    Study Notes

    Internet Services

    • The Internet provides directory and database services, Internet white pages, and domain name registration.
    • The World Wide Web Consortium (W3C) was founded in 1994 to develop common protocols for the evolution of the World Wide Web.

    Getting Connected to the Internet

    • The basic requirements for getting connected to the Internet include a computer with at least a 386-microprocessor chip, 16 MB of RAM, a color monitor, and a hard disk with at least 200 MB of free space.
    • A modem is necessary to transmit data over telephone lines, with speeds measured in kilobits per second (Kbps).
    • There are two types of modems: internal modems (fitted inside the computer) and external modems.

    Internet Software

    • Three types of software are required to connect to the Internet: TCP/IP, dialer software, and a web browser.
    • TCP/IP is the basic communication protocol of the Internet, allowing programs on the user's computer to communicate over the Internet.
    • Dialer software instructs the modem to dial the phone number and identify the user's machine to the access provider's system for access to the network.
    • A web browser is essential for viewing information available on the World Wide Web.

    Internet Applications

    • The Internet provides a wide variety of services, including electronic mail, file transfer, vast information resources, interest group membership, interactive collaboration, multimedia displays, real-time broadcasting, and shopping opportunities.
    • Electronic mail (e-mail) is a fast, easy, and inexpensive way of communicating with other Internet users around the world.
    • E-commerce enables the purchase of goods and services online, with developments in software providing increased facilities, such as digital signatures and encryption.

    Electronic Mail

    • Electronic mail (e-mail) allows users to send messages to multiple recipients using Cc (carbon copy) and Bcc (blind carbon copy).
    • Attachments can be sent with e-mails, such as files created with programs like MS Word or Zip files.
    • The electronic mailing system works like the postal service, with mail servers forwarding mail using SMTP (Simple Mail Transfer Protocol) in conjunction with POP (Post Office Protocol) and IMAP (Internet Mail Access Protocol) servers.

    Dynamism on the Web

    • Dynamism on the web is achieved using programming languages such as Perl, JavaScript, VBScript, Active Server Pages, PHP, and eXtensible Markup Language (XML).
    • Scripts are written to provide interaction with web servers, allowing users to interact with web pages.

    Internet and Viruses

    • Viruses are programs or small code segments written with malicious intent, capable of attaching themselves to existing programs or files and replicating without the user's knowledge or permission.
    • Viruses can enter computer systems from external sources like CD, pen drive, or e-mail and execute when an infected program is executed.
    • There are many types of viruses, ranging from slightly irritating to destructive, with various levels of destructiveness.
