Introduction to networks
What are some of the key advantages of a MPLS over a WAN?
(four of them) Cost saving, QOS enablement, Improved performance, Disaster recovery, and Future Proofing the network.
What are small groups of LAN's called?
A LAN party is a gathering of people with computers or compatible game consoles, between which they establish a local area network (LAN), primarily for the purpose of playing multiplayer video games.
What is a computer workgroup?
A workgroup is Microsoft's term for peer-to-peer local area network. Computers running Microsoft operating systems in the same work group may share files, printers, or Internet connection.
Define the following physical network topologies and the pros and cons of each.
Bus- is an arrangement in a local area network (LAN) in which each node (workstation or other device) is connected to a main cable or link called the bus. star- is a local area network (LAN) in which all nodes (workstations or other devices) are directly connected to a common central computer. ring- is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node - a ring. mesh- is a network topology in which each node relays data for the network. point-to-point- is a permanent link between two endpoints. Switched point-to-point topologies are the basic model of conventional telephony. point-to-multipoint- is a common network architecture for outdoor wireless networks to connect multiple locations to one single central location. hybrid- is a combination of different circuits, for example a combination of MPLS and Internet Circuit can be your hybrid network.
In what language does computers talk to each other?
Computers communicate through programming and coding.
What do the following servers do?
File server- is a computer attached to a network that has the primary purpose of providing a location for shared disk access. Mail servers- is a server that handles and delivers e-mail over a network, usually over the Internet. A mail server can receive emails from client computers and deliver them to other mail servers. Print servers - is a device that connects printers to client computers over a network. Web server - is a computer system that processes requests via HTTP, the basic network protocol used to distribute information on the World Wide Web. Fax Servers - is a system installed in a local area network (LAN) server that allows computer users whose computers are attached to the LAN to send and receive fax messages. Application server - is a server program in a computer in a distributed network that provides the business logic for an application program. Telephony servers - refers to an entity in a telephone network that carries out functions that are not directly related to the routing of messages through the network. Proxy server - also known as a "proxy" or "application-level gateway", is a computer that acts as a gateway between a local network (e.g., all the computers at one company or in one building) and a larger-scale network such as the Internet. Do servers need to have superior CPU's, hard drive space and memory? Depends on the amount of users you wish to have on the server, if you want nearly 25 people: 25 Concurrent Users CPU: Quad 2GHz+ CPU RAM: 4GB Minimum database space: 10GB
Where should servers be placed?
Most servers are placed and held in a room designated, known as "Server Room"
What does MLS stand for?
Multilayer switching
What is the basic purpose of a local area network (LAN) ?
Two of the primary uses of LAN are: Wifi and Ethernet technologies.
What are the three most common network components and what do they do?
Workstation - is a special computer designed for technical or scientific applications. Servers - is a powerful computer connected to your business network. Network servers have many functions and can form an important part of your computer network. Hosts- is a computer or other device connected to a computer network. A network host may offer information resources, services, and applications to users or other nodes on the network.
Two of the primary uses of LAN are: Wifi and Ethernet technologies.
a group or system of interconnected people or things. Each computer or device on the network is a node. Wired LANs are most likely based on ethernet technology. Newer standards such as ITU-T G.hn also provide a way to create a wiredLAN using existing wiring, such as coaxial cables, telephone lines, and power lines.
What is TCP/IP stand for and what does it connect?
because its most important protocols, the Transmission Control Protocol (TCP) and the Internet Protocol (IP) were the first networking protocols defined in this standard. Is the basic communication language or protocol of the Internet.
What is a peer to peer network?
computing or networking is a distributed application architecture that partitions tasks or work loads between peers. Peers are equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes.
How does a MPLS work?
informs us that "when MPLS was conceived, Label Lookup and Label Switching were faster than a RIB lookup because they could take place directly within the switched fabric and not the CPU.
What is a router?
is a networking device that forwards data packets between computer networks.
What is a client machine?
is a piece of computer hardware or software that accesses a service made available by a server.
What does a WAN stand for and what are they used for?
is a telecommunications network or computer network that extends over a large geographical distance.
What is a client server network?
model of computing is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients.
