What is a Window. Using Alt & Tab to switch between Windows. Libraries – A new feature. Adding more locations. Have decided to teach LibreOffice, instead of Microsoft Word. This week – The Internet • Is a vast array of interconnected Computers. • Main uses are = • World Wide Web. Hence the www in site names. It common now to refer to this just as the Internet. Email – Sending letters by a computer. To be covered in detail in week 6. World Wide Web • Vast collection of information to search for. • Copies of what you search for are widespread so it’s hard for information to go completely missing. • Once something is published it can never be withdrawn. • To view you need a computer connected to the Internet and a Browser program – Usually Internet Explorer IE. Are others – Firefox, Opera & Google Chrome but no great need to change. • Currently the latest version of Internet Explorer is V11. Internet Explorer Layout Back to Earlier Later Dropdown list of earlier pages Pages. Refresh URL or Web Site RH Click here to get this list Current page Another tabbed page behind Menu bar Command bar Print Find on this page (Preview) A Secure site- Lock symbol or GO or Compatibility symbol Tools Options Go to Home page Favorites Using Internet Explorer • The top dark blue row at the top shows the current web page “Title”. Hopefully the web designer has put something descriptive. • If you have been visiting many pages you can use the big arrows to go back/forwards over the sites visited. Unfortunately this does not work completely if you have been in “Secure” web sites as used by Banks. They start with HTTPS:// and have a Lock Symbol in orange. Usually they provide a link to go back to earlier pages in the body of the page and may even warn you not to use the arrows. You will get warnings when entering and leaving “Secure” pages – answer “Yes”. Next is a down arrow which show a list of previous pages. You can select as required. Next is a Green Refresh which forces the page to be reloaded. In the next long box is the web site you are currently at. Just as every residence has a unique street address, every webpage has its own web address. That address is called the Uniform Resource Locator (URL) or simpler – Web Site. Eg the URL for the Microsoft main website is http://www.microsoft.com If you know the URL for a page, you can type it directly into Internet Explorer . Then, Click the Green Go button or press ENTER to go to the website. You don't have to type http:// For example, you can type www.microsoft.com and Internet Explorer will fill in the rest. The URL or web site address has to be entered exactly with no spaces. The case does not matter so it’s simplest to use lower case or small letters throughout. Because the URL has to be exact most people use a search engine instead. EG its easier to just search for “U3a Nantwich” than to type http://www.creweandnantwich-u3a.org.uk/ in the address bar. Tabs • Tabs. Allows to switch between several active web sites. Here I am on a page about Ebay. If you click on a new tab here you get an empty new page to work with. You can go back to eg Cat - Wikipedia by clicking on it again. Many new Tabs are allowed. • But you could just start another Internet Explorer running. Best use one for each subject & tabs for detail of that subject. First Page shown • When you start Internet Explorer, it goes to whatever webpage is set as the home page. • To get back to your home page at any time, click the Home button (has a House Icon). • To change your Home page it’s not too difficult. Get the web page you want. Click on Tools, Internet Options, Use current, OK. • Installing some software will try to change your home page, always for their advantage. Answer no. Search Engines • Search engines enable you to find relevant information on the Web easily. You type a few key words (or phrases) and the Search engine returns pages which it thinks a will be relevant. • From Internet Explorer 10 the long web site box can also be used for entering a search term, then press enter. It will then search using “bing”. • Google is the leader in “Search Engines” but “Ask Jeeves” is better at searching a phrase. • https://www.winhelp.us/internet-explorer-11search.html configure IE Search capabilities • With Google, if a phrase in enclosed in quotes then it will search for the exact phrase only, not just the individual words in any order. Eg "discover and learn about London" is in 5 places only. Try this without the quotes, you get 66,300,000 matches. • Putting a “+” sign in front of a word will only find articles containing that word. Similarly “-” will only find articles NOT containing that word. This is very useful because a problem of search engines is too many results. Google has an Advance Search which uses this. • If its a brand name you are searching for, Google will do its best to include Adverts. • The last part of a website name has a . Followed by groups of 2 or 3 letters. .com was the original and stands for Company. • 2 letters define the type of site eg .ac = a college or university. .biz stands for Business • Last 2 letters define the country. Eg .uk • To search for web sites from one country only add eg site:.uk or site:au for Australia. • To search for a document only add eg filetype:pdf Favorites etc US spelling only • Internet Explorer (IE) allows a user adjustable list of Favourite web sites for easy access. • Another name for the same thing is “Bookmarks”. • Its the yellow star on the right Just select what you want and it will enter that site. Some are in Yellow Folders. • If you have found a interesting site and want to save it, click on “Add to favorites” and verify or change its name. • There is also a History Tab to allow easy access to site visited up to a week ago. Feeds, best Google it • RH click in a blank area just left of the “Home” button. Tick to get the Menu bar then. • Under “File”, Print is useful but beware web pages don't conform to A4 paper size and may waste lots of paper. Check this with Print PreView. Better to copy what you want to a Word document and print that. • “Edit” has cut, copy & paste as talked about last week. “Find on this Page” is useful. Try it later. • “View” In Toolbars & Explorer Bars, don't have too many ticked – they take up too much room. Full Screen is useful, use F11 to put back as was. Cookies • On the Internet its not a biscuit but small file defining to a website information about previous visits to that same site. • Its main use is to present you with relevant information, but that's mainly advertising. • Its also used to detect weather you have logged into a site. And prompt you to if required. • By law a website now has to ask you if you want to accept Cookies. Many sites will not work properly if you don't accept. Internet Explorer Tools • Click on the Cog to get tools. • If a site is not displayed correctly, try adding it to “Compatibility View” it’s in Settings. • You can “Pin” your most favourite site, eg Facebook to the taskbar. • In Internet Options you can delete previous Browsing History. As well as covering your tracks its sometimes clears web browsing errors if you have gone through a sequence of pages. • In Privacy, make sure “Turn on Pop-up Blocker is ticked. Practical • The world is your Oyster now! If you want to know something, somebody in the world is bound to know about it. Finding it is the real skill. Today, just a few ideas. You will need to type them in (or Google them). Try Find on this page, Forward/Back, Make as a Favorite, Another Tab, Change Home Page. • www.bbc.co.uk/ • www.google.co.uk • www.ebay.co.uk • http://en.wikipedia.org/wiki/Main_Page Quiz • When is Spring Half Term at St Thomas More school • What is the Amazon price for “Lawn Grub Killer 20Sqm • On http://www.facebook.com Login as email= [email protected] and password= u3a.Monday I am known as Brianu Mooreu.

It will now show in the Quick launch area at the bottom but have gone from the start menu. • Try “Tools” cog icon on RHS. Try Zoom, you might prefer a different setting. Look at “Manage add-ons” This is where you can change the default search engine. Note “Search in the address bar” is ticked. And ticking “Prevent programs from suggesting....” is a good idea.
