So you want to publish a website to you? Welcome to the club. These days it seems that almost everyone has a website of a kind, and thousands more continue to be launched every day. It’s challenging enough to design a site and fill it with interesting content, but when all is said and done another challenge still remains – where to host?
A popular choice for newbie webmasters, and even more experienced, is to secure a free hosting plan with a company like Yahoo Geocities, Tripod or Angelfire. While these are easy to install and free, they have limitations. Most free hosts do not offer all the nice features that paid hosts do such as FTP access, CGI-BIN, or your own personal domain name.
Instead you’re stuck with minimal features and a generic URL such as [http://www.freewebhost.com/marcswebsite]. This somewhat limited potential of your website. Most free hosts also require you banners or pop-up ads on your website run to make it worth it – these banners and pop-ups can obstruct the view of your web page and ultimately annoy visitors and drive them away. Finally, most free hosts have a daily bandwidth limit that is very small, so if you get a lot of traffic you will probably more than the allotted bandwidth and your site will be temporarily disabled. Overall I would recommend free web hosts for people new to web hosting and want a feel for how it works to get. I’d also recommend them for websites that are personal in nature (such as an online diary) and Web sites that are not going to generate any revenue. Free web hosts are a good stepping stone to paid web hosts – I myself starting building web sites 4 years ago using free hosts, and today I run several high traffic websites that are hosted on paid web hosting plans.
Now is the time to the good stuff – paid web hosting.
Web hosting companies that charge for their services abound on the Internet, and have a wide range of hosting packages at various prices. First we start with the “budget” web hosts, who claim to offer you the world for only $ 1 per month. Have used a large number of similar companies I feel I must tell you that you can proceed with caution, because these companies are not all they are cracked too. Many claim to 24 / 7 email support, which in my experience showed 0 / 0 e-mail support services. My e-mails were either never answered or answered a week after I sent them. Even when I was a response of a general nature and completely useless. Also, expect frequent outages with these budget web hosts as they rarely even have their own web servers – often they are reselling space on someone else’s web servers over which they have no control. One budget web host I used went unexpectedly to 6 days, and they did not even bother to notify their customers. As a result, my web site is down for 6 days and I lost most of my visitors as well as my hard-earned search engine rankings. Lesson learned: if the reliability and success of your website is important to you, budget web hosting might not be the answer. This is not to say that all budget web hosts are bad items – 1dollarhosting.com is one of the leaders in the budget web hosting arena and has quite a reputation.
Tablets, tablets and tablets!! These days there is huge race in launching tablets by the famous tablet makers. Every maker wants to bring some innovation in their newly launched tablets. One more company come in this field of launching latest tablet is Dell. Dell introduces its 10-inch Windows 7 based device which is designed with higher mobility, greater security, immensely manageability all in all features studded in this single tablet.
In the event where Dell announced it’s much awaited products like laptops, mobiles, tablets etc. The greatest attention is grabbing by the Win tablet. The Windows 7 Business Tablet run on an Intel processor is beautifully designed. The tablet come in a 10 inch Android version with smother touch screen. It may be launched somewhere near around September. This is the time to welcome finger-friendly software overlay for Windows 7.

Anyhow, cash entails not anything when you will not go in your system. Just select the choice that you favour and wish this proposal would be helpful for you.
An operating system (OS for brevity) is responsible for the coordination, management of activities, and resource sharing in a computer. Without the OS, it is impossible to operate these devices.
The three most dominant computer operating systems found in the market today are Windows (manufactured by Microsoft), MAC (by Macintosh/Apple Computers), and Linux (by Linus Torvalds and his partners).
Current Windows OS has the best Graphical User Interface with upgraded menu bar, start menu, button, and taskbar appearance. These user-friendly features allow clients to conveniently use computers with just simple instructions. This OS is known to be very stable and is protected with high level of security measures. These have phishing filters that alarm its users when unauthorized people are attempting to access their sites. It also has spam protection, Windows Defender which blocks suspicious programs, advanced firewall, automatic back-up during programs crashes, and data encryption/decryption. This software allows fast inter-connectivity in local area networks and the internet. High-speed data downloading and uploading can be achieved. Multimedia functions such as video and audio are richly provided in Windows OS.
The main disadvantage of Window OS is that this has high computer system requirements. You should have a computer that has very high memory capacity, graphics card requirement ranging from 128 to 256 megabytes, minimum hard disk space of at least 20 gigabytes, and Random Access Memory (RAM) with 2 gigabyte capacity. Windows OS is usually expensive. You may need to upgrade your current software or purchase a new operating system to keep abreast with technological advances.
Macintosh provides its own operating system which is called MAC OS. It is less prone to infiltration and damage from harmful software such as malware and spyware compared to Microsoft Windows. However, this system is not sold solely in computer stores because it is exclusively used in Apple Computers. Because of this, MAC OS equipped units are typically pricey.
The Linux operating system is known for its stability and durability in withstanding long use. This system rarely crashes. If this indeed happens, it will not usually harm its computer programs. It can run even on old computer hardware such as Pentium 100 with 16 megabyte of memory and just 1 gigabyte disk drive. You can still use your outdated computer since several program applications are compatible with Linux. Its security features are very impressive because its developers can immediately fix any weak spots that the operating system may have.
However, Linux has many disadvantages. First of all, many people are not familiar with this computer software. Thus, it will take some time to learn on how to operate it. Secondly, there are a lot of office suite programs that do not run on Linux. Thirdly, you need specialized personnel to service your computer that uses the said operating system. Lastly, there are computer programs that are incompatible with the Linux software. Therefore, these may not run and function properly.
Database Management System (DBMS) :
Database Management System is the collection of programs and tools that enables users to create and maintain the database.
A DBMS is also a general purpose software system that facilitates the process of defining, constructing and manipulating databases for various applications.
Characteristics of Database Management System :
(1) Self Describing
(2) Insulation from Programs and Data Abstraction
(3) Support of Multiple views to Database.
[4] Advantages of DBMS:
1- Controlling Redundancy :
There are provisions in all database models that redundant storage of the data can be avoided.
2- Security Over Unauthorized Access :
This is the feature found in the database that without proper login, no one can modify or store database. The security can not be achieved with the flat file (Sequential) approach.
3- Providing Persistent Storage for Database Objects :
Database can be used as the persistent storage of Program objects, Database and Database structures. This meant that a complex object of programming languages can be stored in the database. This gives more flexibility and compatibility of database over the programming languages.
4- Permitting Inferencing and Actions using Rules :
Inferencing is the method for defining deducing rules for inferencing new information from stored database. Such database are called as Deducible Database. In other words, there must be some methods to provide information by logical implementation on the stored database.
6- Allowing Multiple User Interface :
DBMS has the capability to provide concurrent execution of various parts of the database. In this approach, Deadlock and other anomalies are also handled by the DBMS.
5- Backup and Recovery :
Database Management Systems have proper mechanism to Backup the whole database and recover when any disaster comes to picture. There are methods for Disaster Recovery in all DBMS.
[5] Data Models :
A data model is the set of conceptual tools for describing data, their relation, semantics and consistency constraints. There are following data models-
(1) Hierarchical Model
(2) Network Model
(3) Relational Model
(4) Object Relational Model
Describing all of these would be out of context. You should know that with all these, Relational Model is famous one. Newer implementation of DBMS do follow Object Oriented Model. Such as Oracle, Sybase and SQL Server.
[6] Logical and Physical Data Independence :
Data Independence is the quality of DBMS that ensure the capability to change the database in a manner that the change in one level does not affect the other level. Such as change in the physical storage (Internal Level) does not affect the database structure (Conceptual Level).
(1) Logical Data Independence:
Capability to change the Logical structure without changing the external and internal schema of the database.
(2) Physical Data Independence:
Capability to change the Physical schema without any change in the conceptual schema of the database.
[7] Database Languages :
There are following database languages-
[1] DDL (Data Definition Language)
[2] DML (Data Manipulation Language)
[3] DCL (Data Control Language)
[1] DDL (Data Manipulation Language)
This is the language concerned with the creation of database structure and schema related with this. This language is concerned with the definition of the whole database architecture.
DDL is used to define and manage all the objects in an database. Such as creating Databases, creating security objects that define the whole database.
[2] DML (Data Manipulation Language)
Insertion, Update , Delete and Selection are the activities concerned with the database manipulation language.
DML is used to Select, Insert, Update, and Delete data in the objects defined using DDL.
[3] DCL (Database Control Language)
Database control language is concerned with the consistency maintaining, authorizing access and other control over the database.
There are some other languages which must be known. These are -
VDL (View Definition Language) : Providing means to view the conceptual schema of database for external level of three level schema.
SDL (Storage Definition Language) : Providing means to change or modify the internal schema of the database.
[8] Relational Database :
The Relation database model is based upon the conception of implementing the database with the Mathematical Set Theory. In this model, data is collection of tables called Relation in the set theory. The Tabular representation of data contains rows and columns in which rows represent set of attributes of individual entity and the columns represent the attribute of entity.
A model is also said as Relational Database Model, if it follows complete set of Rules defined by Dr. E.F. Codd. There are 12 Rules of Dr. Codd. In all of them, only Oracle is supposed to follow nearly all of them. But, the best in performance is Sybase which is more easier to configure that of Oracle.
SQL :
SQL is actually Structured Query Language. This is pronunciated as ‘sequel’, but ‘Ess-Que-El’ is also correct.
It was initially named by Dr. E.F. Codd who named it Structured English Query
Language (S E Que L ) as Sequel.
SQL is based on the Relational Model. Nearly all the database implementation in the world are in Relational Model. Sybase ,SQL Server, Oracle,
DB2 are the famous implementation of Relational Model. But these are also kept in the Category of Object Relational Model.
Microsoft Access is not supposed to be relational model. This actually uses some
flavors of relational database. But, can not be taken into account of pure
Relational database.
ANSI-SQL :
American National Standards Institute handles the standards of SQL. The changes
are made time to time. We have ANSI-SQL-89, ANSI-SQL-92 and other standards.
There are several levels decided. Microsoft SQL Server is given entry level.
Conclusion :
This is all about providing protection for passwords. There are many other
things to research in the same scenario and I would like to share my ideas when
such studies are complete. Overall, my aim was to open your eyes that backups
are not only to secure your data, but due to carelessness this may lead to
leakage of information. In my opinion, disclosure of important information is
more serious matter than loss of information. So, awareness is important and
there is a little effort to apply in securing your backups.
