COMPUTER NETWORKING

Detailed explanation-1: -Viruses and malware can be a major disadvantage of computer network. If left unchecked, these malicious programs can spread quickly across the entire system, leading to data loss, interference in services, and costly repairs.

Detailed explanation-2: -Viruses can delete programs, manipulate keyboards, allow access to sensitive information, or flood a network with traffic, making it impossible to do anything online.

Detailed explanation-3: -One drawback of linear network coding is the increase in overhead of encoding and decoding data. As will be seen in later sections, computational overhead makes some network coded cloud storage systems inefficient in comparison to more widely known redundancy configurations.
