AP CSP Vocab Review Unit 2

What is a machine that can run a program, including computers, tablets, servers, routers, and smart sensors?

• Computing System

• Computing Device

• Router

• Internet

Answer explanation

A computing device is any machine that can run programs, including computers, tablets, servers, routers, and smart sensors. Therefore, the correct answer is 'Computing Device'.

What term describes a group of computing devices and programs working together for a common purpose?

• Computing Network

• Protocol

• Computing System

• Bandwidth

Answer explanation

A 'Computing System' refers to a group of computing devices and programs that work together to achieve a common goal, making it the correct choice. Other options like 'Computing Network' and 'Protocol' do not fully capture this concept.

What is a group of interconnected computing devices capable of sending or receiving data?

• Computing Network

• Physical Network

• Internet

• World Wide Web

Answer explanation

A computing network is a group of interconnected devices that can send and receive data. While the Internet and World Wide Web are larger systems, the term 'computing network' specifically describes the interconnected devices.

What term refers to the series of connections between computing devices on a network starting with a sender and ending with a receiver?

• Path

• Packet

• Router

• Redundancy

Answer explanation

The term 'Path' refers to the series of connections that data travels through from the sender to the receiver in a network. It represents the route taken by packets of data, making it the correct choice.

What is the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second?

• Bandwidth

• Redundancy

• Fault Tolerant

• Packet

Answer explanation

The maximum amount of data that can be sent in a fixed time is referred to as bandwidth. It is measured in bits per second and indicates the capacity of a network connection.

What is an agreed-upon set of rules that specify the behavior of some system?

• Protocol

• IP Address

• DNS

• HTTP

Answer explanation

A protocol is an agreed-upon set of rules that defines how data is transmitted and received in a system. It ensures proper communication between devices, making 'Protocol' the correct answer.

What is the unique number assigned to each device on the Internet?

• IP Address

• TCP

• UDP

• DNS

Answer explanation

The unique number assigned to each device on the Internet is called an IP Address. It identifies devices and allows them to communicate over the network, unlike TCP, UDP, and DNS, which are protocols and services.

What protocol is used for sending data across the Internet that assigns unique numbers to each connected device?

• IP: Internet Protocol

• HTTP

• DNS

• TCP

Answer explanation

The Internet Protocol (IP) is responsible for assigning unique addresses to devices on the Internet, enabling data transmission between them. Other options like HTTP, DNS, and TCP serve different functions in networking.

What protocol breaks messages into packets and ensures reliable delivery by checking for errors and reordering packets?

• TCP: Transmission Control Protocol

• UDP: User Datagram Protocol

• HTTP

• DNS

Answer explanation

TCP (Transmission Control Protocol) breaks messages into packets, ensures reliable delivery by checking for errors, and reorders packets as needed. This makes it suitable for applications requiring data integrity.

What protocol is used for sending data without ensuring reliable delivery?

• UDP: User Datagram Protocol

• TCP: Transmission Control Protocol

• HTTP

• DNS

Answer explanation

UDP (User Datagram Protocol) is used for sending data without ensuring reliable delivery, making it suitable for applications like video streaming and online gaming where speed is prioritized over reliability.
