What does ICMP primarily focus on in networking?
Error checking and reporting
Which element is responsible for defining how data is formatted for transmission over the network?
Access method
What is the main purpose of a MAC address in networking?
To uniquely identify a device on a network
Which device address is determined by the MAC address?
1.1.1.2
How many bytes are typically in a MAC address?
6 bytes
What is the primary function of an IP address in networking?
To identify a specific device on a network
How does a MAC address differ from an IP address?
MAC address is hardware-based, while an IP address is software-based
What is the main advantage of packet-switching in data transmission?
Enables efficient sharing of a single link by multiple packets over time
Which medium uses pulses of light to transmit messages across a network?
Glass or plastic fibers within cables (fiber-optic cable)
What type of cable media uses electrical impulses for communication?
Twisted pair cables
In network transmission, what is the purpose of nodes buffering data?
To equalize data rates across different stations
Which type of cable media is known for its high-speed data transmission capabilities?
Fiber optic cable
What is the key advantage of using wireless transmission as a network medium?
Increased security due to physical cables not being required
What makes fiber optic cables different from twisted pair and coaxial cables in terms of data transmission?
Fiber optic cables can carry data at higher speeds over longer distances
What is the purpose of equalizing data rates among stations connecting to a network?
To ensure smooth flow of data and prevent congestion in the network
Why is line efficiency considered an advantage of packet-switching in data networks?
To share a single link by many packets over time, improving efficiency
Why is speed an important characteristic of fiber optic cables in network communication?
Higher speeds support efficient long-distance data transfer.
