management services

Hardware diagnosis and failure alert are handled by ____. a. management services b. communication services c. access services d. Internet services

peer to peer

In a(n) ____________________ network, every computer can communicate directly with every other computer.

servers

Often, separate LANs are interconnected and rely on several ____ running many different applications and managing resources other than data. a. workstations b. servers c. clients d. stand-alone computers

unified communications

The centralized management of multiple types of network-based communications, such as voice, video, fax, and messaging services.

management services

The network services that centrally administer and simplify complicated management tasks on the network. Examples of management services include license tracking, security auditing, asset management, address management, software distribution, traffic monitoring, load balancing, and hardware diagnosis.

mail services

The network services that manage the storage and transfer of e-mail between users on a network. In addition to sending, receiving, and storing mail, mail services can include filtering, routing, notification, scheduling, and data exchange with other mail servers.

backbone

The part of a network to which segments and significant shared devices (such as routers, switches, and servers) connect. A backbone is sometimes referred to as "a network of networks" because of its role in interconnecting smaller parts of a LAN or WAN.

convergence

The phenomenon of offering multiple types of communications services on the same network is known as ____. a. convergence b. unified communications c. divergence d. multi-communications

address management

The process of centrally administering a finite number of network addresses for an entire LAN. Usually this task can be accomplished without touching the client workstations.

license tracking

The process of determining the number of copies of a single application that are currently in use on the network and whether the number in use exceeds the authorized number of licenses.

load balancing

The process of distributing data transfer activity evenly so that no single device is overwhelmed.

A+

The professional certification established by CompTIA that verifies knowledge about PC operation, repair, and management.

internet services

The services that enable a network to communicate with the Internet, including Web servers and browsers, file transfer capabilities, Internet addressing schemes, security filters, and a means for directly logging on to other computers.

soft skills

The skills such as customer relations, oral and written communications, dependability, teamwork, and leadership abilities, which are not easily measured, but are nevertheless important in a networking career.

NOS (network operating system)

To function as a server, a computer must be running a(n) ______________________________.
