49. What are some general OSHA guidelines to use when using power (electric) tools or other hand tools in the workplace?

Some general OSHA guidelines for using power tools or other hand tools in the workplace are as follows: *Wear personal protective equipment (PPE) to protect yourself as you work. For example, wear eye protection where dust or fumes are generated by power tools. *Keep all tools in good condition and properly store tools not in use. Examine a tool for damage before you use it. *Use the right tool for the job and operate the tool according to the manufacturer's instructions and guidelines. Don't work with a tool unless you are trained and authorized to use it. *Watch out for trip hazards, so you and others don't stumble on a tool or cord. For example, keep power tool electrical extension cords out from underfoot, and don't leave hand tools lying around unattended.

42. What are some of the typical elements that might be present in a fire suppression system, and what do they do?

A fire suppression system in a data center typically includes the following: * emergency alert system-These systems vary, but they typically generate loud noise and flashing lights. Some send text and voice message alerts to key personnel, and post alerts by email, network messages, and other means. * portable fire extinguishers-Note that electrical fires require a Class C fire extinguisher. * emergency power-off switch-Don't use a power-off switch unless you really need to; improper shutdowns are hard on computers and their data. * suppression agent-This can consist of a foaming chemical, gas, or water that sprays everywhere to put out the fire.

43. What is the difference between a WAN, MAN, CAN, and a PAN?

A group of LANs that spread over a wide geographical area is called a WAN (wide area network). A group of connected LANs in the same geographical area-for example, a handful of government offices surrounding a state capitol building-is known as a MAN (metropolitan area network) or CAN (campus area network). The smallest network is a PAN (personal area network), which is a network of personal devices, such as the network you use when you sync your smartphone and your computer.

50. Explain the two different categories of Application layer protocols, and then detail the PDU used at this layer.

Application layer protocols are used by programs that fall into two categories: *Application programs that provide services to a user, such as a browser and Web server using the HTTP Application layer protocol *Utility programs that provide services to the system, such as SNMP (Simple Network Management Protocol) programs that monitor and gather information about network traffic and can alert network administrators about adverse conditions that need attention. Data that is passed between applications or utility programs and the operating system is called a payload and includes control information. The two end-system computers that initiate sending and receiving data are called hosts.

48. How can you prevent damage to a component prior to touching it?

Before touching a component, first ground yourself using one of these methods: *Wear an ESD strap around your wrist that clips onto the chassis or computer case, which eliminates any ESD between you and the chassis and its components. *If you don't have an ESD strap handy, be sure to at least touch the case before you touch any component inside the case. This is not as effective as wearing an ESD strap, but can reduce the risk of ESD. *To protect a sensitive component, always store it inside an antistatic bag when it's not in use. In addition to protecting against ESD, always shut down and unplug a computer before working inside it.

47. Describe how the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) differ from each other, and provide examples of where each might be used.

The Transmission Control Protocol (TCP) makes a connection with the end host, checks whether the data is received, and resends it if it is not. TCP is, therefore, called a connection-oriented protocol. TCP is used by applications such as Web browsers and email. Guaranteed delivery takes longer and is used when it is important to know that the data reached its destination. The User Datagram Protocol (UDP) does not guarantee delivery by first connecting and checking whether data is received; thus, UDP is called a connectionless protocol or best-effort protocol. UDP is used for broadcasting, such as streaming video or audio over the Web, where guaranteed delivery is not as important as fast transmission. UDP is also used to monitor network traffic.

46. Explain the differences between a physical topology and a logical topology.

The term physical topology, or network topology, mostly applies to hardware and describes how computers, other devices, and cables fit together to form the physical network.
