Computers are key components of the world of today. They play a very important role in education, business, economic, and many other fields.
Let's get to know more about them!
This document provides an overview of computers, operating systems, and networks. It describes the basic components of a computer including the central processing unit, input/output devices, and memory. It then discusses operating systems and their functions like input/output management, memory allocation, and mass storage. Finally, it covers different types of computer networks including personal area networks, local area networks, and wide area networks. It also describes common network topologies like bus, ring, star, tree, and mesh configurations.
The document discusses the five generations of computers from the 1940s to present. The first generation used vacuum tubes and magnetic drums. The second generation used transistors, allowing computers to become smaller, faster, and more efficient. The third generation used integrated circuits, making computers accessible to a mass audience. The fourth generation used microprocessors on a single chip, allowing computers to fit in the palm of the hand. The fifth generation, still in development, is based on artificial intelligence.
Computer architecture defines the conceptual design and operational structure of a computer system. It includes components like the CPU, memory, registers, and buses that connect them. The CPU contains the control unit and ALU to execute instructions. Memory is divided into main memory (RAM and ROM) for active use, and secondary storage for permanent storage. Registers are high-speed memory locations within the CPU. Buses provide communication between components using address, data, and control lines. Together these components form the fundamental architecture that allows a computer system to function.
This document provides an overview of the history and development of computer architecture. It begins with some of the earliest computing devices like the abacus and ENIAC, the first general-purpose electronic digital computer. It then discusses the evolution of CPU and memory architecture from vacuum tubes to integrated circuits and microprocessors. The document outlines different bus architectures like ISA, EISA, MCA, PCI, and AGP that were used to connect components. It also reviews memory hierarchies and I/O interfaces like IDE, SCSI, serial ports, USB, and parallel ports. The presentation aims to trace the progression of computer hardware technology over time.
This document provides an overview of computer architecture and organization. It discusses the different levels of representation from high-level programming to machine language. It also covers the main components of a computer system, including the processor, memory, and input/output devices. Memory has a hierarchy, with cache being fast but expensive and main memory being slower but able to store more data. Input/output devices have a variety of speeds and requirements that make their organization complex.

This document provides an overview of computer organization and architecture. It defines computer architecture as consisting of an instruction set architecture (ISA) and machine organization. The ISA defines the logical view of the underlying hardware for executable programs, while machine organization describes the physical implementation of the ISA. The document also discusses the Von Neumann architecture, which is the basic design model for modern computers consisting of a processor, memory, and I/O. The processor contains an ALU, control unit, and registers, while the memory subsystem stores both programs and data.
This presentation discusses various computer input, output, and storage devices. It covers common input devices like keyboards, mice, microphones, and cameras. Output devices discussed include monitors, printers, and speakers. The central processing unit and memory are also summarized, including the CPU components like the ALU and control unit. Registers in the CPU and different types of computer memory are defined.
This document discusses multicore and shared multiprocessor systems. It describes shared memory multiprocessors (SMP) which provide a single shared physical address space across multiple processors. SMPs allow processors to communicate through shared memory and access any memory location. SMPs can be uniform memory access (UMA) where memory latency is equal, or non-uniform memory access (NUMA) where latency depends on processor-memory location. Synchronization is needed when sharing data, and locks are used to allow only one processor access at a time. OpenMP is an API that makes it easy to parallelize loops across processors in SMP systems.
The document discusses key topics in computer architecture including instruction set architecture, pipelining, memory hierarchy, parallelism, and performance evaluation metrics. It notes that computer performance is measured by execution time, throughput, or latency. Trends show that logic, DRAM, and disk capacities double every 2-3 years while speeds improve more slowly. Amdahl's Law and the CPI equation are introduced as quantitative principles for evaluating performance improvements and tradeoffs.
Hyper-threading technology allows a single processor to appear and function as multiple processors. It was first implemented in 2002 in Intel Pentium 4 Xeon processors. Hyper-threading works by dividing processor workload into threads that can be executed concurrently on different processor execution units. This makes more efficient use of processor resources and improves performance on multi-threaded software. While it increases throughput, shared processor resources between threads can also lead to conflicts that result in reduced performance in some cases.
The document discusses the evolution of computer systems from the first generation to the sixth generation. It describes the key technologies that defined each generation as well as representative computer systems. It also covers Moore's Law and defines it as the observation that the number of transistors on integrated circuits doubles every 18 months.

Digital Banking in the Cloud: How Citizens Bank Unlocked Their MainframePrecisely
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
