Zenmap is the graphical User Interface representation for NMAP Security Scanner. It is an open-source program designed to make NMAP easy for starters to use. Typically, it is used to collect and identify a list of hosts, OS, as well what services are running on them by using a port scanning tool. It is used specifically for the scanning and vulnerability phase of ethical hacking.

A network administrator who wishes to audit all the devices on a specific IP scheme in a network can use NMAP. The admin can go ahead and scan the ports to know exactly which ports are closed and which are opened.

Find the double word-length 2's complement representation of each of the following decimal numbers:a. 3874
miss Akunina [59]

Answer:

-3874₁₀ = 1111 1111 1111 1111 1111 1111 1101 1110₂

Explanation:

2's complement is a way for us to represent negative numbers in binary.

To get 2's complement:

1. Invert all the bits

2. Add 1 to the inverted bits

Summary: 2's complement = -N = ~N + 1

1. Inverting the number

3874₁₀ = 1111 0010 0010₂

~3874₁₀ = 0000 1101 1101₂

2. Add 1 to your inverted bits

~3874₁₀ + 1 = 0000 1101 1101₂ + 1

= 0000 1101 1110₂

You can pad the most signigicant bits with 1's if you're planning on using more bits.

so,

12 bits                          16 bits

0000 1101 1110₂  = 1111 0000 1101 1110₂

They asked for double word-length (a fancy term for 32-bits), so pad the left-most side with 1s' until you get a total of 32 bits.

           32 bits

= 1111 1111 1111 1111 1111 1111 1101 1110

Dmitry [639]

Answer:

c. mentorship programs taking place via the internet

Explanation:

Web 2.0 can be defined as a collection of internet software programs or applications which avails the end users the ability or opportunity to share files and resources, as well as enhance collaboration over the internet.

Basically, it's an evolution from a static worldwide web to a dynamic web that enhanced social media. Some of the examples of social media platforms (web 2.0) are You-Tube, Flickr, Go-ogle maps, Go-ogle docs, Face-book, Twit-ter, Insta-gram etc.

Some of the main characteristics of Web 2.0 are;

I. Social networking.

II. Blogging.

III. Interactive comments being available on many websites.

Also, most software applications developed for Web 2.0 avails its users the ability to synchronize with handheld or mobile devices such as smartphones.

However, mentorship programs taking place via the internet is not a characteristic of Web 2.0 but that of Web 3.0 (e-mentoring).
