What is DSN in JDBC?

A data source name (DSN) is a data structure that contains the information about a specific database that an Open Database Connectivity ( ODBC ) driver needs in order to connect to it. A user DSN allows database access for a single user on a single computer, and a system DSN for any user of a particular computer.

Is a switch a node?

Modems, switches, hubs, bridges, servers, and printers are also nodes, as are other devices that connect over Wi-Fi or Ethernet.

How are nodes identified?

Each device on a network that has a unique logical or IP (Internet Protocol) address can also be termed as a node. These nodes are identified by their IP addresses. Some Data Link layer devices(switches, bridges, WLAN access points, etc.) do not have an IP address.

What is the difference between a station and a node?

A network station is access through a microcomputer, workstation, cellphone, or main frame computer. Once the user has access to the network station the node allows one or more stations to access the physical network. The node transfers information/data/requests from point to point inside of the physical network.

How nodes are linked in a network?

Nodes: A node is a connection point inside a network that can receive, send, create, or store data. Each node requires you to provide some form of identification to receive access, like an IP address. While a router sends information between networks, a switch sends information between nodes in a single network.

Which network is suitable for single person operation?

System Area Network is used for a local network. It offers high-speed connection in server-to-server and processor-to-processor applications. The computers connected on a SAN network operate as a single system at quite high speed.

What is a node CIW?

Nodes. Any entity on a network that can be managed, such as a system, repeater, router, gateway, switch or firewall. A computer or other addressable device attached to a network; a host.

What is a dotted quad CIW?

A dotted quad is a decimal representation of an IPv4 address that is human readable. It is represented in the form xxx.

What function does a proxy server perform?

Proxy servers act as a firewall and web filter, provide shared network connections, and cache data to speed up common requests. A good proxy server keeps users and the internal network protected from the bad stuff that lives out in the wild internet. Lastly, proxy servers can provide a high level of privacy.

What is a network quizlet?

A network consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, and allow electronic communications. Connects computers in small groups as well as peripherals such as printers to those computers.

What is the difference between a LAN and a WAN quizlet?

LAN refers to local area network and refers to a network of computers that allows them to communicate and exchange data in a specific geographic area while WAN refers to wireless network that allows the same interactions to take place over a large geographic area.

What is a router quizlet?

router. any computer or device which sends packets from one network to another, such as from your home network to the Internet. Most routers are small devices with Ethernet ports and wireless antennae, but any computer with two network interfaces (and the right software) can also serve as a router. switch.

What is main function of router?

A router receives and sends data on computer networks. Routers are sometimes confused with network hubs, modems, or network switches. However, routers can combine the functions of these components, and connect with these devices, to improve Internet access or help create business networks.

What are the two functions of a router?

Explanation: Routers connect multiple networks, determine the best path to send packets, and forward packets based on a destination IP address.
