A web application is an application program that is stored on a remote server and delivered over the internet through a browser interface.

They are used for carrying out different function for and by a user.Web application includes online calculator, e-commerce stores, web mail.

Web applications are built by web developers using text editors, programming languages, plugins e.t.c. Click here to get to know more about computer science and Computer science feilds. (https://bgcomputerscience.com.ng/ )

Websites consist of several web pages linked together.

There are two types of considerations;

Front End Consideration
Back End Consideration
Front End is concerned with the user visual interface or graphic user interface, basically the interface design and the design standard.

Interface design deals with;

Images and graphics
keyboard shortcuts
Drag and drop functions
Hyperlinks
Tables and frames
Pop up menus which are used to create the user interface of a website.
Design standards entail understanding the client's requirements, putting the following in mind;

Target market of the client
Objective of the website.
Sales strategy followed by the client.
Media used by the client
Back End Considerations includes fast download and easy access of to back-end databases, which enhances the user's interest in a website.

Back End Web Development involves the server-side interaction withe browser using programming languages such as PHP, javascript(server-side scripting), mysql(database), java, python e.t.c

Computer network is a group of computer systems and other computing hardware devices that are linked together through communication channels to facilitate communication and resource-sharing among a wide range of users.

Uses Of Network

File sharing
Allows several users to share a single hardware device e.g. printer
Allows for sharing of operating system or software on remote system
Facilitate Communication via email, video conferencing, instant messaging e.t.c
Easy access of information among users.
Types Of Network

Local Area Network(LAN): This is the interconnection of computers that are geographically close, i.e., in the same building.

Wide Area Network(WAN): This is the connection of computers which are largely apart via radio or line waves.

Metropolitan Area Network(MAN): It involves connecting computers within the same town or city.

Home Area Network(HAN): A network contained within a user's home that connects a person's digital devices.

Intranet: This is a network that is local to a company(resources can be retrieved by users within the company without having to go outside the company).This may be LANs, private WANs and MANs.

Extranet:This is an extended intranet, where certain internal services are made available to known external users or external business partners at remote locations.

Internet: This is when an unknown external users need to access internal resources in your network. In other words, your company might have a website that sells various products, and you want any external user to be able to access this service.

Virtual Private Network:This is a secured network type. A VPN is used to provide a secure connection across a public network, such as an internet. Extranets typically use a VPN to provide a secure connection between a company and its known external users or offices.

1)Mysql an open source database which have various alternatives and majorly used in a Linux environment while SQL language is used for querying databases.

2)Structured query Language used to access, maintain store and manipulate data while mysql is a relational database management system that allows you to process data by comparing it with other data sources.

3)SQL server uses a single engine to store data while mysql uses multiple engines ,this gives mysql developers the privilege to store data on the engine of their choice based on the requirements they desire.

4)SQL allows you cancel mid-query executions while mysql does not .

5)Based on IDEs ,MySQL boasts Oracle’s Enterprise Manager, while SQL Server uses Management Studio (SSMS).
