DIGITAL LOGIC SIMULATOR

Multimedia Logic - Tutorial 1 - Simple Circuits

Tutorial 2 - AND / OR Gates

These are some videos that show or teach you on how to use the software

 of multimedia logic.

But!!!!

You should download and install the software of multimedia logic.

These are some links to get the software..

http://sourceforge.net/projects/multimedialogic/

or

you can get the software from this video and it also show you how and 

where to download the software....

Input and Output Devices

INPUT DEVICES :-                     

Keyboard || Mouse || Scanner || CD-Rom || Game Controller

OUTPUT DEVICES :-

Monitor || Printer || Disk Drive || Floppy Drive || CDRW-Rom || Speaker

This is an examples of input and output devices...

Input and output is the communication between an information processing system and the outside world.

Input :- the signal or data received by the system

Output :- the signal or data sent by the system

In computer architecture, the combination of the CPU and main memory is considered the brain of a computer.

Input and output devices can be characterized by 

1. Behavior :- input, output, storage
2. Partner :- human or machine
3. Data rate :- bytes/sec, transfer/sec

Input and output System Design :-

What is input design and output design in system design ?????

            Input design is input facilities the entry of data into the computer system. Input design involves the selection of the best strategy for getting data into the computer system at the right time as accurately as possible. This is because the most difficult aspect of input design in accuracy. The use of well-defined document can encourage users to record data accurately without omission. 

             For example, if the the customer's telephone number is needed input data, the sales order form should have a specific line that is clearly labeled "customer telephone number". Having several lines labeled "customer information" would be less effective. 

             This is because sometimes only the name and address would be filled in leaving out the telephone number. Input design must capture all the data that the system needs, without introducing any errors. Input errors can be greatly reduced when inputting directly by using appropriate forms for data capture and well designed computer screen layout.  

Example of typical transformation process...

Server Computers :-

• Applications are increasingly run on servers
• web search
• office applications
• virtual worlds
• Requires large data center servers
• multiple processors
• networks connections
• massive storage
• space and power constraints
• Server equipment built for 19" racks
• multiples of 1.75" (1U) high

 

This two figures shows that the flow of the server computers...

DIGITAL LOGIC

This is the basic logic gates that you must know before learn others..

You also need to remember that we need the value of 0 and 1 only...

This is some example of truth table...

These are the samples of logic circuit..

An example of Sum-of-products (SOP) and Product-of-sums (POS)..

We have 2 ways to simplify the Boolean equation :-

1)  By using Karnaugh Map 

First video...

Second video...

Third video..

Fourth video..

2)    By using Laws of Boolean Algebra...

This is the Basic Laws of Boolean Algebra..

These all the videos on how to convert information from circuit to truth table to Karnaugh Map. And last, simplified it to Boolean expressions..

Good luck guys..

I really hope you can understand this video.. Take your time and listen these video..
