About Me.





Hi, I am Fakru Ahmed Bashu and I write How to use your computer Blog to help those who are not comfortable in using their computers. I started this blog in 2010. 



                                                           "life is an eternal quest about knowing oneself. it's time to challenge yourself, to rediscover your hidden traits, talents, and tendencies. several 
inconvenient questions, which you have swept under the carpet, might resurface. here is a collection of "about me" quotes. each noted author has revealed her or his unique qualities. when you read these "about me" quotes, you will find the inspiration to ask yourself "is that true about me?" i do my thing and you do yours. i am not in this world to live up to your expectations, and you are not in this world to live up to mine. you are you and i am i, and if by chance we find each other, then it is beautiful. if not, it can't be helped. i am enough of an artist to draw freely upon my imagination.” i like to be a free spirit. some don't like that, but that's the way i am. i am only a public entertainer who understands his time.i am you; you are me. you are the waves; i am the ocean. know this and be free, be divine. the deep root of failure in our lives is to think, 'oh how useless and powerless i am.' it is essential to think strongly and forcefully, 'i can do it,' without boasting or fretting. i am not myself in any degree ashamed of having changed my opinions.i am one of the people who love the why of things.when i let go of what i am, i become what i might be.i am not only a pacifist but a militant pacifist. i am willing to fight for peace. nothing will end war unless the people themselves refuse to go to war.”i am so clever that sometimes i don't understand a single word of what i am saying.i am extraordinarily patient, provided i get my own way in the end.without knowing what i am and why i am here, life is impossible.i am neither especially clever nor especially gifted. i am only very, very curious."

The Five Generations of Computers.

“Necessity is the Mother of Invention”


Computer: Machine capable of executing instructions to perform operations on data. The distinguishing feature of a computer is its ability to store its own instructions. This ability makes it possible for a computer to perform many operations without the need for a person to enter new instructions each time. Modern computers are made of high-speed electronic components that enable the computer to perform thousands of operations each second.


The history of computer development is often referred to in reference to the different generations of computing devices. Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, and more powerful and more efficient and reliable devices. Read about each generation and the developments that led to the current devices that we use today.



  • First Generation – 1940-1956: Vacuum Tubes




  • Second Genera tion – 1956-1963: Transistors




  • Third Generation – 1964-1971: Integrated Circuits




  • Fourth Generation – 1971-Present: Microprocessors




  • Fifth Generation – Present and Beyond: Artificial Intelligent




  • 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. First generation computers relied on machine language to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts


The UNIVAC and ENIAC computers are examples of first-generation computing devices.


The UNIVAC was the first commercial computer delivered to a business client, the U.S.


Census Bureau in 1951.



  • Second Genera tion – 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 50s. 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. Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output.


Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN. These were also the first computers that stored their instructions in their memory, which moved from a magnetic drum to magnetic core technology. The first computers of this generation were developed for the atomic energy industry.



  • 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.


Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory. Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors.



  • 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. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer – from the central processing unit and memory to input/output controls – on a single chip.


In 1981 IBM introduced its first computer for the home user, and in 1984 Apple introduced the Macintosh. Microprocessors also moved out of the realm of desktop computers and into many areas of life as more and more everyday products began to use microprocessors.


As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet. Fourth generation computers also saw the development of GUIs, the mouse and handheld devices.



  • 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. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization.


DID YOU KNOW…!!!
An integrated circuit (IC) is a small electronic device made out of a semiconductor material. The first integrated circuit was developed in the 1950s by Jack Kilby of Texas Instruments and Robert Noyce of Fairchild Semiconductor.

How to fasten your Computer. (Part – 1)

“In this section I will be teaching you how to speed up your computer. (Part – 1)”  

  • When you fing your Computer is booting slow.
When you find that your computer is slow after the boot (After you log In).

Great question, and one that I can understand as my PCs also seem to gradually get slower and slower on boot as this, that and the other applications have to check in and get updated definitions, applications, data files…!!! Shorten the time it takes for your desktop to appear when you turn on your PC No matter how fast your PC boots, it’s not fast enough. Here are several options to get you right to your desktop as quickly as possible after startup.

Perform a Boot Defragment:

PULL YOUR BIOS:

When your computer has slow boot, it may have nothing to do with operating system (O/S). There is a Basic Input/Output System known as the BIOS. The BIOS runs at the startup sequence where it configures devices and then boots the operating system. However, if the configuration is messy and has some unclear commands, this will cause a slow boot up. Depending on your mother board manufacturer, you may have the access the BIOS differently.

  1. Turn on your computer, and hold down delete or F2 (Function key).
  2. In the BIOS window, look for the Boot Menu option.
  3. Choose the QUICK BOOT to turn off memory test.
  4. Make sure the hard drive comes first in the BOOT ORDER.
  5. Turn off any logo displays.
  6. Save and Restart your computer.
Follow the picture given bellow.

This is an example of BIOS that will cause a very slow boot up. Follow the advice above to restructure your BIOS to load your configuration a quick as possible.

Disable ON BOARD sound and GRAPHICS

Only do this if you have a third party sound and graphic card already installed.









  1. In the BIOS menu, select Onboard Device or Integrated peripherals.
  2. Disable the onboard chips and turn off unused network adapters.
  3. Save and Restart your Computer.
After you log in to your computer

  • BOOT MENU Default Settings
If you are using XP or Vista you can access the boot menu by loading your MSCONFIG. During the boot up your computer issues a time out to find new hardware and software is shown. You can short this time to boost your startup speed.

  1. Open your Start menu.
  2. Click on Run.
  3. In the command screen type msconfig.
  4. In the system configuration utility, click either BOOT tab.
  5. In the boot menu, change the default setting for Time Out from 30 to 5 seconds.
Follow the picture given bellow.

Remove Boot Up Passwords.

Having a password lock computer can add to your slow boot up. The operating system must completely halt the boot up to allow you to type in your text based password. Eliminating this boot password option will give you a welcome speed boost.

  1. Click on the Start.
  2. Click on Settings.
  3. Click on Control Panel.
  4. Click on user accounts.
  5. Uncheck User must enter user name passwords.
  6. Click Apply and OK.
Follow the picture given bellow.

This will even speed up your computer after logging in to the system.

Use disk clean up option:

Disk Cleanup–This tool allows you to clean up compressed and unnecessary files collected during Windows operations. Windows has judged these files safe to be deleted. This file can be anything from your temporary internet files to programs no longer in use.

HOW TO Cleanup your Disk:

  1. Click on Start.
  2. Click on Programs.
  3. Click on Accessories.
  4. Click on System Tools.
  5. Click Disk Cleanup.
Follow the picture given bellow.

Under the More Options tab, you can clear data under three categories. This is highly recommended if you want to free up more space for performance speed. With just a few clicks you can learn how to clean up a slow computer in multiple areas.
