  • In This Video We Are Going to See How a Personal Computer Hardware Is Organised the PC Was Designed with an Open Architecture
    In this video we are going to see how a personal computer hardware is organised The PC was designed with an open architecture. This means that it uses standard modular components. We can add, replace, update or swap them easily and the computer will identify and handle the new devices automatically. The main component of a computer system is the motherboard or main board. It is a printed circuit board (PCB) that holds the main components of the computer and the electronics needed to communicate between them and to expand the system. We could say that it is the central nervous system of the computer. A motherboard provides the electrical connections by which the other components of the system communicate. Unlike a backplane, it also contains the central processing unit and hosts other subsystems and devices The form factor is the specification of a motherboard – the dimensions, power supply type, location of mounting holes, number of ports on the back panel, etc. In the IBM PC compatible industry, standard form factors ensure that parts are interchangeable across competing vendors and generations of technology, while in enterprise computing, form factors ensure that server modules fit into existing rack mount systems. Traditionally, the most significant specification is for that of the motherboard, which generally dictates the overall size of the case. The most used form factor for IBM PC compatible motherboards is ATX (Advanced Technology Extended) and its derivatives. For small form factor mainboards mini ITX is the de facto standard. A power supply unit (PSU) converts mains AC to low- voltage regulated DC power for the internal components of a computer.

  • Fractal Design Define R4 Offers Minimalistic and Stunning Scandina- Vian Design Fused with Maximum Sound Reduction, Configurability and Functionality
    Product Sheet Define R4 As part of the Define series of computer cases, the Fractal Design Define R4 offers minimalistic and stunning Scandina- vian design fused with maximum sound reduction, configurability and functionality. The Define R4 side and front door panels are fitted with dense, sound-absorbing material making it a benchmark for noise reduction. Moreover, the Define R4 accommodates up to 8 HDDs, all modern graphics card sizes, and multiple ventilation options - including two standard Silent Series R2 hydraulic bearing fans - to keep internal components at optimal temperatures. For ultimate functionality, the Define R4 features a front interface with USB 3.0 and an integrated three-speed fan controller behind the front panel door. Key features • High density noise-reducing material for an optimal silent case **To achieve a high level of noise reduction, material with mass should be incorporated which is what we strive to achieve with the dense bitumen used on the side panels • Patent pending ModuVent™ design allowing the user to choose between optimal silence or maximum airflow • Top HDD cage (5 trays total) can be rotated 90 degrees or removed for additional airflow or to accommodate long graphic cards up to 430mm in length • Three-speed fan controller is strategically integrated in the front panel and supports up to 3 fans • Two Silent Series R2 fans included, featuring hydraulic bearings contributing to a longer life expectancy – Silent Series R2 retail fans will now come standard in all cases • Wider case body that allows

  • Test-Drive Form That Follows Will Give You a Written Record to Reference at Your Own Pace in Your Own Home
    56 Would You Buy a Car Without Test-Driving It? realize it isn’t such a big deal, and then continue learning more about the computer before you make your investment. It’s empowering to know that this is nothing more than a research expedition. No obligation, no financial outlay, no decision making. If you don’t want to go back, there is always the option of mail order or purchasing from the store by phone so you never have to reenter the place. And remember, if the salesperson you are dealing with really doesn’t appeal to you, give him the brushoff, let him get out of sight, smile sweetly at another salesperson, and watch her come running. Initially the computer store can sometimes add to any confusion you might have, especially after you get home and try to remember all you saw. The Test-Drive Form that follows will give you a written record to reference at your own pace in your own home. Copy these pages to bring with you to the store. If it’s easier, rip the pages out to make the copies. Test-Drive form 1. Store: Salesperson: Note the address and phone number of the store and the name of the salesperson you spoke with. 2. Brand & Model of Computer: Include any numbers that follow the brand name—this will indicate the model. For example: Dell Dimension 966. 3. Cost: Note the basic cost and any additional costs. For example: $499 plus $50 for RAM upgrade = $549. sYsTeM iNforMaTioN 4. Computer Case: h Standard h Tower Is the computer case a standard model or a tower model that will go on the floor?

  • Chapter 1 PC Architecture
    Chapter PC Architecture THE FOLLOWING OBJECTIVES ARE COVERED IN THIS CHAPTER: 1 1.1 Identify the names, purpose, and characteristics, of system modules. Recognize these modules by sight or definition. 1.5 Identify the names, purposes, and performance characteristics, of standardized/common peripheral ports, associated cabling, and their connectors. Recognize ports, cabling, and connectors, by sight. COPYRIGHTED MATERIAL A personal computer (PC) is a computing device made up of many distinct electronic components that all function together in order to accomplish some useful task (such as adding up the numbers in a spreadsheet or helping you write a letter). By this definition, note that we’re describing a computer as having many distinct parts that work together. Most computers today are modular. That is, they have components that can be removed and replaced with a component of similar function in order to improve performance. Each component has a very specific function. In this chapter, you will learn about the components that make up a typical PC, what their function is, and how they work together inside the PC. Unless specifically mentioned otherwise, throughout this book the terms PC and computer can be used interchangeably. The components in most computers include: The case The power supply The motherboard The processor /CPU Memory Storage devices The adapter cards Display devices Ports and cables As you read this chapter, please keep in mind that many of these parts will be covered in more detail in later chapters. Figure 1.1 shows an example of a typical PC and illustrates how some of these parts fit together.
