The  Temple  Entry Authorisation Proclamation V of (1947-48) issued by the Maharaja of Cochin opened the  temples  in  that  State  to  all  castes.

The  Madras  Temple Entry Act of 1947 extended this reform to the Malabar area.


Kuttamkulam Struggle :1946

Kuttamkulam struggle  „Vazzhinadakkal Samaram‟; was started as a protest  against untouchability in  to the premise of the Kudalmanikyam  temple.

RENAISSANCE IN KERALA : SHORT NOTES

Hello Reader,

In this post we will discuss some interesting events in the History of Kerala. Each event is written in short note so that it will be easy to  prepare for various  Kerala P.S.C Examinations.

Image courtesy : The Internet :)

Ready.!!! Steady!! Go.!!!


Synod (പുരോഹിതസഭ) of  Diamper  (Udayamperur) : 1599

• The aim of this Synod  was to bring  the Christian  community  under  the  supremacy  of  the  Roman church.
•     Alexis De Menezes, the Archbishop  of Goa, presided the synod. 
•     The Synod scrutinized Syrian books and removed offending passages. They prohibited the use of many heretic books like “The Infancy of our Savior (The History of our Lady)”,” Book of John Barialdan “
•     The Cochin Diocese (ബിഷപ്പിന്റെ അധികാരപ്രദേശം) followed the Latin rite(അനുഷ്‌ഠാനം) and the old Syrian Diocese of Ankamali clung to the Syriac rite .

Revolt at the Coonan Cross : 1653

• Syrians were unhappy on Portugal king’s decision to  appoint  European Latin Bishops to the Syrian diocese of Ankamali. 
• In 1653  the Jacobite Patriarch of Babylon sent  a Bishop  named Ahatalla,  to Kerala, in  response  to  a  request  by  the  Syrians. The  Portuguese detained him  on  his  way at Mylapore .
• The excited Syrians assembled in thousands  in  front  of  an  ancient  Cross  in Mattancherri,  tied  a  lengthy  rope  on it  and holding on to it swore that they would never more obey the Latin Archbishop or the Jesuits. This is known in history as the “Oath of the Coonan Cross”. 
• This revolt  led to the emergence of two distinct sections among the Christians:  Pazhayakuru , the Romo-Syrians who continued to owe allegiance  to  the  Church  of  Rome, and  the Puthankuru,  the Jacobite Syrians who denounced the authority of the Pope.

.
Sri Narayana Dharma Paripalana Yogam :1903

•  1903  :The S.N.D.P. Yogam came into existence  under the inspiration of Sri Narayana Guru

Here we go.!!

 

 

 

1. Which of the following is not correct about HTTP cookies ?

a.A cookie is a piece of code that has a potential to compromise the security of an Internet user.

b. A cookie gains entry to the user's work area through an HTTP Header.

c. It has expiry date and time.

d. It can be used to track the browsing pattern of a user at a particular site.

a. Any personal information that you give to a Web site, including credit card information, will most likely be stored in a cookie unless you have turned off the cookie feature in your browser. 

b.  

c. The Expires directive in cookie  tells the browser the exact/absolute date and time  to delete the cookie

d  If the user requests a page of the site for first time the server creates a random string and sends it as a cookie back to the browser together with the requested page;this cookie will automatically be sent by the browser to the server every time a new page from the site is requested;the server stores the URL of the requested page, the date/time of the request, and the cookie in a log file. By analyzing the log file collected in the process it is possible to plot browsing pattern. 

Ans: a

2.If a binary tree has 20 leaves, then how many nodes will have two children nodes?

If there are n leaves, there will be (n-1) nodes having two child nodes. 

Answer is 20-1=19

 

3. In a typical server in which order the operations-  accept, bind, listen and recv - will be executing?
a)listen,bind,accept,recv
b)bind,listen,accept,recv
c)listen,accept,bind,recv
d)accept,listen,bind,recv

bind( )  :to associate the socket with a port on server machine

listen( ) :wait for incoming connections

accept( ):accept the connection request and returns new socket file descriptor

recv( ) : accepts the data from the client.

The order is as in (b):

 

4. Assume that for a certain processor, a read request takes 50 nanoseconds on a cache miss and 5 nanoseconds in a cache hit. Suppose while running a program, it was observed that 80% of the processor's read requests result in a cache hit. The average read access time in nanoseconds is :

Ans:  effective memory access time = (hit rate * cache access time) + (miss rate * access time for cache miss),

(50x20+5x80)/100=14 ns

 
5. Find the number of divisors for 2100?

To find the number of positive integral divisors, write the number as a product of prime numbers. Add one to exponent value of each prime number and multiply them together .

Read the method in detail here.

Given number 2100 can be represented as 2100=2*3*5*7*2*5=2^2 * 3 * 5^2* 7

Total number of divisors= (2+1)*(1+1)*(2+1)*(1+1)= 3*2*3*2= 36

a) Reflexive and symmetric but not transitive
b) Neither Reflexive nor symmetric but transitive
c) Symmetric but not reflexive, not transitive
d) Reflexive but not symmetric, not transitive

Ans c

#Given relation is symmetric for all integers. eg: 7R21  means 21R7

#Given relation cannot be reflexive as a and b should be distinct numbers.

#Given relation may not be transitive Eg: 7R21 and 21 R 3 are true but 7R3 is false.

10. In an unordered list of numbers find the complexity of an algorithm to search for an element which is neither maximum nor minimum.
a. Θ(n logn) 

b. Θ( n)
c. Θ(log n)
d. Θ(1)

Ans: d 

We only need to consider any 3 elements and compare them. So the number of comparisons is constants, that makes time complexity as Θ(1)

Let us take an array {10, 20, 15, 7, 90}. Output can be 10 or 15 or 20
Pick any three elements from given liar. Let the three elements be 10, 20 and 7.

22. A graph is self complementary if it is isomorphic to its complementary graph. For a self complementary graph of n vertices which of the following is correct?
a. n is a multiple of 4
b. n is odd
c. n is even
d. n is congruent to 0 mod 4 or 1 mod 4

23. Which of the following is correct?
a.  Code inspection is done after unit testing is completed.
b. Code walk through and Code inspection are synonymous.
c. Coding standards are evaluated during code inspection
d. Code walk through is done by an independent team.

Ans: a. 

Unit testing should be done before Code inspection. 

Code inspection and code walk through have many differences. For example,  Code inspection is formal, initiated by project team and planned one while walk through is informal, initiated by the author and unplanned.

Code Inspection is done to find and fix mistakes

Code walk throgh is done by the author only

24 Consider a simple check-pointing protocol and the following set of operations in the log. 

(start, T4); (write, T4, y, 2, 3); (start, T1); (commit, T4); (write, T1, z, 5, 7);

 (checkpoint);

 (start, T2); (write, T2, x, 1, 9); (commit, T2); (start, T3), (write, T3, z, 7, 2); 

If a crash happens now and the system tries to recover using both undo and redo operations, what are the contents of the undo list and the redo list?

(A) Undo: T3, T1; Redo: T2 

(B) Undo: T3, T1; Redo: T2, T4 

(C) Undo: none; Redo: T2, T4, T3, T1 

(D) Undo: T3, T1, T4; Redo: T2 

Ans: A

In recovery stage, we need not  take care of transactions committed before checkpoint. 

T2 is committed after checkpoint. Thus redo it.

T1 and T3 are not committed after checkpoint. Thus abort them by undoing

32. Consider a processor with byte-addressable memory. Assume that all registers, including Program Counter (PC) and Program Status Word (PSW), are of size 2 bytes. A stack in the main memory is implemented from memory location (0100)16 and it grows upward. The stack pointer (SP) points to the top element of the stack. The current value of SP is (016E) 16. The CALL instruction is of two words, the first word is the op-code and the second word is the starting address of the subroutine (one word = 2 bytes). The CALL instruction is implemented as follows:
• Store the current value of PC in the stack 

• Store the value of PSW register in the stack

 • Load the starting address of the subroutine m PC 

The content of PC just before the fetch of a CALL instruction is (5FAO) 16. After execution of the CALL instruction, the value of the stack pointer is

 (A) (016A) 16 (B) (016C)16 (C) (0170)16 (D) (0172)16 

Current value of SP: 016E

PC (2 bytes) will be stored in: 016F and 0170

PSW(2bytes) will be stored in: 0171 and 0172

So after execution of CALL instruction the value of stack pointer is 0172

55)  . A computer system implements a 40-bit virtual address, page size of 8 kilobytes, and a 128-entry translation look-aside buffer (TLB) organized into 32 sets each having four ways. Assume that the TLB tag does not store any process id. The minimum length of the TLB tag in bits is_________:

 

 Size of a page = 8KB = 2^13
Total number of bits needed to address a page frame = 40 – 13 =  27

If there are ‘n’ cache lines in a set, the cache placement is called n-way set associative. Since T.L.B is 4 way set associative and can hold total 128  page table entries, number of sets in cache = 2^7/4 = 2^5. 

So 5 bits are consumed to address a set.

Hence number of bits needed for tag= 27 -5 =22
