Answer:

Explanation:

The oldest operating system is Version 6 Unix 1975 and the next is 1BSD 1977, then we can find the Apple DOS 1978, in several years we have Mac OS (System 1.0) 1984, in 1985 was born one of the most popular OS in the world Windows 1.0, and Linux version 0.01-0.1 is the newest in 1991.

Nowadays we can find other system like android, windows 10 or Chrome OS.

Sql is an example of a ________ category programming language. 4gl 3gl 5gl 2gl

kicyunya [14]

The answer is Fourth-generation language (4GL). Sql is an example of a 4GL category programming language. SQL is considered a Fourth-generation language (4GL), whereas Java and C++ are third-generation languages (3GLs). Fourth-generation languages are programming languages that are closer to human language than the high-level languages like Java.

What is an 8086 microprocessor used for

Liula [17]

A sixteen bit microprocessor chip used in early IBM PCs. The Intel 8088 was a version with an eight-bit externaldata bus.

The Intel 8086 was based on the design of the Intel 8080 and Intel 8085 (it was source compatible with the 8080)with a similar register set, but was expanded to 16 bits. The Bus Interface Unit fed the instruction stream to theExecution Unit through a 6 byte prefetch queue, so fetch and execution were concurrent - a primitive form ofpipelining (8086 instructions varied from 1 to 4 bytes).

It featured four 16-bit general registers, which could also be accessed as eight 8-bit registers, and four 16-bit indexregisters (including the stack pointer). The data registers were often used implicitly by instructions, complicatingregister allocation for temporary values. It featured 64K 8-bit I/O (or 32K 16 bit) ports and fixed vectored interrupts.There were also four segment registers that could be set from index registers.

The segment registers allowed the CPU to access 1 meg of memory in an odd way. Rather than just supplyingmissing bytes, as most segmented processors, the 8086 actually shifted the segment registers left 4 bits and addedit to the address. As a result, segments overlapped, and it was possible to have two pointers with the same valuepoint to two different memory locations, or two pointers with different values pointing to the same location. Mostpeople consider this a brain damaged design.

Although this was largely acceptable for assembly language, where control of the segments was complete (it couldeven be useful then), in higher level languages it caused constant confusion (e.g. near/far pointers). Even worse, thismade expanding the address space to more than 1 meg difficult. A later version, the Intel 80386, expanded thedesign to 32 bits, and "fixed" the segmentation, but required extra modes (suppressing the new features) forcompatibility, and retains the awkward architecture. In fact, with the right assembler, code written for the 8008 canstill be run on the most recent Intel 486.

The Intel 80386 added new op codes in a kludgy fashion similar to the Zilog Z80 and Zilog Z280. The Intel 486added full pipelines, and clock doubling (like the Zilog Z280).

So why did IBM chose the 8086 series when most of the alternatives were so much better? Apparently IBM's own engineers wanted to use the Motorola 68000, and it was used later in the forgotten IBM Instruments 9000 Laboratory Computer, but IBM already had rights to manufacture the 8086, in exchange for giving Intel the rights to its bubble memory designs. Apparently IBM was using 8086s in the IBM Displaywriter word processor.

Other factors were the 8-bit Intel 8088 version, which could use existing Intel 8085-type components, and allowed the computer to be based on a modified 8085 design. 68000 components were not widely available, though it could useMotorola 6800 components to an extent.

REY [17]

Answer:

True

Explanation:

Building your personal brand requires extreme care when it comes to social media presence. In the age of internet there is nothing hidden, so whatever you post or comment will be seen by your audience and it can go in either way. It can either make your brand or break it. It is of utmost importance to leave a pleasant and positive impact on your audience. One should not indulge in inappropriate or controversial debates and try to avoid being too personal on social media.
