Awalnya saya tau tombol shortcut pada keyboard adalah untuk membuka Windows Explorer yaitu menggunakan tombol [windows]+[E] tapi setelah saya coba-coba sendiri semua tombol yang diawali tombol [windows] ternyata ada beberapa yang jalan dan berfungsi untuk memudahkan kita mengakses sesuatu hanya dengan Keyboard.
Shortcut mempermudah kita bekerja karena denga shortcut kita bisa langsung mengakses atau menjelankan seuatu perintah tanpa mencari-cari lagi program yang ingin di jalankan. So ini sangat berguna sekali buat kamu..
Baiklah berikut ini adalah beberapa shortcut pada keyboard yang bisa kamu gunakan :
Fungsi keylogger adalah untuk mengetahui segala aktivitas yang sedang di lakukan kita yang sedang ber-internet ria di warnet-warnet yang kebetulan ada orang iseng yang menyusupkan Keylogger di computer yang sedang kita mainkan.
Apa Bahaya dari keylogger?
Tentu saja Keylogger bisa membahayakan privasi kita dan ketentraman kita ber-Internet. Data-data yang kamu ketikkan akan terekam oleh keylogger seperti Username dan Password, Isi Email, Bahkan Website-website yang kita kunjungi. Bisa kamu bayangkan jika Password email kamu yang berisikan Data-data pribadi kamu seperti Nomor Kartu Kredit kamu misalnya.
Jenis Keylogger ada 2 yaitu berupa software dan Hardware, Banyak situs-situs Underground yang menyediakan Keylogger untuk dinikmati tapi kelemahan dari keylogger Software adalah Antivirus biasanya bias mengenalinya. Namun Lain halnya Hardware, hardware tidak bisa di kenali oleh Antivirus karena Keylogger jenis ini terpasang sebagai hardware di computer, contoh keylogger jenis Hardware adalah Keyboard yang bisa di beli melalui situs tertentu contonya
Mungkin anda pernah dan bahkan sering mengalamai seperti tinta sering disuntik kemudian semakin lama semakin pendek umur pemakaian tinta namun anda tidak tahu apa penyebabnya.
Semakin lama kejadian ini semakin membuat umur tinta di dalam cartrige semakin pendek sehingga membuat kita semakin sering menyuntik tinta ke dalam cartrige. Ini disebabkan oleh beberapa hal di antaranya adalah :
Terlalu seringnya melakukan penyuntikan tinta ke dalam cartrige
Kelembaban pada head cartrige tidak terjada
Mengalami kebocoran pada cartrige sehingga membuat tinta yang ada dalam cartrige semakin cepat kering
Untuk menghindari agar cartrige lebih awet dan lebih tahan lama disini saya mencoba memberikan sedikit tipsnya sebagai berikut :
Komputer saat ini memang bukan lagi merupakan kebutuhan orang berpunya tapi lebih kepada kebutuhan pokok yang harus ada khususnya bagi semua jenis bidang usaha. Memang sih masih banyak juga yang belum menggunakan komputer alias komputer manual (mesin ketik) sebagai alat untuk mengetik.
Bayangkan di jaman dulu yang belum begitu dikenalnya komputer, apabila terjadi padam listrik, maka para pegawai kantor masih bisa kerja menggunakan penerangan seadanya yaitu lilin karena pada saat itu kompunter masih jarang ditemukan, bandingkan dengan saat ini, apabila listrik padam maka semua pegawai istirahat total itu karena rata-rata di setiap bidang usaha sudah menggunakan fasilitas komputer sebagai alat kerja yang pokok, sedangkan komputer membutuhkan daya berupa aliran arus listrik sehingga apabila terjadi padam listrik kita tentu tidak bisa melakukan apa-apa kecuali menungu hingga listrik kembali dialiri.
Masalah listrik ini pun bisa memperngaruhi keselamatan dari peralatan mesin komputer kita salah satunya adalah motherboard atau mainboard.
Motherboard atau mainboard ini sangat penting untuk kelancaran proses data karena semua komponen mulai dari prosesor, memori, media penyimpan data (storage), komponen Input-Output (I/O), kartu-kartu (cards) tertancap pada mainboard ini.
Agar mainboard ini bisa lebih lama atau awet dalam pemakaian maka perlu diperhatikan tips singkat berikut ini :

Meskipun saya yakin sudah banyak situs atau blog yang sudah menuliskan tips merawat monitor lcd.
Tips untuk monitor lcd ini tidak hanya bertujuan untuk monitor lcd saja melainkan semua peralatan yang menggunakan lcd sebagai layar tampil (display) unit seperti PDA atau peralatan sejenisnya.
Berikut tips-tips yang harus diperhatikan agar monitor lcd lebih awet dan tahan lama.
Gunakan proteksi layar (screen protector) yang bisa diperoleh di toko-toko komputer untuk menghindari
Monitor adalah salah satu alat atau komponen yang sangat bermanfaat didalam dunia komputer karena monitor merupakan video display unit (VDU)yang berfungsi untuk menampilkan setiap informasi yang dihasilkan oleh central processing unit (CPU).
Untuk itu keberadaan monitor sangat menentukan komputer tersebut layak digunakan atau tidak, seandainya monitor tidak bis amenampilkan informasi meskipun cpu bekerja dengan baik namun sudah pasti bahwa tidak akan berarti apa-apa tanpa monitor.
Before fixing a Microsoft Microsoft Windows blue screen or blue screen of death error (BSoD) you must first identify what type of error it is. Since there are different types of blue screen errors.
Note: If you're getting a blue screen and then your computer immediately reboots without being able to read the text in the blue screen, follow the steps below. If you're unable to get into Windows to perform the steps below, boot the computer into Safe Mode.
In the System Properties window click the Advancedtab.
In Advanced click the Settingsbutton under Startup and Recovery.
In the Startup and Recovery window uncheck the Automatically restart check box.
Click Ok.
Blue screen errors
Windows NT, 2000, XP, Vista, and later versions of Windows will have a blue screen error that's similar to the example shown below. Thankfully these error messages often contain more detailed information, and will contain information that can be more easily searched for and found. If you're not getting a blue screen error that looks like the below skip to the next Fatal exception section.
Identify the type of blue screen by locating a line containing all capital letters with underscores instead of spaces, such as the above example: BAD_POOL_HEADER. Write this information down.
Get either the STOP: error message at the top of the error, or in the "Technical Information:" portion of the error. For example, in the above error it's STOP: 0x00000019 ... write the first potion of this error message down.
Finally, if technical information is shown write down the file and the address.
Once you have the above information you can start troubleshooting the issue.
Many of the blue screen error messages you'll encounter with earlier versions of Windows will be fatal exception error messages or Fatal 0E messages. If your blue screen message starts out with A fatal exception 0E ... or An exception ... you're encountering this error. For these blue screen errors we suggest going through the steps on document CH000223. Below is an example of this type of error.
If for the course very expensive network, and should take another also cisco certificate, for that I membagi2 science that could be used as possible;
Own learning pairs of UTP cable for network
Tutorial
This brief is perfect for you who are making the network
computers 'cheap', especially of more than two clients pake
hub (much cheaper than a router). To the point! What cable
UTP that? UTP cable is a special cable for data transmission. UTP, stands for "unshielded Twisted Pair". Called
unshielded because less resistant to electromagnetic interference.
Twisted pair and called for its cable partners
aka spiral arranged berlilitan each. There are 5 categories of UTP cable. From category 1 to category 5. For the well-known computer network is a category 3 and category 5.
Categories
3 can be used for data transmission up to 10 mbps, while the category 5 to
100 mbps. If only for such computer networks in offices or
campus or a cafe, the most efficient use of category yes 3. The
already more than cukup.Setahu
author there are many brands on the market, only the
famous stubborn and relatively inexpensive is Belden brand - made in USA.
If you want a cheaper and use a lot, then buy it
one box, approximately 150 meters long. Do not forget to buy
connector. Connector plug shaped like a phone only
greater. Just tell me want to buy RJ-45 connectors.
Photo of RJ - 45 who are still new, not yet in gencet pake tang
One
again a very important, you must have a special pliers for installing
connector to the UTP cable, the term term is "Crimp tool". This tool
point to 'turn off' or 'planting' connector to UTP cable. Be
it was the 'star', then it can not be removed again connector.
And if you want a more OK, I'll not bear the same buy a
LAN tester. You can buy the brand from Taiwan just to make it more
cheap. Shaped like a box and its LED lights and eight pairs
be sealed and off.
OK
udah equipment ready now, writers start. In general,
UTP cabling is there are two types, namely type of straight and
type of cross. Type is called straight because each cable
8 numbers 1-1 that correspond directly. While called a cross
because there are crosses on the composition of the cord. Confused? OK!
For the straight type is used to connect the cable from the client
to the hub. As for the type of cross is to direct client
connected to the client (cpu to cpu) or also from hub to hub.
We first discuss the types of straight
Type
This is most easily made. Why? Because direct
corresponding 1-1. Standard order this (viewed from the hole
connectors, from left to right - see Figure 4): 2 orange - green 1 - 2
blue - green 1 - 2 brown. 2
orange orange here means young couples same old orange and
onwards. But do not come standard staining was also true
no problem. The important sequence cord. For example the first end of the sequence
young orange pin first, then the other end of the first pin sequence
too young to orange, so between the end of each disconnected. Actually, not all pins are used.
A
important is the pin numbers 1,2,3 and 6. So for example, which are connected only
pins 1,2,3 and 6 while the other pins are not installed, not so
trouble. For more details please see the picture below the
author photo from a book.
Who left the order for the type of correspondence straight, the right is a cross
Time
would put it, the cut end of the cord, then arrange the cord
trus flattened with a knife cut on Crimp tool. Andak
not have to bother to release the insulation at the end of the cable,
because when you insert the cable into the connector and pressed
(pressed) by using Crimp tool, it is time that pin
in the connector to penetrate into the cable. Consider, for
penekannya (pressing) is hard, because if not hard sometimes pin
it does not penetrate into the cable insulation. If it was then
Your test using the LAN tester. Insert the tip end of the cable to the
device, then switch it on, if the light that led to the LAN tester
burn all, from number 1 to 8 means that you have been successful. If
there is one that does not work means the possibility of the pin number
is a problem. The simplest way is that you press (press) more
using pliers. Possible pins not penetrating. If you have
press but still does not connect, then check to see corresponding
udah between pins 1-1 or not. If it is correct and still
fail, then indeed you are not lucky. Repeat again until it works.
LAN TESTER - a tool to check the cable connection is correct or not. For the type of straight if true then 1 to 8 led is blinking.
Here
is the image of the bottom of the end of the UTP cable that have been fitted
connectors and works well (the pin go coloring sequence
standard):
standard pin order
And
if that is not standard, consider the sequence of color pins,
is not standard, but still could be, an important
corresponding one-one (special type of straight):
NOT pin standard sequence
Cross Type
For the type of cross was used to connect directly between the two
PC, or are generally used to connect between the hub.
(eg for plugs in the hub is less). How to install also
really easy, just like a straight type, pin is used also
actually it is only 4 pins, namely pins 1, 2, 3 and 6. Different
is how to pair. If the type of cross, pin 1 is connected to pins
3 other end, pin 2 to 6, pin 3 to pin 1 and 6 to 2. Practical
this, the first end of the pin you can set up standards for
the type "straight", while at the other end you are collated
create a standard pin type "cross". Still confused? Here's how easy it is: The first tip:
1. young orange
2. old orange
3. green
4. blue
5. navy
6. dark green
7. brown
8. sepia
So at the other end should be made like this:
1. green
2. dark green
3. young orange
4. blue
5. navy
6. old orange
7. brown
8. sepia
Already
a little more understanding? So here's position number 1, 2, 3 and 6 are
exchanged. Later when tested using the LAN tester, then later led 1,
2, 3 and 6 will be exchanged. If menyalanya straight type sequence,
while there are cross type jumping. But that would be
menyalasemua each led from the numbers 1 to 8.OK, congratulations to build computer networks. Hopefully
You can work when installing the connector on the cord. Good science
This is useful for you, because when the first author had made
network hilarious results, to strip the cord authors still
using a cutter, but had no facilities in toolnya Crimp.
In addition the ends of each cable peel authors again use
cutter, but that did not need to peel one-one, let alone
average, because later when the 'Crimp tool' then these pins
each will penetrate into the cord. Hopefully you do not
doing the same thing as writing dulu.Demikian authors on how to make UTP cable connection to computer networks. May be useful for you all. Thank you.
