Explanation:

To solve this question, the user needs to know the difference between WAN and LAN technologies.

A Local Area Network (LAN) is a network that is confined to a small geographic area, such as a single building or a campus. LANs are typically used for connecting computers, printers, and other devices together in an office or home environment. LANs typically use Ethernet or Wi-Fi technology to connect devices together.

A Wide Area Network (WAN), on the other hand, covers a much larger geographic area, such as a city, region, or even a country. WANs are used to connect LANs together over longer distances, and they typically use technologies such as leased lines, satellite links, or microwave links.

Now, let's go through each option and explain why it is right or wrong:

A. True: This option is incorrect. While LAN and WAN are both types of computer networks, they require different technologies to operate. For example, LANs often use Ethernet or Wi-Fi technology, while WANs may use leased lines, satellite links, or microwave links. In addition, WANs often require specialized hardware and software to ensure that data is transmitted quickly and securely over long distances.

B. False: This option is correct. LAN and WAN are both types of computer networks, but they require different technologies to operate. LANs are typically confined to a small geographic area and use Ethernet or Wi-Fi technology, while WANs cover a much larger area and use technologies such as leased lines, satellite links, or microwave links.

  1. BER

  2. VB

  3. C++

  4. ASN.1


Correct Option: D
  1. True

  2. False


Correct Option: A
Explanation:

To solve this question, the user needs to know the concept of binary number representation and the parity of numbers.

In binary number representation, each digit can only be 0 or 1. The rightmost digit represents $2^0 = 1$, the second rightmost digit represents $2^1 = 2$, the third rightmost digit represents $2^2 = 4$, and so on. To get the decimal equivalent of a binary number, we add up the values of the digits that have a value of 1.

For the binary number 10111001, the decimal equivalent is:

$1\times2^7 + 0\times2^6 + 1\times2^5 + 1\times2^4 + 1\times2^3 + 0\times2^2 + 0\times2^1 + 1\times2^0$

$= 128 + 0 + 32 + 16 + 8 + 0 + 0 + 1$

$= 185$

To determine if 185 is an odd number, we can check if it is divisible by 2. If it is not divisible by 2, then it is an odd number.

185 is not divisible by 2, therefore it is an odd number.

The Answer is: A
