Essentials of Data Communication and Networks

Description

Network-centric information technology is a topic that is covered in detail in Data Communication and Computer Networks. The detailed framework of the core ideas is given to the reader. Different types of personal computers, an operating system, a network adapter, adapter drivers, cabling, and the protocols used to connect these components are all networking components. Similar to voice communication, there are numerous data communication techniques, including modulation, multiplexing, and analog-to-digital conversion. The smallest network a user can access directly is a personal area network (PAN). Devices with Bluetooth or infrared capabilities could fall under this category. The connectivity range of PAN is up to 10 meters. PAN may include wireless TV remotes, Bluetooth-enabled headphones, printers, and computer keyboards and mice. A local area network is often used to describe a computer network spread throughout a building and run by a single administrative system (LAN). LAN typically spans a company's headquarters, classrooms, colleges, and universities. There could be as few as two or as many as 16 million systems linked to a LAN. Data transmission and computer networks are very intriguing subjects, so much effort has been put into creating objective questions so that the student may benefit from the exercises in the best way to gauge his or her comprehension of the concepts.
