What Does the Term "Channel Capacity" Imply?The maximum quantity of traffic or signal that may pass over a particular infrastructure channel is channel capacity. It can be used to assess the capacity of a channel or conduit in computer science, electrical engineering, and other areas.The apparent advantages of analyzing channel analysis have made this word a household term in the IT world. Engineers might be tasked with determining how much data can flow through a particular fiber-optic network or how much data can pass via a WAN with wired and wireless components. The difficulty of deciding channel capacity and the ... Read More

Since it follows a simple ... Read More
What is Alias/Secondary IP Address?IP aliasing is the process of assigning several IP addresses to a network interface. It allows a single node on a network to have many network connections, each having a different purpose.Multiple network addresses can be provided on a single physical interface using IP aliasing. One rationale for doing so could be to make a single computer appear to be several computers.How to configure?In Linux, to use IP aliasing, the Kernel must be compiled with network aliasing and IP options. Then the aliases would attach to the virtual network device or interface with a specific virtual ... Read More
What is RDMA?The access of one computer's memory by another in a network without the involvement of any computer's operating system, processor, or cache is referred to as RDMA. Because many resources are freed up, it aids in improving system throughput and performance.On a remote machine, read and write operations can be performed without being interrupted by the CPU of that machine. The data transfer rate is increased, and networking latency is reduced, thanks to this technology. It uses zero-copy networking for transferring data directly into system buffers by enabling network adapters.RDMA was earlier used only in high-performance computing (HPC) ... Read More
Inter-Switch LinkISL is a VLAN protocol that stands for Inter-Switch Link. Cisco's ISL is a proprietary protocol that is only utilized between Cisco switches.A point-to-point VLAN context can support up to 1000 VLANs and is only compatible with Fast Ethernet and Gigabit Ethernet networks.ISL encapsulates an Ethernet frame with a header that sends VLAN IDs between switches and routers. The tag in IEEE 802.1Q is internal.An Ethernet encapsulated ISL frame will typically start at 94 bytes and grow to 1548 bytes in size. Encapsulation is used to develop the protocol.The frame is given a 26-byte header and a 4-byte CRC ... Read More
When it is required to find the Fibonacci sequence using the method of recursion, a method named ‘fibonacci_recursion’ is defined, that takes a value as parameter. It is called again and again by reducing the size of the input.Below is a demonstration of the same:Exampledef fibonacci_recursion(my_val): if my_val
When it is required to inverse the dictionary values to a list, a simple iteration and ‘append’ method is used.Below is a demonstration of the same −from collections import defaultdict my_dict = {13: [12, 23], 22: [31], 34: [21], 44: [52, 31]} print("The dictionary is :") print(my_dict) my_result = defaultdict(list) for keys, values in my_dict.items(): for val in values: my_result[val].append(keys) print("The result is :") print(dict(my_result))OutputThe dictionary is : {34: [21], 44: [52, 31], 13: [12, 23], 22: [31]} The result is : {52: [44], 31: [44, 22], 12: [13], 21: [34], ...

When it is required to sort a list of strings based on the ‘K’ number of character frequency, the ‘sorted’ method, and the lambda function is used.ExampleBelow is a demonstration of the same −my_list = ['Hi', 'Will', 'Jack', 'Python', 'Bill', 'Mills', 'goodwill'] print("The list is : " ) print(my_list) my_list.sort() print("The list after sorting is ") print(my_list) K = 'l' print("The value of K is ") print(K) my_result = sorted(my_list, key = lambda ele: -ele.count(K)) print("The resultant list is : ") print(my_result)OutputThe list is : ['Hi', 'Will', 'Jack', 'Python', 'Bill', 'Mills', 'goodwill'] The list after sorting is ...
