What is the cable or communications technology that computers must access to communicate across a network?
The __________ is the cable or communications technology that computers must access to communicate across a network. Select one: a. Protocol b. Software c. Medium d. Connector
Design issues of layers in computer network?
design issues of layers are basically dealing with protocols and designing for efficiency.also differentiating between interfaces ,services and protocols is essential.in layered architecture function of each layer should be defined.
What are two components of network architecture?
-Programmed services and protocols that move the messages across the network -Technologies that support network communications
Which layer of the OSI reference model permits the devices on the network to hold ongoing communications across the network?
network session layer Session Layer (Layer 5) The session layer permits two parties to hold ongoing communications called a session across a network.
What computer network tool is used to test whether a particular host is reachable across an IP network?
Ping
What layers of the OSI model are implemented in hardware?
The physical and link layers (layers 1 and 2) are implemented in hardware. The remaining five layers use these two layers to communicate across a network, and are done by software.
What is the cable or communications technology that computers must access to communicate across a network?
The __________ is the cable or communications technology that computers must access to communicate across a network. Select one: a. Protocol b. Software c. Medium d. Connector
Devices which are works on osi model 7 layers?
Devices that operate across the OSI model's seven layers include routers, switches, and firewalls. Routers function primarily at Layer 3 (Network) by directing data packets between networks, while switches operate mainly at Layer 2 (Data Link) to facilitate communication within a local area network. Firewalls can work at multiple layers, inspecting traffic and enforcing security policies across Layer 3 and Layer 4 (Transport), and sometimes even higher layers. Additionally, gateways can operate at all layers, translating between different network protocols.
What nodes on a network to communicate with each other and access the network each node needs a?
Each node on a network needs a unique identifier, typically an IP address, to communicate with each other and access the network. Additionally, nodes may require network interface cards (NICs) to physically connect to the network and protocols, such as TCP/IP, to ensure proper data transmission. This combination allows nodes to send and receive data accurately and efficiently across the network.
What is network monetoring?
Network monitoring is the action of examining what's going across a network (what data is being transmitted). You monitor a network mainly for troubleshooting (network and upper layers, e.g. an application) and for carrying out flow analysis studies (e.g. to help find a bottleneck or correctly size future equipment.
Difference between computer network and distributed operating system?
On a computer network, operating systems communicate with each other. In a distributed operating system, a single OS is communicating with itself across multiple machines.
What network component request services across the network?
A client requests services across a network.
Select 3 ways to recognize that the network is working?
1) Data can be passed across the network. 2) Multiple devices are seen and accessible across the network. 3) The internet can be accessed across the network.
What 2 words make up internet?
The two words that make up "internet" are "interconnected" and "network." The term describes a global network of computers and devices that communicate with each other, allowing for the exchange of information and data across vast distances.
List 3 ways to prove network functionality?
Command line utilities, (PING, IPCONFIG, TRACE) Microsoft Network Connections Utility
Design issues of layers in computer network?
design issues of layers are basically dealing with protocols and designing for efficiency.also differentiating between interfaces ,services and protocols is essential.in layered architecture function of each layer should be defined.
What does a LAN driver do?
A LAN driver, or a network card driver enables the operating system to communicate with the network card and transmit and receive packets of information across the network or LAN. It provides a "bridge" between the operating system (software) and the network card (hardware). This kind of layering provides a scalable architecture, where a single operating system can work with many network cards and vice-versa.
