Newbies seem to love posting glossaries, but they are typically full of errors and misunderstandings. I encourage newbies to avoid the practice.

The following terms have descriptions that are inaccurate or not applicable to Bitcoin:

13. Wallet Backup -- It says to update the backup every time a new address is generated. That is unnecessary and risky for a bitcoin wallet.
20. Wallet Address -- A Bitcoin wallets does not an address. It contains addresses.
23. Decentralization -- The description applies to business management. It does not apply to networks and protocols.
35. WIF -- OMFG The link you posted links to a description of WIFcoin. Clearly, you have no understanding of what WIF means.
37. Ransomware -- The term has no place in a glossary about Bitcoin.
