COMPUTER INPUT PERIPHEARLS

COMPUTER MONITOR

A monitor or display (sometimes called a visual display unit) is an electronic visual

display for computers. The monitor comprises the display device, circuitry, and an enclosure.

The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older

monitors use a cathodray tube (CRT), typically about as deep as the screen size.

MOTHERBOARDA motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the

crucial components of the system, while providing connectors for other

peripherals. The motherboard is sometimes alternatively known as the main board, system board, or, on

Apple computers, the logic board.[1]It is also sometimes casually shortened to

mobo.[2]

CENTRAL PROCESSINGThe central processing unit (CPU) or the processor is

the portion of a computer system that carries out the instructions of a computer program, and is the primary

element carrying out the computer's functions. It is the unit that reads and executes program instructions. The data in

the instruction tells the processor what to do. The instructions are very basic things like reading data from

memory or sending data to the user display, but they are processed so rapidly that we experience the results as the smooth operation of a program. This term has been in use in the computer industry at least since the early 1960s. [1]

The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their

fundamental operation remains much the same.

WEB CONTENTWeb Content is the

textual visual or aural content that is

encountered as part of the user of the

experience on websites. It may include, among other thing’s: images,

sounds, videos and animations.

THE PAGE CONCEPT

Web content is dominated by the "page" concept. Having its beginnings in an academic settings, and in a setting

dominated by type-written pages, the idea of the web was to link

directly from one academic paper to another academic paper. This was a completely revolutionary idea in the late 1980s and early 1990s when the best a link could

be made was to cite a reference in the midst of a type written paper and name that reference either at the bottom of the page or on the last page of the academic paper.

HTML WEB CONTENT

Even though we may embed various protocols within web

pages, the "web page" composed of "html" (or some variation) content is still the dominant way whereby we share content. And while

there are many web pages with localized proprietary structure (most usually,

business websites), many millions of websites abound

that are structured according to a common core idea.

A WIDER VIEW OF WEB

CONTENTWhile there are many millions of pages that are

predominantly composed of HTML, or some variation, in general we view data, applicatios, E-Services, images (graphics), audio and video files, personal web pages,

archived e-mail messages, and many more forms of file and data systems as belonging to websites and web pages.

While there are many hundreds of ways to deliver information on a website, there is a common body of knowledge of search engine optimization that needs to be read as an advisory of ways that anything but text should be delivered. Currently search engines are text based and are one of the common

ways people using a browser locate sites of interest.

CONTENT IS KING

The phrase can be interpreted to mean that - without original and desirable content, or consideration for the rights and commercial interests of content creators -

any media venture is likely to fail through lack of appealing content, regardless of other design factors.

Content can mean any creative work, such as text, graphics, images or video.

"Content is King" is a current meme when organizing or building a website[(although Andrew Odlyzko in

"Content is Not King" argues otherwise). Text content is particularly important for search engine placement.

Without original text content, most search engines will be unable to match search terms to the content of a

site.[4]

WEB DESIGN PRINCIPLES

In reality, there are no steadfast rules for how you must design a

web site. However, there are Web Design Principles to be followed

that will make your web site meet the needs of your viewers, easy to

navigate and increase the popularity of your site. If you do not follow these guidelines, you

will not be in the web design business for long, because no one

will ever hire you as a web designer.

TEN MISTAKES MADE BY WEB DESIGNERS

Make sure you fill your page

horizontally before you fill it

vertically

CLASHING COLOR This most often

happens with text against a poorly

suited background, see the example the web design principles

page.

UNTITLED PAGES Most simply forget to title

your page
