A) to secure their network
B) to define how data transmits across transmission media
C) as a service for transferring funds
D) to classify their network cable types in order to connect devices

Accepted Answer

Standards such as EDI (Electronic Data Interchange) are used by businesses to define how data transmits across transmission media, ensuring that all parties involved in a transaction can communicate with each other effectively and efficiently. This includes standardizing the format and content of electronic documents, such as purchase orders, invoices, and shipping documents, to streamline communication between different computer systems, applications, and networks. EDI standards serve as a common language for business transactions, helping companies reduce errors, improve data accuracy, and strengthen relationships with vendors, suppliers, and customers.

Question 10

COGNITIVE ASSESSMENT Your school computer library has a network that connects computers and devices within a few small rooms. What type of network does it likely use?
A) LAN
B) WAN
C) MAN
D) VAN

Accepted Answer

LAN (Local Area Network) is a type of network that connects devices within a small geographic area, typically within a single building or campus. Therefore, a school computer library network, which connects computers and devices within a few small rooms, is most likely to be a LAN. WAN (Wide Area Network) covers a large geographic area, MAN (Metropolitan Area Network) covers an area larger than a LAN but smaller than a WAN, and VAN (Value-Added Network) is a type of private network used by businesses to securely transmit data.

Question 11

COGNITIVE ASSESSMENT What is another term for servers that control access to the hardware, software, and other network resources?
A) client computers
B) node computers
C) receiver computers
D) host computers

Accepted Answer

Host computers are servers that control access to the hardware, software, and other network resources. Client computers refer to devices that request and use resources from the servers. Node computers and receiver computers are not commonly used terms in network technology.

Question 12

COGNITIVE ASSESSMENT What term describes the process in which two or more computers or devices transfer data, instructions, and information?
