What is the device name that connects computers?
Options:
BIOS
Modem
Port
Power supply(Choose the right answer from the options and type it exactly the same.)
Explanation
A modem is a device that connects computers to the internet or other networks. It converts digital signals from the computer into analog signals that can be transmitted over telephone lines or other communication channels. By doing so, it allows computers to communicate with each other and access information from remote servers. Therefore, a modem is the correct device name that connects computers.
2.
What is known as a computer's microprocessor?Options: BIOSModemPortPower supply(Choose the right answer from the options and type it exactly the same.)
Explanation
The microprocessor is the central processing unit (CPU) of a computer, responsible for executing instructions and performing calculations. The BIOS (Basic Input/Output System) is a firmware that is stored on a chip on the motherboard and is responsible for initializing the hardware components of the computer, including the microprocessor, when the computer is powered on. Therefore, the correct answer is BIOS.
3.
What is known as the brain of the computer?Options: USB portModemCPUMouse(Choose the right answer from the options and type it exactly the same.)
Explanation
The CPU, or Central Processing Unit, is known as the brain of the computer. It is responsible for executing instructions, performing calculations, and managing the flow of data within the computer system. The CPU is the primary component that carries out the majority of the computer's processing tasks, making it a critical part of the computer's functionality.
4.
What is the memory of the computer?Options: BIOSUSBPortROM(Choose the right answer from the options and type it exactly the same.)
Explanation
ROM stands for Read-Only Memory. It is a type of computer memory that stores data permanently and cannot be modified or erased. The data stored in ROM remains intact even when the computer is turned off. It contains the firmware or software instructions that are essential for the computer to start up and perform basic functions. Therefore, ROM plays a critical role in the operation of a computer system by providing the necessary instructions for the hardware and software components to function properly.
5.
What contains data in the computer?
Options:
Hard drive
Modem
Power supply
Video card
(Choose the right answer from the options and type it exactly the same.)
Explanation
The hard drive is a storage device in a computer that contains data. It is used to store and retrieve digital information, including operating systems, software programs, and user files. The hard drive uses magnetic storage to store data on rotating disks called platters. It provides long-term storage for the computer and allows for quick access to data when needed.
6.
What can read and write data in the computer?Options: Hard driveModemRAMVideo card(Choose the right answer from the options and type it exactly the same.)
Explanation
RAM (Random Access Memory) is a type of computer memory that can both read and write data. It is a volatile memory, meaning that its contents are lost when the computer is powered off. RAM is responsible for temporarily storing data that the computer needs to access quickly, such as program instructions and data being actively used by the operating system and applications. It allows for quick and efficient data retrieval and manipulation, making it essential for the smooth functioning of a computer system.
7.
What holds and keeps all of the other circuit boards?
Options:
Motherboard
Webcam
RAM
Video card
(Choose the right answer from the options and type it exactly the same.)
Explanation
The motherboard is the main circuit board in a computer that holds and connects all of the other circuit boards and components. It provides the electrical connections and pathways for data to flow between the different parts of the computer. Without the motherboard, the other circuit boards would not have a way to be connected and function properly.
8.
What supplies power to the computer?
Options:
Webcam
Graphic card
Power supply
Video card
(Choose the right answer from the options and type it exactly the same.)
Explanation
The power supply is responsible for supplying power to the computer. It converts the AC power from the wall outlet into DC power that the computer components can use. Without a power supply, the computer would not be able to function. The other options listed (webcam, graphic card, video card) are all components of the computer, but they do not directly supply power to the system.
9.
What handles the graphics displayed on the monitor?
Options:
Port
Video card
Power supply
Motherboard
(Choose the right answer from the options and type it exactly the same.)
Explanation
The video card is responsible for handling the graphics displayed on the monitor. It is a hardware component that generates and outputs the visual information to the monitor. The video card processes the data from the computer's CPU and converts it into a format that can be displayed on the monitor. It also has its own memory to store and process the graphics data, allowing for smooth and high-quality visuals on the screen.
10.
What are other hardwares like the keyboard or monitor plugged into?
Options:
Port
ROM
Motherboard
CD ROM
(Choose the right answer from the options and type it exactly the same.)
Explanation
Other hardware devices like the keyboard or monitor are typically plugged into a port. A port is a connection point on a computer or device where peripheral devices can be attached. It allows for communication and data transfer between the computer and the peripheral devices.
