A Domain Name System (DNS) server is used to translate domain names to IP Addresses and vice versa. DHCP is a client/server protocol that automatically assigns an IP address and other configuration information to an Internet Protocol (IP) host.Read through this article to find out more about DNS and DHCP and how they are different from each other.What is DNS?DNS is a hierarchical and decentralized naming system for computers, and other resources that are connected to a private network or the Internet. It connects a variety of bits of data to domain names assigned to each of the participants.DNS transforms ... Read More

UMA and NUMA are shared memory models. Multiprocessors are divided among these type of categories. In UMA, Uniform Memory Access, a single memory controller is used and it is applicable for general purpose applications and time sharing applications. In NUMA, Non-Uniform Memory Access, multi memory controllers are used. NUMA is suitable for real-time applications and time critical applications.Following are the important differences between UMA and NUMA.Sr. No.KeyUMANUMA1DefinitionUMA stands for Uniform Memory Access.NUMA stands for Non Uniform Memory Access.2Memory ControllerUMA has single memory controller.NUMA has multiple memory controllers.3Memory AccessUMA memory access is slow.NUMA memory accsss is faster than UMA memory.4BandwidthUMA has ...

In computer systems, memory is a hardware component of the system that stores data and information in the computer. The computer memory can be classified into two main types namely – primary memory and secondary memory. The primary memory is further divided into two main types – RAM and ROM. Read through this article to find out more about RAM and ROM and how they are different from each other. Let's start with some basics of RAM and ROM. What is RAM? RAM stands for Random Access Memory. RAM is a type of primary memory of a computer system. ... Read More

Hubs are basic network devices that operate at the Physical Layer and they do not perform packet filtering or addressing function; they send the data packets to all the connected devices. Switches, on the other hand, function at the Data Link Layer to connect several devices in a network. Switches are mostly utilized to transmit data packets between various network devices such as routers and servers.Read through this article to find out more about hubs and switches and how they are different from each other.What is a Switch?A switch is essentially a piece of hardware or a device responsible for ...

Both Routers and Modems are network connecting devices. Routers work at the network layer and are responsible to find the shortest path for a packet, whereas Modems connect a device like desktop, laptop to the Internet. Routers connect devices across multiple networks. Read through this article to find out more about Routers and Modems and how they are different from each other. What is a Modem? A modulator-demodulator, or a modem, is a piece of hardware that transforms data from a digital format designed for direct communication between devices using specific cabling into a format suitable for transmission via ...

Both Routers and Bridges are network connecting devices. Routers work at the network layer and are responsible to find the shortest path for a packet, whereas Bridges connect various devices in a network. Routers connect devices across multiple networks. Read through this article to find out more about routers and bridges and how they are different from each other. What is a Router? A router is a networking device that receives, processes, and sends data packets from one computer network to another. On the Internet, routers are in charge of traffic steering. Data packets are used to send data across ... Read More

Routers connect devices across multiple networks. Read through this article to find out more about these two network devices and how they operate to understand how they are different from each other. What is a Router? Routers are network connecting devices that determine the shortest path for a packet to take to get to its destination. A router's primary function is to connect ... Read More

Stop and Wait protocol is a protocol for flow control mechanism. In this protocol, the sender sends one frame at a time and waits for acknowledgment from the receiver. Once acknowledged, the sender sends another frame to the receiver. Stop and Wait protocol is also a protocol for flow control mechanism. In this protocol, the sender sends multiple frames at a time and retransmits the frames which are found to be corrupted or damaged. Read through this article to find out more about these two protocols and how they are different from each other. What is Stop and Wait ... Read More

The process of turning plain text into an encrypted form (cipher text) is known as encryption. Sensitive data is transmitted in an encrypted form so that it can be protected and a strong encryption mechanism ensures that the data is not misused even if a hacker gets hold of it. Decryption is the reverse mechanism where the encrypted cipher text is converted back into its original form.Read through this article to find out more about encryption and decryption and how they are different from each other.What is Encryption?Encryption is the procedure of encoding data in cryptography. This procedure turns plaintext, ... Read More

What is an IP Address? An IP address (Internet Protocol address) is a numerical identifier, such as 192.0.2.1, that is associated with a computer network that communicates using the Internet Protocol. An IP address is used for two purposes: identifying a host or network interface, and addressing a specific location. An IP address has two primary functions: it identifies the host, or more particularly its network interface; and it indicates the host's position in the network, allowing a path to be established to that host. IP addresses can be either Public or Private. Read through this article to ... Read More
