Distributed computing concept in Intro to Computing - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is distributed computing?

Distributed computing is a way to connect many computers to work together on a task, sharing the work to finish faster or handle bigger problems.

beginner

Name one real-life example of distributed computing.

The internet is a real-life example where many computers around the world share information and work together to provide services like websites and email.

beginner

Why do distributed systems use multiple computers instead of one?

Using many computers helps handle bigger tasks, improves speed, and keeps the system working even if one computer fails.

intermediate

What is a key challenge in distributed computing?

A key challenge is making sure all computers communicate well and agree on the results, even if some computers are slow or fail.

beginner

Explain distributed computing using a real-world analogy.

Imagine a group of friends building a large puzzle together. Each friend works on a small part, then they combine their pieces to complete the puzzle faster than one person alone.

What is the main goal of distributed computing?

A To slow down processing

B To share work among many computers

C To avoid using computers

D To use only one powerful computer

Distributed computing shares work among many computers to complete tasks faster or handle larger problems.

Which of these is a challenge in distributed computing?

A Making sure all computers agree on results

B Using only one computer

C Avoiding communication between computers

D Ignoring computer failures

Ensuring all computers communicate and agree on results is a key challenge in distributed computing.

In distributed computing, what happens if one computer fails?

A The whole system stops immediately

B The failed computer is ignored forever

C The task is deleted

D Other computers continue working

Distributed systems are designed so other computers continue working even if one fails.

Which real-world system is an example of distributed computing?

A The internet

B A calculator

C A single desktop computer

D A standalone printer

The internet connects many computers worldwide, making it a prime example of distributed computing.

What does distributed computing improve compared to using one computer?

A Only reliability

B Only speed

C Speed and reliability

D Neither speed nor reliability

Distributed computing improves both speed and reliability by sharing work and handling failures.

Describe distributed computing and explain why it is useful.

Think about how many computers can work together like a team.

Give a real-life analogy for distributed computing and explain how it helps understand the concept.

Imagine friends working together on a big task.
