Internet Terms of U and V

Vlog

1. Vlog is short for "video blog" and is pronounced "vlog" (one syllable). 
2. A vlog is a blog, or web log, that includes video clips. It may be entirely video-based or may include both video and written commentary. Several types of vlogs are available on the Web, including instructional videos, travel updates, and personal commentaries.
3. People who create vlogs are known as "vloggers." 

VoIP

   

1. Stands for "Voice Over Internet Protocol," and is often pronounced "voip." 
2. VoIP is basically a telephone connection over the Internet. 
3. The data is sent digitally, using the Internet Protocol (IP) instead of analog telephone lines. This allows people to talk to one another long-distance and around the world without having to pay long distance or international phone charges.
4. In order to use VoIP, you need a computer, an Internet connection, and VoIP software. You also need either a microphone, analog telephone adapter, or VoIP telephone.
5. The largest provider of VoIP services is Vonage, but there are several other companies that offer similar services. While Vonage charges a monthly service fee, programs like Skype and PeerMe allow users to connect to each other and talk for free. However, these free services may offer fewer connections, lower audio quality, and may be less reliable than paid services like Vonage.
6. VoIP is also referred to as IP telephony, Internet telephony, and digital phone.

VPN

1. Stands for "Virtual Private Network" (not a successor to the UPN television network). 
2. VPN is a network term that most computer users don't need to know, but at least you can impress your friends by talking about it. 
3. A virtual private network is "tunneled" through a wide area network WAN such as the Internet. 
4. This means the network does not have to be located in one physical location like a LAN. However, by using encryption and other security measures, a VPN can scramble all the data sent through the wide area network, so the network is "virtually" private.
5. Businesses often use VPNs to communicate across multiple locations. For example, a large company that has offices in several cities may need to send data to the different locations via the Internet. To keep the information secure, the company might set up a VPN with an encrypted connection. This is similar to having a secure intranet over the Internet. On a smaller scale, individual users may have a VPN account with their company, which allows them to connect to their office computer from their home or another location. 
6. This is especially helpful for business travelers who need to access office data from their laptops.

UDP

1. Stands for "User Datagram Protocol." 
2. It is part of the TCP/IP suite of protocols used for data transferring. 
3. UDP is a known as a "stateless" protocol, meaning it doesn't acknowledge that the packets being sent have been received. 
4. For this reason, the UDP protocol is typically used for streaming media. 
5. While you might see skips in video or hear some fuzz in audio clips, UDP transmission prevents the playback from stopping completely.

UGC

1. Stands for "User Generated Content." 
2. In the early years of the Web, most websites were static, meaning each page had fixed content that did not change unless it was updated by the webmaster. As the Web evolved, dynamic websites, which generate content from a database, became the norm. Now, in the Web 2.0 era, many websites now include UGC, or content created by visitors.
3. Many different types of websites contain user generated content. 
4. One example is a Web forum, which allows users to discuss topics by posting comments online.
5. Another example is a wiki, which allows users to directly add and edit website content. Wikipedia, for instance, contains information written and submitted by thousands of authors around the world. 
6. Social networking websites like Facebook and LinkedIn, are also UGC websites that allow users to create personal profiles and share information with each other. 
7. These websites simply create a platform for users to add and share content with each other.
8. While wikis, Web forums, and social networking websites contain nearly all user generated content, many other sites now contain both original content and UGC. 
9. For example, blogs often include a section where visitors can post comments about the author's articles. 
10. News websites typically allow visitors to post their feedback below the news stories. Often, these hybrid pages eventually contain more user generated content than original content. 
11. Thanks to UGC, the Web is now a more interactive medium, allowing users to actively participate in the creation of website content.

Revising concepts

1. The primary storage devices are used to store information only when the computer is on. 
2. Secondary storage devices were developed to store data and information permanently on them.

UNITS OF MEMORY STORAGE

•  4 bits = 1 nibble
•  8 bits = 1 byte
• 1024 byte = 1 kilobyte (KB)
• 1024 kilobyte = 1 megabyte (MB)
• 1024 megabyte = 1 gigabyte (GB)
• 1024 gigabyte = 1 terabyte (TB)

Examples: Convert the following into their byte equivalents:
i.  240 KB
= 240 X 1024 bytes.

ii. 4.2 GB
= 4.2 X 1024 MB
= 4.2 X 1024 X 1024 KB
= 4.2 X 1024 X 1024 X 1024 bytes

iii. 1.44 MB
= 1.44 X 1024 KB
= 1.44 X 1024 X 1024 bytes

iv. 20 GB
= 20 X 1024 MB
= 20 X 1024 X 1024 KB
= 20 X 1024 X 1024 X 1024 bytes

v.  10 TB
= 10 X 1024 GB
= 10 X 1024 X 1024 MB
= 10 X 1024 X 1024 X 1024 KB

= 10 X 1024 X 1024 X 1024 X 1024 bytes

vi.  1.2 MB
= 1.2 X 1024 KB
= 1.2 X 1024 X 1024 bytes

Internet Terms Starting from W, X

XHTML

1. Stands for "Extensible Hypertext Markup Language." 
2. XHTML is a spinoff of the hypertext markup language (HTML) used for creating Web pages.
3. It is based on the HTML 4.0 syntax, but has been modified to follow the guidelines of XML, the Extensible Markup Language.
4. XHTML 1.0 is sometimes referred to as HTML 5.0.
5. XHTML pages must have perfect syntax. This means no missing quotes or incorrect capitalization in the markup language. 

Web Server
 

1. A Web server is a computer system that hosts websites. I
2. It runs Web server software, such as Apache or Microsoft IIS, which provides access to hosted webpages over the Internet. 
3. A fast Internet connection allows Web servers to support multiple connections at one time without slowing down.
4. Any computer can be used as a Web server, as long as it is connected to the Internet and has the appropriate software installed. 
5. However, most Web servers are 1U rack-mounted systems, meaning they are flat, trimmed down computers that can be mounted on a server rack. Most Web hosting companies have several server racks, which each contain multiple servers. This is the most space-efficient way to host a large number of websites from a single location.
6. Web servers typically host multiple websites. 
7. Web servers that host websites for multiple users are called "shared hosts." This is the most common type of hosting solution and is used for personal sites, small business sites, and websites run by small organizations.
8. Web servers that only host websites for a single person or company are called "dedicated hosts." These types of servers are appropriate for high-traffic websites and sites that require custom server modifications. 
9. Dedicated hosts are also more reliable than shared hosts

Web Host

1. In order to publish a website online, you need a Web host. 
2. The Web host stores all the pages of your website and makes them available to computers connected to the Internet. The domain name, such as "sony.com," is actually linked to an IP address that points to a specific computer. When somebody enters your domain name into their browser's address field, the IP address is located and Web site is loaded from your Web host.
3. A Web host can be hosted from anywhere from one to several thousand computers that run Web hosting software, such as Apache, OS X Server, or Windows Server. 
4. Most websites you see on the Web are accessed from a "shared host," which is a single computer that can host several hundred Web sites. 
5. Larger websites often use a "dedicated host," which is a single machine that hosts only one website. Sites with extremely high amounts of traffic, such as apple.com or microsoft.com, use several computers to host one site.
6. If you want to publish your own website, you'll need to sign up for a "Web hosting service." Finding a good Web host shouldn't be too hard, since their are thousands available. Just make sure the Web host you choose offers good technical support and ensures little or no downtime. You'll usually have to pay a monthly fee that varies depending on how much disk space and bandwidth your site will use. So it's a good idea to estimate how big your site will be and how much traffic you expect before signing up for a Web hosting service.

Web 2.0
 

1. Web 2.0 is term that was introduced in 2004 
2. Refers to the second generation of the World Wide Web. 
3. The term "2.0" comes from the software industry, where new versions of software programs are labeled with an incremental version number. 
4. However, Web 2.0 does not refer to a specific version of the Web, but rather a series of technological improvements.Some examples of features considered to be part of Web 2.0 are listed below:

Blogs - also known as Web logs, these allow users to post thoughts and updates about their life on the Web.
Wikis - sites like Wikipedia and others enable users from around the world to add and update online content.
Social networking - sites like Facebook and MySpace allow users to build and customize their own profile sand communicate with friends.
Web applications - a broad range of new applications make it possible for users to run programs directly in a Web browser.

1. Web 2.0 technologies provide a level user interaction that was not available before. 
2. Websites have become much more dynamic and interconnected, producing "online communities" and making it even easier to share information on the Web.

WAIS
 

1. Stands for "Wide Area Information Server." 
2. This is a program that can index enormous amounts of information and make it searchable across large networks (including the Internet). 
3. People can search the WAIS index and it will return results by relevance. Searches can then be narrowed down by subsequent searches on the original results. 
4. Search engines are a new and improved version of WAIS, specifically for the Web.

W3C
 

1. Stands for "World Wide Web Consortium." 
2. The W3C is an international community that includes a full-time staff, industry experts, and several member organizations. 
3. These groups work together to develop standards for the World Wide Web. 
4. W3C also provides standards for Web graphics (such as PNG images), as well as audio and video on the Web. 
5. The organization also develops standards for Web applications, Web scripting, and dynamic content. 
6. Additionally, the W3C provides privacy and security guidelines that websites should follow.

Wiki
 

1. A wiki is a Web site that allows users to add and update content on the site using their own Web browser. 
2. A great example of a large wiki is the Wikipedia, a free encyclopedia in many languages that anyone can edit. 
3. The term "wiki" comes from the Hawaiian phrase, "wiki wiki," which means "super fast." I guess if you have thousands of users adding content to a Web site on a regular basis, the site could grow "super fast."

WWW

1. Stands for "World Wide Web." 
2. It is important to know that this is not a synonym for the Internet. 
3. The World Wide Web, or just "the Web," as ordinary people call it, is a subset of the Internet. 
4. The Web consists of pages that can be accessed using a Web browser. 
5. The Internet is the actual network of networks where all the information resides. 
6. Things like Telnet, FTP, Internet gaming, Internet Relay Chat (IRC), and e-mail are all part of the Internet, but are not part of the World Wide Web. 
7. The Hyper-Text Transfer Protocol (HTTP) is the method used to transfer Web pages to your computer. 
8. With hypertext, a word or phrase can contain a link to another Web site. 
9. All Web pages are written in the hyper-text markup language (HTML), which works in conjunction with HTTP.

Comparison of CRT, LCD, Plasma, and OLED....Just Have a Look but not necessary to learn all

Comparison

[edit]CRT

Further information: Cathode ray tube

Pros

• High contrast ratio (over 15,000:1), excellent color and wide gamut, excellent black level
• No native resolution; the only current display technology capable of true multisyncing (displaying many different resolutions and refresh rates without the need for scaling).
• No input lag
• No ghosting and smearing artifacts during fast motion due to sub-millisecond response time, and impulse-based operation.
• Near zero color, saturation, contrast or brightness distortion
• Allows the use of light guns/pens
• Excellent viewing angle

Cons

• Large size and weight, especially for bigger screens (a 20-inch (51 cm) unit weighs about 50 lb (23 kg))
• Relatively high power consumption at high brightness and contrast levels and fast scan rates
• Generates a considerable amount of heat when running
• Geometric distortion caused by variable beam travel distances but almost no distortion in most high-end displays.
• Can suffer screen burn-in
• Produces noticeable flicker at low refresh rates although all recent CRT monitors have sufficiently fast refresh rates
• Hazardous to repair/service
• Color displays cannot be made in sizes smaller than 7 inches. Maximum size for direct-view displays is limited to about 40 inches due to practical and manufacturing restrictions (a CRT display of this size can weigh about 300 pounds), though the sizing can be increased with an array of separate displays, such as the original Jumbotron used at sports arenas.
• The glass envelopes contains toxic lead and barium as X-ray radiation shielding. The phosphors can also contain toxic elements such as cadmium. Many countries treat CRTs as toxic waste and prohibit their disposal in landfills or by incineration
• Purity and convergence, affected by the Earth's magnetic field, must be factory preset for operation in either the northern hemisphere, the southern hemisphere, or the equatorial area. Adjustment for use outside a preset region requires high technical skill, as well as safety precautions

LCD

Further information: LCD and LCD TV

Pros

• Very compact and light
• Low power consumption. On average, 50-70% less energy is consumed than CRT monitors.
• No geometric distortion.
• The possible ability to have little or no flicker depending on backlight technology.
• Usually no refresh-rate flicker, as the LCD panel itself is usually refreshed at 200 Hz or more, regardless of the source refresh rate.
• Is very thin compared to a CRT monitor, which allows the monitor to be placed farther back from the user, reducing close-focusing related eye-strain. Though the CRT's flickering can be emulated nonetheless in niche applications.
• Razor sharp image with no bleeding/smearing when used at native resolution.
• Not affected by screen burn-in, though an identical but less severe phenomenon known as image persistence is possible.
• Can be made in almost any size or shape.
• No theoretical resolution limit.
• Can be made to large sizes (more than 24 inches) lightly and relatively inexpensively.
• Unconstrained by geographical (hemispheric) location of device with respect to Earth's magnetic field.
• As an inherently digital device, the LCD can natively display digital data from a DVI or HDMI connection without requiring conversion to analog.

Cons

• Limited viewing angle, causing color, saturation, contrast and brightness to vary, even within the intended viewing angle, by variations in posture.
• Uneven backlighting in some (mostly older) monitors, causing brightness distortion, especially toward the edges.
• Black levels may appear unacceptably bright due to the fact that individual liquid crystals cannot completely block all light from passing through.
• Smearing and ghosting artifacts on moving objects caused by slow response times (>8 ms).
• As of 2012, most implementations of LCD backlighting use PWM to dim the display, which makes the screen flicker more acutely (this does not mean visibly) than a CRT monitor at 85 Hz refresh rate would (this is because the entire screen is strobing on and off rather than a CRT's phosphor sustained dot which continually scans across the display, leaving some part of the display always lit), causing severe eye-strain for some people. Unfortunately, many of these people don't know that their eye-strain is being caused by the invisible strobe effect of PWM. This problem is worse on many of the new LED backlit monitors, because the LEDs have a faster turn-on/turn-off time than a CCFL bulb.
• Only one native resolution. Displaying any other resolution either requires a video scaler, causing blurriness and jagged edges; or running the display at native resolution using 1:1 pixel mapping, causing the image either not to fill the screen (letterboxed display), or to run off the lower right edge of the screen.
• Fixed bit depth, many cheaper LCDs are only able to display 262,000 colors. 8-bit S-IPS panels can display 16 million colors and have significantly better black level, but are expensive and have slower response time.
• Input lag, because the LCD's A/D converter waits for each frame to be completely outputted before drawing it to the LCD panel. Also some modern LCDs do post-processing before displaying the image, which adds an additional lag. 
• Dead or stuck pixels may occur during manufacturing or through use.
• In a constant-on situation, thermalization may occur, in which part of the screen has overheated and looks discolored compared to the rest of the screen.
• Unacceptably slow response times in low temperature environments.
• Loss of contrast in high temperature environments.
• Not usually designed to allow easy replacement of the backlight.
• Poor display in direct sunlight. Transflective LCDs provide a large improvement by reflecting natural light, but have not yet been widely adopted.
• Cannot be used with light guns/pens.

[edit]Plasma

Further information: Plasma display

Pros

• High contrast ratios (10,000:1 static or greater) excellent color, and low black level.
• Millisecond response time
• Near zero color, saturation, contrast or brightness distortion. Excellent viewing angle.
• No geometric distortion
• Highly scalable, with less weight gain per increase in size (from less than 30 in (76 cm) wide to the world's largest at 150 in (3.8 m)).
• Unconstrained by geography with respect to Earth's magnetic field
• Variable power consumption (dimmer picture draws less power) though still higher than most LCD TVs in most situations.

Cons

• Large pixel pitch, meaning either low resolution or a large screen. As such, color plasma displays are only produced in sizes over 32 inches (81 cm) and 1080p displays are only available from sizes of 42" upwards.
• Image flicker due to being phosphor-based though modern plasma displays make this effect less noticeable.
• Glass screen can induce glare and reflections.
• High operating temperature and power consumption. LCDs consume less power.
• Input lag
• Relatively heavy weight
• Only has one native resolution. Displaying other resolutions requires a video scaler, which degrades image quality at lower resolutions.
• Can suffer image burn-in. This was a severe problem on early plasma displays, but newer models have incorporated methods to reduce the chance of accidental burn-in.
• Screen-door effects are noticeable on screen sizes smaller than 127 cm (50 in); the effect is more visible at shorter viewing distances
• Do not work as well at high altitudes due to pressure differential between the gases inside the screen and the air pressure at altitude. It may cause a buzzing noise. Manufacturers rate their screens to indicate the altitude parameters.
• For those who wish to listen to AM radio, or are amateur radio operators (hams) or shortwave listeners (SWL), the radio frequency interference (RFI) from these devices can be irritating or disabling.
• Relatively fragile; should only be transported, stored, and operated upright, as the glass screen can shatter under the display's own weight if not supported properly.
• Cannot be used with light guns/pens.
• Defective pixels such as dead pixels and stuck pixels may occur either during manufacturing (except stuck pixels) or through use.

[edit]OLED

Further information: Organic light-emitting diode

Pros

• Very high contrast ratio - above 1,000,000:1 static.
• Excellent viewing angle
• Very light weight
• Excellent black level
• No ghosting and smearing artifacts during fast motion due to sub-millisecond response time.
• Wide gamut and vivid colors because no backlight is used.
• Can be fabricated on flexible plastic substrates leading to the possibility being fabricated and of creating flexible video displays.
• No geographical constraints.

Cons

• Can suffer screen burn-in.
• Increased power consumption when displaying white color.
• Blue OLEDs degrades more rapidly than the materials that produce other colors.
• Poor readability in bright ambient light such as outdoors.
• Water can damage the organic materials of the display.
• Can be damaged by prolonged exposure to UV light.
• Difficult and expensive to manufacture at the present time.
• Organic materials used (as of 2011) are susceptible to decay over time, rendering the display unusable after some time.
• Defective pixels such as dead pixels and stuck pixels may occur either during manufacturing (except stuck pixels) or through use.
• Cannot be used with light guns/pens.
