SSDs are primarily utilized in portable computers, making them lighter, more durable, and more efficient. Portable computing today includes laptops, notebooks and netbooks, many weighing less than 4 pounds and providing longer battery life. The core of a computer is the Central Processing Unit, or CPU. OPEN-TEXTBOOKS David Bourgeois’ Information Systems for Business and Beyond: “Chapter 1: Exercise 3” Complete the following exercise: We all interact with various information systems every day: at the grocery store, at work, at school, even in our cars (at least some of us).

Microphones can be used to record audio or give voice commands. Move Over Moore’s Law: Make Room for Huang’s Law. Link to folder with slides for selected chapters in textbook. Netbooks (short for Network Books) are extremely light because they do not have a hard drive, depending instead on the Internet “cloud” for data and application storage. Some computers combine the two storage technologies, using the SSD for the most accessed data (such as the operating system) while using the hard disk for data that is accessed less frequently.

These cards were known as Network Interface Cards (NIC). As cell phones evolved they gained a broader array of features and programs. Moore’s Law has been generalized into the concept that computing power will double every two years for the same price point. See textbook adoptions As wireless technologies began to dominate in the early 2000s, many personal computers also began including wireless networking capabilities. The time it takes for data to be transferred from memory to system measured in Megabytes. ◦ Chapter 5: Networking and Communication – Today’s computers are expected to also be communication devices.
