iOS vs Android

Over the past decade, Smart-phones have only increased in value and assisted thousands of professionals from important projects to the most basic tasks. The permeating value of smart-phones and their day-to-day applications cannot be ignored as they have great influence on daily routines and business matters.

Today the most common operating system technologies used in smart-phones are iOS (iPhone operating system) and Android operating system. Well the choices between apple iOS and Android depend upon various factors that user value. Let's measure both of them with features which users care about the most.

Ease of Use

  • In terms of ease, most of the users will agree that iPhone is the first choice. Android has come a long way and has improved a lot but with respect to ease of use perspective iPhone takes the cake. Android phones consist of a lot of buttons and a home screens too.

Candidness

  • With respect to openness, Android takes preference as it is open source, and most users prefer openness in terms of what can be done with the smart-phone. Android market offer variety of apps, majority of them are free as well.

Battery Consumption

  • On the basis of battery timing, iPhone is what you actually want. In fact Android devices support a lot of features that is why the battery life is low. Well Android phones vary in terms of battery timing but overall they have less battery time with compared with iPhone.

Keyboard Optimization

  • The keyboard of iOS software is appreciably better than the Android's keyboard, but in terms of a system-wide search, both iPhone and Android search out more or less same things. Android devices just cannot search emails

Sync Features

  • The synchronization feature of iPhones is traditional one as it requires users to plug in connect to iTunes, while this should be done wirelessly. Android phones or Android tablets have excellent syncing feature supported by Google, and it continues to work even if you old smart-phone has been lost. But iPhone's voice text feature is superb and works much better than any of its counterparts.

  • At last but not the least, Android operating system is better than iPhone because it can convert your device into a Wi-Fi hot spot which can actually provide Wi-Fi connection up to 7 buddies.

Conclusion

It is really hard to decide which is better iPhone or Android. An important indicator for choice between then is Apps: The apps make the phone, after all! Though number of apps available at apple store is tremendously high than Anrdoid apps but a lot of them are crap too. 

Earlier I explained functions of TCP/IPadvantages of UDP over TCP, and advantages of TCP over UDP. Find here the real life uses of both TCP and UDP.

Example Uses of TCP Protocol:

  • Internet (HTTP)
  • Secure Shell (SSH)
  • Email (SMTP/IMAP/POP)
  • File transfer (FTP)
  • Internet banking
  • Remote access to network devices
  • SMS

Uses of UDP protocol:

  • Audio and video streaming
  • Voice over IP (VoIP)
  • Online gaming
  • Trivial File Transfer Protocol (TFTP)
  • Domain Name System (DNS)
  • Radio (AM)
  • WiFi
  • Video conference

These were the real life uses of UDP and TCP. There may be more uses of TCP and UDP, but with the examples above, I hope you now have understood the role of TCP and UDP well.

Technology of 3D TV

The technology is moving at a very fast pace and changing its façade day by the day, getting revolutionized day by day in service of mankind. Hence when it comes to the entertainment aspects, the pace of technology is exponentially high due to the lust of mankind to be entertained, and therefore the advancement in digital displays has seen tremendous pace in the past decades in the quest of jumping to the higher step of possibilities and perfection. By all means the present day 3D TV is the result of the aforesaid phenomenon. The humans have been able to witness the revolution from the 2 dimensional displays to 3 dimensional. Also the research is underway which has partially been successful where 3D display can be enjoyed without glasses and wide variety of angles, though until now 3D TV technology without glasses are still a dream.

How 3D TV Works ?

The principle behind the 3D tv technology is based on a biological phenomenon pertaining to eyes known as the parallax. Human eyes are placed at a distance on the face and they receive different visuals and the inherent distance between the eyes is covered by the slight overlap though different images received by the two eyes due to difference in angle of reception of the two eyes. Hence the human brain then establishes the link between the images received by the two eyes, joins them into one single image.

This is a natural phenomenon, but normal tv was a two dimensional display and converting that two dimensional display into an artificial 3d display needed a trick to be played with the mother nature and that trick was to present a bit different image to each of both human eyes  and that is achieved by the use of 3d TV glasses, where the signals of the images are displayed in all directions and the 3d TV glasses thus play their part by presenting only the wanted signals to each eye, and eventually a 3d image is perceived in the brain. This kind of 3d TV technology is known as the passive 3d TV technology. This is how 3d TV works.

3d Images Without Glasses

On the other hand in order to achieve the 3d display without glasses, the glasses free 3d TV technology is being worked upon where control of the light will be directed from each pixel of display, in order to achieve different patterns of light to be received by each eye and ultimately the humans can see an active 3d TV.

Advantages of TCP over UDP

I earlier explained advantages of UDP over TCP, find out below the advantages of TCP over UDP.

1. Data packets which get lost during transmission are sent again, thus ensuring complete information is sent.

2. TCP ensures no duplicate data is sent, hence also saves bandwidth.

3. Data is sent in the same order in which it is sent.

4. TCP breaks up data into Packets automatically for you.

Recommended Use of TCP

TCP is best used for sending emails (IMPAP/POP/SMTP) where every letter and word of the message must be sent and received. TCP is also important to use for FTP where file downloading and uploading requires every information of the file to be completely sent/received. In a secure connection, like SSH, TCP is also necessary where acknowledgement of sensitive information being fully sent and received is required.

These were the advantages of TCP over UDP. Also read:
