In today’s world computer has become an integral part of the business sector for professional
activities not only for professional activities but for personal activities also. As technologies have
evolved networking came into the picture and slowly from initial wired network technology we
moved to this advanced networking technology. Now if we will think then we can know that
networking impacts everything.
Computer Network is an interconnection between computers or we can say computer network is
group of computers interconnected to each other which enables one computer to communicate with
another computer. It acts as basis of communication in Information Technology (IT). It is system
of connected computing devices and shares information and resources between them. The devices
in network are connected by communication links (wired/wireless) and share data by Data
Communication System.
Server administration comprehends all tasks related to managing, optimizing and monitoring servers, networks and systems in order to ensure they work properly and safely. It requires 24/7 availability and monitoring to guarantee business operations at all times.
The role of server administrators is to install, manage, optimize, monitor and solve problems (if necessary) in the company’s servers and related components. To ensure high performance and security, server administrators are responsible for completing a wide list of tasks, including:
*Hardware management and maintenance.
*Application maintenance and updates.
*Backup scheduling.
*Server and system monitoring.
*Performance optimization.
*Access management.
*Technical support and ticketing management.
*Implementing security barriers against cyberattacks.
*Data protection.
*Data center safety, when opting for on-premise servers.
Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. You typically pay only for cloud services you use, helping you lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change.
Not all clouds are the same and not one type of cloud computing is right for everyone. Several different models, types, and services have evolved to help offer the right solution for your needs.
First, you need to determine the type of cloud deployment, or cloud computing architecture, that your cloud services will be implemented on. There are three different ways to deploy cloud services: on a public cloud, private cloud, or hybrid cloud.
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users via ransomware; or interrupting normal business processes.
Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative.
A successful cybersecurity approach has multiple layers of protection spread across the computers, networks, programs, or data that one intends to keep safe. In an organization, the people, processes, and technology must all complement one another to create an effective defense from cyber attacks. A unified threat management system can automate integrations across select Cisco Security products and accelerate key security operations functions: detection, investigation, and remediation.
