How to Compare Text in Python

Python like other programming languages supports comparison operators. These primarily use to test the condition in the program. Here's a list of operators that you can use in python programs. Comparison operators List of operators < <= > >= == != Is is not How to use comparison operators Here, I have assigned 23 to a and 11 to b. Then, I did apply all the comparison operators. The output is self-explanatory, and If you are in doubt while programming, remember to visit this page. Examples a = 23 b = 11 print("Is a greater than b?", a > b)           #greater than print("Is a less than b?", a < b)              #less than print("Is a greater or equal to b?", a >= b)   #greater or equal print("Is a less or equal to b?", a <= b)      #less or equal print("Is a equal to b (option 1)?", a == b)         #test for equality print("Is a equal to b (option 2)?", a is b)         #test for equality print("I

Limitations of Mobile Computing

What is Mobile Computing? Mobile computing ─ ability to use the technology to wirelessly connect to and use centrally located information and/or application software through the application of small, portable, and wireless computing and communication devices voice, data and multimedia communication standards Limitations Resource constraints: Battery Interference: the quality of service (QoS) Bandwidth: connection latency Dynamic changes in communication environment: variations in signal power within a region, thus link delays and connection losses Network Issues: discovery of the connection-service to destination and connection stability Interoperability issues: the varying protocol standards Security constraints: Protocols conserving privacy of communication
