2024 INTRODUCTION TO IT EXAM QUESTIONS AND ANSWERS

What does the acronym IPOS stand for? Input, process, output, storage. (IPOS) represent the different tasks of computers. Which of the following is/are true of the IPOS cycle Once words, numbers or images are entered, a computer processes the data into useable information that can then be accessed to answer questions or meet specific needs. Correct. This is a description of how a computer uses the IPOS cycle. Which of the following include only elements of a computer system? Select all that apply CPU, users, keyboard, and memory Monitor, print drivers, operating system, and mouse Which of the following is an accurate definition of a computer system? A computer system is a collection of hardware and software components that work together to meet the needs of the user. Which of the following is an accurate statement about the software in a computer system? Select all that apply. A computer system needs software to be able to communicate with users as well as other computers. Software must be part of the computer system in order for the system to be useful. The software in a computer system may be shared if the system is a part of a network. Correct. All three of these are accurate statements about the software in a computer system. Which of the following would NOT be considered hardware? Correct. A word processor is a software program to enter data and is not part of a computer's hardware. Teachers in the Lincoln County School District are complaining about the speed of the Internet in their classrooms. Marcus, the IT Coordinator, has a limited amount of money to spend to address the issue. Select the option below that uses hardware or software to help solve the problem. Marcus determines the school's routers that transmit information from the Internet across the district are slow and outdated, so he will use the money to replace them. Select the statement that best describes the difference between software and hardware. Computer software is developed by writing a program using programming language whereas computer hardware is the physical components such as memory modules and disk drives. Which answer most accurately describes the timeline of computer development? First, computers built and programmed by engineers. Next, limited use of computers by large organizations. Next, introduction of personal computers. Lastly, Graphical User Interface systems are introduced. Which statements about the history of computer development are correct? Select all that apply. The development of new hardware and software requires special training. The following are examples of Graphical User Interface systems: GPS systems, ATM machines, and tablets and smart phones. The capabilities and complexities of computers have grown substantially, but the ease of use has also made them user friendly. Correct. These three options accurately describe the history of computer development. How have computer users changed over the last 75 years? Almost anyone can be a computer user today whereas in the past only computer scientists and those with specialized training used computers. Which of the following would NOT require the use of a network? Loading a statistical program on your personal computer. Which of the following statements describes why network protocols are necessary Network protocols are necessary for computers to communicate with each other. Which of the following statements describe why businesses use networks? Select all that apply. Businesses use networks for data sharing. Businesses use networks to reduce costs. Businesses use networks for customer support. Which of the following statements is true of computer networks Computer networks allow individuals to share many types of resources. Which of the following describes local computers only? Is a computer that a person is physically at. Correct. Where a person and computer are located together makes a computer local. Which of the following is the best definition of a computer network? A computer network is a collection of computers and computer resources (e.g., printers, file servers) connected in such a way that the computers can communicate with each other and their resources. Correct. Computer networks include the physical computers as well as other hardware devices such as printers and software and networks allow all devices to communicate. What is the most common type of network connection in use today? Fiber optic and UTP Which of the following type of transmission is paired correctly with the given media? fiber optic cable - light impulses Why would it be desirable to use a switch as opposed to a hub in a network? Because switches only transfer information to specific computers within a network and not all of the computers, the bandwidth used with a switch is less than that of a hub. Which of the following devices is used to connect one network to another network? router Which of the following communication system hardware devices is commonly used as a wireless access point? router Correct. Routers can be used as a wireless access point. Which of the following are characteristics of a packet-switched network? B. The choice of pathway is based on network availability and amount of message traffic. C. The route is established one branch at a time. How do a router and switch differ when handling a message? The router will purposefully drop messages if message traffic exceeds its capacity. Correct. A router has additional decision-making capabilities compared to a switch. In a client-server network, what is the role of the server? The role of the server is to take requests from the client and send back the requested information. How do virtual machines support a business computing ecosystem? A virtual machine (VM) is made available by software and permits a computer to run multiple OSs. In a business ecosystem, this allows for improved collaboration that is not restricted by platform software. Correct. A virtual machine allows a computer of one operating system to run other operating systems and applications specific to that alternative OS. Which of the following servers responds to HTTP requests on the Internet? web server Which of the following servers monitors requests, but doesn't send files in return? print server Which of the following servers can generate reports from client queries? database server Which of the following is NOT a characteristic of a bus network topology? Expensive compared to other topologies.
