Computer Data
Computer data is in what is called binary format. This means that it is always a 0 or a 1. It only has these two states and must be in one of them.
There are several fundamental data units which include:
Bit - A data unit which must be in one of the two binary states described above. It is the smallest data unit that exists.
Byte - 8 bits of data which has a possible value from 0 to 255.
Word - Two bytes or 16 bits of data with a possible unsigned value from 0 to 16535.
Computer Hardware
The term computer hardware refers to the various electronic components that are required for you to use a computer along with the hardware components inside the computer case. As you know your computer equipment is made of several common components. These include:
The main computer box.
A monitor - Looks like a television screen.
A keyboard.
A mouse.
Speakers.
An optional printer
The Main Computer Box
The main computer box is made of several computer hardware components and subcomponents which include:
The motherboard - Hold the following computer hardware subcomponents:
Memory -Used to provide temporary storage of information as discussed earlier.
Microprocessor - Used to provide the processing of data function as discussed earlier.
Video interface card which is also called the video card - This card is an interface between the computer monitor and the motherboard and its subcomponents such as the microprocessor and memory.
Sound card - is an interface between the computer speakers and the motherboard and its subcomponents such as the microprocessor and memory.
The Case
The drawing below shows a typical case.
Computer Software
The term software describes the programs that run on your system. This includes your computer operating system and other computer programs which run.
Software is written in a computer language (such as Basic, C, Java, or others) by programmers.
The computer language is in a text format and can be read by a person although if you do not understand the structure and rules of the language you may not understand it very well.
Once a program is written, an operation is performed on it which is called compiling.
What is a Network?
Most people who work on a corporate or organizational network think about the network in component parts. The three main parts are:
