For What Is 'Microsoft SQL Server' Used?In Feburary 2016 29,

In Feburary 2016 29,
SQL Server uses the client-server model of data management. With client-server, a program called the client requests data from a server program, usually on another computer. The server evaluates the request and passes data back to the client. This improves security since the client must provide the correct password information for the server to release the data. It also helps speed data access since the server computer does all the hard work of data management; the client receives the results. An organization using SQL Server usually has several dedicated computers for it.
Relational Database
You can organize data in many different ways. You can type it in a simple file, organize it in a spreadsheet or divide .it into distinct parts. If you run a big website and have millions of records to manage, efficiency is important. Microsoft SQL Server uses a data organization method called a relational database. A database designer looks at the organization's information and creates structures called tables to store it. By linking the tables in different combinations, she can, for example, see how many customers she has by state, what they purchased and how often they visit the website.
SQL Language
SQL Server uses the SQL language. Using SQL, a programmer can create tables, add, remove or update data, and sort and retrieve it rapidly. Different software companies, such as Oracle and MySQL, also use the SQL language, allowing programmers to use the same skills for managing data stored on different systems.
Tools
The core of SQL Server is the program that processes data requests from client programs. In addition, it has programs to build databases, import and export data and monitor the database's performance. While a programmer can do many of these tasks from the SQL language, the extra software tools make the job easier to learn and perform.
Security and Integrity
If you're responsible for a company's data, you need to manage who can and cannot access it. With SQL Server, you can assign many different levels of security, letting some users see or modify data and locking other users out. It also lets a programmer build rules into the database to ensure the data has integrity. For example, the customer's address can have a rule that the state must come from a list of state abbreviations. If a user tries entering a state of 'ZX,' SQL Server will reject it.

How to Calculate Network ThroughputIn Feburary 2016 05,

In Feburary 2016 05,
Convert the TCP window size from bytes to bits: 64 KB is the default TCP window size for computers running the Windows operating system. To convert the window size to bits, multiply the number of bytes by eight. 64 KB x 8 = 524,288 bits.
Divide the TCP window size in bits by the network path latency. For this example, use a latency of 60 milliseconds. 524,288 bits / .060 seconds = 8,738,133 bits per second.
Convert the result from step 2 to megabits per second by dividing the result by 1,000,000. In this example, the maximum throughput is 8.738 Mbps maximum network throughput with the main limitation on the network throughput being the high latency of the network connection.
