Answer 1

1. Local access network

A local-area network (LAN) is a computer network that spans a relatively small area. Mostly, a LAN is confined to a single room, building or group of buildings.

2.PABX equipment

A private automatic branch exchange (PABX) is an automatic telephone switching system within a private enterprise.

3.Broadband

Broadband is wide bandwidth data transmission which transports multiple signals and traffic types. The medium can be coaxial cable, optical fiber, radio or twisted pair.

4.Access network field engineering

Accessing network field engineering is accessing network mainframe to provide maximum network infrastructure, security and performance to the end users.It also includes engineering solutions for communication-based subjects such as wireless telephony services, radio and satellite communications, internet and broadband technologies.

5.Voice over IP and PABX installation

Voice over Internet Protocol (VoIP) is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet.

PBX stands for Private Branch Exchange, which is a private telephone network used within a company or organization. The users of the PBX phone system can communicate internally (within their company) and externally (with the outside world), using different communication channels like Voice over IP, ISDN or analog.Installation of PBX includes setup of such networks.

6.CCNA

CCNA (Cisco Certified Network Associate) is an information technology (IT) certification from Cisco Systems. CCNA certification is an associate-level Cisco Career certification.

7.Rectifiers

A Rectifier is an electrical device composed of one or more diodes that converts alternating current (AC) to direct current (DC). A diode is like a one-way valve that allows an electrical current to flow in only one direction. This process is called rectification.

8.Chiller Plants

A chiller plant is a centralized system that cools the air for a building or for a collection of buildings and provides the air-conditioning portion of HVAC systems.

9.UPS

An uninterruptible power supply (UPS) is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails.
