The term workstation and desktop are often interchanged, especially in a work environment where both terms are used. A desktop is any computer that can be fit on top of a table or a desk. This was to differentiate against the older and bigger computers. A workstation is the term used for high end computers that are used for scientific or any other heavy usage application. With the introduction of personal computers, the term desktop became very common because these computers can now fit on a desk. But since these computers were often too underpowered for use in some work environments, companies used computers that have better specifications. These computers were called workstations. Workstation is a computer designed for technical or scientific applications. Workstations are more powerful and higher in performance than desktop computers, especially with respect to CPU and Graphics, memory capacity and multitasking capability. Can be used as a server for low level app...
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...
