What is an AMC?
An annual maintenance contract is an agreement between the Vendor/Systems Integrator and the customer, which states the terms and conditions regarding the maintenance responsibility taken by the integrator for the customers computers, peripherals etc. It mostly focuses on hardware but large organizations do sometimes go for complete network maintenance contract with having engineers outsourced, at their site.
What is an Antivirus?
An antivirus is a program that protects the system from viruses which come from mostly, the Internet and affects the data.
What is a Firewall?
A firewall is simply a program or hardware device that filters the information coming through the internet connection into your private network or computer system. If an incoming packet of information is flagged by the filters, it is not allowed through.
What is an Mail Server?
A network computer that handles electronic mails is called as a mail server. The real e-mail system consists of two different servers running on a server machine. One is called the SMTP Server, where SMTP stands for Simple Mail Transfer Protocol. The SMTP server handles outgoing mail. The other is a POP3 Server, where POP stands for Post Office Protocol. The POP3 server handles incoming mail.
What is NMS?
A network management system is a service that employs a variety of tools, applications, and devices to assist human network managers in monitoring and maintaining networks.
What is a Proxy Server?
A proxy server (sometimes referred to as an application gateway or forwarder) is an application that mediates traffic between a protected network and the Internet. Proxies are often used instead of router-based traffic controls, to prevent traffic from passing directly between networks. It has two network interfaces, one on each network, and blocks all traffic specified passing through it.
What is a Router?
A router is a device that connects two networks together forming an internetwork. They work on network layer of the OSI reference model. When a computer on a LAN wants to transmit data to a computer on another LAN, the system send its packets to a router on the local network, and the router forwards them to the destination network. In many cases, the destination network is not located on an adjacent network, so the router has to forward the packets to another router. On a large internetwork, such as Internet, packets may have to pass through a dozen or more routers on the way to their destination.
What is a Storage network?
A storage network connects storage and network technologies to deliver a common way to manage, protect, and heterogeneously share information regardless of distance or scale.
What is a Structured Cabling?
Structured Cabling is the practice of establishing a methodology for the organization and indexing of the facilities network topology. A structured cabling system allows changes to occur quickly and cost effectively. It follows set of point-to-point cable segments and is installed according to published guidelines and specifications. The goal is reliable and manageable systems.
What is a Switch?
A switch is a box with multiple cable jacks in it that forwards packets only to their respective destination systems. In this way, it is different from a hub, which forwards every incoming packet out through all of its ports. Because they forward data to a single port only, switches essentially convert the LAN from a shared network medium to a dedicated one .A switch forwards broadcast messages to all their ports, but not unicasts and multicasts.
What is a VSAT?
Short for Very Small Aperture Terminal, an earthbound station used in satellite communications of data, voice and video signals, excluding broadcast television. It describes a small terminal that can be used for one-way and/or interactive communications via satellite. VSAT networks offer value-added satellite-based services capable of supporting the Internet, data, video, LAN, voice/fax communications, and can provide powerful, dependable private and public network communications solutions.
What is a VPN?
A VPN is a private network that uses a public network (usually the Internet) to connect remote sites or users together. It uses encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted. Most VPNs rely on tunneling to create a private network that reaches across the Internet. Essentially, tunneling is the process of placing an entire packet within another packet and sending it over a network.
