Brief Fact About This Mcq:

The Osborne 1 is the first commercially successful portable computer, released on April 3, 1981 by Osborne Computer Corporation. The Osborne 1 weighs 24.5 lb (11.1 kg), cost US$1,795, and runs the CP/M 2.2 operating system. It is powered from a wall socket, as it has no on-board battery, but it is still classed as a portable device since it can be hand-carried when packed. The computer shipped with a large bundle of software that was almost equivalent in value to the machine itself, a practice adopted by other CP/M computer vendors. Competitors quickly appeared, such as the Kaypro II.
