Using exceptions, you can manage errors and bugs and stop programs from crashing.

An object that shows something went wrong is an exception. A way to fix the problem should be offered by the exception object, or at the very least it should explain what went wrong.

Typically, the exception object will include a "stack trace," which aids in retracing your steps through your program to hopefully identify the precise point where something went wrong.

Checked exceptions and runtime exceptions are differentiators in some programming languages, like Java. As checked exceptions are checked at compile time, failing to provide an exception handler or passing the buck will prevent your program from compiling.

The Java program that uses comments to clarify each line is as follows:

import java.util.Scanner;

public class badsubscriptcaught{

  public static void main(String[] args) {

      String[] nameArray = {"Liam", "Olivia" , "Noah", "Emma", "Oliver","Ava","Elijah","Charlotte","Michael","David"};

There are four main types of computer networks: LAN(Local Area Network) (Local Area Network) PAN(Personal Area Network) MAN( Metro Area Network) WAN (Wide Area Network)

A network system performs the crucial task of creating a cohesive architecture that permits data to be transferred between various equipment types in a nearly seamless manner in addition to physically connecting computer and communication devices. The Systems Network Architecture from IBM and the ISO Open Systems Interconnection.

Wide-area networks (WANs) and local area networks (LANs) are the two fundamental types of networks.

A memory address in computing is a reference to a particular memory region that is used at different levels by hardware and software. Memory addresses are unsigned numbers that are often presented and handled as fixed-length digit sequences. Such a numerical semantic is based on CPU features (such as the instruction pointer and incremental address registers) as well as on the use of memory in the manner of an array that is supported by different programming languages. The main memory of a digital computer is made up of numerous memory regions. There is a physical address, which is a code, for every memory region.

(a) Number of blocks in main memory is 3.

(b) The memory address has 24 bits, the cache has 128 blocks, and each block contains 64 bytes

(c) The memory address 0x01D872 maps to cache block 135.

To determine the number of blocks of main memory in a computer with 224 bytes of byte-addressable main memory and a cache of 128 blocks, each containing 64 bytes, we can use the following equation: number of blocks = memory size / block size.

In this case, the memory size is 224 bytes, and the block size is 64 bytes, so the number of blocks is 224 / 64 = 3.5. Since we cannot have a fractional number of blocks, the actual number of blocks in main memory is 3.

The format of a memory address as seen by the cache depends on the number of bits in the address, the size of the cache, and the size of the blocks in the cache. In this case, the memory address has 24 bits, the cache has 128 blocks, and each block contains 64 bytes,

In this format, the tag field contains 11 bits, the index field contains 7 bits, and the offset field contains 6 bits. The tag field stores the address of the block in main memory, the index field stores the address of the block in the cache, and the offset field stores the address of the byte within the block.

To determine which cache block the memory address 0x01D872 maps to, we need to first convert the hexadecimal address to binary and then extract the index and offset fields from the address.

The hexadecimal address 0x01D872 is equivalent to the binary address 0001 1101 1000 0111 0010. This address has 24 bits, so we can split it into the tag, index, and offset fields

The index field contains 7 bits, and the binary value of this field is

1000 0111, which is equivalent to the decimal value 135. Therefore, the memory address 0x01D872 maps to cache block 135.
