How does blockchain technology ensure data integrity and security in decentralized systems?
Blockchain technology uses cryptographic techniques and distributed consensus mechanisms to create a tamper-proof ledger of transactions across a network of nodes. Each block in the chain contains a cryptographic hash of the previous block, making it resistant to unauthorized changes.

The key differences between a traditional savings account and a certificate of deposit (CD) are:
Liquidity: A traditional savings account allows for easy access to funds, typically offering unlimited withdrawals and deposits. In contrast, a CD requires you to deposit a sum of money for a fixed period, during which you cannot withdraw funds without incurring penalties.
Interest Rates: Savings accounts generally offer lower interest rates compared to CDs. However, savings account interest rates may fluctuate over time, while CD rates are fixed for the duration of the term.
Term Length: Savings accounts have no fixed term and can be used indefinitely. CDs, on the other hand, have fixed terms ranging from a few months to several years, during which the funds are locked in.
FDIC Insurance: Both savings accounts and CDs held at FDIC-insured banks are protected by the Federal Deposit Insurance Corporation (FDIC) up to the maximum allowed limit per depositor, per bank.

TCP is a connection-oriented protocol that provides reliable and ordered delivery of data packets over a network. It ensures that data is transmitted without errors and in the correct sequence by establishing a connection, acknowledging received packets, and retransmitting lost packets. UDP, on the other hand, is a connectionless protocol that prioritizes speed and efficiency over reliability. It sends data packets without establishing a connection or guaranteeing delivery, making it suitable for applications such as real-time communication and multimedia streaming where occasional packet loss is acceptable.
