# CS101 Topic-002. Breadth first learning Discussion

• Bit is a computer abrivation or mathematical abrivation???

Bit is not an abbreviation. It is the smallest unit of measurement used to quantify computer data. It contains a single binary value of 0 or 1.

• Asslam o Alaikum Sir, Respectfully Sir Patteren of Bits sai se smj nai aya that how bits convert 2-4 and 4-8 an so on it is main confusion

Each bit can represent either 0 or 1, so we have two unique patterns per bit. So, E.g. if bit n=1 implies 21= 2 patterns (0 or 1), if n=2 implies 22 = 4 patterns (00, 01, 10, 11). And similarly so on. So, Number of possible patterns of N bits = 2N.

• What is difference between intitle, inURL and intext? I think there is no difference between them

Dear Student,
The “inurl” operator finds all those web pages which contains the mentioned query in the url of the web pages.

The “intitle” operator will give us only those web pages in which the searched term appears in the title of the web pages.

With the “intext” operator we can search anywhere in the body of the document.
It is advised to listen to the related topic carefully to understand their working in detail.

• Slam sir Icannot understand the bits pattern

WaAlaikum Assalam

Dear student,

In bits patterns, it is told that 1 bit can form 2 patterns, 2 bits can form 4 patterns, 3 bits can form 8 patterns and so on. It can be calculated as:

2^1 = 2

2^2 = 4

2^3 = 8

2^4 = 16

For two-bit pattern, you have 0000 and 0001

For three-bit pattern, you have 0000, 0001 and 0010

And so on…

In bit pattern, you can represent like:

 8 7 6 5 4 3 2 1 0 1000 0111 0110 0101 0100 0011 0010 0001 0000

For characters like ABC, codes are given in ASCII table. You can calculate the binary number for any character according to the given code.

• What is difference between Breath first learning and Depth first learning?

In depth first learning we drill very deeply into one subject before moving on to the next, without any initial explanation as to why we’re learning what we’re learning or how the entire puzzle fits together.

Breadth-first learning is progressively more and more detailed overviews are given, covering all topics within a field concurrently to better understand the overall picture and how what you are learning in one subfield applies to the others.

• Assalam o alikum! Sir how we put example like i search jaguar car in Google. Google show result we must put all information that google give us?

Dear student,

If your query is about the search queries, then yes you can put this search query in way you want. Here are some tips and also these are in your lectures as well.

inurl operator finds all those web pages which contains the mentioned query in the url (website address) of the web pages. For example, if we try the following query:
inurl:2018 “Cyberian”
This will give us all those web pages in which 2018 is written and the phrase “Cyberian” is written in the URL.

Intext searches the search string anywhere in the body of the document, for example
intext:“CS101 Assignment Cyberian” this will give all those pages in which the whole phrase is present as it is in the body text of the page.

Proximity Search Suppose we are interested to search two words: Education and Cyberian But both words should be collocated on the web page within the margin of three words.
It means the words should not be at a distance of 3 words from each other. To achieve this, we can use the operator around.
education AROUND(3) “Cyberian” This query will give all those web pages on which both words are available within the margin of three words

• how A=67 B=66 a=97 and space =32.i didn`t get the concept behind this slide. please elaborate.

ASCII code has been discussed in this topic. ASCII stands for American Standard Code for Information Interchange. ASCII is a code for representing English characters as numbers, with each letter assigned a number from 0 to 127. For example, the ASCII code for uppercase “M” is 77, the letter “A” is Character 65, B=66 and a=97. Most computers use ASCII codes to represent text, which makes it possible to transfer data from one computer to another.
