Computer software is a set of instructions or programs instructing the computer to do specific tasks. Software is basically a generic term used to describe computer programs. In general, scripts, applications, programs and a set of instructions are all terms often used to describe a software. On the basis of language in which software is developed and platform which is required for its execution, we can group different types of software into two categories: System Software and Application Software. Read through this article to find out more about System Software and Application Software and how they are different from ... Read More

As we know that testing is the most important stage in the process of delivery of any application or software. Testing not only validates the quality of an application but also provides an opportunity to the developer to improve its product. Every application is being developed in some high or low level language which means some code has been written for its development so on the basis of execution of code written for the application there is classification of testing namely static testing and dynamic testing. In this article, we will discuss all the important differences between static ... Read More

In a computer system, memory devices are used to store data and information. Computer memories are mainly classified into three types – primary memory, secondary memory, and cache memory. The primary memory is further classified into two types namely – RAM and ROM, where RAM is further subdivided into two types, i.e., SRAM and DRAM. Read through this article to find out how an SRAM is different from a DRAM. What is RAM? RAM stands for Random Access Memory. It is the internal memory of the CPU for storing data, program, and program result. It is a read/write memory ... Read More

Both the Spiral Model and the Waterfall Model are widely used development methodologies in the software industry. Both of these models are practices for better tracking and have application development in systematic way. The basic difference between spiral model and waterfall model is that the spiral model works in evolutionary method and generally used by developers, whereas the waterfall model works in a sequential method and generally used by customers. In this article, we will discuss the important differences between spiral model and waterfall model. But before going into the differences, let's start with some basics of these two ... Read More

In a computer system, a port provides an interface to connect a peripheral device to the computer system. Thus, ports in the computer hardware are the jacks or sockets through which the peripheral devices are attached to the computer system. These ports are standardized for each purpose. There are several types of ports available in the computer system such as USB ports, Ethernet ports, display ports, serial ports, parallel ports, etc. Through these ports, we connect different hardware devices such as monitor, keyboard, mouse, etc. to the computer. Read through this article to find out more about Serial ... Read More

In computer parlance, security and protection are the two terms that seem similar at first glance. Therefore, most people use them interchangeably, but both are quite different from each other. In this article, we will highlight how "security" is different from "protection". Basically, the measures to prevent the interference with use of local and physical resources of computer systems provided by the operating system are known as security and protection. One major difference between security and protection is that security deals with the external threats on the information, while protection handles the internal threats on the information. Before going ... Read More

In computers and other electronic devices, there is an internal storage device called ROM (Read Only Memory). It is a storage device used to store data and instructions permanently. Till date, there are several types of ROMs available such as PROM, EPROM, and EEPROM. There are several differences among all these types of ROMs depending on the manufacturing process, electronic components used, operation, reversibility, etc. In this article, we will discuss the important differences between PROM and EPROM by considering different parameters. But before that, it is important to get an overview of their basics so that it becomes easier ... Read More

Both process and thread are related to each other and quite similar as these are the independent sequence of execution. The basic difference between a process and a thread is that a process takes place in different memory spaces, whereas a thread executes in the same memory space. Read through this article to find out how a process is different from a thread, in the context of operating systems. Let's start with some basics of threads and processes. What is a Process? A process is an active program, i.e., a program that is under execution. It is more ... Read More

Both multitasking and multithreading are the concepts related to the operating system of the computer. One major difference between multitasking and multithreading is that multitasking allows the CPU of computer to perform multiple tasks simultaneously, while multithreading allows the CPU to execute multiple threads of the same process simultaneously. Read through this article to find out more about Multitasking and Multithreading and how they are different from each other. Let's start with some basics first. What is Multitasking? When a single CPU is allowed to execute multiple tasks at the same time, it is called the multitasking. In ... Read More

Both multiprogramming and multitasking are the concepts related to the operating systems of computer. It is not a good practice that keeping the CPU occupied for a single task only. Since, there is a considerable difference between the speeds of the CPU and other components of the computer system. This difference increases the CPU idle time and degrades its throughput. Therefore, to overcome this problem, several concepts such as multiprogramming, multitasking, multithreading, etc. have been developed to improve the CPU utilization. In this article, we will discuss the important differences between multiprogramming and multitasking. Let's start with some basics ... Read More
