6.Synchronous DRAM, a type of DIMM memory that synchronizes itself with the computer’s system clock to provide a synchronization between the memory and the computer processor. 7. The primary benefit of DDR3 is the ability to transfer I/O data at eight times the speed of the memory cells it contains. DDR3 standard allows for chip capacities of 512 megabits to 8 gigabits, effectively enabling a maximum memory module size of 16 gigabytes. 8.
(Choose two answers.) a. Used for short-term memory b. Used for long-term memory c. Used to process data d. Connects to the CPU over a bus using a cable e. Is installed onto the motherboard 5. This chapter describes the concepts behind how a CPU reads the contents from RAM.
Which of the following answers best describes how a hard disk drive physically writes a binary 0 or 1?C. changing the disk’s surface 12. Which of the following answers are true about an internal hard disk drive (HDD) as it is normally used inside a personal computer (choose 2) B. used for long-term memory, D. connects to the CPU over a bus using a cable
The purpose of a wireless router is to send and receive data across a network wirelessly. Many routers have updated tables within the router to learn where which computers are in a network. This will speed up the transfer of the data packets since the packet is only going to the designated computer. Wireless routers also have ports on the back which accepts an Ethernet cable from a high speed modem so internet connectivity can be shared. Wireless routers are connected to a network wirelessly and/or wired.
Both management’s executive and senior have work stations with Apple iMac computers that vary in size of monitors and gigahertz and hard drive capability. Operating systems are MAC OS X and Windows XP. [ (UOP, 2011) ] “This system is there to help improve the communication and collaboration between senior management, employees, doctors, nurses, and patients”. [ (UOP, 2011) ] Very important management uses the network to maintain the accounting and finance, human resource, customer relationship, and knowledge management. The Radiology network is connected with the Ethernet and 1000 Base F single mode fiber.
Aims and context (Put aims of study & background history): The aim of the study was to answer the question to what extent (how much) might another species be able to use human language? One way to test this was to teach a form of human language to a non-human animal. Gardner & Gardner aimed to investigate if they could teach a chimpanzee (considered to be a most intelligent and sociable animal) to communicate using a human language, specifically that of American Sign Language. Context - Language makes us unique as an animal, Chomsky (1965) believes language is unique to humans, other species can’t acquire language, humans have a language acquisition device, animals don’t. Early attempts to teach chimps to talk were useless, a chimp’s vocal apparatus is unsuited to making speech sounds, however the Gardners felt that chimps can use a non-spoken language like ASL, this language is used by the deaf in America.
Unit 7 Assignment 1: Video Summary 5 Explain BIOS: Basic Input/ Output System * BIOS tells the hardware how to operate with the computer’s Operating System * BIOS is built into the motherboard and is standard on all computers * BIOS can be used to tune the computer’s hardware * A specialized key stroke is used to enter into BIOS before the system fully boots up * BIOS can only be navigated using key strokes (mouse will not work) * The first Tab shows the different types of internal hardware connections your computer has, IDE and SATA, along with what is connected to them (i.e. DVD Rom drive, hard disk) * Under Advanced Tab, CPU configurations can be changed if options are available (i.e. overclocking) * Under Power Tab, outputs are shown for power outputs of hardware devices (i.e. voltages used and cooling fan speeds, and temperatures of hardware * Under Boot Tab, you are allowed to set up the sequence in which the computer will boot up from (i.e. hard drive, CDROM, or Removable) * Under Exit Tab, You are given the option on how to exit from BIOS with or without saving changes Explain POST: Power On Self Test * POST is a test to determine a computer’s hardware is not faulty before it boots * When a problem occurs BIOS will register an error * A sound messaging speaking is located on the motherboard that will issue a series of beeps when a problem is found.
Stafone Jefferson Unit4Assignment1 Motherboard specifically refers to a PCB with expansion capability - the board is the "mother" of all components attached to it, which often include sound cards, video cards, network cards, hard drives or other forms of persistent storage, TV tuner cards, cards providing extra USB or Firewire slots, and a variety of other custom components. 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. Motherboard Most important consideration * Motherboard CPU Size and Shape * Determined by form factor ATX Form Factor * Replaced older AT form factor * Smaller * Better Organization * Easier to work on * Support for variety of I/O Devices Soft Power Switch * Front of Computer * Does not immediately cut power * Allows Normal OS shutdown process Power Switch * Back of computer * Immediately kills all power Wake on LAN * Configured in CMOS * Keyboard * Network Activity
This video explains the purpose of the ports and devices. * Serial Port: Transmits data 1 bit at a time. A serial port is a general-purpose interface that can be used for almost any type of device, including modems, mice, and old printers * Parallel Port: Transmits data 8 bit at a time. A parallel interface for connecting an external device such as a printer. the parallel port uses a 25-pin connector (type DB-25) and is used to connect printers, * Gaming Port: 15 pins, * Mouse and
CIS 105 Week 3 DQS CIS 105 DQ 1 There are a variety of computers available, from the smallest computer in a domestic device to the supercomputers used in industry. Despite the different uses for computers, they all have basics elements in common—each computer system involves hardware, software, data, and users. Think about the role of each component of your home or work computer: How do the components of your computer system interact within the system? What improvements or additions to your system do you think would benefit you or make the system more user-friendly?
