Answer:
CIDR is based on a variable-length subnet masking technique, which allows a new method of representation for IP addresses. Routing prefix is written with a suffix number of bits of the name, such as 123.0.0.0/8, as the CIDR network has the smallest possible amount of hosts.
Explanation:
CIDR ( Class Inter-Domain Routing ) It is a method that is allocating IP addresses and routing the IP. CIDR is introduced in 1933 and replace the architecture of network design on the internet. CIDR slows down the growth of the routing across the web and helps to slow the IP addresses such as IPv4 addresses.
CIDR consists of two groups of bits in the address. In the new age, the network prefix identifies the whole network. This is used as the basis of routing between IP networks and allocation policies.
IPv4 in-network prefix is 8-bit groups.
A typical IPv4 address is 192.168.0.5 the lowest value is 0, and the highest value is 255
In the given choices, 123.0.0.0 / 8 of the possible smallest number of hosts.
Answer:
Data Confidentiality
Explanation:
A Man-In-The-Middle-Attack (MITM) is an attack when a hacker gets between a communicative situation and digitally eavesdrops.
Answer:
Program
Explanation:
Program is like a set of instructions that helps hardware process data into information.
Every hardware needs a program to process data into information.
For example take the example of a data processing software like MS Excel.
You open a spreadsheet and enter some data into your sheet. and then ask the program to do some calculations with this data and give you output results. The spreadsheet software does this processing in the background for you and provides you the results.
Without program a hardware doesn't know what to do with the data. Therefore, a program is like a instruction set that guides the hardware what to do with the data.
Note: The terms software and program are usually used together but there is a difference between software and program
A software is a generalized term and program is more like a specific term.
software can be made up of several different programs which performs many different tasks. On the other hand, a program only carry out a specific task or set of instructions.
