Activity # 1:
Instruction. Please answer the following questions in your own words.
1. What is the difference between architecture of a computer and organization of a
computer?
Ans: Computer Architecture is concerned with the way hardware components
are connected together to form a computer system. Computer Organization is
concerned with the structure and behavior of a computer system as seen by the
user. It acts as the interface between hardware and software.
2. What are five main components of computer? Explain each component.
Ans:
 A motherboard.
 A Central Processing Unit (CPU)
 A Graphics Processing Unit (GPU), also known as a video card.
 Internal Memory (RAM and ROM)
 Storage: Solid State Drive (SSD) or Hard Disk Drive (HDD)
3. Describe the relationships between the different main components of a computer.
Ans:
Motherboard is central to any computer system. Once connected to the motherboard, the
components can work together to form the computer system.
The Central Processing Unit (CPU) is the brain of the computer. The CPU 'controls' what
the computer does and is responsible for performing calculations and data processing. It
also handles the movement of data to and from system memory.
Graphics cards are hardware devices that plug into the motherboard and enables the
computer to display images on the monitor. Graphics cards usually require
the installation of software alongside the hardware. The software instructs the computer
how to use the graphics card and also allows you to alter settings to change image quality
and size.
Internal memory (RAM and ROM)- RAM and ROM are used to store computer data and
this can be directly accessed by the CPU.
RAM is used to temporarily store information that is currently in use by the computer. This
can include anything from word documents to videos.
ROM is used to permanently store instructions that tell the computer how to boot (start
up). It also loads the operating system.
