Computer software is a set of machine-readable instructions that directs a computer processor to perform tasks. Software requires hardware to function and is intangible, stored in computer memory. It is created through programming languages and compiled into machine-readable code. There are two main types: system software that operates hardware and provides functionality, and application software for specific tasks like word processing. Software is licensed through proprietary licenses or open source licenses and comes in various models like per user or concurrent user.

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
