Both Firewall and Antivirus are security tools that protect the computer systems as well as the network infrastructure from virus, worms, Trojans, and other such cyber-threats. Firewalls scan and evaluate the data packets before they enter into a network, and then they either allow or deny the data packets based on certain predefined rules setup by the network protocols. Firewalls can be implemented both at the software and hardware levels, while an antivirus program can be implemented only at the software level. Read through this article to know more about Firewall and Antivirus and how they are different from each ... Read More

As of now, Intel is taking few of the last breaths left in the colossally competitive smartphone and tablet market. Intel drained out millions and billions of dollars in developing and marketing its mobile processor department. The PC chip manufacturer couldn’t stand a chance when it had to face the likes of Qualcomm and Mediatek as per my opinion.Inside IntelAccording to an Intel spokesperson, the company had to cancel two of its Atom-based chips immediately. These chips were code-named, Sofia and Broxton. These are perhaps the first few products that Intel has terminated for bringing in a revamp in its ... Read More

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

In asymmetric multiprocessing, all the processors are not identical and they follow a master-slave relationship; whereas in symmetric multiprocessing, all the processors are identical and they share the main memory. Read this tutorial to find out more about asymmetric and symmetric multiprocessing, and how they are different from each other. Let's start with a basic overview of asymmetric multiprocessing. What is Asymmetric Multiprocessing? Asymmetric multiprocessing is the use of two or more processors handled by one master processor. All CPUs are interconnected but are not self-scheduling. It is used to schedule specific tasks to a CPU based on priority and ... Read More

Both OCR and MICR are types input devices that use character recognition technologies to convert printed data into digital signals that can be processed by a computer. The most basic difference between an OCR and an MICR is that an OCR (Optical Character Recognition/Reader) uses optical effects for character recognition, while an MICR (Magnetic Ink Character Recognition/Reader) uses magnetic effects for character recognition. Read this article to find out more about OCR and MICR and how they are different from each other. What is OCR? OCR, short for Optical Character Recognition, is a technology to convert scanned documents into ... Read More

A computer is a system, i.e. it consists of several parts. The two crucial parts of a computer system are – hardware and software. Those parts of computer system which are physical and visible are called the hardware. Whereas, the computer software are the sets of instructions and programs that enable the computer hardware to perform their functions. Both the hardware and software are dependent on each which means we must install the software in the hardware to make it functional. In the same way, the hardware parts of a computer must be present in the system to perform the ... Read More

Concurrency and parallelism are related concepts in the context of software development, but they have different meanings. Concurrency is the ability of a system to execute multiple tasks using a single processing unit. Parallelism, on the other hand, uses multiple processing units to execute multiple tasks simultaneously, in parallel. Read this article to learn more about concurrency and parallelism and how they are different from each other. What is Concurrency? The technique used for reducing the response time of a system using a single CPU is termed as concurrency. Concurrency is the method that requires only a single processing unit ... Read More
