In today’s world when whole world become digitized there is need not only to store and transmit data but security is also main concern i.e. transmission of data with high security. In earlier time there ware attempts to hide a message in trusted media so as to deliver it across the enemy territory[1]. In the modern time of digital communication, several methods are used for hiding information in any medium. There are many method one of such technique is steganography[2] in which digital images are

7.1 Description: An Internet Protocol address (IP address) is a numerical label assigned to each participating in a computer network that uses the Internet Protocol for communication. What is an IP address “IP address” is a shorter way of saying “Internet Protocol address.” IP addresses are the numbers assigned to computer network interfaces. Although we use names to refer to the things we seek on the Internet, such as www.example.org, computers translate these names into numerical addresses so

Chapter 5: Questions 3,4, and 8 9/29/2012 3. What are the parts of TCP/IP and what do they do? Who is the primary user of TCP/IP? TCP/IP has two parts. TCP is the transport layer protocol that links the application layer to the network layer. It performs segmenting: breaking the data into smaller PDUs called segments, numbering them, ensuring each segment is reliably delivered, and putting them in the proper order at the destination. IP is the network layer protocol and performs addressing

domain name rather than their IP addresses. IP addresses, which form the basis of addressing on the Internet and most other networks, each can contain as many as 12 digits under the currently mainstream IPv4 addressing scheme (or as many as 32 hexadecimal digits under the next-generation IPv6 addressing scheme). It can be difficult for humans to remember such addresses, but it is relatively easy for them to remember domain names, which typically use alphabetic characters and consist of words, abbreviations

used by SQL servers. 14. Answer C is correct. The address is an example of the iSCSI Qualified Name, which isthe most commonly used iSCSI address. Answer A is incorrect because the MACaddresses used to identify network cards are 48-bits/12 hexadecimal numbers. AnswerB is incorrect because an IPv4 address is a 32-bit address consisting of four 8-bitoctets, each octet ranging from 0-255. Answer D is incorrect because the ExtendedUnique Identifier is another addressing scheme used by iSCSI

2.5 SQL Injection SQL Injection is a code injection technique, used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker) [13]. SQL Injection must exploit a security vulnerability in an application's software, for example, when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and unexpectedly

Assignment 10.1 Type pf networks Type of networks What it is? How it works? Local area network Local area network is a group of desktop computers linked through a network that are all located at a single business site. The LANS can have more than 100 users. Users can use printing and other kind of services needed through applications run on the lan server. Can be used as web server. It can also be shared to others at the same lan. Metropolitan area network Metropolitan area network is a high speed

Data Link and Network Layer Protocols in TCP/IP Protocol Difference Between Ethernet II and Ethernet 802.2 LLC Frame Structures Ethernet II framing structure is also commonly referred to as DIX Ethernet (Carrell, Chappell, Tittel & Pyles, 2013). This frame structure was developed by DEC, Intel, and Xerox and thus the DIX acronym that represent these major players in its development (Carrell et al., 2013). The Ethernet II defines a two-octet field of EtherType (Carrell et al., 2013). The MAC address

1. Introduction Media Access control address is a permanent/fixed address which is assigned to every hardware device connected to a network (wireless adapter, network interface card etc.) by the hardware manufacturer. Every device on a network has an ip address, IP is an internet protocol which give unique identity to the devices at network layer. IP address can be frequently changed. One the other side, MAC addresses are permanent and they work at layer 2 (data link layer). MAC Address is also known
