The CPU is a piece of hardware that carries out instructions to the computer and is considered the brains of the computer.

Accounting data helps drive every decision from prioritizing current shortfalls to long term forecasting. The video provided an example from the perspective of a loan bank officer.

In this video we learn the meaning of raid, what it does, and how to efficiently configure raid arrays. RAID stands for Redundant Array of Independent Disks. The three most common types of RAID; RAID 0, RAID 1, and RAID 10. Different raid configurations offer different advantages, like speed and reliability. RAID 0 is all about speed, by striping the data across 2 drives you can keep all of the capacity and double the read and write performance. However, RAID 0 provides no reliability, if one of your drives fail you will all of your data. RAID 1 in the other hand provides maximum reliability, but no performance increase. When both performance and reliability are needed, there is the option for a RAID 10 configuration. To configure a RAID 10 array, you need four drives, stripe the data on all four drives and mirror two against two. This RAID configuration allows you to get about double the performance and capacity of an individual drive, and you can lose up two drives without losing any data. 3. 3 topics mentioned in the video. * The meaning of RAID * Pros and cons of RAID configurations * How to configure RAID 4. 3 terms used in the video and their definitions. * Data striping: The technique of segmenting logically sequential data, such as a file. * RAID: Data storage virtualization......

Commanding Heights

...Commanding Heights Summary Commanding Heights is a six hour PBS television program. This program was based on the book The Commanding Heights, The Battle for the World Economy, by Daniel Yergin and Joseph Stanislaw (1998). The program consistently discusses the importance of globalization, without really giving a definition of globalization. The term of globalization is not neutral, it can mean different things to different people. As stated by The Globalization Website: “Globalization broadly refers to the expansion of global linkages, the organization of social life on a global scale, and the growth of a global consciousness, hence to the consolidation of world society. Such an ecumenical definition captures much of what the term commonly means, but its meaning is disputed. It encompasses several large processes; definitions differ in what they emphasize. Globalization is historically complex; definitions vary in the particular driving force they identify. The meaning of the term is itself a topic in global discussion; it may refer to "real" processes, to ideas that justify them, or to a way of thinking about them. The term is not neutral; definitions express different assessments of global change. Among critics of capitalism and global inequality, globalization now has an especially pejorative ring” (Lechner, 2000-2001). Episode 1 The first hour of episode 1, The Battle of Ideas, covered various aspects of different world economies and why globalization was......
