The runtime struct passed to programs for each account in an instruction: `AccountInfo { key, is_signer, is_writable, lamports, data, owner, executable, rent_epoch }`. In native programs, the entrypoint receives a slice of AccountInfos. Anchor abstracts this with typed account structs but AccountInfo is available via `to_account_info()`.

The fundamental data storage unit on Solana. Every piece of state is stored in an account identified by a 32-byte public key. Accounts hold a lamport balance, an owner program, a data byte array (up to 10MB), and an executable flag. Only the owning program can modify an account's data, but anyone can credit lamports to it.
Executable code deployed on-chain, equivalent to a smart contract on other blockchains. Programs are stateless—they store no data themselves but read/write data in separate accounts they own. Programs are compiled to SBF bytecode and loaded via the BPF Loader. Every program has a unique Program ID (its account's public key).

A pubkey with administrative privileges over a resource—such as the mint authority (can mint tokens), freeze authority (can freeze accounts), upgrade authority (can upgrade a program), or the signer authorized to perform operations on a PDA-controlled account. Authority is a convention, not a runtime concept.
The byte array stored in an account that holds program-specific state. Data is typically serialized using Borsh and must be explicitly allocated at account creation. The maximum data size is 10MB. Programs are responsible for defining and managing their own data layout, including discriminators for type identification.
A temporary account used during Solana program deployment to hold the program's ELF binary before it is written to the program data account. The deployer creates a buffer account, uploads the compiled SBF binary in chunks via the Upgradeable BPF Loader's Write instruction, and then issues a Deploy or Upgrade instruction that copies the buffer contents to the final program data account. Buffer accounts can be closed after deployment to reclaim rent.

A single operation within a transaction that invokes a program. An instruction specifies: (1) the program ID to call, (2) an array of account metas (pubkey, is_signer, is_writable), and (3) an opaque data byte array. Programs decode the instruction data to determine which operation to perform.
An atomic unit of execution containing one or more instructions, a recent blockhash, and one or more signatures. All instructions in a transaction execute sequentially and atomically—if any instruction fails, the entire transaction reverts. Transactions have a 1,232-byte size limit (matching IPv6 MTU) and a default 200,000 CU budget.
