SOFTWARE PROCESS & SOFTWARE PROCESS ACTIVITIES
A Software Process is a set of activities and associated results that produce a software product.
Characteristics of software process
- Understandability
- Visibility
- Supportability
- Acceptability
- Reliability
- Maintainability
- Rapidity
SOFTWARE ENGINEERING
The systematic approach to the development, operation and maintenance of a software product is called as Software Engineering
COMPONENTS OF SOFTWARE ENGINEERING
SDLC : Software Development Life cycle
SQA : Software Quality Assurance
SPM : Software Product Management
SM : Software Management
CASE : Computer Aided Software Engineering
SOFTWARE & ITS CLASSIFICATION
A software is a collection of computer programs , procedures, rules and associated documentation and data.
CLASSIFICATION OF SOFTWARE
System Software
•Operating Software
•Assembler
•DebuggeR
Application Software
•Image Processors
•Database
•Games
CHARACTERISTICS OF SOFTWARE
Maintainability
Software must be written in such a way that it may evolve to meet the changing needs of customers.
Dependability
It has a range of characteristics,, including reliability, security and safety. Dependable software should not cause any physical or economic damage in the event of system failure.
Efficiency
It includes responsiveness, processing time, memory utilization, etc.
Usability
It should have an appropriate user interface and adequate documentation.
Intangible
The product cannot be touched to get an idea of its quality.
ADDING A TABLE TO DATABASE - RETRIEVE IT ON DATA GRID CONTROL I am using the programming language C#. net and SQL Server 2012 in Visual studio 2013.
I am using the programming language C#. net and SQL Server 2012 in Visual studio 2013.
This video tutorial illustrates the following :
- how to create a new project (C# Desktop Application )
- how to create a database using Visual Studio Designer
- How to add a table to the database
- How to retrieve the stored data to a datagrid control on the form
This tutorial is appropriate for the beginners' level .

OBJECTVES OF OPERATING SYSTEMS
Objectives of an operating system is :
- to control and coordinate the use of system resources like CPU time, IO devices, memory
- to provide a convenient environment for the user to access the available resources.
- to increase the productivity of processing resources
- to use the computer hardware efficiently

STRESS MANAGEMENT - 01
What is Stress?
Stress can be defined as a response of the body to any demand placed on it.
Stress can be influenced by both internal and external factors.
external demands can be temperature change in the environment,etc.
internal demands can be biological demand like illness, psychological demands like fear, etc.
Based on an individual's perception of a specific situation and his ability to cope with it, stress level and the way they react varies from person to person.

OPERATING SYSTEMS - INTRODUCTION
What is an Operating System?
An Operating System is a software application which acts as an interface between the user and the system hardware.
It controls and coordinate the processes, peripheral devices and memory allocation among the processes.

INSTRUCTION WORD SIZE
- 8085 is an 8-bit microprocessor.
- It can handle 8-bits at a time.
- The memory location of 8085 microprocessor can accommodate 8-bits of data.
- To store 16-bits data, they are stored in two consecutive memory locations.
- The word length of an instruction can be :
- 1 byte / 1 word
- 2 bytes / 2 words
- 3 bytes / 3 words
1 - Byte Instructions
- They include opcode and operands in the same byte.
- Operands are internal registers and coded into the instruction.
- Instructions require one memory location to store single byte in the memory.
2 - Byte Instructions
- 1st byte specifies opcode and 2nd byte specifies operand.
- Instructions require two memory locations to store in the memory.
3 - Byte Instructions
- 1st byte specifies opcode and 2nd & 3rd bytes specifies 16-bit address
- 2nd byte holds the low order address.
- 3rd byte hods the high order address.
- Instructions require three memory locations to store single byte in the memory.

INSTRUCTION FORMAT
- Each instruction has two parts :
- Opcode
- Operand
- Opcode is the code for the operation to be performed.
- It is also known as Machine Code.
- Operand is the data to be operated.
- Operand can be specified as :
- 8-bit data
- internal registers
- memory location
- 8-bit / 16-bit address
INSTRUCTION
- An instruction is a binary pattern designed inside the microprocessor to perform a specific function.
- In other words, it is actually a command to the microprocessor to perform a given task on specified data.
- An instruction set of microprocessor is a collection of instructions designed to perform specified operations on given data.
- It determines what functions the microprocessor can perform.
