What is computer communication and networks? Computer communications is a type of data transfer to each other to share the data based on the network type which means a communication between two or more than two computers included data cable or wireless medium uses the microwaves to transfer the data to the connected computer system through the network device in the network model and the user can share the data to each other to make a communication system based on the digital data sharing by sending files and messages to each other. The network device, the data cable, application software, computer system and resources to make a network model for sharing depends on the capacity of data cable and network device to transfer the data to each other. 1. Computer Communication: This is the process of exchanging data and information between computers and other devices. It enables the sharing of resources, information, and services across systems. 2. Computer Networks: These are interconnected ...

What is the function of a distributed database? Distributed database is a type of database technology that provides the flexibility of access information for the client user or admin user. Distributed database provides many servers to access the information on the website or a particular computer system. Distributed database accessed from the website functions of query programs to manipulate and retrieve the database The multiple location situated servers of the database provides the distributed data to recover or access the information from the nearby server which reduces the latency of data transfer to the computer system of the client user. The manipulation commands can be applied on the distributed database such as:- updating the database file, records deleted or changing the information, insert the new record into the table of relational database model which is distributed on the distributed server to the multiple location. The distributed ledger is based on the distributed databa...

What is the purpose of a digital data communication system? Digital database communication system is a communication based on the digitization which includes the digital transmission of the data with signals forms of 1 or 0 based techniques to detect and identify the digital signals. The data can be transferred to the user if the user is connected to the network to sender user on the network model or internet services. Digital communication generally uses the communication models: TCP/IP, OSI model, Peer to peer connection, PAN etc. that are used to provide the communication and the data sharing system to connect to each other computer using their request based method to accept the request by the user on the data communication system. Let’s takes an example on the digital data communication system following below here:- If the user is try to send the file which has a size of 30 mb (megabyte) to the connected user on the data communication model in the network model then how much can ta...

What are the four main objectives of distributed systems? Introduction of transparency of the distributed systems:- The user can share the user interface of the operating system of the computer system that provide the user interface and functionality for performing the task on the distributed system that provide the service without disturbing or buffering of task and the user doesn't need to waiting for the results if the one system failure. The user easily uses the database and access the information from the particular computer system and resources which are connected in the distributed systems. The user can use the data which is saved on the other computer but the computer location is hidden from the user interface to use the distributed system as the distributed is same for all users on the distrbuted system to use the services. Distributed systems can be increases the system for enhancing it known as scalability:- The objective of distributed system increases the computer syst...
