2. WHAT IS SOFTWARE
• Computer software, or simply software is any set of machine-readable instructions that
directs a computer processor to perform specific operation.
• Computer hardware and software require each other and neither can be realistically used
without the other.
• Software is stored in computer memory and is intangible, i.e. it cannot be touched.

3. HOW IT WORKS
• Microprocessors understand only machine language
• A compiler translates high-level language instructions to object code (machine language
instructions)
• Computer perform operation based on instruction writen

4. HOW IT MADE
• Programming Language
• Low Level – Close to machine language
• High Level - Close to human language
• Scripting – Need interpreter when executed
• Compiler – Tool to translate high-level language instructions to object code (machine
language instructions)
• Integrated Development Environment – Environment or tool where programmer create a
software
• Methodology – The standard process of creating software from requirement until
deployment

5. TYPES OF SOFTWARE
• System Software
• Designed to directly operate the computer hardware, to provide basic functionality
needed by users and other software, and to provide a platform for running application
software
• Application Software
• A computer program designed to help people perform an activity
• A set of one or more programs designed to carry out operations for a specific
application. Application software cannot run on itself but is dependent on system
software to execute. Examples of application software include MS Word, MS Excel, a
console game, a library management system, a spreadsheet system etc.

6. SYSTEM SOFTWARE
• Operating systems,
• Essential collections of software that manage resources and provides common
services for other software that runs "on top" of them.
• Supervisory programs, boot loaders, shells and window systems are core parts of
operating systems.
• In practice, bundled with additional software (incl. application software) so that a user
can do some work with a computer that only has an operating system.
• Device drivers,
• Operate or control a particular type of device that is attached to a computer.
• Utilities,
• computer programs designed to assist users in maintenance and care of their
computers.

8. MIDDLEWARE
• Middleware is a computer software that provides services to software application beyond
those available from the operating system.
• Middleware makes it easier for software developers to perform communication and
input/output, so they can focus on the specific purpose of their application
• Middleware is the software that connects software components or enterprise applications
• Middleware is the software layer that lies between the operating system and the
applications on each side of a distributed computer network. Typically, it supports
complex, distributed business software applications

9. LICENSES
• Proprietary Software License
• Software publisher grants the use of one or more copies of software under the EULA
• Licensing Model
• Per user (named user, client, node)
• Per concurrent/floating user
• Per Resource used or managed
• Open License Program (OLP), Transactional License Program (TLP), Volume
License Program (VLP)
• Original Equipment Manufacture (OEM)
• Contractual License Program (CLP)
• Free and Open Source Software License
• Shareware
