Local Area Network

Wide area network generally consist of two or more local networks . Computers connected to a WAN are often connected through public Computers connected to a wide-area network are often connected through public networks, such as the telephone system. Wanos network less the costs and accelerate more network speeds. Like this you can get more provider those are providing WAN services.

there are two types of addresses: network addresses and physical addresses

First, pick out the address you wish to permanently assign to the workstation, plus the subnet mask you are going to use.

Then, bring up the network adaptor properties and put the address in the dialog box (for Windows).

For Unix/Linux systems, using the ifconfig command allows you to assign a static address (see first part above) to any adaptor.

It depends on what SSL is being used for (HTTP, as in secure web pages; FTP; Telnet; etc.). Below is a non-exhaustive list of various port numbers used for protocols with SSL implemented: * HTTP: Port 443 * FTP (Data): Port 989 * FTP (Control): Port 990 * Telnet: Port 992 * IRC: Port 994 * pop3: Port 995 I hope this was the information you were looking for.

Most LANs use UTP cable, category 5 or better.

First you need a crossover Ethernet cable which connects Transmit lines to Receive and Receive lines to Transmit on a 10/100BaseT connection. Both computers need to have Ethernet IP address set in same range (e.g. 10.0.0.x) and same Subnet Mask and Gateway. e.g. IP address can be 10.0.0.5 on one machine and on other it can be 10.0.0.7 .. After that both computers connected to each other through a cross cable can see each other and transfer/share data.

Full form of PING is:

Packet InterNet Groper

PING: Ping is defines as " the tools which is used to check the communication of between the systems, routers switches and also the Internet".

the syntax is:

ping ip address (or) ping system name (or) ping device name

The abbreviation of PING is : "Packet InterNet Goopher"

Character-oriented protocols are also known as byte oriented protocols. They are used in variable size framing by the Data link layer for data link control.

Data are 8-bit characters encoded in ASCII. Along with the header and the trailer, 2 flags are included in each frame (beginning and end of frame) to separate it from other frames. These flags are protocol dependent characters.

The important issue is how to differentiate when the data in the frame is the same as the flag? This means that how is the Receiver going to know that the frame content is actually the data not the flag?

A solution is to use a process called BYTE STUFFING. An extra byte is added to the data section of the frame, where the character sequence is the same as the flag. This is usually the escape character: ESC.

Of course if the data section also includes same sequence of characters as ESC another ESC character will be added to tell the receiver which section is data.

At receiver's end, this data section will be removed and be treated as a piece of data.

Clearly, this procedure does not account for 16-bit or 32-bit characters we use today, so we rely on bit-stuffing protocols (mostly).

LAN is internal. IE, your computer, router, modem.

WAN is external, such as your computer, a server on the internet, a corporate database.

Not to be confused with WLAN, which is wireless LAN

The minimum number of ports on most brands of switches is four. While there is no industry rule that limits the number of ports on a single switch, practical application has shown that a minimum of four ports is about right.

High-end layer 3 switches or routers

I had to create patch cables in my Infotech class and had to memorize at least straight cables. starting from pin 1 (left to right)

Straight-Through: White-Green, Green, White-Orange, Blue, White-Blue, Orange, White-Brown, Brown

White-Green is pin 1 and Brown is pin 8

Cross-Over Cable: White-Orange, Orange, White-Green, Blue, White-Blue, Green, White-Brown, Brown

UDP - primarily for speed is used to transport voice packets in a VoIP deployment.

Nord VPN is the best, I have personally use this for over 10 years and I found them to be very reliable, fast and affordable. CAN EVEN GET A PLAN FOR LESS THAN 4 USD PER MOTHS.

An employee downloads a file that is stored on a departmental file server.

A thin coaxial cable that is used as a connector is also called a thinnet. It is popular in linear bus networks.

It isn't a question of advantages and disadvantages; a protocol is an agreed-upon set of rules. These rules are designed to allow (in the case of networks) an agreed-upon framework for communication of nodes within a network.

These rules are worked on by committees, representing users and companies world-wide.

10BASE2 is a variant of Ethernet that uses thin coaxial cable. The 10 comes from the maximum transmission speed of 10 millions of bits per second, The BASE stands for baseband signaling, and the 2 supposedly refers to the maximum cable length of 200 meters.

In case of IPv4, the address has 4 bytes. In case of IPv6, the address has 16 bytes.
