Description

1. Using your home or work computer, make a rough sketch of the computer's ports. Identify and describe each of the ports on your computer. You are free to hand-draw this sketch, take a photo or scan it and submit it. 

2. In the past, central processing units (CPU) were single core that followed Moore's Law (look that up if you don't know what it is). You may have noticed that the listed speed of a processor has not increased much beyond 4.00 GHz. Instead, CPU's went from single core to multicore to make them faster and while still following Moore's Law. Please answer this research question: Why did CPU's move from single core to a multicore architecture?

The Shift from Single-Core to a Multicore CPU Architecture
Question One
Computer ports

Fig 1: CPU ports (Teva, 2021)
The multicore processor made significant changes and phased out most ports inherent in the
single-core processor. For instance, the AT keyboard port in the single-core processor is notably
replaced with a smaller 6-pin mini-DIN connector. The parallel port, SCSI port, game port, and
serial port are other phased-out ports in the multicore processor that improve functionality and
performance.

Fig 1: PS/2 Connector (Teva, 2021)
IBM developed the port to connect the keyboard and mouse. These connectors are colour-coded
green for the mouse and purple for the keyboard.

Fig 2: COM port (Teva, 2021)
COM port, RS-232 or DE-9 is the key, serial communication port. It enables duplex serial
communication between the computer and its fundamental peripherals.

Fig 3: Parallel port (Teva, 2021)
The parallel port describes an interface between a computer and other devices with distinct
parallel communication. It was established as an interface for peripheral devices...
