Definition
Hardware refers tothe physical components of a
computer system that you can see and touch.
Examples: CPU, RAM, hard drive/SSD, keyboard, mouse,
monitor, motherboard, etc.

How it works
•Input devices (keyboard, mouse, scanner) send data or
instructions to the computer
• Processing Devices (CPU, GPU, RAM) process the input by
→
following instructions given by software.
• Storage Devices (HDD, SSD, optical disks) save data and
→
programs permanently or temporarily.
• Output Devices (monitor, printer, speakers) show results of
→
processing back to the user.
• Communication Devices (network cards, Wi-Fi adapters) →
allow data exchange between computers.

Advantages
• Advantages ofHardware
• Speed: Modern hardware (fast processors, SSDs, GPUs) makes
computing efficient.
• Reliability: Physical components can consistently perform tasks once
properly set up.
• Upgradability: Hardware can be upgraded (e.g., adding RAM,
replacing a graphics card).
• Storage Capacity: Allows huge amounts of data to be saved and
accessed quickly.
• Variety: Different hardware components can be selected for different
needs (gaming, office work, servers).
5.
Disadvantages
• Cost: High-performancehardware (e.g., gaming PCs,
servers) can be expensive.
• Outdated: Technology becomes outdated quickly as newer
hardware is released.
• Physical Damage: Vulnerable to wear, overheating, and
external damage (dust, power surges, accidents).
• Size/Portability: Powerful systems may be too big
• Dependency: Without compatible software, hardware is
useless.
Conclusion
• Anything thatyou can touch in a computer is hardware
• Input from an input device which sends data to the
computer where it is processed by instructions from the
software
• Output devices show what has been processed
• Efficient, reliable, large store space
• Expensive, easily damaged,
#2 Computer hardware refers to the physical components that make up a computer system, the parts you can see and touch, which enable its functions of input, processing, storage, and output.
Hardware refers to the external and internal devices and equipment that enable you to perform major functions such as input, output, storage, communication, processing, and more.
