Detailed explanation-1: -Option d-Faster processing speed is not an advantage of the computer network, hence It is a correct answer.
Detailed explanation-2: -Disadvantages of Network Model : The design or the structure of this model is not user-friendly. This model does not have any scope of automated query optimization. This model fails in achieving structural independence even though the network database model is capable of achieving data independence.
Detailed explanation-3: -The network database model allows records from more than one table to be associated with a single owner record of another table. This provides a definite advantage over the relational counterpart when querying results from multiple foreign-key tables associated with one primary-key table.
Detailed explanation-4: -Network models represent complex data relationships better than the hierarchical models. It handles so many relationship types. Data access is more flexible than hierarchical models. Improved database performance. It includes Data Definition Language (DDL) and Data Manipulation Language (DML) commands. 03-Jul-2021
