Segregated Witness is an upgrade to the Bitcoin protocol in which technological innovation separated signature data from bitcoin transactions. Segregated Witness was implemented as a soft fork; a change that technically makes Bitcoin’s protocol rules more restrictive.
Segregated Witness is an upgrade to the Bitcoin protocol in which signature ("witness") data is separated from sender/receiver data to further optimize the structure of transactions.

SHA::
The Secure Hash Algorithm or SHA is a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST).
Simplified Payment Verification (SPV)::
SPV or simplified payment verification is a method for verifying that particular transactions were included in a block, without downloading the entire block. The method is used by some lightweight Bitcoin clients.

soft fork::
soft fork or Soft-Forking Change is a temporary fork in the blockchain which commonly occurs when miners using non-upgraded nodes don't follow a new consensus rule their nodes don’t know about.
