Personal computers are electronic devices that are designed to be used by one person at a time to perform multiple tasks like creating documents, browsing the internet, and managing finances. They use a microprocessor as their central processing unit and come in various forms like desktops, laptops, tablets, and smartphones. Personal computers run operating systems like Windows, macOS, Linux, iOS, and Android and are used for both personal and professional purposes.

Personal Computers
The desktop PC went through typical product life cycle stages from introduction in the 1970s-1980s to current maturity. In the introduction stage, early desktop PCs were expensive kits until assembled models emerged in the 1980s from companies like IBM and Dell. In the growth stage of the late 1980s-1990s, desktop PC technology advanced with hardware improvements, expansion of components, and mass production which increased affordability and adoption. Now in the maturity stage, desktop PCs face competition and potential decline as laptops gain popularity for their mobility in both personal and business use.
Benefit thru-communication-improvement
Communication is omnipresent in every business. While a lot is said and done about Communication Skills improvement, the area of improving Communication Process or the Communication Systems within an organization remains vastly ignored. There are sustainable benefits that can be achieved by improving the business communication system. Some organizations have already realized impressive benefits such as 100%+ improvement in operational efficiency and 50%+ improvement in sales. We cover the latest happenings, how a company can achieve these benefits and the common mistakes that need to be avoided.
Introduction to Personal Computers in the Classroom
The document discusses how computers work through an input-processing-storage-output cycle. It describes the main hardware components of a computer including the CPU, RAM, storage devices, input devices like keyboards and mice, and output devices like monitors and printers. It also explains the basic software components like the BIOS, operating system, and applications. The document emphasizes that teachers need a basic understanding of computer hardware and software to effectively integrate technology into the classroom.
History Of Personal Computers
The document discusses the history of personal computers from their introduction in 1975 to modern times. It notes that the first personal computer was the MITS Altair which had 256 bytes of RAM compared to today's computers that have 1-2 gigabytes on average. In the late 1990s, 60% of households owned personal computers, which increased to 62% by 2003. Personal computers have significantly increased in power and decreased in price over time, becoming ubiquitous tools that over half of American adults now own.
Personal Computers
The document discusses the history and development of personal computers. It notes the first microcomputer in 1976 and some key PCs including the Apple II in 1977 and the IBM PC in 1981. It shows graphs of the Japanese PC market from 1990 to 2011, including units sold and average price. It also lists desired features for a new PC, such as a TV tuner, large screen, wireless accessories, Windows and Office. Finally, it briefly mentions additional topics like the PC market situation, combinations with communication services, and desktop publishing.
Personal computer
