2004-2005 Academic Year, Spring Semester Bilkent University - Faculty of Art, Design and Architecture Department of Communication and Design CS 153 Introduction to Computing I Lesson 3

Answers to Homework 1 1. Name 2 Peer to Peer networks. 1. Edonkey 2. Icq 5. Send a e-mail to me with the topic “Homework Question 5” and your name and number at the body, of which I cannot see who you send the mail to. (so my outlook will say Undisclosed recipients at to: field of the mail I receive.) 1. You should use Bcc: field when sending the e-mail and leave To: and CC: fields empty. 6. Search and find five FTP Client Programs and a FTP Server program using your favorite web search engine. (Do not just take the list from your friends.) 1. BulletProof FTP Client, FTP Voyager 11.2, AutoFTP Professional 4.4, FTP Navigator 7.4, BitKinex 2.4, Robo-FTP, AceFTP, AbleFTP, CuteFTP, CyDFTP... 2. Serv-U 7. Define the cycle of processing and state which computer hardware is used in the cycle of processing. Which stages do we store data, if we don’t store the data what happens? 1. Input  processing  output. We store data in every stage and every intermediate stage. Because if we don’t store the data, it’s lost. For input: HDD, FDD, System memory; for processing: Registers and Cache at processor; for output: system memory, memory of our video card, HDD, FDD... 8. Give two reasons why today we start to have 64 bit processors(i.e. Athlon 64, Itanium). Wasn’t 32 bit processor (i.e. Pentium 4, Athlon XP) enough for todays computing needs? 1. Most important reason is as 2^32 = 4 billion, memory of a computer is limited to 4GBs, and this is limiting to have more memory. Another reason, with 64 bits we can move data faster, 64 bits a time instead of 32... 9. What is a DVD and name and list the capacities of a DVD. 1. Digital Versatile Disk, Digital Video Disk. Single layer single side: ~ 4.7 GB, double layer single side ~ 8.5GB, double layer dual side: ~ 17 GB<
