Technical Terms - Hardware (A-Z) - Error Correction Code (ERR)

What does ECC stand for in the context of computer memory?

• Enhanced Computer Chip

• External Cache Controller

• Electronic Control Circuit

• Error Correction Code

Which type of RAM modules use ECC to protect data from corruption?

• DDR3 RAM

• ECC RAM

• SODIMM RAM

• RDRAM

What is the main cause of most computer memory errors?

• Power surges

• Software bugs

• Overheating

• Single-bit errors

What is the purpose of a parity bit in ECC memory?

• Generate error correction codes

• Track how many bits have a value of 1

• Increase memory speed

• Store additional data

Why do ECC memory modules include more chips than non-ECC RAM?

• To store parity bits

• To save power

• To increase memory speed

• To reduce cost

Which type of systems typically use ECC RAM?

• Gaming consoles

• Smartphones

• Workstations and servers

• Digital cameras

What happens if a single-bit error occurs in ECC memory?

• The memory module shuts down

• The affected bit is flipped back to its original state

• The data is permanently lost

• The system crashes

Why is ECC memory more expensive than non-ECC memory?

• Due to faster performance

• Due to lower demand

• Due to higher manufacturing costs

• Due to extra circuitry and chips

Which type of computer systems typically use non-ECC RAM?

• High-uptime servers

• Medical equipment

• Desktop and laptop computers

• Aircraft control computers

How does ECC memory affect system performance compared to non-ECC memory?

• ECC memory is slower

• ECC memory is faster

• ECC memory consumes less power

• ECC memory has no impact on performance
