From the small business owner to the student creating a class project, or even casual individuals working on a blog or personal project online, HTML knowledge is incredibly useful. Although the prospect of having to learn a programming language certainly does seem daunting, the good news is that HTML uses common words so that it is fairly simple to pick up.
HTML was invented by Tim Berners-Lee in the late 1980s and early 1990s. The first "public" release was in 1991. It was based on an earlier markup language, SGML (Standardized General Markup Language).
The major innovation of HTML was its use of the hyperlink. We are so used to this now that it is hard to understand how revolutionary this idea was at the time.
The hyperlink allows any document to reference any other document, and provides immediate access to that other document. Hyperlinks are what make the World Wide Web a web, and not just a library or database.
The IETF took up HTML as a standard and published the first HTML proposal in 1993. HTML 2.0, the first full official specification was released in 1995. By 1997, the W3C had taken over stewardship of the standard, and HTML 3.2 was released.
HTML 4.0 was released towards the end of 1997, and again the following year with a few updates. This version of the standard, with its three variations (strict, transitional, and frameset) defined HTML most of the next decade.
It was the version in force during the rise of the web's most iconic properties: Wikipedia, Google, Facebook, WordPress, Myspace, AOL. If you learned how to build web pages before 2008, you almost certainly learned this version.
Alongside HTML 4.0 was a related project called XHTML. This was first released in 2000 and 2001, as an XML-based implementation of HTML 4.0. Since XML had a stricter syntax than HTML, and could be easily validated by an XML parser, it was thought that introducing XHTML would force web content authors to create more precise documents.
For the most part, this did not happen. In practice, XHTML — along with the three varieties of HTML4, and the wild variation in browser rendering — contributed to the general confusion concerning what was and wasn't "standard" HTML.
One notable effect of XHTML is the idea that you must "close" empty tags with a trailing slash. If you are in the habit of typing <br /> instead of just <br>, you can thank XHTML — it was an XML syntax requirement that all tags must be closed.

There are two types of cell references: relative and absolute. Relative and absolute references behave differently when copied and filled to other cells. Relative references change when a formula is copied to another cell. Absolute references, on the other hand, remain constant no matter where they are copied.

Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms. Determining the most likely cause is a process of elimination—eliminating potential causes of a problem. Finally, troubleshooting requires confirmation that the solution restores the product or process to its working state.

Troubleshooting is a systematic approach to problem solving that is often used to find and correct issues with complex machines, electronics, computers and software systems.
The first step in troubleshooting is gathering information on the issue, such as an undesired behavior or a lack of expected functionality. Other important information includes related symptoms and special circumstances that may be required to reproduce the issue.
Once the issue and how to reproduce it are understood, the next step might be to eliminate unnecessary components in the system and verify that the issue persists, to rule out incompatibility and third-party causes.
Continuing, assuming the issue remains, one might next check common causes. Depending on the particular issue and the troubleshooter’s experience, they may have some ideas. They may also check product documentation and/or conduct research on a support database or through a search engine.
After common causes are ruled out, the troubleshooter may resort to the more systematic and logical process of verifying the expected function of parts of a system. One common method is the split-half troubleshooting approach: With a problem resulting from a number of possible parts in series, one tests half-way down the line of components. If the middle component works, one goes to the middle of the remaining parts, approaching the end. If the test finds a problem at the mid-point, one does a split towards the start of the line until the problem part is found. The split-half process can save time in systems that depend on many components.
Once the problem part is identified, it may be adjusted, repaired or replaced as needed. Evidence of effective troubleshooting is indicated when the issue is no longer reproducible and function is restored one.

| Ino | Item | Quantity |
| 1 | Pen | 220 |
| 2 | CD | 530 |
| 3 | DVD | 450 |
| 4 | Duster | 110 |

Photoshop layers are like sheets of stacked acetate. You can see through transparent areas of a layer to the layers below. You move a layer to position the content on the layer, like sliding a sheet of acetate in a stack. You can also change the opacity of a layer to make content partially transparent.
