Understanding Computer Components, System, Devices and Peripherals
Lesson Objectives:
1. Identify the key components of a computer system (CPU, memory, storage, I/O devices).
2. Recognize and categorize different types of devices (input, output, storage, and network).
3. Demonstrate basic troubleshooting skills for connecting and configuring peripherals.
COMPONENTS OF COMPUTER SYSTEM
Software
Software is a set of instructions, data or programs used to operate computers and execute specific tasks. https://www.techtarget.com/searchapparchitecture/definition/software
System Software
System software is a program designed to run a computer's hardware and applications and manage its resources, such as its memory, processors, and devices.
The digital computer is outlined to execute calculations and logical operations at a high pace. Such computers are proficient in solving problems in discrete formats. It acquires the raw data as input is in the form of digits/binary numbers (i.e 0 and 1) and processes it with programs stored in its memory to produce the output.
It can implement arithmetic operations such as addition, occurrence, subtraction, multiplication and division, and all sorts of logical/mathematical operations as well. All modern computers like laptops, desktops including smartphones, calculators, tablets, digital watches, accounting machines, workstations, digital clocks etc. that we use at home or office are digital computers. https://testbook.com/computer-awareness/types-of-computer
Digital computers are either general purpose computers or special purpose ones. Special purpose computers, as their name suggests, are designed for specific types of data processing while general purpose computers are meant for general use.
Application Software
Hybrid computers are computers that exhibit features of analog computers and Digital computers. The digital component normally serves as the controller and provides logical and numerical operations, while the analog component often serves as a solver of differential equations and other mathematically complex equations.
It is fast like an analog computer and has memory and accuracy like those of digital computers. It can process both continuous and discrete data. It takes analog signals and transforms them into digital form before processing them.
These types of computers are extensively used in specialized applications where both analog and digital data are processed. For example, a processor is applied in petrol pumps that converts fuel flow measurements into quantity and price. Furthermore, they are used in aeroplanes, hospitals, and scientific applications. https://testbook.com/computer-awareness/types-of-computer

Software
Operating System
An operating system (OS) is the program that, after being initially loaded into the computer by a boot program, manages all of the other application programs in a computer. https://www.techtarget.com/whatis/definition/operating-system-OS
An operating system or OS is software installed on a computer's hard drive that enables the computer hardware to communicate and operate with the computer software. Without a computer operating system, a computer and software programs would be useless. https://www.computerhope.com/jargon/o/os.htm
FUNCTIONS OF OPERATING SYSTEM
There are many different functions and tasks an operating system performs on a computer; some of these include the following.
Manage all of the computer hardware inside your computer and all of the connected peripherals.
Manage all of the software and communication between software programs installed on the computer.
Handle all of the data generated by the software.
