Jaringan nirkabel
(Inggris: wireless network) adalah bidang disiplin yang berkaitan dengan komunikasi antar sistem komputer tanpa menggunakan kabel. Jaringan nirkabel ini sering dipakai untuk jaringan komputer baik pada jarak yang dekat (beberapa meter, memakai alat/pemancar bluetooth) maupun pada jarak jauh (lewat satelit). Bidang ini erat hubungannya dengan bidang telekomunikasi, teknologi informasi, dan teknik komputer. Jenis jaringan yang populer dalam kategori jaringan nirkabel ini meliputi: Jaringan kawasan lokal nirkabel (wireless LAN/WLAN), dan Wi-Fi. Jaringan nirkabel biasanya menghubungkan satu sistem komputer dengan sistem yang lain dengan menggunakan beberapa macam media transmisi tanpa kabel, seperti: gelombang radio, gelombang mikro, maupun cahaya infra merah.

Pada tahun 1970 Norman Abramson, seorang profesor di University of Hawaii, mengembangkan komputer pertama di dunia jaringan komunikasi, ALOHAnet, menggunakan biaya rendah seperti ham-radio. Dengan bi-directional topologi bintang, sistem komputer yang terhubung tujuh ditempatkan lebih dari empat pulau untuk berkomunikasi dengan komputer pusat di Pulau Oahu tanpa menggunakan saluran telepon.

"Pada tahun 1979, FR Gfeller dan U. Bapst menerbitkan makalah di Proceedings IEEE pelaporan percobaan jaringan area lokal nirkabel menggunakan komunikasi infra merah disebarkan. Tak lama kemudian, pada tahun 1980, P. Ferrert melaporkan percobaan penerapan kode satu radio spread spectrum untuk komunikasi di terminal nirkabel IEEE Konferensi Telekomunikasi Nasional. Pada tahun 1984, perbandingan antara infra merah dan CDMA spread spectrum untuk komunikasi jaringan informasi kantor nirkabel diterbitkan oleh IEEE Kaveh Pahlavan di Jaringan Komputer Simposium yang muncul kemudian dalam IEEE Communication Society Magazine. Pada bulan Mei 1985, upaya Marcus memimpin FCC untuk mengumumkan ISM band eksperimental untuk aplikasi komersial teknologi spread spectrum. Belakangan, M. Kavehrad melaporkan percobaan sistem PBX nirkabel kode menggunakan Division Multiple Access. Upaya-upaya ini mendorong kegiatan industri yang signifikan dalam pengembangan dari generasi baru dari jaringan area lokal nirkabel dan diperbarui beberapa lama diskusi di radio portabel dan mobile industri.

Generasi pertama dari modem data nirkabel dikembangkan pada awal 1980-an oleh operator radio amatir, yang sering disebut sebagai radio paket ini. Mereka menambahkan komunikasi data pita suara modem, dengan kecepatan data di bawah 9.600-bit / s, untuk yang sudah ada sistem radio jarak pendek, biasanya dalam dua meter band amatir. Generasi kedua modem nirkabel dikembangkan FCC segera setelah pengumuman di band eksperimental untuk non-militer penggunaan spektrum penyebaran teknologi. Modem ini memiliki kecepatan data yang diberikan atas perintah ratusan kbit / s. Generasi ketiga modem nirkabel ditujukan untuk kompatibilitas dengan LAN yang ada dengan data tingkat atas perintah Mbit / s. Beberapa perusahaan yang mengembangkan produk-produk generasi ketiga dengan kecepatan data di atas 1 Mbit / s dan beberapa produk sudah diumumkan oleh waktu pertama IEEE Workshop on Wireless LAN.

Adapun jaringan nirkabel dalam bidang sensor atau biasa disebut Jaringan Sensor Nirkabel (Wireless Sensor Network/WSN). Jaringan sensor nirkabel adalah jaringan perangkat nirkabel yang saling berhubungan yang tertanam dalam lingkungan fisik untuk mengukur kondisi lingkungan seperti suhu, suara, tingkat polusi, kelembapan, angin, dan sebagainya.

Tips Menghapus Virus ShortCut

Dalam dunia komputerisasi tidak menutup kemungkinan terinveksi oleh virus yang selalu membuat kesal seorang User (pengguna) bahkan mungkin seorang user pesimis dengan virus yang selama ini di alami bahkan seorang user sering kali bertanya-tanya Anti Virus apa yang ampuh untuk mengatasi virus yang selama ini mengganggu dalama komputer/laptop yang mereka miliki, dalam hal ini saya mencoba untuk memberi solusi atas keluhan virus shortcut yang selama ini mengganggu komputer anda semua.

Tampilan seperti ini yang sering membuat seorang user (pengguna)
Entah itu pada Laptop ataupun isi FlashDisk anda.

Berikut ini adalah 8 langkah praktis untuk Menghilangkan virus yang mampu mengubah
folder yang ada di dalam USB flash disk menjadi shortcut tersebut:
  1. Nonaktifkan ‘System Restore’ untuk sementara selama proses pembersihan.
  2. Putuskan komputer yang akan dibersihkan dari jaringan.
  3. Matikan proses virus yang aktif di memori dengan menggunakan tools ‘Ice Sword’. Setelah tools tersebut  terinstal, pilih file yang mempunyai icon ‘Microsoft Visual Basic Project’ kemudian klik ‘Terminate Process’. Silahkan download tools tersebut di http://icesword.en.softonic.com/
  4. Hapus registri yang sudah dibuat oleh virus dengan cara:
    • Klik menu [Start]
    • Klik [Run]
    • Ketik REGEDIT.exe, kemudian klik tombol [OK]
    • Pada aplikasi Registry Editor, telusuri key [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
    • -. Kemudian hapus key yang mempunyai data [C:\Document and Settings\%user%].
  5. Disable autoplay/autorun Windows. Copy script di bawah ini pada

Five Reasons Being a Slow Computer

Your computer suddenly slow when being chased deadlines work? It definitely feels very annoying. But you do not need to rush emotions let alone to slam your computer. The cause slow computer can vary.

In general, a computer / laptop performance will decrease if the memory is approaching full capacity. When you run many applications at once, the main memory load increases. Main memory in a computer (usually RAM) is one of the most important components of a computer system in addition to the processor. The entire application is executed by the processor is taken from the main memory. So when you open too many applications simultaneously while the main memory capacity is small, it will affect overall computer performance

In addition, there are some other things that make the performance of your computer becomes slow. What is it?

1.   Too many add-ons in the browser
Application web browser is one of the most vital applications to support your work. You need this application to surf in cyberspace. Sometimes, for some reason you need additional Functions which by default is not owned by the browser you are using. The additional functions you can get through extensions or add-on. Be sure not to add an add-on that you do not need because it will also add to the burden of memory that ultimately will make the computer become slow
2.   Hard drive capacity thinning
When the capacity of your hard disk is approaching full, the computer will take a little longer to find the files you are looking for. So be advised only if the loading process will be a little slower
3.   main memory
As mentioned above, the main memory is one of the most important components in a computer system. All files required a certain program will be loaded into main memory before being called by the processor. If the main memory capacity is small, you do not should not open too many applications at the same time if you do not want your computer to hang
4.   Too many programs running
Multi-tasking has become a very helpful feature for users to work with multiple programs at once. However, it does not mean you can go around plenty of open applications. You must understand exactly about computer specs that you used before you open too many application programs
5. Virus
Viruses are the most frightening mush for computer users. In addition to stealing important files, computer virus programs will also make your computer becomes slow. Make sure you install proper antivirus and do not be lazy to update the antivirus

The installation of the Local Area Network (LAN)

The chance of this post I try to give something to friends who might be on the enlightenment that I have to say here, many are already familiar with or even go into what I would post this time, something which I will post this time talking about the installation of Local Area Network (LAN). I emphasize on some of the discussion below :
  1. Explaining the network hardware and their functions.
  2. Explains IP addressing Address.
  3. Calculate IP addressing and Subnet Address IP Address.
  4. Explain the network topology.
  5. Topology design specifications required.
Network hardware can be broadly at the start of the computer itself to the device used to endorse a global network. As an example of network hardware that is inside the computer is NIIC or Network Interface Card. NIC is also referred to as LAN Card, LAN Card name is more popular than NIC.

LAN Card
NIC or LAND Card

Out of the NIC is generally connecting it with the switch that is used together with another computer.
Switch
Switch

Router
Router

If the computer networks connected to different networks, It would require a router device. To protect and secure the network are the Firewall, Proxy server. Besides, the partners are still referred to as a bridge network, wireless router, access point, and so forth.

Each network device requires an IP Address, IP Address There are two types of IPv4 and IPv6, which is commonly used IPv4. IP Address IPv4 version consists of 4 groups of 8-bit binary number is converted to a decimal number that is easy to understand.

Biner
Decimal
00000000
0
11111111
255

IP address is divided into five classes, Class A, Class B, Class C, Class D, Class E, but in actual classes used to provide IP address is class A, Class B, Class C.

Class
Biner
Decimal
A
0000 0001.X.Y.Z to 0111 1111.X.Y.Z
    1.X.Y.Z to 127.X.Y.Z
B
1000 0000.X.Y.Z to 1011 1111.X.Y.Z
128.X.Y.Z to 191.X.Y.Z
C
1100 0000.X.Y.Z to 1101 1111.X.Y.Z
192.X.Y.Z to 223.X.Y.Z

Each class has a public IP for the benefit of local interests

Class
IP Local
A
  10.    0.0.0 to   10.255.255.255
B
172.  16.0.0 to 172.  31.255.255
C
192.168.0.0 to 192.168.255.255

Class A has a special IP address that has been allocated for testing the network, which is 127.0.0.0
Write the IP address error will cause the appearance of error messages, for example if address 127.0.0.0 IP address to NIC.

IP Address
Error message when one writes the IP address

Each class has an IP subnet mask to determine the network number and host and user.


Class
Subnet Mask (Default)
A
1111 1111.0000 0000.0000 0000.0000 0000 or 255.0.0.0
B
1111 1111.1111 1111.0000 0000.0000 0000 or 255.255.0.0
C
1111 1111.1111 1111.1111 1111.0000 0000 or 255.255.255.0


As an example of a class C IP address local: 192.168.0.1 with a subnet mask of 255.255.255.0

a number of binary subnet mask = 24, so the IP address 192.168.0.1/24 could be written as a binary number 0 is equal to 8 pieces, then the IP address 192.168.0.1 has a kind friend as much as 28 = 256, that is : 192.168.0.0 to 192.168. 0.255

192.168.0.0 Cannot be used as an IP address for the network, while 192.168.0.255 is the IP address for the broadcast. So the effective number of IP addresses only 256-2 = 254.

Than 1111 111.1111 1111 .1111 1111.0000 0000 can also be 1111 111.1111 1111 .1111 1111.1000 0000 or 1111 111.1111 1111 .1111 1111.1100 0000

Subnet Mask 1111 1111.1111 1111.1111 1111.1100 0000 Have a number of binary 1 = 26 and the number of binary 0 = 26

So for the same IP address 192.168.0.1/26, subnet mask of 255.255.255.192.
Binary 1 at the end of = 2 and a binary 0 = 6
binary 1 indicates the number of network = 22 = 4
Binary 0 indicates the host for each network26 = 64
IP Address in the table it can be:

IP Address

192.168.0.0
Network 1
192.168.0.1 to 192.168.0.62

9 The Causes Slow Computer Performance

As a computer user, of course we all want a good computer performance, fast response, smooth data access without having to wait a long time and so on. There is therefore good that we know what the cause or an effect with a slow computer. The following brief review 9 of the most frequent causes slow computer performance plus tips or solution.

1. Malware (virus, worm, trojan, dsb )

When computers are exposed to malware (viruses, worms, trojans, and the like), it's almost certain that okmputer performance will be slow. The virus will often use the computer's resources either RAM or CPU, as well as continuously monitoring computer activity. It is certainly very influential on the performance of other applications.
The solution to prevent this for users of Windows is to install antivirus and not just stop there, but regular antivirus updates. Schedule at least once a week if the computer is not online.

2. Spyware, Adware and The Like

If we often use the computer to the internet for, if not careful there is a possibility the computer may be infected with spyware. The effect may not be so great with the computer's performance, but it could have an effect on Internet access, and various things that disturb the comfort of surf and worse, important data (user, password, account, etc.) we can know by the creator of this spyware.
Solutions can install Anti-spyware is also constantly updated, just need to be sorted out which ones are not much use of my resources (resources) of our computer, because it is not uncommon Antispyware uses the CPU and Memory that is large enough. If antivirus is included, we do not need to add. Or use a portable version, and regularly scan for spyware only.

3. The number of applications running in the background

The more our computers with software, usually the more slow computer performance, although there is a relatively small effect and there are great. It is important to note when installing software, check whether an application is always running behind. This can be in the know with programs like Autoruns.
The solution in this case is important to use the software only, select a software if there is some similar software or have similar features and if there is a portable version of it then it could be an alternative. To reduce the program running in the background, use Autoruns, and disable unnecessary background applications. To to see whether the application is installed to run the program in the back, install software such as WinPatrol.

4. Hard disk (HDD) that have been age

When computers are still using the hard disk that is long enough (old), may be more than 5 years, then get progressively slower computer performance. To check, we can use free software HDD Tune and the like (read the article: Check the condition of your Computer Hard Disk). Normal SATA HDD usually average read access (read) about 70-90 MB / s. If for example the average HDD access below 50 MB / s then the performance will usually feels slow.
Solution when the hard drive is very slow, may be tried with full format (beware, data backup first). Although the old hard drive to it typically will not help much, so it is best to replace a new hard drive, and if you still want to use the old hard drive, use as a secondary hard drive only.

5. RAM / Memory mediocre

Many of the least amount of RAM / memory that we use can not be made a standard equal to one computer to another computer or even the operating system. Although when it will install Windows, there is a minimum specification of RAM, but the type of application that we use must also be taken into account. To check, just open the Task Manager and in the Performance check the PF Usage and also showing the total Physical Memory Physical Memory (RAM) and the remaining available (Available).

If we are not running any applications, but the rest of RAM is more than half, usually the computer's performance will be slow, then it should be checked any application that uses lots of memory (RAM), generally can be checked at the Process , Mem Usage column . If indeed we are barely adequate RAM (eg Windows XP with 512 MB of RAM or less, windows 7 with 1 GB of RAM), then the cheapest solution is to reduce the applications that consume a lot of memory. The best solution is to upgrade memory (RAM) (read: Know what RAM).

6. Conflicts applications or programs installed

Not infrequently two applications in the same category could result in conflict, further slowing computer performance. Signs of conflict forged the troubled computer after you install the software, whereas previously there was no problem. What often happens is usually in the category of conflict security software, such as antivirus.
For example we use 2 antivirus or more. Although some antivirus can run concurrently, but still not recommended, except for expert users or for trial. Not to mention when it still had to install other security software.
If there is an alternative variety of similar software, then if possible choose one that can represent, and superior in performance and results. Especially for the many types of software to access the resources or the operating system.


7. Selection Software inappropriate

Not a few people just went along with (trend) in the use of software, but there is actually a desirable feature in other software that is small and free. If we are indeed minimal computer specs or we want to work quickly, then choose the right software. Software with a large size is not always better and more appropriate for each of us. Here are some examples:
When we just want to burn data to CD / DVDs, exact solutions can use ImgBurn software that measures just about 5 MB or other free burning software that is relatively smaller than installing Nero Multimedia Suite which is about 354 MB.
When we work with compressed data (zip, rar), free software like 7zip that measures just about 1 MB should suffice, rather than install Winzip 15 measuring nearly 13 MB and is also not free (free compression software, etc.)
If using Photoshop 7 or CS1 / 2 is sufficient for the needs of graphics, then install Photoshop CS5 need difikir repeated, because the required specification is quite high, so it can work more slowly.

8. The amount of software installed

Although the software is installed is not running behind, but almost every software always adds an entry (data) to the registry, so that more and more software is installed is the size of the registry (windows) will also be greater. Because the registry will be accessible both when the computer is running and is already running, the size also affects the speed / response time was.
The solution is to use software that's required course, Uninstall software that is not important and use the uninstaller like Revo Uninstaller to make the process more thoroughly uninstallasi. To clean the software has been uninstalled on, can also use a variety of free Utilities.

9. Effects of excessive use of Windows

The use of Windows berlebihWindows Securities Xp, Vista and Windows 7 provides the option to use a display with various effects. If your computer has good specs, of the various effects is not a problem, but if you want faster performance, the effects of windows can be deactivated.
For example Windows XP, right-click My Computer, select the Advanced tab and click the Performance setting. We also put through the system tweaked to get the settings right and quickly, using software such as X-Setup Pro.


 

Actually, in addition to the above 9 things are still many other reasons, such as various service windows that are running are actually not necessary, selection and arrangement of hardware that is not optimal, the primary disk space (for example, drive C:) which limits or on the verge of running out, and others (ebsoft)
