-A network is two or more devices connected through links.
-There are two possible types of connections: point-to-point and multipoint.
-A point-to-point connection provides a dedicated link between two devices.
Explain the different types of topologies
-Star network… In star topology each device in the network is connected to a central device called hub. Unlike Mesh topology, star topology doesn't allow direct communication.
-Ring network… A number of repeaters are used for Ring topology with large number of nodes, because if someone wants to send some data to the last node in the ring topology
-Bus network… In bus topology there is a main cable and all the devices are connected to this main cable through drop lines. There is a device called tap that connects the drop
-tree topology… Tree topologies have a root node, and all other nodes are connected which form a hierarchy. So it is also known as hierarchical topology. This topology integrates
-Computer network… Ring Topology; Star Topology; Mesh Topology; Tree Topology; Hybrid Topology; How to select a Network Topology? Types of Networking Topologies.
-Mesh networking… Ring Topology; Star Topology; Mesh Topology; Tree Topology; Hybrid Topology; How to select a Network Topology? Types of Networking Topologies.
Different type of networks
-Computer network… Virtual Private Network (VPN). By extending a private network across the Internet, a VPN lets its users send and receive data.
-LAN… Using routers, LANs can connect to wide area networks (WANs, explained below) to rapidly and safely transfer data. 3. Wireless Local Area Network (WLAN).
-Wide area network… Wide area network, or WAN. In terms of purpose, many networks can be considered general purpose, which means they are used for everything from sending files etc.
-Metropolitan area network… MAN or Metropolitan area Network covers a larger area than that of a LAN and smaller area as compared to WAN. It connects two or more computers that are apart.
-Wireless LAN… WLAN (Wireless Local Area Network) helps you to link single or multiple devices using wireless communication within a limited area like home, school, or office
-Wireless network… A Wireless Local Area Network or WLAN is a network that is used to connect different devices without using wires etc.
-Storage area network… Storage Area Network is a type of network which allows consolidated, block-level data storage. It is mainly used to make storage last longer etc.
-Personal area network… PAN can be used for establishing communication among these personal devices for connecting to a digital network and the internet.
-Campus area network… A Metropolitan Area Network or MAN is consisting of a computer network across an entire city, college campus, or a small region. This type of network is large.
Explain your own understand about protocol and standards
A protocol defines a set of rules used by two or more parties to interact between themselves. A standard is a formalized protocol accepted by most of the parties that implement it.
explain layers in OSI model
Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Explain layers in tcp/ip model
Four layers of TCP/IP model are 1) Application Layer 2) Transport Layer 3) Internet Layer 4) Network Interface. ... It is also known as a network layer. Transport layer builds on the network layer in order to provide data transport from a process on a source system machine to a process on a destination system.
what are the peer to peer processing
In peer-to-peer (P2P) networking, a group of computers are linked together with equal permissions and responsibilities for processing data. Unlike traditional client-server networking, no devices in a P2P network are designated solely to serve or to receive data
Answer: Jim left the computer unattended while shopping for supplies to be used at the next crime scene.
Explanation: While transporting the evidence to a secure location (lab), he left the computer unattended in his car and goes shopping for supplies that will be used in his next crime scenes. This act will give the criminals or their accomplice the opportunity to break into his car and tamper with what ever evidence he might have left behind in his car.
The term "savanna" is often used to refer to open grassland with some tree cover, while "grassland" refers to a grassy ecosystem with little or no tree cover.
performance -processor speeds increases because the smaller the transistor, the faster it can operate. Additionally, the transistors become closer to each other which reduces the latency between them.
2.Complexity-for a given size the number of transistors doubles with the reduction in feature size
