I did my “Each One Teach One” assignment on the personal computer, or the PC. Everybody knows what as personal computer is, but the official definition of a PC is a digital computer designed for use by only one person at a time.
In the early 1970s, computers were large and really expensive. They would take up entire walls of big rooms, and the cost of making one was crazy high. They were owned by basically exclusively large corporations, universities, and government agencies.
The personal computer industry truly began in 1977, with the introduction of three preassembled mass-produced personal computers: Apple Computer, Inc.’s (now Apple Inc.) Apple II, the Tandy Radio Shack TRS-80, and the Commodore Business Machines Personal Electronic Transactor (PET for short). All 3 of these machines used eight-bit microprocessors.
IBM Corporation, the world’s dominant computer maker, entered the market in 1981 when it introduced the IBM Personal Computer, or IBM PC. The IBM PC was significantly faster than rival machines, had about 10 times their memory capacity, and was backed by IBM’s large sales organization. The IBM PC became the world’s most popular personal computer very quickly.
By 1990, some personal computers had become small enough to be completely portable. They included laptop computers, also known as notebook computers, which were about the size of a notebook.
By 2000, more than 50 percent of all households in the United States owned a personal computer, and this penetration increased dramatically over the next few years as people in the United States (and around the world) purchased PCs to access the world of information available through the Internet.
There are many pros and cons of the personal computer. The biggest benefit is the communication: a personal computer provides you with the ability to stay in touch with hundreds of people. You can send emails and instant messages to a specific person for personal or professional reasons. You can also send a message to many people at one time, you can write a blog or article or leave a post in a forum.
There’s also a lot of information constantly at your fingertips. In just a few seconds, you can type a website URL into the search bar of your browser and visit a website full of information. There are online encyclopedias, books and user-submitted communities designed to provide specific types of information, such as video game walkthroughs.
PC’s also provide a lot of fun. Computers provide a wealth of opportunities for fun and relaxation. You can play computer games, watch digital TV shows or movies, draw using a tablet and digital artwork software, create your own video or write a digital diary.
For personal computer cons, there are physical side effects that can have a negative impact on a person’s life. Frequent computer use leads to a variety of physical problems such as wrist soreness, back aches, tension headaches and tight hamstrings. Laptop users are especially prone to problems because they must hunch in order to appropriately view the screen. People who spend all day on the computer are susceptible to tight muscles, strained eyes and carpal tunnel syndrome.
Another issue is internet addiction. Internet and computer addiction plague a small percentage of computer users and mildly affect many other users. Severe Internet addiction may include addiction to cyber-relationships, online gaming, online gambling or adult content found on the Internet. Though mild Internet use is healthy and normal, people who are addicted to the Internet feel as if they must constantly be on the Internet. This often leads to decreased work or school performance or losing touch with friends and family members.
Whenever a person uses their PC, they spend less time in the physical world. Personal computers often keep people from more traditional methods of having fun such as playing games with friends, reading books, watching TV or exercising. People with computers typically spend less time with their family and friends and may instead elect to communicate digitally, which does not provide the tone and body language required for effective conversation.
