Different types of connections are..

-A network is two or more devices connected through links.

-There are two possible types of connections: point-to-point and multipoint.

-A point-to-point connection provides a dedicated link between two devices.

Explain the different types of topologies

-Star network…
In star topology each device in the network is connected to a central device called hub. Unlike Mesh topology, star topology doesn't allow direct communication.

-Ring network…
A number of repeaters are used for Ring topology with large number of nodes, because if someone wants to send some data to the last node in the ring topology

-Bus network…
In bus topology there is a main cable and all the devices are connected to this main cable through drop lines. There is a device called tap that connects the drop 

-tree topology…
Tree topologies have a root node, and all other nodes are connected which form a hierarchy. So it is also known as hierarchical topology. This topology integrates

Different type of networks

-Computer network…
Virtual Private Network (VPN). By extending a private network across the Internet, a VPN lets its users send and receive data.

-LAN…
Using routers, LANs can connect to wide area networks (WANs, explained below) to rapidly and safely transfer data. 3. Wireless Local Area Network (WLAN).

-Wide area network…
Wide area network, or WAN. In terms of purpose, many networks can be considered general purpose, which means they are used for everything from sending files etc.

-Metropolitan area network…
MAN or Metropolitan area Network covers a larger area than that of a LAN and smaller area as compared to WAN. It connects two or more computers that are apart.

-Wireless LAN…
WLAN (Wireless Local Area Network) helps you to link single or multiple devices using wireless communication within a limited area like home, school, or office 

-Wireless network…
A Wireless Local Area Network or WLAN is a network that is used to connect different devices without using wires etc.

-Storage area network…
Storage Area Network is a type of network which allows consolidated, block-level data storage. It is mainly used to make storage last longer etc.

-Personal area network…
PAN can be used for establishing communication among these personal devices for connecting to a digital network and the internet.

-Campus area network…
A Metropolitan Area Network or MAN is consisting of a computer network across an entire city, college campus, or a small region. This type of network is large.

Explain your own understand about protocol and standards

A protocol defines a set of rules used by two or more parties to interact between themselves. A standard is a formalized protocol accepted by most of the parties that implement it.

explain layers in OSI model

Physical, Data Link, Network, Transport, Session, Presentation, and Application.

Explain layers in tcp/ip model

Four layers of TCP/IP model are 1) Application Layer 2) Transport Layer 3) Internet Layer 4) Network Interface. ... It is also known as a network layer. Transport layer builds on the network layer in order to provide data transport from a process on a source system machine to a process on a destination system.

what are the peer to peer processing

In peer-to-peer (P2P) networking, a group of computers are linked together with equal permissions and responsibilities for processing data. Unlike traditional client-server networking, no devices in a P2P network are designated solely to serve or to receive data

Everybody at a company is assigned a unique 9 digit ID. How many unique IDs exist?
timama [110]

Answer:

3,265,920 unique ID exist.

Explanation:

The nine digits are from 0 to 9, there are ten bits from 0 -9,

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

The first is select from the highest bit (9), and the second is selected at random from 0 - 9, the third bit to the last must be unique and different from each other;

number of unique IDs = 9 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2

Multiplying the nine bits of unique IDs = 3,265,920.

What general strategies can the network managers use to reduce congestions?
Harrizon [31]

Answer:

 There are different types of strategies that can be used by the network manager for reducing the congestion are as follows:

  • By monitoring the traffic of the network properly we can easily reduce the congestion in the network.
  • By segmenting the network properly, it helps to reduce the network congestion.
  • We can also reconfiguring the TCP/IP (Transmission control protocol) setting on the network.
  • We can also use the backpressure routing technique.

5. Write few lines of code that creates two arrays with malloc. Then write a statement that can create a memory leak. Discuss wh
Darina [25.2K]

Answer:

 // function with memory leak  

void func_to_show_mem_leak()  {  

int *pointer;

pointer = malloc(10 * sizeof(int));

*(pointer+3) = 99;}  

 

// driver code  

int main()  

{  

    // Call the function  

   // to get the memory leak  

   func_to_show_mem_leak();  

     return 0;  }

Explanation:

Memory leakage occurs when programmers allocates memory by using new keyword and forgets to deallocate the memory by using delete() function or delete[] operator. One of the most memory leakage occurs by using wrong delete operator. The delete operator should be used to free a single allocated memory space, whereas the delete [] operator should be used to free an array of data values.
