Welcome back to Tech-Knowledgy, where I answer your questions about tech. I continue to get many great questions from readers and I am posting the questions and answers below so others can learn and/or respond. Feel free to post your tech questions in the Comments section or email me at firstname.lastname@example.org.
Q. I really have been enjoying reading your blog and I want to subscribe so I can get emails when there is a new article, but I am a little confused. I put my cursor on that orange square with stripes next to the About button, and it said Subscribe to The Wonder of Tech RSS. I clicked on it and then I went to a screen where your blog looks really different. What is RSS and how do I subscribe to your blog?
A. I am very glad you are enjoying the blog. Here is how to subscribe so you receive an email when I post a new article:
– On the sidebar, under my picture, is a place to enter your email address.
– Type in your email address and click Subscribe
– You will get a confirmation email from email@example.com with a link in the email.
-Click on the link to confirm your subscription.
You will then receive an email notification when a new article is posted to The Wonder of Tech.
RSS stands for Really Simple Syndication and is how you can easily get news feeds to post to a web page, such as My Yahoo or Google Reader, so you don’t have to search the web for updated articles. RSS readers are a great way to keep with your favorite blogs and news sites.
Here is a You Tube video that explains RSS well. Two warnings about the video: first, he goes fast so you may need to watch the video more than once to follow along. Second, he does use one term you may not be familiar with – URL. That is an acronym for Uniform Resource Locator, which is the address of a web page. It’s what you see in the address bar above.
Other than those two warnings, this is a great video to help you understand RSS:
Q. What is the difference between memory and hard drive? I have an old computer that has plenty of space left on it, but it loads web pages very slowly. Someone told me I need more memory for my computer but I don’t know what that is.
A. Many people get confused between computer memory and hard drive space. In fact, I was listening to a tech expert earlier this week talk about the two and he accidentally confused the terms in his talk. He realized his error and quickly corrected himself, but the two terms can be confusing.
Think of hard drive space on your computer as shelves in a library. Your files, such as pictures, music, documents, video, software, etc., are like the books that fill up those library shelves. The bigger your hard drive space, the more files you can store on your computer.
Memory is the space used for the files you have open on your computer. If you are someone who has a lot of windows or tabs open on your computer at one time, listening to music on your computer while you surf the web, you need more memory than someone who just keeps one window open and is working on a word processing document. I think of memory as the horsepower for your computer. The more memory you have on your computer, the more horses you have to power your computer and the easier it is for your computer to perform several functions at once. If you are a serious online gamer, you need a lot of memory for the best experience. If you are mostly using your computer to check email and create spreadsheets or word processing documents, you need less memory.
If you are thinking of buying a new computer, you should look for a computer that has at least a 320GB hard drive and 2GB of RAM (memory).
Q. There are so many recipe websites out there. I don’t want to check them all, but I like being able to search for recipes, read reviews of them and see videos. Any suggestions?
A. Yesterday Google introduced a new way to search recipes. If you search the title of the recipe on Google, say “Chocolate Chip Cookies”, Google will show you the results of your search. Look at the left column of the results page and click on Recipes. You will then be taken to a results page with the top rated recipes and be able to select the results by ingredients, preparation time, and calories.
