Hi everyone, I had been busy the past couple of days and did not have the time to write articles. However, with the weekend approaching, I will be taking this opportunity to write a good many articles. Something over the past few days inspired me to write about computers.
Now computers are a passion of mine and I thought it would be a good idea to write about them. Also, being in the I.T. industry for a great many years, I feel obliged to write to my best extent on computers.
Now, I am beginning a series of articles here similar to the financial series of articles that I would be posting up soon.
Now, let us define computers: A computer is the most basic understanding is an electronic device that processes data, converting it into information that is useful to people.
Even at this very moment, you are using a computer to read this article, and the history of computers dates way back to the 17th century in what was known as Generation zero. If you are wondering, we are currently in the fifth generation with artificial intelligence, quantum computation, nanotechnology, etc;
Now, I will write on the history of computing which would be interesting to some people, and fascinating to others in another article.
In this article, I am going to talk more about the different computers that are present in the current world:
· Desktop computers
· Workstations
· Notebook computers
· Tablet computers
· Handheld computers
· Smart phones
· Supercomputers
· Mainframe computers
· Minicomputers
Desktop computers
Different type of computers
The most common computer used in today’s world are the desktop computers which were specially built for personal use be it at home or work. These computers are everywhere, from your office, to your house, schools, laboratories and even public places like a public library, universities and so on. There is a great chance that you have accessed this website using a desktop computer.
Today’s computers are brilliant at task management than many years ago. Today’s desktop computers can be used to communicate, produce music, edit photographs and videos, play sophisticated games, and much more.
As the name implies, a desktop computer is a full size computer that is too big to be carried around. Nowadays, most desktop computers are equipped with two primary hardware solutions – the monitor and a casing inside which is stored the central processing unit (CPU), the motherboard, the graphic card, storage devices, buses, power supply and so on.
A desktop computer is also equipped with a keyboard and mouse which are connected to their appropriate ports at the back of the casing.
Workstations
A workstation is a specialized, single user computer that typically has more power and features than a standard desktop computer. These machines are more popular in the lab of scientists, engineers or even animators who require a system with greater than average speed and power to perform sophisticated calculations, rendering, or high level tasks.
Workstations often have larger and higher resolution monitors, and accelerated graphics. In relation to this, I would give you an example : - such as the Quadro series of graphic cards. They are commonly used in workstations.
This higher specifications allow for advanced architectural engineering design, modeling ,animation and even video editing.
Notebook computers
Notebook computers as the name implies is approximately the size of an 8.5-11 inch notebook and can easily fit inside a briefcase. Since most people including yourself would set this device on your lap and use it conveniently in eateries, cafes, at the work place, in education institutions and so on, hence the name laptop.
Notebook computers can operate on alternating current or special batteries. These special device also weighs less than 8 pounds and some even lesser than three pounds.
Using a laptop is as simple as opening a book. Think of it as opening your notebook. Similarly, when a laptop is opened, the upper lid will present a screen or lcd monitor. At the bottom is the keyboard and beneath the keyboard is the specialty hardware such as the motherboard, cpu, hard-disk and so on.
The portability of laptops is one of the most major reasons for the increased use of laptops nowadays. They are the mobile computers that can be carried anywhere and used conveniently.
Tablet PC
Different type of computers
Tablet PC’s are some of the more newer developments in portable, full featured computers. Tablet PC’s just like a notebook offers the full range of functionalities except that they are lighter and accepts input from pen/pointers known as a stylus.
Most interactions are done directly via the screen of the computer and some tablet PC’s also allow for input via the user’s voice. As you know, even phones these days accept voice commands to get things done.
Tablet PC’s can run specialized versions of standard programs and can be connected to a network or to the internet. Certain and in most new models now – a keyboard and a mouse can be attached as well.
Tablet PC’s are used mainly in the graphic design field where drawing on the tablet PC’s can be translated into digital drawings and be edited by various graphic editing tools.
Handheld PC’s
Different type of computers
Handheld personal computers are computing devices small enough to fit in your hand. A popular type of handheld computer is the personal digital assistant (PDA).
A PDA is no larger than a small appointment book and is normally used for special applications such as taking notes, displaying telephone numbers and addresses and keeping track of dates or agendas.
Many PDA’s can be connected to computers to exchange data. Most PDAs come with a pen (stylus) that allows for handwriting recognition and some even have tiny built-in keyboards or microphones for voice input.
A wireless connection (Wi-Fi) can be used to access the internet with a PDA. PDAs in the later part of this century were converted into phones, cameras, music players and GPS.
The demands for PDA phones have been in the increase and of late have been mostly replaced by smart-phones that are equipped with much functionality similar to a computer.
Smart phones
Different type of computers
Smart phones are handheld devices or mobile phones that have a processing unit attached to act as a handheld computer cum phone.
These phones offer advanced features not typically found in normal cellular phones. These phones come with additional features beyond the traditional SMS and calling features. Smart phones these days allow you to surf the internet using your phone, take pictures, videos, listen to music, conduct presentations, record voice, play games, e-mail, and many other additional features.
Smart phones are also equipped with an operating system just like your desktop or laptop computers are equipped with an operating system, Windows, Linux, etc;
Supercomputers
Different type of computers
Supercomputers are the most fastest, and expensive modern computer systems. They are mostly used for intense processing and forecasting such as forecasting the weather, or super high resolution graphics such as ray traced images.
Government processes such as immigration clearances, and all other high level functionalities are handled by a supercomputer.
Supercomputers are also extensively used in the military to manage and calculate or even analyze full range of information from coordinates to traffic control and even launching systems.
Today, the world’s fastest supercomputer was developed by IBM – the IBM Roadrunner which runs on 1.026 – 1.105 Pflops or petaflops and is placed in the Los Alamos National Laboratory, New Mexico USA taking up a space of 6000 square feet.
Mainframe computers
Different type of computers
Mainframe computers are used in large organizations such as insurance companies and banks, where many people frequently need to use the same data. In a traditional mainframe environment, each user accesses the mainframe’s resources through a terminal (network terminal).
There are two kinds of terminal, one is a dumb terminal which does not process or store data, just basic I/O – input output and the intelligent terminal which can perform processing operations but these terminals normally do not have any storage.
Mainframes are large and powerful systems to handle the processing of thousands of users at any one time. Most large organizations implement mainframes due to their flexibilities in which department computers can be allocated a certain functionality that is related to the department in response to all programs.
For instance, an airline company which wishes to sell tickets online through the internet will require to connect their current website interface to a mainframe system.
You as the user would then connect to the website or the mainframe system to key in your ticket purchase.
Minicomputers
Different type of computers
Minicomputers are small sized computers which have their capabilities between the range of a personal desktop computer and a mainframe.
Minicomputers were replaced by the microcomputers which took over the reign of those mighty minicomputers due to their greater processing power.
Today, mini and micro computers are replaced by much more powerful systems as you can see from above.
Well, that’s some bit on the various types of computers. The next time perhaps I will write an article on the history of computers from Generation 0 – Generation 5 (currently).

The 3 idiots summary
THE 3 IDIOTS
Farhan Qureshi (R. Madhavan), Raju Rastogi (Sharman Joshi), and Rancchoddas "Rancho" Shyamaldas Chanchad (Aamir Khan) are three engineering students who share a room in a hostel at the Imperial College of Engineering, one of the best colleges in India. While Farhan and Raju are average students from modest backgrounds, Rancho is from a rich family. Farhan wants to become a wildlife photographer, but has joined engineering college to fulfil his father's wish. Raju on the other hand wants to uplift his family fortunes. Rancho is a wealthy genius who studies for the sheer joy of it. However, Rancho's passion is for knowledge and taking apart and building machines rather than the conventional obsession of the other students with exam ranks. With his different approach Rancho incurs the wrath of dean of college, Professor Viru Sahastrabudhhe (ViruS) (Boman Irani). Rancho irritates his lecturers by giving creative and unorthodox answers, and confronts ViruS after fellow student Joy Lobo hangs himself in his dormitory room. Joy had requested an extension on his major project on compassionate groundshis father had suffered a strokebut ViruS refused, saying that he himself was completely unmoved by his own son's accidental death after being hit by a train. Rancho denounces the rat race, dog-eat-dog, mindless rote learning mentality of the institution, blaming it for Lobo's death.
Threatened by Rancho's talent and free spirit, ViruS labels him an "idiot" and attempts on a number of occasions to destroy his friendship with Farhan and Raju, warning them and their parents to steer clear of Rancho. In contrast, ViruS model student is Chatur Ramalingam or "Silencer", (Omi Vaidya) who sees a high rank at the prestigious college as his ticket to higher social status, corporate power, and therefore wealth. Chatur conforms to the expectations of the system. Rancho humiliates Chatur, who is awarded the honour of making a speech at an award ceremony, by substituting obscenities into the text, which has been written by the librarian. As expected, Chatur mindlessly memorises the speech, without noticing that anything is amiss, partly aided by his lack of knowledge on Hindi. His speech becomes the laughing stock of the audience, infuriating the authorities in the process.
Meanwhile, Rancho also falls in love with ViruS' medical student daughter Pia (Kareena Kapoor) when he, Raju and Farhan crash her sister's wedding banquet in order to get a free meal, in the process further infuriating ViruS.
Meanwhile, the three students continue to anger ViruS, although Rancho continues to come first in every exam, while Chatur is always second, and Farhan and Raju are inevitably in the last two positions. The tensions come to a head when the three friends, who are already drunk, break into ViruS's house at night to allow Rancho to propose to Pia, and then urinate on a door inside the compound before running away when ViruS senses intruders. The next day, ViruS threatens to expel Raju lest he talks on the other two. Unable to choose between betraying his friend or letting down his family, Raju jumps out of the 3rd floor window and lands on a courtyard, but after extensive care from Pia and his roommates, awakes from a coma.
The experience has changed Farhan and Raju, and they adopt Rancho's outlook. Farhan decides to pursue his love of photography, while Raju takes an unexpected approach for an interview for a corporate job. He attends in plaster and a wheelchair and gives a series of non-conformal and frank answers. However, ViruS is unsympathetic and vows to make the final exam as hard as possible so that Raju is unable to graduate. Pia hears him and angrily confronts him, and when ViruS gives the same ruthless reply he gives to his students, she denounces him in the same way that Rancho did over the suicide of Lobo. Pia reveals that Viru's son and her brother was not killed in an accident but committed suicide in front of a train and left a letter because ViruS had forced him to pursue a career in engineering over his love for literature; ViruS always mentioned that he unsympathetically failed his son on the ICE entrance exams over and over to every new intake of ICE students. After this, Pia walks out on the family home, and takes ViruS's spare keys with her. She tells Rancho of the exam, and he and Farhan break into ViruS's office and steals the exam and give it to Raju, who with his new-found attitude, is unconcerned with the prospect of failing, and refuses to cheat and throws the paper away. However, ViruS catches the trio and expels them on the spot. However, they earn a reprieve when Viru's pregnant elder daughter Mona (Mona Singh) goes into labour at the same time. A heavy storm cuts all power and traffic, and Pia is still in self-imposed exile, so she instructs Rancho to deliver the baby in the college common room via VOIP, after Rancho restores power using car batteries and a power inverter that Rancho had dreamed up and ViruS had mocked. Rancho then delivers the baby with the help of a cobbled-together Vacuum extractor.
After the baby is apparently stillborn, Rancho resuscitates it. ViruS reconciles with Rancho and his friends and allows them to take their final exams and they graduate. Rancho comes first and is awarded ViruS's pen, which the professor had been keeping for decades before finding a brilliant enough student to gift it to.
Their story is framed as intermittent flashbacks from the present day, ten years after Chatur vowed revenge on Rancho for embarrassing him at the speech night and promised to become more successful than Rancho a decade later. Having lost contact with Rancho, who disappeared during the graduation party and went into seclusion, Raju and Farhan begin a journey to find him. They are joined by Chatur, now a wealthy and successful businessman, who joins them, brazenly confident that he has surpassed Rancho. Chatur is also looking to seal a deal with a famous scientist and prospective business associate named Phunsukh Wangdu. Chatur sees Wangdu, who has hundreds of patents, as his ticket to further social prestige. When they find Rancho's house, they walk into his father's funeral, and find a completely different Rancho Jaaved Jaffrey. After accusing the new man of stealing their friend's identity and profiting from his intellect, the host pulls a gun on them, but Farhan and Raju turn the tables by seizing the father's ashes and threatening to flush them down the toilet. The householder capitulates and says that their friend was a destitute servant boy who loved learning, while he, the real Rancho, was a lazy wealthy child who disliked study, so the family agreed to let the servant boy study in Rancho's place instead of labouring. In return, the real Rancho would pocket the qualifications and the benefits thereof, while the impersonator would sever all contact with the world and start a new life. The real Rancho reveals that his impersonator is now a schoolteacher in Ladakh.
Raju and Farhan then find Pia, and take her from her wedding day to Suhas by performing the same tricks with his material possessions, and having Raju turn up to the ceremony disguised as the groom and eloping with Pia in public. When they arrive in Ladakh, they see a group of enthusiastic Ladakhi children who are motivated by love of knowledge. Pia and the fake Rancho rekindle their love, while Chatur mocks and abuses Rancho the schoolteacher before walking away. When his friends ask what his real name is, he reveals that it Phunsukh Wangdu and phones Chatur, who has turned his back, to turn around and meet his prospective business partner. Chatur is horrified and falls to his knees, accepts his defeat and continues to plead his case with Phunsukh to establish the business relationship he was after.
