Spend some time exploring the components inside of a computer by performing online research into the topic. You can begin with this link, What does the inside of a computer look like?, and then continue to explore other websites of your own finding to answer the questions below, if needed. How do you think the computer components would change if you were looking at a tablet computer or a smartphone?
What is one major component that would not be found in a tablet or phone, and how has modern computing made that component less important?
What component is in a tablet or phone that wouldn’t have been in a desktop (remember, you can search online for ideas)?

1.         Chassis (case)

Data cable: (IDE, SATA)

Disc drive: CD-ROM, CD-RW, DVD-ROM, or Blu-ray.

Expansion card (ISA, PCI, AGP, and PCI Express).

Fan (Heat sink)

Floppy drive

Hard drive: HDD, SSD

Memory (RAM)

Motherboard

Power cable (Molex)

Power supply (PSU)

Processor (CPU)

The expansion cards are often devices such as your video card, sound card, network card, etc.

It is common for a computer today to have these components built into the motherboard, also referred to as integrated components.

Network card

Sound card

Video card

What parts are needed for a computer to work?

CPU (processor)

Memory (RAM)

Motherboard

Storage device (e.g., hard drive)

2.         Smartphones and tablets have less storage capacity than a computer, and their components cannot be modified like a desktop computer's can. Desktop and laptop computers can run more powerful software than a smartphone or tablet due to their size, components, and less restrictive power requirements.

3. A hard drive

Since tablets and phones are compact, they are better off not having a big, giant, bulky storage device like hard drives. Modern computing made hard drives less important by developing Solid-State Drives (SSDs) and extremely dense (512 bit) storage that can provide the same if not more storage than a traditional hard drive at the fraction of the size.

4.  Since tablets and phones are mobile devices, they would be outfitted with a GPS (Global Positioning System) so that location services would work with them. Desktops do not usually have GPS components.
