CS CHAPTER 2, 7,8

What is a data packet? -kuc

• Data packets are random bits of information without structure.
• Data packets are physical devices for data storage.
• Data packets are formatted units of data for network transmission.
• Data packets are only used in wireless communication.

3 sections of packets are packet header, .............., and ............. .-kuc

• paysource,trailer

• sender, receiver's address

• payload, trailer
• packetload, trailer

What is a payload? -kuc

• A payload refers to the physical weight of a package.
• In programming, a payload is a type of error message.
• The payload is the header information in a packet.
• In computing, a payload is the actual data transmitted in a packet.

What is the difference between serial and parallel data transmission?-kuc

• Serial transmission is faster than parallel transmission.
• Parallel transmission sends data one bit at a time, while serial send multiple bits simultaneously.

• Serial transmission sends data one bit at a time, while parallel transmission sends multiple bits simultaneously.
• Serial transmission requires more wires than parallel transmission.

What type of data transmission is this?-ac

• serial

• half-duplex

• parallel

• full-duplex

What is a full duplex data transmission?-kuc

• Full duplex allows data to be sent and received at the same time..

• Full duplex data transmission requires a physical connection for each direction.
• Half duplex data transmission allows data to be sent in one direction only.
• Full duplex data transmission is slower than half duplex transmission.

What type of data transmission is this?-ac

• Full-duplex transmission

• Simplex transmission
• Parallel transmission

• Half-duplex transmission

What is the advantage of using USB?-kuc

• USB is only compatible with Windows devices.
• USB ports are not widely available on modern devices.
• USB allows devices to be plugged in or removed without turning off the computer.

• USB connections are slower than serial connections.

What does USB stands for? -ct

• Universal Serial Connection

• Unified Serial Bus
• Universal System Bus
• Universal Serial Bus

What is parity check?-kuc

• A method for error detection in digital data transmission using a parity bit.
• A technique for data compression in digital storage.
• A process for encrypting digital information.
• A method for increasing data transmission speed.
