The IBM 1401 is a variable-word-length computer introduced by IBM in 1959, primarily used for business data processing. It was notable for its affordability and versatility, often used in accounting and administrative tasks. The 1401 utilized magnetic core memory and could be programmed using punch cards and magnetic tape. Its influence on computing was significant, paving the way for subsequent IBM systems and contributing to the development of more advanced programming languages.

The IBM PC is significantly more powerful than the IBM 1401 due to its advanced microprocessor architecture, which allows for faster data processing and multitasking capabilities. While the IBM 1401 relied on vacuum tube technology and had limited memory capacity, the IBM PC utilized integrated circuits, enabling greater efficiency and scalability. Additionally, the PC supported a wider range of software applications and provided better graphics and input/output options, making it more versatile for modern computing tasks.
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.

That depends on which computer character set you are talking about as there are several (and there were many more in the early days, before things were standardized).A few examples are given in the following table:Character Set Letter "A" ASCII 1000001 EBCDIC 11000001 Fieldata 000110 UNIVAC I 010100 IBM 1620 0100 0001 IBM 1401 110001 IBM 650 01 01000 00 00001 Hollerith 100100000000 Baudot 00011
