When should you not get a patent?
You should not get a patent if you do not have an invention that is eligible for a patent. This means that the invention must be new and non-obvious and must be able to be produced or used in some type of industry. Additionally, a patent can be expensive and time-consuming to obtain, so you may want to consider other forms of protection such as trade secrets or copyrights before investing in a patent.
1. If your invention is not novel, meaning it has already been invented or is obvious to someone with ordinary skill in that area, then you should not get a patent. For example, if you invent a new type of chair but someone has already invented a similar chair, then getting a patent would be fruitless.
2. If your invention does not meet the criteria of patentability, such as it is not useful, novel, or non-obvious, then you should not get a patent. For example, if your invention is something that does not have a practical purpose, like a perpetual motion machine, then it would not meet the criteria for patentability and you should not get a patent.
3. If the cost of getting a patent is higher than the potential value of the invention, then you should not get a patent. For example, if you invent a new type of mousetrap but the cost of patenting it is very high, then you would be better off not getting a patent.
4. If the invention is not patentable subject matter, then you should not get a patent. For example, if you invent a new type of business model, then it would not be patentable subject
The first person to invent a claimed invention—even if a later inventor beats the first inventor to the patent office.A patent is an exclusive right granted for an invention, which is a product or a process that provides, in general, a new way of doing something, or offers a new technical solution to a problem. To get a patent, technical information about the invention must be disclosed to the public in a patent application.

Identification of the network interface and location addressing are the two primary purposes of an IP address.
A 32-bit number is what the Internet Protocol Version 4 (IPv4) characterises as an IP address. However, a latest version of IP (IPv6), utilising 128 bits for such IP address, was standardised in 1998 in response to the expansion of the Internet and the exhaustion of IPv4 addresses. Deployment of IPv6 has been ongoing that since middle of the 2000s.

risc architectures generally have fewer, simpler instructions that run faster than cisc instruction. group of answer choices true false
Yes, it's true, RISC architectures generally have fewer, simpler instructions that run faster than CISC instructions Due to their streamlined instruction set, RISC computers frequently perform two to four times better than CISC processors.
Also due to a smaller instruction set, this design requires less chip area. Although CISC uses less memory and a compiler, the more complicated hardware needed to implement the complex instructions makes it more expensive. The processor's instruction set is condensed in RISC architecture to speed up execution. It uses a limited number of highly optimized instructions, most of which are register-to-register operations. A reduced number of instructions is used, which speeds up the execution.
This executes any instruction using the pipeline mechanism. The fetch, decode, and execute steps of instruction can all be completed by the processor at once thanks to the pipelining technique. The graphic below demonstrates how to use the pipelining approach as instructed.
