This computer was designed for a single individual and thus the term, personal computer. Personal computers were used by employees in various roles including scientists and secretaries at Xerox. The Xerox Alto was the first computer to use a mouse. Additionally, the Ethernet was used to network the computers at Xerox. The CPU was the size of a small refrigerator and was designed to find under the desk with the mouse and keyboard on the desk.
Chapter 1 Introduction The Linux was developed in the early 1991s by Linus Torvald. Linus Torvald developed first version of Linux as an operating system for the Intel 80386 microprocessors. Linux is fast, stable and open source operating system for PC computer system .The Linux operating system has become one of the major Linux distribution, complete set of internet applications and fully functional desktop interface. Linux is being adopted as the operating system in many products beyond its traditional applications. Today, Linux is ready to accept challenge .Today Linux is a fully-fledged operating system and it is mainly running on Alpha, ARM, PowerPC, SPARC, X86-64 and many other architectures.
Summary This report will discuss solid state technology, particularly the architecture used to communicate between memory modules and the main processor of a computer system. It will highlight and describe the many benefits of SSD technology. Solid state technology is not a new thing, a solid state device may contain any electrical parts that do not have a mechanical action i.e no moving parts. These parts can consist of transistors (mainly!) microprocessor chips, many types of flash memory and diodes.
To have the parts it needs at the right time to assemble a PC, Dell has to ensure everything is planned and coordinated smoothly through its internal IT systems and via electronic linkages with suppliers, its own logistics hubs, shipping companies, and distributors who handle third party items. Sales and marketing One-third of Dell’s employee base is in sales and marketing. Initially the company had sales and service representatives but once Dell’s operations were introduced to the internet, everything is handled online. External Relationships: From Value Chain to Value Web Dell’s core PC business was organized along the lines of a traditional value chain. Like most other PC companies, it concentrated on building and selling systems, relying on others to provide components, software and services.
2. Allocating enough memory necessary for each process to efficiently run and use different types of system memory. 3. The operating system manages all hardware not found on the computer 's motherboard through driver programs. Drivers provide a way for applications to use hardware subsystems without having to know all the details of the hardware operation.
1.1.4 I/O Virtualization It’s a technology that brings that same augmented resource utilization and flexibility of the network infrastructure. I/O Virtualization architecture comprises of: a) Virtual Device b) Guest Driver c) The communication mechanism between virtual device and stack of virtualization. d) Real Device e) Physical device driver f) Virtualization I/O stack I/O virtualization technology can be used to visualize a single physical adapter and for multiple virtual network interface cards (vNICs) and virtual host bus adapters (vHBAs). vNICs and vHBAs function like any other NIC and HBA card installed on the server. They work along with Hypervisor and applications which is the existing operating systems.
5.2 SOFTWARE According to Jolli Ballew (2017) stated that software, in broad terms, is a set of instructions (generally referred to as code), that is positioned between you and the device’s hardware, enabling you to use it. But what is computer software, really? In layman’s terms, it’s an invisible component of a computer system that makes it possible for you to interact with the computer 's physical components. Moreover, software is what allows us to communicate or use with smartphones, tablets, media players, and similar other devices. Software also allows the hardware to process the data for the user.
All the advanced processors are microprocessors meaning that multiprocessors could be contained on a single chip. So, the chip forms the basic building block of microprocessors in modern digital computers. Advanced Processors: According to Moore’s law, “Integrated Circuit (IC) resources double approximately every 2 years”. And also the power limit has forced a dramatic change in the design of microprocessors. Rather than continuing to decrease the response time of a single program running on a single processor, microprocessors with multiple processors per chip have started to emerge as advanced processors where the benefit is often more on throughput than on response time.
We can say it is Nano science which help us to see and work with things in Nano scale, Nano science and nanotechnology involve the ability to see and to control individual atoms and molecules. Definition of Nanotechnology: it is a branch of technology which deals with small dimensions less than 100 nanometers, especially the manipulation of individual atoms and molecules. The Start of Nanotechnology: 1965: Intel co-founder Gordon Moore described in Electronics magazine several trends he foresaw in the field of electronics. One trend now known as “Moore’s Law,” described the density of transistors on an integrated chip (IC) doubling every 12 months, Moore also saw chip sizes and costs shrinking with their growing functionality—with a transformational effect on the ways people live and
Windows 2 It was released in 1987, two years after the emergence of windows 1. Its big innovation was that, windows could overlap each other and it could also introduce the ability to minimize and maximize windows instead of zooming. Control panel where various system setting
