First Generation(1946-1959)
• First generation of computers started with using vacuum
tubes as the basic components for memory and circuitry
for CPU (Central Processing Unit).
• Punched cards, Paper tape, Magnetic tape Input & Output
device were used.
• There were machine codes and electric wired board
languages used.
• In this generation, mainly batch processing operating
systems were used.
ENIAC
• Full name- Electronic Numerical Integrator and Computer.
• Developed by John Presper Eckert and John W. Mauchly.
• First fully electronic general purpose computer.
EDVAC
• EDVAC (Electronic Discrete Variable Automatic Computer) was to be
a vast improvement upon ENIAC.
• Eckert and Mauchly teamed up with the mathematician John von Neumann
to design EDVAC, which pioneered the stored program.
UNIVAC
• Universal Automatic Computer, the UNIVAC -I, a first commercial computer
developed by J. Presper Eckert and John Mauchly.
Second Generation(1959-1965)
• This generation using the transistor were cheaper, consumed less
power, more compact in size, more reliable and faster than the first
generation Computers.
• In this generation, magnetic cores were used as primary memory and
magnetic tape and magnetic disks as secondary storage devices.
• In this generation, assembly language and high-level programming
language like FORTRAN, COBOL were used.
• Punched cards, Paper tape, Magnetic tape Input & Output device
were used.
• There were Batch processing and Multiprogramming Operating
system used.

When a user purchases software ____ is actually
purchased.

Types of Software Licenses
• A Concurrent license that is based on the number of
simultaneous users accessing the program. It typically
deals with software running in the server where users
connect via the network.
• A volume license key (VLK) denotes the product key
used when installing software licensed in bulk, which
allows a single product key to be used for multiple
installations.
• Multi-licensing is the practice of distributing software
under two or more different sets of terms and
conditions. This may mean multiple different software
licenses or sets of licenses.
Software

Software Conversions
• A pilot conversion is a hardware or software
migration method that involves rolling out the
new system to a small group of users for testing
and evaluation.
• Big bang adoption is a hardware or software
migration method that involves getting rid of the
existing system and transferring all users to the
new system simultaneously.
Software Conversions
• Parallel adoption is a method of hardware
or software migration that involves using the
existing and new systems simultaneously
until the implementation is judged to be
complete and satisfactory.
