New Storage Systems
Modern storage systems are designed to handle large data volumes with reliability, scalability, and cost-effectiveness. The three significant developments are SAN, NAS, and iSCSI. SAN Fibre Channel Block-level access NAS Ethernet / LAN File-level access iSCSI SCSI over IP Block-level over Ethernet Storage Area Networks (SAN) SAN is a high-speed dedicated network of storage devices configured as nodes, allowing flexible attachment and detachment from servers. SANs use Fibre ...
Read MoreNetwork Attached Storage in DBMS
Network Attached Storage (NAS) is a dedicated storage device connected to a network that allows multiple clients to store and access files. In DBMS, NAS serves as a storage solution for database files, backups, and shared data without requiring a full server. NAS Storage Device LAN (Ethernet) DB Server Web Server ...
Read MoreDifference between Google Fi and Ting
Both Google Fi and Ting are Mobile Virtual Network Operators (MVNOs) that provide telephone calls, SMS, and mobile broadband services using existing cellular networks and WiFi. They differ primarily in pricing models − Google Fi offers fixed monthly plans, while Ting follows a pay-as-you-go approach. Google Fi Google Fi is a wireless service provider operated by Google. It offers access to multiple cellular networks and seamlessly switches between them for the best signal. In the US, Google Fi operates on T-Mobile, Sprint, and US Cellular networks. Plans start at $20 per month and include unlimited calls, messages, WiFi ...
Read MoreDifference between Optical fibre and Coaxial cable
Optical fibre and coaxial cable are both types of guided media used to transmit data over a network. Optical fibre is made of plastic and glass and transmits signals as light pulses, whereas coaxial cable is made of plastic and copper wires and transmits signals as electrical signals. Optical Fibre Optical fibre uses thin strands of glass or plastic to carry data as pulses of light. It offers extremely high speeds, very low signal loss over long distances, and is immune to electromagnetic interference. However, it is more expensive and complex to install. Coaxial Cable Coaxial ...
Read MoreDifference between Cyber Security and Information Security
Cyber Security and Information Security are often used interchangeably, but they differ in scope. Cyber security deals with protecting networks, computers, and data from unauthorized electronic/digital access. Information security deals with protecting information assets regardless of whether the information is in physical or digital format. It is important to note the difference between data and information. Not all data is information − data becomes information when it is interpreted in context and given meaning. For example, "14041989" is just data, but when we know it is a person's date of birth, it becomes information. Hence, all information is data, ...
Read MoreCyber System Security
The Cyber System generally means the word related to a group of computers or Information Technology. Cyber security means the security of cyber systems. It provides a wide range of functions namely Information Technology, Networking, Computer systems, and mainly cyber security operations. Cyber System Security secures the computer system from cyber-attacks. It protects the system and the personal data, credentials, and passwords. Due to the developments in technology, the risks, and the cost to retain the services becoming higher. Cyber System A system that utilizes cyberspace is referred to as a cyber system. Information infrastructures, as well as individuals ...
Read MoreDifference Between GAGAN and GPS
GPS is a navigation system that is based on satellite and users can use it to reach their destination as they will be able to know the location and route of the place where they have to go. GAGAN is developed by ISRO which helps to make the GPS signals accurate. In this article, we will discuss the difference between GAGAN and GPS. What is GPS? The full form of GPS is Global Positioning System. This is a system in which a network of satellites is used in space to know the location of a certain place all over the ...
Read MoreDifference between IP address and Port Number
Computers can communicate with each other over a network through port numbers and IP addresses. In this article, we will discuss the difference between IP Address and Port Number. What is an IP Address? IP Address can be expanded to Internet Protocol Address. This is an address which is used by a computer to receive data and information from other computers through the Internet. Billions of IP addresses are being used to make a connection between computers. These computers use either IPv4 or IPv6 addresses for making a connection. Previously IPv4 was used for networking as the number of users ...
Read MoreExplain the functions of a Physical Layer
The physical layer meets all these requirements out. The set of rules and procedures for interaction between physical layers are called Physical layer protocols. The layer provides a physical connection different from the physical transmission path because it is at the bit level while the transmission path is at the electrical signal level. This physical connection can be a point to point physical connection or point to the multi-point physical connection, as shown in the figure − The physical layer provides its services to the data link layer, the next higher layer of the OSI model. The ...
Read MoreWhat are Computer Registers in Computer Architecture?
Computer registers are high-speed memory storing units. It is an element of the computer processor. It can carry any type of information including a bit sequence or single data.A register should be 32 bits in length for a 32-bit instruction computer. Registers can be numbered relies upon the processor design and language rules.The instructions in a computer are saved in memory locations and implemented one after another at a time. The function of the control unit is to fetch the instruction from the memory and implement it. The control does the similar for all the instructions in the memory in ...
