Internet access speeds are calculated from the amount of data sent in a unit time. If we send the 1kb files / sec, mean we have to send 1000 bytes, with 1 byte = 8 bits, the data sent equal to 8000 bits = 8 kbps (kilo bits per second). For larger units use traditional Mbps (mega bits per second) means 1000 kbps.
ComponentsThere are several components that can affect the processing speed, among others:
RegisterCPU contains a small memory areas called registers. Its function is to store data and instructions during processing. Size register (also called word size) determine the amount of data that can be used by a computer at a time. At this time most of the PC (Personal Computer) has a register of 32 bits, meaning the CPU can process 4 bits of data each time.
RAMThe amount of RAM on your PC can affect the speed of the system. The more RAM on a PC, the more programs and instructions that can be stored in memory, and much faster than stored on your hard disk. If the PC does not have enough memory to run the program, data will be moved temporarily to the hard disk (this process is called swapping) and this will decrease computer's performance.
Clock SystemClock in a computer system to set the CPU speed using a vibrating quartz crystal. The clock movement is the time required by the transistor to turn off the transistor and then turn it back. This is called a clock cycle, measured in Hertz. If a computer has a speed of 300 MHz, which means that the system clock beats 300 million times per second.
BusBus is the path between components - components in the computer. The data and instructions to walk on this path. Wide data path can affect how many bits that can be transmitted between computer components.
Cache MemoryCache memory is high speed memory that stores data and instructions that have been loaded by the latest CPU. Cache memory is faster than usual, and greatly affect computer performance. There are two types of cache memory, the Level-1 (L1) and external cache is called Level -2 (L2).
Types of Internet Access SpeedAccess speed will depend on network technologies around the distance and the distance / environmental conditions while an internet connection made. The development of information and communication technologies now allow us to mengoneksikan computers with internet in several ways. There are several choices of the type internet speeds that can be used. Here is the internet speed in accordance with the selected channel
Dial - UpTelephone networks have penetrated more widely, so that we can mengoneksikan computer with internet. How to connect computers to the internet using the phone cord is often called the Dial - Up. Dial-Up through the PSTN (Public Switched Telephone Network), will connect us to the ISP Telkom. Connection to a Dial-Up is generally used individuals who want to connect the internet from home. Computers that are used are usually a single computer (not a computer network) speed Internet access using a Dial-Up can reach a maximum speed of 56 Kbps.
ADSLAsymetric Digital Subscriber Line (ADSL) is a modem technology that works at a frequency of 34 kHz - 1104 kHz. This is the main cause of differences in data transfer speed between the modem and ADSL with a conventional modem that works at a frequency of less than 4 kHz. Advantages of ADSL provides high-speed Internet access capability and voice / fax simultaneously (on the customer by using the splitter to separate the phone line and modem lines.)
GPRSGPRS (General Packet Radio Service), is a data and voice communications are performed using radio waves. GPRS has the ability to communicate data and voice on mobile communication devices (mobile). GPRS system can be used to transfer data (in the form of data packets associated with e-mail, data, picture (MMS), and search (browse) the Internet. GPRS service is installed on the type of phone type GSM and IS-136, although the current GPRS network separately from GSM GPRS promises to speed in his theory began 56 kbps - 115 kbps, thus allowing access to the Internet, and multimedia data transmission to computers, notebooks and handheld computers.
3G3G is third generation technology, which refers to the development of wireless telephone technologies (wireless). 3G as a wireless solution that could provide access speeds: As much as 144 kbps for the conditions of fast motion (mobile) As much as 384 kbps to running condition (pendestrian) A sum of 2 Mbps for static conditions somewhere
HSPAHigh Speed Packet Acsess is the result of the first wave of 3G technology development Release 99 (R99) so that HSPA is able to work much faster when compared with R99 connection. Related CDMA networks; HSPA can be equated with Evolution Data Optimized (Ev-Do), which is the development of CDMA 2000. HSPA network largely spread on the spectrum of 1900 MHz and 2,100 MHz, but a few runs at 850 MHz. Spectrum yag greater use because the operator can reach a wider area and its ability to refarming and reallocation of UHF spectrum.
HSPA provides data transmission rates differ in the data stream down (downlink) HSDPA (High Speed Downlink Packet Access) and the current rise (uplink) HSUPA (High Speed Uplink Packet Access), related to the development standards which made the Third Generation Partnership Project (3GPP) continued development of HSPA to further facilitate access to the virtual world as a neat feature and advanced fiber so as to reduce the cost per mega-bit data transfer.
Wireless LANWireless LAN technology works by using radio waves. This technology was originally designed for office applications indoors. However, now the Wireless LAN can be used in peer to peer network in the room and also point to point outside the room and point to multipoint bridge applications. Wireless LANs are designed very modular and flexible. This network can also be optimized in different environments, can overcome geographic constraints and the complexity of the cable installation.
BroadbandBroadband Internet technology is generally defined as a network or Internet service that has a high transfer rate due to the large width of the data path. Normal transfer speed promised by broadband service to about 128 kbps or more. Broadband networks can be used by many groups, ranging from students, hobbyist games, up to the office - small office and branch offices that want to have connections with headquarters that mrmiliki a high enough speed. The most common broadband technologies are used in Indonesia for connecting to your internet connection is DSL technology, cable and fixed wireless technology. Each - each media possess its own advantages and disadvantages.
