Registers, flags, and strings are components that store data temporarily for microprocessor calculations. Registers hold instruction codes, flags store binary values to mark specific data structures that impact processing outcomes, and strings are collections of contiguous memory locations usually storing bytes, words, or double words that microprocessors can manipulate with instructions like MOVE.

1) What is a register? Be precise. Name at least two components in the LMC that meet the
qualications for a register. Name several different kinds of values that a register might hold.
Suppose that the following instructions are found at the given locations in memory:
20
LDA
50
21
ADD
51
50
724
51
006
a. Show the contents of the IR, the PC, the MAR, the MDR, and A at the conclusion of
instruction 20.
b. Show the contents of each register as each step of the fetch–execute cycle is performed for
instruction 21.
3) what is the purpose of the instructions register? What takes the place of the instruction
register in the LMC?
4) What is the explanation for the reasons why programmed IO does not work very well when
the IO device is a hard disk or a graphics display?

1)The Little Man Computer (LMC) is an instructional model of a computer, created by Dr. Stuart
Madnick in 1965.The LMC is generally used to teach students, because it models a simple von
Neumann architecture computer - which has all of the basic features of a modern computer. It
can be programmed in machine code (albeit in decimal rather than binary) or assembly code.
Register:
In a computer, a register is one of a small set of data holding places that are part of a computer
processor . A register may hold a computer instruction , a storage address, or any kind of data
(such as a bit sequence or individual characters). Some instructions specify registers as part of
the instruction. For example, an instruction may specify that the contents of two defined registers
be added together and then placed in a specified register. A register must be large enough to hold
an instruction - for example, in a 32-bit instruction computer, a register must be 32 bits in length.
In some computer designs, there are smaller registers - for example, half-registers - for shorter
instructions. Depending on the processor design and language rules, registers may be numbered
or have arbitrary names.
Small, permanent storage locations within the CPU used for a particular purpose
Manipulated directly by the Control Unit
Wired for specific function
Size in bits or bytes (not in MB like memory)
Can hold data, an address or an instruction
Use of Registers
Scratchpad for currently executing program
Holds data needed quickly or frequently
Stores information about status of CPU and currently executing program
Address of next program instruction
Signals from external devices
General Purpose Registers
User-visible registers
Hold intermediate results or data values, e.g., l.

The College Bus Management system is completely developed by Visual Basic .NET Version. The application is connect with most secured database language MS SQL Server. The application is develop by using best combination of front-end and back-end languages. The application is totally design like flat user interface. This flat user interface is more attractive user interface in 2017. The application is gives more important to the system functionality. The application is to manage the student’s details, driver’s details, bus details, bus route details, bus fees details and more. The application has only one unit for admin. The admin can manage the entire application. The admin can login into the application by using username and password of the admin. The application is develop for big and small colleges. It is more user friendly for non-computer person. Even they can easily learn how to manage the application within hours. The application is more secure by the admin. The system will give an effective output for the VB.Net and SQL Server given as input to the system. The compiled java program given as input to the system, after scanning the program will generate different reports. The application generates the report for users. The admin can view and download the report of the data. The application deliver the excel format reports. Because, excel formatted reports is very easy to understand the income and expense of the college bus. This application is mainly develop for windows operating system users. In 2017, 73% of people enterprises are using windows operating system. So the application will easily install for all the windows operating system users. The application-developed size is very low. The application consumes very low space in disk. Therefore, the user can allocate very minimum local disk space for this application.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

4. A flag is one or more data bits used to store
binary values as specific program structure
indicators.
A computer interprets a flag value in relative
terms or based on the data structure presented
during processing, and uses the flag to mark a
specific data structure. Thus, the flag value
directly impacts the processing outcome.
