Question

answer all of the questions below in 3 - 4 sentences.

1. define the term \computer hardware\ and give one example.
2. what is the main function of the cpu in a computer system?
3. explain the difference between ram and a hard drive or ssd in terms of how they store data.
4. what does the term \clock speed\ mean when describing a cpu?
5. name two common types of internal storage devices and identify which one is typically faster.

Explanation:

1. Computer hardware refers to the physical components of a computer system. These are tangible parts that can be seen and touched. For example, the central processing unit (CPU) is a crucial hardware component that performs most of the processing inside a computer.
2. The main function of the CPU (Central Processing Unit) in a computer system is to execute instructions. It acts as the brain of the computer, performing calculations, logical operations, and controlling the flow of data within the system.
3. RAM (Random - Access Memory) stores data temporarily while the computer is running. It allows the CPU to access data quickly for immediate use. In contrast, a hard drive or SSD (Solid - State Drive) stores data permanently. RAM is volatile (loses data when power is off), while hard drives/SSDs are non - volatile.
4. Clock speed, when describing a CPU, refers to the number of cycles per second that the CPU can execute. It is measured in gigahertz (GHz). A higher clock speed generally means the CPU can process instructions faster.
5. Two common types of internal storage devices are hard drives (HDDs) and solid - state drives (SSDs). SSDs are typically faster than HDDs because they have no moving parts, allowing for quicker data access and transfer.

Answer:

1. Computer hardware is the physical parts of a computer. Example: CPU.
2. The CPU executes instructions and acts as the computer's brain.
3. RAM is temporary, volatile storage; HDD/SSD is permanent, non - volatile.
4. Clock speed is the CPU's cycles per second (GHz), higher means faster processing.
5. HDD and SSD; SSD is faster.
