I FOUND HIM

Friendship doubles our joy and divides our grief.
Swedish proverb 


I saw their pictures. (him & his girl friend) On my Facebook wall, i always see his posts, status etc.
I was happy for him.


After some months, i saw him online & buzzed him. He replied. That was the first time we chatted.
He responded cool and just like my kinda person. We talked a bit about ourselves and exchanged phone numbers.




A week or two passed and I didn't call him or text him. Finally, he broke the ice(he sent me a message)
& i was asleep. When i woke up, i saw his missed call, I was astonished.
WOW i screamed.
I replied his text & thats how it started with us.

INFORMATION TECHNOLOGY

Information technology (IT) is "the study, design, development, application, implementation, support or management of computer-based information systems, particularly software applications and computer hardware", according to the Information Technology Association of America (ITAA).IT deals with the use of electroniccomputers and computer software to securely convert, store,protect, process, transmit, input, output, and retrieve information.


Today, the term information has ballooned to encompass many aspects of computing and technology, and the term has become very recognizable. IT professionals perform a variety of functions (IT Disciplines/Competencies) that range from installing applications to designing complex computer networks and information databases. A few of the duties that IT professionals perform may include data management, networking, engineering computer hardware, database and software design, as well as management and administration of entire systems. Information technology is starting to spread farther than the conventional personal computer and network technology, and more into integrations of other technologies such as the use of cell phones, televisions, automobiles, and more, which is increasing the demand for such jobs.
