Unit 3 - Networks part 1

What is a network in the context of computer systems?

• A single computer system designed for one user

• A number of computer systems connected together

• A standalone software application

• A type of computer hardware

Which of the following is an advantage of a network?

• Slower data transfer

• Increased risk of data loss

• Centralised backup

• Higher costs for maintenance

What does centralized maintenance in a network allow?

• Decreased network performance

• Managing the network from multiple locations

• Managing the network from one location

• Less control over the network resources

How does a network make it easier for internal communication?

• By allowing only external communication

• By making communication more complex

• By enabling the sending of emails

• By disconnecting computer systems

What might be a consequence of not having a properly secured network?

• Increased productivity

• Security problems such as viruses spreading

• Faster data processing

• Reduced costs

What can happen if a server goes down in a networked environment?

• Only the server is affected

• All workstations on the network are unaffected

• All workstations on the network are affected

• Internet speed increases

Why might a network manager be necessary in a networked environment?

• To reduce the overall cost

• To increase security risks

• To manage and maintain the network

• To decrease efficiency

What is a potential downside of the initial setup of a network in terms of cost?

• There is no initial cost

• Initial cost is always low

• Initial cost of servers and communication devices can be expensive

• Initial cost includes free maintenance

How can hackers impact a network?

• They can slow down the network

• They can improve network security

• They can gain access to data more easily

• They can provide free technical support

What is required to connect a computer to a network?

• A Network Interface Card (NIC)

• A Universal Serial Bus (USB) cable

• A High-Definition Multimedia Interface (HDMI) cable

• A Central Processing Unit (CPU)
