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.

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

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)

Protects your PC on infected e-mail

Here are some simple rules to reduce the risk of playing into the hands of the virus infected e-mail

1. Consider all business and personal emails as potentially dangerous. If ever in doubt, delete it!


2. The "From:" field can be easily faked to look like it came from someone or a business you have dealt with. If a friend or business, that you deal with, gets a virus infection, it can make a copy of their email contact list, and send email to all people in that list.


3. Be very suspicious of any email with no subject or "RE:" as the subject. A "RE:" should always have the subject of the reply following it.


4. Be very suspicious of any email with no textual content and only a website link or attachment. Attachments can contain dangerous links to virus infected sites or an infected software executable. This is a file that once it is double clicked, can plant dangerous spyware or install malicious software.


5. Do not click on a link or attachment unless you were expecting an email from the sending person.


6. If you aren't sure about the email, it might be a good idea to call the sender. If they didn't send the email, ask them to quickly change their email account password and have their computer scanned for viruses and spyware. You should immediately delete the email.


7. To reduce the risk of your email contact list from being used to perpetrate one of these nasty email crimes, make sure you use a strong password to protect your email account. Short and simple passwords are easy to break. Secondly, install a quality antivirus software on your computer. Most people, who come into our Fort Collins, Colorado office, with a virus infected computer, were using the antivirus software, provided free, by their Internet service provider. We have found that the "big" name antivirus companies produce weak antivirus protection and also slow down your computer.

Comparison of transportation management software for 3PL

A Transportation Management System (TMS) is positioned between an Enterprise Resource Planning (ERP) system and a shipping distribution model (e.g. TL shipping). There are three ways a shipper can implement a TMS:

• Create a TMS in-house
• Outsource the TMS function to a Third Party Logistics (3PL) provider
• Use transportation management software

Large shippers that operate a shipping fleet usually create a TMS product in-house, while small shippers that do not own a fleet normally outsource the TMS function to a 3PL provider, or implement a TMS product - a type of logistics software that allows shippers to perform a freight audit as well as other logistics functions without staffing logistics experts, or contracting with a third party.

TMS Software versus 3PL
Depending on the wants and needs of the shipper, both TMS software and 3PL have unique advantages. When comparing a TMS product to a 3PL, the advantages of each-pertaining to cost, control, and carrier options-can be summed up as follows:

Cost
The cost of 3PL depends on the type of provider a shipper uses - a standard 3PL provider, a service developer, a customer adapter, or a customer developer. Standard 3PL providers and service developers offer a limited range of standard logistical services and a limited range of value-added logistical services, respectively. Therefore, they are not a logical choice for TMS management. That leaves customer developers and customer adapters, both of which perform comprehensive shipping management.
Compared to the cost of transportation management software, the cost of using a customer adapter or a customer developer can seem exorbitant. Although the management function is outsourced, it is still handled by logistics experts, who earn an average salary of $75,000-$90,000 a year.

Control
Outsourcing the TMS function to a 3PL provider relieves the shipper of controlling the function directly. This is what some shippers want, but for shippers preferring to perform their own freight audit and enjoy having control over the shipping process, using logistics software creates a happy medium. This is because it eliminates the cost of maintaining an in-house logistics department, yet it allows the shipper to control the TMS function within the company.

Carrier Options
TMS software supplies shippers with the largest number of shipping options. The number of shipping options that a 3PL provider considers is often unclear. Some providers use electronic posting systems that match available loads with available carriers, while others have beneficial business relationships with a select group of carriers, and use them for the majority of shipments. Using logistics software instead of 3PL is known to reduce shipping costs by ten percent in the first year, and the broader range of carrier options it supplies is one reason why.

Conclusion
Transportation management software provides a cost effective way for shippers to perform a freight audit along with other TMS functions, particularly when compared to maintaining a TMS product within the company. Outsourcing the TMS function to a 3PL provider is also less expensive than the in-house approach, but it does not offer the same flexibility as TMS software in terms of cost, control over the shipping process, and carrier options.

It also increases the output capacity of the computer. You can connect the output directly to the TV. In addition, it also provides a graphical output using several maps of video monitors.

It is possible to display a graphics card can cause problems because it will crash, freeze, suspend, or sometimes it is a problem, that bad things there. It is difficult to find the error occurred when the certificate of such errors. This is mainly because the card can display the same mistake, in many problems. Below are methods to find the exact problem and solution.

Write down questions video graphics cards

the following is an important tool for solving problems with the video card.

Install the latest chipset drivers:

Mobile computing Based on sensitivity to context

Mobility of the platform is based on the new concept of environment was developed. Environment that is distracted by using the concept of context. It's been a Modeling Language based on text features mobility and behavior of the program. In other words, we can say that the intersection between life beyond the digital world of social, physical and mobile. This is the understanding of the complementary fields. Sites that can serve as a determining factor for the process of population, but it can be applied more context it flexibilité and mobile computing, and all companies are moving and bring the spirit of sharing. Approved development of all computer parts, or ubiquitous computing will deal with changes in bonding environment systems,

Context-aware mobile agents has some of the most suitable for the implementation of mobile applications. This type of computer system architecture that is a new trend for embedded systems and dialog databases and services they represent, communicate, capture, interrogate and integrate users. Context-Aware Computing offers millions of dollars annually in income opportunities for some industries, including travel and retail. Awareness of the importance of signing the context in which a device or service meets the user measures like - their research and support calls. It also enables effective communication in the user environment and analysis of models of behavior. As an information delivery function, alert, and advertising in a major commercial opportunity for all service providers and content providers. Technology means the driving experience among mobile phone users than a simple search for information, and even non-existing services, based on location, corresponding to vèstij only in the context of the time.

This program is completely different mobile computing simple sensors, based on what they see on smartphones. For example, users use a program like bark on their iPhones to find restaurants close to the kitchen and place and order. Context of knowing that the device has a feature that seems to know the restaurants that the user has selected in the past, users have food. Based on these settings in the device to make recommendations for restaurants that are nearby. It could even be shared with four other applications on the device.
