Advanced Networking Technologies | General Questions & Answers
Q. What is a Network?
Answer: Network is defined as a set of devices connected to each other using a physical transmission medium.
Q. What is Network Topology?
Answer: Network topology is a physical layout of the computer network and it defines how the computers, devices, cables, etc. are connected to each other.
Q. What are Routers?
Answer: The router is a network device that connects two or more network segments. It is used to transfer information from the source to the destination.
Q. Explain TCP/IP Model?
Answer: The most widely used and available protocol is TCP/IP i.e. Transmission Control Protocol and Internet Protocol. TCP/IP specifies how data should be packaged, transmitted and routed in their end to end data communication.
Q. What is a Firewall?
Answer: Firewall is a network security system that is used to protect computer networks from unauthorized access.
Q. Define Static IP and Dynamic IP?
Answer: When a device or computer is assigned a specified IP address then it is named as Static IP. It is assigned by the Internet Service Provider as a permanent address.
Dynamic IP is the temporary IP address assigned by the network to a computing device. Dynamic IP is automatically assigned by the server to the network device.
Q. What is RFID Tags?
Answer: RFID is an automatic identification method relying on storing and remotely retrieving data using devices called RFID Tags.
Q. What is Bluetooth?
Answer: Bluetooth is a high-speed, low-power microwave wireless link technology, designed to connect phones, laptops and other portable equipment together.
Q. What is Network management?
Answer: Network management is the process of controlling a complex data network to maximize its efficiency and productivity.
Q. What do you mean by network topology?
Answer: Network topology specifies the layout of a computer network. It shows how devices and cables are connected to each other. The types of topologies are:
Bus Topology: Bus topology is a network topology in which all the nodes are connected to a single cable known as a central cable or bus.
Star Topology: Star topology is a network topology in which all the nodes are connected to a single device known as a central device.
Ring topology: Ring topology is a network topology in which nodes are exactly connected to two or more nodes and thus, forming a single continuous path for the transmission.
Mesh topology: Mesh topology is a network topology in which all the nodes are individually connected to other nodes.
Q. What is LAN, WAN, MAN?
Answer:
LAN (Local Area Network): It is used for a small geographical location like office, hospital, school, etc.
WAN (Wide Area Network): It is used over a wide geographical location that may range to connect cities and countries.
MAN (Metropolitan Area Network): It is used to connect the devices which span to large cities like metropolitan cities over a wide geographical area.
Answer: Simplifying communications between devices and the internet.
Operates in licensed exempt ISM band at 2.4ghz
Omni directional, no requiring line of sight
Bluetooth offers data speeds of up to 1 Mbps up to 10 meters
Bluetooth supports a LAN-like mode where multiple devices can interact with each other.
Q. What is Cloud Computing?
Answer: Cloud Computing is a technique for delivering services within which resources are retrieved from the net through web based tools and applications. Or
Cloud Computing is a network of remote servers hosted on the internet for storing and retrieving data.
