Hardware includes ..........
A. all devices used to input data into a computer.
B. sets of instructions that a computer runs or executes.
C. the computer and all the devices connected to it that are used to input and output data.
D. all devices involved in processing information including the central processing unit, memory and storage.
E. None of these
Answer: Option D
Solution(By Examveda Team)
Hardware encompasses all the physical components of a computer system. This includes the central processing unit (CPU), memory (RAM), storage devices (e.g., hard drives, SSDs), input devices (e.g., keyboard, mouse), output devices (e.g., monitor, printer), and any other physical components that are involved in processing and managing data. Hardware is the tangible, physical part of a computer system, as opposed to software which consists of programs and instructions.
The other options are not entirely correct:
Option A: all devices used to input data into a computer. While it is a part of hardware, hardware includes more than just input devices.
Option B: sets of instructions that a computer runs or executes. This describes software, not hardware.
Option C: the computer and all the devices connected to it that are used to input and output data. This is partially correct but doesn't encompass all hardware components involved in processing information.
Option E: None of these is not accurate because Option D is the correct answer, as it includes all hardware components.
So, the correct answer is Option D: all devices involved in processing information including the central processing unit, memory, and storage.

i asked chatGpt it answered D as well...heres why:
Memory and storage are two fundamental hardware components in a computer, and they serve different purposes. It's common for people to confuse the two because they both involve storing data, but they do so in distinct ways and with different characteristics. Here's a clear explanation of memory and storage hardware:
**Memory (RAM - Random Access Memory):**
1. **Purpose**: RAM is the computer's primary memory, and its main purpose is to provide fast, temporary storage for data that is actively being used by the computer's processor (CPU).
2. **Speed**: RAM is very fast and allows the CPU to access data quickly. It provides the "working memory" for the computer.
3. **Volatility**: RAM is volatile, which means it loses all its data when the computer is turned off or restarted. It's intended for temporary storage.
4. **Capacity**: RAM capacity is relatively limited compared to storage devices. A typical computer might have 8 GB, 16 GB, or more of RAM.
In essence, RAM is like the computer's short-term memory. It's used to hold data and programs while they are actively in use. When the computer is powered off, all the data in RAM is erased.
**Storage (Hard Drives, SSDs, etc.):**
1. **Purpose**: Storage devices are used for long-term data storage. They hold data even when the computer is turned off and are intended for more permanent storage of files and programs.
2. **Speed**: While storage devices have improved in speed with technologies like SSDs (Solid-State Drives), they are significantly slower than RAM. Accessing data from storage is not as fast as accessing data from RAM.
3. **Non-Volatility**: Storage is non-volatile, meaning it retains data even when the computer is turned off. It is used for persistent, long-term storage.
4. **Capacity**: Storage devices offer much larger capacity compared to RAM. You can have terabytes of storage on a typical hard drive or SSD.
Storage is like the computer's long-term memory. It's where you store your operating system, applications, documents, photos, videos, and all other data you want to keep for the long haul.
In summary, memory (RAM) is fast but volatile, used for temporary data storage, while storage (hard drives, SSDs) is slower but non-volatile and used for long-term data storage. They complement each other in a computer system, with RAM providing the workspace for actively running programs, and storage serving as the place to store your files and data permanently.
HOW ARE MEMORY AND STORAGE HARDWARE DEVICES???
i think c is correct answer
i think c should be the correct answer
