WHAT COMPONENTS ARE INSIDE MY COMPUTER?

This video is about what components are inside a computer and how they work together. It is very useful to recognize them and know their function.

You can watch it and revise hardware lessons which we have learned during this term. We think this video will be really helpful for your next exam.

You can also read the transciption after watching the video.

1. Step 1: The Major Components

   The major components of a computer are:
   
   The Motherboard
   
   The CPU or Central Processing Unit
   
   RAM or the Random Access Memory
   
   The Graphics Card
   
   The Power Supply
   
   The Hard Disk or Hard Drive
   
   The Optical Drive - also known as a CD or DVD Drive

2. Step 2: Hardware and Software

   All of these components are usually found within the tower of a desktop computer. They are referred to as "hardware". Hardware can be thought of as the actual physical components that go into the computer. "Software" refers to the programs and systems that operate within the hardware.

3. Step 3: The Motherboard

   The motherboard is the “heart” of the computer. It is the largest and most fundamental component of a PC and every other component is attached to it in some way. This is because all the different components use the motherboard to communicate and work with each other.
   
   The motherboard has a series of slots, sockets and connectors for attaching the components of a PC.
   In most cases, the memory, accessory cards, and CPU are installed directly onto the motherboard. The drives and peripherals communicate with the motherboard through wired connections.
   
   There are a wide range of motherboards to choose from. They differ in features, speed, capacity and the CPU supported. They also differ in size, shape and layout, this is commonly referred to as the "form factor"

4. Step 4: The CPU

   CPU stands for Central Processing Unit. This is the brain of the computer and is often referred to as the "processor" or the "chip". It is found under a heat sink and fan and sits directly on the motherboard.
   
   The CPU directs, coordinates and communicates with the other components and performs all of the "thinking". It's not really thinking, what a CPU actually does is perform mathematical calculations. It is the software that people write that translates those calculations into useful functions for us.

5. Step 5: RAM

   RAM stands for Random Access Memory, and comes as modules in predefined amounts. It is also found directly on the motherboard and usually in one, two or four slots. The memory chips store information, temporarily, for short term use by the CPU. RAM is used to store information for files that are actually being used by the CPU at any given time.
   
   The computer's RAM memory is an entirely different thing from the hard disk "memory". The hard disk stores information "permanently" for long term use.

6. Step 6: The Graphics Card

   The graphics card or video card translates information into the graphics and text that appear on the monitor screen.
   Most motherboards now include a slot specifically designed for the graphics adapter called the AGP slot. This stands for Advanced Graphics Port.
   Modern graphics adapters usually incorporate some memory right on the card to improve their performance.

7. Step 7: The Power Supply

   This supplies power to the other components, which is why it has so many wires coming out of it.
   It is usually positioned at the back top corner of the computer case. The power supply has a fan built into it to keep itself and the computer cool.

8. Step 8: The Hard Disk

   A hard disk - which is also called a "hard drive" - is much like a filing cabinet. The programs and data are stored on the hard disk and the computer accesses them as they are needed. When the computer accesses the hard drive, it is reading and moving the stored information into the RAM memory. That memory is the temporary workspace. However, the original file is still on the hard disk and is left undisturbed until the file is saved.
   
   When the computer stores or "saves" information, it writes the data to the hard disk. That process results in the old file being replaced or modified with the new information. If you save data to a new file, or install new software, the information is written to the disk in an available, unused portion of the disk.

9. Step 9: The Optical Drive

   The optical drive is often called a DVD drive, or a CD drive. It sits at the front of the computer for ease of access, and uses a laser to read and write information to CD's and DVD's.

TECHNOLOGY PROJECTS

During the last month, our bilingual students have been creating a project related to all the contents we have been studiyng so far. First we divided them into different groups. Then they started to carry out all the tasks. After finishing their projects they presented them to the rest of the class.

Here you can see some videos and pictures about these projects.

SERIES AND PARALLEL CIRCUITS

Here we have a video about the series and parallel connection in circuits. Watch it and answer these questions in your notebook. Remember that you should write down the headings.

• What is the tension that is applied to the circuit?
• Regarding the circuit in series connection, what voltage will each electric bulb receive?
• What happens if an electric bulb which is connected in series to other electric bulbs breaks down?

• Regarding the circuit in parallel connection, what voltage will each electric bulb receive ?
• What happens if an electric bulb which is connected in parallel to other electric bulbs breaks down?

Eventually, go to comments and leave your opinion about the advantages and disavantages of series and parallel connection. Don´t forget to write down your name!
