IGCSE Computer Science Quiz (Tr.WaiLinHtet)

What is the main characteristic of symmetric encryption?

• Uses two keys for encryption and decryption

• Uses one key for both encryption and decryption

• Does not require any keys

• Uses a public key for decryption only

Which encryption method is faster for large volumes of data?

• Asymmetric encryption

• Symmetric encryption

• No encryption

• Both are equally fast

What is a key advantage of asymmetric encryption?

• It is faster than symmetric encryption

• It does not require a private key

• The private key is never shared

• It uses a single key for encryption and decryption

Which encryption method uses a public key to encrypt data?

• Symmetric encryption

• Asymmetric encryption

• Both symmetric and asymmetric

• Neither symmetric nor asymmetric

Why is symmetric encryption preferred for encrypting large files?

• It is more secure than asymmetric encryption

• It is faster and more efficient

• It uses two keys, making it more reliable

• It does not require a key

In asymmetric encryption, who can access the private key?

• Anyone with the public key

• Only the intended recipient

• The network administrator

• Both sender and receiver

Which of the following is an example of symmetric encryption?

• RSA

• AES

• SSL

• TLS

Who assigns an IP address to a device?

• The device manufacturer

• The network, router, or ISP

• The user manually

• The operating system

What is a key difference between a MAC address and an IP address?

• A MAC address can be changed, but an IP address cannot

• A MAC address is assigned by the manufacturer, while an IP address is assigned by the network

• A MAC address is denary, while an IP address is hexadecimal

• A MAC address is 32-bit, while an IP address is 48-bit

How many groups of values does an IPv4 address have?

• 6

• 8

• 4

• 12
