Total number of subnets: Using the subnet mask 255.255. 255.248, number value 248 (11111000) indicates that 5 bits are used to identify the subnet. To find the total number of subnets available simply raise 2 to the power of 5 (2^5) and you will find that the result is 32 subnets.
Q. How does a microprocessor differentiate data and instruction code?
How does the microprocessor differentiate between data and instruction? When the first m/c code of an instruction is fetched and decoded in the instruction register, the microprocessor recognizes the number of bytes required to fetch the entire instruction.
Q. What does and opcode do?
The opcode tells the processor the job that needs to be done. A simple operation might be ‘add’ or ‘subtract’. Each opcode instruction is very limited in what it can tell the processor to do. A CPU’s instruction set contains the opcodes that it will accept.
Q. What is meant by subnetting?
Subnetting is the technique for logically partitioning a single physical network into multiple smaller sub-networks or subnets. Subnetting enables an organization to conceal network complexity and reduce network traffic by adding subnets without a new network number.
Q. What is subnetting and its advantages?
Subnetting is the practice of dividing up a network into two or more networks. Common advantages of subnetting include enhancing routing efficiency, network management control, and improving network security.
Q. How many types of subnets are there?
There are two types of subnetting: static and variable length. Variable length is the more flexible of the two. Which type of subnetting is available depends upon the routing protocol being used; native IP routing supports only static subnetting, as does the widely used RIP protocol.
Q. What is IP Address Class?
Designing Your IP Addressing Scheme
| Class | Range | Network Address |
|---|---|---|
| A | 0-127 | xxx |
| B | 128-191 | xxx . xxx |
| C | 192-223 | xxx . xxx . xxx |
Q. How do subnets work?
Subnetting works by applying the concept of extended network addresses to individual computer (and another network device) addresses. An extended network address includes both a network address and additional bits that represent the subnet number.
Q. What is subnetting formula?
To calculate the number of possible subnets, use the formula 2n, where n equals the number of host bits borrowed. For example, if three host bits are borrowed, then n=3. 23 = 8, so eight subnets are possible if three host bits are borrowed.
