Computer Networking

unshielded twisted pair (utp)

The most popular connectors found these days on the ends of network cables are commonly called RJ45 connectors.

The internet is one example of a "Computer Network." As a result, then a computer which is connected to the internet is connected to a "Computer Network"

There are other types of computer networks which are not necessarily connected to the internet, such as some offices.

Typically you can be assured that your computer is connected to a computer network if:

(a) you are using the internet

(b) you are using a modem (many varieties include, but not limited to Telephone, Cellular, etc.)

(c) you are connected to a wall outlet, box, or other device with an "Ethernet" cable. (The ends of an Ethernet cable look the same as a phone cable, only wider (8 wires instead of 4)

Also . . . just because the "wires" are connected, doesn't mean that your computer is actually "participating" in the network . . . software, hardware, drivers . . . all these things have to be in place & working correctly for a full fledged network connection.yes irt i s1

On Windows you go to

Start > Run > Type "cmd" without the quotes

ENTER

type "ping ", followed by the IP address of the server you want to ping.

ex. "ping www.google.be"

ENTER

The response time is your ping. (basically it's a measurement of time needed to send a signal between your PC & another PC or device.)

Any networking issue is a combination of software and hardware configuration. The version of NOVELL at your work may be based on an IPX based communications scheme, while it is almost certain that your home network is based on TCP/IP. You can get your laptop to handle this, but it will take installing another network card, installing the hardware driver for the card, and then answering some configuration questions, like the address of the router, or cable modem for your home. This is really a place for a professional to look at the details of each system, and make the adjustments. It can be easy, or complex, so there is no simple way to answer your question.

If both of your computers (both PC + laptop) do not run on TCP/IP, this could cause major problems, as if the two use different communication protocols they can not communicate with one another. another problem may be that you don't have a NIC (Network Interface Card).

same as my modren but i know no what is wrong and hpw to fix it , do u know no how to fix it ?

In networking terms a server is a PC that contains information (usually for a business) and can share that information to other computers on the same network. The individual Computers are called Clients.

Setting up your router's wireless security is the best way to prevent other people from using your wireless Internet connection. Your Linksys router supports three (3) of the most commonly used wireless security types: WEP, WPA and WPA2 Personal.

WEP is out dated. Try the using WPA and WPA2 wireless security setting types

Configuration management is the process for ensuring an item performs consistently. The software may be purchased at Amazon, or open source software can be downloaded at a variety of websites.

Integers are represented as a string of 1's and 0's. The bits (a single one or zero) are weighted by powers of two, so the one on the far right has value 20 or 1, the second is 21 or 2, third is 22 or 4, 4th is 8, 5th is 16, etc. An integer in a modern computer is typically 32 bits long, or 4 bytes (a byte is 8 bits).

Negative numbers are represented in two's complement form, which is a little complicated to explain here, but if you google it there are good websites. The reason that 2's complement form is used versus simpler sign-magnitude are that it makes the math easier for a computer's processor.

The network device that regenerates data signals without segmenting the network is a repeater. Repeaters are used to prevent attenuation of signals.

Novell owns the IPX/SPX protocol.

The main communication or network protocol is the TCP/IP protocol. (Transmission Control Protocol/Internet Protocol)

They send the message again, generated by a random time, so the don't collide again.

There are numerous advantages of file transfer protocol and one of it is the capability to transfer big chunks of files from one unit to another. Also, with file transfer protocol, data is being transferred back and forth through a same server from both sides.

The protocol used for handling TCP traffic through a proxy server is called SOCKS, which means \"Socket Secure\".

You send it using the address of the persons house to the person your writing to. You just use the persons name your sending it to.

To avoid any chance of misunderstanding, it is also common practice to do the following. After your addressee's name, and before the address they're staying at, place the name of the principal resident at that address, prefixing it with "In care of" or the abbreviation "c/o". For example:Mike Smith

c/o Mrs. Ethel Miller

123 4th St.

Big City, NY 00000

A crossover cable is used to connect a Hub or Switch to another Hub or Switch - or a PC to another PC.

That would depend on what you mean by address. If you mean the group of numbers e.g. 192.168.1.1 then this is the network address and it is the unique address of the computer or device upon a network - there are three classes of the types of IP (Internet Protocol) addresses for use in internal and external networks, those with an address starting 192.168.x.x are three main classes of IPv4. Class C are for internal networks with less than 254 devices and always start 192.168.x.x Class B are for larger private networks and start 10.10.x.x and Class A are for internet connection and are issued to you by your ISP. There are reserved IP addresses e.g. 127.0.0.0 is the device's internal IP address.

== == Disadvantages of a peer to peer network: * the system is not centralised, making administration difficult * lack of security * no computer in the network is reliable Therefore, peer-to-peer networks are only useful for a small number of computers (generally about 10), and only suitable for applications that do not require a high level of security (it is not advisable in a business network containing sensitive data).
Some of the disadvantages of peer to peer networking not being able to recover files and security is vulnerable. Also peer to peer networking is not centralized making it hard to control.

The four octets make up a complete address. The first part refers to a network, the remainder an individual computer in a host; however, the exact size of this "first part" may vary.

For network devices, in most cases yes. Operating systems do not need to rely on SNMP, and in the case of Microsoft, it's recommended against for security reasons.

Ftp is NOT a secure protocol. All usernames and passwords exchanged in setting up an FTP connection are sent in cleartext, data exchanged over and FTP connection is not encryption and the connection is subject to hijacking. A SFTP protocol however, is secure, thus your information is far safer.
