Question 46
Comprehension:
Read the passage carefully and answer questions that follow:
There is no doubt that the market a reality and political economy as a theory played an important role in the liberal critique. But liberalism is neither the consequence nor the development of these; rather, the market played, in the liberal critique, the role of a “test”, a locus of privileged experience where one can identify the effects of excessive govern-mentality and even weight their significance; the analysis of the analysis of the mechanisms of “dearth” or more generally, of the grain trade in the middle of the eighteenth century, was meant to show the point at which governing was always governing too much. Therefore, an analysis to make visible, in the form of evidence, the formation of the value and circulation of wealth-or, on the contrary, and analysis pre-supposing the intrinsic invisibility of the connection between individual profit-seeking and the growth of collective wealth-economics, in any case, shows a basic incompatibility between the optimal development of the economic process and maximization of government procedures. It is by this, more than the play of ideas, the French or English economists broke away from mercantilism and commercialism; they freed reflection on economic practice from the hegemony of the “reason of state” and from the saturation of governmental intervention. By using it as a measure of “governing too much”, they placed it at the limit of governmental action action. Liberalism does not derive from juridical thought any more than it does from an economic analysis. It is not the idea of a political society, but the result of search for a liberal technology of government.

UGC NET Computer Science June 2019 -II | Question 1 (Shift-I)

Question 1
1. Consider the poset ({3,5,9,15,24,45},|).
Which of the following is correct for the given poset?
  1. (1) There exists a greatest element and a least element
  2. (2) There exists a greatest element but not a least element
  3. (3) There exists a least element but not a greatest element
  4. (4) There does not exist a greatest element and a least element
Answer : (4) There does not exist a greatest element and a least element

Explanation Question 1

The division symbol ‘|’ is a partial ordering on the set {3,5,9,15,24,45}.
Lets draw Hasse Diagram for the given partially ordered set, or poset.

Hasse Diagram for given poset ({3,5,9,15,24,45},|)

For given poset, We can not choose greatest element because there are two maximal elements 24 and 45.

Similarly, We can not choose here least element because there are two minimal elements 5 and 3 at same level in Hasse diagram.

So, there is no possibility of greatest and least element.

So, option (4) is correct answer

Reference : Partial Orderings - partially ordered set / poset

Reference : Greatest element of a subset S of a partially ordered set (poset)

UGC NET PAPER 2 June 2019 Question 83 (Shift-I)

Question 83
83. You are designed a link layer protocol for a link with bandwidth of 1 Gbps (109 bits/second) over a fiber link with length of 800 km. Assume the speed of light in this medium is 200000 km/second. What is the propagation delay in this link?
  1. 1. 1 millisecond
  2. 2. 2 millisecond
  3. 3. 3 millisecond
  4. 4. 4 millisecond
Answer : 4. 4 millisecond

Explanation Question 83

Given data:
Fiber link length = distance = 800 km.
Speed of light in this medium = velocity = 200000 km/second
and we know that 1 sec is equel to 1000 milliseconds

Solution:
Propagation delay : Time taken by the first bit to travel from sender to receiver end of the link.

Propagation delay = distance/transmission speed
Propagation delay
= 800km / ( 200000km /sec)
= ( 800 / 200000) sec
= ( 800 / 200 ) milliseconds
= 4 ms

So, option 4 is correct answer

Question 85
85. Consider the following two statements with respect to IPv4 in computer networking:
P: The loopback(IP) address is a member of class B network
Q: The loopback(IP) address is used to send a packet from host to itself
What can you say about the statements P and Q?
  1. 1. P-True: Q-False
  2. 2. P-False; Q-True
  3. 3. P-True; Q-True
  4. 4. P-False; Q-false
Answer : 2. P-False; Q-True

Explanation Question 85

  • P: The loopback(IP) address is a member of class B network. Statement P is Flase.
    Explanation: The loopback(IP) address is a member of class A network. Any address between the range 127 . 0. 0. 0 to 127.255.255.255 can be used a loopback address but we can’t use 127 . 0. 0. 0 and 127.255.255.255 as loopback addresses.
  • Q: The loopback(IP) address is used to send a packet from host to itself. Statement Q is True.
    Explanation: IPv4 network standards reserve the entire address block 127.0.0.0/8 (more than 16 million addresses) for loopback purposes. That means any packet sent to any of those addresses is looped back. A loopback address is a special IP address, 127.0.0.1, reserved by InterNIC for use in testing network cards.It also allows information technology professionals to test IP software without worrying about broken or corrupted drivers or hardware.
So, option 2 is correct answer

Reference : localhost - loopback(IP) address

Reference 2 : What is a loopback address?

UGC NET PAPER 2 June 2019 Question 78 (Shift-I)

Question 78
78. Consider the following grammar:
S→ XY
X→ YaY | a and Y → bbX
Which of the following statements is/are true about the above grammar?
(a) Strings produced by the grammar can have consecutive three a's
(b) Every string produced by the grammar have alternate a and b
(c) Every string produced by the grammar have at least two a's
(d) Every string produced by the grammar have b's in multiple of 2.
  1. 1. (a) only
  2. 2. (b) and (c) only
  3. 3. (d) only
  4. 4. (c) and (d) only
Answer : 4. (c) and (d) only

Explanation Question 78

Given grammar generates strings which contains "b" in multiple of 2 and number of "a" at least 2.

This grammar generate a string set of this form, L = { abba, bbaabbabba, abbbbaabba, . . . . . . . . . . . . . }

  • Statement (a) is not true because the grammar can generate two consecutive a’s but not three consecutive a’s.
  • Statement (b) is not true because every string produced by the grammar do not have alternate a and b. The grammar can generate two b’s together it means that every string do not have alternate "a" and "b".
  • Statement (c) is true because every string produced by the grammar have at least two a's.
  • Statement (d) is true because every string produced by the grammar have b's in multiple of 2.

This is satisfied by statements c and d. But statements a and b are not satisfied.
Hence statements c and d is right.

So, option 4 is correct answer

Options:
  1. 1. ARP
  2. 2. DNS
  3. 3. RARP
  4. 4. ICMP
Answer : 3 RARP

Explanation Question 82

Reverse Address Resolution Protocol

It is used to get IP address with the help of Physical address(MAC Address).

RARP was used by old diskless workstations. These old hosts don’t have a disk so there is nothing to store an IP address on. They do have a hardcoded MAC address though. When the workstation starts, it broadcasts a RARP request with its own MAC address.

On the same network as the hosts, we have a RARP server listening to the RARP requests. This server has a table that contains a combination of MAC and IP addresses. When it receives a RARP request, it checks its table to find the matching IP address for the MAC address in the RARP request packet. The RARP server then replies with a RARP reply to the host. When the host receives the RARP reply, it knows its IP address.
