Internal computer components [Unit 2 - task 1]
The document discusses several key components of a computer's motherboard including the power supply, motherboard, CPU, northbridge, southbridge, and the three major cards (modem, sound, and video). It also covers the functions of RAM, ROM, and disk drives.
Memory devices
Memory devices can be categorized as primary storage or secondary storage. Primary storage includes RAM and ROM. RAM is used to temporarily store data and programs being processed by the CPU. ROM permanently stores basic input/output programs like the BIOS. Secondary storage devices store data externally and include USB flash drives, external hard disks, optical disks like CDs/DVDs, memory cards, and online storage services. Common online storage services are DriveHQ, Dropbox, OpenDrive, SpideOak, and ZumoDrive.
Parallel computing
Parallel computing involves breaking problems into discrete parts that can be solved concurrently using multiple processors. There are different forms of parallel computing including bit-level, instruction-level, data, and task parallelism. Parallel computing allows solving larger and more complex problems faster while making better use of underlying parallel hardware through sharing memory and resources across processors.
Memory & storage devices
The document discusses the differences between computer memory and storage. It defines memory as temporary data storage that exists on chips, while storage refers to long-term data storage on tapes or disks. It describes primary memory (RAM) as volatile memory that allows quick access to data but must be constantly powered, while secondary storage (hard disks, optical disks) allows permanent long-term storage but is slower to access. The document provides examples of different types of memory chips (ROM, RAM) and storage devices (hard disks, optical disks).
Memory devices
Memory devices can be classified in several ways:
1. By location as registers, main memory, and secondary memory. Registers are inside the CPU while main memory is external but faster than secondary memory like hard disks.
2. By access as sequential (location must be accessed in order) vs random access memory (RAM) which allows random access.
3. As static (maintains data without refresh) vs dynamic RAM which must be periodically refreshed.
4. As volatile (loses data on power off) vs non-volatile like ROM and magnetic storage.
Read-only memory (ROM) is non-volatile and only allows reading. It is used to permanently store information. Various RO
Describe primary and secondary memory inc
Primary memory like RAM can be read and written to and is used to store operating systems and active programs and files. ROM is read-only and stores boot programs. Secondary storage like hard disks and USB drives stores inactive programs and files long-term as it is non-volatile. Buffers temporarily store data during transfers between devices like printers and memory that operate at different speeds, allowing the processor to do other tasks, while interrupts signal the processor to refill buffers.
Component presentation
The motherboard connects all components in a computer and contains slots for the CPU, RAM, graphics card, and connections for other components like storage drives and power supply. The CPU processes data and has a fan to prevent overheating. RAM temporarily stores data for the CPU and determines performance. Hard drives permanently store large amounts of data that can be accessed through the operating system. Graphics cards display visuals on the computer and better ones allow for gaming. Power supplies take electricity from wall outlets and distribute different voltages to components through cables.

Learning theory - Constructivism
Constructivism is a learning theory developed by psychologists including Piaget, Bruner, Vygotsky, and Dewey. It proposes that people build their understanding of concepts over time through experiences and interactions with their surroundings. By this view, learning involves constructing one's own knowledge instead of just receiving information. Constructivism also holds that as people age and develop, their ways of thinking and learning change through experience. In a classroom, teachers aim to support students in understanding concepts and becoming expert learners, while students explore and discover new information with guidance from teachers.

Primary memory (RAM and ROM) allows direct CPU access but loses data when powered off, while secondary memory (hard disks, USB drives, etc.) permanently stores data but requires copying to primary memory for CPU access. Primary memory is volatile and internal, while secondary memory is non-volatile and external. Together they provide data storage and retrieval capabilities essential for computer functioning.

Backing storage media
Storage devices are a evolving nowadays, especially because our storage appetites are growing every second. The presentation talks about various types of storage, why it is used, and basically, the advantages and disadvantages of the storage discussed.
COMPUTER MEMORY
Computer memory is used to store data and instructions and can store both input and output. There are two main types of computer memory: primary and secondary. Primary memory, also called main memory, is semiconductor-based and volatile, storing data and programs temporarily while the computer is on. It includes RAM and ROM. RAM is used for running programs and can be static RAM (SRAM) or dynamic RAM (DRAM). ROM is non-volatile and stores the basic instructions for starting the computer. Secondary memory is non-volatile storage like hard disks, floppy disks, CDs, DVDs, flash drives, and SD cards, which can store large amounts of data and is accessed by transferring data to primary memory.
Introduction to computer hardware

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Internal components non tchnical
- 2. Contents page Intro Motherboard over view
- 3. Intro In this PowerPoint I am going to explain the functions of the different components like the CPU, power unit in a very basic non technical way.
- 4. Mother board Themother board consists of multiple components but its is the main part of the computer, the components involved include: CPU, north bridge, south bridge, GPU.
- 5. CPU TheCPU (central processing unit) is essentially the brain of the computer it controls every decision made and reacts to every thing you do on your pc. Lots of CPUs now are dual core which means there are two chips on the CPU this obviously means batter results from the computer.
- 6. North bridge and south bridge (short description) The function of the north bridge was : to control the communication between RAM and AGP The function of the south bridge was : to control the binary functions of the USB, bios, PCI, ISA, IDE and legacy These were their functions until they were put into the actual CPU in 2011
- 7. GPU TheGPU (graphics processing unit) is the part that puts images on your screen it is also used in things like phones and game consoles. They basically interpret the code into the image you see in front of you.
- 8. Memory In the memory there are these main types: ram, rom, flash memory and hard drive.
- 9. RAM RAM: this stands for (random access memory) this is a form of computer data storage and is usually in the form of integrated chips. It lets you access memory in bursts, the modern types of RAM/DRAM are no longer random access but the name stuck for no particular reason, it is associated with volatile types of memory because it loses memory when power is lost volatile memory or volatile storage is a form of memory component that requires power to store data.
- 10. ROM ROM: this stands for (read only memory) it usually cannot be edited but can either very slowly or with extreme difficulty because of the property of being difficult it is usually used in firmware which is attached to types of hardware so basically it is used in software needed for hardware for instance it is widely used in TV remote s it has been used in consumer products since the 1970's, it is also the oldest form of solid state, solid state is basically a disk that doesn’t move but can still be read by lasers.
- 11. Flash Memory Flashmemory: is non volatile data storage which means it can hold data without power, the information on it can be deleted electronically, the NAND types of memory include most types of widely used forms of data storage for PC's these include memory cards (increase the storage size), USB flash drives (memory sticks), solid state drives (SSD)
- 12. Hard Drive Hard drive: first invented in 1954 hard disk drives are a non volatile type of data storage it is the primary form of storage for every PC they consist of one or more rapidly rotating discs covered in a magnetic material and magnetic heads arranged to transfer data onto the surface of the disc and to read data from it, they are categorized as random access, digital, magnetic, through the years they have decreased in size but increased in the size of storage. The original storage size was 5 million 6-bit characters and now they are are much more efficient in storage size.
- 13. Power unit This does exactly what it sounds like it is for the input of power and distributing it amongst the units. It has a built in fan so that it does not over heat if the components within it were to over heat it would stop the whole computer would crash.
