Answer 1

2.A. Multimedia refers to any element on that is different from written, textual content. It includes elements such as

Images

Graphics & Infographics

Videos

Interactive Content

Images

Images are one of the best, and most common forms of multimedia - and for good reason. They provide a great way to break up walls of text and give a visual representation of whatever information you're sharing. Images can help users picture exactly what you're talking about, and they add color and interest to a pages

They also keep users from being bored if they're scrolling through a page in Internet that's extremely text heavy

Every page on Internet should have images to keep users interested and engaged.

Graphics & Infographics

Graphics and infographics are one of the best ways to keep users engaged to Internet

Graphics are typically illustrated images that can be used anywhere on Internet, They include graphs, charts, illustrated images, animated graphics, and more. Their purpose is to help keep users on a page by engaging them via visual elements.

Infographics are far more informational than regular graphics, and are a great way to share information in a compelling, visual way. You can use regular-sized infographics on your website, or you can opt for mini-infographics, which allow you to share tidbits of information in a small space.

Videos

Videos are another great way to engage users on Internet, They can cover any kind of topic from demos of products or services

Videos are also a great way to decrease bounce rate on your site's pages, and increase time-on-page, along with user engagement and interaction

Interactive content

Interactive content refers to anything that a user can interact with. This may be a custom pricing calculator or a short survey. This kind of multimedia adds interest to your page, and allows users to truly become a part of your website. They'll also gain something from it as well.

Multimedia is important to for internet in many reasons, but a few in particular.

First, without multimedia, Internet will likely look like a huge wall of text. This can easily intimidate site users, and they might even navigate away from site to find information elsewhere. Multimedia allows you to break up text in a way that allows users to consume it at a slower pace, instead of feeling overwhelmed. It also provides something for them to engage with that isn't textual content.

Next, multimedia makes for a great user experience

Multimedia can also help decrease bounce rate because it entices users to stay on the internet for a longer period. If you're looking at page with nothing but text, you'll either be too bored to read the whole thing, or find what you're looking for quickly and navigate away from the intrrnet. With multimedia, you'll provide something else for users to interact with. Infographics, videos, and interactive content can all keep users on your Internet for longer because they provide a secondary visual element for users to look at besides text.

3.A. We use lossy Compression or lossless compression for image because, Lossy compression is most commonly used to compress multimedia data I.e audio, video, and images especially in applications such as streaming media and internet telephony And also lossless compression is typically required for text and data files, such as bank records and text articles.Lossless compression is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data. By contrast, lossy compression permits reconstruction only of an approximation of the original, Both are used for image

4.A.Comparision Between Bitmap and vectors In general, a bitmap graphic is much larger than a similar vector graphic.
Bitmap graphics are affected by resolution. If you enlarge a bitmap graphic, it will look jagged. When shrunk, its features become indistinct and fuzzy. This does not happen with vector graphics as their shapes are redrawn to compensate for changes in resolution.
Altering vector graphics is easy because the shapes within them can be ungrouped and edited individually. However, vector graphics are difficult to modify or even display when they are not opened in programs that understand their rendering languages. For example, while many Mac OS drawing programs easily display and edit PICT files, few are able to do anything at all with WMF files. Most paint applications, however, are capable of opening many different kinds of bitmap graphic formats.
You can easily convert one kind of bitmap file into another. You can also convert a vector graphic into a bitmap. However, it is very difficult to convert a bitmap graphic into a true vector graphic. It is even difficult to convert one kind of vector graphic into another (e.g., PICT to WMF).
Vector graphics are not appropriate for complex images (e.g., digitized photographs).
