what is the minimum number of cycles needed to completely execute n instructions on a cpu with a k stage pipeline? justify your formula.
The minimum number of cycles needed to completely execute n instructions on a cpu with a k stage pipeline is k+(n-1).
What is a pipeline?A pipeline is the mechanism by which a RISC processor executes instructions. By fetching the next instruction while other instructions are decoded and executed, a pipeline speeds up execution. Consider the pipeline to be an automobile assembly line, with each stage performing a specific task in the production of the vehicle.
The circuit is divided into k parts by a K stage pipeline. It is K times faster because each stage has the same transistor delay (ideally). (For example, a conveyor belt system in a car factory)
As we have k stage pipeline. For the first instruction we take k cycles and for the next n-1 instructions we take only n-1 cycles. So the total clock cycles will be k+(n-1).

you are diagnosing a network communication problem on a computer that uses the tcp/ip protocol. what address can you use to test network services without actually accessing the network medium?
127.0.0.1 is the address that we use to test network services without actually accessing the network medium when diagnosing a network communication problem on a computer that uses the tcp/ip protocol.
What is TCP/IP protocol?
TCP/IP specifies how data is transferred from sender to receiver. Application programs first send messages or data streams to one of the Internet Transport Layer Protocols, either the User Datagram Protocol (UDP) or the Transmission Control Protocol (TCP) (TCP).
These protocols receive data from applications, divide it into smaller pieces known as packets, add a destination address, and then forward the packets to the next protocol layer, the Internet Network layer.
The Internet Network layer encloses the packet in an Internet Protocol (IP) datagram, inserts the datagram header and trailer, determines where to send the datagram (directly to a destination or via a gateway), and forwards the datagram to the Network Interface layer.
The Network Interface layer receives IP datagrams and sends them as frames over network hardware such as Ethernet or Token-Ring networks.
