(i) Protein Databases: The protein database is a collection of sequences from several sources, including translations from annotated coding regions in GenBank, RefSeq and TPA, as well as records from SwissProt, PIR, PRF, and PDB. Protein sequences are the fundamental determinants of biological structure and function. Protein databases are more specialized than primary sequence databases. They contain information derived from the primary sequence databases. 

Example : PIR, TIGR, PFam, PRINTS, ProDom, ProSite, ALIGN, SWISS-PROT & TREMBL, etc. 

(ii) Hardware and Software of computers 

Hardware: Hardware is the collection of physical components that constitutes a computer system including peripherals such as the monitor, mouse, keyboard, computer data storage, hard drive disk (HDD), system unit (graphic cards, sound cards, memory motherboard and chips), etc., all of which are physical objects that can be touched. In contrast, software is instructions that can be stored and ran by hardware.
Software: Written programs or procedures or rules and associated documentation pertaining to the operation of a computer system and that are stored in read/write memory. Bases on their goals, they could be Application software, System software, Malicious software or malware, etc.
