397What is the main difference between traps and interrupts?
398A trap is an exception in a user process. It's caused by division by zero or invalid memory access. It's also the usual way to invoke a kernel routine (a system call) because those run with a higher priority than user code. Handling is synchronous (so the user code is suspended and continues afterwards). In a sense they are "active" - most of the time, the code expects the trap to happen and relies on this fact.
399A trap is an exception that is reported immediately following the execution of the trapping instruction. Traps allow execution of a program or task to be continued without loss of program continuity. The return address for the trap handler points to the instruction to be executed after the trapping instruction.
400
401
402An interrupt is something generated by the hardware (devices like the hard disk, graphics card, I/O ports, etc). These are asynchronous (i.e. they don't happen at predictable places in the user code) or "passive" since the interrupt handler has to wait for them to happen eventually.
403Interrupts occur at random times during the execution of a program, in response to signals from hardware. System hardware uses interrupts to handle events external to the processor, such as requests to service peripheral devices. Software can also generate interrupts by executing the INT n instruction.

537Buffering is useful because
538a data buffer (or just buffer) is a region of a physical memory storage used to temporarily store data while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers). However, a buffer may be used when moving data between processes within a computer. This is comparable to buffers in telecommunication. A majority of buffers are implemented in software, which typically use the faster RAM to store temporary data, due to the much faster access time compared with hard disk drives. Buffers are typically used when there is a difference between the rate at which data is received and the rate at which it can be processed, or in the case that these rates are variable

579       ____________is the first schema to be designed when you are developing a DBMS
580The term "schema" refers to the organization of data as a blueprint of how the database is constructed (divided into database tables in the case of relational databases). The formal definition of a databaseschema is a set of formulas (sentences) called integrity constraints imposed on a database.[citation needed] These integrity constraints ensure compatibility between parts of the schema. All constraints are expressible in the same language. A database can be considered a structure in realization of the database language.[1] The states of a created conceptual schema are transformed into an explicit mapping, the database schema. This describes how real-world entities are modeled in the database.

585Suppose that everyone in a group of N people wants to communicate secretly with N-1 others using symmetric key cryptographic system. The communication between any two persons should not be decodable by the others in the group. The number of keys required in the system as a whole to satisfy the confidentiality requirement is
586(A) 2N
587(B) N(N – 1)
588(C) N(N – 1)/2
589(D) (N – 1)2
590Answer: (C) 
591
592Explanation: In Symmetric Key Cryptography, access of key is with both the parties. It implies every person needs to communicate N-1 other users using different keys i.e 1+2+3…N-2+N-1
593This is like number of edges needed in a complete graph with N vertices is N(N-1)/2.

Minterm groups must be rectangular and must have an area that is a power of two (i.e., 1, 2, 4, 8…). Minterm rectangles should be as large as possible without containing any 0s. Groups may overlap in order to make each one larger.
599
600The grid is toroidally connected, which means that rectangular groups can wrap across the edges .

658SQl allows duplicates tuples in relations, and correspondingly defines the multiplicity of tuples in the result of joins. Which one of the following queries always gives the same answer as the nested query shown below:
659select * from R where a in (select S.a from S)
660(A) Select R.* from R, S where R.a=S.a
661(B) Select distinct R.* from R, S where R.a=S.a
662(C) Select R.* from R, (select distinct a from S) as S1 where R.a=S1.a
663(D) Select R.* from R, S where R.a = S.a and is unique R
664Multiplicity of duplicate tuples will be distributed when there is a match between R.a and S.a; and for that match, S.a's value is repeated in each cases except the third case.
665So, the correct answer is option (C).

668The main difference between JK and RS flip-flop is that
669The JK Flipflop is a variation or an improvement of the SR Flipflop.
670
671The disadvantage of the SR flip-flop is that both inputs shouldn't be HIGH when the clock is triggered. This is considered an invalid input condition, and the resulting output isn't predictable if this condition occurs.
672
673The main difference between a JK flip-flop and an SR flip-flop is that in the JK flip-flop, both inputs can be HIGH. When both the J and K inputs are HIGH, the Q output is toggled, which means that the output alternates between HIGH and LOW. Thereby the invalid condition which occurs in the SR flipflop is eliminated.----------------------------
674
675The functional difference between SR flip-flop and JK flip-flop is that
676[A].	JK flip-flop is faster than SR flip-flop
677[B].	JK flip-flop has a feed back path

744Given the following schema:employees(emp-id, first-name, last-name, hire-date,dept-id, salary)departments(dept-id, dept-name, manager-id, location-id)
745You want to display the last names and hire dates of all latest hires in their respective departments in the location ID 1700. You issue the following query:SQL>SELECT last-name, hire-date
746FROM employees
747WHERE (dept-id, hire-date) IN
748(SELECT dept-id, MAX(hire-date)
749FROM employees JOIN departments USING(dept-id)
750WHERE location-id = 1700
751GROUP BY dept-id);
752What is the outcome?
753
754What is the outcome?
755A)	It executes but does not give the correct result
756B)	It executes and gives the correct result.
757C)	It generates an error because of pairwise comparison.
758D)	It generates an error because of the GROUP BY clause cannot be used with table joins in a sub-query.
759
760SELECT dept-id, MAX(hire-date) 
761    FROM employees JOIN departments USING(dept-id) 
762    WHERE location-id =1700 
763    GROUP BY dept-id
764this inner query will give the max hire date of each department whose location_id =1700 
765
766and outer query will give the last name and hire-date of all those employees who joined on max hire date.  
767answer should come to (B)  no errors 
768And we can use group by and where together, who said we can not :( 
769
770Example: create table departments(dept_id number, dept_name varchar2(25), location_id number); 
771Query: select d1.dept_name,max(d1.location_id) 
772from departments d1, departments d2 
773where  d1.dept_name = d2.dept_name 
774and d1.dept_name='AA' 
775group by d1.dept_name;

795
796
797Is it choice c? If so how do I show that a is logically equivalent to b and d ?
798Re: Which one of following Boolean expressions is not logically equivalent to all of
799Yes, it's c. You can show that (a) = (b) as follows. Note that a + a'b = (a + a')(a + b) (by distributivity of disjunction over conjunction) = 1(a + b) = a + b. Of course, similarly a' + ab = a' + b. Using this trick and factoring out w, we get
800
801xy' + z' + xyz + y'z =
802xy' + xyz + z' + y' =
803xyz + z' + y' (since xy' + y' = (x + 1)y' = 1y' = y') =
804xy + z' + y' =
805x + z' + y'
806
807The fact that (b) = (d) is trivial. Nonequivalence of (c) is best verified by finding truth values where the expressions differ. Of course, equivalence can also be checked using truth tables.

813[A].	8
814[B].	10
815[C].	14	 
816
817[D].	16
818Answer: Option C
819The size of the memory is N*M
820
821where N is the address lines and M is word length
822no of registers/memory location required is 2^N
823
824Given memory capacity is 16k 
825thus 2^N=16K
8261K=1024 memory locations
827thus16k=16*1024=16384
828now 2^N=16384
829After factorising 16384 by 2 we ll get N AS 14
830SO ADDRESS LINE REGUIRED IS 14.
831
8322^4= 2 x 2 x 2 x 2 = 16.
8332^10= 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 1024.
8342 to the power of 4 = 16.
8352 to the power of 10 = 1024.
836So: add the two power 4 + 10 = 14.

942For a C program accessing X[i][j][k], the following intermediate code is generated by a compiler. Assume that the size of an integer is 32 bits and the size of a character is 8 bits.
943t0 = i * 1024
944t1 = j * 32
945t2 = k * 4
946t3 = t1 + t0
947t4 = t3 + t2
948t5 = X[t4]
949
950Which one of the following statements about the source code for the C program is CORRECT?
951(A) X is declared as “int X[32][32][8]”.
952(B) X is declared as “int X[4][1024][32]”.
953(C) X is declared as “char X[4][32][8]”.
954(D) X is declared as “char X[32][16][2]”.
955
956
957Answer: (A) 
958
959Explanation: The final expression can be simplified in form ofi, j and k by following the intermediate code steps in reverse order
960t5 = X[t4]
961   = X[t3 + t2]
962   = X[t1 + t0 + t2]
963   = X[i*1024 + j*32 + k*4]
964   = X + i*1024 + j*32 + k*4 
965Since k is multiplied by 4, the array must be an int array.
966We are left with 2 choices (A and B) among the 4 given choices.
967X[i][j][k]’th element in one dimensional array is equivalent to
968X[i*M*L + j*L + k]’th element in one dimensional array
969(Note that multi-dimensional arrays are stored in row major order in C).
970So we get following equations
971j*L*4 = j*32, we get L = 8 (4 is the sizeof(int))
972i*1024 = i*M*L*4, we get M = 1024/32 = 32
973Therefore option A is the only correct option as M and L are 32 and 8 respectively
974only in option A.

1058A computer system implements 8 kilobyte pages and a +32-bit physical address space. Each page table entry contains a valid bit, a dirty bit, three permission bits, and the translation. If the maximum size of the page table of a process is 24 megabytes, the length of the virtual address supported by the system is _________ bits.
1059Ans: 36
1060Explanation
1061Max size of virtual address can be calculated by 
1062calculating maximum number of page table entries.
1063
1064Maximum Number of page table entries can be calculated 
1065using given maximum page table size and size of a page 
1066table entry.
1067
1068Given maximum page table size = 24 MB
1069
1070Let us calculate size of a page table entry.
1071
1072A page table entry has following number of bits.
10731 (valid bit) + 
10741 (dirty bit) + 
10753 (permission bits) + 
1076x bits to store physical address space of a page.
1077
1078Value of x = (Total bits in physical address) - 
1079             (Total bits for addressing within a page)
1080Since size of a page is 8 kilobytes, total bits needed within
1081a page is 13.
1082So value of x = 32 - 13 = 19
1083
1084Putting value of x, we get size of a page table entry =
1085                                   1 + 1 + 3  + 19 = 24bits.
1086
1087Number of page table entries 
1088           = (Page Table Size) / (An entry size)
1089           =  (24 megabytes / 24 bits)                             
1090           =  223
1091
1092Vrtual address Size 
1093             = (Number of page table entries) * (Page Size)
1094             =  223 * 8 kilobits
1095             = 236  
1096Therefore, length of virtual address space = 36
1097
1098

1124Three concurrent processes X, Y, and Z execute three different code segments that access and update certain shared variables. Process X executes the P operation (i.e., wait) on semaphores a, b and c; Process Y executes the P operation on semaphores b, c and d; Process Z executes the P operation on semaphores c, d, and a before entering the respective code segments. After completing the execution of its code segment, each process invokes the V operation (i.e., signal) on its three semaphores. All semaphores are binary semaphores initialized to one. Which one of the following represents a deadlock-free order of invoking the P operations by the processes?

1132Consider a join (relation algebra operation) between relations r(R)and s(S) using the nested loop method. There are 3 buffers each of size equal to disk block size, out of which one buffer is reserved for intermediate results. Assuming size(r(R))
1133Ans: relation r(R)r(R) is in the outer loop.
1134Explanation:
1135A join between r(R) and s (S) using nested loop method will be as follows.
1136For each tuple r in R do
1137For each tuple s in S do
1138If r and s satisfy the join condition then output the tuple <r,s>
1139This algorithm will involve Nr*Bs+Br block transfers and Nr+Br seeks, where Br and Bs are
1140number of blocks in relations R and S respectively and Nr is number of tuple in relation R.
1141Now to have less block accesses, Nr should be less and it is already given that |R|<|S|. Relation
1142r(R) should be in the outer loop to have fewer number of disk block accesses.

1146Consider the following C code segment:

1150{ static int a = 1; /* Line 1 */
1151prtFun( );
1152a + = 1;
1153prtFun( )
1154printf(?\n %d %d ?, a, b);
1155}
1156void prtFun(void)
1157{ static int a=2; /* Line 2 */
1158int b=1;
1159a+=++b;
1160printf(?\n %d %d ?, a, b);
1161}
1162What output will be generated by the given code segment?
1163Ans:
11644 2
11656 2
11662 0
1167Explanation:
1168‘a’ and ‘b’ are global variable. prtFun() also has ‘a’ and ‘b’ as local variables. The local variables hide the globals (See Scope rules in C). When prtFun() is called first time, the local ‘b’ becomes 2 and local ‘a’ becomes 4.
1169When prtFun() is called second time, same instance of local static ‘a’ is used and a new instance of ‘b’ is created because ‘a’ is static and ‘b’ is non-static. So ‘b’ becomes 2 again and ‘a’ becomes 6.
1170main() also has its own local static variable named ‘a’ that hides the global ‘a’ in main. The printf() statement in main() accesses the local ‘a’ and prints its value. The same printf() statement accesses the global ‘b’ as there is no local variable named ‘b’ in main. Also, the defaut value of static and global int variables is 0. That is why the printf statement in main() prints 0 as value of b.

1173Suppose a disk has 201 cylinders, numbered from 0 to 200. At some time the disk arm is at cylinder
1174100, and there is a queue of disk access requests for cylinders 30, 85, 90, 100, 105, 110, 135 and
1175145. If Shortest-Seek Time First (SSTF) is being used for scheduling the disk access, the request for
1176cylinder 90 is serviced after servicing ____________ number of requests.
1177Ans: 
1178 In Shortest-Seek-First algorithm, request closest to the current position of the disk arm and head is handled first.
1179In this question, the arm is currently at cylinder number 100. Now the requests come in the queue order for cylinder numbers 30, 85, 90, 100, 105, 110, 135 and 145.
1180The disk will service that request first whose cylinder number is closest to its arm. Hence 1st serviced request is for cylinder no 100 ( as the arm is itself pointing to it ), then 105, then 110, and then the arm comes to service request for cylinder 90. Hence before servicing request for cylinder 90, the disk would had serviced 3 requests.
1181Hence answer is 3.

1216}
1217Return 0:
1218}
1219The number of times printf statement is executed is ________.
1220Ans : 10
1221Explanation:
1222j = (((2 * 3) / 4) + (2.0 / 5) ) + (8/5); //As associativity of +,* and / are from left to right and + has less precedence than * and /.
1223j = ((6/4) + 0.4) + 1); //2.0 is double value and hence 5 is implicitly typecast to double and we get 0.4. But 8 and 5 are integers and hence 8/5 gives 1 and not 1.6
1224j = (1 + 0.4) + 1; // 6/4 also gives 1 as both are integers
1225j = 1.4 + 1; //1 + 0.4 gives 1.4 as 1 will be implicitly typecast to 1.4
1226j = 2.4; // since j is integer when we assign 2.4 to it, it will be implicitly typecast to int.
1227So, j = 2;
1228k -= --j;
1229This makes j = 1 and k = -1.
1230The variables j and k have values 1 and -1 respectively before the for loop. Inside the for loop, the variable i is initialized to 0 and the loop runs from 0 to 4.

1381What is the return value of f(p,p) if the value of p is initialized to 5 before the call? Note
1382that the first parameter is passed by reference, whereas the second parameter is passed by value.
1383int f (int &x, int c) {
1384c=c-1;
1385if (c==0) return 1;
1386x=x+1;
1387return f (x,c)*x;}
1388Ans: 
13896561
1390Since c is passed by value and x is passed by reference, all functions will have same copy of x, but different copies of c.
1391f(5, 5) = f(x, 4)*x = f(x, 3)*x*x = f(x, 2)*x*x*x = f(x, 1)*x*x*x*x = 1*x*x*x*x = x^4
1392Since x is incremented in every function call, it becomes 9 after f(x, 2) call. So the value of expression x^4 becomes 9^4 which is 6561.

1400Ans: 
140116 blocks and sets with 4 blocks each means there are 4 sets. So, the lower 2 bits are used for getting a set. And 4 way associative means in a set only the last 4 cache accesses can be stored. 
14020, 255, 1, 4, 3, 8, 133, 159, 216, 129, 63, 8, 48, 32, 73, 92, 155

14040, 3, 1, 0, 3, 0, 1, 3, 0, 1, 3, 0, 0, 0, 1, 0, 3
1405Now for each of 0..3, the last 4 accesses will be in cache. So, {92, 32, 48, 8}, {155, 63, 159, 3}, {73, 129, 133, 1} and {} will be in cache. So, the missing element from choice is 216.

1565Which of the following are sufficient conditions for deadlock?        
1566Ans -       
15671.	mutual exclusion
1568The resources involved must be unshareable; otherwise, the processes would not be prevented from using the resource when necessary.
15692.	hold and wait or partial allocation
1570The processes must hold the resources they have already been allocated while waiting for other (requested) resources. If the process had to release its resources when a new resource or resources were requested, deadlock could not occur because the process would not prevent others from using resources that it controlled.
15713.	no pre-emption
1572The processes must not have resources taken away while that resource is being used. Otherwise, deadlock could not occur since the operating system could simply take enough resources from running processes to enable any process to finish.
15734.	resource waiting or circular wait

2034If a disk has a seek time of 20ms, rotates 20 revolutions per second, has 100 words per block, and each track has capacity of 300 words. Then the total time required to access one block is 
2035
2036Time taken to access one block = seek time + rotational delay + block transfer time
2037Seek time = 20 ms (given)
2038Rotational delay = on an average taken to be the time to rotate by half = 1/2 X time for 1 rotati X 1/20 sec s = 25 ms
2039Block Transfer time = block size / transfer rate = 100 / transfer rate
2040Now, transfer rate = Track capacity / rotation rate = 300 / ( 1/ 20) = 6000 word per sec = 6 word per ms
2041Block Transfer time = block size / transfer rate = 100 / 6 ~ 16.67 ms per blockTime taken to access one block = seek time + rotational delay + block transfer time= 20 + 25 + 16.67 = 61.67 ms

2048Station A uses 32 byte packets to transmit messages to Station B using a sliding window protocol. The round trip delay between A and B is 80 milliseconds and the bottleneck bankwidth on the path between aA and B is 128 kbps. What is the optimal window size that A should use ? 
2049Round Trip propagation delay = 80ms 
2050Frame size = 32*8 bits
2051Bandwidth = 128kbps
2052Transmission Time = 32*8/(128) ms = 2 ms

2156The address of a class B host is to be split into subnets with a 6-bit subnet number. What is the maximum number of subnets and the maximum number of hosts in each subnet? 
2157Maximum number of subnets = 2^6-2 =62. 
2158Note that 2 is subtracted from 2^6. The RFC 950 specification reserves the subnet values consisting of all zeros (see above) and all ones (broadcast), reducing the number of available subnets by two.
2159Maximum number of hosts is 2^10-2 = 1022. 
21602 is subtracted for Number of hosts is also. The address with all bits as 1 is reserved as broadcast address and address with all host id bits as 0 is used as network address of subnet.
2161In general, the number of addresses usable for addressing specific hosts in each network is always 2^N – 2 where N is the number of bits for host id.

6706A 4-way set-associative cache memory unit with a capacity of 16 KB is built using a block size of 8 words. The word length is 32 bits. The size of the physical address space is 4 GB. The number of bits for the TAG field is
6707Number of sets = cache size / sizeof a set 
6708
6709Size of a set = blocksize * no. of blocks in a set  
6710= 8 words * 4 (4-way set-associative) 
6711= 8*4*4 (since a word is 32 bits = 4 bytes) 
6712= 128 bytes. 
6713
6714So, number of sets = 16 KB / (128 B) = 128
6715Now, we can divide the physical address space equally between these 128 sets. So, the number of bytes each set can access 
6716= 4 GB / 128 
6717= 32 MB 
6718= 32/4 = 8 M words = 1 M blocks. (220 blocks) 
6719
6720So, we need 20 tag bits to identify these 220 blocks.

7172In an Ethernet local area network, which one of the following statements isTRUE?
7173 (A) A station stops to sense the channel once it starts transmitting a frame.
7174(B) The purpose of the jamming signal is to pad the frames that are smaller than the minimum frame size.
7175(C) A station continues to transmit the packet even after the collision is detected.
7176(D) The exponential backoff mechanism reduces the probability of collision on retransmissions
7177
7178Answer: (D)
7179Explanation:
7180Now considering the Ethernet protocol we will discuss all the options one by one
7181
7182(A) This option is false as in Ethernet the station is not required to stop to sense for the channel prior frame transmission.
7183(B) A signal is jammed to inform all the other devices or stations about collision that has occurred so that further data transmission is stopped. Thus this option is also false
7184(C) Once the collision has occurred the data transmission is stopped as the jam signal is sent. Thus this option is also incorrect.
7185(D) To reduce the probability of collision on retransmissions an exponential back off mechanism is used. Thus, only this option is true

7279The size of the data count register of a DMA controller is 16 bits. The processor needs to transfer a file of 29,154 kilobytes from disk to main memory. The memory is byte addressable. The minimum number of times the DMA controller needs to get the control of the system bus from the processor to transfer the file from the disk to main memory is
7280Ans
7281Size of data count register of the DMA controller = 16 bits
7282Data that can be transferred in one go = 216 bytes = 64 kilobytes
7283File size to be transferred = 29154 kilobytes
