Top10 things every computer user must to know.

10. Set Up a Simple Backup System



We all know we should back up our computers, but it’s always one of those things that you’ll set up “one day”. Setting up a backup only takes minutes, though, so you can do it right now and forget about it until you need it—and when you do need it, you’ll be glad you set it up. If you’re just backing up to an external drive, you can just use the simple tools built in to your computer, like Windows Backup or Apple’s Time Machine. However, that’ll only keep you safe if your computer fails. If you lose your home in a fire, get all your gear stolen, or experience any other kind of disaster (God forbid), you’ll have lost all those important documents, family photos, and other files forever. So, we recommend using a service like CrashPlan to back up your computer online. That way, it can back up no matter where you are, and that data will be safe no matter what happens to your hardware.

9. Do Everything Faster with Shortcuts



The great thing about computers is that they can do a lot of things much faster than a human. Say you’re looking for a specific word on a web page. Instead of scanning it yourself, all you need to do is press Ctrl+F and type the word you’re looking for. There are mountains of shortcut like this, from pressing Ctrl+S to instantly save the file you’re working on, Ctrl+P to print it out, or Ctrl+T to open a new tab in your web browser. It may seem like more trouble than its worth at first, but after you use a shortcut one or two times, you’ll wonder why you ever did anything with the mouse. Check out our list of six shortcuts everyone should know, as well as our shortcut of the dayseries for even more tricks.

Computer software, or simply software, is that part of a computer system that consists of encoded information or computer instructions, in contrast to the physical hardware from which the system is built.

The term "software" was first proposed by Alan Turing and used in this sense by John W. Tukey in 1957. In computer science and software engineering, computer software is all information processed by computer systems, programs and data.

Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media. Computer hardware and software require each other and neither can be realistically used on its own.

At the lowest level, executable code consists of machine language instructions specific to an individual processor—typically a central processing unit (CPU). A machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also (indirectly) cause something to appear on a display of the computer system—a state change which should be visible to the user. The processor carries out the instructions in the order they are provided, unless it is instructed to "jump" to a different instruction, or is interrupted.

The majority of software is written in high-level programming languages that are easier and more efficient for programmers, meaning closer to a natural language.[1] High-level languages are translated into machine language using a compiler or an interpreter or a combination of the two. Software may also be written in a low-level assembly language, essentially, a vaguely mnemonic representation of a machine language using a natural language alphabet, which is translated into machine language using an assembler.

“Watanzania wanataka mabadiliko, wasipoyapata ndani ya CCM watayatafuta nje” >>>> Hii ni moja ya sentensi ambazo Waziri Mkuu Mstaafu na Mbunge wa Monduli, Edward Ngoyai Lowassa aliziongea Arusha May 30 2015 alipotangaza nia ya Kugombea Urais kupitia CCM.

CCM ilikuwa na Wagombea zaidi ya 40 ambao walitangaza nia na kuchukua fomu za Kugombea Urais 2015 lakini baadae Chama hicho kikampitisha Dk. John Pombe Magufuli kugombea nafasi hiyo, baada ya hapo kukawa na headlines nyingi sana kuhusu ishu ya Edward Lowassa na UKAWA.

Viongozi wa Umoja wa UKAWA wamekutana Dar na mmoja wa Viongozi hao, James Mbatia amesema wamekubaliana kumkaribisha Mbunge Edward Lowassa ndani ya UKAWA na wako tayari kumpa nafasi na kushirikiana nae.

‘UKAWA tunahitaji viongozi wenye sifa, uwezo na weledi katika kulinda kuheshimu na kusimamia rasilimali za Taifa… Tunamwalika Edward Lowassa ajiunge na UKAWA na tuko tayari kushirikiana nae kuhakikisha tunaing’oa CCM madarakani kwenye Uchaguzi Mkuu ujao.. Tunaamini ana uwezo wa kuhamasisha umma kuikataa CCM na udhalimu wake‘ >>>> James Mbatia.

Zimeandikwa stori nyingi kuhusu Mbunge huyo kujiunga CHADEMA, kingine kilichoibua maswali mengi ni ishu ya UKAWA kuchelewesha kumtaja Mgombea wao wa Urais… hapa ziko picha mbili zilizoenea Mitandaoni zikimwonesha Mbunge Edward Lowassa pamoja na Viongozi wa UKAWA, kuna chochote kinafuatia?
