Motherboard . CPU . RAM . Adapter Cards . Internal and External Drives . Internal and External Cables 5 55 The Motherboard . The motherboard provides the electrical connections between the computer components. Comes in different sizes called “form factors.” . All the other components of the computer connect to the motherboard directly or through a cable. Image: By skeeze. Source Pixabay.

Source Wikimedia. License: CC BY-7SA 3.0 The Power Supply . Power Supplies come in different form factors and should match the form factor of the case. Power supplies are rated in watts and should have a rating larger than the total required watts of all the computer components. 8 8 Image: By Danrock Source: Wikimedia License: CC BY-SA 3.0 8 The Power Supply Connectors . The Power Supply will have lots of extra connectors so you can add additional components to your computer at a later time.

Stand offs raise the motherboard so it doesn't touch the case. Image: By Petteri Aimonen Source Wikimedia License: CC BY-SA 3.0 10 10 The Parts of a Computer . CPU—Central Processing Unit or Processor . Executes logical instructions like math and sends out the result. The speed of the CPU and the amount of RAM are the two biggest factors that effect computer performance Image: By Eric Gaba Lsource: Wikimedia icense: CC BY-SA 3.0 11 1111 CPU Alignment . CPUs use sockets that connect electrically with metal pins. One corner of both the socket and CPU will be different to indicate it is Pin 1. Align Pin 1 on the CPU with Pin 1 on the socket Image: By Julianprescott2604juuly Source Wikimedia License CC BY-SA 3.0 12 1212 The Worst Assembly Mistake! . Watch out! The CPU is fastened to the motherboard with a lever that presses the CPU into it’s socket. If the CPU is crooked, pushing the lever will break the pins on the CPU and/or the socket. Image By shoprepp: Soucre maxpixel License: CC BY-SA 3.0 13 13 CPUs Generate Heat and Need to be Cooled . It’s important to keep a CPU cool. CPU typically have a large piece of metal called a heat sink and fan to keep them cool. Image: By Victorrocha Source Wikimedai License: CC BY-SA 3.0 1414 14 Thermal Compound (also called Thermal Paste or Grease) . A small amount of thermal compound is used to fill the microscopic gaps between the CPU and the heat sink so that the heat moves away from the CPU to the heat sink. 1515 15 Volatile Memory RAM . Comes in different varieties and sizes. Use the motherboard manufacturer website to choose compatible RAM . RAM is volatile. That means all data in RAM is lost when the power is turned off. Image: By Topory Source Wikimedia License: CC BY-SA 3.0 1616 16 Internal and External Drives: Non-volatile Storage . Your computer will need some form of non- volatile storage. Some combination of hard drives (HHD), solid state drives (SSD), flash memory, optical drives and/or floppy drives. Images (left to right): Source maxpixel ,by D-Kuru Source Wikimedia by Evan-Amos Source Wikimedia License: CC BY-SA 3.0 17 17 Internal and External Drives . Internal Drives (hard drives and SSDs) store the operating system and other files. External Drives (DVD, CD and floppy) are used to transfer files to and from the internal drives. External drives have been largely replaced by thumb drives. 1818 Ports and Cables . There are many cables on both the inside and outside of a computer. Every cable plugs into a matching receptacle or port. The cables carry data, electrical power or both. The different port types are designed to minimize the possibility of plugging in a cable in the wrong way. 1919 Internal Cables . Internal data cables connect directly to the motherboard . Internal power cables connect directly to the power supply 20 SATA Internal Power and Data Cables . Data and power connectors for newer hard drives and CD/DVD drives. The smaller 7 pin cable is for data and the larger 15 pin cable is for power.

Double-click the “This PC” icon. 2. Under Network Locations, double-click the drive that begins with your username and ends with the letter “H”. To access your H: drive via File Explorer: 1. Click the yellow folder at the bottom left corner of the screen. 2. Under Network Locations, double-click the drive that begins with your username and ends with the letter “H”. Accessing Shared Drives If shared drives have been added to your profile, they will be located under Network Locations. If you need access to a departmental or school shared drive, please submit a work order so it can be added to your profile or email [email protected]. Creating Shortcuts on the Desktop Do not save documents/items directly to the desktop. If you would like to place documents on the desktop for quick- access, save your master documents to your H: drive and place a shortcut to the document on the desktop. To create a shortcut on the desktop to a program or file do the following: 1. Right-click an open area on the desktop, Select New, and then click Shortcut. 2. Click Browse. 3.

  • High-Performance and Highly Reliable File System for the K Computer
    High-Performance and Highly Reliable File System for the K computer Kenichiro Sakai Shinji Sumimoto Motoyoshi Kurokawa RIKEN and Fujitsu have been developing the world’s fastest supercomputer, the K computer. In addition to over 80 000 compute nodes, the K computer has several tens of petabytes storage capacity and over one terabyte per second of I/O bandwidth. It is the largest and fastest storage system in the world. In order to take advantage of this huge storage system and achieve high scalability and high stability, we developed the Fujitsu Exabyte File System (FEFS), a clustered distributed file system. This paper outlines the K computer’s file system and introduces measures taken in FEFS to address key issues in a large-scale system. 1.

  • Python Style Guide
    CS 102: Python Style Guide This documents provides some standards that will help ensure you are writing good code in this course. Good coding standards allow students to clearly demonstrate their plan for a program, and they help avoid confusion and errors. Each coding assignment in this course will be assessed partly on the items below. Heading Comment at Top Each Python file you submit must have a comment at the top that includes your name, the date of the assignment, and the assignment number. Here is an example: # Kowshik Bhowmik # Assignment 1: Style Guide # 08/01/2020 Descriptive Names Variables, parameters, and functions must have descriptive names. While naming all your variables after your favorite fast food menu items or your favorite Pokemon is fun, it won’t make for an understandable program. A good variable or parameter name describes what the variable stores and its role in the program. A good function name describes what the function does. Variable names tend to be nouns while function names are often verbs. Variable and function names will use the python standard. Names will be lower case with multiple words separated by an underscore. Variables that will hold values that are not meant to change are named in all upper case (this has no effect per say, but it is a stylistic convention). For example: total = 10 sales_tax = 20 search() calculate_amount() CONSTATNT = 10 MY_CONSTANT = 20 Descriptive Comments Every function you write should have a comment before it briefly describing what the function does, what the parameters are (if any), what side effects it has (if any), and what it outputs (if anything).
