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

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
