Bagi teman-teman lulusan SMA/SMK dan sudah mendapat pekerjaan di jakarta, namun ingin melanjutkan pendidikan di perkuliahan jangan risau. pada tulisan kali ini saya akan menjelaskan beberapa tips bekerja sambil kuliah. serta pendapat mengenai universitas terbaik di jakarta

Keputusan untuk kerja sambil kuliah atau sekolah sebenarnya memiliki resiko, tapi tingkat resiko tersebut pasti berbeda-beda berdasarkan pekerjaan yang anda geluti. Setidaknya, anda terkadang merasa kesulitan dalam mengatur waktu antara kuliah dan kerja, apalagi jika pekerjaan tersebut bersifat terikat, anda akan sering dihadapkan oleh kendala-kendala.

Siang kerja di kantor, malamnya lanjut kuliah at sebaliknya. Siang Kuliah, n malem kerja.
Jika dibayangkan, rasanya sulit dan mustahil. Agar sukses menjalaninya, pusiangggggggg...............

Kalo gitu, coba beberapa tipsini:

Stands for Internet Protocol Address of the IP address. Definition of IP address is a numerical identification that is labeled to a device such as a computer, router or printer contained in a computer network that uses the Internet protocol as a means of communication. IP address has two functions, namely:
As a means of identification in the host or network interface.
This function is illustrated as the person's name as a method to identify who the person is. in computer networks apply the same thing.
As the location address of the network.
This function is illustrated as our home address that shows exactly where we are. To facilitate the transmission of data packets, the IP address contains information of its existence. There is a service that must be passed so that the data can get to the destination computer.
IP address using 32-bit numbers. This system is known as Internet Protocol version 4 or IPv4. Currently IPv4 is still used despite existing IPv6 was introduced in 1995. This is due to the high growth in the number of computers connected to the internet. It is necessary to address more of being able to identify many members of the network.

1981, the virus 'in the wild' first discovered. Virus called Elk Cloner spread via floppy disk on an Apple II.

1983, Fred Cohen in his paper entitled 'Computer Viruses - Theory and Experiments' gives the first definition of the computer virus and describes experiments that have been done to prove the concept of a computer virus. Together with Len Adelman, he created an example of a computer virus on a VAX 11/750 with Unix operating systems.

1986 A pair of brothers from Pakistan, Basit and Amjad, creating a first boot sector virus called Brain. Brain is often referred to as the world's first computer virus. PC-based Trojan was first created in the form of a shareware program called PC-Write. In some reports mentioned that the first virus file, Virdem, jugamditemukan in the same year. Virdem created by Ralf Burger.

, 1987, file infector viruses like Leigh began to appear, mostly attacking COM file like COMMAND.COM. In the same year the virus attacker EXE files first, Suriv 01 and 02 as well as Jerusalem. IBM Mainframe IBM worm attack speed replication Christmas Worm with a half million copies per hour.

1988, the first virus to attack the Macintosh computer, MacMag and Scores, appeared. In the same year established CERT (Computer Emergency Response Team) by DARPA with the initial objective to address the Morris Worm attack created by Robert Morris.

Wired or Wireless network without (WiFi) in Indonesian called wireless, is a technology that connects two devices to exchange data without the cable media. Data exchanged through the medium of a particular wavelength of light (such as infrared technology on remote TV) or radio waves (such as bluetooth on the computer and mobile phone) with a certain frequency.

The advantages of this technology is to eliminate the use of wires, which can be quite disturbing the aesthetics, and also the complexity of installation to connect more than 2 devices simultaneously. For example: 1 computer to connect a server with 100 client computers, it takes a minimum of 100 pieces of cable, the length varies according to the distance from the client computer server. If kabel2 is not covered through a special lane (such as cable tray or conduit), it can interfere with the eye sight or interior of a building. This unpleasant sight does not exist on the relationship between devices in wireless technology.

Disadvantages of this technology is the possibility of interference of neighbor relations other wireless devices.

Type - the type of wireless:
WAP (Wireless Application Protocol)

Is a standard for wireless application protocol (as used in mobile phones). WAP is the result of collaboration between the industry to create an open standard (open standard). WAP is based on Internet standards, and some of the protocols that have been optimized for wireless environments, such as the need for data compression, long latency and bandwidth limitations, and the limitations of wireless devices. Design of information transmitted via WAP usually use format WML (Wireless Markup Language). WML is similar to HTML, just more specific to wireless devices that have limitations as above.

WBMP (Wireless Bitmap)

Format charts contained in WAP. WBMP is a similar format to BMP format. WBMP format images with the standard is divided into two parts, namely: q The header section, a place for the characteristics of image information, such as height, width and type of image. q The contents of the so-called Type dependent, is part of the image information.

WBMP format is the standard arrangement can be made with expanded its usefulness. Type part or content can be transformed into formats that can be accessed bare. Although WBMP will slow down the data transfer because the size is not small, but using images can provide more information on a small screen like the handhone.

Wireless LAN (Wireless Local Area Network)

Data communication technology by not using a cable to connect between the client and the server. Wireless LAN technology is generally similar to computer networking technology that uses cable (Wire LAN or Local Area Network). Wireless LAN technology is using radio frequencies to transmit and receive data that would reduce the need for or dependency relationship through cable. As a result, users have a high mobility or flexibility and does not depend on a place or location. Wireless LAN technology also makes it possible to establish a computer network may not be accessible by a computer network that uses cables.

Computer Networking Miscellaneous determined:
1. Based on scale:
Local Area Network (LAN): A computer network that connects a computer to another computer with a distance.
Metropolitant Area Network (MAN): the same principle to the LAN, it's just that the distance is greater, which is 10-50 km.
Wide Area Network (WAN): the distance between cities, countries, and continents. The same with the internet.
2. Based on function:
Client-server
Namely computer network with a dedicated computer as a server. A service / service can be provided by a computer or more. An example is a domain such www.detik.com served by many computer web server. Or it could be a lot of service / services provided by a single computer. An example is a multi-service server with the mail server, web server, file server, database server and others.
