Here’s a quick difference between the two protocols:
|1 Full form
Transmission Control Protocol
|User Datagram Protocols
||The destination will receive the packets in the same order it was being sent.
||There will be no proper order/ arrangement of data.
|3 Success Rate:
||Data must be transmitted WITHOUT FAIL
||No guarantee that all data will be successfully transmitted. It is used where it is acceptable to lose some data points.
||UDP provides no guarantee for delivery and no protection from duplication.
||More overhead due to error-checking mechanisms.
||The simplicity of UDP reduces overhead from the protocol and can be adequate for some applications.
Connection is first established with recipient, only after that sent.
A computer may send UDP packets without first establishing a connection to a recipient.
|8 Real Time Example:
||TCP is mailing a letter with a return receipt at the post office, except that the post master will organise the letters in-order-of mailing and only deliver them in-order.
||UDP is mailing a letter at the post office without making extra care if all mails are received.
||Web, SSH, FTP, telnet, IMAP/POP, receiving mail,
||DNS, DHCP, Media streaming, Tunneling/VPN
|10 In short:
||TCP is for high-reliability data transmissions
||UDP is for low-overhead transmissions

All the best for your interviews or exams.
It sounds simple from the way it is being instructed but here’s what you need to be aware of.
What you need:
1. Proper network. You can re-attempt twice in case of failures, but not more than that.
2. Closed room, with no disturbance.
3. Use headphones with good sound, or put loudspeakers.
4. Vigilant ear, because the only key to cracking this is attention.
5. Note down Your AMCAT ID, PARSE KEY (given to you by your test centre), SVAR ID, TEST ID in a notepad.
You need to type these on your mobile’s keypad for verification.
6. A pen or pencil
(In my situation, I kept my laptop open.
I opened the email instructions in Gmail and placed it in front of me.
There was a pad to my hand’s reach and a pen in my right hand. My left hand was holding the phone.)
Duration: 18-20 minutes
Number of questions: Approximately 40-45
They’ll send you 12 sentences via email in prior which you need to recite at the time of your phone call.
After each beep you need to speak fast and with proper pronunciation within a span of merely 5 seconds.
The automated voice on the phone will recite ten sentences.
You need to repeat the sentence you hear.
You will only get one chance to hear a sentence.
If you listen attentively, you can deliver the same well.
In this section, you will hear a conversation followed by a set of questions based on it.
Scribble the points first. In my case, it was a conversation between a lady and a customer service regarding wrong shopping order.
Multiple choice questions followed by its options. Answer as per the instructions given.
You will hear sentences which might have a grammatical error. It will be followed by four options each being a part of the sentence itself. Identify the part which contains an error.
A topic of speech will be assigned to you and you are required to speak about it for 45 seconds.
Mine was ‘A busy market scene’.
All the best. Muster all your wisdom and crack it.
Learning good English isn’t much of a task if you do feel it is IMPORTANT to do so.
The problem is that everyone wants to shine like the sun, but you’ve forgotten to burn like one for that.
So, let me get to the point.
Here are the easiest and fastest steps (it’s up to you to simply roll down and return back to being the same old you or to execute it):
- Watch a lot of TV Shows: Anything from Crime shows to Sci-Fi or horror or detective. Those which involve a lot of informal conversations. And stay away from the subtitles once you start getting a grasp.
- Watch Rom-Com’s and Critically-Acclaimed-Award-Winning movies: If your choice of movies is limited to Marvel, DC, robot-breaking-movies or those of the same type, you haven’t had a real taste of Hollywood. Learn from the Urban conversations in reality-based movies.
- Listen to English music: If your choice is limited to Selena Gomez, Enrique Iglesias, Jay Sean and Pitbull (Indian favorites), you have very BAD TASTE in music alone, let go of English-learning. Google for best lyrics, and imbibe good words from the best songs. Feel the lyrics. It will add to your persona. It will make you wiser.
- Read a lot of magazines: Entertainment, Fashion, Sports, Technology : anything! Keep a highlighter-pen and mark words which seem new to you. Try to use those words in the contexts of your real life. Practice makes man perfect!
- Read essays written by famous political figures or debaters: Guaranteed this will help you in almost everything you’re working on.
- And the last and obvious one. Develop a habit of reading novels : You can choose from any genre. If you’re looking for Indian authors, I’d recommend Anuja Chauhan for her witty narration and exceptionally good vocabulary. With foreign writers, there’s a lot you can choose from.
All the best 🙂
And tell me if this works for you.
