2. 3.1 Learning Outcomes Define digital devices; Identify the primary components of a computer system and the functions they perform; Explain the factors distinguishing computing power of computers; Describe the types of input, output, and memory devices; Discuss hardware trends including: mobile computing, integrating computing. Assess the impact of commoditization of computers; and Summarize the problem of eWaste.

3. 3.1 Introduction

4. 3.2 Digital Devices A digital device processes electronic signals into discrete values, of which there can be two or more. Photo by form PxHere

5. 3.3 Computers Computers are machines that accept data as input, processes that data using stored instructions, and outputs the information.

6. 3.3 Computers All personal computers consist of the same basic components: network connection motherboard central processing unit (CPU) storage/memory input/output devices

7. 3.3 Computers- Motherboard The motherboard is the main circuit board on the computer. The CPU, memory, and storage components, among other things, all connect into the motherboard.

8. 3.4 Processing Data The core of a computer is the Central Processing Unit, or CPU. It can be thought of as the “brains” of the device. The CPU carries out the commands sent to it by the software and returns results to be acted upon. “Faster & cheaper” computing is often referred to as 'Moore’s Law', after Intel co-founder, Gordon Moore.

9. 3.5 Storing Data Random Access Memory (RAM) When a computer boots up, it begins to load information from storage into its working memory. This working memory, called Random-Access Memory (RAM), can transfer data much faster than the hard disk. Possessed Photography

10. 3.5 Storing Data Cont. Hard Disk is used for long term storage. It is non-volatile. Solid State Drive is also used for long terms storage, but uses flash memory which is faster. USB drives or universal serial bus drives are removable storage.

11. 3.6 Computer Speed Factors How do the following devices contribute to the speed of the computer? CPU Motherboard RAM Hard disk

14. 3.8 Trends in Personal Computing A personal computer is designed to be a general-purpose device, able to solve many different types of problems. Some trends: portability, mobility and interconnectivity. Photo from pxhere.com

15. 3.9 Commoditization Over the past forty years, as the personal computer has gone from technical marvel to part of everyday life, it has also become a commodity. There is very little differentiation between computer models and manufacturers, and the primary factor that controls their sale is their price.

16. 3.9 E-Waste E-waste are the discarded electronics that usually end up in landfill. The amount of e-waste is growing due to the reduction in cost and high rate of innovation.

17. 3.10 Key Takeaways Hardware consists of the components of digital technology that you can touch. A personal computer is made up of many components the CPU, motherboard, RAM, hard disk, removable media, and input/output devices. Moore’s Law states that computing power will double every two years for the same price point. The CPU, motherboard, RAM and Hard Disk all contribute to the speed of your computer. Personal computing is trending towards more portability, mobility and interconnected devices. Advances in personal computing has made the personal computer a commodity as well as contributed to the problem of e-waste.
