DEFINITION OF ACCESS POINT (AP)

A. DEFINITION OF ACCESS POINT (AP)
Here are some definitions of the Access Point (AP) taken from various sources.
Access Point is a network device that contains a transceiver and antenna for transmitting and receiving signals to and from remote clients. With access points (AP) wireless clients can quickly and easily to connect to a wireless LAN network cabling.

Wireless Access Point (WAP / AP) is a device used to connect devices in a network, and from the network Wireless Router and Access Point is a two-function network appliances that work together to form a wifi signal transmitter unit. Access Point form a hot spot, while the Router set of traffic data. This tool is used for Internet Access in wifi.
Access point, access point, abbreviated to AP. A place that became the center of some of the connections are connected. This tool is also known as Cross Box. If viewed from the perspective of telephone connections, the Access Point is a box where the phone cable from the telephone subscribers connected. Similarly, if viewed from a computer network without wires (wireless), access point is a transmitter that connects computers that are connected with the network to reach a larger network (internet).
Access Point is a hub for wireless networks whether in the room, or on the network in the city. For the network in the city, the Access Point is usually at his place in the ISP are on the tower with a height of 20 meters or more.

evolution of memory development

S I M M
Stands for Single In-Line Memory Module, a module or a memory chip that is attached on one side of the PCB circuit. This type of memory has only a number of legs (pins) of 30 and 72 pieces.
30 pin SIMM form of FPM DRAM, widely used in the processor-based systems 386 and 486 final generation earlier generations. SIM pin 30 with a capacity of 1MB, 4MB and 16MB.
While the 70 pin SIMM can be either FPM DRAM and EDO DRAM is used together with the final generation of the processor 486 and Pentium. 70 pin SIMM is produced in the capacity of 4MB, 8MB, 16MB, 32MB, 64MB and 128MB.
EDO RAM
In 1995, were created the kind of memory Extended Data Output Dynamic Random Access Memory (EDO DRAM), which is a refinement of the FPM. EDO memory read cycle can shorten it so that it can improve performance about 20 percent. EDO has an access time is quite variable, which is about 70ns to 50ns and working at a frequency of 33MHz to 75MHz. Although EDO is an improvement of FPM, but both can not be installed simultaneously, because of differences in ability. EDO DRAM memory is widely used in systems based on Intel 486 and Pentium compatibles as well as earlier generations.
D I M M
Short for Dual In-Line Memory Module, a module or a memory chip that is placed on both sides of the PCB, each reversed. DIMM memory is produced in two different forms, namely the number of legs 168 and 184.
DIMM 168-pin can be either Fast Page, EDO and SDRAM ECC, with capacities ranging from 8MB, 16MB, 32MB, 64MB and 128MB. While the DIM pin of DDR 184 SDRAM.
