question

What is an IP address and where I can find the IP address for my computer?

answer

An IP address is a unique number identification assigned to each computer, server, or device connected to the Internet. To find your IP address, go to Google and type "what is my IP."

question

An IP address

answer

is a unique identification number assigned to each computer, server, or device connected to the Internet. A typical IP address is expressed as a series of numbers separated by decimal points, such as 197.169.73.63, and is called a dotted decimal number. Internet Corporation for Assigned Names and Numbers (ICANN) is responsible for allocating IP addresses to network administrators. To find your IP address, go Google and type "what is my IP."

question

2. Does the IP address remain the same or can it change automatically?

answer

The IP address changes automatically if your computer has a dynamic IP address. A dynamic IP address is a temporary IP address and is assigned by your ISP when your computer connects to the Internet.

question

Dynamic addressing

answer

is a temporary IP address assigned to you by your ISP from an available pool of IP addresses. It is assigned by the dynamic host configuration protocol (DHCP) each time you log on to the Internet. IP addresses can also be assigned statically. Static addressing means that the IP address for a computer never changes and is most likely assigned manually by a network administrator.

question

Is there an alternative to remembering IP addresses?

answer

Yes, you can use a domain name. A domain name is simply a name that takes the place of an IP address, making it easier to remember.

question

A domain name

answer

is simply a name that takes the place of an IP address, making it easier for people to remember it. Yahoo.com and Aol.com are domain names. Domains are organized by level. The portion of the domain name after the dot is the top-level domain (TLD), such as .com. Within the top-level domain are many second-level domains, such as Amazon.com and Microsoft.com.

question

But how do computers get the IP address from a domain name?

answer

Computers consult the domain name system (DNS) server. The DNS server contains a mapping of domain names with their corresponding IP addresses.

question

When you enter a domain name into a web browser

answer

your computer converts the domain name into an IP address by consulting a database maintained on a DNS server, which functions like a phone book for the Internet. Your ISP's web server has a default DNS server that it goes to when it needs to translate a domain name into an IP address. Your ISP or network administrator defines the default DNS server.

question

What if the ISP's web server cannot locate the IP information on the default DNS server?

answer

The default DNS server contacts one of the DNS servers. A root DNS server knows the location of all the DNS servers that contain the master listings for an entire top-level domain.

question

The default DNS server

answer

contacts one of the root DNS servers. A root DNS server knows the location of all the DNS servers that contain the master listings for an entire top-level domain. Your ISP's default DNS server receives the information from the master DNS server. It then stores that information for further reference and passes it on to the ISP web server as well as communicates the appropriate IP address to your computer.

question

When my friend connects to my computer, how is data transferred?

answer

Computers communicate efficiently using the communication methodology called packet switching.

question

Packet switching

answer

is the communications methodology that makes computer communication efficient. In packet switching, data is broken into smaller chunks called packets, which are sent over various routes at the same time. Packet switching doesn't require that a dedicated communications circuit be maintained.

question

If data is broken into chunks and sent over various routes at the same time, how do these packets reach their destination?

answer

The packets contain destination information and are reassembled when they all reach the destination.

question

The packets

answer

contain destination information and are reassembled when they reach the destination. Packet contents vary depending on the protocol being followed. At a minimum, all packets must contain an address to which the packet is being sent, the address from where the packet originates, reassembling instructions if the original data was split between packets, and the data that is being transmitted.

question

How do packets travel through the Internet?

answer

Packets are routed using Transmission Control Protocol/Internet Protocol (TCP/IP). TCP/IP is a suite of protocols used to route packets over the Internet.

question

TCP/IP

answer

is a suite of protocols used to route packets over the Internet, not encrypt files. The suite is named after the original two protocols, the Transmission Control Protocol (TCP) and the Internet Protocol (IP). The suite actually comprises many protocols like user datagram protocol (UDP), file transfer protocol (FTP), Telnet, hypertext transfer protocol (HTTP), secure HTTP (S-HTTP), and simple mail transfer protocol (SMTP).

question

circuit switching

answer

A dedicated connection is formed between two points (such as two people on telephones), and the connection remains active for the duration of the transmission.

question

classless interdomain routing (CIDR)

answer

Because the unique IP addressing system offers only a fixed number of IP addresses, a different addressing scheme known as classless interdomain routing (CIDR) allows a single IP address to represent several unique IP addresses by adding a network prefix (a slash and a number) to the end of the last octet.

question

computer protocol

answer

A set of rules for exchanging electronic information.

question

connectionless protocol

answer

Does not require any type of connection to be established or maintained between two computers that are exchanging information.

question

connection-oriented protocol

answer

Simply a name that takes the place of an IP address, making it easier for people to remember.

question

dotted decimal number (or dotted quad)

answer

A typical IP address is expressed as follows: 197.169.73.63

question

DNS (domain name system)

answer

When you enter the URL in your browser, your computer must convert the URL to an IP address. To do this, your computer consults a database that is maintained on a DNS (domain name system) server that functions like a phone book for the Internet.

question

dynamic addressing

answer

Your computer is assigned an address from an available pool of IP addresses; more common addressing.

question

dynamic host configuration protocol (DHCP)

answer

Dynamic addressing is normally handled by the dynamic host configuration protocol (DHCP), which belongs to the TCP/IP protocol suite. DHCP takes a pool of IP addresses and shares them with hosts on the network on an as-needed basis.

question

handshaking

answer

A connection-oriented protocol requires two computers to exchange control packets, thereby setting up the parameters of the data exchange session, before sending packets that contain data. This process is referred to as handshaking.

question

question

Internet Protocol version 4 (IPv4)

answer

The original IP addressing scheme created in the early 1980s.

question

Internet Protocol version 6 (IPv6)

answer

An IP addressing scheme developed by the Internet Engineering Task Force (IETF) to make IP addresses longer, thereby providing more available IP addresses. IPv6 uses 8 groups of 16-bit numbers, referred to as hexadecimal notation (hex for short).

question

IP address

answer

A unique identification number that defines each computer, service, or other device that connects to the Internet.

question

negative acknowledgment (NAK)

answer

If the packet is unreadable (damaged in transit), then Y sends a negative acknowledgment (NAK) to X, indicating the packet was not received in understandable form. X then retransmits that packet.

question

network prefix

answer

A slash and a number at the end of the last octet. The network prefix identifies how many of the possible 32 bits in a traditional IP address are to be used as the unique identifier, leaving the remaining bits to identify the specific host.

question

open system

answer

In an open system, its design would be made public for access by any interested party.

question

packet (or data packet)

answer

With packet switching, data is broken into smaller chunks (each one called a packet or a data packet) that are sent over various routes at the same time.

question

packet switching

answer

The communications methodology that makes computer communication efficient.

question

positive acknowledgment (ACK)

answer

Assume that two systems, X and Y, have established a connection. When Y receives a data packet that it can read from X, it sends back a positive acknowledgment (ACK). If X does not receive an ACK in an appropriate period of time, it resends the packet.

question

proprietary system

answer

This proprietary or private system model was the norm for Internet protocol.

question

root DNS server

answer

There are 13 root DNS servers maintained throughout the Internet. Each root DNS server knows the location of all the DNS servers that contain the master listings for an entire top-level domain.

question

second-level domain

answer

Within each top-level domain are many second-level domains. A second-level domain needs to be unique within its own top-level domain but not necessarily unique to all top-level domains.

question

static addressing

answer

Means that the IP address for a computer never changes and is most likely assigned manually by a network administrator or ISP.

question

question

What is SMTP?

answer

Simple mail transfer protocol (SMTP) is the protocol responsible for sending e-mail messages from an e-mail client to an e-mail server.

question

SMTP

answer

is the protocol responsible for sending e-mail messages from an e-mail client to an e-mail server of an Internet Service Provider (ISP) or a company website. Users get their SMTP server information from their ISP when they first set up their e-mail.

question

What's an e-mail client and e-mail server?

answer

An e-mail client is an e-mailing application (such as Microsoft Outlook) from which an e-mail message is sent, and an e-mail server is a specialized computer that stores, processes, and sends e-mails.

question

An e-mail client

answer

is not a computer but rather the e-mailing application (such as Microsoft Outlook) from which an e-mail is sent. An e-mail server is not e-mailing software but rather a specialized computer that stores, processes, and sends e-mails. All e-mail has to pass through e-mail servers.

question

When I attach a file to my e-mail, will SMTP send it to the e-mail server?

answer

The multipurpose Internet mail extensions (MIME) protocol is responsible for sending e-mail file attachments.

question

The multipurpose Internet mail extensions (MIME) protocol

answer

is responsible for sending e-mail file attachments. The MIME specification was introduced in 1991 to simplify attachments to e-mail messages. All e-mail client software now uses this protocol for attaching files. E-mail is still being sent in text, but the e-mail client using the MIME protocol now handles the encoding and decoding of e-mail file attachments for users.

question

Will SMTP keep my e-mails safe?

answer

No, SMTP cannot keep your e-mails safe, but there are other security measures like encryption that can keep your e-mails safe.

question

SMTP

answer

cannot keep your e-mails safe. Copies of your e-mail messages may exist temporarily or permanently on numerous servers as they make their way through the Internet. However, two options exist for protecting your sensitive e-mail messages: encryption and secure data transmission software.

question

How do I perform encryption?

answer

You can encrypt messages using private-key encryption. In private-key encryption, only the two parties involved in sending and receiving the message have the code.

question

In private-key encryption

answer

only the two parties involved in sending the message (not the server) have the code. This can be a simple shift code where letters of the alphabet are shifted to a new position. The main problem with private-key encryption is key security. If someone steals a copy of the code, the code is broken.

question

Is there any other safer way to encrypt emails?

answer

You can use public-key encryption. In public-key encryption, two keys are created, one key for encoding and the other for decoding.

question

In public-key encryption

answer

two keys are created one key for coding and the other for decoding. The key for coding is generally distributed as a public key. You can place this key on your website, for instance. Anyone wishing to send you a message codes it using your public key. When you receive the message, you use your private key to decode it.

question

Do instant messaging (IM) services use secure data transmission software to provide security of data exchanged?

answer

No, most instant messaging services don't use secure data transmission software. Hence it is not safe to exchange important data over IM.

question

Most IM services

answer

do not use encryption for IM messages, and the secure data transmission software used on e-mail does not work with IM programs. Therefore, it is not a good idea to send sensitive information using instant messaging because it is susceptible to interception and possible misuse by hackers.

question

e-mail servers

answer

Specialized computers whose sole function is to store, process, and send e-mail.

question

encryption

answer

Refers to the process of coding your e-mail so that only the person with the key to the code (the intended recipient) can decode (or decipher) and read the message.

question

key pair

answer

In public-key encryption, two keys, known as a key pair, are created.

question

multipurpose Internet mail extensions (MIME)

answer

A specification introduced in 1991 to simplify attachments to e-mail messages. All e-mail client software now uses this protocol to attach files.

question

Pretty Good Privacy (PGP)

answer

A tried-and-true public-key encryption package available for download; public-key encryption is the most commonly used encryption on the Internet.

question

private key

answer

When you receive the message, you use your private key to decode it. You are the only one who ever possesses the private key, and therefore it is highly secure. The keys are generated in such a way that they can work only with each other.

question

private-key encryption

answer

An encryption where only the two parties involved in sending the message have the code.

question

public key
