What is XT microprocessor?
The IBM Personal Computer XT, often shortened to the IBM XT, PC XT, or simply XT, is a version of the IBM PC with a built-in hard drive. It was released as IBM Machine Type number 5160 on March 8, 1983. Apart from the hard drive, it was essentially the same as the original PC, with only minor improvements.
What is the difference between an XT and an AT computer system?
In this verbiage, PC stands for personal computer; XT stands for an extended PC; and AT stands for an advanced-technology PC.
What is XT class?
Xt-class meaning The first-generation of PCs. Using an 8-bit system bus, XT class machines included the floppy disk-based IBM PC, the hard disk-based IBM PC XT and all the PCs made by other companies using an Intel 8088, 8086 or compatible CPU.
When was the first virus released?
The first computer virus, called “Creeper system”, was an experimental self-replicating virus released in 1971. It was filling up the hard drive until a computer could not operate any further. This virus was created by BBN technologies in the US.
Who introduced XT?
IBM
On March 8, 1983, IBM released the Personal Computer XT, short for eXtended Technology, or PC/XT, or just XT. It came equipped with a 10 megabyte MFM Full-Height Hard Disk Drive with 306 Cylinders, 4 Heads, and 17 512-byte Sectors, was expandable to 640k of RAM on the Motherboard, and came with MS-DOS v2.

What does ISA stand for computer?
Instruction Set Architecture
An Instruction Set Architecture (ISA) is part of the abstract model of a computer that defines how the CPU is controlled by the software. The ISA acts as an interface between the hardware and the software, specifying both what the processor is capable of doing as well as how it gets done.
What is CMOS battery function?
The CMOS battery powers your laptop’s BIOS firmware, which is responsible for booting up your computer and configuring data flow. You can tell if your CMOS battery has died if your laptop has difficult booting up, if drivers disappear, and if your laptop’s date and time are incorrect.
What does XT mean?

Who made virus?
The Brain Boot Sector Virus Brain, the first PC virus, began infecting 5.2″ floppy disks in 1986. As Securelist reports, it was the work of two brothers, Basit and Amjad Farooq Alvi, who ran a computer store in Pakistan.
When did the 8086 processor come out?
Intel 8086. The Intel 8088, released July 1, 1979, is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs ), and is notable as the processor used in the original IBM PC design, including the widespread version called IBM PC XT .
What are some examples of computers with 8086-2 processors?
The later Olivetti M24SP featured an 8086-2 running at the full maximum 10 MHz. The IBM PS/2 models 25 and 30 were built with an 8 MHz 8086. The Amstrad PC1512, PC1640, PC2086, PC3086 and PC5086 all used 8086 CPUs at 8 MHz. The NEC PC-9801. The Tandy 1000 SL-series and RL machines used 9.47 MHz 8086 CPUs.
What does 8086 stand for?
The 8086 (also called iAPX 86 ) is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released.
What is the bus size of 8086 microprocessor?
Buses and operation. All internal registers, as well as internal and external data buses, are 16 bits wide, which firmly established the “16-bit microprocessor” identity of the 8086. A 20-bit external address bus provides a 1 MB physical address space (220 = 1,048,576).
