IBM 1401 is the first computer in nepal
The National Computer Center of Nepal had an IBM 1401 at least several years before 1978. It was use for many purposes including census and Royal Nepal Airlines. It was certainly the first large computer used there.

The IBM Selectric typewriter was first introduced in July 1961. It was one of the most successful typewriters of that generation. The line was replaced in 1984 with the IBM Wheelwriter.
Pakistan International Airlines purchased and installed the first computer in Pakistan. This took place in 1967, and the computer was an IBM 1401.
Some of the more widely known second generation computers were:IBM 7090IBM 7070IBM 7080IBM 7010IBM 7030 StretchIBM 1620IBM 1401IBM 1410IBM 1440UNIVAC IIIUNIVAC Solid State (used some tubes, some transistors, and lots of FERRACTOR magnetic amplifiers)UNIVAC 1107DEC PDP-1DEC PDP-6Minuteman I Guidance ComputerCDC 1601CDC 3600CDC 6600CDC 7600etc.
In 1973, IBM developed the Winchester computer drive
IBM 5100 (LAPTOP) was a portable computer introduced in September 1975, by the IBM Corp.
As the IBM 1620 was introduced by IBM in 1959 there were many programmers long before 1964.
The IBM Personal Computer, commonly known as the IBM PC, is the original version and progenitor of the IBM PC compatible hardware platform. It is IBM model number 5150, and was introduced on August 12, 1981.
IBM was the company that introduced the personal computer. The acronym IBM PC stands for an International Business Machine Personal Computer.
From what I can gather, the IBM Portable Computer was introduced in 1975 at a selling price of $9000 and weighed about 50 lbs.
IBM introduced the first personal computer (PC) in the fall of 1981, causing a dramatic increase in the microcomputer market.

Varied widely depending on requirements of the computer.The IBM 1620 a small scientific computer had from 1500 to 5000 transistors in the CPU depending on options included.The IBM 1401 a small business computer had about 10000 transistors in its CPU.The IBM 7030 Stretch a supercomputer had about 170000 transistors.The CDC 6600 a supercomputer had about 384000 transistors.The CDC 7600 a supercomputer had about 2900000 transistors.You can compare this to first generation computers, the largest of which the IBM AN/FSQ-7 had about 50000 vacuum tubes.You can compare this to modern multicore microprocessor based computers, a typical one of which has a couple hundred billion transistors per processor core integrated on one chip.
Binary is what digital computers operate on, yes.Most use binary, but some have used decimal using various encodings. Some decimal machines were:ENIACUNIVAC IUNIVAC IIIBM NORCIBM 702IBM 705IBM 7010IBM 7070 familyIBM 7080IBM 1401 familyIBM 1620etc.
First IBM PC (Personal Computer) was IBM model number5150, which was introduced on August 12, 1981.IBM's first electronic digital computer was the 701 Defense Calculator, introduced in 1952.IBM's first computer was the Harvard Mark I, in 1942, but it was electromechanical.
Second generation computers (transistorized computers) varied in size from about the size of a two drawer file cabinet (e.g. Autonetics RECOMP-II) to occupying a significant part of a room (e.g. IBM 7090, IBM 7030 Stretch, UNIVAC III, UNIVAC 1107, DEC PDP-10). The image above shows the prototype for the IBM 1620, a transistorised computer roughly the size of an office desk, introduced in 1959.
OS/2 is a computer operating system, initially created by Microsoft and IBM, then later developed by IBM exclusively. The name stands for "Operating System/2," because it was introduced as part of the same generation change release as IBM's "Personal System/2 (PS/2)" line of second-generation personal computers.
The first computer printers were just existing electromechanical accounting machines, modified to connect to the computer instead of printing from punchcards. They were introduced on the earliest commercially available first generation computers (e.g. UNIVAC I, IBM 701, IBM 702).Because they were very slow compared to the computer, in many cases they were actually connected "indirectly": the computer wrote the text to a magnetic tape then the operator took the magnetic tape to an offline tape drive that read it and sent the text to the printer.
