What is the abstract view of the components of a computer system?
A computer system consists of many resources like hardware and software, which are useful to complete a task. The common required resources are input/output devices, memory, file storage space, CPU etc.The operating system acts as a manager for all the above resources and allocates them to specific programs and users, whenever necessary to perform a particular task. Therefore, the operating system is the resource manager that means it can manage the resources of a computer system internally. The resources are processor, memory, files, and I/O devices.An operating system is the interface between the user and the machine. Before there were ...
Read MoreWhat are ultra-dense networks and new services and applications in 5G networks?
Let us understand what an ultra-dense network is.Ultra-Dense NetworkThe dense networks deliver the best of the user experience to the users. This type of network allows the users to get the best result by the use of the densification. The density here can be the absolute or relative density in the networks.The user density networks increase the density too potentially beyond its range to fulfill the customer demand. In the user defined network, the capacity grows as the capacity of the base station also increases. This type of network provides users with the best of experience with the densification approach.In ...
Read MoreWhat are the challenges faced by transport layer protocol?
In the OSI (Open System Interconnection) model, the transport layer is one of the seven layers and it is responsible for the end to end communication between the sender and receiver over the internet. It provides logical communication between the sender and receiver and ensures the end to end delivery of the packet.The transport layer main protocols are as follows −TCP (Transmission Control Protocol)UDP (User Datagram Protocol)SCTP (Stream Control Transmission Protocol)RDP (Reliable Data Protocol)RUDP (Reliable User Datagram Protocol)Responsibilities of the transport layerThe responsibilities of the transport layer are as follows −It provides a process to process delivery or end to ...
Read MoreDifferentiate between Arp and BGP
BGP stands for Border gateway protocol. It is used to exchange the routing information between the networks. It makes the internet work. It always selects the local path preference. Because of the below reasons it is choosing the path than the best path.- Firstly RIP (Routing Information Protocol) selects the path with lowest hop count.- OSPF (Open Shortest Path First) selects the path with the lowest cost. This is more important.- The best path in internet depends on how we are forwarding the traffic and to which autonomous system instead of the shortest path.- Higher local preference path is preferred.-Shortest ...
Read MoreWhat are the basic building blocks of IPSec VPN tunnelling?
The basic building blocks of the IPsec vpn tunnelling are as follows −Authentication header − it is used to verify the identity of the sender of the data and to check whether it is altered or not. It ties data in every data packet to a verifiable signature. It is used for the purpose of authentication.Encapsulating security payload − the data in the data packet is scrambled by using the encryption technique to prevent the sniffing attacks. It ensures the confidentiality of the data as the data is encrypted and not being able to be understood by anyone except the ...
Read MoreWhat are network troubleshooting tools?
The network troubleshooting tools are classified into two types −Hardware toolsThe hardware tools included in the network troubleshooting are explained below −Cable testerIt is also known as a media tester. It is used to test whether the cable works properly or not. The cable testers will confirm whether a cable works correctly and if there is a problem with the cable. Tools which are used for testing of the cable can be classified as a cable tester.Protocol analyserThis tool is used to analyse the network protocols like UDP, TCP, and FTP etc. This acts as a software as well as ...
Read MoreWhat are security features of the 4G cellular network?
4G cellular network is actually the fourth generation of cellular communications.Features of 4GIt comes up with many features which are given below −10x high speed as compared to 3GThe cost is also less for each bit used.It is highly secured too.It comes up with LTE i.e. Long term evaluation which refers to high-speed data connection for mobile devices.Now let us talk about the security features of 4G.Security features of the 4G cellular networkSecurity features are the different types of security measures a 4G network possesses such as the following −Configuration of security − It is the most beautiful feature of ...
Read MoreWhat are VLAN, NAT and private IP’s in computer networks?
Let us begin by learning about Virtual LAN (VLAN).Virtual LAN (VLAN)VLANs are logical grouping of devices which are in the same broadcast domain. Computers, servers, network devices are connected logically and their physical location don't matter. We use VLANs to manage traffic, to make the security improved.A VLAN is used when multiple LAN devices are connected to each other, where each can sneak into the data transmitted by two devices, can be seen by a third device and security can be breached.A VLAN will make sure that the data is kept only between two devices. It can be used to ...
Read MoreWhat is big data?
In simple language, big data is a collection of data that is larger, more complex than traditional data, and yet growing exponentially with time. It is so huge that no traditional data management software or tool can manage, store, or can process it efficiently. So, it needs to be processed step by step via different methodologies.The Applications of Big Data areBanking and SecuritiesCommunications, Media and EntertainmentHealthcare ProvidersEducationManufacturing and Natural ResourcesGovernmentInsuranceRetail and Wholesale tradeTransportationEnergy and UtilitiesThe Uses of Big Data areLocation TrackingPrecision MedicineFraud Detection & HandlingAdvertisingEntertainment & MediaReal World Big Data ExamplesDiscovering consumer shopping habits.Personalized marketing.Fuel optimization tools for the transportation ...
Read MoreWhat are the general techniques to improve the quality of service?
Quality of service (QoS) in the case of networking implies the ability of a network to provide reliable service to the traffic over various technologies including Ethernet, wireless, IP, Asynchronous Mode etc.QOS in case of network congestion must keep in record various elements causing this congestion. It may be due to the reason of low bandwidth or high traffic on a single route. So, routing protocol being used heavily impacts the Quality of service of networking. It depends on how efficient a routing algorithm is to detect the traffic on a particular route and to choose a route accordingly to ...
