static IP address- administratively assignment of IP address.
dynamic - assigning the IP address dynamically by using DHCP.

Its Repeater, it can amplify the signals strength.

Basically when our signal is weak (on a network) then we should have a repeater device. This device used to regenerate the weak signal.

As far as I know this term is used for items that needs to be picked from various locations in a warehouse whenever a customer fills the shopping cart and & submits the list for purchase.

Hi,
Its too simply to IIS backup. Take the system state backup in that only IIS will be consider, if the server is IIS.

For connecting the Switch to Modem we use standard cable in any version of UDP (cat 1.2.3.4.5.5e.6)

Straight cable.

If we use different devices we can use straight cable.
If we use same devices we can use cross cable

Ans :-There is major difference between IP V.4 and IP V.6 such as – 1.In IP V.4 is a 32 bits IP Address but IP v.6 128 bits IP Address. 2.IP v.4 is a Decimal Format, but IP V.6 is Hexa-Decimal Numbe...

IPv4 means Internet Protocol version 4, whereas IPv6 means Internet Protocol version 6. IPv4 is 32 bits IP address that we use commonly, it can be 192.168.8.1, 10.3.4.5 or other 32 bits IP addresses....

DORA stands for Discover Offer Request Ack When there is request been sent from the client and there should be a response should be sent from the the server, So the process discovering the request b...

no because Infrastructure master performs its task by comparing its state against the state of a GC - and updates other DCs in the same domain based on the outcome. Effectively, the update would never took place since no differences would be detected.

This is because different types of devices use different ways of communicating to hosts. Routers for example use the IP or logical address whereas level 2 switches and older HUBS use the MAC address to communicate.

IP Address : Its a 32-bit unique numeric identifier assigned to every host on the network. Its a logical address of any TCP/IP host or a machine (computer).IP address helps a system to be uniquely ide...

If someone is using a laptop they may have accidentally turned their wifi connection off. This is fixed by:

Looking for the wifi connection button on the top row of the keyboard. It looks similar to the letter A surrounded by parenthesis. Push it to turn the wifi connection back on.

I would ask them to do the following steps.

Step 1. Reset / Restart the Modem.
If no connection then

Step 2. Reset Network Connection / Restart the PC
If not connection then

Internet is global network or in other words we can say it is WAN. But Ethernet is a medium that is used to connect computers in a LAN. These computers may be hosts or clients.

A ACL is a Active Control List - So you specify a rule in a list of rules that data on a certain ip and or port can access another port and or ip address.  In essence its more like a rule in a ro...

ACL Manager lets you control routers and firewalls from your PC . Deploy the same access list to different device types such as Cisco and Juniper. Save time and money in router ACL management. Manage thousands of routers from a single application. Minimize errors in ACL deployment.
