ACK

In 4th semester, between yawns and sighs for a better career option, I managed to learn ARQs in Data communications. For those lucky people who don't know(and probably won't care) what an ARQ is, it stands for Automatic Repeat Request/Query.It is an error-control method for data transmission which uses acknowledgements and timeouts to achieve reliable data transmission over an unreliable link. The basics are pretty simple. You send a frame of data to the receiver, set a timer, wait for an acknowledgement from the receiver. If you receive the acknowledgement from the receiver before time out, it means that your frame has been delivered and the receiver is expecting the next frame. If the acknowledgement is not received, then the sender re sends the frame. There are several things that can go wrong(and will go wrong in all probability) and these exceptions are handled accordingly. There are several types of ARQs but let us not get into specifics. My focus here is on the acknowledgement.
What is a person's first instinct when he/she receives genuine appreciation? Is it surprise? Is it gratitude? I feel both of these. Somehow, I'm very vocal in appreciating someone and also acknowledging the fact that someone appreciates me. There are times when I genuinely mean something and wish good for another being and express it in all earnest, yet it goes unacknowledged. It just makes me wonder, are people that self assured that they can't even be thankful for the fact that someone recognises their worth? I am always surprised when people pay me a compliment or tell me how much I mean to them. I'm not such a great person in real life and listening to phrases pertaining to appreciation with respect to yours truly always makes me think about how phony people are. But then I feel guilty for being sceptical and petty and I respond with genuine thanks for realising that I aren't all that bad sometimes. Maybe I suffer from low self esteem(which many people have pointed out) or I am too dependent on others' approval and any that comes my way seems like a cascade of affection. But yet, even if a person is self assured and confident of his/her own worth, it's nice to acknowledge. Just a simple 'Thank you' will suffice most times.
P.S- I never thought I'd come to a stage where I'd start comparing information science and engineering to ANY thing related to my life. I have come to a stage where I use programming terms in day to day life and care about things like ready queues and scheduling algorithms. God help me!
P.P.S- If anyone ever pays a compliment regarding my hair, it is promptly followed by 'I know!'. So much for genuine acknowledgement.
