Q.No.1 

Types of Computers

There are different types of computer systems nowadays for different purpose according to the user needs. However we can classify them into different groups based on different aspects:

Based on Size

We can find four different type of computers based on size.

Super Computers

These are large computers that are most powerful. They can complete tasks very soon and are optimized to complete given tasks quickly.

Mainframe Computers

These are the largest computers and can support hundreds of users simultaneously. These are powerful computers and optimized to run maximum number of applications at one time.

Mini Computers

These are medium sized computers –smaller than mainframe but much larger than personal computers. They can be the best solution for medium scale organizations.

Micro Computers

Micro computers are the smallest when size is concerned. They range from Desktop, Laptop up to the palm top and even smaller ones. Because micro computers are developed to support single person, they are often called personal computers (PCs).

TYPES OF ATTRIBUTES IN DBMS

TYPES OF ATTRIBUTES AND KEYS  IN DBMS

Types of Attributes

• Simple attribute − Simple attributes are atomic values, which cannot be divided further. For example, a student's phone number is an atomic value of 10 digits.
• 
  
• Composite attribute − Composite attributes are made of more than one simple attribute. For example, a student's complete name may have first_name and last_name.
• 
  
• Derived attribute − Derived attributes are the attributes that do not exist in the physical database, but their values are derived from other attributes present in the database. For example, average_salary in a department should not be saved directly in the database, instead it can be derived. For another example, age can be derived from data_of_birth.
• 
  
• Single-value attribute − Single-value attributes contain single value. For example − Social_Security_Number.
• 
  
• Multi-value attribute − Multi-value attributes may contain more than one values. For example, a person can have more than one phone number, email_address, etc.
• 
  
• TYPES OF KEYS
• The different types of keys in DBMS are:
  1. Candidate Key - The candidate keys in a table are defined as the set of keys that is minimal and can uniquely identify any data row in the table.A minimal super key is called a candidate key. An entity set may have more than one candidate key
  2. Primary Key - The primary key is selected from one of the candidate keys and becomes the identifying key of a table. It can uniquely identify any data row of the table.A primary key is one of the candidate keys chosen by the database designer to uniquely identify the entity
  3. Super Key - Super Key is the superset of primary key.A set of attributes (one or more) that collectively identifies an entity in an entity set. The super key contains a set of attributes, including the primary key, which can uniquely identify any data row in the table.
  4. Composite Key - If any single attribute of a table is not capable of being the key i.e it cannot identify a row uniquely, then we combine two or more attributes to form a key. This is known as a composite key.
  5. Secondary Key - Only one of the candidate keys is selected as the primary key. The rest of them are known as secondary keys.
  6. Foreign Key - A foreign key is an attribute value in a table that acts as the primary key in another another. Hence, the foreign key is useful in linking together two tables. Data should be entered in the foreign key column with great care, as wrongly entered data can invalidate the relationship between the two tables

Question on DBMS

 Information in a bank is about customers and their accounts. Customer has a name, address, which
 consists of house number, area, city and one phone number. Account has numbers, type, and balance. 

We need to record customers who own an account. Account can be held individually or jointly. Account cannot exist without a customer. Arrive at an E-R diagram, clearly indicate: entities, attributes, relationships.

MERITS AND DEMERTS OF INDEXNG

MERITS

1)Speed up SELECT query

2)Helps to make a row unique or without duplicates(primary,unique) 

3)If index is set to fill-text index, then we can search against large string values. for example to find a word from a sentence etc.

4)They result  in better queries performance.

5)They make it possible to quickly retrieve (fetch) data.

6)They can be used for sorting..

7)Unique indexes guarantee uniquely identifiable records in the database.

DEMERTS

1)Indexes take additional disk space.

2)indexes slow down INSERT,UPDATE and DELETE, but will speed up UPDATE if the WHERE condition has an indexed field.  INSERT, UPDATE and DELETE becomes slower because on each operation the indexes must also be updated.

3)Some databases will monocase(It means that filenames are case-insensitive) values in fields that are indexed

INDEXES IN DATABASE

In database systems, an index (IDX) is a data structure defined on columns in a database table to significantly speed up data retrieval operations. An index is a small copy of a database table sorted by key values. Without an index, query languages like SQL may have to scan the entire table from top to bottom to choose relevant rows.

TYPES OF INDEX

• 1 Clustered Indexes: Clustered indexes store row data in order. Only a single clustered index can be created on a database table. This works efficiently only if data is sorted in increasing and decreasing order or a limit is specified on the columns involved in the table. Such a sequential arrangement of data on disks reduces block reads.

• 2 Non-Clustered Indexes: In non-clustered indexes, data is arranged in a random way, but a logical ordering is internally specified by the index. Thus, the index order is not the same as the physical ordering of data. A "create index" statement creates a non-clustered index by default, which also creates a clustered index on the primary key. The index keys are sorted here with the leaf containing a pointer to the page. Non-clustered indexes work well with tables where data is modified frequently and the index is created on columns used in order by WHERE and JOIN statements

      3  Dense Index

In dense index, there is an index record for every search key value in the database. This makes searching faster but requires more space to store index records itself. Index records contain search key value and a pointer to the actual record on the disk.

 4         Sparse Index

In sparse index, index records are not created for every search key. An index record here contains a search key and an actual pointer to the data on the disk. To search a record, we first proceed by index record and reach at the actual location of the data. If the data we are looking for is not where we directly reach by following the index, then the system starts sequential search until the desired data is found.

Indexes and Constraints

Indexes are automatically created when PRIMARY KEY and UNIQUE constraints are defined on table columns. For example, when you create a table and identify a particular column to be the primary key, the Database Engine automatically creates a PRIMARY KEY constraint and index on that column.

How Indexes are used by the Query Optimizer

Well-designed indexes can reduce disk I/O operations and consume fewer system resources therefore improving query performance. Indexes can be helpful for a variety of queries that contain SELECT, UPDATE, DELETE, or MERGE statements. Consider the query SELECT Title, HireDate FROM HumanResources.Employee WHERE EmployeeID = 250 in theAdventureWorks2012 database. When this query is executed, the query optimizer evaluates each available method for retrieving the data and selects the most efficient method. The method may be a table scan, or may be scanning one or more indexes if they exist.

When performing a table scan, the query optimizer reads all the rows in the table, and extracts the rows that meet the criteria of the query. A table scan generates many disk I/O operations and can be resource intensive. However, a table scan could be the most efficient method if, for example, the result set of the query is a high percentage of rows from the table.

When the query optimizer uses an index, it searches the index key columns, finds the storage location of the rows needed by the query and extracts the matching rows from that location. Generally, searching the index is much faster than searching the table because unlike a table, an index frequently contains very few columns per row and the rows are in sorted order.

The query optimizer typically selects the most efficient method when executing queries. However, if no indexes are available, the query optimizer must use a table scan. Your task is to design and create indexes that are best suited to your environment so that the query optimizer has a selection of efficient indexes from which to select. SQL Server provides the Database Engine Tuning Advisor to help with the analysis of your database environment and in the selection of appropriate indexes.

computer virus

computer virus

A computer virus is a piece of software that attaches itself to another program to corrupt the program and files on the computer system.
Types of Computer Virus
Computer Viruses are classified according to their nature of infection and behavior. Different types of computer virus classification are given below.
1. Resident virus: They usually fix themselves inside the computer memory. They get activated every time the OS runs and end up infecting other opened files.They hide in RAM.Examples CMJ,Randex,Mrklunky etc.
 2. Overwrite Virus: These types of viruses delete any information in a file they infect, leaving them partially or completely useless once they are infected. Once in the computer, they replace all the file content but the file size doesn’t change.examples trivial.88.D,trj.Reboot etc
3. \Boot sector: A Boot Sector Virus infects the first sector of the hard drive, where the Master Boot Record (MBR) is stored. . If a computer is infected with Boot Sector Virus, when the computer is turned on, the virus launches immediately and is loaded into memory, enabling it to control the computer. examples poly boot,AntiEXE,stone virus,disk killer,form etc
4. Macro virus: Macro viruses infect files that are created using certaing applications e.g ms office suite, these macros are usually stored as part of the document or spreadsheet and can travel to other systems when these files are transferred to another computer.examples Relax,Bablas etc
5. Directory Virus: Also known as cluster virus or file system virus. They infect the computer’s directory by changing the path indicating file location. They are usually located in the disk but affect the entire directory. Example is any file with the extension .EXE or .COM 3
6. \Polymorphic virus: Polymorphic Viruses have the capability to change their appearance and change their code every time they infect a different system.This helps the Polymorphic Viruses to hide from anti-virus software.examples are Elkern,Marburg,etc.
Effects of virus
It causes computer to crash (i.e. to stop functioning normally or to stop responding to other software) Loss of files and corruption of data stored in file.
Virus warning signs 
When a computer is infected with virus, the following symptoms may occur
 Slow system performance
 Presence of tiny dots
 Incomplete saving of files
 Appearance of strange characters
  Corruption of the system set up instructions
 Wandering across the screen
 New windows keep opening up at an alarming rate
 when files and folders getting deleted
  when disks and drives are not working properly
 Sources of Virus
  Infected storage devices such as flash drive ,CD-ROM etc
 By downloading or opening attachments in email from unknown source
 Through internet download
 Installation of infected programs
  opening an infected document
  by downloading cracked and illegal versions of software

MALWARE PROGRAMS
Malware is an abbreviated term meaning malicious software.it is a program that is specifically designed to gain access to or damage the computer files without the knowledge of the owner. It is developed for the purpose of doing harm to files, software and hardware.Computer Virus is one of the examples of malware.
 Other malware programs include;
Computer Worm: This is a program that uses computer network to spread itself.
 Trojan Horses: This is illegal instructions placed in the middle of a legitimate program.It is hidden program that runs on your computer without your knowledge.
Logic Bombs: This type of malware do not replicate, they are designed to destroy data on the computer system once certain conditions have been met.
Spyware: It is written to spy through a legal software.it changes computer’s configuration and personal information.

VIRUS DETECTION SOFTWARE (ANTI-VIRUS) This is a program written by the programmer to get rid of computer viruses. Some anti-virus are programmed to kill the virus and the effect done to the computer while others prevent the virus from entering the computer system. Anti-virus software is computer software used to prevent, detect and remove malicious software. Examples are; karpersky,E-scan,Avast,McAfee, etc

The Art of Information Processing

INFORMATION PROCESSING  
 THE ART OF INFORMATION PROCESSING INTRODUCTION
Information is data that has been processed in such a way that it is meaningful to the person who receives it. Information is also referring to facts and opinions provided and received during the course of daily life. Information processing is the change of information in any manner detectable by any observer. As such it is a process that describes everything that happens (changes) in the universe from the falling of a rock to the printing of a text file from a digital computer system.
 DEFINITION
Information processing is the process of acquiring, obtaining, recording, organizing, Storing and dissemination of information. OR Information processing refers to the manipulation of digitalized information by computers and other digital electronic equipment.
 PROCEDURES FOR INFORMATION PROCESSING 
The procedures for information processing can be categorized into; 1.Collation of information 2.Organisation of information 3.Analysis of information 4.Interpretation of information
1. COLLATION OF INFORMATION: Collation is the assembly of written information into a standard order. Many systems of collation are based on numerical order or alphabetical order. Collation is a fundamental element of most office filling systems, library catalogs and reference books Benefits of collation i. It makes it faster and easy for a user to find an element in the list or to confirm that it is absent from the list. ii. Search operation can be done automatically using the binary search or manual searching. iii.The first and last element can be easily found in a given range.

2.ORGANIZATION OF INFORMATION: Organizing skills helps in arranging information in such a way that it can be used more effectively. This essentially involves the following: 1.Comparing and contrasting 2.Classifying perceptions 3.Ordering perceptions/events 4. Representing ideas/perceptions The nine basic ways of organizing information are: 1.Alphabet 6. Hierarchy 2.Category 7. Chronological 3.Continuum 8. Geographical 4.Location 9.Value Size 5.Time

3.ANALYSIS OF INFORMATION: Since information is the raw material of decision making, it is crucial to learn how to analyze it. Analysis part may be adding up numbers and averaging them or comparing information to examine the relationship of one thing to another or two things together. Two ways to analyze information are; a.) Tally sheets b.) Summary sheets

 4. INTERPRETATION OF INFORMATION: During the interpretation stage, searcher’s assess the usefulness of their information and reflect to develop personal meaning. Information requires interpretation to become knowledge. Interpretation of information involves the following 1) Inferring 2)Drawing conclusions 3)Filtering information (point of view bias etc.) 4) Comparing and contrasting 5) Determining credibility 6) Classifying 7) Evaluating information 8) Evaluating information to support or result a problem or research question...
