The document summarizes the main physical components of a personal computer:
1. The case houses the power supply, storage devices, and motherboard. It contains slots for expansion cards and buttons for power and reset.
2. The motherboard connects the main internal components like the processor, memory, and expansion slots. It transmits signals between components.
3. Storage devices like hard drives use magnetic disks to store data in a mass storage format. Solid state drives may replace hard drives in the future.

This chapter teaches the components that make up a personal comput.docxrhetttrevannion
This chapter teaches the components that make up a personal computer. A personal computer comprises many components, most notably the CPU, motherboard, RAM, hard disk, removable media, and input/output devices.
Identify the functions of the hardware in a computer system:
· Motherboard is an important computer component because it's what everything else connects to! The motherboard is a decently sized circuit board that lets other components communicate.
· Central Processing Unit (CPU)
is referred to as a computer's brain and is the machine's workhorse. It performs the calculations needed by a system and can vary in speed.
· Random-access Memory (RAM)
is temporary memory.
· Graphics Card- The major work of the graphics card is to create graphics and images that can be shown on a monitor. If your computer does not have a graphics card, you will not see the data, and the computer would be useless.
· Hard Drive- Hard drive would be another component of a computer. A hard drive is used to store programs and files on your computer.
· Network Card- A network card would be a separate card or integrated into the motherboard. The major work of a network card is to enable your computer to connect to the network and Internet.
· Monitor- It is an important component of the computer. Even though the computer is great, without a monitor, it also would be useless.
· USB Ports- USB port is also one of the most important computer components. The USB port enables you to connect some computer accessories, such as a mouse, keyboard, external hard drive, etc. So, it would be an essential part of the computer.
Computer hardware (usually called
hardware when a computing context is concerned) is the collection of physical elements that constitutes a computer system. Computer hardware is the physical parts or components of a computer, such as a monitor, mouse, keyboard, computer data storage, hard disk drive (HDD), graphic cards, sound cards, memory, motherboard, etc., which are tangible, physical objects. In contrast, the software is instructions that can be stored and run by hardware.
Software is any machine-readable instruction that directs a computer's processor to perform specific operations. A combination of hardware and software forms a usable computing system.
Von Neumann Architecture Scheme
The template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms.[3] The term's meaning has evolved to mean a stored-program computer where an instruction fetch and a data operation cannot co.

I hope you will enjoy this and it will help you to clear about you'r thinking on not only workstation but also the other IT product and the competitive market with Dell and Lenovo.
The basic parts of a desktop computer are the computer case, monitor, keyboard, mouse, and power cord. Each part plays an important role whenever you use a computer.
The most basic computer setup usually includes the computer case, monitor, keyboard, and mouse, but you can plug many different types of devices into the extra ports on your computer. These devices are called peripherals. Let's take a look at some of the most common ones.
The computer case is the metal and plastic box that contains the main components of the computer, including the motherboard, central processing unit (CPU), and power supply. The front of the case usually has an On/Off button and one or more optical drives.
1. PC ‘S PHYSICAL COMPONENTS
THE CASE
The case is the frame into which they are installed the main components of a computer. The houses usually have in their upper or lower housing for
the power supply, in the middle of different accommodation to contain storage devices and reading, while at the bottom there are slots that serve
as output for the hardware that is use of PCI slots. The motherboard is mounted on the right panel. In front of the case is generally present the
power button on and off, accompanied by the reset button that allows you to restart the PC. Some homes are equipped with instruments for
measuring the temperature inside the PC or the measurement of the speed of calculation of the processor. Usually the panel that allows the display
of these data is located in the upper part of the case.
THE MAIN BOARD
The motherboard or system board is an essential part of a modern personal computer in the form of the main electronic board brings together all
the electronic circuitry and interface connections between the various main internal components of the PC. Comprising therefore also the
expansion bus and the interfaces to the outside. It is therefore responsible for the transmission and correct timing of many hundreds of different
signals, all high-frequency and sensitive to interference, between the processor and internal devices and vice versa. Its successful implementation is
therefore a key factor for the performance and reliability of the entire computer.It is composed of a printed circuit on which are welded a series of
integrated circuits, and Socket connectors; integrated the most important are the chipset that does most of the work interface between the main
components and the expansion bus, the Socket for the processor and the connectors required for assembly of the other components of the PC. The
current structure of the system boards of the computer is the result of technological trend that has led to define a system architecture valid, in
principle, for all the systems of personal computers or class of power comparable.
HARD DRIVE
A hard drive or fixed disk consists basically of one or more platters in rapid rotation, made of aluminum or glass, coated with ferromagnetic material
and by two heads for each disk device is a mass storage that uses one or more magnetic disks for the 'data storage. The inductive heads are
fundamental components of the hard disk and used for reading and writing on the disc surface, the data processed by a computer. The hard disk is
one of the types of memory devices of mass currently the most widely used. It is in fact present in most computers and in other electronic devices.
The hard disk has a serious competitor for a short time, the solid-state drive, which is likely in the future to replace it.
THE GRAPHICS CARD
The graphics card has the purpose of generating an electrical signal in output that can be then sent in input to video to be translated by the latter
into an optical signal and visually shown to the user. A typical video card contains an integrated graph that manages a certain amount of RAM. The
operation of a video card is very simple. Depending on the type of computer device that can be more or less powerful: the first models of video card
could only display text, then, there have been video card capable of displaying graphical output and, more recently, three-dimensional textured
models in motion and in real time. These types of cards shall also prepare and edit the image in its internal memory, and the cards can show 2D 3D
only with the help of the CPU that must run alone all the necessary calculations.
MEMORY
The main memory (also called memory) lets you temporarily store data during program execution. In memory are handled information. It is an
essential part and one of the keys to the success of your computer with the ability to store, in modern electronic systems, large amounts of data
well beyond human capabilities. In it are stored archive data and user program instructions usable by the user. A memory can be regarded
theoretically as a finite sequence of cells where each cell contains a finite sequence of bits, normally managed in groups of eight such bytes.
Therefore the physical space of the memory can be thought of as a sequence of positions, each containing one byte. Each location is identified by a
specific memory address, normally expressed by a positive integer. The memory corresponds to what is called RAM (Random Access Memory ie
random access memory) and ROM (Read Only Memory that is, read-only memory).
