popularly known as Akbar the Great,[15] and also as Akbar I (Persian pronunciation: [akbar]),[16] was the third Mughal emperor, who reigned from 1556 to 1605. Akbar succeeded his father, Humayun, under a regent, Bairam Khan, who helped the young emperor expand and consolidate Mughal domains in the Indian subcontinent.
Akbar gradually enlarged the Mughal Empire to include much of the Indian subcontinent through Mughal military, political, cultural, and economic dominance. To unify the vast Mughal state, Akbar established a centralised system of administration and adopted a policy of conciliating conquered rulers through marriage and diplomacy. To preserve peace and order in a religiously and culturally diverse empire, he adopted policies that won him the support of his non-Muslim subjects, including abolishing the sectarian tax and appointing them to high civil and military posts.
Under Akbar, Mughal India developed a strong and stable economy, which tripled in size and wealth, leading to commercial expansion and greater patronage of an Indo-Persian culture. Akbar's courts at Delhi, Agra, and Fatehpur Sikri attracted holy men of many faiths, poets, architects, and artisans, and become known as centres of the arts, letters, and learning. Timurid and Perso-Islamic culture began to merge and blend with indigenous Indian elements into a distinct style of Mughal arts, including painting and architecture. Disillusioned with orthodox Islam and perhaps hoping to bring about religious unity within his empire, Akbar promulgated Din-i Ilahi, a syncretic creed derived mainly from Islam and Hinduism as well as elements of Zoroastrianism and Christianity.popularly known as Akbar the Great,[15] and also as Akbar I (Persian pronunciation: [akbar]),[16] was the third Mughal emperor, who reigned from 1556 to 1605.

A network switch (sometimes known as a switching hub) is a computer networking device that is used to connect devices together on a computer network by performing a form of packet switching. A switch is considered more advanced than a hub because a switch will only send a message to the device that needs or requests it, rather than broadcasting the same message out of each of its ports

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

4. 8-1 CIRCUIT-SWITCHED NETWORKS A circuit-switched network consists of a set of switches connected by physical links. A connection between two stations is a dedicated path made of one or more links. However, each connection uses only one dedicated channel on each link. Each link is normally divided into n channels by using FDM or TDM. Three Phases Efficiency Delay Circuit-Switched Technology in Telephone Networks Topics discussed in this section:
5. A circuit-switched network is made of a set of switches connected by physical links, in which each link is divided into n channels. Note
7. In circuit switching, the resources need to be reserved during the setup phase; the resources remain dedicated for the entire duration of data transfer until the teardown phase. Note
8. As a trivial example, let us use a circuit-switched network to connect eight telephones in a small area. Communication is through 4-kHz voice channels. We assume that each link uses FDM to connect a maximum of two voice channels. The bandwidth of each link is then 8 kHz. Figure 8.4 shows the situation. Telephone 1 is connected to telephone 7; 2 to 5; 3 to 8; and 4 to 6. Of course the situation may change when new connections are made. The switch controls the connections. Example 8.1
9. Figure 8.4 Circuit-switched network used in Example 8.1
10. As another example, consider a circuit-switched network that connects computers in two remote offices of a private company. The offices are connected using a T-1 line leased from a communication service provider. There are two 4 × 8 (4 inputs and 8 outputs) switches in this network. For each switch, four output ports are folded into the input ports to allow communication between computers in the same office. Four other output ports allow communication between the two offices. Figure 8.5 shows the situation. Example 8.2
11. Figure 8.5 Circuit-switched network used in Example 8.2
12. Figure 8.6 Delay in a circuit-switched network
13. Switching at the physical layer in the traditional telephone network uses the circuit-switching approach. Note
14. 8-2 DATAGRAM NETWORKS In data communications, we need to send messages from one end system to another. If the message is going to pass through a packet-switched network, it needs to be divided into packets of fixed or variable size. The size of the packet is determined by the network and the governing protocol. Routing Table Efficiency Delay Datagram Networks in the Internet Topics discussed in this section:
15. In a packet-switched network, there is no resource reservation; resources are allocated on demand. Note
16. Figure 8.7 A datagram network with four switches (routers)
17. Figure 8.8 Routing table in a datagram network
18. A switch in a datagram network uses a routing table that is based on the destination address. Note
19. The destination address in the header of a packet in a datagram network remains the same during the entire journey of the packet. Note
21. Switching in the Internet is done by using the datagram approach to packet switching at the network layer. Note
22. 8-3 VIRTUAL-CIRCUIT NETWORKS A virtual-circuit network is a cross between a circuit-switched network and a datagram network. It has some characteristics of both. Addressing Three Phases Efficiency Delay Circuit-Switched Technology in WANs Topics discussed in this section:
25. Figure 8.12 Switch and tables in a virtual-circuit network
26. Figure 8.13 Source-to-destination data transfer in a virtual-circuit network
27. Figure 8.14 Setup request in a virtual-circuit network
28. Figure 8.15 Setup acknowledgment in a virtual-circuit network
29. In virtual-circuit switching, all packets belonging to the same source and destination travel the same path; but the packets may arrive at the destination with different delays if resource allocation is on demand. Note
30. Figure 8.16 Delay in a virtual-circuit network
31. Switching at the data link layer in a switched WAN is normally implemented by using virtual-circuit techniques. Note
32. 8-4 STRUCTURE OF A SWITCH We use switches in circuit-switched and packet-switched networks. In this section, we discuss the structures of the switches used in each type of network. Structure of Circuit Switches Structure of Packet Switches Topics discussed in this section:
33. Figure 8.17 Crossbar switch with three inputs and four outputs
35. In a three-stage switch, the total number of crosspoints is 2kN + k(N/n) 2 which is much smaller than the number of crosspoints in a single-stage switch (N 2 ). Note
36. Design a three-stage, 200 × 200 switch (N = 200) with k = 4 and n = 20. Solution In the first stage we have N/n or 10 crossbars, each of size 20 × 4. In the second stage, we have 4 crossbars, each of size 10 × 10. In the third stage, we have 10 crossbars, each of size 4 × 20. The total number of crosspoints is 2kN + k(N/n) 2 , or 2000 crosspoints. This is 5 percent of the number of crosspoints in a single-stage switch (200 × 200 = 40,000). Example 8.3
37. According to the Clos criterion: n = (N/2) 1/2 k > 2 n – 1 Crosspoints ≥ 4N [(2N) 1/2 – 1] Note
38. Redesign the previous three-stage, 200 × 200 switch, using the Clos criteria with a minimum number of crosspoints. Solution We let n = (200/2) 1/2 , or n = 10. We calculate k = 2n − 1 = 19. In the first stage, we have 200/10, or 20, crossbars, each with 10 × 19 crosspoints. In the second stage, we have 19 crossbars, each with 10 × 10 crosspoints. In the third stage, we have 20 crossbars each with 19 × 10 crosspoints. The total number of crosspoints is 20(10 × 19) + 19(10 × 10) + 20(19 ×10) = 9500 . Example 8.4
