NEW QUESTION # 215
CORRECT TEXT
Fill in the blank with the appropriate term. The ______________model is a description framework for computer network protocols and is sometimes called the Internet Model or the DoD Model.
Answer:
Explanation:
TCP
/IP
Explanation:
The TCP/IP model is a description framework for computer network protocols. It describes a set of general design guidelines and implementations of specific networking protocols to enable computers to communicate over a network. TCP/IP provides end-to-end connectivity specifying how data should be formatted, addressed, transmitted, routed and received at the destination. Protocols exist for a variety of different types of communication services between computers. The TCP/IP Model is sometimes called the Internet Model or the DoD Model. The TCP/IP model has four unique layers as shown in the image. This layer architecture is often compared with the seven-layer OSI Reference Model. The TCP/IP model and related protocols are maintained by the Internet Engineering Task Force (IETF).
NEW QUESTION # 216
Which RAID level system provides very good data performance but does not offer fault tolerance and data redundancy?
Answer: D
Explanation:
RAID level 0, also known as striping, provides very good data performance because it spreads data across multiple disks, which can significantly increase speed for read and write operations. However, it does not offer fault tolerance or data redundancy. If any single disk fails in a RAID 0 setup, all data in the array is lost, making it unsuitable for mission-critical systems.
NEW QUESTION # 217
Which of the following is designed to detect unwanted changes by observing the flame of the environment associated with combustion?
Answer: D
NEW QUESTION # 218
Which of the following devices allows wireless communication devices to connect to a wireless network using
Wi-Fi, Bluetooth, or related standards?
Answer: B
Explanation:
A wireless access point (WAP) is a device that allows wireless communication devices to connect to a wireless
network using Wi-Fi, Bluetooth, or related standards. The WAP usually connects to a wired network, and it can
transmit data between wireless devices and wired devices on the network. Each access point can serve
multiple users within a defined network area. As people move beyond the range of one access point, they are
automatically handed over to the next one. A small WLAN requires a single access point. The number of
access points in a network depends on the number of network users and the physical size of the network.
Answer option C is incorrect. A wireless network interface card (WNIC) is a network card that connects to a
radio-based computer network, unlike a regular network interface controller (NIC) that connects to a wire-
based network such as token ring or ethernet. A WNIC, just like a NIC, works on the Layer 1 and Layer 2 of the
OSI Model. A WNIC is an essential component for wireless desktop computer. This card uses an antenna to
communicate through microwaves. A WNIC in a desktop computer is usually connected using the PCI bus.
Answer option A is incorrect. ExpressCard, a new standard introduced by PCMCIA, is a thinner, faster, and
lighter modular expansion for desktops and laptops. Users can add memory, wired or wireless communication
cards, and security devices by inserting these modules into their computers. ExpressCard slots are designed to
accommodate modules that use either Universal Serial Bus (USB) 2.0 or the PCI Express standard.
ExpressCard modules are available in two sizes, i.e., 34 mm wide (ExpressCard/34) and 54 mm wide
(ExpressCard/54). Both modules are 75 mm long and 5 mm high. An ExpressCard/34 module can be inserted
in either a 54 mm slot or a 34 mm slot, but an ExpressCard/54 requires a Universal (54 mm) slot. However, an
extender can be used with ExpressCard/34 slot to connect the ExpressCard/54 module from outside of the
computer. Both the modules are identical in performance. They take full advantage of the features of the PCI
Express or USB 2.0 interfaces. The only difference between them is that the ExpressCard/54 form-factor, due
to its larger surface area, allows for greater thermal dissipation than does an ExpressCard/34. As the
performance does not vary with module size, module developers usually prefer to fit their applications into the
smaller ExpressCard/34 form factor. But some applications, such as SmartCard readers, and CompactFlash
readers, require the extra width of an ExpressCard/54 module.
Answer option D is incorrect. A wireless repeater is a networking device that works as a repeater between a
wireless router and computers. It is used to connect a client to the network when the client is out of the service
area of the access point. If the wireless repeater is configured properly, it extends the range of the wireless
LAN network.
