Hardware Part 1 And 2

ROM stands for Read Only Memory and is nonvolatile. ROM is a type of computer memory that is pre-programmed during manufacturing and cannot be modified or erased by normal computer operations. It contains permanent data or instructions that are essential for the computer's basic functions. Unlike volatile memory, which loses its data when the power is turned off, ROM retains its contents even when the power is off, making it nonvolatile.

RAM is volatile, meaning it doesn't persist after the power is turned off. Volatile refers to the temporary nature of RAM, as it requires continuous power supply to retain data. Once the power is turned off, the data stored in RAM is lost. Unlike non-volatile memory such as hard drives or solid-state drives, RAM is used for temporary storage and is not designed to retain data in the long term.

The correct answer is "Network card" because the question is asking to check the internal device inside the case, and out of the given options, the network card is the only device that is typically located inside the computer case. The monitor and keyboard are external devices that are connected to the computer but are not inside the case.

eSATA is a fast external connection specifically designed for hard drives. It allows for high-speed data transfer between the computer and the external hard drive, making it ideal for tasks that require large file transfers or high-performance storage solutions. Unlike other connections mentioned, such as network cards or CPUs, eSATA is solely focused on providing a fast and reliable connection for external hard drives.

The northbridge chipset is responsible for controlling the flow of data between the CPU, RAM, and the graphics card (video). It acts as a bridge connecting these components and facilitates the exchange of information. Therefore, the statement is true.

The correct answer is audio because audio components are responsible for controlling all the input or output of sound for the computer. This includes features such as speakers, microphones, and sound cards. The CPU is responsible for executing instructions and performing calculations, the chipset is responsible for controlling communication between the CPU and other components, and RAM is responsible for storing data that the computer is actively using. Therefore, audio is the most appropriate answer for this question.

Intel is the world's largest processor manufacturer. They have a dominant market share and are known for their high-performance processors that are widely used in computers and other electronic devices. Intel's processors are known for their reliability, efficiency, and advanced technology, making them the preferred choice for many consumers and businesses.

The southbridge chipset is responsible for handling the input and output ports of a computer. It acts as the IO (Input/Output) controller, facilitating communication between the computer's processor and various peripheral devices such as USB ports, audio jacks, and storage devices. This allows data to be transferred to and from these devices, enabling the computer to interact with the external world. Therefore, the statement is true.

Secondary storage refers to the long-term storage of data that is not currently being used by the computer. It is used to store data permanently, even when the computer is turned off. Unlike RAM, which is volatile and loses its data when the power is turned off, secondary storage devices like hard drives, solid-state drives, and optical discs retain data even when not powered. Therefore, the correct answer is "permanent."

Random Access Memory (RAM) is temporary storage because it is used to store data that is currently being accessed or used by the computer. Unlike permanent storage such as hard drives or solid-state drives, RAM does not retain its data when the computer is turned off or restarted. Instead, it is volatile memory that is constantly being read from and written to by the computer's processor. This allows for quick and efficient access to data, but it also means that any data stored in RAM is lost when the power is cut off. Therefore, RAM is considered temporary storage.

Primary storage refers to the main memory of a computer system, which is used to store data and instructions that are currently being processed by the CPU. It is also known as RAM (Random Access Memory). The term "temporary" accurately describes primary storage because the data stored in RAM is volatile and is lost when the computer is turned off or restarted. Therefore, primary storage is not a permanent storage solution like a hard drive or DVD-ROM, which can retain data even when the power is turned off.
