In its simplest form an Array is a series of hard disks conected to one desktop computer.
More complex Arrays can be Redundant Array Inexpensive Disks or the Array could be Network Attached Storage depending on what the network requirements are.
What does the term aironet mean?
Aironet, a division of Cisco Systems acquired by Cisco Systems in 1999 , is a company providing wireless networking devices. Aironet Wireless Communications was started in 1986 by ex-Marconi Wireless employees.
What is the help command in the cisco ios?
The question mark. It can be used in different contexts, for example:
?
(list all commands that make sense in the current context)
s?
(list all commands that start with s)
show ?
(list what options you have as the second word after the SHOW command, for example, show ip, show running-config, etc.)
1. Frame Relay
2. HDLC
3. PPP
In communication and computer network research, network simulation is a technique whereby a software program models the behavior of a network by calculating the interaction between the different network entities (routers, switches, nodes, access points, links etc.). Most simulators use discrete event simulation - the modeling of systems in which state variables change at discrete points in time.
There are both free/open-source and proprietary network simulators available. Examples of notable network simulators / emulators include:
Both commercial tools are available at deeply discounted prices to universities.
The advantage is in fault detection; in a bus topology any break in any wire segment would cause the entire LAN to fail. With a star topology, a break in any wire segment only affects the one client connected to the network.
What is the function of a VTP server?
In very simple language. Cisco switches can be configured in VTP Server, transparent or client mode. VTP server is the default mode in most everyday switches. The switch must be in server mode in order to create,add, delete VLAN's in the same domain.
If I am using more than one switch, the one with the lowest MAC address is the one I would use to be my STP. The other switch would be in CLIENT mode (my preference).
What is the default password to the Cisco 2611?
The factory default login and password on the Cisco 1721 router is Cisco. This is usually written in the manual of the router or somewhere in the packaging of the device.
NVRAM is Non-Volatile Random Access Memory. That means that it can be read or written to as desired, and that it can hold data when there is no power.
How do you control a system using ip address?
you can not just control a system using ip address.(thats hacking)
you would to use progames like network admin tool
When is the uplink connection used on a switch?
Uplink connections are typically used to connect the switch to a higher level switch, that is more powerful and closer to the backbone.
On basic switch models, the regular ports are MDIX ports, meant to connect directly to a PC. The Uplink port is then an MDI port, which can connect (with a straight cable) to an MDIX port on a different switch. Often the highest numbered port (8, 16, or 24 for instance) has one MDIX port in the regular set and an MDI uplink next to it, but you can only use one of these two.
You can use a crossover cable to connect MDIX to MDIX or MDI to MDI port.
On more modern switches, ports are often MDI/MDIX autosensing and this reason for existence of uplink ports has passed (all Gigabit Ethernet has this, and many 100 Mbit Ethernet).
In the mean time, however, switch models have come into being which have faster speed uplink ports. For instance, 10 Mbit switches with 1 or 2 100 Mbit ports to connect to the core network, or these days 100 Mbit switches with a few Gigabit ports.
Proper console cable
Terminal emulation software
Can a routing table in a datagram network have two entries with the same destination address?
In a datagram network, the destination addresses are unique. They cannot be duplicated in the routing table.
cual es el proposito de los protocolos de enrutamiento?
What ip address has the subnet mask 99.0.0.0?
i feel there is a typo in the question itself because in general the subnet masks can have any value between 255.0.0.0 and 255.255.255.252 .
routing between VLANs
Is Networxx Khawar Butt is Penta CCIE or he scam or is legitimate?
I was a student of this institute as well. I was duped by the fact that since this was owned by Khawar Butt, i would actually learn networking. Joining this institute is the biggest mistake of my life. I regret spending so much time and money. Before i joined this institute, i thought i would come out a successful person in this field, but now my dreams are totally shattered. The J.P nagar branch especially is completely bogus. they have no skilled instructors and the director here is only behind your money. I hope they will be made to pay for playing with students careers. Strict action should be taken against them.
In that way it's much easier to control network, maintenance, and control user computers.
How do I get the answers for cisco packet tracers?
you need to answer it, for sure you get the answer.
