Chapter 1B Hardware: Lets take a look inside

Ever wondered whats inside the computer?: Well lets take a Glimpse

• Motherboard- the biggest component in the computer.
• Hard Drive And Optical Drive- this is wear your permanent storage takes place
• Power supply- The power house of the computer. This is wear all devices get there power
• Adapter cards- Communicate with devices inside and out the case

Here is a briefing on what goes on inside

ADAPTER CARDS (EXPANSION CARDS) ARE INSTALLED IN Long narrow expansion slots on the motherboard. All adapter cards
contain microchips which are most often manufactured using complementary metal oxide semiconductor...(cmos)
There are two types of cables inside the case
data cables- connect devices to one another
power cables- which supply power
flat cable is more than likely a data cable---trace to be sure

MOTHER BOARD

contains a socket to hold the Central Processing Unit (CPU)
Motherboard is complicated equipment. All devices must communicate with the CPU installed on the motherboard.
A device that is not directly installed on the motherboard is a PERIPHERAL DEVICE.
CHIPSET SUPPORTS THE PROCESSOR BY CONTROLLING MOTHERBOARD ACTIVITIES

Hardware VS Software

Hardware is physical. Your mouse. Your computer screen. Your Printer. This is all harware.

Software is the insructions that get your harware to do the work. The computer uses hardware for four basic taks. Input, Output, Processing and Storage.

The computer is pretty much stupid. The only way to get it to work is if we break everything down.  This is where software comes in. Software converts instructions for the physical components (hardware).  This is done by two simple commands. On AND off.

On & Off
It sounds coplicated right. But its not. On & Off translated 1 & 0 to a computer. In computer programming. 1 is the presence of Voltage. 0 is the lack of Voltage. Now remember voltage is an elctromotive force. Simply meaning that 1 and 0's controls a computers actions altogether.

0 & 1

The technology of storing and reading only two states is called binary. The number system that uses two states is called, binary number system. Think of it as when you was taught to count.( 1, 2, 3, 4, 5 etc). That is how humans understand counting. The computer is taught to understand it in two forms. 1 and 0.

Grouping in the binary system is done in eights. 1 digit equa1s a bit. 8  digits equals a byte. 8 bits equal a byte.  A computers calculations and counting uses the binary number system. Counting for a computer (binary code) goes simply like this. 0, 1, 10, 11, 100, 101 and so on. Thats how the computer counts, talks, reads, and everything.

When text is stored into a computer it is stored using 0's and 1's. For example the letter A is 0100 0001.

All letters and numbers are stored in a computer as a series of bits each represented in the computer as on and off.

Concluding how software works with hardware.
