How BITs and BYTEs works?

BIT stands  for Binary Digits. To understand it, lets first understand how decimal number works. Decimal numbers are combination of few digits. A digit is a single place that can hold numerical values between 0 and 9.
For example in the four digit number 3427, 7 fills the "1s place", while 2 fills the "10s place", 4 fills the "100s place and 3 fills the "1000s place". So we can express the number 3427 as :
(3*1000)+(4*100)+(2*10)+(7*1)=3000+400+20+1=3427

We can also express it in the powers of 10 as 
(3*10^3)+(4*10^2)+(2*10^1)+(7*10^0)=3000+400+20+1=3427:
Decimal number are therefore " base-10 number systems".

Computer operates on "base-2 number system" and it is also known as "binary number system" as it has only two possible values "0 and 1" unlike decimal numbers having values "0 till 9". Each is called as bits.

For the 1110 binary number we can find the corresponding decimal number in the way we did for 3427 as:
(1*2^3)+(1*2^2)+(1*2^1)+(0*2^0)=8+4+2+0=14.

Align post title to center

I did not think about centering the title of the post till I created by forum for my blog. The title "Forum" at the left top left side of the page was making my forum look so artificial. So I actually wanted to center the title of that page and I however came to know that centering the post title will also center the page title. I think it gives better looks to my blog. It is very easy to do.

Lost Generation by jonathan reed

Lost Generation is a poem written by Jonathan Reed, originally appearing as an entrant in AARP's U@50 Video Contest. When first read, the poem seems to be a pessimistic monologue of the current generation, an echo of sentiments often found when looking at news reports and articles. The last line of the poem, and the presentation of the poem in the original video, suggests reading it in reverse. When read backwards the poem paints a polarizing view, showing a brighter interpretation of the future. The poem follows a read-and-reverse pattern. Jonathan Reed is a student at Georgia State University in Atlanta, Georgia. He is in his early twenties.

Ctrl+Alt+Del to log on

I remember, in many of the computer labs, we are  required to press Ctrl+Alt+Del to log on. What could be the reason? Why do we need to do that? Can we do the same for our own system?

The reason is simple. Requiring to press Ctrl+Alt+Del provides an extra layer of security by implementing  a bit of 'human touch'.

Dirty jokes

I know many a times, many people hate to stick on the schedule of Monday. This is just because that everybody after a weekend's enjoyment and perfect repose feels drowsy n sleepy. I hate Monday too. Moreover, I do miss Monday's classes sometimes. Today also I missed morning classes just by not getting up early. It is absolutely not easy to get in time on Monday. I did not get anything important to do so I have just collected following jokes  from the Google to keep myself away from drowsiness.
