IT and Network Concepts Quiz

What is a network?

• A software that supports communicating data electronically

• A computer that is designed to request information from a server

• Two or more computers that are connected with one another for the purpose of communicating data electronically

• Cables that connect multiple computers together

Which of the following is a major benefit of adopting an IT infrastructure?

• be able to develop customized services to meet the requirements of individual applications

• be able to diversify the IT solution innovations

• be able to deliver the customized information to individual customers more efficiently

• be able to provide standardized service offerings and leverages a uniform delivery mechanism across multiple applications

What includes two or more private, public, or community clouds, but each cloud remains separate and is only linked by technology that enables data and application portability?

• Community cloud

• Private cloud

• Hybrid cloud

• Utility computing

Which of the follow is not the part of IT infrastructure

• Middleware

• Human resource

• Business Application

• Operating systems

• Network communications

What is Software as a Service (SaaS)?

• public cloud providers deliver applications over the internet through the browser

• public cloud providers offer storage and compute services on a pay-per-use basis

• public cloud providers provide the accessibility of business-critical data in a timely, secure, and affordable manner.

• public cloud providers provide sets of services and workflows that specifically target developers

• False

What is a client?

• Enables the transmission of data over public or private networks

• A communications, data exchange, and resource-sharing system created by linking two or more computers and establishing standards, or protocols, so that they can work together

• A computer that is designed to request information from other computers on the network

• Any network without a central file server and in which all computers in the network have access to the public files located on all other workstations

• True

• False

What is packet-switching?

• Occurs when the sending computer divides a message into a number of efficiently sized units called packets, each of which contains the address of the destination computer

• Refers to the geometric arrangement of the actual physical organization of the computers and other network devices in a network

• An intelligent connecting device that examines each packet of data it receives and then decides which way to send it onward toward its destination

• A model for applications in which the bulk of the back-end processing, such as performing a physical search of a database, takes place on a server, while the front-end processing, which involves communicating with the users, is handled by the clients

What is network topology?

• Occurs when the sending computer divides a message into a number of efficiently sized units called packets, each of which contains the address of the destination computer

• An intelligent connecting device that examines each packet of data it receives and then decides which way to send it onward toward its destination

• A model for applications in which the bulk of the back-end processing, such as performing a physical search of a database, takes place on a server, while the front-end processing, which involves communicating with the users, is handled by the clients

• Refers to the geometric arrangement of the actual physical organization of the computers and other network devices in a network
