Frequently Asked Questions
Q1: What is computer network and how are they classified?
A1: Computer network is a system of interconnected computers and computerized peripherals like printers. This interconnection among the computers makes it possible for the information to share among them. Information will be shared through this medium and thus the data is communicated. The communication happens either by wired or wireless media. These networks are classified based on the following factors
Q2: What are the network applications? The sims online 2019.
A2: To form a network, Computer systems and peripherals are connected with each other. Some of the advantages or application are,
Tipard mac video converter ultimate 9 1 20 crack download. Q3: What is Personal Area Network?
A3: Smallest network that is very personal to user is called A Personal Area Network (PAN) which may include Bluetooth enabled devices or infra-red enabled devices. This network has approximately 10 meters of connectivity range. It may include wireless mouse, keyboard, printers, bluetooth etc.
Q4: What is ethernet?
A4: Invented by Bob Metcalfe and D R Boggs in 1970, it is deployed Local Area Network (LAN) technology which shared media. Network using shared media has high chances of data collision. Using collision detection technology or carrier sens multi access, ethernet detects collision. All the hosts roll back on the occurrence of collision in Ethernet. Later, wait for some amount of time and re transmit the data. It is equipped with 48-bits MAC (a network interface card) addressing other Ethernet devices to identify and communicate with remote devices in Ethernet. Traditional Ethernet utilizes 10BASE-T specifications. The specification are as follows,
