This document discusses different types of software and hardware used in computer networks. It defines network software as applications running on one host to communicate with applications on another host. It also defines system software as programs that control computer hardware operations and help other programs run correctly. Application software performs specific tasks for users. The document also distinguishes hardware as physical electronic devices, software as programs running on hardware, and firmware as low-level software tied to hardware control and updated less often than other software.

2. Network Software
A network application is any application running on one host providing
communication to another application running on a different host.
Network applications allow network operators to easily manage and
monitor network traffic as well as analyze data that can be used to
improve network systems.
What is System Software?
System Software is a set of programs that control and manage the
operations of computer hardware. It also helps application programs to
execute correctly.
What is an Application Software?
Application Software is a program that does real work for the user. It is
mostly created to perform a specific task for a user.
KEY DIFFERENCES:
• System software are designed to manage the resources of the
system, like memory and process management, security, etc.
whereas Application software are designed to fulfil the
requirements of the user for performing specific tasks.
• The System Software is a general-purpose software while the
Application Software is specific purpose software.
• System Software is written in a low-level language like a machine
or assembly language but Application software is a high-level
language is used to write Application Software.

3. • System Software is capable of running independently while
Application software can't run independently.
• The System Software starts running when the system is powered
on and runs until the system is powered off while the Application
Software starts when the user begins, and it ends when the user
stops it.
• System software are independent of the application software while
an Application software needs system software to run.
Hardware
Hardware is any physical electronic device. Computers, adapter cards
and Ethernet cables are examples.
Software
Software is a broad term for the programs running on hardware.
Familiar kinds of software are operating systems, which provide overall
control for computer hardware, and applications, which are optional
programs used for a particular job. Software resides on disks and is
brought into memory when it is needed.
Firmware
In computing, firmware is a specific class of computer software that
provides the low-level control for a device's specific hardware.
• Software is the most temporary and malleable. Firmware is semi-
permanent software that’s tied more directly to the hardware and
updated less often, and hardware is the physical components that
are most permanent.
