How to Study (Category: Education)

Reading (study) is an art. The students are familiar with the art can get high marks with less hardwork. Our often students are not familar with this art so that they work hard but can't get the high marks. If you familar with principles of study, then you can also get high marks without hard work or with less hard work.

While studying important thing is that you have to calm, confident and alert. When you'r calm, the speed of studying increases. Due to mental stress, the concentration is effected and you will not understand anything. It also effects memory and after reading several hours there is no advantage of study. For study please obey the following some peinciples.

It is important to study in good and calm atmosphere so you need to make sure that:

The atomsphere is relaxed. There is no T.V, Radio, Telephone etc . Not often peoples come there. Distruction is too low / Minimize outside interference۔ Place of study like chair is comfortable. There is natural light, if not then use that light wich is like natural light. Fresh air can com easily so you can take long breathings. The best place of study is sitting on the table in the bedroom.

You have to determined the location of study. Place your medals and certificates around you because it helps you to increase your confident. Donot use mobile while studying or make sure to switch off it so no one can disturb you.

Determine the time of the study. Donot do anything in the studytime. Make a timetable for the study so you can easily study the tareted subjects and lessons etc.

SIM Instruction in 8085 microprocessor

What is the function performed by SIM Instruction?

The SIM instruction in the 8085 microprocessor is used to set (SIM) the interrupt mask. With SIM, you can mask or unmask RST5.5, RST6.5, and RST7.5, you can reset the pending RST7.5 flip flop, and you can set or reset the SOD (Serial Output Data) pin.

difference between hardware and software interrupts in 8085 microprocessor

Differentiate between hardware interrupts and software interrupts of 8085.

• The software interrupt is initiated by the main program, but the hardware interrupt is initiated by an external device.
• In 8085, the software interrupt cannot be disabled or masked but the hardware interrupt except TRAP can be disabled or masked.

Project Specifications in Software Engineering

For what purpose Specifications are actually meant?

A specification document describes how something is supposed to be done. This document may be very detailed, defining the minutia of the implementation; for example, a specifications document may list out all of the possible error states for a certain form, along with all of the error messages that should be displayed to the user. Sometimes, when a project doesn't meet its expected result, it may be referred to as being out of specification; the abbreviation OOS may also be used.

Five different specifications a project may have are:

1) Game company's product and game specifications are much more important for determining the quality of the product and their different games.

2) As with all performance measures, a company ensures that specifications are reasonable and measurable.

3) Company conveys financial information concerning desired products from a buyer to a seller.

4) With prescriptive specifications given by company there is little scope for misunderstanding in any dealing.

5) User of their games and buyers of their products have more opportunity to pass risk onto the company organizers, as they have the responsibility for the way the specification is met.
