Understanding Digital Certificates and RISC Architecture

What is a digital certificate primarily used for in digital communications?

• Encrypting data

• Authenticating the identity of a user or device

• Storing passwords

• Compressing files

Which of the following is NOT a type of digital certificate?

• SSL/TLS Certificate

• Code Signing Certificate

• Domain Name Certificate

• Email Certificate

What role does a Certificate Authority (CA) play in the issuance of digital certificates?

• It encrypts the data being transmitted

• It verifies the identity of the certificate requester

• It stores the digital certificates

• It generates public and private keys

Which of the following best describes the process of creating a digital signature?

• Encrypting the entire document with a public key

• Hashing the document and encrypting the hash with a private key

• Encrypting the document with a private key

• Hashing the document and encrypting the hash with a public key

In RISC architecture, what is the primary function of registers?

• To store data temporarily for quick access

• To permanently store data

• To manage network connections

• To execute complex instructions

What is the main advantage of pipelining in RISC processors?

• It increases the clock speed of the processor

• It allows multiple instructions to be processed simultaneously

• It reduces the power consumption of the processor

• It simplifies the instruction set

Which of the following architectures is characterized by a single instruction stream and multiple data streams?

• SISD

• SIMD

• MISD

• MIMD

In the context of digital certificates, what does SSL stand for?

• Secure Socket Layer

• Secure System Link

• Secure Software License

• Secure Signal Layer

What is the primary purpose of a digital signature?

• To encrypt the message content

• To verify the authenticity and integrity of a message

• To compress the message for faster transmission

• To convert the message into a different format

Which of the following is a characteristic of MIMD architecture?

• It uses a single instruction stream

• It processes multiple instructions on multiple data streams

• It processes a single instruction on multiple data streams

• It uses multiple instruction streams on a single data stream
