Question

Assume we have a banking system that allows users to have joint accounts. On these joint accounts, two users may access the same account and perform withdraw and deposit concurrently. Describe how race condition can occur and in which areas of the system can it occur? Operating system course

Answer 1

Race Condition is a problem in a system that can occur when a system is access concurently by multiple users at the same time.
in the same way if one joint bank account is access by two users at the same time then race condition occur and it effect the account bank balance and the banking system.

for example:
if an account has a current bank balance is $1,000.
now one user can withdraw $500 and another deposit $5,000 to the account at the same time,

Withdraw Deposit
Read account balance Read account balance
Subtract $500 Add $5,000
write account balance    Write account balnace

Possible outcomes were: $5500, $500, $6000

so this s the result of race condition, that how it effects the bank balance of a joint account.
