Data Compression refers to a technique that allows a large file to be reduced to a smaller-size. It also allows decompressing the compressed file back into its original form.Lossy compression restores the large file to its original form with some level of loss in data which can be considered negligible, while lossless compression restores the compressed file to its original form without any loss of data.Read through this article to find out more about Lossy and Lossless compression techniques and how they are different from each other.What is Lossy Compression?Lossy compression is a type of data encoding and compression that ...

In the context of computer systems, a program or task in execution is called a process. In modern computers, several types of processes are used. The process of selecting one process from a bunch of processes and assigning it to the processor for execution is referred to as scheduling. The component of the system that accomplish this task is called a scheduler. There are two main types of schedulers, namely, Long−Term Scheduler and Short−Term Scheduler. In this article, we will discuss the important differences between long−term scheduler and short−term scheduler. But before that, let's start with some basics of long−term ... Read More

JSP and ASP are both server-side scripting languages. JSP is Java based and is developed by Sun Microsystems, whereas ASP is developed by Microsoft and is also referred as Classic ASP. Whenever a browser requests a JSP or ASP page, the server engine reads the file, executes the code in file and returns the HTML output to the browser.JSP is compiled, whereas ASP is interpreted. ASP.NET is a .NET based variant of ASP where the codes are compiled to improve the performance.What is ASP?ASP is a server-side scripting engine, which means the code that is written gets sent to the ...

Both FTP and SFTP are file transfer protocols and they are used to transfer files from one system to another. FTP does not use any secure channel to transfer files, whereas SFTP uses SSH protocol to establish a control connection. SFTP is highly secure than FTP.Read through this article to find out more about FTP and SFTP and how they are different from each other.What is File Transfer Protocol (FTP)?FTP stands for File Transfer Protocol; it is a client/server protocol for sending files to and from a host computer. User names and passwords can be used to authenticate FTP.Some websites ... Read More

Digital as well as Analog Systems, both are used to transmit signals from one place to another like audio/video. Digital systems use binary format as 0 and 1, whereas analog systems use electronic pulses with varying magnitude to send data. Read through this article to find out more about digital and analog systems and how they are different from each other. What is a Digital System? A system of components like a computer which uses discrete time signals to operate is called a digital system. Digital systems uses such signals that have square shaped waveforms. Digital systems first accept the ... Read More

Cloud computing refers to a client-server computing framework where resources are managed in a centralized fashion. It is provided as a pay-per-use service. Cloud computing makes the system all-time accessible.Grid computing refers to a network of the same or different types of computers whose target is to provide an environment where a task can be performed by multiple computers together on a need basis. Each computer can work independently as well. Grid Computing is used internally by organizations.Read through this article to find out more about Cloud Computing and Grid Computing and how they are different from each other.What is ...

As processes are loaded and removed from memory, the free memory space is broken into little pieces. It may so happen after sometime that processes cannot be allocated to memory blocks considering their small size and memory blocks remain unused. This problem is known as Fragmentation. There are two types of fragmentation namely, Internal Fragmentation and External Fragmentation. Read this article to learn more about these two types of fragmentation and how they are different from each other. What is Internal Fragmentation? Internal fragmentation is defined as the difference between memory allocated and the memory space required by a process. ... Read More

When you search the Internet, do you know whether you are browsing the internet or just surfing? Next time you go on the Internet, you may relate to the following points to decide whether you are browsing or surfing. What is Browsing?

In simple terms, browsing is an act of looking for information and reading about a specific topic with a particular goal or ... Read More

SQL (Structured Query Language) is a computer language which is used to interact with an RDBMS (Relational Database Management System). It is basically a method of managing, organizing, and retrieving data from a relation database. In SQL, two important concepts are used namely, function and procedure. A function calculates the results of a program based on the inputs provided, whereas a procedure is used to perform some tasks in a specific order. There are many other differences between functions and procedures, which we will discuss in this article. What is Function? A function, in the context of computer programming languages, ...

LANs are privately owned and span a smaller geographical area (restricted to a few kilometers). It can be used in various settings, including offices, residences, hospitals, and schools. The setup and management of a LAN is quite straightforward. Just like a traditional wired LAN in which the connected devices transmit data over Ethernet cables, whereas in a WLAN, the connected devices transmit data through Wi-Fi. Mobile users can connect to a WLAN through wireless connection. The IEEE 802.11 group of standards describe the technologies for LANs. Go through this article to find out more about LAN and WLAN ...
