Com SCI remark

Thank you sir tom for teaching us these lessons now i understand more about the information stage of the world. I know that i'm lazy but your teachings won't be useless or discarded for the world is already advanced your teachings will change forever our lives and other people.

Installing an OS

To install an Operating Sytem:

     First you should have an installer.(it is best if registered)

System Requirements of the OS :

           Word Size of your Platform

           Processor

           RAM

           Hard Disk

           Graphics Card

Then you should enter the disk/drive then install the OS to your computer if already have an OS you could still install it but it requires additional memory.

Computer system components

These are computer system components

Motherboard (it is called motherboard for all almost all of the components are on the motherboard)

Power Box (this is the voltage regulator of the compute)

RAM (Main Memory)(Random Access Memory)

Processor (CPU)(Central Processing Unit)

Hard Disk (Secondary Memory)(magnetic)

DVD Drive (Optical Drive)

SATA Cables

Video Card (required by some games and videos) 

Network Card

Audio Card

Machine Cycle and Networking

The machine cycle is a basic operation done by the Central Processing Unit, it is also called the processor cycle. It consists of three steps: Fetch. Decode. Execute. For all of this to be done the hardware should be in good condition

A network is a group of two or more computers connected to each other. Internet meaning a inter connection of network.

These are some types of NETWORKS:

          LAN - Local Area Network

         MAN - Metropolitan Area Network

         WAN - Wide Area Network

Also these networks have their own properties although they are transmitted as radio waves.

Computer Hardware Troubleshooting

Computer Hardware Troubleshooting

                 - is to diagnose the hardware of the computer if there are problems such as your audio doesn't work because of the wrong software.

                 It is easier said than done if your a beginner if you are a computer Scientist teacher like our teacher it would be easy as reciting ABC but for us it is not that easy but not that very hard for simple problems only.
