Generate the CRC codeword for the message x3+1 using the generator polynomial x3+x+1.
Consider the following partial Schedule S involving two transactions T1 and T2. Only the read and the write operations have been shown. The read operation on data item P is denoted by read(P) and the write operation on data item P is denoted by write(P) Time Instance Transaction-id T1 T2 1 read(A)   2 write(A)   3   read(C) 4   write(C) 5   read(B) 6   write(B) 7   read(A) 8   Commit 9 read(B)     Schedule S   Suppose that the transaction T1 fails immediately after time instance 9. Which one of the following statements is correct?
A linear Hamming code is used to map 4-bit messages to 7-bit codewords. The encoder mapping is linear. If the message 0001 is mapped to the codeword 0000111, and the message 0011 is mapped to the codeword 1100110, then the message 0010 is mapped to
Transient stability of the generator is dependent on (a) generator reactance; lower reactance decreases peak power and increases initial rotor angle. (b) how heavily the generator is loaded. (c) generator inertia; higher the inertia, slower the rate of the change of angle. (d) generator output during fault Which of the above is incorrect?
Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.
In CRC calculation if divisor is 1011, and dataword is 1001 what will be the CRC?
S1: Always remember that regular and frequent practice is essential if you are to learn to write well.
P: Even with the most famous writers, inspiration is rare.
Q: Writing is 99 percent hard work and one percent inspiration, so the sooner you get into the habit of writing, the better.
R: It is no good waiting until you have an inspiration before you write.
S: You learn to write by writing.
S6: If you keep your eyes and ears open, you will find plenty of things to write about around you to be able to discipline yourself to write.

Consider a Simple Checkpointing 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?
