Nowadays people need to transfer their information via messages or the internet. They send and receive so much valuable data throughout the entire day. But transferring information can be so much risky. Sometimes during transferring data, some data can be hacked or manipulated through various sources. These types of cybercrime such as DDoS attacks, Phishing attacks, Ransomware attacks are happening every day. So transferring data safely is one of our main concerns. For this, encoding and decoding are very helpful in this aspect. They play a very essential role in communication to prevent different types of cyber-attacks. So, to know about Encoding VS Decoding, this is the right place for you.
What is Encoding?
Encoding is a way of sending data in the communication process. It is a kind of turning messages into some other messages while sending them. The messages can be manipulated or locked which cannot be viewed by people other than the specific server or receiver. It is generally done by the encoder. It is a device that converts real messages into coded messages. It has a combined circuit that can convert binary data with 2N lines into N lines in the output. It is one of the best ways to achieve security in information sharing. To let you clear, you may confuse encoding with encryption. But they are two different things.

What is Decoding?
Decoding is the opposite the encoding. Encoding is the process of turning the coded messages into real messages. The sender sends messages by encoding them to the receiver. The receiver decodes the messages to get the information. They use some decoder to decode the messages. It is generally a combined circuit that converts n lines of input into 2n lines of output data. It is one of the secured ways of receiving messages without leaking any information and prevents the injection of malware, or viruses.
Similarities between Encoding and Decoding
There are some similarities between encoding and decoding as they related to each other.. These are
- Both are the way of communication.
- Both encoding and decoding are dependent on each other.
- Without decoding, the encoded message is useless.
- Both worked through the combined circuit.
Differences between Encoding and Decoding
The differences between encoding and decoding are given below.
- Device: Encoder is used in encoding messages and decoder is used in decoding messages.
- Covert data: The circuit used in the encoder mainly converts the message or data signal into a coded digit or message that one cannot understand. On the other hand, Decoder does the opposite task. It converts the coded digits or bits that means binary data into real information or message.
- Type of input: The encoder accepts the data input as the active data signal input. But decoder accepts input as binary data which is coded.
- The number of inputs: The encoder can accept 2n number of digits as input. Whereas, decoder accepts n number of digits as input.
- The number of output: In the encoder, the line number of output is n. And in the decoder, the line number of output is 2n.
- Gate: In the encoder, generally OR gate is used. On the other hand, the basic gates of the decoder are AND, NOT.
- Operation Type: The operation of the encoder is simpler than the operation of the decoder.
- Installation side: The circuit of an encoder is installed at the end of the transmitter. But the circuit of a decoder is installed at the side of receiving.
People nowadays say that ‘Data is the new currency. So data security is a must in communication. Encoding vs decoding both are important things in communication. They are very useful for securing information. When cybercrime is increasing, we all should know about encoding and decoding. Also, you can prevent cyber-attacks like ransomware attacks, phishing techniques, DDos attacks if you remain concerns about these cyber attacks that can do so harm to you as well as your organization. Though they have the difference, both encoding and decoding are related to each other. Without decoding, you cannot get the actual information. After reading the article, now we hope you know all about Encoding VS Decoding and their influences on communication technology.
