Data Compression refers to a technique that allows a large file to be reduced to a smaller-size. It also allows decompressing the compressed file back into its original form.Lossy compression restores the large file to its original form with some level of loss in data which can be considered negligible, while lossless compression restores the compressed file to its original form without any loss of data.Read through this article to find out more about Lossy and Lossless compression techniques and how they are different from each other.What is Lossy Compression?Lossy compression is a type of data encoding and compression that ...

Both MD5 and SHA1 are hashing algorithms. MD5 is simple and fast, but it does not provide good security. SHA1 is complex as compared to MD5 and it provides greater level of security.Read through this article to find out more about these two hashing algorithms and how they are different from each other.What is MD5?MD stands for Message Digest. MD5 is a hashing algorithm that produces a 128-bit hash value.Although MD5 was created with the intention of using it as a cryptographic hash function, it has been discovered to have several flaws. Yet, it is extensively used.MD5 can be used ... Read More
IPv4 and IPv6 are internet protocol versions, with IPv6 being an upgraded version of IPv4. There are several differences between the IPv4 and IPv6 protocols, including their functionality, but the most important difference is the quantity of addresses (Address space) that they create.Read through this article to find out more about IPv4 and IPv6 and how they are different from each other.What is Internet Protocol (IP)?The Internet Protocol is a set of rules that allows our computers to communicate via the Internet. IP addresses are basically in charge of directing the data packets to their correct destinations. IP controls all ... Read More
In digital electronics, a counter is a sequential logic circuit that consists of a series of flip-flops. As the name suggests, counters are used to count the number of occurrences of an input in terms of negative or positive edge transitions.Based on the way the flip-flops are triggered, counters can be grouped into two categories: Synchronous counters and Asynchronous counters.Read through this article to find out how these two types of counters function and how they are different from each other.What is a Synchronous Counter?If the "clock" pulses are applied to all the flip-flops in a counter simultaneously, then such ...

A SAN is a network of storage devices that can be accessed by multiple servers or computers. It provides a shared pool of storage space. Each computer on the network can access the storage on the SAN as though they were local disks connected directly to the computer. SAN uses SCSI and SATA protocols.NAS are storage devices that are linked to a network and provide file access services to computer systems. These devices generally include an engine that executes the file services and one or more devices on which data is stored. NAS uses file access protocols such as NFS ... Read More
A cluster computer refers to a network of same type of computers whose target is to work as one collaborative unit. Such a network is used when a resource-hungry task requires high-computing power or memory. Two or more same types of computers are clubbed together to make a cluster and perform the task.Grid computing refers to a network of same or different types of computers whose target is to provide an environment where a task can be performed by multiple computers together on need basis. Each computer can work independently as well.Read through this article to find out more about ... Read More
Cloud computing refers to a client-server computing framework where resources are managed in a centralized fashion. It is provided as a pay-per-use service. Cloud computing makes the system all-time accessible.Grid computing refers to a network of the same or different types of computers whose target is to provide an environment where a task can be performed by multiple computers together on a need basis. Each computer can work independently as well. Grid Computing is used internally by organizations.Read through this article to find out more about Cloud Computing and Grid Computing and how they are different from each other.What is ... 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
Streaming refers to the act of viewing the content held on a remote server, whereas Downloading is the process in which all of the data is transferred completely, and then viewed.Read through this article to find out more about Streaming and Downloading and how they are different from each other.What is Streaming?Streaming is the process of viewing the content that is stored on a remote system (server) rather than on a client workstation.In media and application streaming, the media bitstream is broken into discrete chunks (i.e., packets) and sent individually.In media and application streaming, the media bitstream is broken into ...

FTP is an Internet protocol for transmitting or transferring data from one computer to another via TCP or IP networks. TELNET, on the other hand, is a connection protocol that allows a user to connect to a remote server waiting for commands. The user can then give commands to the server and inspect the returned responses, once the connection has been established.Read through this article to find out more about Telnet and FTP and how they are different from each other.What is Telnet?Telnet is a network protocol that allows you to remotely connect to a computer and establish a two-way, ...
