Assignment 1: Computer Archtecture Intro to Info Technology – CIS 106031VA016-1144-001 Professor John Murnane May 4‚ 2014 Von Neumann Architecture Von Neumann architecture is a stored program architecture with no differentiation between data and instruction memory. Both the data and instruction reside on a single chip. The concept of no differentiation between data and instruction memory is accurate‚ but existing on one chip has nothing to do with it. Most computer memories

occur due to the over-speed of the vehicles‚ mostly by the youngsters. To prevent these road accidents I’m proposing a system that could reduce rate of accidents drastically. The main advantage of this system is that the vehicle’s speed will controlled as described by respective department using Bluetooth. This is more useful at highways where the speed of every vehicle is found very high. Introduction: My proposal is that every vehicle will to be installed with a speed control device confined

Redundant Array of Independent Disks or Redundant Array of Inexpensive Disks. 2. When would we use RAID? RAID can be used when there’s a lot of important data that we are constantly changing and need to back up often. 3. Define the following types of RAID: a. RAID 0- Has Stripped Blocks and has no Redundancy. Has to have two disks b. RAID 1- Is a mirrored blocks and is the best performance of the four because it isn’t striped and has no parity. It also needs two drives. c. RAID 5- It has striped

Random Access Memory (RAM) RAM is a location within the computer system which is responsible for stacking away data on a temporary basis‚ so that it can be promptly accessed by the processor. The information stored in RAM is typically loaded from the computer’s hard disk‚ and includes data related to the operating system and certain applications. When the system is switched off‚ RAM loses all the stored information. The data remains stored and can be retained only when the system is running.

Mac‚ Linux‚ and Windows Servers Comparison Apple offers only a few options for server hardware‚ and only one option for server software. The hardware I looked at was the Mac Mini with OS X Server. With a relatively low starting price point of $999 that includes the software‚ Apple surprisingly wins the cost category‚ at least when looking at up front costs (Mac Mini With OS X Server Overview‚ n.d.). The Mac Mini hardware includes 2TB of storage space‚ 4GB of Memory‚ and is backed by Apple’s
