703(B) 800 to 1000
704(C) 1400 to 1600
705(D) 1500 to 1700
706Explanation:  Given that at the time of Time Out, Congestion Window Size is 32KB32KB and RTT = 100ms100ms,
707          When Time Out occurs, for the next round of Slow Start, 
708          Threshold = size of congestion window2size of congestion window2 ,
709          Threshold = 16KB

864A 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.
865(A) 36
866(B) 32
867(C) 28
868(D) 40
869Explanation: A page table entry has following number of bits.
8701 (valid bit) + 
8711 (dirty bit) + 
8723 (permission bits) + 
873x bits to store physical address space of a page.
874
875Value of x = (Total bits in physical address) - 
876             (Total bits for addressing within a page)
877Since size of a page is 8 kilobytes, total bits needed within
878a page is 13.
879So value of x = 32 - 13 = 19
880
881Putting value of x, we get size of a page table entry =
882                                   1 + 1 + 3  + 19 = 24bits.
883
884Number of page table entries 
885           = (Page Table Size) / (An entry size)
886           =  (24 megabytes / 24 bits)                             
887           =  223
888
889Vrtual address Size 
890             = (Number of page table entries) * (Page Size)
891             =  223 * 8 kilobits
892             = 236  
893Therefore, length of virtual address space = 36

1355The resources involved must be unshareable; otherwise, the processes would not be prevented from using the resource when necessary.
13562.	hold and wait or partial allocation
1357The 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.
13583.	no pre-emption
1359The 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.
13604.	resource waiting or circular wait

2359A half adder is implemented with XOR and AND gates. A full adder is implemented with two half adders and one OR gate. The propagation delay of an XOR gate is twice that of an AND/OR gate. The propagation delay of an AND/OR gate is 1.2 microseconds. A 4-bit ripple-carry binary adder is implemented by using four full adders. The total propagation time 
2360of this 4-bit binary adder in microseconds is ____________.
2361A Ripple Carry Adder allows to add two n-bit numbers. It uses half and full adders. Following diagram shows a ripple adder using full adders.
2362 
2363Let us first calculate propagation delay of a single
23641 bit full adder.
2365
2366Propagation Delay by n bit full adder is (2n + 2) 
2367gate delays.
2368[See this for formula].
2369
2370Here n = 1, so total delay of a 1 bit full adder 
2371is (2 + 2)*1.2 = 4.8 ms
2372
2373Delay of 4 full adders is = 4 * 4.8 = 19.2 ms

2512Maximum sequence number in GBN is same as window size.
2513For sequence bits = n, number of sequence numbers = 2n and window size = 2n - 1
2514Consider n = 3, sequence numbers will be 23 = 8 ( i.e. from 0 - 7 )
2515and maximum window size = 23 - 1 = 7 i.e  window will carry frames  from 0 to 6 which are 7 in number.

3250A 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
3251Number of sets = cache size / sizeof a set 
3252
3253Size of a set = blocksize * no. of blocks in a set  
3254= 8 words * 4 (4-way set-associative) 
3255= 8*4*4 (since a word is 32 bits = 4 bytes) 
3256= 128 bytes. 
3257
3258So, number of sets = 16 KB / (128 B) = 128
3259Now, we can divide the physical address space equally between these 128 sets. So, the number of bytes each set can access 
3260= 4 GB / 128 
3261= 32 MB 
3262= 32/4 = 8 M words = 1 M blocks. (220 blocks) 
3263
3264So, we need 20 tag bits to identify these 220 blocks.

3354DMA is useful for the operations
3355DMA is useful for transferring data between memory and devices if large volume of data is to be transferred, or the devices have small response times. Because after setting up buffers, pointers, and counters for the I/O device, the device controller transfers an entire block of data directly to or from its own buffer storage to memory, with no intervention by the CPU. Only one interrupt is generated per block, rather than the one interrupt per byte (or word) generated for low-speed devices.
3356Alternatively, you may simply say:
3357DMA is useful for transferring large quantities of data between memory and devices. It eliminates the need for the CPU to be involved in the transfer, allowing the transfer to complete more quickly and the CPU to perform other tasks concurrently.
