Lecture 4
Understanding Computing Types of Computing
Analog Computing: Perform operations by continuous physical phenomena, like using
the voltage of a circuit. These are used in specialized applications for tasks like
scientific simulations.
Digital Computing: Processes discrete data represented by binary values (0s and 1s).
This is the most common type of computing used in modern devices, such as PCs,
smartphones, and servers.
Hybrid Computing: Combines features of both analog and digital computers. For
example, a hospital's intensive care unit (ICU) monitor uses analog sensors to measure
a patient's vital signs and then converts them into digital data for processing and
display.
Understanding Computing
Cloud Computing
https://www.spiceworks.com/tech/cloud/articles/what-is-cloud-computing/
Cloud computing refers to the use of
hosted services, such as data storage,
servers, databases, networking, and
software over the internet. The data is
stored on physical servers, which are
maintained by a cloud service provider.
a)infrastructure-as-a-service (IaaS)
b)platform-as-a-service (PaaS) and
c)software-as-a-service (SaaS)
Computing Accessories and Peripherals
Computer hardware includesInput and output devices,CPU,RAM,SSD&HDD,Motherboard,etc.
•Input device sends the data into the computer system. It allows users to interact with the
computer Ex: Keyboard, Mouse, Monitor, Scanner, Joystick, etc.
•Output device is a device used to send data from the computer to the user. In short, it provides
output to the user so that the user can communicate with it—for example Monitor, Printer,
Speaker, etc.
•CPU is a Central Processing Unit which is a hardware device that is placed in a motherboard.
“Brain of the Computer”.
•RAM is a “Random Access Memory” hardware device placed within the motherboard. RAM is
used to provide the storage to run the application in your computer. It is the primary memory of
the computer system.
•SSD and HDD both are the storage devices of the computer, and it is secondary memory of the
computer system. SSD stands for “Solid State Drive” & HDD stands for “Hard Disk Drive”, both are
hardware device which is used to provide storage so that the user can easily store anything like:
Software, Videos, Images, etc, and so on

Operating System
✓An operating system (OS) is a fundamental software that manages computer
hardware, software resources, and provides various services for computer
programs.
✓Acts as intermediary between users and the computer hardware, enabling
them to interact with and utilize the system's capabilities.
Examples of Popular Operating Systems:
•Windows: Developed by Microsoft, Windows is a widely used OS for personal
computers, laptops, and servers.
•macOS: Developed by Apple, macOS is the OS used in their desktop and laptop
computers.
•Linux: Linux is an open-source OS kernel used as the basis for various Linux
distributions (distros) like Ubuntu, CentOS, and Debian.
•Android: Developed by Google, Android is an open-source mobile OS used in
