  1. 1. Cisco Discovery - DHomesb Module 1 - V.4 in english.Q.1 Which computer component is considered the nerve center of the computer system and isresponsible for processing all of the data within the machine ? RAM CPU video card sound card operating systemQ.2 What are two advantages of purchasing a preassembled computer ? (Choose two.) usually a lower cost exact components may be specified extended waiting period for assembly adequate for performing most general applications suited for customers with special needsQ.3 A user plans to run multiple applications simultaneously on a computer. Which computercomponent is essential to accomplish this ? RAM NIC video card sound card storage deviceQ.4 Which adapter card enables a computer system to exchange information with other systemson a local network ? modem card controller card
  2. 2. video card sound card network interface cardQ.5 What is the main storage drive used by servers, desktops, and laptops ? tape drive hard drive optical drive (DVD) floppy disk driveQ.6 Which component is designed to remove high-voltage spikes and surges from a power lineso that they do not damage a computer system ? CPU surge suppressor motherboard hard driveQ.7 What are two examples of output peripheral devices ? (Choose two.) printer speakers flash drive external DVD external modemQ.8 What two functions does a UPS provide that a surge protector does not ? (Choose two.) protects the computer from voltage surges provides backup power from an internal battery protects the computer from sudden voltage spikes gives the user time to phone the electrical company
  3. 3. gives the user time to safely shut down the computer if the power fails provides backup power through a generator provided by the wall outletQ.9 What is a word processor ? It is a physical computer component. It is a program designed to perform a specific function. It is a program that controls the computer resources. It is a functional part of an operating system.Q.10 What is the purpose of the ASCII code ? translates bits into bytes interprets graphics digitally translates digital computer language into binary language represents letters, characters, and numbers with bitsQ.11 Why do servers often contain duplicate or redundant parts ? Servers require more power and thus require more components. Servers should be accessible at all times. Servers can be designed as standalone towers or rack mounted. Servers are required by networking standards to have duplicate parts.Q.12 What are two benefits of hooking up a laptop to a docking station ? (Choose two.) Mobility is increased. An external monitor can be used. Alternate connectivity options may be available. The keyboard can be changed to a QWERTY-style keyboard. More wireless security options are available.
  4. 4. Q.13 Applications can be grouped into general use software or industry specific software. Whatare two examples of industry specific software ? (Choose two.) CAD presentation spreadsheet word processing medical practice management contacts/scheduling managementQ.14 Which three terms describe different types of computers ? (Choose three.) operating system network laptop desktop Windows mainframeQ.15 How is a server different from a workstation computer ? The server works as a standalone computer. The server provides services to clients. The workstation has fewer applications installed. The workstation has more users who attach to it.Q.16 How many values are possible using a single binary digit ? 1 2 4 8 9
  5. 5. 16Q.17 What measurement is commonly associated with computer processing speed ? bits pixels hertz bytesQ.18 What can be used to prevent electrostatic discharge (ESD) ? dry and non humid conditions carpeted floor grounding strap uncluttered work spaceQ.19 If a peripheral device is not functioning, what are three things you should do to solve theproblem ? (Choose three.) Use the testing functionality on the peripheral itself, if available. Verify that all cables are connected properly. Disconnect all cables connected to the computer except those connected to the peripheral. Ensure that the peripheral is powered on. Disconnect the peripheral and verify that the computer is operating normally. Reload the computer operating system.Q.20 Which two steps should be performed when installing a peripheral device ? (Choose two.) Download and install the most current driver. Connect the peripheral using any cable and any available port on the computer. Connect the peripheral using an appropriate cable or wireless connection. Test the peripheral on another machine before installing it on the one where it will be used. Check the computer documentation to see if the peripheral vendor is compatible with the PC
  6. 6. vendor.Q.21 In newer operating systems, how are system resources assigned by default whencomponents are installed ? manually assigned by the operating system manually assigned by the administrator statically assigned by the component to a preset resource dynamically assigned between the component and the operating system
