Common Mistakes

Confusing client with server

Thinking peers provide services in client-server

💡 Hint

Common Mistakes

Choosing network devices like router or switch instead of server

In peer-to-peer networks, each computer can both request and provide resources, acting as both client and server.

💡 Hint

Common Mistakes

Thinking clients send or provide resources to servers

Clients request resources from servers; they do not send or provide resources to servers.

4fill in blank

Fill both blanks to complete the peer-to-peer network description.

Computer Networks

In peer-to-peer networks, computers [1] resources directly and there is no [2] computer.

💡 Hint

Common Mistakes

Choosing 'control' instead of 'central' for the second blank

Peer-to-peer computers share resources directly without a central computer controlling the network.

5fill in blank

hard

Fill all three blanks to describe differences between client-server and peer-to-peer models.

Computer Networks

Client-server networks have a [1] server, clients [2] resources, and peer-to-peer networks have [3] computers sharing resources equally.

💡 Hint

Common Mistakes

Mixing up 'single' and 'multiple' for servers

Confusing who requests resources

Client-server networks have a central server; clients request resources. Peer-to-peer networks have multiple computers sharing resources equally.

Practice

1. Which statement best describes the client-server model in networking?

easy

A. A central server manages communication between clients.

B. All devices share resources equally without a central server.

C. Devices connect randomly without any control.

D. Clients communicate only through peer devices.

Solution

1. Step 1: Understand the client-server model

   In this model, a central server controls communication and resource sharing.

2. Step 2: Compare with other models

   Unlike peer-to-peer, clients depend on the server for services.

3. Final Answer:

   A central server manages communication between clients. -> Option A

4. Quick Check:

   Client-server = Central server control [OK]

Hint: Client-server means one main server controls all [OK]

Common Mistakes:

• Confusing peer-to-peer with client-server
• Thinking clients communicate directly without server
• Assuming no central control in client-server

2. Which of the following correctly represents a peer-to-peer network?

easy

A. A single server provides resources to multiple clients.

B. Clients request data only from a central server.

C. Each device can act as both client and server.

D. Devices are connected through a router only.

Solution

1. Step 1: Identify peer-to-peer characteristics

   In peer-to-peer, devices share resources equally and can act as both client and server.

2. Step 2: Eliminate incorrect options

   Options A and B describe client-server, and D is unrelated to network model type.

3. Final Answer:

   Each device can act as both client and server. -> Option C

4. Quick Check:

   Peer-to-peer = Devices share equally [OK]

Hint: Peer-to-peer means all devices share roles equally [OK]

Common Mistakes:

• Thinking only servers provide resources
• Confusing router connection with network model
• Assuming peer-to-peer needs a central server

3. Consider a file-sharing application where every computer can upload and download files directly from others without a central server. What network model does this describe?

medium

A. Peer-to-peer model

B. Client-server model

C. Hybrid model

D. Cloud computing model

Solution

1. Step 1: Analyze the file-sharing setup

   Every computer uploads and downloads directly without a central server.

2. Step 2: Match with network models

   This matches the peer-to-peer model where devices share equally without a server.

3. Final Answer:

   Peer-to-peer model -> Option A

4. Quick Check:

   Direct sharing without server = Peer-to-peer [OK]

Hint: Direct sharing without server means peer-to-peer [OK]

Common Mistakes:

• Choosing client-server because of file sharing
• Confusing hybrid with peer-to-peer
• Assuming cloud model applies here

4. A network administrator sets up a system where all devices connect to a central server, but some devices also share files directly with each other. What is the issue with calling this a pure client-server model?

medium

A. Devices cannot connect to more than one network.

B. Central servers cannot handle multiple clients.

C. Peer-to-peer networks require a central server.

D. Client-server model does not allow direct device-to-device sharing.

Solution

1. Step 1: Understand client-server model rules

   In client-server, clients communicate only through the central server, no direct sharing.

2. Step 2: Identify the problem

   Direct device-to-device sharing contradicts pure client-server model.

3. Final Answer:

   Client-server model does not allow direct device-to-device sharing. -> Option D

4. Quick Check:

   Direct sharing ≠ pure client-server [OK]

Hint: Client-server means no direct sharing between clients [OK]

Common Mistakes:

• Thinking central server can't handle many clients
• Confusing peer-to-peer needs server
• Believing devices can't join multiple networks

5. You want to design a small office network where all employees can share files directly without relying on a central server, but also want to add a server later for backups. Which model should you start with and why?

hard

A. Start with client-server for centralized control, then add peer-to-peer features.

B. Start with peer-to-peer for direct sharing, then add a server for backups.

C. Use only client-server because peer-to-peer is insecure.

D. Use only peer-to-peer because servers are unnecessary.

Solution

1. Step 1: Analyze the requirement for direct sharing

   Direct sharing without a server fits peer-to-peer model initially.

2. Step 2: Consider adding a server later

   Adding a server later for backups is possible in peer-to-peer networks, creating a hybrid setup.

3. Final Answer:

   Start with peer-to-peer for direct sharing, then add a server for backups. -> Option B

4. Quick Check:

   Direct sharing first = Peer-to-peer start [OK]

Hint: Start peer-to-peer for sharing, add server later for backups [OK]

Common Mistakes:

• Starting with client-server when direct sharing needed
• Ignoring hybrid network possibilities
• Assuming peer-to-peer can't add servers
