The first laptop computers! "Click" the images to see more information.
Laptop and pocket computers have been around for decades, but bear little resemblance to today's powerful systems.

What defines a laptop computer? Most people agree on light-weight, battery operation, with the keyboard and display device in a self-contained package. A full-size keyboard may or may not be a requirement, depending on your view-point.

Even the earliest systems were true computers, with tiny keyboards and tiny screens. They required no operating system to control their simple hardware - they were usually programmable in the popular BASIC programming language, or had their own proprietary operating system.

Macintosh - 1984 By Apple Computer






The Macintosh computer was released in January of 1984, with 128K RAM of memory. It quickly became obvious that this was insufficient, so eight months later Apple released an updated version, un-officially referred to as the 'Fat Mac'. It has 512K RAM, four times as much.

Before the Macintosh, all computers were 'text-based' - you operated them by typing words onto the keyboard. The Macintosh is run by activating pictures (icons) on the screen with a small hand-operated device called a "mouse". Most modern-day computers now operate on this principle, including modern Apple computers and most others which run the Microsoft Windows operating system.

Except for the very expensive and unpopular Apple Lisa which came out in 1983, the Macintosh is considered to be the first commercially successful computer to use a GUI (Graphical User Interface), as seen below.




The Macintosh has no room for internal expansion options - no other cards or devices can be installed, nor can the graphics capabilities be upgraded. Actually, it takes special tools just to get the case open.

Although adequate for desktop publishing, many found the 9" (diagonal) black & white screen rather small and limiting. The uniqueness of its GUI operating system probably saved the Macintosh from obscurity like so many others.

Like the Commodore Amiga 1000 and the Macintosh Portable, the Macintosh has the signatures of the designer's cast into the inside of the case.

Don't forget to use your official Macintosh carrying bag when transporting your favorite computer to remote locations!

    MATHS TRICKS: CUBE ROOT

    Cube Root of a given perfect given in any exam can be found out quickly, easily and effortlessly. This article shows you how. Before going to the method you should keep in mind the following…
    While preparing for exam, write down cubes of 1 to 10 and learn it by heart.
    1 x1x1 =1
    2x2x2=8
    3x3x3=27
    4x4x4=64
    5x5x5=125
    6x6x6=216
    7x7x7=343
    8x8x8=512
    9x9x9=729
    10x10x10=1000
    Now if you observe the above cubes closely, you will find that the unit places of any perfect cube can be only any of these….
    1 or 8 or 7 or 4 or 5 or 6 or 3 or 2 or 9 or 0
    This information is very important.
    How will it help you? Let us learn through an example..
    Suppose you got a number = 12167
    You have to find the cube root of 12167.
    Now you should quickly make out that since unit place of 12167 = 7, the unit place of the cube root of 12167 should be = 3 .
    If the given number is 328509 then you should immediately tell to yourself that since unit place of 328509 is 9, the unit place of cube root of 328509 should be = 9
    RULE 1
    In the same way learn the following by heart .. On the left side is the unit digit of perfect cube and on the right side unit digit of cube root
    If cube has unit digit as 1 = cube root has unit digit as 1
    8 = 2
    7 = 3
    4 = 4
    5 = 5
    6 = 6
    3 = 7
    2 = 8
    9 = 9
    RULE 2
    If the given perfect cube has 4 or 5 or 6 digits then the cube root will have = 2 digits
    Eg: cube root of 12167 = 23,
    cube root of 704969= 89
    If the given perfect cube has 7 or 8 or 9 digits then cube root will have = 3 digits
    IMPORTANT TIP: Try to group the numbers in a set of 3 digits from Right to left and the number of such groups you get is the number of digits in your cube root
    Eg: 12167 can be grouped as 12 and167 ( RIGHT TO LEFT …SET OF THREE DIGITS)
    Therefore the number of digits in cube root should be 2 as there are only two such groups….
    Eg 704969 can be grouped as 704 and 969
    Therfore the number of digits in cube root should be 2
    LET US LEARN NOW HOW TO FIND OUT CUBE ROOTS OF A GIVEN PERFECT  CUBE QUICKLY
    Q)  The cube root of 21952 is ?
    a) 18 b) 19 c) 28 d) 148
    Ans) Let us learn the trick step by step
    STEP 1 : The cube has unit digit =2 ,   therefore the cube root should have unit digit = 8
    So you can eliminate the option b
    STEP 2: The number 21952 can be grouped as 21 and 952  (Right to left in batches of three digits)
    So your cube root should have two digits. Now you can eliminated option d
    STEP 3: VERY IMPORTANT………….
    21952 =
    We know 20 cube = 8000 and 30 cube = 27000
    So our cube root lies between these two that is 20 or 30
    As we know that the unit digit should be 8 , the answer is 28
    Q) Find out the cube root of 250047 ?
    Ans) STEP 1 : The unit digit of cube = 7 therefore unit digit of cube root = 3
    STEP 2 : Group the cube…into 250 and 047. So the cube root has 2 digits
    STEP 3.Finally, we know that 60 cube = 216000 and 70 cube= 343000
    250047 lies between 216000 and 343000
    Therfore the cuberoot should lie between 60 and 70
    We know that unit number should be 3
    Therefore the number is 63
