Week Two: The Visible Computer 

Our discussion topics for this week is about The Visible Computer (how a PC works, identifying connectors and devices on a typical PC system unit and major components of a PC) and how powerful and affective it has become.

We relied on computers (technologies) for our day-to-day activities and most of all, with the introduced of graphic elements, we can efficiency accomplish tasks of activities in the matter of minutes that was impossible to accomplish using older versions of Windows that used no graphical elements or graphic period.

With that being said, “a modern computer consists of three components” and they are: Hardware, Operation System OS, and Applications.

On the typical PC system unit are variety of connectors and devices that you need for a PC to function properly. Over the years of innovation, many of those connectors and devices have been upgraded to produce power and efficiency and will continued to improve as years goes by. Depending how affective of a PC you want, the following are list of few connectors and devices that come with typical PC system unit:

 USB Ports: used for many output and input devices.

2.      HDMI Port: used for Display connectivity.

3.      S/PDIF: used for high-end audios output.

4.      Audio Input/Output: used for Speakers and Microphones.

5.      NIC: network connection cable (RJ45).

6.      PS/2 or min-DIN: used for mouse connection.

7.      DVI: used for Display connection.

8.      Power Supplies: used for power connector.

 

Some of the major Internal Components of a PC:

The internal components of a Personal Computer PC are:

1.      Central Processing/Processor: the CPU is the brain of the computer, and it is responsible for executing all the information running on the computer. There is an i9 Processor available for all your gamers.

2.      Cache Memory: like RAM, these memories are mounded on the motherboard and are responsibility for “temporarily stores frequently used instruction.”

3.      Random Access Memory (RAM): the responsibility for the RAM is to temporarily store information on the fly that can be accessible later.

All the above components and many more that are listed are what make a computer operate. Regardless of sizes, each of these components played an important role in how well a computer function and it is imperative familiarize these components, as a tech.
