It is a text message that may contain files, images or other attachment sent through a network to a specified individual or group of individuals. Some early e-mail systems required that the sender and the recipient both be online at the same time, in common with instant messaging. Today\u2019s e-mail systems are based on a store and forward model. E-mail servers accept, forward, deliver and store messages.<\/p>\n<p>Neither the user nor their computers are required to be online simultaneously; they need to connect an e-mail server, for as long as it takes to send or receive messages. Interaction between e-mail server and clients are governed by e-mail protocol. The two most common e-mail protocols are POP3 and SMTP.<\/p>\n<p><strong>SMS<\/strong><br \/>\nSMS stands for Short Message Service. Short text messages are transmitted to and from a mobile phone, fax machine, etc. Message must not be longer than 160 alpha-numeric characters and may also contain images or graphics. Once a message is sent, it is received by a Short Message Service Centre (SMSC), which must get to the appropriate mobile device. To do this, the SMSC sends a SMS request to Home Location Register (HLR) to find the roaming customer. Once the HLR receives the request, it will respond to the SMSC with the subscriber\u2019s status<\/p>\n<ul>\n<li>Inactive or active.<\/li>\n<li>Where subscriber is in roaming.<\/li>\n<\/ul>\n<p>If the response is \u2018inactive\u2019, then the SMSC will hold on to the message for a period of time. When the subscriber access his device, the HLR sends a SMS notification to the SMSC and the SMSC will attempt delivery.<\/p>\n<p>The system pages the device and if it responds, the message gets delivered. The SMSC receives a verification, that the message was received by the end user, then it is categorised as, send message and will not attempt to send again.<\/p>\n<p><strong>2 Marks Questions<\/strong><\/p>\n<p>Question 37.<br \/>\nIdentify the following devices:<br \/>\n(i) Devices that are used to connect different types of networks.

(Delhi 2014)<br \/>\nAnswer:<br \/>\nStar topology<\/p>\n<p>Question 41.<br \/>\nWhat is meant by \u201cDenial of Service\u201d with reference to Internet service? (Delhi 2014)<br \/>\nAnswer:<br \/>\nDenial of Service It is a type of attack in which a machine or network resource is made unavailable to the intended users. DOS attacks generally do not allow the attacker to access or modify information on the computer system or in the physical world.<br \/>\nThe different forms of Denial of Service attacks are as follows:<\/p>\n<ul>\n<li>Denial of Access to Information<\/li>\n<li>Deinal of Access to Communications<\/li>\n<li>Deinal of Access to Systems<\/li>\n<li>Deinal of Access to Applications<\/li>\n<\/ul>\n<p>Question 42.<br \/>\nList two measures to secure a computer network? (All India 2014C)<br \/>\nAnswer:<br \/>\n<strong>1. Denial of Service (DOS)<\/strong><br \/>\nA denial of service attack refers to an attempt to make computer resources unavailable to the intended users. Generally, it consists of the effort of a person or a group of persons to prevent an Internet site or service from functioning efficiently or completely. It may be temporarily or infinitely.<\/p>\n<p>One of the common methods of denial of service attack is to saturate the target machine with external communication requests, in such a way that either the machine can not respond properly or respond slowly that is would not send services effectively.<\/p>\n<p><strong>2. Intrusion Problem<\/strong><br \/>\nThe intrusion problem refers to the malicious activities or policy violation performed on a computer system. The main motive of intrusion is to tress vital information and essential data. Such type of activities are performed by the people having malicious mentality.<\/p>\n<ul>\n<li>Intrusion Detection System It is a device or software application that monitors the network for malicious activities. The intrusion detection and prevention system is primarily focused on identifying possible incidents, logging information and reporting attempts.<\/li>\n<li>Snooping It refers to unauthorised opening of files or accessing data, e-mail, etc. Snooping may include monitoring and tracing of keystrokes pressed, capturing the passwords and login information, etc.<\/li>\n<li>Eavesdropping It is identical to snooping. When there is intentional interception of other data such as e-mail, login-id, credit card information, password, etc., then it is said to be eavesdropping. In other words, when someone listens or intercepts others data secretly, then it is said to be eavesdropping.<\/li>\n<\/ul>\n<p>Question 43.<br \/>\nWhat do you understand by Network Security? Name two common threats to it. (Delhi 2013)<br \/>\nAnswer:<br \/>\nNetwork security is needed to protect data during its transmission and to guarantee that data transmission is authentic.<br \/>\nTwo common threats are:<\/p>\n<ul>\n<li>Intrusion Problem.<\/li>\n<li>Denial of Service Attacks.<\/li>\n<\/ul>\n<p>Question 44.<br \/>\nWrite one advantage of star topology over bus topology and one advantage of bus topology over star topology. (Delhi 2013)<br \/>\nAnswer:<br \/>\nAdvantage of star topology over bus topology The star topology is the most reliable as there is a direct connection of every node in the network with the central node, so any problem in any node will affect the particular node only.<\/p>\n<p>Advantage of bus topology over star topology Extension of network is very easy in bus topology, we can connect new node along its length.<\/p>\n<p>Question 45.<br \/>\nWhat is MAC address? What is the difference between MAC address and an IP address? (Delhi 2013)<br \/>\nAnswer:<br \/>\nMAC Address A MAC address is an essentially unique number associated with a network card in a machine. It serves as a convenient way to distinguish between two different computers. A MAC address consists of 48 bits, usually represented as a string of 12 hexadecimal digits (0 to 9, a to f or A to F); these are often grouped into pairs separated by colons or dashes, e.g. the Mac address 001B638445E6 may be given as 00:1 b:63:84:45:e6 or as 00-1B-63-84-45-E6.<\/p>\n<p>IP Address Computers on the Internet need to find one another in order to communicate. Each computer, therefore, has a unique identifying number known as an IP address. Examples of IP address are 22.231.113.64 or 194.66.82.11. An IP address always has four numbers separated by dots. Each number has a value of 0 to 255.<\/p>\n<p>Question 46.<br \/>\nIdentify domain name and URL from the following: (Delhi 2012)<\/p>\n<pre>http:\/\/www.he1 pingeachother.1n\/home\/aboutus.htm<\/pre>\n<p>Answer:<br \/>\nDomain Name<\/p>\n<pre>www.helpingeachother. in<\/pre>\n<p>URL Name.<\/p>\n<pre>http:\/\/www.helpingeachother.in\/home\/ aboutus.htm<\/pre>\n<p>Question 47.<br \/>\nGive a suitable example of URL and domain name.

(Delhi 2012)<br \/>\nAnswer:<br \/>\nOne advantage of star topology over bus topology is that in star topology there is separate connection between the server and individual devices. That\u2019s why failure of one node does not affect the rest of network, whereas in bus topology all the nodes are connected over a single line. Due to this, if there is a problem in communication anywhere in the network with any node, the entire network will stop functioning.<\/p>\n<p>Question 49.<br \/>\nGive an advantage of using star topology over bus topology. Show a network layout of star topology to connect 5 computers. (All India 2012)<br \/>\nAnswer:<br \/>\nAdvantage of star topology over bus topology The star topology is the most reliable as there is a direct connection of every node in the network with the central node, so any problem in any node will affect the particular node only.<\/p>\n<p>Advantage of bus topology over star topology Extension of network is very easy in bus topology, we can connect new node along its length.<\/p>\n<p>The network layout to show a connection of five computers using star topology is as follows:<br \/>\n<img loading=\"lazy\" class=\"alignnone size-full wp-image-125701\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2021\/12\/Informatics-Practices-Class-12-Important-Questions-Chapter-1-Computer-Networking-1.png\" alt=\"Informatics Practices Class 12 Important Questions Chapter 1 Computer Networking 1\" width=\"209\" height=\"137\" \/><\/p>\n<p>Question 50.<br \/>\nMr. Kavye Shastri, General Manager of Unit Nations corporate recently discovered that the communication between his company\u2019s accounts office and HR office is extremely slow and signals drop quite frequently.

Define domain name.<br \/>\nAnswer:<br \/>\nThe security issues over a network are:<\/p>\n<ol>\n<li>Computer worms and viruses remain the most common security threat, which could damage the data or corrupt the files in the computer.<\/li>\n<li>Information theft is a big concern, i.e. the theft of many delicate personal file or official files.<\/li>\n<\/ol>\n<p>Question 71.<br \/>\nDefine domain name.<br \/>\nAnswer:<br \/>\n<strong>Domain Name<\/strong><br \/>\nDomain name is a unique name or identification that helps to create the path to open a particular website. All the domain names have IP addresses. IP address can be remembered by the computer, but it is difficult to remember for a human being. If you know that URL (Uniform Resource Locator) of a website, you can access it. The URL is actually the domain name of website, so the domain name is unique name of a website. Every time we enter a domain name it will be converted into an IP address and the website will be opened,<\/p>\n<pre>E.g., www.Mybook.com<\/pre>\n<p><strong>A domain name contains three parts:<\/strong><\/p>\n<ul>\n<li>Hostname as, www<\/li>\n<li>Name describing the website purpose as, Mybook<\/li>\n<li>Top level domain as .com, .net, .edu, etc.<\/li>\n<\/ul>\n<p>We hope the Informatics Practices Class 12 Important Questions Chapter 1 Computer Networking help you.
