How to Work With Tuple in Python

Image
Tuple in python is one of the streaming datasets. The other streaming datasets are List and Dictionary. Operations that you can perform on it are shown here for your reference. Writing tuple is easy. It has values of comma separated, and enclosed with parenthesis '()'. The values in the tuple are immutable, which means you cannot replace with new values. #1. How to create a tuple Code: my_tuple=(1,2,3,4,5) print(my_tuple) Output: (1, 2, 3, 4, 5) ** Process exited - Return Code: 0 ** Press Enter to exit terminal #2. How to read tuple values Code: print(my_tuple[0]) Output: 1 ** Process exited - Return Code: 0 ** Press Enter to exit terminal #3. How to add two tuples Code: a=(1,6,7,8) c=(3,4,5,6,7,8) d=print(a+c) Output: (1, 6, 7, 8, 3, 4, 5, 6, 7, 8) ** Process exited - Return Code: 0 ** Press Enter to exit terminal #4.  How to count tuple values Here the count is not counting values; count the repetition of a given value. Code: sample=(1, 6, 7, 8, 3, 4, 5, 6, 7, 8) print(sample

Protocols: Top 6 Key Parts

In telecommunications, a protocol is a system of rules that allow two or more entities of a communications system to transmit information. The medium can be any kind of entity.

 What is PROTOCOL
  1. Important aspects of networks that are neither devices nor media are rules or protocols. These rules are the standards and protocols that specify how the messages are sent, how they are directed through the network, and how they are interpreted at the destination devices. 
  2. For example, in the case of Jabber instant messaging, the XMPP, TCP, and IP protocols are all important sets of rules that enable our communication to occur.
  3. These are the rules or standard that defines the syntax, semantics, and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both.

Communicating systems

They use well-defined formats (protocol) for exchanging messages. 
  • Each message has an exact meaning intended to elicit a response from a range of possible responses pre-determined for that particular situation. 
  • The specified behavior is typically independent of how it is to be implemented. Communications protocols have to be agreed upon by the parties involved. 
  • To reach an agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, so there is a close analogy between protocols and programming languages: protocols are to communications as programming languages are to computations.

Most commonly used devices in a networking

  1. Switch - the most common device for interconnecting local area networks 
  2. Firewall - provides security to networks 
  3. Router - helps direct messages as they travel across a network 
  4. Wireless Router - a specific type of router often found in home networks 
  5. Cloud - used to summarise a group of network devices, the details of which may be unimportant to the discussion at hand 
  6. Serial Link - one form of WAN interconnection, represented by the lightning bolt-shaped line
