Computer Monitors & Displays
Chandre, Seth, Lashaina, Jonathan, Ingrid4th PeriodMonitors
The monitor of an computer is essential but at the same time its not. Well because in simple terms the monitor allows you to see what you are doing. Then again its not because you can change your monitor as many times as you would like and it wouldnt effect your computers performance, programs, or files in any way.Monitors are usually connected to a video card, which has been snapped into a slot in the motherboard, allowing the computer to send the display to the monitor.CRT (Cathode-ray tube).There are two types of monitors but the most common is the CRT (Cathode-ray tube). They provide a excellent display and have conquered the market since the beginning of computers. On the other hand, they use a lot of power, discharge a lot of heat, and take up a lot of room.
LCD (Liquid Crystal Display) MonitorThe second type of monitor taking more and more of the sell is the LCD (Liquid Crystal Display) Monitor. It is becoming more trendy because it takes up less room and many people feel it is easier on their eyes.By the way its a plasma screen.
Gas Plasma ScreensAnother smooth board design on the rise is Gas Plasma screens, they provide the largest screens, out of the other monitors. But are not cost effective, As a result they are not widely used.
The Internet and the World Wide Web
IntroductionIn simple terms ,the Internet is millions of computers all around the world linked together. Getting all those computers to communicate and work together is not a small task. It is impossible to find out how many computers make up the Internet because nobody knows. No one person, company, or entity owns or controls the Internet. There is no one in charge! It does not have a center. It is astonishing the Internet actually works. The great thing about the Internet is that it is open to anyone who has access to a computer and a telephone. Even if you don't own a computer or don't have Internet access, there are schools, libraries, Internet Cafes, and other places that have Internet access at little or no cost.
The Internets Hardware
Much of the hardware technology that makes up the Internet are owned or shared by thousands of private and public organizations. There are supercomputers called NAPs (Network Access Points), that serve as major hubs. The NAPs are connected to each other and to Regional Routers through the largest lines of the Internet called Backbones. The Regional Routers are connected to Regional Networks. These Regional Networks connect to the various ISPs(Internet Service Providers)from which you buy your Internet access. These ISPs then connect to your home telephone or cable .The farther away the lines get from the main backbone line the lower their capability becomes.Most of the computers on the Internet carry out one of three functions. They either demand data, give data, or help send data to the network. An example is your personal computer at your house ,a computer that primarily requests data, which is called a Client. Computers that provide data are called Servers, since they Serve data to other computers. Computers that help information travel across the Internet are called Routers. Every time data is going in the wrong direction on the Internet, a Router is there to send it in the right direction.
Web Design and Development
Building a web site should be carefully planned project. Many hours of planning, research, and preparation must be invested before any work on the computer begins.
7 Steps in Building a Web Site
Determine the Problems, Define the Purpose/GoalsMost web sites are built to solve a problem. The goals of the web site should be to gain a persons attention ,inform them, help them persuade them, and even entertain them.
Gather Info & Research perform an in-depth interview about all aspects of your business.. Next, it is always important to find out as much about who you are building the site for as you possibly can. This is called the target audience, or in this case, his current/potential customers. Your primary goal in this step is to Identify/Understand the target audience. It is essential to find out what % of his customer are children, teens, young adults, middle aged adults, and senior citizens.
Shape Solution, Determine Content, Choose Technology, Story board/Map Site
Yes, we could build you a web site that would showcase your fine services, inform people of your services and location, and allow them to make appointments online. For your current customers, we could allow them to log in and view their next appointment and we could automatically send them an e-mail reminder. Your focus should be to determine content for the site, choose technologies to use, and map out the site. Gather AssetsThis would include taking digital images of the office, collecting information such as hours of operation, history of the practice, and other important information that need to be placed on the site.
Construct SiteKeeping the purpose in mind, construct a site based upon the Site Map you have already devised.Test, Improve, Test, Improve, Etc.As portions of the site nears completion, you must test every page, link, button and all other parts of the site. Carefully study the site, asking yourself, is there any way I can make improvements? Once the site is complete, it is always a good idea to have a few people test it out, just to get their opinion on how easy it is to use and if it makes sense to them. They may see some things that can be improved. After you have taken their opinions about the improvements, show the site to your client. He may have some things that he wants you to change. Make those changes and you are almost finished.Publicize the SiteDiscuss with your client the a variety of ways to publicize the site such as search engine submission, placing the web address on business cards, office paperwork, in the newspaper ads, etc.
