Remote server is a very general category. It refers to any computer offering information to other computers. Most of the time, this refers to connecting to a server across the internet and this can be for the purpose of obtaining media, information, or really anything you might want to get from another computer. Large networks will often have a "remote DESKTOP server" as well, allowing login over the local network or across the internet to use the server, network and internet connection as if you were physically sitting in front of it. There are myriad other ways to describe a remote server,but this covers the basics.

How do you use ipconfig in windows 2000?
type "ipconfig" from a command prompt. (Start > Run > CMD) The basic command will display the essential IP address info for each network adapter: IP Address, Subnet, and Gateway There are several helpful switches. The most common: /all--displays complete IP configuration, such as DHCP servers, WINS Servers, DNS Servers /release--releases the lease on an IP Address assigned by DHCP /renew--requests an IP Address from the DHCP Server /?--returns a complete list of switches and syntax for this command
How many IP addresses does the router have?
A router may have multiple addresses depending on the number of interfaces to other networks. For a router to function effectively it must have at least 2 addresses, but some routers may have more.
They Should only have one.
What The most important different between hub and switch?
There really aren't five main differences between a hub and a switch; the main difference is that a signal is repeated across all ports in a hub, and only to the specific port in a switch.
What is public ip and private ip address?
The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets (local networks): 10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
Also, IP addresses in the range of 169.254.0.0 -169.254.255.255 are reserved for Automatic Private IP Addressing. These IP's should not be used on the Internet. I usually use 192.168.0.1, 192.168.0.2, etc. and a subnet mask of 255.255.255.0 when assigning static IP addresses to computers on a small Local Area Networks (LANs). If a DHCP server is also on the LAN it's scope (range of IP addresses that it can assign to computers on the LAN set to obtain their IP addresses automatically) should be adjusted so it does not interfere with locally assigned static IP addresses.
Why is TCP IP often called a protocol stack rather than a protocol suite?
The protocol stack used on the Internet is the Internet Protocol Suite. It is usually
called TCP/IP after two of its most prominent protocols, but there are other protocols
as well. The TCP/IP model is based on a fi ve-layer model for networking. From
bottom (the link) to top (the user application), these are the physical, data link, network,
transport, and application layers. Not all layers are completely defi ned by the
model, so these layers are "fi lled in" by external standards and protocols. The layers
have names but no numbers, and although sometimes people speak of "Layer 2" or
"Layer 3," these are not TCP/IP terms. Terms like these are actually from the OSI Reference
Model.
The TCP/IP stack is open, which means that there are no "secrets" as to how it
works. (There are "open systems" too, but with TCP/IP, the systems do not have to be
"open" and often are not.) Two compatible end-system applications can communicate
regardless of their underlying architectures, although the connections between layers
are not defi ned.
The term "protocol stack" is often used synonymously with "protocol suite" as an
implementation of a reference model. However, the term "protocol suite" properly
refers to a collection of all the protocols that can make up a layer in the reference
model. The Internet protocol suite is an example of the Internet or TCP/IP reference
model protocols, and a TCP/IP protocol stack implements one or more of
these protocols at each layer.
What type of topogy is required for use with a 100base-tx network?
star
network + guide to networks pg 105
Whoever answered that is a fool. Edition number? Yeah, guess you forgot. I have edition 5 here and that answer is not on page 105 or close to it either.
What are the uses of OSI layers?
The benefits of following the OSI model are as follows: * Any hardware that meets the OSI standard will be able to communicate with any other hardware that also meets the standard * Any software that meets the OSI standard will be able to communicate with any other hardware or software that also meets the standard * Consumers are given a wider choice since hardware/software from any manufacturer will work together * OSI is independent of country, it doesn't matter where the hardware/software is made * OSi is not dependent on the operating system used * The Protocols for OSI are defined at each stage * Any errors that occur are handled in each layer * The different layers can operate automatically Why is it important to have standards for communicating? * To enable devices to communicate together * To allow devices to be guaranteed as reliable * To allow purchasers to know the device will work How does the OSI model assist in the introduction and maintenance of standards? * It is an agreed standard that has world wide recognition * Use of the standard ensures compatibility * Purchasers recognize what the standard means and the guarantees that come with it
A gateway is a node (a router) on a computer network that serves as an access point to another network.
A Default Gateway is the node on the computer network that is chosen when the IP address does not belong to any other entities in the Routing Table. In homes, the gateway is usually the ISP-provided device that connects the user to the internet, such as a DSL or cable modem. In enterprises, however, the gateway is the node that routes the traffic from a workstation to another network segment. The default gateway is commonly used to be the node connecting the internal networks and the outside network (Internet). In such a situation, the gateway node could act as a proxy server and a firewall. The gateway is also associated with both a router, which uses headers and forwarding tables to determine where packets are sent, and a switch, which provides the actual path for the packet in and out of the gateway. In other words, it is an entry point and an exit point in a network.
Difference between peer to peer and client server?
In a peer to peer network, all nodes are the same. In a client-server network, conversely, the server node maintains control over other nodes.
At which OSI model layers do the application layer or upper layer protocols operate?
Application
Presentation
Session
What logical topology is used in a classroom?
Most classrooms rely on a star topology to connect their systems together.
Pingt stands for a name such as black people call white people cracker or something and ping just a discriminating name based on race
What is the limitation of length for category 5 UTP network cable?
For a single link the maximum is 100 meters.
Can you learn networking through online?
Set up your own network at home by getting the help from networking books or a website. For most people, this is the most useful method to learn networking with hands-on experience.
What is the difference between protocol and service interface in ISO-OSI 7 layer model?
Protocol is the special set of rules that end points in a telecommunication connection use when they communicate. In other words Protocol is an agreed-upon format for transmitting data between two devices. The protocol determines the following: * the type of error checking to be used * data compression method, if any * how the sending device will indicate that it has finished sending a message * how the receiving device will indicate that it has received a message Service is a program, routine, or process that performs a specific system function to support other programs, particularly at a low (close to the hardware) level

Client server architecture refers to a network architecture whereby every computer on the network is either a server or a client.
Explain the two main reason for using layered protocol architecture for network communication?
1. Protocol layering is a common technique to simplify networking designs by dividing them into functional layers, and assigning protocols to perform each layer's task.
For example, it is common to separate the functions of data delivery and connection management into separate layers, and therefore separate protocols. Thus, one protocol is designed to perform data delivery, and another protocol, layered above the first, performs connection management. The data delivery protocol is fairly simple and knows nothing of connection management. The connection management protocol is also fairly simple, since it doesn't need to concern itself with data delivery.
2. Protocol layering produces simple protocols, each with a few well defined tasks. These protocols can then be assembled into a useful whole. Individual protocols can also be removed or replaced as needed for particular applications.
The most important layered protocol designs are the Internets original DoD model, and the OSI Seven Layer Model. The modern Internet represents a fusion of both models.

Dynamic ARP table entries are created whne a client makes an ARP request that cannot be satisfied by data already in the ARP table.
What do ports 135 and 137 information tell an attacker?
Ports 135 and ports 137 tell an attacker that the user has a Windows OS system. These ports are used by hackers.
Punch cards are a very old way of programming a computer. The punch card would have long rows of numbers, representing certain instructions. You would punch a hole through the number corresponding to the instruction you wanted to execute. You would then feed the card into the computer, and it would run the program.
What is the other name for a lan card?
NIC - Network Interface card (sometimes also called a network adaptor card).
A cable with a steel sheath.
AnswerArmoured cables are cables designed to by laid underground. An armoured cable is a cable whose conductors are protected from mechanical damage by an outer layer of steel tapes or wire. The armour itself is protected against corrosion by an outer waterproof layer. The steel tape or wire is wound around the cable to maintain its flexibility.
