Features of 8086 Microprocessor As discussed in the previous chapters, the 8085 microprocessor is an 8-bit microprocessor. It  was generally used in small-scale industrial applications to control few operations. The limitations  of the 8085 microprocessor are as follows. (1) Low speed of execution. (ii) Low memory addressing capability. (ii) A limited number of general purpose registers. (iv) Less powerful instruction set. A 16-bit microprocessor 8086 was introduced by lntel in 1978.  The 8086 microprocessor has many powerful and high-speed computational resources, The 8086  the microprocessor also has a much powerful instruction set along with the architectural developments.  This provides a programming flexibility and improvement in speed. The 8086 microprocessor has 16-bit data bus. It can read data from or write data to me and V'O ports either 16-bit or 8-bits at a time. The 8086 microprocessor has 20-bit address bus. It can address any one of 20 (1.048,576) memory locations. E

Objects are the basic runtime entities or basic unit of an object-oriented system. Object are treated as real-world entities which can be sensed in order to understand it properly identify anything of this world try to extract the various property of it, various mode of its interaction on combining all these values what we have created is an object. Object are identified by their unique name. an object represents a particular instance of a class. There can be more than one instance of an object. Each instance of an object can hold its own relevant data. The object may represent a person, a place, a bank account, or any item that the program has to handle. They may also represent user-defined data such as vector, time and lists Programming problem is analyzed in term of the object and the nature of communication between them. Object take up a space associated address like a structure in c.

Utilizing a DBMS to store and oversee information accompanies preferences, yet additionally overhead. One of the greatest focal points of utilizing a DBMS is that it lets end clients and application developers access and utilize similar information while overseeing information respectability. Information is better secured and kept up when it can be shared utilizing a DBMS as opposed to making new cycles of similar information put away in new documents for each new application. The DBMS gives a focal store of information that can be gotten to by numerous clients in a controlled way.  Focal capacity and management of information inside the DBMS give:  Information reflection and freedom  Information security  A locking system for simultaneous access  A productive handler to adjust the necessities of numerous applications utilizing similar information  The capacity to quickly recuperate from accidents and mistakes, including restartability and recoverability  Strong information respectab

What is database management system A database management system (DBMS) is system programming for making and overseeing databases. The DBMS gives clients and software engineers a systematic method to make, recover, refresh and oversee information. A DBMS makes it workable for end clients to make, read, refresh and erase information in a database. The DBMS basically fills in as an interface between the database and end clients or application programs, guaranteeing that information is reliably sorted out and remains effectively open. The DBMS oversees three vital things: the information, the database motor that enables information to be gotten to, bolted and changed - and the database construction, which characterizes the database's coherent structure.  These three primary components help give simultaneousness, security, information respectability and uniform organization techniques. Run of the mill database organization errands bolstered by the DBMS incorporate change management, exe
