These days there is no work without computers, if there is a small network problem in the company, all the employees feel like a rainy day for the students in the school. No emails, No internet blah blah...
Computers have influenced so much in human life, the computers have got its evolutionary stages in many ways, one of those are the portables computers or we call it in modern days Lap-Top, why do we call it lap-top? because we use it top of our laps similar to the palm-tops... ( I know what you guys are thinking... "Huh big deal")
The first computer is big as a car garage as we already know but I wanted to know how did the first Lap-Top look like... here are some information i found in the net... sharing with you all :-)
The IBM 5100 is the first portable computer, which was released on September 1975. The computer weighed 55 pounds (25 Kg) and had a five inch CRT display, tape drive, 1.9MHz PALM processor, and 64KB of RAM. In the picture to the right, is an ad of the IBM 5100 taken from a November 1975 issue of Scientific America.
The first truly portable computer or laptop is considered to be the Osborne I, which was released on April 1981. The Osborne I was developed by Adam Osborne and weighed 24 pounds, had a 5-inch display, 64 KB of memory, two 5 1/4" floppy drives, and a modem.
The IBM PC Division (PCD) later released the IBM portable in 1984, it's first portable computer that weighed in at 30 pounds. Later in 1986, IBM PCD announced it's first laptop computer, the PC Convertible, weighing 12 pounds.
