. convert the decimal numbers -101 and -67 into hexadecimal number 2. add two hexadecimal numbers (results of the previous question), and answer the followings, a. what is the sum in 8-bits system? answer in hexadecimal. b. in 8-bit system, the answer is not correct. explain why you get incorrect results.
Answers
The correct answer in 8-bit system is 5E, which is obtained by taking the last two digits of the sum (9E) and dropping the carry (1).
To convert decimal numbers -101 and -67 into hexadecimal, we need to first convert them to binary and then group the bits into groups of four to represent each hexadecimal digit.
-101 in binary is 10011011. Grouping this into groups of four, we get 1001 1011. In hexadecimal, this is 9B.
-67 in binary is 10111101. Grouping this into groups of four, we get 1011 1101. In hexadecimal, this is BD.
To add these two hexadecimal numbers, we can use the following steps:
1. Align the two numbers vertically, with the least significant digit (rightmost) aligned.
2. Add the two digits in each column, starting from the right. If the sum is less than 16 (10 in hexadecimal), write the result. Otherwise, subtract 16 (10 in hexadecimal) from the sum and carry 1 to the next column.
3. Continue adding columns until all digits have been added.
9B + BD = 158
In summary, the answer is not correct because 158 in hexadecimal is 9E, which is a 2-digit number and cannot be represented in an 8-bit system. The maximum value that can be represented in 8 bits is FF, which is 255 in decimal.

Answers
An HTML tag is a notation that encloses a name in brackets of angle to indicate a specific piece of information on a Web page. The best choice is therefore option B.
The notation that uses a name in angle brackets to annotate a piece of Web page information is called a tag. A web page is a collection of web resources that are accessed via the internet using a web browser. Web pages may include hypertexts, images, videos, and other multimedia components.Web pages are made up of elements, and HTML is used to create those elements.
Tags are used in HTML to define web page elements such as text, images, and videos. HTML stands for HyperText Markup Language. It is a markup language that is used to structure web content and is often the first language learned by individuals interested in web development.HTML tags are enclosed in angle brackets like these: < >. Tags come in pairs, with the opening tag preceding the content and the closing tag following the content.
The syntax of HTML tags requires that each tag contains an element and one or more attributes. The element defines the type of HTML element, while the attribute is used to modify the behavior of the element. In summary, tags are used in HTML to define web page elements, and they are enclosed in angle brackets. They contain elements and attributes and come in pairs, with the opening tag preceding the content and the closing tag following the content.

Network address translation (NAT) working –
Generally, the border router is configured for NAT i.e the router which have one interface in local (inside) network and one interface in global (outside) network. When a packet traverse outside the local (inside) network, then NAT converts that local (private) IP address to a global (public) IP address. When a packet enters the local network, the global (public) IP address is converted to local (private) IP address.
If NAT run out of addresses, i.e., no address is left in the pool configured then the packets will be dropped and an Internet Control Message Protocol (ICMP) host unreachable packet to the destination is send.

verifying a trigonometric identity icon in exercises 51, 52, 53, and 54, verify the identity.
Answers
To verify trigonometric identities in exercises 51, 52, 53, and 54, a detailed explanation of each identity is required. Since the specific identities are not provided, I will explain the general approach to verifying trigonometric identities.
The process of verifying a trigonometric identity involves manipulating the expressions on both sides of the equation to demonstrate that they are equivalent. This is typically done by simplifying one side of the equation using known trigonometric identities and algebraic manipulations, until it matches the other side of the equation.
The key to successfully verifying trigonometric identities lies in applying fundamental trigonometric identities, such as the Pythagorean identities, reciprocal identities, quotient identities, sum and difference identities, and double-angle identities, among others. These identities allow for the transformation and simplification of trigonometric functions.
In summary, verifying trigonometric identities involves manipulating the expressions on both sides of the equation using known trigonometric identities and algebraic techniques until they are equivalent. This process requires applying the fundamental trigonometric identities and carefully simplifying the expressions step by step.

Assume that you will design a programming language with Dynamic and Flexible Arrays: arrays whose dimensions are not known until storage is allocated for an array, and the size can change (grow/shrink) after that. Briefly explain among static data area, stack and heap, which memory regions are proper for such arrays. Moreover, briefly describe how bounds checking would be supported. You should consider both one- and multi-dimensional arrays
Answers
Dynamic and flexible arrays require a memory region that can handle variable sizes and allow for resizing.
Dynamic and flexible arrays, where the dimensions are unknown until runtime and can change in size, require a memory region that can accommodate this flexibility.
The heap is suitable for such arrays because it allows for dynamic memory allocation and deallocation. Unlike the static data area or stack, the heap provides the ability to allocate memory at runtime and resize arrays as needed.
To support bounds checking, the language can include metadata alongside each array. This metadata would store information such as the current size and capacity of the array.
When accessing elements, the language can check the array indices against the bounds specified in the metadata. If an index exceeds the allocated range, an out-of-bounds error can be raised, preventing access to invalid memory locations and ensuring the integrity of the array.
