Commonly used types of UTP cabling.

-
 Commonly used types of UTP cabling are as follows:
• Category 1—Used for telephone communications. Not suitable for transmitting data.
• Category 2—Capable of transmitting data at speeds up to 4 megabits per second (Mbps).
• Category 3—Used in 10 BASE-T networks. Can transmit data at speeds up to 10 Mbps.
• Category 4—Used in Token Ring networks. Can transmit data at speeds up to 16 Mbps.
• Category 5—Can transmit data at speeds up to 100 Mbps.
• Category 5e —Used in networks running at speeds up to 1000 Mbps (1 gigabit per          second [Gbps]).
• Category 6—Typically, Category 6 cable consists of four pairs of 24 American Wire 
   Gauge (AWG) copper wires. Category 6 cable is currently the fastest standard for UTP.

What’s The Difference Between 802.11n And 802.11ac?

This article explains the difference between the currently popular IEEE wireless local-area network (WLAN) standard 802.11n and the forthcoming 802.11ac, which defines a faster version The 802.11 standard was first available in the late 1990s. It was not an immediate success. When the 11b version arrived in 1999, it facilitated the first widespread implementation of WLAN technology. The 802.11b standard is often considered the first generation, 802.11a is the second generation, 802.11g is the third generation, and 802.11n is the fourth generation. When 802.11ac becomes available this year, it will represent the fifth generation. Today, the most widely implemented form is 802.11n, which is used in access points, routers, laptops, smart phones, tablets, and other mobile devices. Devices using 11n are all backward compatible with older 802.11a/g equipment. The 802.11 standard defines both a physical layer (PHY) and media access control (MAC) layer in the networking scheme.

1. How Many Layers are There in an OSI Reference Model? Name them. Ans. There are 7 Layers in an OSI (Open Systems Interconnection) Reference Model. They are: (1)   Physical Layer (2)   Data Link Layer (3)   Network Layer (4)   Transport Layer (5)   Session Layer (6)   Presentation Layer (7)   Application Layer 2. How Many Types of Network ? Area Base Network-  LAN, MAN, WAN, CAN, SAN, PAN Architecture Base Network-  Client-Server Network, Peer-to-Peer Network Topology Base Network-  Star, Ring, Bus, Mesh, Tree, Hybrid 3. What is the Difference Between Full Duplex and Half Duplex Devices? Answer: A Full Duplex Device is Preferable, because a Full Duplex Device can Send and Receive Data Packets Simultaneously.  However, with a Half Duplex Device, the Device Must Finish Receiving a Message Before it Can then Send a Message. This can Lead to  Slower Trans...
