II Define:
1) Internet: Internet is a global system
of interconnected computer networks using a common protocol (TCP/IP) through
telephone wires, fibre optic cables, wireless technologies, satellite links,
etc.
2) Web
Browser:
Web Browser or Internet browser is the program that is used to access internet
and view web pages on the computer. It is used to locate, retrieve and display
content of the World Wide Web, including Web pages, images, video and other
files.
3) Web
Server: A Web server is a computer system on Internet that uses HTTP (Hypertext
Transfer Protocol) to serve the Web pages to users, in response to their
requests, which are forwarded by their computer's browser. It is a computer
where the web content is stored. Basically, web server is used to host the web
sites but there exists other web servers also such as gaming, storage, FTP,
email etc.
4) Email: Electronic mail is the term
given to electronic message, usually a form of simple text message that a user
types in a computer system and is transmitted over network to another user. You
can also attach files to an email.
5) WWW: World Wide Web is a an information space where documents and
other web resources are identified by Uniform Resource Locators (URLs),
interlinked by hypertext links, and can be accessed via the Internet. It is a
system of Internet servers that supports documents formatted in mark-up
language called HTML that supports links to other documents as well as
graphics, audio and video files.
III Write
short note on:
1) IP
Address: An
Internet Protocol address (IP address) is a numerical label assigned to each device
(e.g., computer, smart phone, other devices) participating in a computer
network that uses the Internet Protocol for communication. It is used to
identify itself and communicate with other devices in the IP network. Any
device connected to the IP network must have an unique IP address within the
network.
There are two standards for
IP addresses: IP Version 4 (IPv4) and IP Version 6 (IPv6).
IPv4 uses 32 binary bits to create a single unique
address on the network. An IPv4 address is expressed by four numbers separated
by dots. Each number is the decimal (base-10) representation for an eight-digit
binary (base-2) number, also called an octet. For example: 216.27.61.137, 192.168.1.15
IPv6 uses 128 binary, bits to create a single unique
address on the network. An IPv6 address is expressed by eight groups of
hexadecimal (base-16) numbers separated by colons, as in
2001:cdba:0000:0000:0000:0000:3257:9652. Groups of numbers that contain all
zeros are often omitted to save space, leaving a colon separator to mark the
gap (as in 2001:cdba::3257:9652).
2) Domain
Naming System: DNS is a hierarchical,
distributed method of organizing the name space on Internet. The DNS is a
worldwide system of servers that stores location pointers to Web sites. It
translates Internet domain and host names to IP addresses and vice versa.
DNS implements a distributed
database to store domain names and their web server's IP addresses on the
Internet. The DNS database resides on a hierarchy of special database servers.
Whether you're accessing a
Web site or sending e-mail, your computer uses a DNS server to look up the
domain name you're trying to access. The proper term for this process is DNS
name resolution, and you would say that the DNS server resolves the domain name
to the IP address.
For example, when you enter
"http://www.howstuffworks.com" in your browser, part of the network
connection includes resolving the domain name "howstuffworks.com"
into an IP address, like 70.42.251.42, for HowStuffWorks' Web servers.
3) Messenger: Messenger is an app used for instant messaging to
individuals or groups. It allows to share photos, videos, audio recordings and
other files. Example: Yahoo Messenger, MSN messenger, Facebook messenger, AOL,
gtalk, etc.
4) FTP: The File Transfer Protocol
(FTP) is a standard network protocol used to transfer computer files between a
client and server on a computer network. It can also be used to send
configuration files and software updates for network switches and routers. FTP
uses ports for communications and also uses encryption to protect the
information being received and sent.
6) Gateway
Access: Gateway Access is also known
as Level-One connection. The gateway allows two different types of networks to
communicate with each other. A network gateway can be implemented completely in
software, completely in hardware, or as a combination of both. Depending on the
types of protocols they support, network gateways can operate at any level of
the OSI model. For example within India, all access to Internet from India are
through BSNL gateway.
7) Dial-up
Connection: Dialup
connection is also known as Level Two connection. It provides connection
through a dial-up terminal connection.
It is a form of Internet
access that uses the facilities of the public switched telephone network (PSTN)
to establish a connection to an Internet service provider (ISP) by dialing a
telephone number on a conventional telephone line. The user's computer uses an
attached modem to encode and decode information into and from audio frequency
signals, respectively.
When connecting, the modem
will pick up the phone and dial a number that is attached to Internet Service
Provider's computer(host). After the connection has been made the computer can
check e-mail, browse the Internet, and share files.
It allows users to surf the
Web at 56 Kbps speed. The types of dial-up connection are:
a) Shell Connection b) TCP/IP Connection c) ISDN connection

7) Cell
References – A cell
reference in a formula is the address of a cell, or the addresses of a range of
cells. It tells the program where to look for the values or data to be used in
a formula. There are two types of cell references:
i)
Absolute Reference:
It is the cell address in the formula that is fixed. They do not change if you
copy a formula from one cell to another. It is given by preceding both column
and row number by the dollar sign($). Example- Formula =$A$1*B1, If it is copied down a column it will change
to =$A$1*B2
ii)
Relative Reference:
It automatically changes when the formula is copied to a new location. The
changed cell address will be relative to the address of the cell containing
formula. Example the formula =A1*B1 is copied down a column it will change to
=A2*B2
Answer
the following:
