Computer Network : Basic (Test 2)

A computer network is a system in which multiple computers and devices are connected to share data, resources, and services. It allows communication between users through the internet, email, file sharing, and cloud-based platforms.
Computer network knowledge is important for exams because it is a core subject in many courses like BCA, B.Tech, Diploma, and competitive exams.This online test is launched by Teachexam to provide students with a reliable and effective platform to practice and improve their knowledge of computer networks. The test is designed to be user-friendly, informative, and aligned with current academic and competitive exam patterns, helping students achieve better results and build a strong technical foundation.
