Every employer require certain skills for certain jobs but almost every employer would love a potential employee to possess basic computer skills in addition to other skills.
In this technology era where using the internet to communicate and search for information is vital for most people as well as businesses, not having basic computer skills can hamper your chances of getting a good job, a contract or even marketing your products/services online. Even searching for jobs online and sending emails to people require basic computer skills. Imagine if you were asked to send an information to someone in another country, won't you prefer sending an email rather than writing a long letter that might take days to arrive?. Of course, you would prefer an email.
Having basic computer skills will save you lots of hassle and delays. Moreover, you can search for any information that you want on the internet without waiting for anyone to do it for you.
It is NEVER too late to start. Learning is a continuous process.
