Computer Networking

It is a router.

WANs are either point-to-point, involving a direct connection between two sites, or operate across packet-switched networks, in which data is transmitted in packets over shared circuits. Point-to-point WAN service may involve either analog dial-up lines, in which a modem is used to connect the computer to the telephone line, or dedicated leased digital telephone lines, also known as "private lines." Analog lines, which may be either part of a public-switched telephone network or leased lines, are suitable for batch data transmissions, such as nonurgent order entry and point-of-sale transactions. Dedicated digital phone lines permit uninterrupted, secure data transmission at fixed costs.

Point-to-point WAN service providers include both local telephone companies and long distance carriers. Packet-switched network services are typically chosen by organizations which have low volumes of data or numerous sites, for which multiple dedicated lines would be too expensive.

Depending on the service, WANs can be used for almost any data sharing purpose for which LANs can be used. Slower transmission speeds, however, may make some applications less practical for WANs. The most basic uses of WANs are for electronic mail and file transfer, but WANs can also permit users at remote sites to access and enter data on a central site's database, such as instantaneously updating accounting records. New types of network-based software that facilitate productivity and production tracking, such as groupware and work-flow automation software, can also be used over WANs. Using groupware, workers at dispersed locations can more easily collaborate on projects. WANs also give remote offices access to a central office's other data communications services, including the internet.

RADIUS has been officially assigned UDP ports 1812 for RADIUS Authentication and 1813 for RADIUS Accounting by the Internet Assigned Numbers Authority (IANA). However, prior to IANA allocation of ports 1812 and 1813, ports 1645 and 1646 (authentication and accounting, respectively) were used unofficially and became the default ports assigned by many RADIUS Client/Server implementations of the time. The tradition of using 1645 and 1646 for backwards compatibility continues to this day. For this reason many RADIUS Server implementations monitor both sets of UDP ports for RADIUS requests. Microsoft RADIUS servers default to 1812 and 1813 but Cisco devices default to the traditional 1645 and 1646 ports. Juniper Networks' RADIUS servers also default to 1645 and 1646.

tap the settings icon, then Wi-Fi, put it on and check if your network is listed (wait 30 sec it may take some time) if it is not listed, tap on "other" and typ the name of your network, the kind of security and the password (optional).

Organizations are all different; they have the choice of using multiple IP addresses for each client (1 address for each client, unique), or using the same IP address for all clients (via NAT proxy).

Usually the number of IP addresses is related to the number of public services that the organization will offer, such as DNS, e-mail, Web Services, FTP servers, and so on. If the organization is big enough it might use several IP addresses for each service instead of just 1 per service.

Whatever ports are required by the services, or daemons, that will listen for requests.

The IEEE standard that specifies the protocol for Carrier Sense Multiple Access (CSMA) is IEEE 802.3. This standard outlines the specifications for Ethernet networks, including the CSMA/CD (Collision Detection) protocol used in wired Ethernet systems. It defines how devices on a network should manage access to the shared communication medium to minimize collisions and ensure efficient data transmission.

A point-to-point radio network is the simplest form of wireless network. A point-topoint link is composed of two radios in direct communication with each other with dedicated bandwidth. Point-to-point links are ideally suited for high-performance, dedicated corporate j t connections, high-speed inter nest links or backup/back- applications. These links are generally quick to deploy but typically require RF planning and professional installation. Point-to-point radios are available in several licensed frequencies and in the unlicensed ISM (2.4 / 5.8 GHz) bands and can achieve distances of up to 50 miles. Point-to-point applications and users include cellular/PCS base station backhaul, last mile provisioning, private network interconnect, utilities, enterprise/corporations, disaster recovery and LAN/WAN/Internet connectivity.

Client-server networking is centralized - Resources and data security are controlled through the server. Scalability - Any or all elements can be replaced individually as needs increase. Flexibility - New technology can be easily integrated into system. Interoperability - All components (client/network/server) work together. Accessibility - Server can be accessed remotely and across multiple platforms. Speed - network will run far better as data and resources are handled by a dedicated machine. Also currently the user of the machine experiences poor performance when everyone accesses it's resources. Backup - as all data is stored centrally it is easy to backup. Support and management - as the server controls the majority of settings on the network etc the job of support is far easier as the main element of support is provided to the server and not individual machines. Global changes are easy to make from one location.

Client/server allows the installation of anti-virus on a dedicated server, this means that all stations that are connected to that server are protected against viruses. In peer to peer, each station has to be installed with the anti-virus. Because peer to peer allows the sharing of files it is possible that some files are infected and because anti-virus is not as effective on peer to peer, the virus would get in and disrupt the network.

yes. thougth the nic is a layer 1 device its mac address is used in datalink layer

veeeeeeeeeeeeery unlikely. most common connection between two pcs would be CAT5/Cat6 (commonly misconceived as Ethernet cable). deploying optic fibre would be unessesary but very fast. it isn't used between computers because of the cost implicated

100BaseT: Max. Speed is 1000 Mbps. and has 4 pairs of of Category 5e or higher. 10BaseT: Max. Speed is 10 Mbps.

WEP has been replaced by WPA.

The correct answer is switch.

Transmission media is a device which is used to transfer the data between one computer to another computer.There are two types of Transmission media:

1. Guided Media

2. Unguided Media
