What is a software?

A software refers to any program that tells the computer system what to do. 

For some information:

Computer software, or simply software, also known as computer programs, is the non-tangible component of computers. Computer software contrasts with computer hardware, which is the physical component of computers. Computer hardware and software require each other and neither can be realistically used without the other.

Software is one of the topics we learned in CS 1

DIGITIZATION

Another topic was discussed by Sir Tom Secundo, one afternoon. Digitization is the process of taking a visual image, audio recording, etc and converting it to a binary form for the computer.

Digitizing or digitizations the representation of an object, image, sound, document or a signal (usually an analog signal) by a discrete set of its points or samples. The result is called digital representation or, more specifically, a digital image, for the object, anddigital form, for the signal. Strictly speaking, digitizing means simply capturing an analog signal in digital form. For a document the term means to trace the document image or capture the "corners" where the lines end or change direction.

ASSEMBLE IT ON YOUR OWN!

With enough knowledge about computers and its parts, everyone can assemble a computer.

Because, while doing you are learning, I, myself with the help of my group mates, we assembled the mother board and other parts.


TRY!

Grow old with you...

So let me assemble our computer

Put you to seat when you've had too much to type
I could be the comp. who grows old with you 

I wanna grow old with you...

(with the tune of 'Grow old with you' by Adam Sandler)

"I want to grow old with you! Speak to me, my computer! Yes, I want to grow old with you!", the Computer Addict said.

Not only people, animals and plants are getting older. Even computers grow old also like us. Computer, is getting old as time passes. As the time passes, the better the computer. 

Your computer now is in it's fifth generation, meaning to say, there are 5 generations of computer. 

Generations of Computers

first generation

First Generation (1940-1956) Vacuum Tubes

The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.

Second Generation (1956-1963) Transistors

Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors.

Third Generation (1964-1971) Integrated Circuits

The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.

Fourth Generation (1971-Present) Microprocessors

The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip.

Fifth Generation (Present and Beyond) Artificial Intelligence

Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality.

Machine Cycle

This is the machine cycle

The next topic is about the Machine Cycle.
 The machine cycle is a 4 process cycle that includes reading and interpreting the machine language, executing the code and then storing that code.

4 steps:

1. Fetch - Retrieve an instruction from the memory.
2. Decode - Translate the retrieved instruction into a series of computer commands.
3. Execute - Execute the computer commands.
4. Store - Sand and write the results back in memory

OS?

OS? yes, OS. OS is our next topic in Computer Science 1. How to download it, etc.

An operating system (OS) is a collection of software that manages computer hardware resources and provides common services forcomputer programs. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function.

DON'T WORRY

"Do not worry. I have notes.
You can read it. And I hope it can help you."

These lines were buried beneath the heart of the scholars. Especially when a Long Test is approaching.

Very hard! It is so easy. I don't care. Effortless. Nosebleed. I'm dying. I like it.
Those lines were painted in the eyes of a scholar.

P.S. If you study your lessons, you'll have high score. :)
