Some Terms of Information Technology and Its Meanings which Widely Used Today

The continued development of technology in our day to day, the more terms of information technology that we should know in order to make easier to understand about the technology. So, for those of us who do not know or still do not know what the meaning of the term about information technology we can 'get lost' when reading or view those terms.

To find out what the meaning of the term of the new information technology, below are some terms about information technologies and their meanings:

1. Analog Computer
   It is a term used to describe a computing tool that works on the analog level. Analog level is the opposite of the digital level. Basically, the electronic components are used as the core of the analog computer is the op-amp (operational amplifier).
2. Baseband
   It is a method of using a communication medium is passed through a carrier frequency for Take flow data.
3. Broadband
   This is a term in the internet which is an internet connection high speed data transmission. There are two common types of broadband, DSL and cable modem, that is capable of transferring 512 kbps or more, about 9 times faster than modems that use a standard telephone cable. Countries with the highest penetration of broadband usage in the world is South Korea. For the rating, Broadband has the smallest connection named DS-1 (Tier 1), which has a transmission speed of 1.544 Mbit/s, and the highest named OC-3072 which has a speed of 159.2 Gbit/s.
4. Bandwidth
   The difference between the lowest and highest frequency in a certain range. For example, a phone line has a bandwidth of 3.000Hz (Hertz), which is the range between the highest frequency (3300Hz) and the lowest frequency (300Hz) which can be bypassed by this telephone line.
5. Byte
   Is the term used as the unit of data storage in computers. One byte consists of eight bits. For most small size called kilo bite that has a value of 103 and the greatest named yobi bite which has a value of 280.
6. CPU (Central Processing Unit)
   Refers to computer hardware to understand and execute commands from the software and data. Another term, processor, often used to refer to the CPU. The microprocessor is a CPU that is produced in integrated circuits, often within a single integrated circuit package.
7. CD (Compact Disk)
   It is an optical disc used to store data digitally.
8. Copyright
   It is the exclusive right of the Author or the Copyright Holder to regulate the use of the casting ideas or specific information. In essence, copyright is a "right to copy a creature".

10. Ethernet
    A type of cabling and signal processing for data computer network developed by Robert Metcalfe and David Boggs at Xerox Palo Alto Research Center.
11. GPS (Global Positioning System)
    It is a system for determining position on the earth's surface with the help of the satellite signal synchronization. The system uses 24 satellites that transmit microwave signals to Earth.
12. Hard Drive
    It is a hardware component that stores secondary data and contains the magnetic disk.
13. Hotspot
    Referring to certain places (usually public) who have internet service using Wireless LAN technology, such as at college, mall, plaza, library, restaurant or airport.
14. LAN (Local Area Network)
    The computer network that its network only covers a small area, such as campus computer networks, buildings, offices, in homes, schools or smaller. Today, most of LAN based on IEEE 802.3 Ethernet technology using the switch, which has a data transfer rate 10, 100, or 1000 Mbit/s.
15. Login
    The process to access the computer by inserting the identity of the user account and password to gain access to use computer resources purposes.
16. MIME (Multipurpose Internet Mail Extension)
    Refers to a protocol widely used in the world of Internet that expanding the SMTP (Simple Mail Transfer Protocol) (RFC 822) to allow some of the data other than text in ASCII encoding, such as video, sound, and binary files, so it can be transferred through e-mail without having to first translate these data into ASCII formatted text. MIME is a part of the HTTP protocol, and a web browser and HTTP server will use MIME to interpret the sent and received of e-mail files.
17. Micro Computer
    It is a computer class that uses a microprocessor as the main CPU. Microcomputer also known as Personal Computer (PC), Home Computer, or Small-Business Computer.
18. Server
    It is a computer system that provides a specific type of service in a computer network. The server is supported by a scalable processor and RAM, also equipped with a special operating system, called the network operating system.
19. Software
    It is a general term for data that is formatted and stored digitally, including computer programs, documentation and other information that can be read and written by a computer.
20. Soundcard
    It is a computer hardware used to make a sound and voice recording. At first, Sound Card only as a complement of computers. But now, the sound card is required on each computer.
21. WWW (World Wide Web)
    It is an information space that is used by global identifiers called Uniform Resource Identifiers to know definitely useful resources. WWW is often considered synonymous with the Internet as a whole, even though it is just a part of the Internet.
22. Wireless LAN
    Is a wireless local area network that uses radio waves as the transmission media. The last link used is wireless, to give a network connection to all users in the surrounding area.
