Wireless network:
- In
computer network , the wireless network uses wireless data connections for connecting network nodes. - It is a process by which telecommunications network, business installations and homes avoid the costly process of introducing cables to provide connection between many equipment locations.
- Example of wireless network include Wireless Local Area Networks (WLANs), cell phone networks, satellite communication networks and wireless sensor network.
Explanation of Solution
Operation of wireless network in infrastructure mode:
- Infrastructure mode is a networking framework of 802.11 that uses access point to communicate with each other.
- With the use of infrastructure mode the wireless devices can communicate with each other.
- The operation of infrastructure mode where each wireless hosts are connected to the large network through base network which is termed as access point.
Mode of operation:
- If the network is not in the infrastructure mode, it is consider as an ad-hoc mode of operation.
- The ad-hoc mode communicates each other without the help of access point.
Difference between mode of operation and infrastructure mode:
Mode of operation | Infrastructure mode |
This device is used to communicate each other directly. |
The wireless devices can communicate with each other in the infrastructure mode. |
The access point is not used here to communicate with each other. |
Infrastructure mode need access point to communicate with each other. |
Ad-hoc mode communicate only with other ad-hoc devices. |
The access point controls wireless communication and offer many important benefits over an ad-hoc network. |
Security is less in ad-hoc mode when compare with infrastructure mode. |
It support high level security, possibly faster data transmission speeds. |

- 2. Jane, Jill, and Jenny have formed a band consisting of 3 instruments. (a) If each of them can play all 3 instruments, how many different arrangements are possible? (b) What if Jane can play all 3 instruments, but Jill and Jenny can each play only piano and drums?arrow_forward4. A person has 9 friends, of whom 5 will be invited to a party. (a) How many choices are there if 2 of the friends are feuding and will not attend together? (b) How many choices if 2 of the friends will only attend together?arrow_forward5. There are 3 people in a room, and we are curious whether two of them have their birthday in the same month. We record the triplet that describes the month of birthday for each person. E.g., (Oct, Jan, Jul) is one possible triplet/outcome. (Since each month applies to a specific person, (Oct, Jan, Jul) is not the same as (Jan, Jul, Oct), so order is important.) (a) How many possible outcomes are there? (b) In how many of these outcomes do all three people have their birthday in different months? (c) In how many of these outcomes do at least two people have their birthday in the same month?arrow_forward
- 1. We have 8 blocks, of which 4 are green, 2 are red, 1 is white, and 1 is black. If we put the blocks in a line, how many arrangements are possible?arrow_forward3. (a) In how many ways can 3 cats and 3 dogs sit in a row? (b) In how many ways can 3 cats and 3 dogs sit in a row if the cats and the dogs are each to sit together? (c) In how many ways if only the cats must sit together? (d) In how many ways if no two animals of the same type are allowed to sit together?arrow_forwardthe gate level and the transistor level for a certain circuit are given below.

Write a method to display the moon's details along with its parent planet. • Task 2: Modify the 'Galaxy' class to calculate the total mass of all celestial bodies it contains. Implement a method `total_mass() for this purpose. • Task 3: Create a class 'BlackHole` that inherits from `Celestial Body` and adds properties like event_horizon_radius' and 'spins. Implement a method to display black hole details. • Task 4: Develop a simulation where a user can create multiple galaxies and display their celestial bodies in a hierarchical format using inheritance. 10/06/1446arrow_forwardPlease solve q2arrow_forward
- self.sAge = age super().__init_("Rahul", age) # inheriting the properties of def displayInfo(self): print(self.sName, self.sAge) obj = Student("Mayank", 23) obj.display() obj.displayInfo() parent class we created the object 'obj' of the child class. When we called the constructor of the child class 'Student', it initialized the data members to the values passed during the object creation. Then using the super() function, we invoked the constructor of the parent class. Asst.L. Manar Hamza Bashaa 2024-2arrow_forwardObject-oriented programming tion defines a new type of that class. Lec 7: Static Members Object-Oriented Programming Assignment: Create a class named StudentRecords and add a static variable named records, which is a list shared among all objects of the class. Then add a method named add_record that takes a student's name as input and appends it to the shared records list.arrow_forwardpython Tasks 6 • Task 1: Develop a Student Profile class with private attributes for `name` and __ grades` (a list of grades), and methods to add a grade and calculate the average. • Task 2: Create a `Playlist class that stores song titles in a private list, with methods to add a song, remove a song, and display the current playlist. • Task 3: Implement a `Temperature Sensor class with a private `_temperature attribute, and methods to set and get the temperature in both Celsius and Fahrenheit. • Task 4: Build a Library Book class with private attributes for the title and availability status; include methods to check out, return, and display the book's availability ⚫Task 5(homework): Create a 'Counter` class with a private _ count attribute, and include get_count()` and `set_count(value)` methods to access and modify it.
