Environmental pollution
Environmental pollution refers to the presence or introduction of harmful substances or contaminants into the natural environment that cause adverse effects on living organisms, ecosystem, and the nature world. Thank you for reading this post, don't forget to subscribe! Environmental pollution has become a critical problem globally, affecting every aspects of human life, including health, economy and the environment itself. This essay discusses their causes, effects and possible solutions of it. The causes of environment pollution are numerous and varied. One of the main causes is human activities such as industrialization, transportation, and agriculture. Industrialization, for example, involves the large amount of waste and emissions, which are often toxic and harmful to the environment. transport on the other hand, release large amount of carbon dioxide and others pollutants into the air. agriculture, particularly intensive farming, can result in soil erosion, water pollution, and the loss of biodiversity. Another major causes of environmental pollution are natural disasters such as floods, earthquakes and hurricanes. These events can result in the release of hazardous materials and chemicals into the environment, which can have severe impacts on human health and ecosystems. The effects of environmental pollutions ca be severe and long lasting. air pollution, for examples, can cause respiratory problems, heart diseases, and lungs cancers. Water pollution can lead to the contamination of drinking water sources, making them unsafe for human consumptions. soil pollution can affect the fertility of the soil, making it difficult to grow crops. noise pollution can cause hearing loss and other health problems. To address the environment pollution, a range of possible solution exists. One important approach is to reduce the over uses of fossils fuels. Another approach is to improve waste management. government can impose limits on the amount of pollution that industries and other entities are allowed to release into the environment. In conclusion, environmental pollution is a serious and complex issues that requires the concerted efforts of individuals, governments and organizations to address.it is critical that we take action now to protect the environment for future generations.

Microprocessor and Computer Architecture Model Question and Solution(IT-228)
BIM 3rd Semester Thank you for reading this post, don't forget to subscribe! Group “A” 1.Brief Answer Questions: a .What is instruction? Ans: Instruction refers to a set of steps or guidelines given to someone in order to complete a task or achieve a specific goal. Instructions are typically communicated using binary code, a sequence of 0s and 1s that describe the action a computer system is expected to perform. b. What do you mean by memory and data bus? Ans: c. Define SAP1. Ans: It stands for Simple As Possible1. The SAP1 microprocessor is designed to perform basic arithmetic and logic operations, as well as data manipulation tasks. It serves as a starting point for beginners to understand the inner workings of a microprocessor and gain hands-on experience in building and programming a simple computing system. d. What do you mean by operation code? Ans: Operation code, also known as opcode, refers to the specific instructions that a computer processor can execute. These codes are typically represented in binary form and are used to perform various operations within a computer system. e. Define input and output device. Ans: Group” B” Short Answer Questions: 2. Differentiate between RISC and CISC. Ans: The difference between RISC and CISC are as followed: Based-On RISC CISC Differences It stands for Reduced Instruction Set Computer. It stands for Complex Instruction Set Computer. Definition It is a microprocessor architecture that uses small instruction set of uniform length. It refers to hundreds of instructions of different sizes to the users. Price They are inexpensive. They are relatively expensive. Size It has fixed-length encodings for instructions. It has variable-length encodings of instructions. Uses It uses LOAD and STORE that are independent instructions in the register-to-register a program’s interaction. It uses LOAD and STORE that are independent instructions in the register-to-register a program’s interaction. Examples Examples of RISC chips include SPARC, POWER PC. Examples of CISC include Intel architecture, AMD. 3. Explain the shift micro operations with example. Ans: Shift micro-operations are used for serial transfer of data. They are also used in conjunction with arithmetic ,Logic and other data processing operation. Shift micro-operations are used when the data is stored in registers. These micro-operations are used for the serial transmission of data. The contents of a register can be shifted to the left or the right. In shift-right operation, the serial input transfers a bit into the leftmost position. The data transferred by the serial input decides the type of shift. There are three types of Shift Micro-operation and they are: Logic Shift Micro-operation. Logical shift can be defined as the shift of the bits to the right or left serially. This operation is associated with shift of data bits towards left or right and allowing a serial bit stream to occupy vacated bit positions. There are two types of Logic Shift Micro-operation and they are: a. Logic Shift Left (Shl) In this shift one position moves each bit to the left one by one. The empty LSB is filled with 0 and the MSB is rejected.Example: Every time we shift left the bits by 1, it multiples the number two. b. Logic Shift Right (Shr) In this shift one position moves one bit to the right one by one . The LSB is rejected and the empty MSB is filled with 0. Example: Every time we shift right the bits by 1, it divides the number two. Circular Shift Micro-operation. The circular shift also named as rotate shift circulates the bits among the ends of the register without losing information. We can achieve this by connecting the output terminal to the input terminal of the register. The circular shift in the micro operation circulates the bits in the sequence of the register around the both ends. Circular Shift Micro-operation are classified into two groups and they are: a. Circular Shift Left (Cil). Each bit in the register is shifted to the left one by one after shifting the LSB becomes empty, So the value of the MSB is filled in there. Example: b. Circular Shift Right (Cir). Each bit in the register is shifted to the right one by one in this micro operation, after shifting, the most significant bit(MSB) place becomes empty, so it is filled with the value at the LSB. Example: Arithmetic Shift Micro-operation. Arithmetic Shift Micro-operation is as same as Logic Shift Micro- operation .It shift signed binary number to left or right. For these operations proper care must be taken. For shift left the content of the register is multiplied by 2 whereas For shift right the content of the register is divided by 2. The arithmetic shift must leave the sign bit unchanged. Arithmetic Shift is of two types: Arithmetic Left Shift (Ashl) Each bit in the register is shifted to the left one by one in this shift micro-operation. The most significant bit MSB is moved outside the register , and the place of the LSB is filled with 0. Example: Arithmetic Right Shift (Ashr) Each bit in the register is shifted to the right one by one in this shift micro-operation. The MSB is filled with same number as its others and bits are moved towards right and last bit is discarded of LSB. Example: 4. Explain the Control unit and ALU of basic computer. Ans: Control Unit: CU stands for Control Unit. It is one of the fundamental parts of the CPU. The main work of the CU is to tell the most efficient method to work. It guides all the related operations to the individual parts of the processor. Some basic operation performed by it includes taking guidelines, controlling sequential execution, managing information stream in the correct course, directing and observing the time needed amid the preparing and taking care of different functions, etc. It instructs the memory, logic unit, and both output and input devices of the computer on how to respond to the program’s instructions. CPUs and GPUs are examples of devices that use
