UNIT I
Generation of Computer Languages
• The first generation languages, or 1GL, are low-level languages that
are machine language.
• The second-generation languages, or 2GL, are also low-level assembly
languages. They are sometimes used in kernels and hardware drives,
but more commonly used for video editing and video games.
• The third-generation languages, or 3GL, are high-level languages, such
as C, C++, Java, JavaScript, and Visual Basic.
• The fourth-generation languages, or 4GL, are languages that consist
of statements similar to statements in a human language. Fourth
generation languages are commonly used in database programming
and scripts examples include Perl, PHP, Python, Ruby, and SQL.
• The fifth-generation languages, or 5GL, are programming languages
that contain visual tools to help develop a program. Examples of fifth
generation languages include Mercury, OPS5, and Prolog.
Internet Concepts
• What is Internet?
• The Internet is essentially a global network of computing resources.
You can think of the Internet as a physical collection of routers and
circuits as a set of shared resources.
• Some common definitions given in the past include −
• A network of networks based on the TCP/IP communications protocol.
• A community of people who use and develop those networks.
Internet-Based Services
Some of the basic services available to Internet users are −
• Email − A fast, easy, and inexpensive way to communicate with other
Internet users around the world.
• Telnet − Allows a user to log into a remote computer as though it were a
local system.
• FTP − Allows a user to transfer virtually every kind of file that can be
stored on a computer from one Internet-connected computer to another.
• UseNet news − A distributed bulletin board that offers a combination
news and discussion service on thousands of topics.
• World Wide Web (WWW) − A hypertext interface to Internet information
resources.
What is WWW?
• WWW stands for World Wide Web. A technical definition of the World Wide
Web is − All the resources and users on the Internet that are using the
Hypertext Transfer Protocol (HTTP).
• A broader definition comes from the organization that Web inventor Tim
Berners-Lee helped found, the World Wide Web Consortium (W3C): The
World Wide Web is the universe of network-accessible information, an
embodiment of human knowledge.
• In simple terms, The World Wide Web is a way of exchanging information
between computers on the Internet, tying them together into a vast
collection of interactive multimedia resources.
What is HTTP?
• HTTP stands for Hypertext Transfer Protocol. This is the protocol being
used to transfer hypertext documents that makes the World Wide
Web possible.
• A standard web address such as Yahoo.com is called a URL and here
the prefix http indicates its protocol
What is URL?
• URL stands for Uniform Resource Locator, and is used to specify addresses on the World
Wide Web. A URL is the fundamental network identification for any resource connected to
the web (e.g., hypertext pages, images, and sound files).
A URL will have the following format −
protocol://hostname/other_information
The protocol specifies how information is transferred from a link. The protocol used for web
resources is HyperText Transfer Protocol (HTTP). Other protocols compatible with most web
browsers include FTP, telnet, newsgroups, and Gopher.
The protocol is followed by a colon, two slashes, and then the domain name. The domain
name is the computer on which the resource is located.
Links to particular files or subdirectories may be further specified after the domain name. The
directory names are separated by single forward slashes.
Hardware and Software Requirements for
Internet connection:
• Connecting a computer using Wireless Broadband
• Connecting a computer using an Ethernet Cable
• Connecting a Computer Using Dial-Up Community
Hardware Requirement :
To connect the Internet, any one of the following is mandatory.

Transfer Protocol), HTTP (Hyper Text Transfer Protocol) and HTTPS
(Hyper Text Transfer Protocol Secured) protocols.
• Browsers and other Internet clients access to the web applications
such as Outlook, Gmail, Whatsapp, Facebook, Twitter and etc.
Types of Internet Connections
• Dial-up Connection :
• A dial-up connection is established when two or more data communication devices use a Public
Switched Telephone Network (PSTN) to connect to an Internet Service Provider (ISP) from
computers. Many remote locations depend on Internet dial-up connections because broadband
and cable are rare in remote areas with low population. Internet Service Providers often provide
dial-up connections, a feasible alternative for budget-conscious subscribers.
Types of Internet Connections
• ISDN
• ISDN is the acronym of Integrated Services Digital Network. It establishes the connection using the phone
lines (PSTN) which carry digital signals instead of analog signals. It is a set of communication standards for
simultaneous digital transmission of data, voice, video, and other services over the traditional circuits of the
public switched telephone network. There are two techniques to deliver ISDN services such as Basic Rate
Interface (BRI) and Primary Rate Interface (PRI).
Types of Internet Connections
• DSL:
• Digital Subscriber Line (DSL) is a high-speed Internet service for homes and
businesses that competes with cable and other forms of broadband Internet. DSL
provides high-speed networking over ordinary Telephone lines using broadband
modem technology. The technology behind DSL enables Internet and telephone
service to work over the same phone line without requiring customers to
disconnect either their Voice or Internet connections.
Types of Internet Connections
• Cable TV Internet Connection (setup box):
• The cable TV network can be used for connecting a computer or a local network to the Internet,
competing directly with DSL (Digital Subscriber Line) technology.
• This type of network is classified as HFC (Hybrid Fiber-Coaxial), as it uses both fiber optics and
coaxial cables. The connection between the cable TV company to the distribution points (Optical
nodes) is made using fiber optics, with distances up to 25 miles (40 km). Each optical node is
typically serves between 500 and 2,000 clients (customers).
Types of Internet Connections
• Satellite Internet Connection:
• Satellite Internet access is Internet access provided through satellite
communication for domestic and enterprise usage. The facility of modern
consumer grade satellite Internet service is typically provided to individual users
through geostationary satellites . It provides fairly high data speeds, along with
latest satellites using Ka-band to attain downstream data speeds up to 50 Mbps
internet speed.
Types of Internet Connections
• Wireless Internet Connection:
• It is a technology for wireless local area networking with devices based on the
IEEE 802.11 standards. Devices that can use Wi-Fi technology include personal
computers, video-game consoles, phones and tablets, digital cameras, smart TVs,
digital audio players and modern printers. Wi-Fi compatible devices can connect
to the Internet via a WLAN and a wireless access point. Such an access point (or
hotspot) has a range of about 20 meters (66 feet) indoors and a greater range of
outdoors. Hotspot coverage can be as small as a single room with walls that block
radio waves, or as large as many square kilometres achieved by using multiple
overlapping access points.
