Hard drive The hard drive will store data when the computer is turned off but may lose data.

Contains peripheral devices used for input, output, and long-term storage

I/O Subsystem

Identify components of computer hardware.

In the case of hardware there are a multitude of components that, when combined and each performing their individual task, make up what we think of as a computer or hardware. This can include the CPU, memory chips, storage devices, keyboards and printers, among others. The CPU is the central processing unit of the computer which is responsible for executing instructions and managing other computer components. The CPU is the central processing unit of the computer which is responsible for executing instructions and managing other computer components. The CPU is the central processing unit of the computer which is responsible for executing instructions and managing other computer components. The Bus can have many wires, cables, or printed circuits that can transmit bits of information. These bits can be combined to create more complex data.

Stores programs being executed and data that the programs use

Memory

Which peripheral device that was previously only an output device became both an input and output device with the advent of the tablet computer?

Monitor Correct. The screen of a tablet is used for output and input (touch).

Which input peripherals are now integrated in the laptop?

Mouse, keyboard, and webcam

Hard Drive

Nonvolatile Correct. The purpose of a hard drive is to store data even when the computer is turned off. However, hard drives can develop problems involving the loss of data and should therefore be backed up.

Differentiate between motherboard components, their purposes, and properties.

ROM holds the instructions the computer needs to boot up. RAM information disappears when the computer is turned off. RAM and ROM both store programs. When you purchase a computer, you can opt to include additional RAM. RAM and ROM both store information as bits. RAM is the temporary form of memory. RAM temporarily stores data before it is processed and sent to your screen or printer. RAM storage is in the 1-8 GB range RAM memory temporarily stores the information needed by programs to run. Dynamic RAM (DRAM) is also called main memory, and static (SRAM) is also called cache memory. These are the two main forms of RAM. RAM can be read and written to. BIOS ROM is stored in the ROM chip on the motherboard. The hard drive will store data when the computer is turned off but may lose data. RAM memory never stores data when the ROM memory is a form of permanent storage for instructions that the computer needs to boot up or start.power is off and is designed to be the primary work area of a computer when data is being processed. The purpose of a hard drive is to store data even when the computer is turned off. However, hard drives can develop problems involving the loss of data and should therefore be backed up.

RAM computer memory is involved in the following:

Running programs

motherboard

The motherboard or system board directly or indirectly connects all other components and peripherals of the computer.

Indicate which of the following is an accurate statement about the CPU.

The CPU interprets and executes programs.

Which of the following statements best describes the function of the CPU?

The CPU processes programs.

CU

The CU retrieves the instructions and raw input data and sends that data for processing.

Which of the following best describes the I/O subsystem?

The I/O subsystem includes devices such as the printer, keyboard, and monitor.

Which of the following best describes the function of the bus component?

The bus transfers information between computer components or between computers.

Describe the role of a central processing unit (CPU) in a computing environment.

The central processing unit (CPU) or processor is the component in a computer that executes programs.

hard drive

The hard drive allows for long-term storage and data can be saved on the hard drive so when the computer boots, the data is readily available to the user.

hard drive

The hard drive is an electronic component used to store instructions, programs, data, and information for future use.

Motherboard

The motherboard is a thin, flat piece of circuit board, usually green or gold, that directly or indirectly connects all other components and peripherals.

Differentiate between motherboard components, their purposes, and properties.

The motherboard is a thin, flat piece of circuit board, usually green or gold, that directly or indirectly connects all other components and peripherals. The central processing unit (CPU) or processor is the component in a computer that executes programs. The memory module is attached to the motherboard and consists of electronic components that store instructions and data. The input/output connections are used to connect peripheral devices such as a monitor, speakers, projector, etc. The heat sink ensures that the CPU does not overheat and the fan keeps the heat sink cool so it does not overheat.
