You cannot have any application without it. Imagine that when you turn on your computer, browse internet, write document, play a game, listen to music, or even just clicking icons; those applications were made with enormous numbers of programming codes.

A programming language is a set of keywords (commands) and grammar rules (syntax) designed for creating instructions that a computer can ultimately process or carry out.

Programming languages are categorized based on the levels, generations, and paradigm.

By levels, programming languages are categorized into two, low-level language and high-level language. Low-level language typically includes commands that specially made for particular microprocessor family (e.g.: Intel, AMD, PowerPC) and it is designated to make instructions for the lowest level of the computer’s hardware, such as the processor, registers, and RAM locations. Machine languages and assembly languages are low-level. They constitute of binary digits (1s and 0s). Differently, high-level language uses commands words and grammar based on human languages that will be translated to assembly/machine language. Java, C, BASIC are examples of high-level. The commands are using human words such as PRINT, WRITE, etc.

By generation, along with the computer (see the previous article), the programming language develops through generations. The first generation is what we call machine language. The second generation is assembly language. Programmers can use abbreviated command words, called operation codes, such as ADD but still for specific machine. The third generation languages used easy command words, such as PRINT and OUTPUT. Here, the examples are COBOL (Common Business Oriented Language), Fortran (Formula Translator), Pascal, and BASIC. In 1969, scientists develop the fourth-generation languages, which more closely resemble human languages, such as SQL (Structured Query Language) and RPG (Report Program Generator). SQL are used in database applications. In 1982, a group of Japanese researchers began work on Prolog (Programming in Logic) which is a declarative language and called by some experts the fifth-generation language. Some disagree with this classification and instead define fifth-generation languages as those that allow programmers to use graphical or visual tools to construct program.

Programming paradigm is a way of conceptualizing and structuring the tasks a computer performs. By this paradigm, programming languages are divided into “procedural”, “Object-oriented”, “declarative”, “functional”, and “Event-driven”.

Well I want to say sorry for this. The topic that I want to bring is the history of the computer generation.

When we see the meaning of computer in Wikipedia, a computer is a programmable machine that receives input, stores and manipulates data//information, and provides output in a useful format.

Actually we have to see etymologically that the word Computer comes from compute added with suffix -er that will mean someone/something that do computations (counting). And that is the essence of the prototypes and the first generation of Computer; machine to do computations (basic counting numbers, i.e addition, subtraction, multiplication, division). But through years, computers faced a lot of revolutionary improvements. The computer’s definition itself moved from just a computation device (or even a person who do calculations) to a complex machine that can do a lot of things (it able us to view images, surf the Internet, watch videos, listen to music, type documents, etc.).

The First Generation of Computer

ENIAC

This generation has a big theme of Vacuum tubes. A lot of vacuum tubes were used in the prototype and first generation of computer. The vacuum tubes are used for circuitry. This type of computer drains a lot of electricity and space. It is also produce great amount of heat. Programming of this computer used the machine language (the lowest programming language level) that is understandable by the machine. The input used paper tape and punch cards and the output used the printout. We rarely will see this type of computer. The example of these computers are UNIVAC and ENIAC. UNIVAC is the first commercial computer that was used by US Bureau Census in 1951.

Transistors: The Base of The Second Generation

While the first generation used the ineffective vacuum tubes, the second generation was brought because of the founding of transistors. Invented in 1947 and used in computer in late 1950s, transistors made the computers smaller, cheaper, faster, and lowering its power need and the heat it produces.

IBM 7094

One transistor is equivalent with 40 vacuum tubes. These computers used assembly language (programming language that symbolize the instructions in short words like ADD, LOAD, etc.) and early versions of COBOL and FORTRAN (early high programming language). The second generation is the first to save the instructions in memory. The I/O (Input-Output) system still same with the first. One of the example of this computer is IBM 7094.

Third Generation with Integrated Circuits

Transistors had made a breakthrough in the computer’s history. But, another breakthrough was made by integrated circuits. These circuits can contain thousands and more transistors in a single chip. The integrated circuits are called semiconductor chips or silicon chips.

DEC PDP-8

This type of chip made the computers become faster, more powerful, cheaper, and smaller. This generation too introduced the using of keyboard, monitor, and operating system. Two of them are IBM S/360 and DEC PDP-8

IBM S/360

Microprocessor leads to the Fourth Generation

Putting millions of transistors and thousands of integrated circuits in a single chip will make the computer becomes really powerful. That is the core of this fourth generation. With this innovation, chip companies like Intel, AMD, etc. develop themselves rapidly and demanded by the market. This microprocessor we call it as the central processing unit because it can perform millions to billions operations per second. One of the starters of this fourth generation is “the personal computer” Altair 8800, Apple II, etc. Nowadays all computer produced now are more advanced than those and the processor technology is more advanced. This generation improves GUI (graphical user interface), mouse, hand held devices, and other peripherals.

Artificial Intelligence, the Now Developing and Future Computers

The fifth generation of computer is the computer capable of having artificial intelligence. One of the applications is voice recognition. Using parallel processing, superconductors, nanotechnology, and quantum computing, this type wants to change the face and system of the computer. The goal is the computer will understand natural language as the input and capable of learning and self-organization.

Anyway, I would like to announce that there will be some special article about some good freewares or open source software and about some IT stuffs and lingo…

Hope all of you enjoy…

These editions are ready stock and Microsoft allow upgrade to Windows 7 from Vista. What are the differences between those 3 editions? In this article I will give some comparisons:

These editions are compatible to use with 32-bit and 64-bit machines (processors).

What is the difference between 7 and Vista?

1. Seven improved the using of taskbar and full screen previews.

You can pin any program to the taskbar, rearrange the icons on the taskbar just by clicking and dragging. With Windows 7, it’s easier to do things you do all of the time. For example, before, when you wanted to compare two open windows, you had to manually resize your open windows to show them side by side. With Snaps, you can simply grab a window and pull it to either side edge of the screen to fill half the screen. Snap windows to both sides, and it’s easier than ever to compare those windows.

2. Better device management.

A new technology in Windows 7 called Device Stage takes device management a step further. Device Stage helps you interact with any compatible device connected to your computer. From Device Stage you can see device status and run common tasks from a single window.

3. HomeGroup.

HomeGroup, a new feature in Windows 7, makes connecting the computers easier. HomeGroup is set up automatically when you add the first PC running Windows 7 to your home network. Just add more PCs with Windows 7 to the HomeGroup to share from each PC with all the PCs. Then, sharing files across the various PCs in your home—and many other devices—is as easy as if all your data were on a single hard drive. So you can store digital photos on a computer in your den and easily access them from a laptop anywhere in your home. Similarly, once in a HomeGroup, the printer in your den is shared automatically with all of the PCs in your home.

4. Faster, more responsive

To improve performance, Windows 7 is designed to make PCs start up, shut down, resume from standby, and respond faster. Some people have reviewed Windows 7, and they concluded that 7 is faster than Vista when starts up and shut down.

5. Compatibility

You can expect that most of the products that work with Windows Vista to work with Windows 7. In addition, with Windows 7 Professional or Ultimate, you’ll be able to run many productivity and business programs designed for Windows XP. Some additional software will be necessary and it will be available free-of-charge as a download from Microsoft.

FYI, upgrade from Vista to 7 is available on 22nd. To see more information about 7 you can access Microsoft website. So, what’s your decision? Ready for 7??

(This post is a summary from Microsoft’s official site)

Beside his incredible speed, USB 3.0 an use Dual-simplex protocol with four extension cables that separate the signaling from USB 2.0 so it can reach its total speed (5.0 Gbit/s), it also already support full duplex data transfer and power management facility so it can be set in idle, sleep and suspend state.
Although its speed and new features is incredible, USB 3.0 has still some weaknesses. There is still no Host Controller for USB 3.0 port that integrated in motherboard, so you must add PCI-Express add-on card as the Host Controller. USB 3.0 has different connectors than USB 2.0. The Backward Compatibility feature in USB 3.0 just used in USB 3.0 connectors, and it is used to read the USB 2.0. In that case, USB 3.0 cannot be used in USB 2.0 connectors.

There is a chance the USB 3.0 Host Controller will be available around this year in a form of PCI-Express add on card. But for the integrated port in the motherboard, probably it will be available next year.

With USB 3.0 around, probably it is time for computer users to migrate to this new generation of USB.
