Key Points

  • Email, short for "electronic mail," is one of the most widely used features of the Internet, along with the web. It allows you to send and receive messages to and from anyone with an email address, anywhere in the world.

Additional Information

  • Email uses multiple protocols within the TCP/IP suite. For example, SMTP is used to send messages, while the POP or IMAP protocols are used to retrieve messages from a mail server. When you configure an email account, you must define your email address, password, and the mail servers used to send and receive messages. Fortunately, most webmail services configure your account automatically, so you only need to enter your email address and password. However, if you use an email client like Microsoft Outlook or Apple Mail, you may need to manually configure each account. Besides the email address and password, you may also have to enter the incoming and outgoing mail servers and enter the correct port numbers for each one.
  • The original email standard only supported plain text messages. Eventually, email evolved to support rich text with custom formatting. Today, email supports HTML, which allows emails to be formatted the same way as websites. HTML email messages can include images, links, and CSS layouts. You can also send files or "email attachments" along with messages. Most mail servers allow you to send multiple attachments with each message, but they limit the total size. In the early days of email, attachments were typically limited to one megabyte, but now many mail servers support email attachments that are 20 megabytes in size or more.

  1. AOption (a)

    Network Basic Input / Output System 

  2. BOption (b)

    Network Based Input / Output System

  3. COption (c)

    Networking Binary Input / Output System

  4. DOption (d)

    Net Binary In / Out System

View answer & explanation

Correct answer

Answer: (a)A.

Network Basic Input / Output System 

Why this answer is correct

The correct answer is NetBIOS.

Key Points

  • NetBIOS, an acronym for Network Basic Input/Output System, is a suite of protocols that enables applications on different computers within a local area network (LAN) to communicate with each other.
  • Developed in the 1980s, NetBIOS primarily serves as an application programming interface (API), providing a set of functions that applications can use to access network services.

Additional Information

  • Name Resolution: NetBIOS allows applications to locate other devices on the network using unique names instead of complex network addresses.
  • This simplifies communication between devices.
  • Session Management: NetBIOS facilitates the establishment, maintenance, and termination of communication sessions between devices. A session provides a reliable channel for data exchange between applications.
  • Data Exchange: Once a session is established, NetBIOS enables applications to exchange data with other applications on the network. This data can include files, messages, and other types of information.
  • While NetBIOS was originally developed for use on IBM PC networks, it has since been adapted to work with various operating systems and network technologies. It is particularly well-suited for smaller networks where simplicity and ease of use are paramount.
  • However, NetBIOS has certain limitations, such as its lack of support for large-scale networks and its reliance on older protocols. As a result, newer technologies like TCP/IP and DNS have largely superseded NetBIOS in modern networking environments.
  • Despite its limitations, NetBIOS remains relevant in some legacy systems and niche applications. It continues to provide a basic framework for communication within small, localized networks, especially where compatibility with older systems is a concern.

Correct answer

Answer: (a)A.

Both absolute reference and mixed reference

Why this answer is correct

The correct answer is Both absolute reference and mixed reference.

Key Points

  • Dollar ($) sign: In Excel, the dollar sign is used to create absolute references. For example, if you want to refer to cell A1 in a formula and you don't want that reference to change when you copy the formula to another cell, you would use $A$1. However, the dollar sign doesn't signal the start of a formula.

 Additional Information

  • Equal (=): This is the correct symbol to start a formula in an Excel cell.
  • Any calculation or formula in Excel begins with this equal sign. For example, =A1+10 would add 10 to the value in cell A1.
  • Ampersand (&): The ampersand is not used to start a formula in Excel, but rather within formulas to concatenate (link together) different text strings or cell values. For example, the formula =A1&B1 would join together the contents of cells A1 and B1.
  • Percent (%): In Excel, a percent sign is neither used to start a formula nor within a formula typically. It's usually used to represent percentage values. While you can include this in a formula (e.g. =A1*20% to get 20% of the value in A1), it's not used to initiate a formula$.
