1.Internal components are the devices that are inside the main computer tower. These devices include the Central Processing Unit (CPU), Motherboard and the modem.
Computer Hardware is the physical part of a computer, as distinguished from thecomputer softwarethat executes or runs on the hardware. The hardware of a computer isinfrequently changed, while software and data are modified frequently. The term "soft" refers to readily created, modified, or erased. Theseare unlike the physical components within the computer which are "hard".
Inside Computer
Motherboard
The motherboard is the "body" or mainframe of the computer, through which all other componentsinterface. It is thecentral circuit board making up a complex electronic system. A motherboard provides the electrical connections by which the other components of the systemcommunicate. The mother board includes many components such as: centralprocessing unit (CPU), random access memory (RAM), firmware, and internal and external buses.
Motherboard
Central Processing Unit
The Central Processing Unit (CPU; sometimes just called processor) is amachine that can executecomputer programs It is sometimes referred to as the "brain" of the computer.
CPU Diagram
There are four steps that nearly all CPUs use in their operation:fetch, decode, execute, and writeback. The firststep, fetch, involves retrieving an instruction from program memory. In thedecode step, the instruction is broken up into parts that have significance toother portions of theCpu. During the execute step various portions of the CPU such as the arithmeticlogic unit (ALU) and thefloating point unit (FPU) are connected so they can perform the desired operation. The final step, writeback, simply "writes back" the results of the execute step to some form of memory.
Random Access Memory
Random access memory (RAM) is fast-access memory that is cleared when the computer is power-down. RAM attaches directly to the motherboard, and is used to store programs that are currently running. RAM is a set of integrated circuits that allow the stored data to be accessed in any order (why it is called random). There are many different types of RAM. Distinctions between these different types include: writable vs. read-only, static vs. dynamic, volatile vs. non-volatile, etc.
RAM
Firmware
Firmware is loaded from the Read only memory (ROM) run from the BasicInput-Output System (BIOS). It is a computer program that is embedded in a hardware device, for example a microcontroller. As it name suggests, firmware is somewhere between hardware and software. Like software, it is a computer program which is executed by a microprocessor or a microcontroller. But it is also tightly linked to a piece of hardware, and has little meaning outside of it. Most devices attached to modern systems are special-purpose computers intheir own right, running their own software. Some of these devices store that software ("firmware") in a ROM within the device itself
Power Supply
The power supply as its name might suggest is the device that supplies power to all the components in the computer. Its case holds a transformer, voltage control, and (usually) a cooling fan. The power supply converts about 100-120 volts of AC power to low-voltage DC power for the internal components to use. The most common computer power supplies are built to conform with the form factor. This enables different power supplies to be interchangable with different components inside the computer. ATX power supplies also are designed to turn on and off using a signal from the motherboard, and provide support for modern functions such as standby mode.
Removable Media Devices
If your putting something in your computer and taking it out is most likely a form of removable media. There are many different removable media devices. The most popular are probably CD and DVD drives which almost every computer these days has at least one of. There are some new disc drives such as Bl
computer consists of four major parts: the input, output, CPU (central processing unit), and memory. Input consists of anything you will add into the computer (microphone, keyboard, mouse, scanner), and output is how the computer gives back to you (think screen, speakers, etc.).
C Programming Language is the most popular computer language and most used programming language till now. It is very simple and elegant language. This lecture series will give you basic concepts of structured programming language with C.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

1. TERMS RELATED TO COMPUTER
“HARDWARE”
By
Mr. V. VEERANAN
M.Sc. Computer Science., Dip. in Yoga.,
Government Arts College, Melur – 625 106.
2. 1.1.5 Terms related to Computer
1.1.5.1 Hardware
These computer science terms connect to the
physical components of a computer. Hardware represents
the most tactile aspects of computer science and the
materials computers are made of.
Mr. V.Veeranan, M.Sc. Computer Science, Dip. in Yoga
3. CPU
CPU stands for the Central Processing Unit. It is
the processing chip that serves as the "brains" of a device
that interprets (or processes) the digital instructions
provided by applications.
Mr. V.Veeranan, M.Sc. Computer Science, Dip. in Yoga
4. Bit
Bit is an abbreviation for ”binary digit” the
smallest piece of information used by a computer. Each bit
is either a 1 or a 0, which are the binary digits that make
up computer language. Bits are literally the foundation
upon which computer science is built. In modern computing,
information is stored and processed at a scale that is
orders of magnitude larger than individual bits.
Mr. V.Veeranan, M.Sc. Computer Science, Dip. in Yoga
5. See the conversion rate below to better
contextualize the size of a bit:
1 Byte = 8 bits
1 Kilobyte = 1,024 bytes
1 Megabyte = 1,024 kilobytes
1 Gigabyte = 1,024 megabytes features.
Mr. V.Veeranan, M.Sc. Computer Science, Dip. in Yoga
6. RAM
Random Access Memory (RAM) is the hardware
component used to store data that is actively being used by
a processor. When needed, information flows to RAM
storage from long-term secondary storage—typically a hard
drive.
Mr. V.Veeranan, M.Sc. Computer Science, Dip. in Yoga
7. Secondary storage
Secondary storage refers to the long-term data
storage options found in a device. This includes Hard Disk
Drives (HDD) and Solid-State Drives (SSD). When you
save a file to your computer, it is sent to secondary storage.
Mr. V.Veeranan, M.Sc. Computer Science, Dip. in Yoga
8. ROM
ROM stands for Read-Only Memory. This is
memory that can only be read from and is not electronically
modifiable after being manufactured. Computers use ROM
to store critical foundational information like start-up
processes and software instructions.
Mr. V.Veeranan, M.Sc. Computer Science, Dip. in Yoga
9. Input / Output Devices (I/O Devices)
I/O devices refer to anything people use to input
information to the computer or to take information out
(output). For example, a keyboard and Mouse are input
devices. A printer is an output device.
