If both PCs have ethernet cards, the best cable to use would be a crossover cable. A crossover cable is almost the same thing as a regular ethernet cable, except the wires inside the connector are reversed on one end. This reversing of the wires allows you to connect a crossover cable between two PCs without any other network equipment like a switch or a hub.

Process switch is switch the process state between the status like read, blocked ,suspend. Mode switch is the switch the process privilege between the mode like use mode, kernel mode. Generally a mode switch is considered less expensive compared to a process switch.

They are used to connect various different pieces of equiptment to a console. Some of these could be USB ports for storage, controller ports, memory unit ports and sometimes ports to connect other devices.

To establish a connection with a secure Wi-Fi network, follow these steps:

1. Open your device's wireless settings.
2. Scan for available Wi-Fi networks.
3. Select the desired secured network.
4. Input the required security key or passphrase.
5. Confirm the details and wait for a connection to be established.

Once connected, you'll have access to the secure wireless network.

There may be a more general answer to this, but by default most Cisco hardware will support up to 1,000 VLANs.

If you are using a crossover cable, simply assign static IP's to each machine (192.168.0.2 and 192.168.0.3).

If using regular network cable, you will need to use a network switch or hub to connect them together, still using the static IP's for each machine.

Computers hold constantly changing values for entropy, for moments just like this.

In some computers, think smart-phones, the means of acquiring changing values even include gyroscopes as a mean of input.

I think I know what you are trying to do.

Spoof a MAC address, and get assigned a prohibited range?

That 'protocol' you ask about varies from vendor to vendor, the factors that determine entropy inputs/algorithms/assignment tasks vary from vendor to vendor.

You may get one particular vendors algorithm for example, by strenuously eliminating entropy factors, maintaining your constants, and by incrementing/decrementing those same entropy factors.

But you will never find yourself in the same environment twice, and brute-forcing a key will thence not work.

The bus topology is one of the four main topology types for networking. It allows systems to be connected in a straight line without any other network connectivity devices. As a result, it is easy to construct and needs very little in the way of configuration, and is inexpensive compared to other topologies.

The main result of any topology is to connect clients together in order to share resources.

Two different networks are connected by a router. Switches are used to connect network devices within networks.

Primary Means, it is individual there is no dependence, But Secondary will allays depends on Primary, If you want to do Secondary, you should complete primary first, There is no precondition to primary, but for Secondary Primary is the Precondition, first you should do primary, then only you are able to do secondary.

It keeps different applications data separate. It offers 3 different modes of communication. They are simplex, full duplex and half-duplex.
It is also used for tearing and establishing sessions between the host and destination.

interconnected networks is the basic meaning of internet...

it resembles a hierarchical network form...

Technically your question has a lot of unanswered questions: Is this a Windows PC? Is this a home or business ... you see my point? No one can fully answer this question with out knowing the network environment. In general - You need a TAP in the network; a TAP is a secure, known good, point from which to sniff the network traffic; simply trying to use host-based monitoring *may* not work correctly in all cases. Get a copy of WireShark -- get a clean (IE not infected PC) and learn how to use WireShark :) If you have a *lot* of traffic and you wish to *stop* or somehow control the flow of - then get a packet filtering stateful firewall. Or just hire a network security expert.

The most popular is the TCP/IP suite of protocols

In order to be media literate, you need to know the various forms of media, including newspapers, magazines, television, and alternative media, and be able to sort out what is reliable and what is not reliable.

RS232 is for point to point communication where as RS 485 is for multidpoint communication, Voltage level and speed differ

Hi frnds,,

There are few points which v can discuss on these are

1) Ya first main important point is RS232 is point to point communication n RS485 is multidrope communication which means ...

on RS232 u can not connect more than two device...

RS485 u can connect upto I think max 128 device theorically..(its depends on noise level as well as on distance and burd rate also)

Practicall as max 32...

2)Voltage level of RS232 is

-3 to -25 for 1

+3 to +25V for 0

while RS485 is based on differential voltage (0-5v) diff is 240mV for 1 and -240mV for 0.

3)distance limitation is 100meter for RS232 and 1Km for RS485,

4)noise immunity is high for RS485 as it is balance protocol and differencial protocol..

5)Software point of view u need to set transmit enable line in RS485 rest of the software is same...

6)pin for 232 is (Rx Tx and GND) while in case of RS485 it is (A(+) and B(-)) no need to transmit GND..signal

Since you were able to ask that question on the Internet I am assuming you already have access. If you want to hook up a wireless network then you need a router and a wireless network card in your system. The cable that you currently have to get on the internet will go into the router then another cable will come out of the router to the internet. The router will come with software for you to load. It is really not as hard a process as people think. You will set up a password on your wireless internet so only the people you want to get on it will be able to.

DNS is an application layer protocol. The application layer of the OSI model is the layer closest to the user and provides network services to the applications of the user. Examples of protocols that operate at the application layer are: DNS, FTP, TFTP, SNMP, TELNET, RLOGIN, SMTP, MIME, NFS, FINGER, BOOTP and SMB.

Yes. Each computer connected to the internet is assigned a unique internet protocol, or IP, address.
