Q.1. What is the meaning of uploading? Give some guidelines for safe downloads.  (2 Marks)
Ans:
 Uploading: Uploading is the transmission of data or file from a local computer to a remote computer, as from your PC to a website you are constructing. It allows users to easily exchange files over networks.
Guidelines for safe downloads:

  • While downloading any file close all the applications that are running on your computer, let only one set-up file run at a time of downloading.

Q.2. Why do we need computer networks?  (2 Marks)
Ans:
(i) Networks enable resource sharing across the globe.
(ii) Networks provide high reliability by having alternate copies of data. Presence of multiple CPUs means that if one goes down, the others may be able to take over its work. This ability to work in the face of hardware problems is of atmost importance in military, banking, air traffic control, nuclear reactor safety, etc.
(iii) Networks enable a client/server model with clients as small computers, one per user, with data kept on one or more shared file server machines. Eg. Software installation can be on server and this can save cost of buying license for every machine.

Q.3. How are files downloaded?  (2 Marks)
Ans:
 

  • Downloading is transmitting data or file from a remote computer to a local computer. 
  • Downloading enables users to save files on their own computers. These files are downloaded using FTP (File Transfer Protocol).
  • We can also use HTTP to download files from the web.
  • From the internet client/user’s point of view, to download a file is to request it from another computer or from a web page on another computer and then receive or retrieve it.


Q.4. What is LAN?  (2 Marks)
Ans: 
A LAN (Local Area Network) connects network devices over a relatively short distance. A networked office building, school, or home usually contains a single LAN, though sometimes one building will contain a few small LANs (perhaps one per room), and occasionally a LAN will have span a group of nearby buildings.
In addition to operating in a limited space, LANs are also typically owned, controlled, and managed by a single person or organisation. They also tend to use certain connectivity technologies, primarily, Ethernet and Token Ring.

WANs tend to use technology like ATM, Frame Relay and X.25 for connectivity over the longer distances.

(i) Static IP Address: Static IP addresses are those types of IP address that never change once they are assigned to a device on a network. No doubt this type of addressing is cost effective but could have a high security risk. Static IP addresses are mostly used by web, email and gaming servers who don’t care much about hiding their locations.
(ii) Dynamic Address: A Dynamic IP address changes each time the device logs into a network. This kind of IP address is very tough to trace and are used by companies and business firms.

Each NIC (Network Interface Card) has a universally unique address assigned to it by its manufacturer. This address is known as the MAC (Media Access Control) address of the card. It means that a machine with a NIC can be identified uniquely through its NIC’s MAC address.
MAC address of an NIC is permanent and does never change. MAC addresses are 12-digit hexadecimal (6 bytes or 48 bit) numbers. By convention, MAC addresses are usually written in one of the following two formats:

(a) Free hosting
(b) Virtual or Shared hosting
(c) Dedicated hosting
(d) Colocation hosting

Q.19. What is DNS?  (2 Marks)
Ans:
It is practically impossible for a person to remember the IP addresses of all the computers one may have to communicate with. Therefore, a system has been developed which assigns names to some computers (web servers) and maintains a database of these names and corresponding IP addresses. These names are called Domain Names. Example: cbse.nic.in, sikkimipr.org, indianrailway.gov.in.

Q.20. Differentiate between a website and a web portal.  (2 Marks)
Ans:
Website is a location on the Internet, publicly accessible with a unique URL (web address). Webportal is a private location on the Internet, accessible with a unique URL (web address) and unique username and password.
