Exam 24: Organizational Structures That Support Strategic Initiatives

Telecommunication systems enable the transmission of data over public or private networks.

Packet-switching occurs when the sending computer divides a message into a number of efficiently sized units of data called packets, each of which contains the address of the destination computer.

How many layers does the OSI model contain?

What is a telecommunications system?

Hypertext transfer protocol (HTTP) allows web browsers and servers to send and receive web pages.

Fiber optic (or optical fiber) refers to the technology associated with the transmission of information as light impulses along a glass wire or fiber.

Which of the following is not a network topology?

What refers to a type of cable composed of four (or more) copper wires twisted around each other within a plastic sheath?

What allows Web browsers and servers to send and receive Web pages?

Simple network management protocol (SNMP) allows networked nodes to be managed from a single point.

Which of the following is not a commonly used type of guided media?

What 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?

What refers to a type of cable composed of four copper wires twisted around each other within a plastic sheath?

What is a computer that is designed to request information from a server?

Explain topology and the different types found in networks.

A network operating system (NOS) is the operating system that runs a network, steering information between computers and managing security and users.

The application layer serves as the window for users and application processes to access network services.

Network transmission media refers to the various types of media used to carry the signal between computers.

What refers to the technology associated with the transmission of information as light impulses along a glass wire or fiber?

Twisted-pair cable can carry a wide range of frequencies with low signal loss. It consists of a metallic shield with a single wire placed along the center of a shield and isolated from the shield by an insulator.
