What are the differences between Firewall and VPN? The use of computers today is extensive and all jobs are mostly done online. This has surely eased daily life and business activities but it has also brought in some demerits along with it. These include: Plagiarism Phishing Digital fraud Pharming Hacking and Several virus threats. Therefore, …
What are the differences between Firewall and router? A Firewall is a strong barrier that is located between two networks and is used to determine the authenticity of the network traffic with the implementation of access control policy. However, just like a router, a Firewall also works on the network layer of the Open System …
A Firewall is firmware, software or hardware that disallows unauthorized access to a system or especially to a network. The Firewall inspects the network traffic, both inbound and outbound, by using a set of rules of its own as well as the predetermined policies of the particular organization. A Firewall should not be mixed up …
The expansion bus of a computer is something which allows doing just that – expansion of the system. This is facilitated by a series of wires and protocols and by inserting PCBs into the slots. These Printed Circuit Boards are also referred to as expansion boards. The computers usually used an expansion bus known as …
Dynamic Random Access Memory in computers is also referred to as DRAM more commonly. It is one of the most common RAM modules and is typically found in the personal computers as well as in the servers and workstations. The primary function of the DRAM is to store information. It comes with cells with a …
A drive in a computer refers to the physical device that is connected to the motherboard of it. These drives typically come in different types of hard drives and are mainly used as the primary storage medium of the computer. A drive can also come in the form and shape of a DVD drive which …

What is channel I/O? A computer needs to communicate between different components in it and for that it needs to transfer data through the I/O channel. This channel is also referred to as input channel simply and it helps in communicating data between the memory and the I/O to the CPU or any other computer …
In simple words an SD card reader is a data input device. This has the ability to read the files stored in a data storage medium which is in the shape of a card. Any modern card reader is able to read several types of plastic cards. These cards may be embedded with many different …
Cache Only Memory Architecture, often denoted as COMA, refers to a specific computer memory organization. This type of architecture is usually found in the multiprocessors where the local memory such as the Dynamic Random Access Memory or the DRAM is typically used as cache in every node. Ideally, this is what makes the COMA much …
Cache line refers to the block of memory that is moved to the cache memory. This cache line is usually fixed in size and ranges from 16 bytes to 256 bytes. However, the size of the cache line will depend largely on the type of application. Some people however get confused and mix up cache …
