Ctrl+Alt+Del ama Ctrl+Alt+Delete waa isku darka caanka ah ee 3 furayaal ee kumbuyuutarka. Waxaa loo isticmaalaa in lagu qabto hawlo kala duwan oo Windows ah sida furitaanka maamulaha hawsha ama daminta codsi shil galay. Isku dhafka muhiimka ah waxaa sidoo kale loo yaqaannaa salaanta saddexda farood. Waxaa markii ugu horreysay soo bandhigay injineer IBM ah oo lagu magacaabo David Bradley horaantii 1980-aadkii. Markii hore waxaa loo isticmaalay in dib loo bilaabo nidaamka ku habboon IBM PC.

What is Ctrl+Alt+Delete?

Takhasuska isku dhafka muhiimka ah waa shaqada ay qabato waxay ku xiran tahay macnaha guud ee loo isticmaalo. Maanta waxa ugu horrayn loo isticmaalaa in lagu qabto hawlaha maamulka ee qalabka Windows . Furayaasha Ctrl^(Ctrl) iyo Alt ayaa marka hore isku mar la riixaa, waxaana ku xiga furaha Delete .

Qaar ka mid ah isticmaalka muhiimka ah ee isku dhafka muhiimka ah^{(Some important uses of this key combination)}

Ctrl+Alt+Del waxaa loo isticmaali karaa in dib loo bilaabo kombayutarka. Marka la isticmaalo inta lagu jiro Power-on Self-Test , waxay dib u bilaabi doontaa nidaamka.

Isku-dhafka isku midka ah wuxuu qabtaa shaqo ka duwan Windows 3.x iyo Windows 9x . Haddii aad tan laba jeer riixdo, habka dib-u-kicinta wuxuu bilaabmaa iyada oo aan la xidhin barnaamijyada furan. Tani waxay sidoo kale nadiifinaysaa khasnad bogga waxayna si badbaado leh u dejisaa tirada. Laakiin ma badbaadin kartid wax shaqo ah ka hor inta uusan nidaamku bilaabin dib u kicinta. Sidoo kale, hababka socda si sax ah looma xidhi karo.

Talo: Ma ahan dhaqan wanaagsan in la isticmaalo Ctrl+Alt+Del si aad dib u bilowdo kombayutarkaaga haddii aadan rabin in aad lumiso faylasha muhiimka ah. Faylasha qaar ayaa laga yaabaa inay xumaadaan haddii aad dib u bilowdo adoon kaydin ama si sax ah u xidhin.

Gudaha Windows XP , Vista , iyo 7, isku darka waxaa loo isticmaali karaa in lagu galo akoonka isticmaalaha. Guud ahaan, sifadan waa la naafo. Haddii aad rabto in aad isticmaasho jidkan gaaban, waxa jira tillaabooyin go'an si aad awood ugu yeelato sifada.

Kuwa soo galay nidaamka leh Windows 10/Vista/7/8 waxay isticmaali karaan Ctrl+Alt+Del si ay u furaan amniga Windows -kaas . Tani waxay ku siinaysaa fursadahan soo socda - quful nidaamka, beddel isticmaale, gasho off, xidh/dib u kici ama fur Maareeyaha Hawsha^{(Task Manager)} (halkaas oo aad ka arki karto hababka firfircoon / codsiyada).

An in-detail view of Ctrl+Alt+Del

Ubuntu iyo Debian waa habab Linux ku salaysan oo aad isticmaali karto Ctrl+Alt+Del si aad uga baxdo nidaamkaaga. Ubuntu , adoo isticmaalaya habka gaaban waxaad dib u bilaabi kartaa nidaamka adigoon soo galin.

Qaar ka mid ah codsiyada sida VMware Workstation iyo barnaamijyada kale ee fog/virtual desktop, hal isticmaale si uu u soo diro fur- Ctrl+Alt+Del nidaam kale isagoo isticmaalaya ikhtiyaarka menu. Gelida isku dhafka sida aad caadi ahaan u sameyso uma gudbi doonto codsi kale.

Sidii aan horeyba u soo sheegnay, waxaa lagu soo bandhigayaa xulashooyin kala duwan oo ku jira shaashadda amniga Windows marka aad isticmaasho ^(Windows)Ctrl+Alt+Del . Liiska xulashooyinka waa la habeyn karaa Ikhtiyaarka waa laga qarin karaa liiska, tafatiraha Diiwaangelinta^(Registry) waxaa loo adeegsadaa wax ka beddelka ikhtiyaarrada lagu soo bandhigay shaashadda.

Xaaladaha qaarkood, marka la riixo badhanka Alt wuxuu qaban doonaa isla shaqada uu qabto Ctrl+Alt+Del . Tani waxay shaqeysaa kaliya haddii software-ku uusan u isticmaalin Alt qaab gaaban oo shaqo kale ah.

The story behind Ctrl+Alt+Del

David Bradley waxa uu ka mid ahaa kooxda barmaamijyada IBM kuwaas oo ka shaqaynayay samaynta kombuyuutar shaqsiyeed cusub ( mashruuca Acorn^{(project Acorn)} ). Si loola socdo tartamayaasha Apple iyo RadioShack , kooxda waxaa la siiyay kaliya hal sano si ay u dhamaystiraan mashruuca.

Dhibaatada caadiga ah ee ay la kulmeen barnaamij-sameeyayaashu waxay ahayd, markii ay la kulmeen cilad xagga codaynta, waxay ahayd inay gacanta dib u bilaabaan nidaamka oo dhan. Tani waxay dhacdaa marar badan, waxayna luminayeen waqti qiimo leh. Si arrintan looga gudbo, David Bradley waxa uu la yimid Ctrl+Alt+Del sida hab gaaban oo dib loogu bilaabo nidaamka. Tan hadda waxaa loo isticmaali karaa in dib loo dajiyo nidaamka iyada oo aan la tijaabin xusuusta, iyaga oo badbaadinaya waqti badan. Waxay u badan tahay inuusan wax fikrad ah ka lahayn sida caanka ah ee isku-dhafka furaha fudud uu noqon doono mustaqbalka.

David Bradley – the man Behind Ctrl+Alt+Del

Sannadkii 1975kii, David Bradley waxa uu u shaqo bilaabay barnaamijka IBM . Waxay ahayd waqti kombuyuutarku hadda caan noqday oo shirkado badan ay isku dayayeen inay ka dhigaan kombuyuutar mid la heli karo. Bradley waxa uu ka mid ahaa kooxdii ka shaqaynaysay Datamaster – mid^{(Datamaster – one)} ka mid ah isku daygii IBM ee ku guul daraystay ee PC.

Kadib 1980kii, Bradley wuxuu ahaa xubintii ugu dambaysay ee loo doortay Project Acorn . Kooxdu waxay lahayd 12 xubnood oo ka shaqaynayay inay PC ka dhistaan ​​meel eber ah. Waxaa la siiyay muddo gaaban oo hal sano ah si ay u dhisaan PC-ga. Kooxdu waxay u shaqeysay si deggan iyada oo wax yar ama aan lahayn faragelin dibadeed.

Ku dhawaad ​​markii kooxdu ay shan bilood jirtay, Bradley waxa uu sameeyay jidkan gaaban ee caanka ah. Waxa uu ka shaqayn jiray cilad bixinta looxyada silig-ku-duubka, qorista barnaamijyada wax-soo-saarka, iyo waxyaabo kale oo badan. Bradley ayaa^(Bradley) dooranaya furayaashan gaarka ah iyadoo ay ugu wacan tahay meelaynta ay ku jiraan kiiboodhka. Waxa ay ahayd wax aan macquul ahayn in qofna isku mar si lama filaan ah u riixo furayaasha fog fog.

Si kastaba ha ahaatee, markii uu la yimid habka gaaban, waxaa loogu talagalay oo kaliya kooxdiisii ​​​​barnaamijiyeyaasha, ma aha isticmaalka dhamaadka.

Jidka gaaban wuxuu la kulmaa isticmaalaha ugu dambeeya^{(The shortcut meets the end-user)}

Kooxda xirfadda sare leh waxay ku dhameeyeen mashruuca waqtigii loogu talagalay. Markii IBM PC lagu soo bandhigay suuqa, khubarada suuqgeyntu waxay sameeyeen qiyaaso sare oo iib ah. IBM , si kastaba ha ahaatee, waxay meesha ka saartay tirooyinka sida qiyaas rajo-xumo leh. In yar ma ay ogayn sida ay u caan baxayaan kombuyuutarradan. Waxay ahayd mid aad u soo jiidatay dadweynaha markii dadku ay bilaabeen isticmaalka PC-yada hawlo kala duwan sida dukumentiyada tafatirka iyo ciyaaraha.

Waqtigaan, dad yar ayaa ka warqabay gaabnaanta mashiinka. Waxay caan noqotay kaliya markii Windows OS uu noqday mid caan ah 1990-meeyadii. Markii kombuyuutarku burbureen, dadku waxay bilaabeen wadaagista jidka gaaban si degdeg ah. Haddaba, habka gaaban iyo isticmaalkiisu waxay ku faafeen afka. Tani waxay u noqotay nimco badbaado dadka markii ay ku dhegeen barnaamij/arji ama markii nidaamkoodu burburay. Markaas ayay saxafiyiintu hal-abuureen kelmadda 'salaanta saddexda farood' si ay u muujiyaan jidkan gaaban ee caanka ah.

2001 waxa ay ^xustay sanadguuradii 20aad ee IBM PC . Waqtigaas, IBM waxay iibisay ilaa 500 milyan oo kombuyuutar ah. Dad aad u tiro badan ayaa isugu soo baxay Matxafka hal-abuurka ee San^(Innovation) Jose Tech^{(San Jose Tech Museum)} si ay u xusaan munaasabadda. Waxaa jiray dood cilmiyeed lala yeeshay khubarada caanka ah ee warshadaha. Su'aashii ugu horreysay ee dood-cilmiyeedka waxay ahayd David Bradley oo ku saabsan hal-abuurkiisii ​​yaraa balse la taaban karo kaasoo noqday qayb iyo qayb khibradda isticmaale Windows^{(Windows user)} adduunka oo dhan.

Microsoft waxay soo bandhigtay jid-gaabkan sifo ammaan ahaan. Waxaa loogu talagalay in lagu xannibo malware-ka isku dayaya inuu galo macluumaadka isticmaalaha. Si kastaba ha ahaatee, Bill Gates ayaa sheegay in ay ahayd qalad. Doorashadiisu waxay ahayd inuu haysto hal badhan oo loo isticmaali karo gelitaanka.

Waqtigaas, markii Microsoft ay u soo dhawaatay IBM si ay ugu darto hal fure oo Windows ah oo fulin doona shaqada gaaban, codsigoodii waa la diiday. Iyada oo ubaxyada soo saarayaasha kale, furaha Windows ayaa ugu dambeyntii lagu daray. Si kastaba ha ahaatee, waxaa loo isticmaalaa oo kaliya in la furo menu-ka bilawga ah.

Ugu dambayntii, Daaqadaha^(Windows) waxaa ku jiray isku xigxiga soo gelida laba-geesoodka ah ee gelitaanka sugan. Waxay isticmaali karaan furaha cusub ee Windows iyo badhanka korantada ama isku darka hore ee Ctrl+Alt+Del . Kaniiniyada casriga ah ee Windows waxay leeyihiin sifada galitaanka ee aaminka ah ee la naafo. Haddii aad rabto in aad isticmaasho, waa in uu awood u yeesho maamulaha.

What is Ctrl+Alt+Delete? (Definition & History)

Ctrl+Alt+Del or Ctrl+Αlt+Delete is a popular combination of 3 keys on the keyboard. It is usеd to perform varioυs functіons in Windowѕ such as opening the task manаger or shutting down an application that has crashed. Τhіs key combination is also known aѕ the three-finger ѕalute. It was first introduced by an IBM engineer named David Brаdley in the early 1980s. It was initially used to restart an IBM PC-compatible ѕystem.

What is Ctrl+Alt+Delete?

The specialty of this key combination is the function it performs depends on the context in which it is used. Today it is primarily used to perform administrative functions on a Windows device. The Ctrl and Alt keys are first pressed simultaneously, followed by the Delete key.

Some important uses of this key combination

Ctrl+Alt+Del can be used to restart the computer. When used while on Power-on Self-Test, it will reboot the system.

The same combination performs a different function in Windows 3.x and Windows 9x. If you press this twice, the rebooting process starts without shutting down open programs. This also flushes the page cache and safely unmounts volumes. But you cannot save any work before the system starts rebooting. Also, processes that are running cannot be closed properly.

Tip: It is not a good practice to use Ctrl+Alt+Del to restart your computer if you do not want to lose important files. Some files may get corrupted if you start restart without saving them or closing them properly.

In Windows XP, Vista, and 7, the combination can be used to login to a user account. Generally, this feature is disabled by default. If you want to use this shortcut, there is a set of steps to enable the feature.

Those who have logged in to a system with Windows 10/Vista/7/8 can use Ctrl+Alt+Del to open that Windows security. This provides you with the following options – lock the system, switch user, log off, shut down/reboot or open the Task Manager (where you can view the active processes/applications).

An in-detail view of Ctrl+Alt+Del

Ubuntu and Debian are Linux based systems where you can use Ctrl+Alt+Del to log out of your system. In Ubuntu, using the shortcut you can reboot the system without logging in.

In some applications such as VMware Workstation and other remote/virtual desktop applications, one user to send a shortcut of Ctrl+Alt+Del to another system using a menu option. Entering the combination like you usually do will not pass it to another application.

As mentioned before, you are presented with a set of options in the Windows security screen when you use Ctrl+Alt+Del. The list of options can be customized. An option can be hidden from the list, Registry editor is used for modifying the options displayed on the screen.

In some cases, pressing just the Alt button will perform the same function that Ctrl+Alt+Del does. This works only if the software does not use Alt as a shortcut for a different function.

The story behind Ctrl+Alt+Del

David Bradley was a part of the team of programmers in IBM who were working on developing a new personal computer (project Acorn). To keep up with competitors Apple and RadioShack, the team was given just a year to complete the project.

A common problem faced by the programmers was, when they faced a glitch in coding, they had to manually restart the entire system. This would happen often, and they were losing valuable time. To overcome this issue, David Bradley came up with the Ctrl+Alt+Del as a shortcut for rebooting the system. This could now be used to reset the system without the memory tests, saving them a lot of time. He probably had no idea how popular the simple key combination would become in the future.

David Bradley – the man Behind Ctrl+Alt+Del

In 1975, David Bradley started working as a programmer for IBM. It was a time when computers had just gained popularity and many companies were trying to make computers more accessible. Bradley was a part of the team that worked on Datamaster – one of IBM’s failed attempts at a PC.

Later in 1980, Bradley was the last member chosen for Project Acorn. The team had 12 members who were working on building a PC from scratch. They were given a short duration of one year to build the PC. The team worked quietly with little or no external interference.

Almost when the team was five months in, Bradley created this popular shortcut. He used to work on troubleshooting wire-wrap boards, writing input-output programs, and a range of other things. Bradley chooses these particular keys due to their placement on the keyboard. It was highly unlikely that anyone would simultaneously press such far apart keys accidentally.

However, when he came up with the shortcut, it was intended only for his team of programmers, not for the end-user.

The shortcut meets the end-user

The highly skilled team completed the project on time. Once the IBM PC was introduced in the market, marketing experts made high estimates of its sales. IBM, however, dismissed the numbers as an overoptimistic estimate. Little did they know how popular these PCs would become. It was a hit among the masses as people started using PCs for various activities such as editing documents and playing games.

At this time, few people were aware of the shortcut on the machine. It gained popularity only when Windows OS became common during the 1990s. When PCs crashed, people started sharing the shortcut as a quick fix. Thus, the shortcut and its usage spread by word of mouth. This became a saving grace for people when they got stuck with a program/application or when their systems crashed. It was then that the journalists coined the term ‘the three-finger salute’ to denote this popular shortcut.

2001 marked the 20^th anniversary of IBM PC. By then, IBM has sold about 500 million PCs. A large number of people gathered at the San Jose Tech Museum of Innovation to commemorate the event. There was a panel discussion with renowned industry experts. The first question in the panel discussion was to David Bradley about his small but significant invention that has become a part and parcel of Windows user experience all over the world.

Microsoft and the key-control combination

Microsoft introduced this shortcut as a security feature. It was intended to block malware trying to gain access to user info. However, Bill Gates says that it was a mistake. His preference was to have one button that could be used for logging in.

At that time, when Microsoft approached IBM to include a single Windows key that would perform the function of the shortcut, their request was refused. With the bloom of other manufacturers, the Windows key was finally included. It is, however, used only to open the start menu.

Eventually, Windows included a dual login sequence for secure login. They could use the new Windows key and power button or the old Ctrl+Alt+Del combination. Modern Windows tablets have the secure login feature disabled by default. If you want to use it, it has to be enabled by the administrator.

What about MacOS?

This key combination is not used in macOS. Instead of this, Command+Option+Esc can be used to open the Force Quit Menu. Pressing the Control+Option+Delete on MacOS will flash a message – ‘This is not DOS.’ In Xfce, Ctrl+Alt+Del will lock the screen and the screensaver will appear.

Generally, the common use of this combination remains to get out of an unresponsive application or a process that is crashing.

Summary
