What is computer science and engineering?
Computer science is the study of the theoretical foundations of information and computation, and of their application in engineering. Engineering is the application of scientific and mathematical principles to the design, development, and operation of structures, machines, and systems.
What is the difference between computer science and engineering?
Computer science is the study of the theoretical foundations of information and computation, whereas engineering is the application of computer science principles and techniques to solve real-world problems.
What is computer science?
Computer science is the study of the theoretical and practical aspects of computing. It is the systematic study of the feasibility, design, implementation, and maintenance of software systems.
What is engineering?
Engineering is the application of scientific and mathematical principles to practical ends such as the design, manufacture, and operation of engines and machines.
What is the internet of things?
The internet of things (IoT) is the network of physical objects or “things” embedded with electronics, software, sensors, and network connectivity that enables these objects to collect and exchange data.
What is a sensor?

What is a gateway?
A gateway is a device that allows two or more separate networks to communicate with each other. Gateways can be used to connect LANs to WANs, or to connect different types of networks together.
What is a protocol stack?
A protocol stack is a set of networking protocols that work together to transmit data between two devices. The protocols in a stack are usually arranged in order of importance, with the most important protocol at the top and the least important protocol at the bottom.
What is a bus?
A bus is a vehicle that transports people.
What is a hub?
A hub is a device that forwards packets between networks. When a packet arrives at a hub, the hub examines the destination address and determines which port the packet should be forwarded to.
What is a switch?
A switch is a device that is used to connect and disconnect electrical devices.
What is a router?
A router is a network device that forwards data packets between computer networks. Routers are located at gateways, the borders of networks.
What are the basic components of a computer?
The basic components of a computer are a monitor, keyboard, mouse, and CPU.
What is a microprocessor?
A microprocessor is a computer chip that contains the circuitry to control the entire computer.
What is a motherboard?
A motherboard is a printed circuit board that serves as the main circuit board for a computer. It holds many of the computer’s essential components, such as the central processing unit, memory, and the bus.
What is a memory module?
A computer memory module is a circuit board that holds memory chips.
What is a hard drive?
A hard drive is a device used to store digital information, such as photos, music, and videos.
What is a CD-ROM?
A CD-ROM is a type of optical disc that can store digital data. It is a predecessor to the more common DVD-ROM.
What is an operating system?
