Local Area Network (LAN) is used to connect a group of networked devices to allow communication between them, whereas Virtual LAN is used to enhance the performance of multiple LANs.Read through this article to find out more about LAN and VLAN and how they are different from each other.What is LAN?A local area network (LAN) is a network limited to a particular geographic area. A switch, or stack of switches, connects a group of computers and devices using the TCP/IP protocol's private addressing mechanism.Private addresses are distinct from those of other machines on a local network. Routers are used to ... Read More

Both DES and AES are symmetric-key block ciphers that are used in encryption where just one key (the secret key) is utilized to encode and decode electronic data. The key must be exchanged between the organizations communicating using symmetric encryption so that it can be utilized in the decryption process.Go through this article to find out the features of AES and DES ciphers and how they differ from each other.What is DES Cipher?The Data Encryption Standard, often known as DES, is a symmetric key block cypher developed by IBM in 1977.Plaintext is divided into two halves in DES encryption, and ...

Ethernet is a set of protocols that are used primarily in LANs, although they can also be used in larger networks like MANs and even WANs. Ethernet was first standardized in the 1980s as the IEEE 802.3 standard. Since then, it has seen several upgrades and its data carrying capacity kept increasing with each upgrade. Standard Ethernet can support data speeds up to 10 Mbps. Fast Ethernet can carry data at a maximum speed of 100 Mbps. With Gigabit Ethernet, the data speeds reached a maximum speed of 1 Gbps. 10-Gigabit-Ethernet can carry data at incredibly high speeds of ... Read More

A LAN is a computer network that is limited to a particular geographic area. Ethernet, the other hand, is a LAN network standard used in wired LAN. Go through this article to find out more about the features of Ethernet and LAN and how they are different from each other.What is Ethernet?Ethernet is a widely used LAN standard. Ethernet refers to networking technologies and systems used in local area networks (LANs) to connect computers inside a single physical space. It is defined under IEEE 802.3 standards. It is very easy to understand, implement, maintain and is a low-cost implementation. It ... Read More

SDRAM and DDR are two different types of RAM. SDRAM was released in 1993 and the latest variant of SDRAM are DDR1, DDR2 and DDR3. SDRAM stands for Synchronous Dynamic Random Access Memory. SDRAM was very common before the release of DDR. SDRAM is a single data rate memory. On the other hand, DDR stands for Double Data Rate. As the name indicates, DDR provides double data transmission in each clock cycle as compared to SDRAM. Read through this article to find out more about SDRAM and DDR and how they are different from each other. What is SDRAM? SDRAM ... Read More

BOOTP, Bootstrap Protocol, is used to configure the host and get the host address along with bootstrap info. DHCP, Dynamic Host Configuration Protocol Server is an extended version of BOOTP and is used to configure the hosts dynamically.Read through this article to find out more about these two protocols and how they differ from each other.What is BOOTP?The Bootstrap Protocol is a networking protocol that allows a configuration server to provide an IP address to network devices automatically in Internet Protocol networks. RFC 951 was the first to define the BOOTP.When a network-connected machine wakes up, its IP stack sends ... Read More

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

Volatile memory and non-volatile memory are two distinct types of computer memory with significant differences in terms of their functionality and data storage characteristics. Volatile memory is used for temporary storage and loses its data when the power is removed, while non-volatile memory is used for permanent or long-term storage and preserves data even when the power is off. What is Volatile Memory? Volatile memory is a type of computer memory that requires a continuous power supply to retain data. This means that when the power is turned off or interrupted, the data stored in volatile memory is lost. The ... Read More
